Energy is precious for humankind and our live are depended on it.One of the most versatile energi available is electricity. People nowadays find it hard to live their everyday lide without electricity.There are numorous kind of powerplants depends on how they get the energi, one of them is Hydropower plant. Indonesia has a big potential in developing hydropower since there are a lot of river and waterfall available spreading across the country.. Beside the potency for hydropower, waters are channel through irrigation system to support farmers across the country. It will be better to harvest the power within the irrigation system and turn it to electricity and distribute it to all the people. Irrigation systems tends to have a big debit but low head so we need to apply a water turbine that works perfectly in that kind of condition. Archimedean screw works perfectly in that condition . Two Archimedean screw were made and built in Indonesia but failed within days after operating. In this final project, writer designed a Archimedean screw turbine and upper bearing housing mechanism that worked for condition of 0,087 m3/s As debit and head of 1.m. The turbine will be built in Cihanjuang, CImahi, West Java. This turbine will be operated with 0 degree angle and will generate 0,7087 kW with the efficiency of 81,47 % The upper bearing housing mechanism hold the weight of the turbine and water when operating with a total of2.12 kN in axial direction and 1.835 kN for radial direction. The mechanism containing of two different bearings working for each force direction, Spherical Roller Bearing for the radial load and the Spherical Thrust Bearing for the axial load. This mechanism tolerate misalignment by self aligning itself so the bearing will work perfectly unlike the two powerplant that have built befor and failed instantly.
