Abstract

Ampelgading hydropower is a long-term program of PT. PLN (Persero) Parent Project Pikitring East Java and East Nusa Tenggara Section Wonorejo Hydroelectric Project, in order to find a cheap electricity prices and utilization of water semberdaya, then Ampelgading areas deemed suitable for the use of water resources Water Power Plant. Location of development planning Hydroelectric Power Plant (HEPP) is located in Malang Regency which is located between 112 ° 54 '32.28 ˝ East Longitude and 8 ° 15' 42.62 "South latitude, exactly at the Duck River Resources, Tawangsari Hamlet, Village Tirtomarto and the River Andengan, Pucungsari Hamlet, Village Purwoharjo Ampelgading District located at ± 75 km in the city of Malang. From the highway department Malang-Lumajang to the location of the project through the village road in the form of macadam road with a width of approximately 5 m as far as ± 5 km up to the location of ponds. A condition to achieve the minimum cost with the benefit of as much as possible, called optimization. Penstock pipe is a pipe tap that is used to drain water from the tank top (head tanks) or directly from shooting to the turbine building. Penstock functions designed to withstand the pressure blows the water (water hammer) caused by the result of the turbine valve is closed abruptly. From the calculation, it is obtained that the larger diameter pipe, the greater the investment costs and annual fees. energy loss is strongly influenced by the diameter, with a smaller diameter then the cost of energy loss will be even greater. Regression model estimates for Non-Linear Regression Model cubic parabola obtained the optimum diameter of 1.493 m ~ 1.5 m and a minimum total cost (annual fees and costs of energy loss) of Rp. 11,819,194,030 ~ Rp.12.507.283.914.
