Abstract

Floods are natural disasters that regularly occur in DAS Lusi during the rainy season. Reduced water catchment areas in the upstream area of the river is one of the causes of increased flood discharge in river Lusi. Attempts to reduce it is to plan long storage system, a building that utilizes water as a resevoir riverwith weir building in the downstream.Long storage will be built on the upstream of the Lusi, located at Jetis, Kecamatan Blora, Kabupaten Blora. The purpose of the construction of long storage Jetis is a flood control system and as a resevoir for the surrounding areas. From the result of rainfall data in Blora, Jiken, Jepon, Bogorejo and Tempuran station, return period of 25 years Q25 = 242.059 m3 / sec are used to analyze the capacity of the river and weir stability. While the discharge is used in analyzing the resevoir using a debit andalan based formula FJ Mock with large long storage bin is 42 liters / sec.Plan development time required was 12 weeks with a total budget of Rp. 12,852,198,000.00. (Twelve billion eight hundred and fifty-two million one hundred ninety eight thousand rupiah).

Abstract

In 1992, Kaligending Weir was Built at Kaligending Village, Karangsambung District in Kebumen. In 1998 the Kaligending Weir was dismantled due to the flood at Karangsambung which the people considered was caused by the weir. this made the water unable to enter the intake and made the Irigated area not being supplied by the water from Kaligending Weir. The Kaligending Weir is located on non groundwater area. At non-Groundwater basin, water flows only on the soil water zone, meanwhile at groundwater basin, there are water flow in the ground water zone layer. Calculating the water availability is needed to fulfill the irigated water demand. Water availability is calculated using modified F.J. Mock Method. Kaligending Weir was constructed at Luk Ulo River with a 253,52 km2 basin area and 2984 Ha irrigated area. Kaligending Weir is planned by using 1361,19 m3/s flood discharge with a 50 years period calculated by FSR JAWA SUMATERA method. Kaligending Weir uses a 3,7 tall round crest. The stilling basin is 39 m long and 7,72 m wide. By considering the volume and unit price, Kaligending Weir cost Rp. 133,796,306,000.

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.
