Abstract

Nowadays, biocomposite materials are required for particular needs. Coconut husk has a potential to be biocomposite using a resin produced by the laccifer lacca kerr (kerria lacca), an insect. This work was aimed to study the use of the lacca kerr resin to produce a biocomposite of coconut coir based. In the experimental, firstly, the cleaned coconut husks were chopped then mixed with lacca kerr resin and alcohol to make a composite dough. Then the dough were pressed with 130 psig at a 100oC within15 minutes. After that, the biocomposite was allowed to ambient temperature, then it properties were observed. To find the best product properties, the ratio of basic materials were varied. The ratio of coconut husk: lacca kerr resin was used ranged from 0.6 g/mL to 1.4 g/mL. The characterization of product properties were carried out based on ASTM D-638 and under guidance of the Indonesian National Standard (SNI) 03-2105-2006. Based on results, it was found that the best biocomposite observed had properties such as density of 0.45 g/cm3 , water content of 8.8% (maximum SNI requirement of 14%), degree of swelling of 67.6%, tensile strength of 43.4 kgf / cm2 (minimum SNI requirement of 3, 1 kgf / cm2 ), Young's modulus of 1219.2 kgf/cm2 , elongation of 67.7%, conductivity of 1.8 10-8 /.m. Some of these characteristics have met the Indonesian national standard (SNI).

Abstract

 Oil sludge is the solidifying oils that lying on the open space around the fuel storage tank. Heaps of the waste continues to increase could lead to environmental pollution due to the waste containing heavy metal. This research aims to study the effect of oil sludge on the compressive strength of traditional ceramics within range of sintering temperature (600- 1000 0 C), sintering time (1-3 hours), and raw material compositions. The experiment begins by mixing the ceramic raw materials. Material was mixed with water and milled using Mortar Hand (milling). A cermic mold was used to get ceramic specimens. The mold dimension is length of 8 cm, 4 cm wide, and 2 cm high. The specimens were sintered in a furnace at different temperatures and holding time. Finally, the ceramics were observed its compressive strength. The results showed that the waste oil sludge can be involved in the manufacture of traditional ceramics. In the view of the compressive strength, the best conditions for fabricating traditional ceramics are oil sludge of 16.67% w., sintering temperature of 800 0  C, and sintering time of 2.5 hours.
