This research discusses the effect of coconut dregs compost (Cocos nucifera L.) on the growth and yield of tomato plants (Solanum lycopersicum L.) cultivated using polybag media. This research is motivated by the importance of utilizing organic waste, especially coconut dregs, which has not been utilized optimally. Coconut dregs contain organic materials and nutrients that have the potential to increase soil fertility and improve the structure of the planting medium, so it is expected to support the vegetative and generative growth of tomato plants. The research design used was a Randomized Block Design (RBD) with six treatments and four replications. The treatments given were different doses of coconut dregs compost, namely P0 (control without compost), P1 (100 g/polybag), P2 (200 g/polybag), P3 (300 g/polybag), P4 (400 g/polybag), and P5 (500 g/polybag). The parameters observed included plant height, stem diameter, fresh weight, number of fruits per plant, root length, and estimated yield per hectare. The results showed that the application of coconut pulp compost significantly affected several growth parameters, such as plant height, stem diameter, and fresh weight. However, no significant effect was found on the number of fruits per plant or yield per hectare. The most prominent response was seen in the root length parameter, which showed a significant increase with increasing compost dosage. From the observations, the best treatment was at a dosage of 300 g/polybag (P3), which provided an optimal balance between vegetative growth and potential generative yield.

The use of organic materials as fertilizers is an important effort to improve soil fertility and crop productivity sustainably. Gliricidia sepium (gamal leaves) is a leguminous plant rich in nutrients such as nitrogen, phosphorus, and potassium, and contains bioactive compounds and microbes that support plant growth. Liquid organic fertilizer (LOF) made from fermented gamal leaves offers advantages including ease of application, high nutrient absorption by plants, and environmental friendliness compared to synthetic chemical fertilizers that may cause pollution and other negative impacts. This study aimed to evaluate the effect of LOF from gamal leaves on the growth and yield of Japanese cucumber (Cucumis sativus L.). The research was conducted at the Experimental Garden of the Faculty of Agriculture, UKI Toraja, South Sulawesi, from April to July 2025. The LOF was produced by fermenting gamal leaves for 15 days using EM-4 solution and palm sugar as activators. The LOF was applied three times at two-week intervals, starting at 7 days after planting (DAP), by soil drenching around the base of the plants. Observed variables included plant height, number of leaves, leaf area, stem diameter, number of fruits per plant and per plot, average fruit diameter and length, and fruit weight per plant and per plot. Data were analyzed using analysis of variance (ANOVA) and the Honestly Significant Difference (HSD) test at a 0.05 significance level. The results showed that application of LOF from gamal leaves at a dose of 300 ml per plant produced the best results across all observed parameters, including plant height, leaf number and area, stem diameter, fruit number, fruit size, and fruit weight per plant and per plot.

Oil palm plantations play a vital role in Indonesia’s economy; however, the dominance of monoculture practices has led to environmental and social issues such as land degradation and unstable farmer incomes during the replanting period until the first harvest (TM1). To address these challenges, the oil palm–pineapple intercropping system has been developed as an alternative strategy to improve land-use efficiency, income diversification, and farming sustainability. This study aims to: (1) analyze the influence of land size, farmer age, farming experience, and rainfall on the productivity of the intercropping system; (2) develop sustainable landscape management strategies using SWOT and SWOT matrix analysis; and (3) provide data-driven policy recommendations to support sustainable oil palm plantations. The research methods include multiple linear regression analysis for socio-economic variables, correlation analysis for environmental factors (rainfall), and SWOT analysis to evaluate Strengths, Weaknesses, Opportunities, and Threats  of the intercropping system. The results indicate that land size has a significant positive effect on production, while farming experience shows a significant negative effect. Rainfall has a strong positive correlation with yields, and SWOT analysis positions the intercropping system in a progressive quadrant with promising Opportunities for development. In conclusion, the oil palm–pineapple intercropping system has the potential to enhance productivity, stabilize farmer incomes, and support environmental sustainability. Therefore, diversification-based management strategies and supportive policies are essential to Strengthen the welfare of local communities.

Community Service (Kukerta) is a form of student community service that aims to apply knowledge, build social awareness, and encourage positive change in the surrounding environment. This article discusses the role of Kukerta Group 44 students from UIN Sultan Maulana Hasanuddin Banten in environmental conservation efforts and increasing educational awareness in Cibojong Village, Serang Regency. The majority of the population in Cibojong Village earn their living as farmers, but the agricultural produce obtained is generally only sufficient to meet daily needs, without guaranteeing long-term economic sustainability. Therefore, students educate the community through guidance from the BPP (Agricultural Extension Center), about learning to farm for the long term, and invite them to join the farming community. In addition, the community’s education level is relatively low, with most children only completing elementary school. Through a participatory approach and qualitative descriptive methods, students implement various programs such as planting productive trees, waste management education, and socialization of sustainable agriculture. In the field of education, students hold tutoring activities, motivational classes, and literacy for village children and adolescents. The results of the activity show that the active involvement of students has a positive impact on increasing public awareness of the importance of protecting the environment and continuing education. Kukerta is an effective means of building collaboration between universities and village communities to address local challenges sustainably.

This study aims to utilize data mining techniques, specifically the K-Nearest Neighbors (KNN) algorithm, to classify leaf diseases in sugarcane (Saccharum officinarum). Early and accurate detection of leaf disease types is a crucial step in prevention and control strategies, thereby reducing potential crop losses caused by pathogen attacks. Leaf diseases in sugarcane, such as leaf scald, rust, and mosaic virus, are known to affect photosynthesis, inhibit growth, and reduce the quality and quantity of sugarcane produced. The classification process in this study was carried out through image analysis of infected sugarcane leaves, where features such as color, texture, and shape were extracted using digital image processing techniques. The KNN algorithm was chosen because of its non-parametric nature, ease of implementation, and its ability to provide accurate classification results even with limited data size. The working principle of KNN is to determine the class of a new sample based on the majority class of its k nearest neighbors in the feature space, making it very suitable for the case of leaf disease image classification. In addition to building a classification model, this study also examines disease prevention strategies based on the identification results. These strategies include the use of disease-resistant sugarcane varieties, the implementation of appropriate planting patterns, land moisture management, regular plantation sanitation, and the measured and environmentally friendly use of pesticides or fungicides. Model performance evaluation was conducted using accuracy, precision, recall, and F1-score metrics to assess model effectiveness across various data scenarios. The results of this study are expected to not only contribute to the development of decision support systems for farmers and related parties but also support the application of artificial intelligence-based technology in the agricultural sector.

Environmental character education from an early age is a strategic step in developing a generation that cares about the natural world. Instilling this value is crucial in concrete ways so that children can understand and directly experience the benefits of protecting the environment. One effort undertaken is through a simple hydroponic learning activity involving children from TKS Kartika V 16. The activity was held once at the Samarinda State Agricultural Polytechnic with the support of lecturers as resource persons. Through a hands-on learning method, the children were introduced to how to grow lettuce and bok choy using a simple hydroponic system. The learning process included an introduction to tools and materials, an explanation of the planting stages, and plant care. Observations throughout the activity showed high enthusiasm among the children. They were actively involved, from preparing the planting medium, planting the seeds, to providing air and nutrients to the plants. This activity fostered a sense of care and responsibility for the plants they grew themselves. Furthermore, the children's fine motor skills were also demonstrated through activities such as arranging the planting medium, sowing the seeds, and assembling the hydroponic equipment. This activity not only developed individual skills but also taught social values such as cooperation and mutual assistance. Children learn to work in groups, help each other, and appreciate each other's roles in the planting process. This hands-on, hands-on approach has proven effective in strengthening environmental awareness in a fun and contextual way. Therefore, environmental education through hydroponics can be a practical, inspiring, and easy-to-implement learning medium for young children, while also serving as a concrete example of how character education can go hand-in-hand with the introduction of environmentally friendly technologies.

This study aims to examine the use of cattle waste as organic fertilizer to minimize agricultural operational costs in Mrawan Village, Tapen District, Bondowoso Regency. Cattle waste, particularly manure, is an abundant local resource that has not been optimally utilized by the local community. The majority of farmers in the village still rely on chemical fertilizers, which are relatively expensive and have a negative impact on long-term soil health. Therefore, this program is designed to provide a sustainable alternative solution through an educational approach and community empowerment. The methods used in this activity include outreach, technical training, and direct assistance in the process of making organic fertilizer from cow manure. Education focuses on simple fermentation techniques, the composition of natural additives, and appropriate fertilizer application methods. Farmers are actively involved in every stage of the activity, so they become not only beneficiaries but also agents of change in environmentally friendly agricultural practices. The results of the activity indicate that the use of organic fertilizer from cattle waste can reduce the cost of purchasing chemical fertilizers by up to 40% in a single planting season. In addition, organic fertilizer has been shown to increase soil fertility, improve soil structure, and support healthier plant growth. Environmental impacts are also reduced, as livestock waste management is more controlled and does not pollute water or air sources. Therefore, utilizing cattle waste as organic fertilizer not only reduces environmental pollution but also provides an economic and ecological solution that benefits local farmers. This program is expected to become a model for empowerment that can be replicated in other areas with similar characteristics.

The low proportion of Grade A harvest quality in Hokkaido corn farming remains a challenge for horticultural agribusiness practitioners. This study aims to develop an operational strategy based on a managerial evaluation of key production factors to improve technical efficiency and harvest quality. The research was conducted at PT Agricole Indonesia Makmur, Cianjur, using data from 24 planting periods in 2024. Six production input variables were analyzed to identify the most influential factors on yield quantity and quality. The results show that only three variables watering frequency, organic fertilizer, and plant age at harvest consistently contributed significantly to the production of Grade A output. Although these variables are inelastic, they play a critical role in maintaining quality. The proposed strategy includes a 10% increase in harvest quantity and a 30% conversion from Grade B to Grade A. Simulation results indicate an additional 7.67 kg of Grade A yield per planting period, generating a value increase of IDR 239,490. The strategy is considered feasible with a positive Return on Investment (ROI) of 14.04% assuming a Grade A selling price of IDR 35,000/kg.

The People’s Palm Oil Replanting Program (PSR) is a national policy aimed at improving the productivity of smallholder plantations through the replanting of aging and unproductive oil palm trees. This study reviews the implementation of PSR in Indonesia by analyzing ten scholarly articles through a literature study approach. The findings indicate that program effectiveness is significantly influenced by technical support such as training, mentoring, the application of Good Agricultural Practices (GAP), and strategic partnerships for harvest absorption. However, implementation faces several challenges, including limited human resources, damaged equipment, inadequate funding, prolonged replanting periods, weak coordination among stakeholders, and lack of policy dissemination. Local institutions such as cooperatives (KUD) and farmer groups (Gapoktan) play crucial roles in ensuring program sustainability and inclusiveness by acting as managers and conflict mediators. Although farmers are generally ready and actively participate, regulatory constraints—particularly the requirement of financial guarantors—remain a barrier. The study recommends strengthening local institutional capacity, enhancing stakeholder synergy, and simplifying financial schemes as strategic steps to improve the long-term effectiveness of the PSR program.

The purpose of the study was to analyze the study of Chili Pepper Farming and Farmer Income in Dawi-Dawi Village, Wonggeduku District, Konawe Regency. The sampling method used in this study was the census method. The census method is a method that takes one population group as a sample as a whole and uses a structured questionnaire as the main data collection tool to obtain specific information, where the respondents are all farmers who have been sampled in this study. so that the number of samples in this study was 10 people. To solve the research problem, namely by using a qualitative descriptive method. The agribusiness system of Chili Pepper farming production in Dawi-Dawi Village, Wonggeduku District consists of upstream to downstream subsystems.

On-farm substem/cayenne pepper cultivation in Dawi-Dawi Village starts from land preparation, planting, fertilizing, weeding/replanting, pest control and harvesting. While the downstream/marketing subsystem, cayenne pepper farmers sell their production directly to middlemen at a price of Rp 55,000 per kilogram.

This study aimed to evaluate the effect of chitosan-based liquid organic fertilizer (LOF) at various concentrations on the growth of cocoa seedlings (Theobroma cacao L.). The research was conducted at PTPN I Regional 5, Kendenglembu Plantation, Banyuwangi, for four months using a Completely Randomized Block Design (RCBD) with five treatments: P0 (control), P1 (10 mL/L), P2 (20 mL/L), P3 (30 mL/L), and P4 (40 mL/L). Growth parameters observed included plant height, stem diameter, and number of leaves up to 12 Weeks After Planting (WAP). ANOVA analysis showed no statistically significant effect of the treatments on any parameter. However, descriptive data indicated that concentrations of 20–30 mL/L tended to produce better growth: P2 (31.25 cm) had the highest plant height, P3 (6.93 mm) the highest stem diameter, and P1 (12 leaves) the most leaves. Chitosan potentially acts as a plant growth stimulator by increasing nitrogen availability and enhancing physiological processes such as photosynthesis. In contrast, a high concentration (40 mL/L) exhibited inhibitory effects. Although the differences were not statistically significant, concentrations of 20–30 mL/L could be recommended for practical application. The lack of significant results may be attributed to suboptimal concentrations, application frequency, or environmental conditions. Further studies are recommended to modify treatments and assess additional parameters such as biomass, root development, and leaf area to better understand the efficacy of chitosan fertilizer in cocoa seedling growth.
