The technology development has been continuing to solve the cost problem, aiming to reduce work time, to streamline the existing machines to be more efficient and productive, including designing the devices to replace human labor. In present paper, the author has an idea to develop and transform the old press machine which has faced the issues of the deteriorated helix core, bunt motor when overloaded, less productivity to hydraulic cylinder. This paper examined the development of the coconut oil pressing machine from old model to hydraulic cylinder system. In operating principles, the developed machine uses the motor pumping the hydraulic oil into hydraulic pump, the oil fuel was restricted by hydraulic pump to increase the pressure transmitted to the solenoid valve which is responsible for changing the direction of the oil flow, resulting that the cylinder moves up and down under the control system. The cylinder presses the coconut pulp The study of the development of coconut oil press machine was initiated by drying the 3 kg coconut pulp in the sun to obtain the 0.2038 kg (or 160 ml) coconut oil. In this study, the hydraulic cylinder presses 3 kg dried coconut pulp into 1.1858 kg (or 946 ml) coconut oil, or accounted for 83.08% as compared the old machine. The payback period is within 29 days.
