Modification of Automatic Alkaloid Removal System for Dioscorine

Dioscorea hispida (D.hispida) is a poisonous plant which their tuber contains toxic poison and can be consumed after the poison or dioscorine is removed. The tubers were peeled, sliced and soaked in flowing water (river) up to 7 days during traditionally detoxified process. Due to the traditional processing methods for removal of dioscorine is difficult to practice, we develop spin type of equipment based on their water circulation operations. This project consisted the stages of design, fabricate and testing for the development of stand alone dioscorine removal equipment. Survival of Cyprinus carpio fish in slicing tuber of D.hispida extraction was used as a tool for detection of dioscorine removal. The manual operation for water inlet and outlet for dioscorine removal system will replace for automatic operation by using on / off solenoid valve while the Peripheral Interface Controller (PIC) is use for controlling input and output signal from sensor, solenoid valve and motor pump. Conceptually, the system will enhance with automatic timer which will pour out the dirty water and refill new water from inlet automatically.
