Abstract

Settlement means a place (spatial) or an area where population conentrated on and live in together to make use of the environment to survive direct and develop their living. Pattern and distribution of the settlement constitute a closed connection. The settlement distribution deliberates the fact of where the settlement exists or is not obtainable in an area; while the settlement pattern constitutes a distribution characteristic which has much more connection with the effect of the economical historical and cultural factors. There are some measurement methods of the distribution pattern i.e with the neighborhood analysis formula (t) where if t = 0 it means the settlement pattern conentrates, t = 1 shows the random settlement pattern (uneven distribution), while if t = 2,15 shows the uniform (homogeneous) settelement pattern. The second method is the Demangoens Index (C) which only considers the total of the population, besides C score of the concentration, random, and uniform of the settlement pattern are not detected. Another measurement method is score per “grid square”. The method of R scale is also applicable in the measurement, in which R score is concerned with 0 – 2,1491; if score of R = 0,7 it shows that the settlement pattern would be in group; R = 0,7 – 1,4 means an uneven distribution and R = 1,4 – 2,1491 shows the evenly distribution of the settlement pattern.

Abstract

River discharge quantity is highly depended on rainfall and initial condition of river discharge; hence, the river discharge has auto-correlation relationships. This study used Vector Auto Regression (VAR) model for analysing the relationship between rainfall and river discharge variables. VAR model was selected by considering the nature of the relationship between rainfall and river discharge as well as the types of rainfall and discharge data, which are in form of time series data. This research was conducted by using daily rainfall and river discharge data obtained from three weirs, namely Sojomerto and Juwero, in Kendal Regency and Glapan in Demak Regency, Central Java Province. Result of the causality tests shows significant relationship of both variables, those on the influence of rainfall to river discharge as well as the influence of river discharge to rainfall variables. The significance relationships of river discharge to rainfall indicate that the rainfall in this area has moved downstream. In addition, the form of VAR model could explain the variety of the relationships ranging between 6.4% - 70.1%. These analyses could be improved by using rainfall and river discharge time series data measured in shorter time interval but in longer period.

Abstract

There had been some changes of poverty preventation strategy for the government of the New Order. In the development process, the change of the strategy from economy growth method to the implementation of “Presidential Decree of Underdeveloped Territorial Program (IDT) “actually emphasized on the increased attention to the poor. It was proved that the combination of various programs could decrease the poverty rate both quantitatively and significantly. However, because the pattern of the top-down and the feature of the charity remained to dominate on the overall strategy, the poor could not have develop significantly independent. Thus, poverty preventation strategy in the future must emphasize on the development of the poor’s creativity, initiative, and capability based on the mobilization of the local resources, so it can make the poor develop and grow independently. In such a way, ontinual development will reasonably run. A change of strategy needs the reshuffle of political structure to democracy.

Abstract

The following issue explains the role of geography study in spatial lay-out and regional development, taking the regional development of Sukoharjo regency as the case study. The role of geography study in spatial lay-out and regional development lies mainly in the effort to achieve geo information system, i.e. information of regional landscape with its all characteristics, regional problem, regional development potential and the definitive factor of regional development. Making use of geography analysis, Sukoharjo as a brief out line has three geomorphology units with its different physic potential and soial economy, and up  to the present it has a tendency of different land  function. The three units of geomorphology mention above are: alluvial plain, fluvio-volcanic foot plain of Lawu, and shouthern hill slope of Baturagung. And then, to  support the area development of JOGLOSEMAR the future development strategies of Sukoharjo regency is distinguished into three zones, i.e.: industry and comercial zone, urban residential and institution zone, open sphere land and recreation zone.

Abstract

This paper aims to explain the inter relationship between urbanization and slum and squatter settlement phenomena in urban areas, focusing on two cases in Jakarta and Yogyakarta. Marginality theory and dependence theory are to explain the two phenomena above, because these theories have different assumption and different explanations about slum areas. Thus, the solutions offered are different too. The result of Tadjuddin and Taylor research into the slum and squatter settlement in Yogyakarta and Jakarta suggest that the phenomena of the slum settlement in this cities could not be explained by a single theory, either marginality theory or dependence theory.

Abstract

The study examined the extent of community appreciation or response to government policies at the potential lanslide areas and the influencing reasons. By interviewing 35 representative informants, men and women, and divided into old, young and adult, then the data are analyzed and interpreted using the theory of action and the theory of symbolic. The results showed, the community, dominated by the farmer, were able to respond and deeply understood the government policies, particularly policies of spatial planning. This was indicated by the increasing knowledge of the community against areas that were prone to landslide and other sign that the region was going to experience a landslide. Almost all respondents said that they live in hilly areas prone to landslides, and they knew how to cope with and respond to these signs. However, government policy declaring that the community were expected to move from the area considered as dangerous was still lack of community’s attention. This was due to the undersired experiences of the community in the new area which did not make their lives better, both in terms of livelihood as well as in terms of their social-culture life.

Abstract

After the rise and the fall of the tides and the change of the activities as the phenomena which happen in the daily life of sociaety, the hange of spacing or distributionn of industrial businesses becomes one of the new phenomena. The objective of this research is to know the process of the diffusion from leather industry in Magetan Subdistrict. This research uses secondary data analysis and direct observation. The result of this research shows that the change (the rise and fall of the tides) in leather industry has producted the movement of distribution or spacing in which the center of the main production is declined and the new center may arise. In this movement, it seems that the existence of the specification on types of activity, like having similar leather, shoescraft, beltcraft, and sendalcraft become the serious phenomena. This kind of the change and its development is signed by the change of position from becoming employee to be new employer, having some employees that may become the employers at any time and so forth. The style of the diffusion which happen is the style of mixing diffusion in which the business on leather industry becomes wider reaching around the village while the original village (Kauman) is still as the center of industry, although it has so limited activities because the business is always declined.

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.
