Abstract

A study of spatial disttribution of urban failities and its impact on settlement pattern had been conducted. Southern part of Surakarta Municipality is chosen as study area. The aim was to study the correlation between spatial distribution of urban public facilities and settlement pattern. To obtain the settlement pattern and urban facilities distribution, manual photo interpretation and field survey method were used. The data were analyzed using geographi information system and statistical analysis tools. Map overlay module in the P Ar/ Info was used in order to join each variables of this research. To know the correlation between spatial distribution of urban facilities and settlement pattern, the multiple regression technique was used. The result shows that there was a positive signifiant relationship between urban public facilities distribution and settlement pattern. It means that the more distributed of urban publi facilities the better of settlement pattern (dense – uniform – large size building). Finally, condition of settlement pattern depends on how the goverment was able to manage the distribution of urban failities.

Abstract

The Government of Japan and the Government of Indonesia has signed a loan agreement Sector Program Loan (SPL) INP 23 for Settlement Sector (Human Settlement) through the Japan Bank for International Cooperation (JBIC) which is intended to overcome the economic crisis and its impact in Indonesia since 1997. Research this carry out an evaluation of the benefits of settlement activities that have been implemented in order to know how much contribution the benefits of the settlement Sector program implemented through the SPL IVI-23, both the recipient community, relevant agencies that manage the project, and local governments that implement and oversee the development of the project . The survey was conducted by using a regional approach, ex post facto, and institutional. The selection of cities and counties samples were selected based on three things: the completeness of the program, the amount of funds, and the number of packets. Next, the results of the rank- ings were selected based on 1) the highest ranking, middle, and low; 2) distribution based on the distribution of the three parts of Indonesia, the western, central, and east; and 3) exclude conflict areas. The results showed that in general the development and results of settlement construction is quite beneficial for the government and society. Among other things more organized neighborhoods, neighborhoods healthier, improved infrastructure, and increased mobility of society. Special benefit shows the influence of the change in service, use of services, and its impact. Development of clean water service level (L) is satisfactory, the level of use (U) range in the level of useful and very useful, and beneficial impact. Drainage construction provide the level of service (L) is very satisfactory, the level of use (U) ranged between levels is useful and very useful, and beneficial impact. For the construction of basic infrastructure settlement (IS and hi, i) provide the level of service (L) is very satisfactory, the level of use (U) range from useful to extremely useful, and gives effect (B) is useful.

Abstract

The objective of this research were: 1) to study the degree of soil development, and 2) to study the spatial correlation between the degree of soil development and the degree of mass movement susceptibility in the research area. The sampling method applied in this research was stratified sampling. Soil mapping units were applied as strata. The sample within strata was determined according the degree of mass movement susceptibility. The degree of soil development was determined using quantitative method of color indices and proflie index. The color indices were Buntley – Westin (B – W), Harden (H), and Hurst. The profile index was determined using solum, texture, structure, and soil consistency. The degree of mass movement susceptibility map was taken from PSBA UGM (2001). Spatial correlation between the soil development map and the mass movement susceptibility map was analyzed using “error matrix”. The result of this research indicated that the degree of soil development in the research area could be classified into three classes, i.e. class 1 (weakly develop soil); class 2 (moderately developed soil), class 3 (strongly developed soil). The degree of mass movement susceptibility was classified into three classes, i.e. class 1 (low susceptibility), class 2 (moderate susceptibility), and class 3 (high susceptibility). The result of error matrix calculation between mass movement susceptibility and soil development were 9.56%; 21.96%; 30.21% for BW + Ha, Hurst, and profile indices respectively. There values showed that there were low spatial correlations between the degree of soil development and mass movement susceptibility in the study area.

Abstract

Land use in upper catchment of Cikapundung progressively do not in control, so that many land use disagree with required condition. The objectives of the research were to: 1) evaluating of existing land use suitability with to its land suitability; and 2) compiling simulation land use model which have been formulated to study the expense of conservation, beneficial crop type and conservation action alternative. In this research made three submodel (erosion submodel use USLE and Arsyad, runoff submodel use Bransby and Williams, and social economic submodel use B/C ratio and NPV); and than integrated to become one land use model in upper catchment by using computer program package “Poersim Version 2.5c”. The model is simulation by considering aspect land suitability, is then obtained by form land use sustainable. Land use in Cikapundung upper catchment equal to 70,52% disagree with land condition. The rate of occured erosion in dry land, pine forest and plantation of quinine have is abysmal of permissible erosion, while in natural forest, rice field, and grass land still is normal. Run off coefficient from all region per year go up equal to 0,3878%. And B/C dry land equal to 3,33. To maintain thickness of land and reducing runoff coefficient but admiting of to support life  farmer, minimum 10% from rest of obtained production in using to defray activity of conservation. Crop vegetable type which still profit is potato, chickpea, and pepper so long as minimizing 5% from rest of obtained production to be used for the activity of conservation, appropriate action conservation type is credit terrace because can be done step by step every process farm so that farm can be exploited on an sustainable.
