Abstract

Biodiesel is an alternative fuel produced from vegetable oils such as soybean oil by the method of transesterification with the help of catalysts. This research uses a heterogeneous catalyst, CaO which is derived from an eggshell through a calcination process is impregnated with NaOH so that the CaO cavity can be filled by Na ions in order to increase the alkaline nature of the catalyst. The increase in biodiesel yield can be done by varying the catalyst concentration of CaO/NaOH and mole ratio of soybean oil / methanol. CaO catalyst obtained from calcination of chicken eggshell was impregnated with 5% NaOH (w/v) as much as 50 ml into 50 g of CaO gradually, stirred while accompanied by heating, and continued calcination at 300 ℃ for 3 hours. Biodiesel synthesis was carried out by esterification and transesterification using methanol, biodiesel synthesis was done by varying the mole ratio of soybean oil with methanol 1: 6; 1: 9; 1:12 and catalyst concentration 0.5; 1 and 1.5% at 60-65°C for 3 hours. The best result was obtained with a yield of 86.7860% in the mole ratio of oil with methanol 1:12 with a catalyst concentration of 1% based on oil weight, density of 0.8899 gram / ml, viscosity of 3.5208 Cst, acid number of 0.33 mg KOH/g max and water content of 0.0095% and this is in accordance with SNI 7182: 2015 standards.

Abstract

Produksi minyak bumi mengalami penurunan, dari 346 juta barel pada tahun 2009 menjadi sekitar 283 juta barel di tahun 2018. Biodiesel mulai berkembang seiring adanya pelaksanaan kebijakan mandatori yang mengamanatkan campuran bahan bakar nabati ke bahan bakar minyak sebesar 20% (B20). Minyak jelantah sangat berpeluang untuk dijadikan sebagai bahan baku dalam pembuatan biodiesel karena mengandung trigliserida. Tujuan penelitian ini adalah mengetahui pengaruh jumlah katalis dan rasio massa metanol:minyak terhadap rendemen, densitas, viskositas kinematik, kadar air dan bilangan asam biodiesel. CaO dibuat dengan mengkalsinasi cangkang telur pada suhu 900oC selama 3 jam. CaO diberi C sebagai support dengan perbandingan CaO:C yaitu 1:1 kemudian diimpregnasi dengan  NaOH 35%. Setelah itu dikalsinasi pada suhu 800oC selama 3 jam. Pembuatan biodiesel dilakukan pada suhu 60oC selama 3 jam dengan memvariasikan jumlah katalis 4,5%, 5,5%, 6,5%, 7,5% dan rasio massa metanol:minyak jelantah 0,25:1, 0,5:1, 0,75:1. Hasil biodiesel terbaik diperoleh pada variasi jumlah katalis 4,5% dengan rasio massa metanol:minyak jelantah 0,5:1 dengan hasil rendemen 84,2610%, densitas 0,8652 gr/ml, viskositas kinematik 2,5900 cSt, kadar air 0,0279% dan bilangan asam 0,3375 mgNaOH/gr.
