Abstract

Beton karst spring is located in the Ponjong sub District Gunungkidul Regency, at thewestern part of Bribin undergorund river catchment area. The purpose of this study are: 1) toknow the variations of rainfall and discharge in the research area, 2) to know thecharacteristics of the physical water quality of Beton spring and 3) to determine therelationship between the variations of the rainfall toward the discharge and the physicalwater quality of Beton spring. This study uses survey methods and the techniques of datacollection using sample by purposive sampling. The variables are rainfall (the depth andintensity), spring discharge and physical water quality of spring (EC, T, TDS, turbidity). Thedata analysis is conducted graphically and descriptively to explain the relationship betweenthe variations of rainfall to the discharge and physical water quality of spring. The resultsshow the rainfall has variations include the pattern, events and the amount of rainfall. Betonspring has high discharge variations. The physical water quality of the spring meets to thewater quality standards according to the Government Regulation number 82 years 2001. Thestrong correlation between rainfall variations to the discharge and the physical water qualityof Beton spring can be seen clearly. It is reflected from the high value of R2.

Abstract

This study deals with the evaluation of surficial material characteristics, based on landform units in the Serang River Basin. The approach concentrates on the use of geomorphological mapping by using aerial photo interpretation and field investigations. The landform units, as defined by geomorphological mapping, was used as sample areas to determine the surficial material characteristics. These characteristics include grain size, sphericity and roundness coefficient. The measurement of the material characteristics in the river bed was based on 100 gravel pebbles systematically sampled along the length profile of the river. During the survey, 14 cross sections were chosen. The potential of the alluvial material resources was estimated by their areal distribution, thichness sedimentary and characteristics.Among landform units in the studied area which contains a large amount of the materials are: natural levees, river terraces, river bed and hill foot slopes. Generally, the river bed materials decrease in grain size downstreams and increase in sphericity and roundness coefficient. In some cross sections a reversal was found to the general tendency. This situation might be due to human activities for getting material for construction. Due to human activities some environmental impacts occur.

Abstract

The research carried out in alo-pohu watershed gorontalo province aims atidentifying the effect of watershed conditions and land use on the amount sheeterosion, sediment yield and sediment delivery ratio. It is also intended to developthem in a spatio-temporal distribution, and give recommendation for managementof environmental condition and land use in alo-pohu watershed to prevent damageerosion and sediment. Data on environmental condition and land use werecollected by interpreting landsat images and topography map. Data on surfaceerosion were obtained by means of direct measurement using 10 erosion plotsplaced in the land units. Data on sediment were obtained by collecting watersamplesfrom the upper course, middle course, and lower course of the rivers. Dataon sheet erosion and.sediment yield were analyzed in a spatio-temporal mannerusing geographic information systems (gis) and effect of watershed conditions andland utilization on sheet erosion, sediment yield, and sediment delivery ratio aretested using double regression analysis. The research results suggest significanteffect of watershed conditions and land use on sheet erosion. the largest amount oferosion very likely occurred in wasteland (bero land) with steep slopes whereas theleast amount of erosion was found in undergrowth with flat slope (0-8%). theamount of sheet erosion was 122.24 ton/ha/year. sediment yield in alo-pohu wasaffected to a large extent by runoff rate, the width of watershed, percentage ofwasteland, and drainage density.

Abstract

Geomorphologial approach can be used as the basic for identifying and analyzing the natural resources potentials, especially in volcanic landscape. Based on its geomorphology, Merapi volcanic landscape can be divided into 5 morphological units, i.e.: volcanic cone, volcanic slope, volcanic foot, volcanic foot plain, and fluvio-volcanic plain. Each of these morphological units has specific characteristic and natural resources potential. Based on the condition of geomorphology, the regional zoning can be compiled to support the land use planning and to maintain the conservation of environmental function in the Merapi Volcanic area.

Abstract

Transmigration is one of the manifestations of artificial human community that is expected to increase thenatural resource utilization activities for welfare in a transmigration location. This paper is to find out the livelihoodstrategies and their effect on transmigrants’ welfare. Results of the study indicates at Stage I (the first 1.5 years), transmigrantsgenerally applied a survival strategy by relying on the living allotment of government. At Stage II (the second1.5 years), a part of them sougth other source of income for establishing their livelihood. At Stage III (the third 2 yearsand afterward), a part of them left the transmigration location, while others have able to survive until the primary commodityof rubber can be productive after the sixth year of cultivation. Welfare is achieved by those that could to applythe livelihood strategies to have the established sources of income outside the transmigrants’ primary commodity, particularlyfrom Pasuruan, East Java Province.
