Generally, wind energy sources in Indonesia's coastal areas is one of the potential sources of renewable energy (renewable energy resources) which are abundant, environmentally friendly and renewable. Savonius wind turbines can produce relatively high torque even at low wind speeds. Because it is very well developed to produce electrical energy. To get a large electric power, a large turbine construction is also needed which also certainly requires a large cost. For this reason, it is necessary to develop the dimensions of this wind turbine construction which is known as aspect ratio (Ar). The Ar that has been researched is the blade section, and other values. While the arch depth or the length of the blade arc in U -type is still likely to be researched. Therefore, it is necessary to do research on the U-type blade arc to get greater power than before. In addition to the experimental method with a prototype of the U type Savonius wind turbine with a number of 2 blades, a software-based simulation method will be carried out to analyze the air flow on the wind turbine blade. Parameters varied only with the aspect ratio of the arc length and blade cross section width, other parameters follow the previous research. This analysis will be a comparative data with experimental methods. The expected simulation results obtain the best aspect ratio (Ar) blade in capturing wind energy.

One of great potential area in the fisheries sector in West Java province is Indramayu District. Percentage of fisheries production which accounts for 60% of the needs of the fishery. Indramayu community, especially the northern coastal areas of Indramayu district of livelihood relies heavily on the this sector. During this process the dried fish production still relies on the natural conditions of the solar thermal. So that when the rainy season the fishermen feel a loss, because of natural heating hampered and finally ignored orders from customers due to the and declining fish quality, so prices soaring sales doubled. Hence, the need for attention to improving the quality of production of dry fish processing, is one of the way by utilizing the split Air Conditioning (AC) as a heating dehumidifier for drying fish. This equipment is modified by utilizing the waste heat from the condenser as reheat is then added to the electric heater is controlled according to the needs drying, and after that it was blown with using fan/blower to the drying chamber containing the fish on the shelves are arranged. The results obtained can be analyzed on the performance, drying temperature and relative humidity (RH) or water content is as expected.
