PERENCANAAN SABO DAM KALI PUTIH (KM 16,7) KABUPATEN MAGELANG JAWA TENGAH
ABSTRACT: Mount Merapi (2980)
meters above sea level), one of the most active volcanoes in the world, located
in Central Java Province. Mt. Merapi last erupted in 2012, producing a large
number of volcanic materials which has highly destructive force. This flow
happened on almost all of the rivers in Mt. Merapi hillside, such as Kali Putih
for example. Kali Putih has a big potential of damage because of its location,
near rural areas. Reffering to the above mentioned, the preventive effort of
disasterous effect need to be done to decrease the damages by using Sabo Dam.
The data we need to design it are hydrological data such as annual daily
rainfalls data and Kali Putih catchment area map, soil investigation data, a
topographic map and geometric river map. Those data will be processed and used
as the basis for designing the Main Sabo Dam, Sub Sabo Dam, Apron and etc. The
results of Sabo Dam design are: total height of Main Dam is 8,55 meters, total
height of Sub Sabo Dam is 2,79 meters,
length of Apron is 6,1 meters, sediment storage capacity is 8.100 m3, the total
cost is Rp.1.470.615.000,00 (including VAT) and the construction phase is 14
weeks. The construction of Sabo Dam will be more optimal if it is accompanied
by a good maintenance system done by the related agencies, so that the
percentage of the damaged covering areas will decrease significantly.
