The essential purpose of the study was to find out the specific amount of electricity that corn waste materials will generate and what MFC Technology set-up can generate a greater amount of electricity. Five separate trials for Tinigib Visayan White Corn (Zea mays L. var. indentata) and Yellow Corn (Zea mays var. saccharata) were made in the study. Different microbial fuel cell set-up trials were constructed to determine if the mass difference of substrate, air pump application, and size of stranded wire used to connect to the electrode affect the performance of MFC set- up in electricity generation. Results showed that the yellow corn variety has more average voltage output with 0.177 V compared to the white corn variety at 0.167 V after seven days of lab observations, testing, and data recording. Data were analysed and interpreted using an independent sample test of mean showing the voltage output generated between two corn varieties. Results showed that the two corn varieties are suitable substrates in MFC technology to produce alternative electricity generation. The factors mentioned above in designing MFC set-up are effective, but it needs more thorough study and experimentation to refine its model. In the size of stranded wire used in the MFC set-up, results showed that the 2 mm stranded wire has a greater effect in voltage output generation than 0.6 mm stranded wire set-up. On the other hand, the mass difference of substrate and the air pump application has variation in MFC voltage output generation.
