Abstrack:
Natural disasters always pose problems for humans and the environment. In the unusual natural conditions such as floods, devastating earthquakes, volcanic eruptions, clean water to its own problems for humans. The earthquake and tsunami in Aceh on 2004 and earthquake in Yogyakarta on 2006 are the clear example of environmental damage caused by natural cause an emergency situation. The purpose of this research include generating appropriate technologies, such as water purification equipment with mechanical energy to provide clean water in an emergency, produces environmentally friendly technologies as an effort to improve the development environment (sustainability development). This study is divided into two phase, the first phase is the generation of electric power. The 12 Volt dynamos are driven by a paddle wheel bike R.30, to fill accumulator 12 Volt DC after rectified with Diode Bridge. Accumulator is used as a driving force of water pump after invertu singin verter 12 Volt DC-AC. The second phase is water purification device. The first serves as a coagulation box has a filter Bioform 4cm. The second box serves as achlorination by 4cm Bioform filter and charcoal, while the third has a filter Bioform 4cm and charcoal serves as a water tank. Coagulant dose ratioused 0.50 grams / literalum, 0.1grams/liter of limes tone with a contact time of 1 hour, while the chlorination process using a dose of 0.05grams/liter of chlorine. For 5 minutes. Sample data collected from several rivers flowing in the region of Yogyakarta province. The parameters tested include Total Suspended Solids (TSS), Turbidity (NTU), the content ofiron (Fe), manganese content (Mn), Sulfate (SO4), Degree of acidity (pH) and Total Coliform. Results of samples tested at Health Laboratory Yogyakarta. Mechanical water purification technology using a bicycle wheel radius (R) 30 cm equipped 12 Volt dynamo as a source of electrical energy, Diode Bridge 1 Ampere, the accumulator 12 Volt 5 Ah, 12 Volt Inverter DC-AC, 16 Watt mini water pump as well as a series of coagulation bath, chlorination and water tank is equipped bioform 4 cm and charcoal, can be used effectively for the provision of clean water in an emergency. Coagulant dose ratio of 0.50 gram / liter alum, 0.1 grams / liter of limestone and 0.05 grams / liter of chlorine can lower water levels on the parameters TSS (Total Suspended Solid), Turbidity (Ntu), Iron (Fe), manganese (Mn), pH and Total Coliform in accordance with the water quality standards required.
