N2 - The Microbial Desalination Cell (MDC) is one of the energy efficient methods to desalinate sea water developed from the Microbial Fuel Cell (MFC) employing the metabolism of microorganisms. In this study, we utilized microorganisms from Universitas Indonesia (UI) lake water as substrate and coconut shell charcoal as bio electrode instead of conventional electrodes. Coconut shell charcoal is known to have good performance capability in MDC system, low price and environmentally friendly. We used sodium percarbonate (NP) that has excellent buffering capability as a catholyte and UI lake water as an anolyte in our MDC system. With this, we could reduce the cost of sea water desalination process and at the same time we could manage to overcome pH imbalance which commonly occur in MDC system. The optimum result of the seawater model desalination after 50 hours was obtained from the MDC system employing NP concentration of 0.15M. The salt removal (SR) was 15.14% with desalination rate (DR) of 0.1876mmol/hour.
