Abstract

This research was carried out in Sumbawa island, it aims to determine: 1) the value of Snyder’s CT and CP coefficient of the synthetic unit hydrograph; 2) the empirical model to estimate of CT and CP coefficient; 3) the empirical model to estimate the peak flow and time lag of synthetic unit hydrograph. Based on rainfall – runoff data, Snyder’s T and CP coefficient of the synthetic unit hydrograph can be derived by syntheti means. The empirical model of CT and CP coefficient can be estimated by using the stepwise method of the multiple regression models. Measurable characteristics of watershed, including watershed area (LDP), length of main river (PSU), slope of watershed (KIM), forest area (LHT), sawah area (LSW), tegal area (LTG), grass area (LRUM), and mean annual rainfall (CHJ) are used to estimate these model. The most appropriate model is selected from a statistical test. Result of analysis show that the model can be used to estimate of Snyder’s CT and CP coefficient. These model can be used to make the empirical model to estimate the peak flow and time lag of synthetic unit hydrograph of ungauged watershed in Sumbawa island.

Abstract

Management  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.

Abstract

The objetive of this research were conducted in Kulon Progo Regency were to know how far utilization of farm technology (hand tracctor, tresher, benguk arver, and cassava rapier) will inreasing income farmer and works diversification on different topography and accesibility. The data included primary and secondary data. The primary data were collected from respondents by filling questionnaires, while the seondary data were collected from the governmental officer. Region samples are Lendah sub regency which low land plain area, Sentolo sub regency which hilly area, and Kalibawang  sub regency which mountain range area. Respondents sample was taken by snow ball sampling, who utilized of farm technology and they are 58 respondents from low land plain area, 38 respondents from hilly area, and 38 respondents from mountai range area. The data were processed by using computer, while hypothesis was tested by crosstab and hi quadrate to compare result of research in the three different topography areas. The result of the research shows that there are difference significant utilization of farm technology aording to the topography bakground. Hand tractors and tresher are much  utilized in the hilly areas, benguk carvers are much utilized in the low land plain areas, and cassava raspiers are much utilized in the mountain range areas. They aren’t difference signifiant the utilization of farm technology aording to accesibility. The low land plain areas and the hilly areas produce same activities, while the mountain range areas produce only four kind of same ativities. Diversification of works in the hilly areas absorbed a lot of manpower than those and the rest areas. Income generating from the utilization of farm technology in the hilly areas is more than that in the rest areas.

Abstract

District Muara Enim, South Sumatra Province has a potential region to develop an agriculture sector especially rice fields. The water resource such as Water Enim and Lamatang River support the capacity of the developing. Acording to the study in 1985 carried out by the BCEOM and Kampsax consultants, the lower Lematang region. Dangku Kiri, Dangku Kanan, and Modong with the total area of about 10.000 Ha has a highly potential to built rice field ith the technical irrigation. Based on the information, research of dependable flow of Lematang River to the irrigation requirement had been carried out by analyzing of all data collecting in those area  such as rainfall, climate, and discharge data. The result shows that the dependable flow of 20% probability of non exceedence is about 65.3 m3/sec. It is potential enough compare with the irrigation requirement of about 1.85 l/sec/ha or 18.5 m3/sec of total irrigation area. Technically, dependable flow of Lematang River is big enough but some constraints will appear especially in determining of free intake or weir because the river gradient is too low and the main  channel has been used by the people for navigation. To increase the accuracy of the research, an Automatic Water Level Recorder and one climatological station should be installed respectively in the alternative I location and in the irrigation area.
