【 摘 要 】

This research focused on Electrical Energy Harvesting using taro leaves colocasia esculenta L coated electrode and water droplet passed. The advantage of this research lies in the concept of hydrophobic using natural material from taro leaves colocasia esculenta L, so it is environmentally friendly. In this study using an external circuit of capacitors and bridge rectifier that are connected with aluminum foil as electrodes. From the results, shows that optimal voltage and stable at three drops/second with a slope of 150 degrees produces 78 mV. Electrical energy can be produced because there are energy triggering electrons to jump. Energy obtained from the repulsion of the structure of the leaf surface morphology and the attraction of the element O (oxygen) in the water droplet triggers the surface to become more superhydrophobic. The superhydrophobic surface of the leaf as a membrane to deliver ion flows through the electrode as the way charge flows to the capacitor that is read as the voltage on the oscilloscope. Between the water droplet and the leaf surface, generate the contact angle, so the leaf surface to become superhydrophobic. The role of superhydrophobic properties and slope of the leaf surface is significant to produce electrical energy.
