Abstract

Skeletonema costatum adalah salah satu diatom yang dapat dijadikan sebagai bahan baku biodiesel melalui adanya kandungan Fatty Acids Methyl Esters (FAME). Kandungan asam lemak berupa monounsaturated fatty acids (MUFAs) dan polyunsaturated fatty acids (PUFAs) yang terdapat pada mikroalga yang berpotensi untuk pendukung bahan baku biodiesel antara lain asam oleat (C18:1), asam linoleat (C18:2) serta beberapa jenis asam lemak lainnya. Penelitian ini bertujuan untuk mengetahui biomassa kering serta profil lipid mikroalga Skeletonema pada Cekaman Nutrisi (N & Si) serta Cekaman Abiotik (Aerasi & Fotoperiode) sebagai kandidat bahan baku biodiesel. Penelitian ini menggunakan metode pengukuran biomassa kering Skeletonema dengan Haemocytometer serta analisis profil lipid berdasarkan studi literatur sebagai data sekunder. Pada studi literatur diketahui bahwa cekaman nutrisi serta cekaman abiotik berpengaruh terhadap biomassa A2F2N1 (Aerasi 24 jam, fotoperiode 24:0 dan KNO3 75 gr/ml + NaSiO3 30 gr/ml) sebesar 1,85 gram yang dapat mempengaruhi mekanisme pembentukan lipid TAGs pada mikroalga khususnya diatom dan menghasilkan profil lipid Skeletonema berupa asam palmitate; asam mirstat serta asam oleic yang berpotensi sebagai bahan baku kandidat biodiesel. ==================================================================================================================Skeletonema costatum is a diatom that can be used as raw material for biodiesel through the presence of Fatty Acids Methyl Esters (FAME). The content of fatty acids in the form of monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) in microalgae has the potential to support biodiesel raw materials, including oleic acid (C18: 1), linoleic acid (C18: 2) and several types of fatty acids. other. This study aims to determine the dry biomass and lipid profile of Skeletonema microalgae on Nutritional Stress (N & Si) and Abiotic Stress (Aeration & Photoperiod) as candidates for biodiesel feedstock. This study used the Skeletonema dry biomass measurement method with Haemocytometer and lipid profile analysis based on literature studies as secondary data. In the literature study it is known that nutritional stress and abiotic stress affect the A2F2N1 biomass (24 hours aeration, 24: 0 photoperiod and KNO3 75 gr / ml + NaSiO3 30 gr / ml) of 1.85 grams which can affect the mechanism of formation of lipid TAGs in microalgae. especially diatoms and produce a Skeletonema lipid profile in the form of palmitic acid; mirstic acid and oleic acid which have potential as raw material for biodiesel candidates
