Biodiesel, which is generally defined as monoalkyl esters from plant and animal fats, is an alternative fuel that has the potential to be used as a substitute for diesel fuel because of its characteristics. Used cooking oil or used cooking oil haD the potential to be processed into biodiesel and this study aims was to produce waste cooking oil into biodiesel from the results of the pre-treatment process of used cooking oil with bagasse waste, to find out the optimum result of the oil pretreatment proces and the raw material used was used cooking oil from the Rocket Chicken Food Court restaurant. Waste from sugarcane bagasse was useful as an adsorption process for the purification of used cooking oil which was able to reduce free fatty acid levels, water content, and impurities levels for the biodiesel process. The optimum particle size of bagasse waste for used cooking oil pretreatment was 30 mesh, with the analytical data was 1.93%  of free fatty acid, 0,0018 % for water content and 0,03% of firt level. The results of the Biodiesel analysis from the pre-treatment process were the viscosity was 5.7 Cst, the density was 860 kg/m3 and the acid number was 0.8 mg KOH/g oil. This result was accordance to the indonesian national standard No. 04-7182-2006.

This Community Service activity aims to optimize the use of environmentally friendly agricultural products in the home industry for processing aloe vera into nata de aloevera. The agricultural products used are rice straw waste and bagasse which are processed into biodegradable raw materials. The experiment was carried out using a completely randomized design (CRD) with three treatments namely A (50% waste rice straw + 50% bagasse), B (75% waste rice straw + 25% bagasse), and C (25% waste rice straw + 75% bagasse). Measurements were made of the parameters pH, total acid, water content, protein content, and organoleptic nata de aloevera. The results showed that treatment A gave the best results in terms of pH, total acid, and protein content. Meanwhile, C treatment gave the best results on water content and organoleptic. It is hoped that the results of this research can provide alternatives to the use of environmentally friendly raw materials in the home industry for processing aloe vera into nata de aloevera and can meet consumer needs for healthy and safe food products..  Keywords: Biodegradable agricultural products, Home industry, Aloe vera processing, Nata de aloevera, Green technology, Green technology   Abstrak_Indo. Kegiatan Pengabdian pada Masyarakat ini bertujuan untuk mengoptimalkan pemanfaatan produk pertanian yang ramah lingkungan pada home industry pengolahan aloe vera menjadi nata de aloevera. Produk pertanian yang digunakan adalah limbah jerami padi dan ampas tebu yang diolah menjadi bahan baku biodegradable. Percobaan dilakukan dengan menggunakan rancangan acak lengkap (RAL) dengan tiga perlakuan yaitu A (50% limbah jerami padi + 50% ampas tebu), B (75% limbah jerami padi + 25% ampas tebu), dan C (25% limbah jerami padi + 75% ampas tebu). Pengukuran dilakukan terhadap parameter pH, total asam, kadar air, kadar protein, dan organoleptik nata de aloevera. Hasil penelitian menunjukkan bahwa perlakuan A memberikan hasil terbaik pada parameter pH, total asam, dan kadar protein. Sementara itu, perlakuan C memberikan hasil terbaik pada kadar air dan organoleptik. Diharapkan hasil dari penelitian ini dapat memberikan alternatif pemanfaatan bahan baku yang ramah lingkungan dalam home industry pengolahan aloe vera menjadi nata de aloevera serta dapat memenuhi kebutuhan konsumen pada produk makanan yang sehat dan aman.
