Abstract

Copra is a pulp of a fresh coconut that is dried, known as two kind, that is white and black copra. Copra drying process can be divided into two part, that is initial process which is to dried a coconut pulp with the shell containing water 55% until 35% of water and final process which is to dried a coconut pulp which contain 35% of water to be 7-8% of water. The problem in copra drying process is the uneven drying temperature and duration. Therefore, this research aims to optimize the copra dryers tool, especially at the of the initial process drying. Method of this research is by redesign copra drying tools of initial process, calculate thermal process and total heat that needed for drying process by using Microsoft visual basic. Results of the research were obtained for the copra drying process by using pipe 1 inch of diameter and length 39.12 cm, with the dimension of drying tools is 270 cm x 180 cm x 180 cm and material construction is a zinc wall with asbestos layer. And the drying temperature of copra is 74.51 oC with total heat needed is 501,858.1 kJ and drying process takes 3.65 hours. Keyword: Copra, Redesign, Microsoft Visual Basic, Drying Process
