Abstract

The effect of the transesterification reaction time of 0.6% mass % NaOH catalyst in the formation of methyl ester (biodiesel) made from used waste cooking oil as raw material 6 times usage and methanol 1: 5 mass has been studied at 60°C. The reaction times used were 30, 40, and 45 minutes. All samples resulting from the transesterification reaction have been studied for their chemical and physical properties. Parameters of chemical properties included in the Indonesian National Standard (SNI) for all samples were % FFA, pH, while the water content was above the SNI standard. The physical property parameters for all samples that meet SNI are only flash point, color and 90% distillation. While the density of all test samples was lower than the SNI which was set at 850-890 Kg/m3, the results obtained for reaction times of 30, 40 and 45 minutes were 828, 833 and 836 Kg/m3 respectively. The highest yield was owned by a reaction time of 40 minutes, namely 80%. As for the reaction time of 35 and 45 minutes respectively 79 and 65%.

Abstract

Nipah-Nipah plants grow mostly in the confluence of rivers and seas. This plant has the potential to maximize all parts of the tree. Nipah fruit can be used for Nata Frutican and the basic ingredients for making flour. Unused fruit shells have a hard texture, similar to the texture of coconut shells. To increase the calorific value of this fruit peel charcoal, a pyrolysis process is carried out. The samples were separated from the following waste and dried in direct sunlight. The dry sample is crushed and then put into the combustion reactor. Pyrolysis was carried out at a constant temperature of 500°C with variations in the heating rate of 2°C/minute, 4°C/minute, 6°C/minute, 8°C/minute, and 10°C/minute and holding time for 1 hour. The results showed that the calorific value decreased with increasing heating rate. The highest calorific value is at the lowest heating rate. The calorific value at a heating rate of 2°C/minute is 6841, 02 cal/gram. ; 4°C/minute calorific value is 6811.59 cal/gram; 6°C/minute of 6745.07 cal/gram; 8°C/minute is 6656.59 cal/gram and at 10°C/minute is 6570.41 cal/gram
