Potential Use of Mango Waste and Microalgae Spirulina sp. for Bioelectricity Generation

Potential use of organic waste and microalgae generates bioelectricity thereby reduces harmful effects on the environment. These residues are used due to their high content electron-generating microorganisms. However, so far, they have not been simultaneously. Therefore, this research uses mango Spirulina sp. in double-chamber microbial fuel cells generate bioelectricity. The were made at a laboratory scale using zinc copper electrodes, achieving maximum current voltage 7.5948 ± 0.3109 mA 0.84546 0.314 V, with electrical conductivity substrate being 157.712 4.56 mS/cm an optimum operating pH 5.016 0.086. showed low internal resistance approximately 205.056 25 Ω, power density 657.958 21.114 mW/cm2 4.484 A/cm2. This provides excellent opportunity for farmers exporting importing companies because can own reduce electricity costs when prototype is brought large scale.
