Abstract

Besarnya nilai power density yang diperoleh dari sistem Single Chamber Microbial Fuel Cell (SCMFC) merupakan poin utama yang perlu diperhatikan dalam memantau performa dari SCMFC. Nilai power density dalam sistem SCMFC dapat ditingkatkan dengan adanya penambahan Fe(III) ke dalam campuran. Fe(III) dalam sistem SCMFC akan berperan sebagai elektrolit sebagai penangkap elektron. Pada penelitian yang dilakukan, diberikan penambahan FeCl3.6H2O untuk meninjau performa dari sistem SCMFC dengan menggunakan isolat LS-ISP2-JS2 (Uncultured Bacterium Clone I) dan LS-ISP2-JN4 (Bacterium Strain BS2049) yang berasal dari Kawasan Gunung Semeru. Pengoperasian sistem SCMFC dilakukan dengan menghomogenkan kultur cair dari masing-masing isolat yang kemudian diberikan larutan elektrolit Phosphate Buffer Saline (PBS) serta larutan FeCl3.6H2O dengan variasi konsentrasi 5 dan 10 ppm sebagai pembanding serta menggunakan elektroda carbon felt. Perbandingan antara volume isolat dengan larutan elektrolit PBS adalah 1:1. Penelitian dilakukan selama 25 hari menunjukkan bahwa nilai power density paling tinggi dihasilkan oleh isolat LS-ISP2-JN4 (Bacterium Strain BS2049) tanpa pemberian larutan FeCl3.6H2O sebesar 2,1330 mW/m2, sedangkan perolehan nilai power density paling tinggi pada variasi penambahan larutan FeCl3.6H2O adalah pada isolat LS-ISP2-JS2 (Uncultured Bacterium Clone I) sebesar 1,8748 mW/m2 pada variasi penambahan 5 ppm larutan FeCl3.6H2O. Hasil penelitian yang diperoleh ini menunjukkan bahwa penambahan Fe(III) pada konsentrasi 5 ppm dan 10 ppm dapat menurunkan kinerja dari SMCFC dengan ditunjukkan oleh adanya penurunan nilai elektrisitas.

The amount of power density value obtained from the Single Chamber Microbial Fuel Cell (SCMFC) system is the main point that needs to be considered in monitoring the performance of SCMFC. The power density value in the SCMFC system can be increased by the addition of Fe(III) to the mixture. Fe(III) in the SCMFC system used as an electrolyte as an electron acceptor. In the research conducted, the addition of FeCl3.6H2O was given to review the performance of the SCMFC system using isolates LS-ISP2-JS2 (Uncultured Bacterium Clone I) and LS-ISP2-JN4 (Bacterium Strain BS2049) isolated from Mount Semeru Area. The operation of the SCMFC system carried out by homogenizing the liquid culture of each isolate which then given a Phosphate Buffer Saline (PBS) electrolyte solution and FeCl3.6H2O solution with a concentration variation of 5 and 10 ppm as a comparison and using carbon felt electrodes. The ratio between the volume of isolate and PBS electrolyte solution was 1:1. Research conducted for 25 days showed that the highest power density value was produced by LS-ISP2-JN4 isolate (Bacterium Strain BS2049) without FeCl3.6H2O solution of 2.1330 mW/m2, while the highest power density value obtained in the variation of adding FeCl3.6H2O solution was in LS-ISP2-JS2 (Uncultured Bacterium Clone I) isolate of 1.8748 mW/m2 in the variation of adding 5 ppm FeCl3.6H2O solution. The results of this study show that the addition of Fe (III) at concentrations of 5 ppm and 10 ppm can reduce the performance of SMCFC by being shown by a decrease in the value of electricity.
