Abstract

The survey results in several tofu industries in West Java, on average, still use manual tools. The process of making traditional tofu takes a long time to press, so it requires new technology, a tool that is easier to use and does not take a long time. Technology of tofu pressing tool with time delay valve pneumatic system is here to solve this problem. This tool is an automatic pressing device designed to replace the manual press. This time delay valve system also has the advantage of being able to work automatically by itself, thereby reducing work and time spent more efficiently. The purpose of this activity was to produce a tofu pressing device technology design with a time delay valve pneumatic system for optimization of the production process. The method used in this study was DND. The stages taken are identification of the problem, describing the objectives, product design and development, product testing and evaluation of trial results, communicating the test results. Data collection techniques are observation and documentation study. The design and testing process used Inventor and FluidSIM-P 4.0 software. This research has resulted in designs of pneumatic cylinders, pressure plates, tofu product storage containers, tool frames, and compressors. The test results show that the tofu pressing device with a time delay valve pneumatic system can increase the productivity of tofu making in the home tofu industry.
