Bioreactor System for the Production of Liquid Biofertilizer

Peneliti: Hilwadi Hindersah

Bioreactor System is a device that functions to multiply microbial cells by cultivating microbes in a Bioreactor tank in a controlled environment. The tank is designed to provide an effective environment for microbial cells to multiply in a liquid medium; and then become a liquid biofertilizer product. The environmental conditions of the Bioreactor tank that need to be controlled are temperature, air pressure, acidity (pH), oxygen concentration, microbial homogeneity, and operating time; so that microbes can grow in optimal conditions to produce maximum cell density. To produce optimal conditions in a bioreactor system, a device is needed to control the system. 

In this study, an interaction device was designed between the user and the Bioreactor system that functions to receive data input from the user and display environmental data output from recordings or what is currently happening online. Then, a controller device that functions to regulate the value that must be generated by the Environmental Conditioning Device and maintain the environment at the desired value (setting point) by the user was also developed in this study.
