Tegal Regency Consists of 18 Sub districts, 287 villages, and 1.499.167 populations (2010). From the population above, most of them are located in village area which is spread in all sub districts. Topography in Tegal is 87.879 Ha or 878,79 Km 2 with declivity land between 0% until 40%. Based on discharge in river and irrigation channel its head, it estimated that there is microhydro potential can be generated as an alternative solution of electricity problem. This researchis aimed to analyze river and irrigation channel potential for PLTMh, plan the crossflow turbine, and design potential located of PLTMh which is chosen (Baturgedong-Danawarih). To determine the microhydro, the research has been done toward discharge river data, rainfall, topography map, administration map. Primary data collected by direct measuring in the area, like irrigation channel discharge and head. The research result of water energy potential in Tegal Regency is obtained 1012 KW electricity power in 9 potenial points from irrigation cannel and 539,495 KW from 12 potenial points in the river. Its total is 1.551,553 KW, Economy analysis result indicates investment cost which is needed by development of microhydro power plant (PLTMH) system at�gung� primary irrigation channel Baturgedong is Rp.824.000.242,00- with Benefit Cost Ratio ( BCR ) = 1,87. The construction result of crossflow turbine which diameter 88 mm, for head = 3,4 m and Q = 5 lt /s, the result of efficiency is 59 % .
