520			_aThe increasing global energy demand necessitates the exploration of alternative renewable energy sources. Microbial fuel cells (MFCs), which utilize microorganisms to convert organic matter into electricity, offer a promising solution. This study investigates the bioelectrical potential of organic compost soil and Pasig River silt as fuel substrates using graphite-coated electrodes in a single-chamber microbial fuel cell (SCMFC). Key parameters of the MFC setup, including electrode binder, electrode size, and electrode spacing, were optimized to maximize output voltage. Five different SCMFC setups were constructed using pure Pasig River silt, compost soil composed of garden soil, vermicast, chicken manure, cow manure, cocopeat, carbonized rice hull, and fresh rice hull, and their mixtures in varying ratios (1:1, 1:3, 3:1). Characterization and quantification of isolated bacterial colonies, along with physicochemical properties such as soil color, consistency, texture, bulk density, moisture content, pH, and macronutrient levels, were analyzed before and after the evaluation. The open circuit voltage (OCV) of the MFC was measured over 30 days. Results indicated that optimal conditions for maximizing output voltage included sucrose as the binder, electrodes of 8.2 cm diameter and 4.1 cm radius, and 4 cm spacing between electrodes. The highest voltage output, 631.0 mV, was achieved with a 3:1 mixture, while pure compost soil and pure river silt produced lower voltages of 257.0 mV and 60.0 mV, respectively. These findings suggest that utilizing locally available organic materials like compost and river silt in MFCs can generate electricity while aiding waste management and promoting renewable energy.
