“…G 0 is the product of the total fatty acid equivalent (mgrek/gr) by the weight of the oil (gr). [9] Determination of total fatty acid equivalent (EALT) Glycerol esterified as much as 5gr was put into Erlenmeyer then added 50 ml of 0.5 N NaOH and then heated for 30 minutes. Furthermore, after being cooled this solution was added 3 drops of pp indicator and titrated with 0.5 N HCl solution until the color changed to clear.…”

Transesterification of oil with alcohol produces glycerol and methyl esters (biodiesel). The reaction is influenced, among others, by the amount of catalyst and the ratio of oil and meth hanol reagents. This purpose of research to determine the effect of the amount of catalyst and the ratio of reagents on the conversion of glycerol. The experiment was carried out in a three-necked flask equipped with a stirrer and reverse cooling. In a three-necked flask, 150 ml of castor oil was added, 0.375 ml of H2SO4 was added, heated to a temperature of 650C. Then add 185 ml of methanol and stir for 30 minutes. Then let stand 24 hours to form two layers. The bottom layer is glycerol. The transesterification process was continued by adding 100 ml of glycerol in a mixture of methanol (variation 1:2, 1:3, 1:4) with RCC catalyst (variation 1.7gr;1.9gr;2.1gr;2.3gr ;2.5gr) The mixture was then stirred at 90 rpm for 75 minutes. Based on the results of research conducted, the highest glycerol conversion value was in the amount of catalyst 2.1 g with a ratio of reagents between castor oil and methanol of 1:3 of 55.33%.

Used cooking oil is widely considered waste because it can damage the environment and cause health problems. Meanwhile, used cooking oil can be used as a substitute raw material for Crude Palm Oil (CPO) in Indonesia's national biodiesel program.Indonesia has a remarkable ability to use used cooking oil as a raw material for making biodiesel. If the 1.2 million kiloliters of biodiesel made from CPO raw materials are exchanged with used cooking oil raw materials, it can save approximately Rp.4.2 trillion. There are various process technologies in making biodiesel, including microemulsion, pyrolysis, and transesterification. Transesterification is a process in which triglycerides and methanol are reacted to create biodiesel and glycerol as a by-product. Transesterification using a homogeneous catalyst has advantages such as lower cost, relatively short processing time, and higher yield of biodiesel products.Transesterification using a homogeneous catalyst has the disadvantage of a more complex separation. This literature study aims to explain the method for biodiesel production and becomes a reference in terms of process selection in biodiesel manufacturing plants, especially from used cooking oil as raw material.

Eksploitasi bahan bakar fosil yang dilakukan secara terus-menerus menyebabkan jumlahnya semakin menipis. Pemerintah memberikan solusi untuk mengatasi permasalahan tersebut melalui penggunaan bahan bakar alternatif seperti biodiesel. Penggunaan katalis dalam proses produksi biodiesel sangat disarankan. Katalis heterogen berbasis kalsium hasil dekomposisi CaCO3 pada cangkang hewan telah diteliti dapat digunakan sebagai katalis dalam reaksi transesterifikasi. Pada penelitian ini dilakukan dekomposisi CaCO3 menjadi CaO dari cangkang telur bebek yang dilakukan dengan kalsinasi pada temperatur 900°C selama 4 jam. CaO yang dihasilkan diaplikasikan dalam reaksi transesterifikasi dengan variasi konsentrasi katalis 1, 2, 3 dan 4%, rasio mol minyak:metanol 1:9, temperatur reaksi 63°C, dan waktu reaksi 3 jam. Berdasarkan difraktogram, kalsinasi cangkang telur bebek pada 900°C telah mengkonversi CaCO3 menjadi CaO. Puncak-puncak utama CaO muncul pada °2θ 32,24; 37,41; 53,93; 64,24; 67,47 dan 91,60 sesuai dengan data standar CaO ICDD No. 01-070-4068. Adapun yield metil ester yang dihasilkan pada setiap konsentrasi katalis yaitu 82,45%, 85,93%, 93,01% dan 78,48%. Metil ester dengan yield tertinggi (katalis 3%) dianalisis menggunakan GC-MS, berdasarkan analisa GC, terdapat 6 puncak dan berdasarkan spektrum massa teridentifikasi senyawa metil kaprat, metil laurat, metil miristat, metil palmitat, metil oleat dan metil stearat. Metil ester memiliki densitas 860,48 kg/m3 ; viskositas 5,8 mm2 /s; angka setana 59; dan residu karbon 0,34%.
