Abstract

Mita Sani Jaya merupakan salah satu agen yang bergerak dibidang distribusi gas LPG 3 kg kepada pangkalan. Proses pengiriman gas LPG 3 kg dilakukan dari hari Senin hingga Sabtu ke 55 pangkalan, berdasarkan studi pendahuluan terhadap proses pengiriman gas LPG 3 kg ditemukan permasalahan yaitu waktu tempuh pengiriman cukup panjang serta sarana pengangkut dan kapasitas yang terbatas. Selama ini agen belum merancang rute dan jadwal pengiriman gas LPG 3 kg dari pangkalan satu ke pangkalan lainnya dengan pemlihan rute dan penjadwalan yang konsisten dan optimal. Penelitian ini bertujuan untuk menentukan rute dan penjadwalan pengiriman gas LPG 3 kg di PT. Mita Sani Jaya sehingga waktu tempuh yang optimal, algoritma Clarke and Wright Savings digunakan untuk meminimumkan waktu tempuh dengan mempetimbangkan kapasitas kendaraan. Berdasarkan hasil perhitungan penjadwalan dengan menggunakan software LINDO 6.1, Maka diperoleh penghematan waktu tempuh pengiriman tabung gas LPG 3 kg PT.Mita Sani Jaya pada hari pertama sebesar 64 menit, hari kedua 111 menit, hari ketiga 92 menit hari ke empat 80 menit, hari ke lima 57 menit dan hari ke enam sebesar 54 menit. Hal ini menunjukan bahwa algoritma Clarke and Wright Savings dengan bantuan software LINDO 6.1 dapat mengurangi waktu tempuh pengiriman. Kata kunci : pendistribusian gas LPG 3 kg, waktu tempuh, penentuan rute dan penjadwalan.

Abstract

The lack of knowledge and skills among the community, particularly the Mekar Jaya group in Seruway village, has resulted in the limited utilization of tofu dregs waste, which is primarily used as supplementary livestock feed. In fact, tofu dregs still contain sufficient nutrients to be used as a formulation ingredient for making floating fish pellets. The Mekar Jaya group already possesses village assets such as fish breeding ponds and fish pellet production machines, but fish farmers are still purchasing fish pellets for their fish farming. This community service activity aims to train fish farmers to process tofu dregs waste into fish pellet formulations, as well as to conduct hands-on training in producing floating fish pellets using the fish pellet machine. The method applied in this community service activity involves a structured training approach. Overall, the results of the community service activity show positive achievements. The Mekar Jaya farmer group has demonstrated independence in preparing floating fish feed formulations. They have also shown innovation and creativity in making floating feed and have begun independently producing the floating fish feed they learned through this training. The impact can be seen in the increased enthusiasm and motivation of the farming group in participating in the training provided
