- Abstract
Biodiesel is fatty acids methyl or ethyl esters made from vegetable oils (edible and non edible) or animal fats. The objective of this research was conducted on production of biodiesel from rubber seeds by in situ method with a goal for environmentally friendly alternative fuels from non edible raw materials. This research focuses on influence of reaction time, concentration of catalyst and ratio of raw materials to methanol. In the first stage was carried out in order to get reaction time based on the density and viscosity of mixture produced. In this process was used H2SO4 0.5% (v/v) and KOH 0.5% (w/v) as catalyst and ratio rubber seed to methanol (1:2). Experiments followed by influencing of catalyst concentration in range 0.1-1% and ratio rubber seed to methanol in range 1:1.5-1:3. Research methods included, the preparation of samples, biodiesel production, biodiesel separation, and biodiesel characterization include density, viscosity, GC analysis, acid value and Iodine number. The results shows that time operation for biodiesel production by using in situ method with acid catalyzed and alkaline catalyzed was 120 and 90 minutes respectively with yield of Fatty Acid Methyl Ester (FAME) was obtained at 91,05% and 58.79% respectively.
