ABSTRACT

Gunungkidul is mountainous and drought-prone areas. These conditionscause some areas had difficulties of water supply . As the main body needs toperform metabolism and maintain a healthy body the water intake must besufficient.

PDAM as the water service provider for the community requires atechnology that can produce energy, so that the water from low-lying areas canbe lifted to higher areas. In the development of Micro Hydro Power Electric(Pembangkit Listrik Tenaga Mikro Hidro /PLTMH ) is not only meet theneeds of electrical and lighting. The system can be part of a clean watersystem supplier for the community.

This study was aimed to conduct a feasibility study, planning, design andmanufacturing of installation system of laboratory testing. The results of thisstudy are expected to produce method as an effort to raise water from the lowerto the higher area.

The study started with the collection of secondary data and primary datathrough surveys, discharge (Q) measurements, the potential Head (H)measurements, Feasibility Study, planning, turbine design manufacturing andcivil buildings design.

Turbines used in the study was cross flow turbine with blade number of24 pieces, in earlier tests with the Head of 2.9 m produces the characteristics ofQ = 40 Vs, Pout = 593.94 watts , N = 1273 rpm and rl = 96 % .

Testing laboratory model system using the penstock installation of 4inches PVC pipe, and Head of 4 m , with a working pump system or Pump AsTurbine ( PAT ), resulted in the characteristics of Q in = 20 1/s , N turbine of646 rpm and rl = 98.9% and was able to lift water up to 7.5 m.
