Abstract

Biodiesel merupakan energi terbarukan yang berasal dari minyak nabati atau minyak hewani. Pada penelitian ini pembuatan biodiesel dilakukan dengan metode ekstaksi reaktif (transesterifikasi insitu). Bahan baku yang digunakan yaitu ampas perasan kelapa dengan bilangan asam 0,5426 mg KOH/g, diameter partikel sebesar 1,12 mm. Katalis yang digunakan yaitu KOH 2%b/b pro analisis sedangkan metanol atau etanol teknis sebagai pereaksi. Transesterifikasi in situ ampas kelapa dilakukan pada temperatur reaksi 65°C dan kecepatan pengadukan 1000 rpm. Variasi variabel adalah waktu reaksi 4,5,6,7,8,9 jam dan jenis pereaksi yaitu metanol dan etanol teknis. Hasil penelitian ini menunjukan bahwa waktu reaksi dan jenis pereaksi berpengaruh terhadap yield biodiesel. Hasil penelitian menunjukan penggunaan metanol sebagai reaktan menghasilkan yield sebesar 85,97 % sedangkan etanol sebesar 53,57 %. Yield biodiesel 85,97% dengan reaktan metanol dicapai selama 8 jam. Hasil analisis biodiesel tersebut menunjukan bahwa nilai densitas, kadar air, viskositas memenuhi standar SNI Biodiesel No.7182-2012 sedangkan untuk gliserol total, dan bebas tidak memenuhi SNI.

Abstract

The average consumption rate of cooking oil in Indonesia on 2019 was 61 million litre. Because of that makes the waste cooking oil produces very high to. To prevent the consument littering the waste cooking oil, we can recycle it to be biofuel with many fraction such as biodiesel, biogasoline, and biokerosene. There are many ways to process the waste cooking oil to be, biofuel one of them is catalytic cracking. This study is induct by observe the biofuel that form from the catalytic cracking process with cooking oil as the base material using a hybrid catalyst ZSM-5/Alumina. The purpose of this study is to observe the influence of ZSM-5 and Alumina ratio as heterogenic catalyst and also the used of the catalyst frequently. The highest conversion of liquid product was produce with value 41,67% at alumina variation of 17,5%. The used of catalyst frequently will affect the decrease amount of liquid product that produce. The analysis of chemical properties using GC-MS obtained the amount of kerosene 29,917 %; gasoline 3,996 %; and diesel 10,1 %. The other product was carboxylics acids,alcohol, and unidentified compound. Keyword : Cooking oil, biofuel, ZSM-5, Alumina, catalytic cracking
