Abstract

Progopistan Weir is fix weir for irrigation necessary, it had built on Progo River, with area flow of river is 70,116 km2, it is location on Gemawang District, Temanggung Residency in Central Java special territory. Progo River watershed in the region especially those in Gemawang District, Kandangan district, Kaloran District, Kedu District, Temanggung Residency in Central Java there is still rain-fed agriculture. In its development, the availability of irrigation water to irrigate the area is considered very less, so that people suggested that services can be improved through the development of irrigation dam which can reach all areas. Before the dam was first planned analysis so unknown flood discharge for the return period of 50 years was 234.64 m3, and Debit retrieval of 2.42 m3/second. Progopistan weir will design with specific, such as ogee summit 6,3 m tall, USBR type III for Stilling Basin and also completed with sand trap. Canal for slice, gate for intake and slice and Retaining walls. Progopistan weir spend of fund around Rp. 6,9 billion and time schedule for construction around 196 working days.

Abstract

The land degradation of Cimuntur Sub Watershed that happened causing the function of sub watershed is changing as a basin. The indication of erosion and sedimentation was 88,55 ton/ha/yr and sediment yield was 0,91 mm/yr. Therefore it needs study to figure out how big is the erotion and sedimentatiom in Cimuntur Sub Watershed so that can get the solution for the problem which happened in Cimuntur Sub Watershed. Analizing of erotion and sedimentation in Cimuntur Watershed is used Universal Soil Loss Equation (USLE) Method and is helped with ArcGIS software. ArcGIS software is used to overlay datas. The input data which is needed for USLE Method is Rain Erosivity Factor (R), Soil Erodibility Factor (K), Slope Length Factor (LS), Land Use Factor (C), and Practical Conservation Factor (P). The result of data overlay by ArcGIS is erotion happened. From the analizing datas is gotten that erotion at Cimuntur Sub Watershed is 963,747 ton/ha/year and sediment yield is 14,649 ton/ha/year. And then making classification of erotion class. This erotion class is made to be used as the consideration base for defining the alternative solution will be done and determine location of erotion and sedimentation solution. The alternative erotion and sedimentation solution of Cimuntur Watershed is done by doing conservation such as vegetative conservation or mechanical conservation. Vegetative conservation can be done by improving the land use management. After doing vegetative conservation, erotion decreases to 237,415 ton/ha/yr and sediment yield 3,61 ton/ha/yr. Whereas mechanical conservation can be done by building a sediment contoller (check dam). Check dam construction is done at big erosion category that is Cirende River with capacity is 8945,95 m3.

Abstract

Flood is one of the disaster which often happened in Semarang city. Many negative impact arising from flood disaster, such as loss of victim or material. One of the handling solution is  developed flood shelter. Some region of Semarang cityhave own flood shelter, so in this case we need to identify of elegibility and improvement. Identification location of flood shelter are in Beringin Watershed Semarang which consists of 6 Kelurahan, namely Kelurahan Wates, Kelurahan Wonosari, Kelurahan Mangunharjo, Kelurahan Mangkang Wetan, Kelurahan Gondorio, and Kelurahan Beringin. Data obtained from the field survey,with existing data of flood shelter that has been there. Sources of criteria for  flood shelter location are sphere project handbook, 2011, Health Minister’s decision on the minimum sandart of health problems caused by disaster prevention and handling of refugees, and egulations of BPBD. Some regions like Sub-District of Wonosari require a building in the form of House Podium and emergency doorstep. Because the location have bank- bank resulting the pursuing of evacuating and handling. Besides, some shelter pitched a tent of the size according to requirement to accomodate lacking of room for refugee in shelter. But, people arround the riverbanks should keep the environment clean and not littering, so can decrease the impact of flood.
