<p align="justify">Anaerobic digestion is a well known phenomenon using air-tight container. However, this method needs time to digest the substance and theoretically controlled temperature and pH could shorten the anaerobic digestion time. To be able to control the temperature and pH, reactor with temperature and pH monitoring system should be developed. Therefore, this Final Project is intended to design and build anaerobic digestion reactor with temperature and pH monitoring. <br /> <br /> In this final project, a reactor system consisting 2 anaerobic reactors is designed and built. Thermal isolation is designed to reduce the heat loss from each reactor so that the reactor temperature can reach 35 °C which is suitable to shorten anaerobic digestion time. Two temperature sensors is placed in each reactors and two pH sensors is placed in Anaerobic Reactor I. Calibration process for the sensors have been done and preliminary experiment for seeding was tried. In this time, the measurement is not yet reliable and need further improvement.<p align="justify">
