Abstract

One of the problems being faced in several regions in Indonesia is the source of electrical energy. The demand for electricity from year to year has increased. The development of free energy technology needs to be developed to cover the rapidly increasing demand for electricity. One that can be developed is micro-hydro power plant technology that utilizes water flow as a source of electricity. To make a micro hydro power plant, it is necessary to do research on the available discharge and how much energy and power is generated at that location. The purpose of this community service activity is to help the community find out the potential of river flows in Toba Village, South Siantar District, Pematangsiantar City in its utilization for micro hydro power plants. The method of implementing the activity is Head observation (falling height), river flow velocity, river width, and river flow depth. From the results of observations and measurements of discharge at the service location, it is known that the head (fall height) is 0.5 meters, the river flow speed is 0.74 m/s, the river width is 6.5 meters and the river flow depth is 0.3 meters so that an empirical calculation of the generator discharge is obtained at 1.433 m3/sec., and the power that can be generated is 7.08 kW.

Abstract

River pollution is the entry of various substances and non-biodegradable objects that result in contaminated water and loss of function. Besides being a source of various diseases, water pollution also causes flooding. Protecting the river is the same as maintaining survival in the future. Rivers have been the most important part of human life since ancient times. In human evolution, rivers and lakes played an unimaginable role. Rivers are not only important for animals and birds to live, but are also a major source of drinking water. And their environmental value, economic value, and spiritual value touch everyone in the world. In India, people at one time even worshiped rivers as life-giving gods and goddesses. The reason is that every time we search for life, we look for a drop of water first. Rivers carry water and nutrients to areas around the earth. They play a very important role in the water cycle, acting as drainage channels for surface water. Rivers flow almost 75% of the earth's land surface.
