Research is done to analyze coconut branch fiber as car body composite. Analyzing is based onmaterial, composition, and strength of material. Research was done in laboratory. Coconut branchfiber is obtained by natural drying process and cutting to become fiber with Â±0,5 mm of length.Reinforcement and binder is determined polyester resin. Coir (coconut fiber) have 1.15 kg/m3 ofdensity, 1.15 MPa of strength dan modulus elastisitas 4 â€“ 6 GPa. And based on specimen and studyof literatures can show that increase of cellulose of natural fiber will increase modulus of elasticity.The Increasing of modulus of elasticity will be maximal with cellulose more than 60%. Color ofspecimen is transparent yellow.

Lubrication is important parameter in whole operation in diesel engine, bad lubrication will affect trouble inoperation lubrication have double function decrease friction and cooling. So lubrication has to be treatmentto increase quality by cooling method. Cooling method is done with bat exchanger of shell and tube type. .

Dryer machine of wood is made to fulfill need of wood in order to produce raw of drying wood is notdepended weather. Making of dryer of wood usually requiree investment cost more expensive . it is heavyfor home industry .Inovation of simple dryer machine is done with flowing steam naturally and base onanalyzing it shows that drying can achieve moistur content 12 persen

PENGARUH TEMPERATUR SOLAR TERHADAP PERFORMA MESIN DIESEL DIRECK INJECTION PUTARAN KONSTAN Murni, Murni

The imperfect combustion process will be a problem in the development effort of diesel engineâ€™s performance.Nonhomogen airâ€“fuel mixing process is one of the factors which cause the imperfect combustion.By heating upthe diesel solar up to a certain temperature before it goes through the high pressure injection pump will lowerits density and viscosity. Therefore, when injected in the combustion chamber, it will formed smaller droplets offuel spray which result in a more homogenious airâ€“fuel mixture. Also by using higher temperature will make thediesel fuel easier to ignite in order to compensate the limited time which is available in high speed operatingconditions. Diesel engine Dong Feng 1 cylinder direct injection at constant speed was used in this research. Thefuel used are solar with temperature variations in the range from 30oC to 70oC . The best thermal efficiency forsolar fuel is 30 % at 60oC with 28 % BSFC. In this condition, the fuel consumption was decreased 4 % bycomparing with that at 30oC.
