Alternatif Bahan Baku Biofuel Dari Mikroalga Chlorella Pyrenoidosa Yang Dikultivasi Dengan Variasi Intensitas Cahaya Dan Konsentrasi Palm Oil Mill Effluent (Pome)

Energy scarcity is the one of world’s serious problem nowadays. A lot of research has been done to solve this problem. One of them is the innovation of biofuels from microalgae. The lipid and carbohydrate content of microalgae can be converted into biodiesel and bioethanol. Earlier research reported that Palm Oil Mill Effluent (POME) is a potential medium for microalgae to growth because it contains high nutrient sources. Microalgae has the ability to remove pollutans in POME such as COD dan total nitrogen by utilizing them as growth nutrients. The microalgae used in this research was Chlorella pyrenoidosa. C. pyrenoidosa is one of microalgae that grows and develops in the POME pond. The purpose of this research is to determine the effect of variations in POME concentration and light intensity on cell formation, carbohydrate content and lipids of C. pyrenoidosa. C. pyrenoidosa cultivated in POME : Medium Dahril Solution (0:100; 25:75; 50:50; 75:25; 100:0) with light intensity (3000±300 lux, 4000±300 lux and 5000±300 lux), aerated using air pump with flow of 3 L/min and fluorescent LED lights as light source with a lighting duration of 12:12 hours. The results showed the best cultivation conditions at the POME : Medium Dahril Solution ratio 50:50 with the light intensity of 3000±300 lux producing microalgae with cell density of 4,125 x 107 cells / mL, lipid content of 42,86 % and carbohydrate concentration of 289,69 mg/L with efficiency total COD and total nitrogen 91,67 % and 90,23 %.Keywords: Chlorella pyrenoidosa, Palm Oil Mill Effluent (POME), Dahril Solution Medium, Lipids, Carbohydrates, COD, Total Nitrogen.
