Abstract

Telah dilakukan penelitan pengaruh pemakaian minyak jelantah 6, 8 dan 10 kali pemakaian terhadap % rendemen pembentukan metil ester (biodiesel ) menggunakan katais basa homogen NaOH 0,6% massa. Seluruh sampel minyak jelantah direaksikan dengan methanol dengan perbandingan reaktan 1:5 % massa. Reaksi transesterrifkasi masing-masing sampel dilakukan pada suhu 60°C selama 40 menit. Hasil rendemen sampel minyak jelantah 6 kali pemakaian sebesar 96,6%, sedangkan 8 dan 10 kali pemakian menunjukkan nilai yang tidak jauh beda yaitu masing-masing 96,4 dan 96 % massa. Gas Chromatography (GC) dan Mass Spectrocopy (MS) mendeteksi 14 puncak senyawa dan bahwa 3 puncak tertinggi yang menunjukkan bahwa kandungan sampel adalah suatu metil ester. Masing-masing puncak garis 4 merupakan metil palmitat (C17H34O2) dengan luas area 36,66 %, puncak garis 6 adalah metil oleat (C19H36O2), luas area 55,7% dan waktu retensi 17.92 menit ; puncak garis 7 adalah metil nonadekanoat (C20H40O2) dengan luas area 4,41% dan waktu retensi 18,093 menit.

Abstract

Research has been carried out on the effect of using used cooking oil 6, 8 and 10 times usage on the % yield of methyl ester formation (biodiesel) using a homogeneous base catalyst of 0.6% mass NaOH. All used cooking oil samples were reacted with methanol with a reactant ratio of 1:5 % by mass. The transesterification reaction of each sample was carried out at 60°C for 40 minutes. The yield of used cooking oil samples for 6 times of use was 96.6%, while 8 and 10 times of use showed values ​​that were not much different, 96.4 and 96% by mass, respectively. Gas Chromatography (GC) and Mass Spectrocopy (MS) detected 14 peaks of the compound and that the 3 highest peaks indicated that the sample contained a methyl ester. Each peak of line 4 is methyl palmitate (C17H34O2) with an area of ​​36.66%, peak of line 6 is methyl oleate (C19H36O2), area of ​​55.7% and retention time of 17.92 minutes; the peak of line 7 is methyl nonadecanoate (C20H40O2) with an area of ​​4.41% and a retention time of 18.093 minutes.
