PENGARUH TEKANAN DAN WAKTU TERHADAP PEROLEHAN MINYAK KELAPA DARI KOPRA DENGAN PENEKANAN MEKANIS (HYDRAULIC PRESS) (Effects of Pressure and Time on Yield of Coconut Oil from Copra with Mechanical Pressing (Hydraulic Press)

Abstract

Hydraulic Press is one of the methods that are used in extracting the oil from grains other than by using Solvent Extraction. The main component of the Hydraulic Press is Jack Hydraulic, and supported by other components, namely Tubes Pengepressan, a pressure plate (Piston Pengepress), Handle, Frame and place a container of oil. Coconut (Cocos nucifera L) is a plant whose fruit is used as a source of oil. Palm fruit oil contains quite a lot that is 34.7 grams per 100 grams of oil. Coconut oil including oil group does not dry (non-drying oils). Fats and oils can be obtained from the extraction of animal or plant tissue in three ways, namely rendering, pressing, or with solvent.Two common ways in which the pressing mechanical pressing hydraulic (hydraulic pressing) and pressing threaded (screw pressing). How hydraulic presses require pre-treatment consists of the cooking process or tempering. The object of this research is to study the effects of time and the pressure on palm oil yield. The analysis will be conducted on the products are yield, viscosity, density, acid number and saponification. Keyword : oil, oil coconut, Hydraulic pressing
