Utilization of Tidal Land of The Wonogiri Reservoir
No full textManagement of water dam often failures due to the limited attention to the socio-economic activities of the local population. This research is conerned with agricultural land utilization practiced by the local inhabitants in the vicinity of the dam. Special attention is devoted to characteristics and motivation of the farming households, the way in which lands are utilized, as well as the contribution of the activities to the welfare of the households. The research combines secondary data analysis and a household survey. Primary data are collected via a household survey covering a sample of 150 households cultivating the draw down land of the dam. These households are taken by a simple random sampling, representing some 5,890 hhouseholds living in the vicinity of the dam. Data analysis are executed using various statistical techniques in order to test differences and correlation.The study reveals that the tidal areas of the Wonogiri Dam fluctuate from 1,300 to 6,400 hectares, within 1 to 7 moths period per annum. The cultivator of the tidal area consist of the farmer inhabitants of the dam prior to the construction (81,3 percent) and inhabitants of the surrounding areas of the dam and new omers from other areas (18,7 percent). These farming households are pushed to cultivate these lands due to limited control over land resources in their areas of origin ( averaged 1,057 m2). Variations in the areas of origin and motivation in utilizing of the lands do not lead to significant differences in the size of land cultivated in the tidal areas. Most of these lands are devoted to ultivate rice as staple food (1,470 m2), rather than to cultivate cash crops (palawija) (1,118 m2). Farming techniques employed in these areas are much more simple than those prior to the construction of the dam or those elsewhere at present in the district. The most important factor affecting incomes in this activity is the amount of capital cost spent. These incomes comprises some 60 percent of the farming households
Introduction of Alley Cropping
No full textOne of the efforts to preserve the sources of vegetarian, soil, and water is to rehabilitate the land and soil conservation. The aim of this rehabilitation is increasing and maintaining the produtivity of the land, so it can be preserved and used optimally. Therefore, it is necessary to a develop a variety of good soil conservation, such as vegetative method and civil engineering. To find an appropriate technology, so it is necessary to develop some alternatives of soil conservation technique that are mainly implemented at dry land with its slope of more than 15% in the upstream area of discharge. One of the most suitable soil conservation technique today is Alley Cropping. Based on the research (trial and error) in some areas, Alley Cropping could really provide a positive result in terms of erotion controlling and running off and maintain the land productivity. In addition, the technique is more easly operated and spends a cheaper cost than making a bench terrace

Perkembangan Daerah Perkotaan Ditinjau dari Aspek Hidrologi
No full textPerkembangan daerah kota secara fisik ditandai dengan meluasnya wilayah kota dan bertambahnya daerah permukiman baru di sekitarnya. Di sisi lain perkembangan kota menyebabkan dampak negatif pada kondisi hidrologi, baik yang kuantitas maupun kualitas. Perluaasan daerah kota sering menyebabkan banjir dan genangan di daerah kota itu sendiri, yang disebabkan oleh meningkatnya koefisien aliran serta tidak mempunyai saluran drainase untuk menampung limpasan yang terjadi. Perkembangan kota menyebabkan kebutuhan air meningkat untuk penyediaan air di daerah kota tersebut. Air yang digunakan berasal dari berbagai sumber air, baik air permukaan maupun airtanah, yang sifatnya terbatas. Aktivitas penduduk kota menghasilkan limbah yang dibuang ke dalam lingkungan, yang dapat menemari air permukaan maupun airtanah. Di pihak lain airtanah masih merupakan sumber yang utama untuk penyediaan air di daerah kota. Perkembangan daerah kota dapat mempengaruhi kondisi hidrologi baik kuantitas dan kualitasnya, yang hal ini dapat dijadikan pertimbangan dalam perkembangan dan pengembangan kota
