LOW-COST ADJUSTABLE AUTOMATIC IRRIGATION SYSTEM BASED ON SOIL MOISTURE AND WATERING TIME USING A SINGLE ARDUINO MEGA2560 FOR DRY LAND CULTIVATION
Accurate watering is an important aspect of optimum plant growth. It is necessary to continuously obtain the soil moisture status as the basis for watering time. Real-time monitoring can play an important role in monitoring the readily available moisture in the soil. This paper presents the adjustable automatic soil moisture control design for dry land cultivation based on soil moisture and watering time. We used a low-cost capacitive sensor and Real Time Clock 1307 as soil humidity and timer sensors. The automatic control employs a single Arduino Mega2560 microcontroller for a data acquisition system, including a real-time clock, memory card, keypad, display, and irrigation actuators. The calibration was based on the soil sensor voltage provided by the capacitive sensors and the measured soil moisture content using the Gravimetric method. Then, the calibration model is embedded in the Arduino. The range of desired points of soil moisture and watering time could be set and adjusted using the keypad. There are three default set points of soil moisture (i.e., 40% to 42%, 60% to 62%, and 80 to 82%) and watering time (08:00, 12:00, and 17:00).

READINESS FOR CHANGE OF BANTARSARI VILLAGE RESIDENTS TOWARDS CLIMATE CHANGE
Climate change is a global phenomenon that affects humans' lives in many ways. Lifestyle shifts are inevitable to sustain the vulnerable environment affected by climate change, and people in rural areas are no exception. Therefore, those people's readiness for change towards this lifestyle must be measured to prepare for the future. This research investigates the readiness for change of Bantarsari Village residents in the viewpoint of community involvement using a quantitative method of SEM-PLS. We use a questionnaire to gather data from Bantarsari Village residents as the population of this research, and the population is divided into four categories: gender identity, age, occupation, and education. The questionnaire contains 26 questions using a five-point psychological scale from "strongly disagree" to "strongly agree" about lifestyle change, participation, and preferences towards sustainable life. The results show that community involvement is significantly correlated with readiness for climate change where 99.3% of the readiness is affected by community involvement. This research result can be used to raise awareness among the government or related stakeholders that people in rural areas should also participate in sustainable life to face climate change.
SUSCEPTIBILITY OF GERMAN COCKROACH, Blattella germanica TO ORGANIC INSECTICIDES BASED ON THE ENTOMOPATHOGENIC FUNGI Beauveria bassiana
German cockroaches have been reported to have developed resistance to 42 active insecticide ingredients. One effort to minimize the development of resistance in German cockroaches is to use organic insecticides, one of which is a secondary metabolite from the entomopathogenic fungus Beauveria bassiana (B10). The purpose of this study was to determine the susceptibility of German cockroaches to secondary metabolites of B. bassiana B10 as organic insecticide. This study used an experimental method with a completely randomized design consisting of ten treatments, namely concentrations of 0, 0.1, 0.5, 1, 5, 10, 20, 30, 40, and 50% (v / w). Each treatment unit used ten male German cockroaches which were repeated three times. Mortality data were analyzed using ANOVA followed by Duncan's test at a significance level of p <0.05. The results showed that the application of organic insecticide B. bassiana B10 was quite effective in controlling German cockroaches as indicated by the mortality of German cockroaches. The application of B. bassiana B10 secondary metabolites affect the mortality of German cockroaches with a concentration of 40 % with a mortality percentage of 50%.

THE WEAK SUBSTITUTION IN COMPLEX NUMBERS OVER THE SYMMETRIZED MAX-PLUS ALGEBRA
The complex numbers over the symmetrized max-plus algebra is an extension of numbers in the symmetrized max-plus algebra. This complex number is formed by defining an imaginary form in the symmetrized max-plus algebra. The substitution process in complex numbers over the symmetrized max-plus algebra is a very important concept and cannot be done as in complex numbers over the conventional algebra. Thus, several algebraic properties are needed to ensure that the substitution process can be carried out. In this paper, we show the substitution rules in complex numbers over the symmetrized max-plus algebra. These rules is formulated by extending the weak substitution property in the symmetrized max-plus algebra. The extension was carried out in the symmetrized max-plus algebra part and imaginary part of complex numbers. The results obtained are the weak substitution in complex numbers over the symmetrized max-plus algebra. Substitution process can be carried out in complex numbers if both of the symmetrized max-plus algebra part and imaginary part of complex numbers are signed elements. Then, according the weak substitution property, it can be derived the weak transitive property in complex numbers over the symmetrized max-plus algebra. Furthermore, it can be also derived reduction of balance property in complex numbers over the symmetrized max-plus algebra, which reduce balance relation into equal relation sense.
SEDIMENTOLOGY OF THE UPPER MERAWU FORMATION, CIKADU AREA, NORTH SERAYU RANGE, CENTRAL JAVA: IMPLICATION FOR TECTONIC ACTIVITY AND HYDROCARBON EXPLORATION
The Upper Merawu Formation in the Cikadu area of the North Serayu Range, Central Java, presents a complex geological and sedimentological framework shaped by tectonic and sedimentary processes. This study aims to analyze the stratigraphy, lithofacies, and depositional environments of the Upper Merawu Formation through detailed geological mapping, lithofacies analysis, and micropaleontological examination. The Upper Merawu Formation is composed primarily of alternating sequences of shale, fine-grained sandstone, and tuffaceous sandstones, with distinct sedimentary structures including parallel laminations, cross-stratifications, and hummocky cross-stratification. These lithofacies indicate deposition in a marine setting ranging from distal shelf to shoreface environments. Thrust faults and folds dominate the region's structural geology, consistent with regional tectonic activity. This research provides new insights into the sedimentation and tectonic history of the North Serayu Range, suggesting significant tectonic influence during the Miocene to Pliocene period. These findings contribute to the broader understanding of the depositional systems within the Serayu Basin, with implications for hydrocarbon exploration in the region.
THE POLITICS OF TERRITORIAL MITIGATION LAW: RELATIONS IN POST-MINING COASTAL AREA MANAGEMENT
The state's orientation in coastal area management is based on the constitution. Mitigation of coastal areas is an integral part of territorial management. Policies related to environmental management are oriented towards the derivative impacts caused after mining activities in coastal areas. Problems arise when there are changes in environmental quality standards after mining. Some of the problems discussed are whether the direction of environmental policy is based on the concept of sustainable development and how is the post-mining monitoring mitigation pattern carried out by policy makers? This research uses normative juridical research methods. The results of the research conducted are legal politics related to environmental protection in coastal areas in general often changes along with changes in the power phase with legacy orientation of achieving success but not based on the root of the problem. Environmental management mitigation instruments in coastal areas are more directed towards state responsibility through the government, causing a high burden and a long range of power related to policy patterns so that it is often late in dealing with problems at the grassroots. Problems of coastal area management can be done through the concept of a comprehensive solution based on grassroots problems that can be resolved at the regional level evaluated by the central government. Environmental problem solving must be carried out based on integrative sustainable development patterns so that it will minimize the impact of derivatives on environmental quality standards.
BUILDING ECONOMIC INDEPENDENCE OF SRIDADI VILLAGE, SIRAMPOG DISTRICT BREBES REGENCY THROUGH ARABICA PRODUCTS
Sridadi Village, Sirampog District is one of the villages producing Arabica Coffee in Brebes Regency. So far, the cultivation results produced by coffee farmers are still sold in the form of cherry coffee which has a low economic value, which is less than IDR 8,000. There is a small part that has been processed into green beans and roast beans, but still on a small scale and household scale. Even then, they still use traditional mortar and pestle tools. In addition to the conventional cultivation methods, during the main harvest there are difficulties in drying the harvest, due to high humidity and rainfall. Due to these conditions, the village empowerment team (PDB) of the Universitas Peradaban and Unsoed funded by DRTPM in the first year (2024) carried out community service through various training, workshops and appropriate technology grants. In the implementation of appropriate technology, 1 unit of pulper (wet seed peeler) with a capacity of 150 kg/hour, Huller (dry seed peeler) with a capacity of 100 kg/hour and a greenhouse measuring 54 m2 (6 m x 9 m) have been donated. The results of this service have increased the production capacity of peeling at least 6 times previously from 150 kg/day to 900 kg/day. And the dry peeling capacity of 100 kg to 600 kg/day. For drying, it is also efficient because farmers no longer need to lift and dry coffee in the afternoon or when it rains. Farmers only need to turn it over so that the dryness is evenly distributed. With the greenhouse system, it also dries faster because the heat is stored and trapped, and the capacity increases 3 times because the drying is arranged in 3 layers.
STUDY OF HIGH SULFIDATION-EPITHERMAL DEPOSIT IN THE VOLCANIC ENVIRONMENT : A CASE STUDY IN BANJARHARJO AREA, AYAH DISTRICT, KEBUMEN REGENCY, CENTRAL JAVA
Indications of hydrothermal deposits have been found in Ayah District, Kebumen Regency, Central Java. In this area, there are products from the ancient volcanic activity of Menganti which has an age from Oligocene to Miocene. The existence of volcanic activity makes hydrothermal deposits can develop and have the potential to produce metal minerals. This study aims to identify the characteristics of alteration and mineralization that are developing in the research area. The methods used in the research are in the form of surface geological mapping and rock sampling for laboratory analysis in the form of Petrography, Mineragraphy, SEM (Scanning Electron Microscopy), Atomic Absorbtion Spectophotometry (AAS) and XRD (X-Ray Diffraction). The stratigraphic conditions of the research area from old to young consist of Dacitic Tuff Breccia, Andesite Lava, and Andesite Intrusion. The developing alterations are in the form of propylitic (Chl+Smc), argilic(Kao+Ill-Smc), advanced argillic(Kao+Alunite-Diaspor-Dickite-Barite), and silicification (Si-Qtz). The presence of ore minerals such as enargite, chalcocite and covellite is an indicator that high sulphidation alteration type mineralisation is developing in this area. The alteration and mineralization of the research area are controlled by the geological and lithological structure of the rock, where there are horizontal faults in the southeast-northwest direction and horizontal faults in the southwest-northeast direction. Andesite intrusion arises through the activation of the fault so that it can alter the rock it passes through. Based on AAS analysis there are also levels of economically valuable minerals, especially gold (Au) of 203.122 ppm and copper (Cu) of 2,500.05. Based on the alteration and mineralization characteristics from the results of laboratory analysis, the epithermal deposits in the study area have a high sulfidation type.

ASSESSING THE IMPACT OF VARIABLE FOOD SECURITY ON POVERTY REDUCTION: A COMPARATIVE ANALYSIS OF INCOME PER CAPITA
This research examines the relationship between food security and poverty reduction, focusing on the role of income per capita. By analyzing data from various regions with differing levels of food security, we aim to understand how fluctuations in food availability and access affect poverty rates. Our research reveals that while higher income per capita can contribute to reduced poverty, it is the stability and reliability of food security that play a crucial role in sustaining poverty reduction efforts. The findings highlight the importance of integrated policies addressing both income inequality and food insecurity to effectively combat poverty. The study's insights can inform policymakers in developing strategies to enhance food security and reduce poverty, ultimately improving overall well-being
DO EXCHANGE RATES, INFLATION AND AGRICULTURAL CREDIT MATTER FOR FARMERS' TERMS OF TRADE? EMPIRICAL EVIDENCE OF ASYMMETRIC EFFECTS IN INDONESIA
The role of farmers in the agricultural sector as food providers is very significant and is still relied upon as a livelihood. This study aims to analyze the determinants of farmers' terms of trade (FTOT) as a measure of welfare for farmers in Indonesia. The study applies the Nonlinear Autoregressive Distributed Lag (NARDL) model for monthly data from January 2010 to December 2023. The NARDL model is applied to capture the asymmetric effects of FTOT determinants. The results show that an increase in inflation decreases FTOT, while an increase in the food industry production index increases FTOT in the long run. Meanwhile, in the short run, rupiah depreciation, an increase in inflation and a decrease in credit decrease FTOT. Inflation is the most significant factor determining farmer welfare. Stabilizing inflation at controlled levels is key to maintaining the purchasing power of farming households. Sectoral linkages with the food industry as users of agricultural sector inputs also support farmer welfare. Monetary policy with a focus on inflation stabilization and agricultural development policies integrated with the industrial sector will greatly encourage farmer welfare
EFFECT OF GLOBAL ENERGY AND FOOD PRICES AND EXCHANGE RATE ON ENERGY AND NON-ENERGY IMPORT DEMAND: EMPIRICAL EVIDENCE FROM INDONESIA
This research aims to analyze the effect of changes in global energy and food prices and exchange rates on demand for oil and gas and non-oil and gas imports in Indonesia. This research applies the Autoregressive Distributed Lag (ARDL) model to capture long-run and short-run effects. The research period taken was 2012M01 – 2023M02. Empirical findings show that in the long run, global oil prices, food prices, and exchange rates have a negative effect on demand for oil and gas imports in Indonesia. Meanwhile, global food prices have a negative effect on non-oil and gas imports. Indonesia, which still depends on imports of non-oil and gas commodities, especially food imports, will be vulnerable to food inflation problems caused by food imports. In the short run, the influence of oil prices and exchange rates on oil and gas imports is distributed over several months. Meanwhile, coal prices and the exchange rate have a negative effect on non-oil and gas imports. In the short run, imports of oil and gas and non-oil and gas commodities, which tend to be uncontrolled by changes in world commodity prices and exchange rates, need to be a concern for policymakers in reducing the impact on domestic inflation. The trend of non-oil and gas imports that are increasing all the time needs to be of concern to the government regarding the impact of rising global commodity prices and the depreciation of the local currency on domestic inflation through imports
ANALYSIS OF CULTURAL ADAPTATION FACTORS AFFECTING THE SUCCESS OF THE HIGHER EDUCATION AFFIRMATION PROGRAM (ADik)
This study aims to analyze the cultural adaptation factors that affect the academic success of Papuan students who are members of the Higher Education Affirmation Program (Adik) at Jenderal Soedirman University, focusing on three main aspects, namely psychology, sociology, and academic aspects. The subject of this research is a Papuan student of the ADik Program who is currently undergoing studies at Jenderal Soedirman University. This study uses a qualitative approach with a survey method by collecting data through in-depth interviews, questionnaires, and observations. The results of the study show that psychological adaptations, such as stress management and motivation, have a great influence on the academic achievement of Papuan students. Sociological factors, including social support from fellow Papuan students and positive interactions with students from other regions also play an important role in building a sense of comfort and connectedness in the campus environment. From an academic perspective, difficulties in understanding lecture material and adjusting to different evaluation and teaching systems require additional support, such as tutoring programs and tutoring with peers. This study concludes that the academic success of Papuan students in the ADik Program is not only determined by cognitive ability, but also by their success in adapting psychologically, socially, and academically

ANALYSIS OF MILT QUALITY AND TESTIS HISTOLOGICAL FEATURE OF POST-SPAWNING BAWAL (Colossoma Macropomum)
The research aims to observe several reproductive parameters of Bawal/pomfret fish after spawning. Data on milt quality parameters were crucial for determining the readiness of male parent for successful spawning, while ensuring female parent has reached sexual maturity. The observation results on the quality of post-spawning male Bawal from week 0 (M0) to week 3 (M3) are as follows, milt volume=0.1 - 1.75 ml, Milt pH=6 - 7, sperm motility=35 - 100%, and the density or number of spermatozoa ranged from 2.03 x 1011 cells/ml (M0) to 3.56 x 1011 cells/ml (M2). Furthermore, the length of spermatozoa ranged from 40 to 60 μ, with a head length of only 2-3 μ. Supporting data on GMI of male parents was 2.57% (M0) - 4.02% (M2). The histological observations of testicular development showed that all stages of spermatogenesis were visible from M0 to M3 preparations, including spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids, and spermatozoa. The proportions of each stage of spermatogenesis are as follows, (in %): M0 (spg=13.5; sp=15.3; ss=17.8; smt=15.1; spz=63.2); M1 (spg=5.3; sp=4.2; ss=10.6; smt=14.4; spz=61.2); M2 (spg=5.2; sp=6.3; ss=9.9; smt=9; spz=55.1); M3 (spg=6.0; sp=5.0; ss=30.5; smt=17.1; spz=52.5). Despite the good quality status of milt and GMI, only 4 out of 24 post-spawning male Bawal produced milt during stripping (M0-1, M0-2, M2-4, and M3-4), while the other 20 did not. This correlated with data obtained from Bawal farmers in Banyumas, Central Java, who reported that during the dry season, male Bawal had difficulty preparing for spawning, even when their reproductive quality status was relatively good
THE RELATIONSHIP BETWEEN EXTERNAL BODY DIMENSIONS AND BODY WEIGHT OF MALE SAKUB SHEEP AT DIFFERENT PHYSIOLOGICAL AGES
Sakub sheep are a type of local Indonesian livestock which is starting to be widely cultivated in Brebes Regency. The productivity of Sakub sheep can be assessed based on the appearance of livestock production, namely external body dimensions (chest girth, body length, shoulder height) and body weight. Therefore, it is necessary to conduct research on the relationship between external body dimensions and body weight of male Sakub sheep. The research was conducted using 118 male Sakub sheep (59 lambs and 59 rams) with purposive random sampling at October-December 2023 in Pandansari Village, Paguyangan District and Wanareja Village, Sirampog District, Brebes Regency, Central Java. The number of research samples was determined using the Harry King Nomograph formula. The research data were analyzed using multiple linear regression analysis. External body dimensions (chest girth, body length, shoulder height) have a very strong and significant relationship, can be used as predictors in estimating body weight of male Sakub sheep. Chest girth and body length are significant body measurements in explaining and predicting body weight of male Sakub sheep, while shoulder height is not significant. Body length is the most significant body measurement in explaining and predicting body weight of male Sakub sheep at lambs, while chest girth at rams
POTENTIAL DRUG-DRUG INTERACTION IN ELDERLY PATIENTS IN TREATMENT WITH ANTIHYPERTENSIVE
Antihypertensive medications are often used in combination.

Regression results showed that fast food consumption, visceral fat and physical activity simultaneously affect blood cholesterol with a correlation coefficient of 0.09; 3.22; -0.04, respectively. Conclusion: Fast food consumption, percent body fat, visceral fat and physical activity are correlated with blood cholesterol.
STUDY OF PYROCLASTIC BRECCIA WEATHERING IN PRENDENGAN VILLAGE, PAWINIHAN MOUNTAIN, BANJARMANGU, BANJARNEGARA
The lithology of pyroclastic breccia is the lithology that forms the basis of the rock in the Pawinihan mountain landslide that occurred in 2006. This landslide resulted in a large number of victims, more than 80 people died. The landslide occurred in the weathering of the Rogojembangan pyroclastic breccia rock in Banjarnegara Regency. So to find out the weathering factors that affect landslides, a study was carried out on the degree of weathering of pyroclastic breccias. The degree of weathering of pyroclastic breccias plays an important role in supporting the occurrence of landslides because the slip surface is at the degree of weathering. The method used is the identification of the level of weathering with the standard British method for heterogeneous materials. The result obtained is that there is a weathering degree of one to six that can be observed in the field. And the slip surface occurs at weathering levels 3 and 4, so that this weathering level is used as the limit of the slip surface for landslides in pyroclastic breccias.

THE IMPACT OF SOCIAL MEDIA MARKETING ON THE MARKETING PERFORMANCE OF CULINARY MSMES IN BANYUMAS
This research investigates the impact of social media marketing strategies on marketing performance, with a focus on the mediating role of social media performance within food micro, small, and medium enterprises (MSMEs) in Banyumas. Utilizing a quantitative approach, data were collected from a sample of food MSMEs and analyzed through Structural Equation Modeling (SEM) with Partial Least Squares (PLS) methodology. The findings reveal that two hypotheses were accepted: first, social media marketing strategies positively influence marketing performance; second, social media performance significantly affects marketing performance. Conversely, two hypotheses were rejected: social media marketing strategies do not have a direct effect on social media performance, and social media performance does not serve as a mediating variable between social media marketing strategies and marketing performance. These results underscore the complexity of the relationship between social media marketing and performance metrics in the context of culinary MSMEs, suggesting that while direct marketing strategies are effective, the anticipated mediating role of social media performance is not supported in this study. The implications of these findings provide valuable insights for practitioners aiming to enhance marketing effectiveness through social media channels.

GROWTH AND SURVIVAL IN FOUR COLOR VARIANTS OF Procambarus clarckii FRY REARED IN A RECIRCULATING SYSTEM
Procambarus clarckii is a freshwater lobster with several body colors and is one of the commodities in demand by ornamental lobster hobbyists. Like the Crustacea subphylum, its growth begins with periodic skin changes. Its survival plays a role in lobster cultivation. The research aimed to examine the growth and survival of P. clarckii in blue, orange, brown, and white colors. It was maintained for two months with a recirculation system and fed commercial pellets. The research was designed in a Completely Randomized Factorial with eight treatment combinations and three replications. The treatments were in different initial lengths, between 2.0-2.5 cm (A) and 3.0-3.5 cm (B). The parameters observed were the frequency of molting and survival rate. The study results showed that during two months of observation, P. clarckii with four different body colors experienced skin changes 6-7 times in treatment A and 5-6 times in treatment B. The highest survival rate occurred in orange lobster, followed by brown, blue, and white lobsters in treatments A and B with water quality conditions that were suitable for the required water quality standards such as temperature, TDS, pH, and DO, both in lobster and filtration-recirculation containers.
ANALYZING THE NEEDS OF FINANCIAL STATEMENTS FOR VILLAGE-OWNED ENTERPRISES TO IMPROVE THE EFFICIENCY
This study aims to analyze the need for financial statements in Village-Owned Enterprises (BUMDes) in order to improve efficiency in the preparation and reporting of financial statements. BUMDes, which manage various business units, such as trading, rental services, telecommunications, savings and loans, and clean water management, face challenges in terms of effective and accurate financial recording and reporting. Different types of expenses, income, assets, liabilities, and equities must be carefully recorded to ensure transparent, accountable, and accountable financial statements. This study found that BUMDes financial recording is currently still semi-manual, with the use of Microsoft Excel as the main tool. This shows the need for a more integrated and automated accounting system, in order to minimize recording errors and increase efficiency. In addition, the limited ability of human resources to use digital technology is one of the obstacles that hinders the process of preparing efficient financial statements. Therefore, continuous training and mentoring are needed in the use of modern accounting technology. The recommendations of this study include increasing the use of digital technology, training staff in managing technology-based financial statements, and the implementation of a cloud-based accounting system that can be integrated with other functions such as inventory and project management. With these measures, BUMDes is expected to improve the efficiency and accuracy of their financial statements, which in turn will support transparency and accountability in village financial management.

FIELD PERFORMANCE OF SUGARCANE cv. PSJT 941 PUTATIVE MUTANT RESULTED FROM GAMMA RAY CO60-IRRADIATION
A study has been carried out to evaluate the field performance of twenty clones of gamma ray Co60-induced putative mutant of PSJT 941 Sugarcane cultivar in PT Perkebunan Nusantara IX field, Pemalang Indonesia. This research has been carried out to 1) evaluate the growth difference between mutant and wild type clones of PSJT 941 sugarcane cultivar; 2) determine the clone which shows the best field growth. This research has been carried out experimentally using 20 putative mutant clones produced from gamma ray Co60 irradiation and one wild type clone, with 5 replications. The variable observed was the sugarcane growth, with the parameters measured include number of siblings, plant height and stem diameter. The research results showed that the putative mutants showed highly significant differences in terms of number of siblings and plant heights, and significantly different in terms of stem diameter, compared to the wild type. Clone 941.1.7 was promising, which showed an average number of siblings of 5 siblings/plant, a plant height that was 28.8% shorter than the control plant, the largest average of stem diameter of 30.2 mm, a greater tolerance to drought, and has the potential to become an early maturing sugarcane. Further research is needed to re-confirm those putative mutants.
LEGAL IMPLICATIONS OF AUTOMATICALLY ISSUED PERMITS IN A RISK-BASED BUSINESS LICENSING SYSTEM
This study aims to analyze and explain the risk-based business licensing process and the legal implications of licenses that are issued automatically in the risk-based business licensing system. This research used juridical-normative research methods with a statutory and conceptual approach. Based on the research results, the Job Creation Law divides business licensing based on the level of business risk and business scale. Business actors first register their business activities through O.S.S. to obtain the N.I.B. (Business Identification Number). The business licensing document for low-risk is the N.I.B., and for low to medium-risk, it is the N.I.B. and Standard Certificate, which are automatically issued after the business actor provides a self-declare. Business licensing documents with medium to high risk are the N.I.B. and Standard Certificate, while for high-risk are the N.I.B. and Permit. The Standard Certificate and Permit are issued after verification. The implications of the automatically issued N.I.B. and Standard Certificate as an Administrative Decision have eliminated the opportunity for government agencies or officials to make decisions and take actions in government administration. This results in confusion when determining the object of dispute against administrative lawsuits filed by the public whose interests are affected by the issuance of the N.I.B. and automatically issued Standard Certificates.
THE ABILITY OF NITRIFYING BACTERIA IN THE BIODEGRADATION OF ORGANIC WASTE AT DIFFERENT INCUBATION TIMES
Nitrifying bacteria play a key role in converting ammonium into nitrate, which helps eliminate foul odors and increase nitrate availability during composting. This study aimed to determine the effect of the addition of nitrifying bacterial consortium and varying incubation times on organic waste degradation, as well as to identify the nitrifying bacterial isolates involved. This research was conducted using a completely randomized design with a factorial pattern. Data were analyzed using ANOVA followed by the Tukey HSD test. Identification of nitrifying bacterial isolates was conducted based on Bergey's Manual of Systematic Bacteriology. The results showed that the nitrifying bacterial consortium of SA14, SA37, BA26, and BA38 could oxidize ammonium but had no significant effect on the increased nitrate content. However, the incubation time and its interaction with the bacteria significantly increased the nitrate content of the compost. The highest nitrate content was achieved at the interaction of bacterial consortium and 42 days incubation at 0.304 ppm. Phenotypic characterization identified isolates SA14 and SA37 as belonging to the genus Nitrosomonas, BA26 as a species of the genus Nitrobacter, and BA38 belonging to the genus Nitrococcus.
ISOLATION AND SCREENING OF BACTERIA WITH PLANT GROWTH PROMOTION TRAITS FROM IRON SAND SOILS OF CENTRAL JAWA SOUTH COAST
Isolation and screening of bacteria with plant growth-promoting traits from iron sand soils have been conducted. The traits examined included nitrogen fixation, IAA production, phosphate and potassium solubilization, and siderophore production. The physical and chemical properties of the iron sand soil of Central Java's south coast showed that air and soil temperatures were 31–39°C and 29–35°C, pH levels ranging from 6.5 to 7.8, and humidity levels between 15% and 100%. Sixteen bacterial isolates were identified, with population densities ranging from 5.0 x 10² to 3.5 x 10⁵ CFU. g-1 of soil. Out of these, 11 isolates demonstrated nitrogen-fixing abilities. Two isolates, PS2Y2 and KS1C4, produced IAA at concentrations of 20.6 ppm and 11.73 ppm, respectively. All isolates were capable of solubilizing phosphate, with solubilization index (SI) ranging from 1.09 to 2.81. One isolate, CS1P1, exhibited a strong ability to solubilize potassium, with an SI value of 6.39. Additionally, three isolates PS3Y4, KS1K1, and CS1P1 were able to produce siderophores.
TITLE: TREE CLASSIFICATION BASED ON TREE RING QUALITY IN CENTRAL JAVA
In Central Java Indonesia, many tropical trees don't produce distinct rings. This has caused difficulties in defining tree rings for dendrochronology. The quality of tree rings is very important to know the past environmental conditions including climate, weather, rainfall, disease, and fire. The purpose of this study was to classify wood based on the quality of tree rings. The method used in this study was a survey in Banyumas, Cilacap, Purbalingga, Banjarnegara and Wonosobo, Central Java. The material used were samples of wood pieces from felling in the area. Furthermore, the assessment of the ring quality was carried out by polling and sending questionnaires to respondents to assess each tree species. Each ring consisting of early wood and late wood was observed under a microscope. The results of this study indicate that there are three groups of trees, namely trees with: 1) Very distinct annual rings including Pinus merkusii, Melia azedarach, Toona sureni, and Hevea brasiliensis, 2) Medium annual rings including Swietenia mahagoni, Hibiscus tiliaceus, and Persea americana, 3) unclear or absent tree rings including Gnetum gnemon, Parkia speciosa, and Baccaurea racemosa. An important finding that can be concluded is that the majority of distinct annual rings come from medium to high lands.
HYDROLYSIS OF SOYBEAN PROTEIN WITH ANTIOXIDANT ACTIVITY BY FRACTIONATED PROTEASE FROM Bacillus subtilis B298
Research has been carried out to obtain bioactive peptides with antioxidant potential from soybean protein.

UTILIZATION OF BIO-AGENCY AND ORGANIC FERTILIZER ON FOOD CROP MANAGEMENT IN UNPREDICTABLE CLIMATE CHANGE: A REVIEW
Climate change cannot be predicted with precision, so the aspects of mitigation and adaptation in food crop agriculture are merely plans and actions based on data regarding climate factors, land, as well as plant growth and production. The success of adapting food crops is a triumph of the farmers' mindset and the agricultural field advisors. Several key aspects determining the success of food crop adaptation can be traced through articles from both journals and textbooks; among them are the use of biological agents and organic fertilizers to enhance soil quality functions and strengthen plants in food crop production. This article is a review of various journals and textbooks. Actually, farmers are gradually implementing mitigation and adaptation strategies to cope with unpredictable climate changes, resulting in very distinctive planting patterns in response to shifting climate disruptions. The use of biological agents and organic fertilizers has indeed been proven to enhance soil quality and the resilience of food crops. This review uses the SWOT comparison method of relevant articles and is linked to survey base research on food agriculture practises. Biotic agents such as nitrogen-fixing organisms, phosphate solubilizers, and secondary metabolite producers play a synergistic role with the use of organic materials as fertilizers and soil amendments.

PHYSICAL PROPERTIES OF POLYVINYL ALCOHOL/CASSAVA STARCH COMPOSITE BIOPLASTICS WITH NANOCELLULOSE ADDITION FROM CASSAVA PEEL
This research was conducted to investigate the characteristics of bioplastics produced from a combination of polyvinyl alcohol (PVA) and cassava starch with the addition of nanocellulose filler derived from cassava peel. The basic bioplastic formula used was 5.4% PVA and 0.6% cassava starch. The treatment applied was the amount of nanocellulose added, namely 0%, 2%, 4%, and 6%. The composite bioplastics were made by casting method, followed by testing of physical properties including thickness, water vapour transmission rate (WVTR), and transparency. Bioplastic thickness was measured using a digital micrometer, while WVTR was measured using the gravimetric method. The transparency of the bioplastics was evaluated through measuring their transmittance using a UV-Vis spectrophotometer. The results showed that the addition of nanocellulose had no effect on the physical properties of bioplastics. Increasing nanocellulose concentration tends to increase the thickness and decrease the water vapour transmission rate of bioplastics. However, the addition of nanocellulose reduced the transparency of the bioplastics, especially at higher concentrations.

Bananas (Musa sp.) are vital horticultural crops in Indonesia, where the Banana bunchy top virus (BBTV) poses a major threat. Previous studies have identified Pentalonia caladii as a potential vector for BBTV. This research examined the preferences of P. caladii among four banana cultivars: Kepok, Cavendish, Raja, and Tanduk, and evaluated its transmission potential as a BBTV vector on Raja and Kepok cultivars. A Completely Randomized Block Design (CRBD) was used for the experiments, and the data were analyzed with ANOVA and LSD tests at a 5% significance level. The findings showed that P. caladii preferred the Tanduk cultivar most, followed by Raja, Kepok, and Cavendish. Additionally, P. caladii exhibited a mild capacity to transmit BBTV with an incubation period of about 19.6 days on cv. Raja and 29.6 days on cv. Kepok, with the average of disease incidence 33.3-40%. These findings suggest that P. caladii could reproduce well on banana and serve as a vector for BBTV.
FROZEN GRANULATION OF ETHANOL EXTRACT OF BROWN OYSTER MUSHROOM (Pleurotus cystidiosus): MYCOCHEMICAL PROFILE BASED ON FOURIER TRANSFORM INFRARED (FTIR) AND ANTIBACTERIAL ACTIVITY
Brown oyster mushroom (Pleurotus cystidiosus) is a group of edible mushrooms found in many tropical countries. The utilization of P. cystidiosus mushrooms is still limited to daily food applications; even though they have much potential, they are developed into antioxidant, anti-inflammatory, or immunomodulatory supplements. In addition, manufacturing preparations from mushrooms to obtain bioactive compounds is still widely done by extraction methods with the principle of maceration. The maceration method takes a long time and wastes solvents, requiring high costs. Based on this, this study was conducted to prepare a frozen granulation of P. cystidiosus using freeze drying. The extraction process was carried out by sonication using a sonicator at a frequency of 50 Hz for 45 minutes for three running cycles, identifying the content of bioactive compounds using Fourier Transform Infrared (FTIR), and testing the activity of P. cystidiosus granules as antibacterial against four pathogenic bacterial species namely Staphylococcus aureus, Escherichia coli, Listeria monocytogenes, and Pseudomonas aeruginosa. Using the disc method. The research method was descriptive-analytical, where the results of compound identification were characterized and identified with an FTIR instrument. At the same time, antibacterial testing was carried out using the MIC macro-broth dilution method with a complete randomized design (CRD) with further tests using the Duncan-multiple range test using SPSS software ver. 27.0 and GraphPad Prism Ver 10.3.0. The results showed that the frozen granule of P. cystidiosus mushroom contained many diverse compounds and had the potential to be further developed and isolated to P. cystidiosus granules, which can also inhibit the growth of four types of pathogenic microorganisms used in antibacterial testing. The development of P. cystidiosus granule preparation can be continued by encapsulating it using a suitable coating and can be continued to be carried out in vivo testing.

Other content as antioxidants to prevent the emergence of free radicals, its flour has the potential to be immunostimulant and antimalarial. The ability of this microalgae to produce various sustainable products is not yet balanced with the development industry that meets biomass needs. The purpose of this study was to determine the effect of fertilizer types on the production of S. platensis microalgae biomass and to determine the cultivation media that can produce the highest cell biomass. This study used an experimental method with a Completely Randomized Design. The treatments tried were the kind of fertilizers, namely grow more, KW21, liquid organic fertilizer, and eco enzyme. Replications 5 times. The variables observed were the independent variables, namely the kind of fertilizer given, and the dependent variable was cell biomass. Supporting parameters were light, pH, and brightness. Biomass data were analyzed by the F-test to determine the effect of treatment and continued with the LSD test to determine the differences between treatments. The results of the study showed that the treatment of fertilizer types caused the S. platensis cell biomass to be different. Media with KW21 fertilizer produced the highest S. platensis biomass.
EFFECT OF THE ADDITION OF BLACK TEA, LEMONGRASS, LIME, AND LEMON ON THE SENSORY CHARACTERISTICS OF KECOMBRANG FLOWER TEA (Etlingera elatior)
Tea is a popular beverage consumed after water, largely due to the health benefits associated with it. The kecombrang plant (Etlingera elatior) is known to contain biochemical compounds such as alkaloids, saponins, tannins, phenolics, flavonoids, triterpenoids, steroids, vitamins, minerals, and glycosides. Kecombrang flower tea is an innovative product aimed at optimizing the use of kecombrang flowers. This tea has a red color, along with a distinctive taste and aroma, which may require the addition of other ingredients like black tea, lemongrass, lime, and lemon to enhance its organoleptic quality. The purpose of this study was to determine the effect of adding black tea, lemongrass, lime, and lemon on the sensory characteristics of kecombrang flower tea through a hedonic test. A completely randomized design (CRD) was employed in this study, with the factor under investigation being the addition of variants such as black tea, lemongrass, lime, and lemon. The tested variables included a hedonic test to assess the level of panelist preference for color, taste, aroma, and overall attributes. The results indicated that the addition of these variants significantly affected consumer preference. The sample of kecombrang flower tea with the addition of black tea was the most preferred by the panelists.
