Coconut Shell Powder (CSP) was derived from industrial Making Anti-Mosquito can potentially be used as filler in materials composite. The investigation on the utilization of CSP as filler in a polyester matrix has been done with the purpose to obtain the best CSP fillers size in Unsaturated Polyester (UPR) composites in producing the best mechanical properties such as tensile strength, impact strength  and water absorption. In this study, UPR was mixed with CSP at the sizes 50 mesh, 70 mesh and 100 mesh with comparison of CSP: Unsaturated Polyester 20:80 (w/w) by using hand lay-up method. The result of mechanical properties showed that, at a ratio of CSP: PE (20:80), the maximum tensile strength obtained is 42.558 MPa with the size of CSP 70 mesh. The test on impact strength was found that the increasing only occured with the size of CSP 100 mesh at 6083.47 J/m2. For absorption test, the highest water absorption occured at the first day,  water absorption increased with increasing the amount of filler and the most CSP  absorbed  water at 70 mesh.

The feasibility of using coconut shell powder (CSP) and dog conch shell powder (DCSP) as carburizing media in the pack carburization of SCM 420 steel was investigated. The carbon content and surface hardness of the carburized specimens prepared with different CSP:DCSP ratios and carburizing durations were examined and compared. A CSP:DCSP ratio of 60%:40% and an extended carburizing time of 12 h were found to increase the carbon content of the carburized specimens to 1.14 ± 0.007 wt%. Furthermore, the surface hardness was significantly improved to 961.3 ± 4.918 HV following water quenching. Finally, the thickness of the carburized layer of the quenched specimens increased by around 2.5 times as the carburizing duration was increased from 3 to 12 h.
