The agricultural sector plays a strategic role in meeting food needs while maintaining environmental sustainability and community welfare. However, conventional farming practices that rely on chemical inputs have caused various problems, such as soil degradation, loss of biodiversity, and environmental pollution. This condition has encouraged the adoption of the Sustainable Agriculture concept, which emphasizes a balance between ecological, economic, and social aspects. Its successful implementation is strongly influenced by farmers’ perceptions as the main actors. This study aims to analyze rice farmers’ perceptions of the implementation of Sustainable Agriculture in swampy areas of Tebas District, Sambas Regency. The research was conducted from October to November 2025 using a survey method involving 95 farmers selected through the Slovin formula and proportional random sampling technique. Data were collected through observation, interviews, and Likert-scale questionnaires, and analyzed using descriptive analysis and binary logistic regression. The results show that farmers’ perceptions are generally positive, particularly regarding water management, variety selection, and cropping patterns. However, the use of organic fertilizers, environmentally friendly pest control, and post-harvest management are still considered difficult. Education level and non-farming occupations significantly influence farmers’ perceptions. Therefore, enhancing extension services, training, and support for business diversification is necessary to promote the adoption of Sustainable Agriculture.

Oil palm is a leading commodity that makes a major contribution to Indonesia’s economy, yet a significant productivity gap remains between actual and potential yields. A principal cause is suboptimal water management, which leads to flooding during the rainy season and drought in the dry season. This study develops a Conceptual Design (CD) for water management to map existing problems, analyse root causes, formulate improvement measures, and present a macro-level cost estimate for the study site. The research was conducted at an oil palm plantation in East Kalimantan anonymized as “PT XYZ.” The site was selected due to recurrent flooding and a recent change in ownership that limited data availability, making it well-suited for a CD-stage assessment. The objective is to identify water management issues and propose effective recommendations. A quantitative approach integrates primary data from field observations and measurements with secondary data. The analyses cover flood problem assessment, Water Management Zoning (WMZ/ZPA), rainfall analysis, hydrology, hydraulics, improvement proposals, and macro cost estimation. Results indicate that challenges are driven by swampy land conditions and inadequate channel and hydraulic structure capacity. Micro-watershed delineation using DEMNAS identified four ZPAs totalling 479–4,061 ha. Design rainfall was derived from CHIRPS satellite data using a log-normal distribution. Hydrologically, peak discharges range from 3.87–22.58 m³/s for the 2-year return period and 4.46–26.31 m³/s for the 5-year return period. Hydraulically, the proposed dimensions for rivers, outlet drains, carrier drains, and field-edge drains are 4×3×2 m to 9×7×3 m (T=2 years) and 4×3×2 m to 10×8×3 m (T=5 years), while collection and main drains are proposed at 3×2×2 m for both return periods. The total estimated investment for the 5-year design scenario is IDR 27,999,263,000.

The pitcher plant (Nepenthes sp.) is a type of predatory plant typically found in tropical regions and has a pitcher structure designed to attack insects. The pitcher's structure acts as a small ecosystem that supports a variety of microorganisms, both those living on the surface (epiphytes) and those within the tissue (endophytes). This study aimed to extract and identify microorganisms present on the surface and interior of the pitcher plant. Samples were taken from peat swamps and separated using Nutrient Agar (NA) for bacteria and Potato Dextrose Agar (PDA) for fungi. The discovery process involved examining morphological characteristics both visually and under a microscope. The results revealed differences in the types of microorganisms between the outside and inside of the pitcher, influenced by the microenvironmental conditions in each area. These findings can serve as a foundation for further study of the bioactive potential of microorganisms from the pitcher plant.

The Community-Based Sanitation Program (PAMSIMAS) is a government initiative aimed at improving community access to proper sanitation facilities, particularly in rural areas. This study aims to evaluate the effectiveness of the program in Tanjung Aman Village, Wampu District, Langkat Regency. A qualitative approach was used with a phenomenological method, focusing on the experiences and perceptions of local residents and village officials regarding program implementation. Data were collected through in-depth interviews, field observations, and documentation, involving 15 informants comprising residents, sanitation cadres, and village officials. The findings show that technically, the sanitation facilities function well; however, sustainability in usage faces challenges such as low community participation, weak maintenance systems, and the absence of binding local regulations. Community perception of the program is generally positive, particularly regarding improvements in environmental cleanliness and comfort in using the facilities, yet unequal access remains a significant issue. The study concludes that the success of PAMSIMAS largely depends on collaboration among the community, local cadres, and village policies. Strategic recommendations include the formulation of Village Regulations, regular training for cadres, and the establishment of a community-based sanitation management institution. With this approach, the program is expected to operate sustainably and provide long-term benefits to rural communities.

Mutiara Serpong Villa Complex, located in Pondok Jagung Timur Village, South Tangerang, is surrounded by the BSD City area. This area faces environmental problems due to the uncontrolled growth of water hyacinth (Eichornia Crassipes) in the surrounding lakes and swamps, causing irrigation disruption and decreasing water quality. Water hyacinth is known as a weed that damages the aquatic environment, but it also has positive potential as a raw material for organic fertilizer. This program aims to overcome the problem of the spread of water hyacinth by utilizing the plant into organic compost. Water hyacinth compost contains high nutrients, helps improve soil properties, and improves the quality and quantity of plants. This initiative is expected to provide environmental benefits while increasing the income of the surrounding community through the use of water hyacinth as organic fertilizer. Community Service Activities at the Mutiara Serpong Villa Complex use several methods that aim to provide understanding and skills about making compost from water hyacinth to the local community. There are five main stages: Socialization, Counseling, Training and Practice, Observation and Evaluation, Sustainability. This method is designed to increase active community participation and the sustainability of water hyacinth compost use as a beneficial environmental solution.

The recruitment of new mechanics at Mataram Sakti is no longer through the training process at the head office, but new mechanics are placed at the dealership accompanied by the chief mechanic as a supervisor, with the aim of providing training to new mechanics in order to be able to service or periodically repair Yamaha products especially the latest motorbikes namely Yamaha NMAX, because of the flurry sometimes the mechanical head is not in place so that when the mechanic is experiencing problems it cannot directly ask the mechanical head causing the handling of repairs to be less effective and efficient. One way to overcome this is to create a web-based expert system application with a forward chaining method so that the chief mechanic can transfer the knowledge he has into the computer. Forward chaining method is a search technique that starts with known facts and then matches these facts with the IF part of the IF-Then rules, so that conclusions can be drawn. This expert system was built using supporting software including, Macromedia Dreamweaver MX, PHP script language, MySQL database and WAMP server. The expert system for diagnosing damage to Yamaha NMAX motorcycles using the forward chaining method can be used as a new mechanical learning media in diagnosing damage to NMAX motorcycles and as a means of chief mechanics transferring their knowledge.
