Pesidi Village, located in Grabag Subdistrict, Magelang Regency, is a highland region with promising potential in agriculture and livestock, particularly sheep farming. However, one of the major challenges faced by local farmers is the limited availability of forage during the dry season, coupled with the low utilization of agricultural by-products such as rice straw. These constraints often hinder livestock productivity and pose risks to feed security. To address this issue, a community service program was conducted with the aim of introducing and demonstrating local-based feed processing technologies, including silage, ammoniation, and Urea Mineral Block (UMB) production. The activity was implemented in several stages: problem identification, socialization, education, training, and monitoring of farmer implementation. Through this participatory approach, farmers were given hands-on training and practical guidance on processing alternative feed sources to ensure the availability of nutritious and sustainable livestock feed. The results showed that farmers began adopting UMB as a feed supplement due to its practicality and visible benefits in maintaining livestock health and productivity. However, silage and ammoniation methods were not yet widely adopted, mainly due to limited experience, lack of supporting equipment, and the perception that the processes were relatively complex. Despite these challenges, the program succeeded in raising farmer awareness of the importance of feed diversification and the optimization of agricultural waste. The training provided valuable insights into how the integration of silage, ammoniation, and UMB can increase feed efficiency, reduce dependency on fresh forage, and support sustainable livestock management. The implementation of these three technologies holds significant potential to enhance sheep farming productivity in rural highland communities, while simultaneously strengthening food security and supporting environmentally friendly agricultural practices.

The development of information technology has driven changes in society’s transaction patterns, one of which is online transactions. Although electronic payment systems are increasingly common, the Cash on Delivery (COD) method remains popular due to its perceived safety and practicality. However, this method also raises legal issues, particularly concerning consumer protection and dispute resolution. This study aims to examine online transactions and COD payments based on the Indonesian Civil Code (KUH Perdata), as well as to analyze the dispute resolution procedures that may arise. The research method used is normative legal research with a statutory and conceptual approach. The results show that COD transactions constitute valid agreements if they meet the conditions outlined in Article 1320 of the Civil Code. However, in practice, cases of breach of contract and unlawful acts are still frequently found. Dispute resolution may be pursued through court litigation or alternative dispute resolution (ADR). In conclusion, legal protection for consumers in COD transactions needs to be strengthened through clearer and more specific regulations to ensure consumer rights remain protected.
