Abstract
Biodiesel is an alternative fuel from renewable sources derived from vegetable oils through the process of transesterification or esterification. Based on the feasibility test results of several raw materials, waste cooking oil is suitable as an alternative to vegetable oil in making biodiesel. Bentonite is used in the process of making biodiesel as a heterogeneous catalyst because it has the characteristic of being easily separated from the product. The purpose of this research is to determine the optimum conditions for making biodiesel with bentonite catalysts, determine the quality of biodiesel products from waste cooking oil by testing physical properties and chemical properties, and obtain biodiesel. This study was conducted by impregnating bentonite with KOH with variations in the number of grams of KOH / 100 ml aquades, namely 27 and 32 grams KOH / 100 ml aquades at 60°C for 2 hours and calcining at 400°C for 5 hours. The transesterification method is carried out to produce biodiesel with temperature variations at temperatures of 50, 60, 65°C during a reaction time of 3 hours and a molar ratio of methanol and waste cooking oil of 1:6 with a catalyst concentration of 4%. This research obtain optimum operating conditions at bentonite catalyst concentration 32% KOH, catalyst percentage 4%, methanol molar ratio 1:6 reaction temperature 65°C, produced, density, viscosity, yield, flash point, and %FAME respectively 856 kg/m3; 2.34 cSt ; 95.69% ; 132°C and 99.88%. The catalyst can be used repeatedly up to 3x usage.

| Additional Information: | Biodiesel merupakan bahan bakar alternatif dari sumber terbarukan yang berasal dari minyak nabati melalui proses transesterifikasi atau esterifikasi. Berdasarkan hasil uji kelayakan beberapa bahan baku, minyak jelantah layak dijadikan sebagai alternatif minyak nabati pada pembuatan biodiesel. Bentonit digunakan pada proses pembuatan biodiesel sebagai katalis heterogen karena mempunyai karakteristik mudah dipisahkan dari produknya. Tujuan dilakukannya penelitian ini adalah mengetahui kondisi optimum pada pembuatan biodiesel dengan katalis bentonit, mengetahui kualitas produk biodiesel dari minyak jelantah dengan pengujian sifat fisik dan sifat kimia, dan mendapatkan biodiesel. Penelitian ini dilakukan dengan mengimpregnasi bentonit dengan KOH dengan variasi jumlah perbandingan gram KOH/100 ml aquades yaitu 27 dan 32 gram KOH/100ml aquades pada suhu 60 °C selama 2 jam dan kalsinasi pada suhu 400 °C selama 5 jam. Metode transesterifikasi dilakukan untuk menghasilkan biodiesel dengan variasi temperatur pada suhu 50, 60, 65 °C selama waktu reaksi 3 jam dan rasio molar metanol dan minyak jelantah 6:1 dengan konsentrasi katalis 4%. Didapatkan kondisi operasi optimum pada konsentrasi katalis bentonit 32% KOH, persentase katalis 4%, rasio molar metanol 1:6 suhu reaksi 65℃, dihasilkan, densitas, viskositas, yield, flash point, dan %FAME berturut-turut 856 kg/m3 ; 2,34 cSt ; 95.69% ; 132oC dan 99.88%. Katalis dapat digunakan berulang kali hingga 3x pemakaian. | ||||||
