Bioelectricity Generation from Bamboo Leaves Waste in a Double Chambered Microbial Fuel Cell = (Penjanaan Bioelektrik daripada Sisa Daun Buluh dalam Sel Bahan Api Mikrob Dua Kebuk)
This study investigated the utilization of bamboo leaf waste and two varieties of bacterial sources, chicken manure
and effective microorganism, in a microbial fuel cell (MFC) at three substrate concentrations (40 g/liter, 80 g/liter, and 160 g/liter). The primary objective was to investigate the kinetics of bacterial growth at various substrate concentrations in the MFC, as well as the effect of light conditions and pH on MFC power generation. The MFC had dual chambers with graphite electrodes serving as the cathode and anode. Within 72 h, the highest power density of 90.05 mV
was attained using the highest substrate concentration of bamboo leaf waste and chicken manure during the logarithmic
growth phase, albeit with a shorter duration. The longest sustained phase of bacterial activity was observed during
the stationary phase, at the highest substrate concentration of 160 g/liter, followed by 80 g/liter and 40 g/liter. These
results indicate that the logarithmic phase is the optimal time for bacterial activity in the MFC. However, attaining
long-term stability in power generation in the logarithmic phase requires careful parameter optimization

Fabrication of single chamber microbial fuel cell (SMFC) using soil as a substrate
This paper presents a Single-chamber Microbial Fuel Cell (SMFC) design by utilizing soil as a substrate with two sets of electrode combinations, which are graphite-activated carbon and copper-zinc of different sizes. It was found that graphite and activated carbon produced greater power density compared to copper and zinc. Moreover, it was observed that the graphite-activated carbon cloth electrode with a bigger surface area of 51cm2 resulted in a higher power density of 904mW/m2. To further improve the voltage production of this model, four SMFCs were stacked in series and connected to a DC-DC boost converter to increase the voltage to 1.482 V for the copper-zinc electrode and 1.722 V for the graphite-activated carbon electrode, respectively, which was sufficient to light up an LED light
