Abstract

The acceleration urbanization has resulted in the growing number of housing in the rural area of surrounding city. As a consequence the size of converted agriculture land is also getting larger. However, the distribution of housing development and the impact on agriculture land have not yet been explored thoroughly through research. Therefore, this research aims at exposing rural-urbanization around city, housing development, and the conversion degree of agriculture land for housing. This research was carried out in the rural area around Yogyakarta city. It encompassed administrative divisions of Sleman and Bantul Districts. The research method is based on secondary data analysis. Several data are among other on population growth and housing distribution of 269 locations within the two districts. Data analysis employs of frequency and cross tabulation, statistics of regression and t test. Result of the research shows that rural-urbanization in around Yogyakarta has been so high. The proportion of rural-urbanized area has increased from 8.7 percents in 1980 to 43.5 percents in 1990, and 66.5 percents in the year of 2000. Similarly, the proportion of rural-urbanized population has increased from 13.2 percents in 1980 to 54.7 percents in 1990, and within 10 years (2000) it becomes 75.3 percents. Housing development of the rural area at the surrounding city was started with only 7 housing locations consisted of 59 units of building in 1973 to be 269 housing locations with 35.356 units of building in 2000. The rate of increase of the building 1.349 units per anum. The spatial and temporal characteristics of housing development of rural and urban area are different. In northern part of Yogyakarta, housing development has been growing since 1973 with the rate of growth 601 units per anum. In southern side of Yogyakarta, housing development in the rural area of Yogyakarta has been growing since 1980 with the rate of growth of 967 units per anum. Analysis result shows that number of construction in all housing site will reach 72.775 units in the year of 2025, out of wich 22.878 units will be in Bantul and 49.897 units in Sleman. The impact of the housing development is the conversion of mostly agriculture land, i.e. paddy field (67%), and only a small percentage are dry land and homestead. Within the last 27 years there has been 1,232.93 hectares of land conversion i.e. 1,068.45 hectares in Sleman and 164.47 hectares in Bantul. The rate of conversion in Sleman is 41.09 hectares per anum, whereas in Bantul it is 9.67 hectares per anum. It is predicted that land conversion in around Yogyakarta City in 2025 will be doubled to be 2.464 hectares. The distribution of this conversion will be dominant in Sleman, i.e. 2.123 hectares as compared to 341 hectares in Bantul.

Abstract

Collecting data of soil erosion hazard terrestrially needs much time, high cost, and large energy. Therefore it is needed appropriate technology in addition to terrestrially decreasing necessity of time, cost and energy. Aerial photograph is picture of earth surface, which shape and place similar to condition on earth surface. Using aerial photograph in this research is expected to be able to take account for erosion factors. This research is conducted in Kecamatan Wuryantoro Kabupaten Wonogiri. Research method that used is aerial photograph interpretation with land unit approach. Amounts of soil lost are approached with USLE formula. Aerial photograph that used in this research is aerial photograph coloured infrared with 1:10.000 in scale and 1991 in year of taking photography. The result shows that using aerial photograph is very useful in supporting soil erosion rate calculation. Erosion rate at research area is 0.0968 ton/ha/year to 100.4344 ton/ha/year. This number is included in class of light erosion hazard (

Abstract

This research is conducted in Kartasura-Surakarta s area especially from an area that relatively does not grow (recharge area) to an area growing to became a city (discharge area). The area is phisiographically restricted by a groundwater contour (i.e. 200 m from sea level) and by three rivers (i.e. Pepe, Wiro, and Bengawan Solo). This research has one objective to know the distribution of groundwater quality in Kartasura-Surakarta that is located between Pepe river and Wiro river. This research uses survey model and description comparative model completed by cheking the field. On the one hand, survey model measures physical data and density population data, and on the other hand, description comparative model is used to know the influence of physical factors and density population factors on groundwater quality. Physical data and density population data collected by using purposive proportional random sampling are analyzed with trend analysis model, statistical analysis model (i.e. parsiil correlation and one-way variant analysis). The result of this research shows that the groundwater quality in the field declines. The trend analysis proves that most of the parameter concentrations of groundwater quality increase from the recharge area to the discharge area. Furthermore, the conclusion is also supported by the result of parsiil correlation analysis that shows a positive correlation between the distance and the most of the parameters, although the positive correlation between the depth of groundwater and the parameters of groundwater quality is weak. Moreover, the results of one-way variant analysis to the selected factors (i.e. geology formation, density groundwater contour, and density population) with the parameters of water quality show that there is a strong difference on the most of the parameters.

Abstract

Science that studied all of the aspect related to cave and their circles (speleology) in Indonesia does not still quite expand. Expantion more advanced need all sorts of research, publication and its interest to an academic party who get in touch with cave and their circles. One of them the basic of data collection about the existence and the spread of cave. The usual manner that is used to know the existence and the spread of cave, is by means of the analysis topography map which is continued by terrestrial research. Weakness for this manner is it need huge time, cost and energy. The making use of aerial photo can be done in supporting the basic of date collection, is the· interpretation to bug or detect appearances the phenomena in earth’s surface. One of them is appearances the edge of cave. The result of the research indicates that interpretation of aerial photo can be use to identify the spread of the edge of cave. It is olksified according to; the edge that obtained of center depression by the accuracy of 100%; the edge of cave that obtained of slope depression (the accuracy of 33.3%); the edge of cave that is obtained of river current (the accuracy of 100%); and the edge of cave that obtained of fragment (the accuracy of 50%).

Abstract

Slum, a dwelling that is statutorily unfit for human habitation, is still the big problem in, especially, cities of developing countries. This article highlights the development of slums in Yogyakarta City along 1970-2000, and it’s merely focused on spatial and socio-ecological development. The aims of the study is to analyze the distribution and development process of slum dwellings. Distribution of slum area is taken from interpretation of time-series aerial photos. The change of extent and distribution of slum is analyzed using Geographic Information System. To obtain the socio-economic characteristics of slum dwellers, the survey method is chosen. The respondent are selected randomly among head of household that represent each settlement units. Quality of settlement are determined by total score of 15 selected variables. The result shows that the first category of slum was increased 74.4 hectares from year 1970 to 2000, the second category was increased 47.6 hectares, and the third was 131.1 hectares. Nevertheless, the process of slum development in Yogyakarta City includes in "continuous" type, which slowly and long period of creation. Densification and aging process is two of the main causes of slum expansion. Distribution of slum unit were driven by rivers that next to city center. According to this research, it’s found out that the slum dwellers are characterized by the new migrant who had low income and education, working in the informal sector, and renting the house.

Abstract

This study is carried out in Nusukan, Banjarsari, Surakarta. The problems that are related to economic crisis in Indonesia are the supply of contraception, the weakening of people purchasing power so they influence the realization of family planning program. The goals of the study are: to know the supply of contraception for poor household, to study the influence of the effect of economic crisis for the participant of family planning, to study the change of birth control and its effective strategy and to know the quality of family planning service. The data are collected using observation, and questionnaire. The study takes the area in which it has more productive couple, the percentage of poor families and the prosperous families I that belong to productive couple whose age 20 to 49 years old, at least they have two children, and participant of family planning or ever followed it. The result of the study shows that 82% respondents can get contraception easily before and at economic crisis. It is one of the important factors, for which the participant of family planning is still high. Although the economic crisis influences the price of contraception and family Income, it does not affect the participant of family planning. 87% respondents participate actively the family planning. This shows that the people have realized the importance of family planning program. There is an impact of economic crisis for the change of the ways of birth control. 38% respondents have changed over their strategy from modern to traditional contraception and the contrary, and from modern contraception to the other one. Some of them are abstention. The level of the people adaptation is high enough. They use various ways to prevent of being pregnant. 92% respondents do not want to be pregnant. If it happens an unwanted pregnancy, 15% of the respondents will abort their pregnancy. This is the challenge for the officers and the government to supply safe and accurate contraception and to give clear explanation about the effect of abortion from healthy and religious aspect. The service of family planning by the government and private institution is good enough (81%). Respondents can get contraception (especially tablet) easily; cheap and free of charge, but the other ones such as spiral is more difficult because it is more expensive and limited.
