| The hot water is needed by everyone, both for bathing and washing. One of the alternative energy is solar energy, which can replace fossil energy to heat water. To obtain solar water heaters are economical, system optimization analysis on the thermal water heating systems are indispensable for the production cost can be reduced, especially collectors. So get a cheap price in the manufacture of heating systems and hot water to get the maximum. Volume of this collector is 25 liters. Optimization calculation used is to use linear programming, the function of minimizing the cost of manufacture of flat plate solar collector types. Barriers are used to the heat generated by solar collectors. To calculate the linear program optimization with the aid of lindo program. From the calculation results of optimization of thermal systems by comparing the prices collectors of type X, the price collector to the sun is more expensive than the price collectors are facing the sun. Price optimum solar collector type of X is Rp 1.406.000,00 while the price collectors are used in the final project is Rp 3.317.500,00. This happens because the solar collector to the sun is less optimum placement, so that the sunlight that falls into the collector can not be absorbed in a maximum. But from the water heater system keseluranan used in this thesis with the cheaper price of Rp 8.688.000,00 while the water heater type X Rp 11,550,000.00. |
