To reduce dependence on petroleum fuels, one way is to produce biodiesel fuel whose raw materials are obtained from plants. Biodiesel is a fuel that contains ester compounds from plants and animal fats and can be used as an alternative fuel with great potential as a substitute for diesel. This form of methyl ester or ethyl ester compound is environmentally friendly, non-toxic and economical. Coconut (Cocos nucifera) is a type of plant that has one glycerin unit and a number of fatty acids in every coconut oil molecule. Coconut oil has the potential to produce Coco methyl ester which can be used as a raw material for biodiesel. Used cooking oil is used oil from household (domestic) fryers whose remaining frying results or waste is immediately thrown into the environment. According to research from Kumar, the use of coconut oil as a raw material for making biodiesel is able to streamline time and the use of chemicals as solvents in the transesterification process. Before carrying out this research, a preliminary test should be carried out, by testing the %FFA, pH and density of the mixture of used cooking oil and coconut oil. This was done as a reference for further research. The %FFA in the mixture of used cooking oil and coconut oil was the highest at a ratio of 75: 25 (MJ: MK) %FFA value: 4.4%. The pH of the mixture between used cooking oil and coconut oil has the same value, namely: 5 and the specific gravity obtained is: 0.8 gram/ml \u0000 \u0000Keywords: of used cooking oil, coconut oil, % FFA, pH and Specific gravity","PeriodicalId":517097,"journal":{"name":"JURNAL TEKNOSAINS KODEPENA","volume":"196 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140475208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dalam pembuatan biodiesel dari minyak goreng bekas, diperlukan kualitas minyak goreng dengan angka asam kurang dari 1%. Salah satu cara untuk menurukan angka asam adalah dengan proses adsorbsi menggunakan arang aktif. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh adsorbsi minyak jelantah dengan menggunakan kulit pisang kepok pada pembuatan biodiesel dari minyak goreng bekas, dan untuk mengetahui karakteristik biodiesel yaitu angka asam, titik nyala, massa jenis, viskositas dan gliserol bebas dari biodiesel yang dihasilkan dengan bahan dasar minyak goreng bekas yang dibuat dengan proses transesterifikasi dengan proses adsorbsi arang aktif kulit pisang kapok terlebih dahulu. Pemanfaatan minyak goreng bekas sebagai bahan dasar untuk membuat biodiesel berhasil dilakukan. Minyak goreng bekas yang akan dimanfaatkan sebagai bahan dasar biodiesel sebelumnya dilakuka pra – treatment berupa proses adsorbsi menggunakan arang aktif kulit pisang kapok. Semakin lama waktu yang digunakan untuk proses adsorbsi minyak goreng bekas menggunakan arang aktif akan semakin baik hasilnya. Karakteristik biodiesel yang terbaik dari penelitian ini di dapatkan dari proses adsorbsi selama 2 jam dengan titik nyala 162°C, angka asam 2,288 mg KOH/gram, massa jenis 830 kg/m³ dan viskositas 6,76 cSt. \u0000Keywords: Biodiesel, adsorbsi, arang aktif, penggunaan minyak goreng","PeriodicalId":517097,"journal":{"name":"JURNAL TEKNOSAINS KODEPENA","volume":"28 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140474815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
