| dc.description.abstract | Water resources are be an source energy alternative that are widely used by many developing countries and developed countries as the main source of national energy. Generally, a power plant that uses water resources requires a large flow of the river or through the dam energy to generate electricity, but the applying of precipitation potencial is not widely done. Nanohydro power plants developed in this study utilizes precipitation that falls onto the surface of building. This tool has a small size and can be moved around (portable/moveable) with simple system to facilitate its use. Due to large precipitation changing over time, then the utilization of rainfall is conditioned prior to reaching the minimum required discharge limits to rotate and maintain the turbine rotation. Minimum flow required to rotate and maintain the turbine is about 4-5 liters per second. Nanohydro power plants have an efficiency of 5,23% with a tool for value and efficiency of the turbine generator efficiency of 40,96% and 12,76%. Turbine of the power plant can be spun at a speed of 60 rpm with 0.4 height and flow rate of 5 liters per second. With the rotational speed of the turbine, nanohydro power generation can produce power about 2 watt and can turn on the 3 watt LED lamp with a light level of ignition criteria. | en |
