The mechanical behavior of oil palm empty fruit bunch (OPEFB) reinforced polymer composites-polymeric foam sandwich panels are treated as experimental investigation for side body molding appliance. In this research, oil palm empty fruit bunch (OPEFB) fiber will be processed as polymeric foam mixture. This material is subsequently used for the sandwich structure of the impact absorption sandwich panels on the motor vehicle supporting components. OPEFB that has been obtained and then grab the fiber by cut and separated from the OPEFB rod. The separated fibers were treated. It could be know how OPEFB fiber reinforced polymer composites sandwich panels has energy absorption. The experiment is conducted by means of static test. The mechanical behavior of OPEFB fiber reinforced polymer composites-polymeric foam sandwich panels was performed. The microstructure was observed using SEM observation in order to better understand damage mechanism. Based on the static uniaxial tensile and flexural loading results, the mechanical behavior was determined and it was found that fiber treatment influence the tensile and flexural strength of OPEFB fiber reinforced polymer composites-polymeric foam sandwich panels.

Indonesia is located in an equatorial area at latitudes less than 20 degrees covered by 77% ocean, thousand islands, strain and many difference of topography is very compatible to build OTEC system. This paper discussed drag of cold water pipe of offshore floating OTEC. As a case study, I MW of OTEC to be applied in Selat Makassar was simulated. In the simulation, site measurement data of sea current profiles for a year and sea temperature profiles in 2009 and 2012 were used. Result of simulation shows that drag of cold water pipe was potentially high at water level of 0 to -300 m and during July-September.
