Abstract

Coffe is one of the results of the commodity plantation that has a fairly high economic value among other crops and plays an important role as a source of foreign exchange, to create a taste of coffee and sold on the market, the important things are the selection of coffee beans and roasting processes. The tools currently existing are still roasted manually and semi-automatic. This research aims to design the tool automatic coffee roast system, analysis the feasibility roasted include capacity analysis.

Abstract

Biodiesel production from calophyllum inophyllum be obtained via esterification and transesterification, using two continuous reactors with catalyst NaOH at a concentration (0.4 ;0.6,0.8; 1) wt%, calophyllum inophyllum seed oil and reaction temperature (40, 50,60)oC. This research was to determine the effect of catalyst amount and reaction temperature on transesterification of calophyllum inophyllum seed toward yield Fatty Acid Methyl Ester . The last step is analysis yield of Fatty Acid Methyl Ester with Gas Chromatography (GC). The highest yield is obtained on the amount of 1% NaOH catalyst and at a temperature of 60oC with yield of 87.036%.

Abstract

Utilization of rice husks in Indonesia in general is still very limited. Utilization of silica contained in rice husk ash, which has been used, among others, in the manufacture of sodium silicate. Silica compounds themselves can be used in and manufacturing basic materials for electronic and ceramic equipment, glass, rubber, cosmetic products, and pharmaceuticals. The addition of Mg can increase the silica content (SiO2) in rice husk ash. The best results show an effective Mg ratio of Mg addition to increase silica content is 1: 1. produces the highest amount of silica which is 58.12% of the rice husk ash with a size of 140 mesh
