The use of energy from environmentally friendly plant-based materials into an effort to assist communities in sufficient of national energy needs. Some processing of Nyamplung (Calophyllum inophyllum L) oil production is drying and pressing to produce crude oil. Degumming process is then performed to remove the sap contained in the oil. The next process is to remove free fatty acids (FFA) below 2% that can cause corrosion on the machine when in use. The results performed of the density properties quality to produce oil that appropriate with the international standards by time variation of catalyst. The result was obtained the density value of 0.92108 gr/cm3 at the time of 3 hours by trans-esterification process, and the best yield value was measured at 98.2% in 2 hours stirring of transesterification. ## Keywords - Biodiesel - Environmentally friendly - Biodiesel production - Transesterification - Acid value - Pulp and paper industry - Yield (engineering) - Environmental science - Production (economics) - Energy density - Energy consumption - Waste management - Catalysis - Materials science - Engineering - Chemistry - Organic chemistry - Metallurgy - Chemical engineering - Economics - Electrical engineering - Biology - Engineering physics - Macroeconomics - Ecology --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
