Abstract

Experiment is done to know the performance of “teri/stolephorus” fish drying with forced air flow system. Theperformance of fish drying is based on moisture of fish, fan/fan velocity, operation temperature and time. Theresearch is done at laboratory by using drying machine with forced air flow system. Based on data analysis itshows that the moisture of fish achieves 20% on fan velocity maximum 2,8 m/s and times operation 3 hours

Abstract

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 ±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 – 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.
