Abstract

Electrical energy has become a vital necessity for today^s life. However, the supply and distribution are still limited and uneven. Therefore, alternative electrical energy that utilizes natural resources in the region is needed. Kotawaringin Timur is one of the areas with abundant potential for peat water, but has not been fully utilized, this water has an acidity level (pH) ranging from 5-2, and contains metal elements, one of which is iron ion II or Fe2+ from laboratory test results of qualitative and quantitative. The content of Fe2+ ions makes it possible to produce electrical energy. In the electrical process using an electrochemical system in which the Galvanic and electrolysis reaction processes occur. Then the experiment was carried out using 27 Zn & Cu plates as anode-cathode and connected in series in the box. The experiment produced an electric power of 0.41 W, a voltage of 16.18 V and a strong current of 8.51 mA measured using a multimeter so that it could turn on a 12V LED for 33 hours. The utilization of peat water which is very abundant as a source of electrical energy is expected to increase the supply and distribution of electrical energy in order to meet the current demand and distribution of electricity, especially in areas that have not received electricity at all.
