This study aims to examine the effectiveness of attractants on the activity of the pollinating beetle Elaeidobius kamerunicus and its impact on the efficiency of pollination and palm oil (Elaeis guineensis) production at PT Menthobi Makmur Lestari, Lamandau Regency, Central Kalimantan. The study was conducted from May to July 2025 using a factorial randomized block design with two factors: topography (flat 0–8% and hilly 15–25%) and attractant doses (0, 1, 2, and 3 ml/ha) with three replications.The parameters observed included the frequency of E. kamerunicus visits to female flowers and the percentage of fruit set. The results showed that the topography factor, attractant dose, and their interaction significantly affected the number of E. kamerunicus visits and fruit set (p < 0.01). The combination of flat land with high attractant doses resulted in the highest visits (69.04 beetles/spike) and maximum fruit set (75.11%), while the hilly land without attractants showed the lowest results (34.60 beetles/spike; 61.22%). The application of attractants increased fruit set by more than 20% compared to the control, leading to an increase in bunch weight (BJR) of approximately 5.67 kg/bunch, additional production of about 1,151 kg FFB/ha per 1.5 months, and a potential income of Rp 3,683,200/ha, far exceeding the application cost of Rp 211,638/ha. These results indicate that the use of attractants is an effective and efficient agronomic strategy to improve palm oil productivity. Thus, attractants have proven to significantly enhance pollination efficiency and palm oil production, providing substantial economic benefits to farmers and supporting the sustainability of palm oil plantations. This approach offers an applicable and sustainable solution for agricultural practices, which can be applied to various locations with similar topographical conditions.  

Kebonagung hamlet in Sukolelo village is an area where the majority of residents cultivate bananas. The abundant banana production generates a considerable amount of waste, one of which is banana stems that are usually piled up, burned, or left to rot without further use. Therefore, this community service project aims to provide a comprehensive overview of the potential use of banana waste as raw material for organic compost in Kebonagung Hamlet, Sukolelo Village. The methods used in this study involved banana farmers as research subjects and banana stems as research objects, with data collection techniques including field observations, interviews with farmers, and composting experiments.

Testing was carried out on several diagnostic scenarios to evaluate the accuracy and efficiency of the system. The results of the study indicate that the expert system can provide an initial diagnosis quickly and accurately, producing outputs consistent with expert assessments. This functionality assists farmers in making timely decisions regarding appropriate medical interventions, thereby reducing treatment delays and minimizing the risk of disease transmission within the herd. Consequently, the Forward Chaining-based expert system is expected to serve as an innovative solution to improve dairy cattle health management and support sustainable livestock productivity at Cibugary Farm.

This study examines two main issues related to palm oil trading transactions in Kuala Keritang Village, Indragiri Hilir Regency, Riau Province. The first issue concerns the analysis of pricing mechanisms in palm oil trading, while the second focuses on the review of Islamic business ethics in such transactions. The objective of this research is to understand in detail how the price determination system operates in the local palm oil market and to assess the extent to which these trading practices align with the principles of Islamic business ethics. To address these issues, a qualitative descriptive method was employed. This approach was chosen because it allows for a comprehensive description of facts, data, and trading mechanisms while providing space for critical analysis in relation to Islamic values. Data were obtained through observation, interviews, and documentation, which were then described, analyzed, and discussed in order to answer the research questions thoroughly. The findings indicate that, in general, palm oil trading practices in Kuala Keritang Village are similar to other common trading systems, but they differ in terms of price-setting mechanisms. In practice, the price of palm oil is largely determined by buyers based on market conditions, which often creates injustice for farmers as sellers. From the perspective of Islamic business ethics, this practice does not fully comply with the principles of fairness, honesty, and mutual benefit, which are essential foundations of Islamic economic transactions. The study concludes that violations of Islamic business ethics principles, particularly regarding fairness in pricing, still occur in palm oil trading within the village. Therefore, improvements are needed in the transaction system so that palm oil trading in Kuala Keritang can be carried out in accordance with sharia principles, ensuring justice and mutual benefit for both sellers and buyers.
