Abstract

Electrical energy has become a part of our lives. Even, for some people has become the primary requirement that can’t be eliminated. This can affect the sources of energy used in the process of power generation. Therefore, the presence sources of renewable energy is needed to increase the energy supply for the community. In this case, authors tried to do some research to harness the flow of water in the PDAM Way Sekampung pipe as micro hydro power plant (MHP) The advantage of making the MHP's pipeline PDAM isn’t need for the manufacture of civilian buildings by making MHP is only by utilizing the existing water flow in a pipeline, so the production cost can be reduced. Moreover, can give an idea on the PDAM and the public that the pipeline PDAM that had been used only as a water distribution, can be used as power plant. The purpose of this study was to determine the discharge and head PDAM pipelines and then dimensional turbine design based on the potential obtained. The survey was conducted to obtain primary data and secondary data. The primary data is data acquired directly, while secondary data is the data obtained from documents stored on PDAM Way Sekampung. From the research, discharge obtained an average of 46.287 L/s in normal conditions, and have the water level (head) of 5,998 m from the location of the turbine. The potential of the PDAM Way Sekampung, can generate power of 2,057 Kw. Results dimensional turbine design based on primary data or the direct retrieval, turbine shaft diameter 20 mm, 239 mm runner diameter, blade length 212 mm, a thickness of blade 1 mm and blade number 20.Keywords: Energy, Potential, Micro hydro, cross-flow turbine

Abstract

Electricity is very important in human life. In Indonesia,electricity is a basic necessity for society and industry. Electrical energy supply in Indonesia is targeted to use the 5% comes from renewable energy, it has been included in the government regulation No. 3 of 2005. One of the power plants that are potentially is Micro Hydro Power (MHP), which is an implementation of the green energy initiative to encourage renewable energy step. If the MHP potential can be developed, then at least 12,000 MWh or 14% of Indonesia's total energy needs in 2005 are contributed by the MHP.The purpose of this final project: " Feasibility Study of micro hydro power plant (MHP) on arter river at hurun village Padang Cermin district Pesawaran region lampung " is to plan a hydroelectric small scale power plant that can be used and applied as a fulfillment of electrical energy in Indonesia, especially for people who can not enjoy electricity.The Procedures to obtaining data for Head cleaner using a plastic hose method and calculation method, so the net head of 11.15 m obtained. To determine the amount of water flow, the method used is the method of floating objects, as well as doing some calculations and obtained intake capacity of 66.7 l / s. And the resulting power of 5.10 Kw. From data result, turbine suitable types is crossflowtubine.Keywords: micro hydro power plant, water discharge, crossflow turbine.
