Abstract

produksi biodiesel. CaO diperlukan sebagai katalis untuk reaksi transesterifikasi. penelitian ini, katalis CaO dihasilkan dari kalsinasi limbah cangkang Bekicot (Achatina fulica) pada suhu o C selama 10 jam. Kalsinasi pada suhu tinggi digunakan untuk merubah senyawa CaCO 3 menjadi senyawa CaO. Produksi biodiesel menggunakan katalis CaO dilakukan pada rasio mol minyak: metanol 1:6, 3 g berat katalis, suhu reaksi 60 °C, waktu reaksi 3.5 jam dan kecepatan 250 rpm dengan hasil biodiesel yang diperoleh terdiri dari 100% metil ester. Abstract The transesterification reaction is a reaction used for biodiesel production. CaO is needed as a catalyst for the transesterification reaction. In this study, the CaO catalyst was produced from calcining the shell of the Snail (Achatina fulica) at a temperature of 900 o C for 10 hours. Calcination at high temperature is used to convert CaCO 3 compounds into CaO compounds. Biodiesel production using CaO catalyst on the mole ratio of oil: methanol 1:6, the reaction time of 3.5 hours, 3 g weight of catalyst, the reaction temperature at 60 °C, and stirring speed of 250 rpm with biodiesel results obtained at 100% metil ester.
