Abstract

Bengawan Solo river flow changes is estimated to occur about 2 or at least a million years ago. The image interpretation results obtained ancient Bengawan Solo river which has become a valley winding naturally potential to be flood-prone areas. The aim of this study is to asses the condition of morphology and morphostructure of River Bengawan Solo and the impact towards flood overflow. This research use survey method. Data analyzed by quantitative descriptive technique, assisted with GIS analysis. The results of this study are (a) the morphology of the present; positive skewed figures means that the material is the result of fluvial processes and susceptible to flood overflow. The direction of the flow is toward the North, to the North Coast of Java which is lower, (b) morphostructure at the present; Solo River water level leads to the North, but at a certain point, there are seen places which are uphill or places which are higher than before, which are must lower for a uphill or a higher place than before, which are should be lower. This cause the tilt to rise. Silting and erosion occurs at a certain point. Point 11-18 are the point that be the impact of streamlining river, so its flow getting swift. At some point (between 11-18) it seem very close the distance between the water height and the ground level, means that the water height close to the height of the surface, so that leaving it vulnerable to flood overflow. This condition is particularly worrying in case of rain with a large quantity of water that will be up and overflow onto the surface. At point 11, 13, and 16 clear to see that the river is very shallow if it is compared to other points.Keywords: morphology, morphostructure, Flood Overflow, Watersheed

Abstract

The aim of this research is to create a disaster evacuation paths based on the results of flood modeling. The method used in this research is least cost path. The results obtained from this study were (a) the impact of a simulation model to land use is the buildings area 885,36 m2, water area 10.621,97 m2, vacant land with rare vegetation area 68.916,64 m2, vacant land with vegetation area 78.925,16 m2, and settlement area 137.251,78 m2, and (b) evacuation paths produced by the method of least cost path is two lanes in Kampung Sewu and 2 lanes in the village of Jebres. The least cost path choose lane from the first starting point in intersection of three road of Beton and go accros Gotong Royong road to evacuation point in Jami’Mosque. Both of the starting point in the Bengawan Solo river embankment can to the evacuation point Sawunggaling Mosque. Jebres evacuation route in the village there are two lines of evacuation. The first lane evacuation from the starting point in intersection three road of Kentingan to the front Psychiatric Hospital Surakarta, and then to the front office Psychotherapy Center Surakarta North toward straight up in Al-Fath Mosque. Both are alternative evacuation route from the starting point in a four-way intersection in the middle of densely populated settlements can pass the road to the west to get stuck, then straight over the bridge, past the front of the Student Dormitory UNS, then to the evacuation site Al-Fath Mosque.Keywords: simulation model, evacuation route, GIS

Abstract

Groundwater is a natural resource that must be managed and preserved well. Monitoring of groundwater quality essential as vulnerable ground water pollution, so the quality is declining, which in turn can not be used for domestic and non-domestic purposes. The aim of this study is to analyze the quality of groundwater in the volcanic slope of district Klaten, Central Java. The research method that used is survey. The analysis of the results based on the quality standard ofdrinking water in accordance PERMENKES No. 907/Menkes/SK/VII/2002. The data which collected are land form, shallow groundwater data, groundwater pressure, and springs. The results were obtained: (1) the landforms in Klaten are divided into four units, namely slopes and volcanic peaks, volcanic foot, volcanic fluvial plains, and a structural, (2) the quality of shallow groundwater in Klaten is under the standard that is set by PERMENKES No. 907/Menkes/SK/VII/2002 or it can be consumed.Keywords: groundwater quality, land form, volcanic slope, Consumption
