"Jurnal Energi dan Manufaktur" is a journal published by Department of Mechanical Engineering, University of Udayana, Bali since 2006. During 2006-2011 the journal's name was "Jurnal Ilmiah Teknik Mesin CAKRAM" (Scientific journal in mechanical engineering, CAKRAM). "Jurnal Energi dan Manufaktur" is released biannually on April and October, respectively. We invite authors to submit papers from experimental research, review work, analytical-theoretical study, applied study, and simulation, in related to mechanical engineering (energy, material, manufacturing, design) to be published through "Jurnal Energi dan Manufaktur".

Abstract

Evaluation to determine production parameters of material for train brake that is environmentally friendlyby using serat tandan kosong kelapa sawit (TKKS) as reinforcement was done by using extensionevaluation method. The research was carried out with variations some of parameter productions or bymaking material such as pressure load, pressure time and temperatures. The samples then were testedbased on criteria from the technical specification for composite brake from PT KAI. It is obtained fromthe testing that the best parameter productions are: Pressure 15 ton, pressuring time 40 minutes, andtemperature is 200oC. The result from evaluation indicate that sample S14 as the the best sample thatapproach technical spesification from the PT. KAI

Abstract

Duct system is connecting between the refrigeration system and room to be conditioned. Room airstreamed into the cooling coil through the return duct intake, air filters. Furthermore, the air sucked by theblower, which flowed into the evaporator. Through the register box, air conditioned which has flowed backinto the room. When flowing inside the duct, the air has obstacle. One inhibiting factor is the change indirection of flow due to bends. That occurs at elbow is caused by friction (friction loss) and flow separation(separation loss). The aims of this research is to examine the phenomenon of the flow with Re = 3824 x104 on a rectangular elbow as well as knowing how to influence the guide vanes at the elbow ductingchannels. Based on data from research results, the number of guide vanes and position affects thepressure drop. From the graph shows that the installation of guide vanes to reduce pressure drop whenfluid flows through the elbow. Installation guide vanes with the number five result in the smallest pressuredrop of 9.1%. Efficiency caused by the installation of guide vanes reached 27.6%. Can be concluded thatthe installation of guide vanes on the elbow can be used as a reference in the design of ducting so asreduce the energy consumption.
