Abstract
Penelitian ini dimaksud.kan untuk mensintesis metil ester dari lipid bakteri Bacillur stearothermophilur melalui reaksi transesterifikasi dengan men~'Uilakan katalis BF 3 dalam methanol (14%). Ekstraksi lipid bakteri dilakukan dengan menggunakan pelarut kloroform : metanol (2:1). Lipid yang diperoleh ditransesterifikasi menggunakan BF3 dalam methanol (14%) dan dianalisa dengan Kromatografi Gas - Spektroskopi Massa (KG-SM) untuk menentukan pola asam lemak. Kadar lipid total bakteri B. stearothermophilus yang diperoleh dalam penelitian ini 0,113 gig sel kering (11,3% terhadap sel kering). Merit ester total basil transesterifikasi sebanyak 0,0206 g atau 0,9115 gig lipid total (91,15%). Hanya terdapat satu jenis metil ester asam lemak yang teramati dalam lipid H. stearothermophilus yaitu metil palmitat sebesar 4,47% atau sebanyak 0,9208 mg dari massa metil ester total.

The objective of this observation is to synthesis methyl ester from lipid of Bacillur stearothermophilur by transesterification using BF3 catalyst in methanol (14%). Extraction of lipid that had been done using chloroform : methanol (2:1) solvent. Total lipid content of the bacteria R. stearothermophilus obtained in this study is 0,113 g/g dry cells (11.3% of dry cells). Transesterification using BF3 produced methyl ester 0.0206 g or 0,9115 g/g total lipid (91.15%). Methyl ester analyzed using Gas Chromatography - Mass Spectrometry (GC-MS) show that only one type of fatty acid methyl esters were observed in B. stearothermophilus's lipids. The fatty acid methyl esters is methyl palmitate as much as 4.47% or 0.9208 mg of the total mass of methyl esters.
