Abstract

Mini Hydro Power Plant (MHPP) is a Hydro Power Plant that generates electrical energy within 100 KWH to1 MWH. MHPP on non-ground water in Bekasi watershed located on 6º28’16,66’’ S - 106º53’48,75’’ E for Bekasi Upstream Weir and 6º27’57,06’’ S - 106º53’39,75’’ E for the power house. Bekasi Upstream Weir is located on Cileungsi River stream and the power house is on Bantarjati Village, Kelapa Nunggal Sub-District, Bogor District, West Java Province. The MHPP planning first starts by analyzing the hydrology to get the flood discharge plan and dependable discharge. Structure planning for MHPP includes weir planning, intake building, settling basin, penstock, and power house. With 205 km2 total area of non-ground water in Bekasi watershed, Cileungsi River has a 962.30 m3/second flood discharge plan with 50 years repeating period and 2,5 m3/second dependable discharge. Power plant has a weir to elevate water level with 43.2 m effective width and 10 m crest height. This MHPP has 10 m head fall height and generates electricity 154.22 kwH with one turbine.

Abstract

Flood happened recently is already a thing happened each time in various regions in Indonesia, not least in Semarang, especially in the area Mangkang. Improved function of the weir Plumbon previously only built for irrigation becomes a flood control dam is expected to reduce or cope with floods that occur each year in these areas. Plumbon river has a total length of 14.123 km with the average slope of the river (i) 0.0165. Plumbon watershed has an area of 20.36 km2. Planning weir Plumbon increased functionality using rainfall data of the last 12 years (2002 - 2014) with 3 stations namely rain Middle Reef (33F), Mangkang Reservoir (41C), Kaligading (20). Calculation of flood discharge plan obtained with a return period of 20 years (Q20) of 365.015 m³ / s with HSS method Gama I. Enhanced functions for flood control is done by raising the dam height lighthouse, so the catchment area will increase and may decrease the discharge passing through the dam , Plumbon weir using high lighthouse beacon round with 8 m wide and 17 m effective. Plumbon weir is planned to advance along the floor of 9.0 m and use a pool megrim with length of 16.5 m with a thickness of 2.5 m pool floor megrim selected while the pool is the type USBR type III.
