Abstract

Biodiesel berbasis mikroalga merupakan sumber energi alternatif yang cukup berpotensi karena sel mikroalga memiliki lipid yang dapat diproses lebih lanjut menjadi bahan bakar biodiesel. Chlorella vulgaris memiliki kadar lipid 14%-22%. Tujuan penelitian ini untuk memperoleh Lipid mikroalga menggunakan 2 metode. Lipid mikroalga disintesis dengan dua metode yang pertama dilakukan esterifikasi dengan metanol dan katalis asam (H2SO4) pada suhu 55oC selama 1 jam. Kemudian dilanjutkan dengan transesterifikasi dengan metanol dan katalis basa (KOH) pada suhu 55oC selama 1 jam. Metode pertama menghasilkan biodiesel sebesar 76,43%. Metode kedua langsung dilakukan transesterifikasi dengan metanol dan katalis asam pada suhu 90oC selama 40 menit, dihasilkan biodiesel sebesar 85,5%. Biodiesel dari kedua metode sintesis tersebut kandungan metil ester palmitat yang paling dominan. Kata kunci: Chlorella vulgaris , biodiesel, transesterifikasi. / Microalgae-based biodiesel is an alternative energy source that is quite potential because microalgae cells have lipids that can be further processed into biodiesel fuel. Chlorella vulgaris has a lipid level of 14% -22%. The purpose of this study to obtain microalgae lipids using 2 methods. Microalgae lipids were synthesized with the first two methods of esterification with methanol and acid catalyst (H2SO4) at 55oC for 1 hour. Then proceed with transesterification with methanol and base catalyst (KOH) at 55oC for 1 hour. The first method produces biodiesel at 76.43%. The second method was directly transesterified with methanol and acid catalyst at 90oC for 40 minutes, biodiesel produced 85.5%. Biodiesel from the two synthesis methods contains the most dominant methyl esters of palmitate. Keyword : Chlorella vulgaris, biodiesel, transesterification.
