| Summary: | 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 is a really
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 sustainable development.
This study is divided into two phase, the first phase is the generation of
electric power to drive the mini water pump. 12 Volt dynamo driven by a paddle
wheel bike R.30, to fill accumulator 12 Volt DC after rectified with Diode Bridge
1 Ampere. Accumulator is used as the driving force of mini water pump after
rectified using inverter 12 Volt DC-AC. The second phase is design and
manufacture of water purification equipment. The first serves as a coagulation box
has a filter Biofoam 4 cm. The second box serves as a chlorination by 4 cm
Biofoam filter and charcoal, while the third has a filter Biofoam 4 cm and
charcoal serves as a water tank. Coagulant dose ratio used 0.50 grams / liter alum,
0.1 grams / liter of limestone with a contact time of 1 hour, while the chlorination
process using a dose of 0.05 grams / 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 of iron (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 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.
