Abstract

This project used the PLC (programmable logic controller) as the controller in order to control the leaching process of Nata de Coco. This project can be separated into two parts which are hardware and software. The hardware part consists of developing the structure that absorbs tanks, valves, cages and pipes. Meanwhile the software part is developing the ladder diagram which is control the entire process after transfer it into the PLC. This project applied the touch screen to allow the users to control and monitor the leaching process of Nata de Coco. Beside that, the air pressure is used in this project to rolling the Nata de Coco in the tank while the leaching process. The pH paper used to measure the level acidity of Nata de Coco in order to stop the leaching process after pH’s value achieves the neutral level. Lastly, the analysis is making to study production of Nata de Coco in large scale. By developing of this project, the leaching process of Nata de Coco with manually in small medium industry sector can be replaced with automatic system in order to increase the productivity and reduce the cost of manpower.
