Abstract. Environmental problems in Muara Village, Suranenggala Subdistrict,Cirebon Regency, are accumulated waste of green mussel shells. The objectives ofthis PKM activity are: 1) to deal with the accumulation of green mussel shells asfeed ingredients / fish pelets by applying technology, namely; hammer millmachines, mixer machines, pelet extruders, and 2) to improve the welfare of thecommunity from the activities of making fish feed / pelets. The method used isParticiparoty Action Rural (PRA) which is one of the Participaroty Action Researchmethods. This method prioritizes community participation, identifying problems,compiling programs to plan solutions together. The location of the activity wascarried out in the fishermen group in Muara Village, Suranenggala District,Cirebon Regency. The results of the application of technology for the process ofmaking animal feed carried out in Muara Village can create new businesses forcommunity groups, especially fishermen groups, so that it has implications forincreasing welfare for the surrounding community. Based on the results ofmonitoring and evaluation, it is concluded that the application of appropriatetechnology in overcoming the accumulation of green mussel shell waste can create anew business, namely UKM making fish feed / pelets which in turn can improvewelfare for the community.Keywords: SMEs, appropriate technologyAbstrak. Permasalahan lingkungan di Desa Muara Kecamatan SuranenggalaKabupaten Cirebon adalah menumpuknya limbah cangkang kerang hijau. Tujuandari kegiatan PKM ini adalah 1) untuk menanggulangi menumpuknya limbahcangkang kerang hijau sebagai bahan pakan/pelet ikan dengan penerapanteknologi, yaitu mesin hammer mill, mesin mixer, pelet extruder; dan 2) untukmeningkatkan kesejahteraan masyarakat dari kegiatan pembuatan pakan/pelet ikan.Metode yang digunakan adalah Participaroty Action Research (PAR). Metode inimengutamakan partisipasi masyarakat, mengidentifikasi masalah, dan menyusunprogram merencanakan solusi bersama-sama. Lokasi kegiatan dilaksanakan padakelompok nelayan di Desa Muara, Kecamatan Suranenggala, Kabupaten Cirebon.Hasil dari penerapan teknologi untuk proses pembuatan pakan ternak yangdilakukan di Desa Muara dapat memunculkan usaha baru bagi kelompokmasyarakat, khususnya kelompok nelayan sehingga dapat berimplikasi terhadapmeingkatnya kesejahteraan bagi masyarakat sekitar. Berdasarkan hasil monitoringdan evaluasi disimpulkan bahwa penerapan teknologi tepat guna dalammenanggulangi menumpuknya limbah cangkang kerang hijau dapat menciptakanusaha baru, yaitu UKM pembuatan pakan/pelet ikan yang pada akhirnya dapatmeningkatkan kesejahteraan bagi masyarakat.Kata Kunci: UKM, Teknologi tepat guna

This research is focused on the effect of processing parameters such as molar ratio of sample to solvent (1:3-1:15), catalyst loading (0.5-2.5 wt %), temperature (40-80 °C) and time of reaction (5-180 min) on the transesterification yield of waste cooking oil (WCO) in conventional thermal heating and microwave heating techniques. The analysis carried out revealed that the microwave assisted transesterification produced a comparable yield to conventional heating transesterification with ~5 times faster in heating up the reaction mixture to a reaction temperature and reduced ~90% of the reaction time required. This study concludes that microwave assisted transesterification, which is a green technology, may have great potential in reducing the processing time compared to conventional thermal heating transesterification.
