Electrical tree phenomenon is a long term degradation and can be found in solid insulator material. Its phenomenon will degrade the characteristic of insulator and may lead to breakdown. The use of filler in the process of manufacturing for the insulation is very popular method. This paper presents the use of coconut shell powder (CSP) filler in epoxy resin for inhibition of electrical tree growth. The CSP is filled with in ratio of 0.1, 0.3, 0.5, 0.8 and 1.0% by weight. The electrical tree was tested by AC voltage of 15kV and conducted for 30 minutes in this experiment. Experimental results shown that, the pure epoxy resin using as a controlled has tree length of 3.20 mm. While the epoxy resin using CSP filler of 1% by weight has a tree length propagation of 2.10 mm. The shorten length of electrical tree may be affected by the combination of modified permittivity (Ɛ) value of an insulator. Also, this study has shown that the CSP may be a potential candidate as a filler compound to be used as electrical tree inhibition for electrical insulation system.

The purpose of this research is utilization of coconut shell powder on Al2O3-Epoxy composite so it can be used as an alternative material of brake linings that are enviromentlly friendly. In this research, coconut shell powder is used as a filler on Al2O3-Epoxy composites that are made using hand lay up method. Comparison volume fraction of coconut shell powder and Al2O3 was varied amount 0:40, 10:30, 20:20, 30:10 and 40:0 (%). Adhesive was used is epoxy resin namely amount 60%. Test conducted is wear test. The results showed that utilization of coconut shell powder on Al2O3-Epoxy can be decrease the wear so it can be used as an alternative material of brake linings that are environmentally friendly

Coconut shell is one of agricultural wastes that having low commercial value. This research is objected to use coconut shell as the base material of producing surfactant. The use of coconut shell is basically due to its content of lignin, about 29,4%. The objective of this research is to obtain isolate lignin with increasing chatalis NaOH and H2SO4 with lignin identification, the effect of temperature and agitation rate of producing surfactant. The research was done in a reactor with temperature of 100 0C, 110 0C, 120 0C, 3 hours reaction time, pH 6, 80 rpm, 90 rpm, 100 rpm agitation rate, and coconut shell as the base material. Dry coconut shell is grinded and the powder is collected to be reacted. The coconut shell powder is reacted with sodium bisulfite solution with variation in ratio of 1:0,5.  The product is filtered to get filtrate and residue. The filtrate is further analyzed by using the FT-IR spectrophotometry method. From the research we get maximum purity of surfactant at sodium bisulfite with reactant ratio of 1:0,5;  Speed 100 rpm and temperature 120 0C.
