Abstract

Town in veri dynamic area. Growth of populatio, both natural and  migration (urbanization), need area for the settlement and their activities. Neccesity of area for settlement can’t be avoided. As a result, there is a landuse changing from non settlement area (set field, dry field, swamp, pond) to settlement area. This change will influence the hydro system balance in Semarang, for instance the extending of flooding area, etc. This research tries to find the characteristi of landuse change in Semarang. The characteristic involving how is pattern, process, intensity, and tendency. Pattern of landuse changing is sequence of using area before it became the settlement. Process of landuse change is by using the population are able to settle. Tendency is degree of landuse change speed. This research methods secondary analysis method, that is compare the statistic data of the landuse and map in 1980 and 2000. The sampling is by purposive random sampling method. Purposive is used so that all subdistricts in sub urban are represented. The sample area is the from percil in ertain coordinate. Result of this research shows that there is landuse changing rapidly that is decrease in the width of wet field, dry field, swamp, and pond. On the other hand, there is increase in width of settlement area and other dry land with intensity 232 ha every years. Wet field decrease 131,7 ha every years, swamp and pond 31 ha, and dry field 24,2 ha every years. In actually this landuse changing pattern is out of government policy. Semarang conversed. However, wet field is water habitat that is most potential. Tendency of sttlement growth is more facus on accesibility aspect and available city’s facilities only. Number of settlement are built on land which not suitable, such labile land, or high slope. It proves that the government control function is weak. The conclusion from this research that landuse changing has to be ontrolled restrainded, so it will not cause the bad effet in Semarang. Width the wet field is 10% by width town, must be conservation. Because wet field has ecology value and economic value that is rice production and absorb labour in agricultural sector. Therefore, function role of government controll must be actived.

Abstract

The aim of the research are to measure the type of mass movement and landslide hazard zoning for settlement ite evaluation. Terrain unit and their characteristics are the main inputs. Terrain classification based on genetic, morphology, and lithology are important aspects in the mapping of terrain through aerial photo interpretation at scale 1 : 50.000. Sampling method is stratified random sampling. Data considered in this research consist of slope, soils, lithology, dissetion, lineament, land use, vegetation, morphometry of landslide. Laboratory analysis is done for soil physics determination. Scoring and addition method are applied in the landslide hazard zoning through GIS programme. The result of this research are that structural – denudational mountain unit shows highly landslide hazard with sil/debris slide, planar block slide as dominant processes, while in the structural – denudational hills and colluvial valley bottom and river terraces show moderately landslide hazard with soil/debris slide and soil creep as main processes and then in the peneplain and colluvial slope show low landslide hazard. The highly landslide hazard zone cover settlement at the area Krempong, Sucen, Karangseneng, Kedawung, and Margalelo.

Abstract

In 2000, the area of DAS critical land in Indonesia is approximately 23,242,881 ha which consists of forest area 8,136,646 ha (35%) and non forest area 15,106,234 ha (65%). In the contrary, the fact shows that in 1989/ 1990 (the beginning of ‘Pelita’/ the five years development planning owned by the government), the area of DAS critical land in Indonesia was 13,180,000 ha only that consists of forest area 5,910,000 ha and non forest area 7,270,000 ha. The cause and its location of negative improvement of the above DAS has not been predited yet. The one of the causes is the weakness of information system on very DAS management system in the aspect of biophysical, soial, eonomical, and cultural. Therefore, it needs the improvement of DAS management which is supported by the result of research and development. The purpose of this research is to get the potency information and the possibility of sensitivity of the land resources in the frame of DAS management with biophisical land as the parameter. Sub DAS of Merawu (21,860 Ha) isas one of the parts of ‘bulu’ DAS Serayu with stream flow minimum 0,81 m3/second and maximum 108 m3/second. The sub DAS of Merawu as the part of ‘bulu’ Serayu has the type of climate A and B with annual rainfall approximatelly >2,000 mm and it can support everything in the stream flow of in order to prevent the flood. This ondition is caused by the permanent vegetation such as forest, underbrsuh or srub, tea garden, as well as multi – plantgarden that has around 40% happen in the ineptisol land, although precipitous slope and very precipitous (>25%). The technique of land conversation is good enough in its development, mainly in the dry section of the field by using ‘teras gundul’ and ‘teras bangku’ the society near Sub DAS of Merawu is densely populated, its is around 517 up to 827 persons/ square with their main profession as farmer and their income is around Rp 2.000.000 per year. Bya analysing the above DAS management, it an show that sub DAS of Merawu has the potency of water both for internal and external DAS consuming. The potency of using the land for farimng one season in length (class II, III, and IV) consists of around 50,8%. The development multy plant garden (25% area of DAS) is as the type of potential farming effort because of the diversity of both the result and time; besides it is also as the form of protection toward the effetive land. The possibility of sensitivity is too wide land which is susceptible toward the slide (land slide), mainly in the middle part of the DAS. The live dependee of land which strong enough is as the threat toward the future resoures conservation.

Abstract

The researh is carried out at the basi pillar in Surakarta that is estimated has a clear different at ground water quality. The goals of the research area 1) to know actually the distribution of arial zoning at pollution level of the groundwater; 2) to determine the priority scale of clean water supply. Data analysis used in the researh are tendentious analysis and geographical information system. The result shows that groundwater quality at the research place decreases. It can be proved by tendentious analysis that most of the groundwater quality conentration parameter – after being examined – the lower plae, the higher conentration. There are 21 quality parameters used for that research, 15 out of those have an inclining tendency, while the others are flat and decline. The result of 2 overlapping maps, atual zoning and potential zoning, shows that there is mismatching of risky polluted area. It is caused by human fators, some of them are population density, well construction, bad sanitation, individual septi tank, and industrial disposal from irrigation. Based on the result of the research, clean water district corporation is expected to be able to determine priority scale of clean water supply to Surakarta and its surrounding.

Abstract

The objectives of this research were 1) to determine soil moisture regime based on rainfall and temperature data; 2) to make a correction of the first objective based on soil moisture surplus and deficit calulation; 3) to study the pattern of soil moisture regime distribution in the research area. The field sampling tehniques applied in this research was stratified proposed sampling. Landform unit was applied as strata. Soil depth and texture were considered during field soil sampling within the landform unit. Rainfall and air temperature data were analyzed using Newball Simulation Model (NSM) to determine a tentative soil moisture regime. The tentative soil moisture regime was corrected using calculation soil moisture regime of soil moisture surplus and deficit. The soil moisture surplus and deficit was calculated based on soil depth, soil texture, rainfall, and temperature data. The result of this research were 1) soil moisture regime estimated using NSM ranged from ustic to udic; 2) soil moisture regime corrected using surplus and/ or defiit alulation of soil moisture ranged from xeric to udic; 3) the pattern of soil moisture regime distribution in the reaserch area was not only controlled by the pattern of rainfall – air temperature distribution but it was also controlled by the pattern of soil – landform distribution. Under the some amount of annual rainfall, shallow and coarse texture soils have drier soil moisture regime than deep and fine texture soils.

Abstract

There are two objectives of this researh. First, to identify and analyze the condition of ground water quality in the research area, and second to determined the chemial types of groundwater. To ahieve these objectives 59 groundwater samples were taken stratifiedly, base on the different of electrical conductance value. As a result, it is identified that most groundwater in the research area is not suitable for drinking water sources, because has high concentration of electrical conductance, turbidity, hardness, chloride, manganese, and salinity. Thiis conclusion is also supported by stiff diagram analysis. The result of Stuyfzand analysis shhows that the chemical types of groundwater is very variative. Groundwater in coastal areas has higher suply of saline water than fresh water.
