Abstract

This article is to present the changing urban plans of the city of Yogyakarta and their impacts on its physical appearance. An intensive study of extensive materials is carried out in the library and governmental institutions particularly, the regional planning board of the city of Yogyakarta. By comparing the earlier simplest plan, to the recent one, a pronounced development of the respective plan can be detected. There were five types of Yogyakarta's plan i.e. Mangkubumi's Plan, Thomas Karsten's Plan, Putuhena's Plan, Purbodiningrat's Plan and the present plan which will be reviewed here. Some conclusions are particularly directed toward the present plan because this one is not more than a synthesis of the previous plans and the inputs are expected in order to be used for further elaboration

Abstract

This study deals with the application of remote sensing in monitoring mangrove disappearance. Color aerial photograph scaled to 1:30.000 of 1981, numerical data of Landsat satellite taken in 1985 and SPOT satellite data of August 30, 1988 were used. The photograph was interpreted manually, while the digital analysis with DIDACTIM software was applied to the Landsat and SPOT data. Barycentric supervised classification procedure was used in clasiffing mangrove and land use classes. Key interpretation of mangrove type was obtained by field check in 1989.Two types of mangrove (Avicennia sp and mixed mangrove) could be identified both on the aerial photograph and on the SPOT data. The extent of mangrove in 1981 was measured manually, while those in 1985 and 1988 were obtained by multiplying the number of pixel (picture element) and the spatial resolution of Landsat and SPOT respectively. During seven years (1981-1988), there were 852 hectares of mangrove in the study area which have been cut.For mangrove reforestation purposes, two mangrove zonations are presented ; one is based on the salinity gradient, while the other is based on the Ciloto formula. It seems that the second zonation is quite good for the study area.

Abstract

The present environmental situation is not compatible with our expectations. Pollution, erosion, floods and droughts have hit many parts of the world, and these disasters give us reflections on how serious are the environmental problems that befalls this planet of ours. In meeting its needs, mankind has exploited the environment to the utmost without caring about environmental conservation. Moreover, with the population explosion after the 1950s and the dependency of life upon the natural processes, the cultivated land to be inherited by future generations has gradually become increasingly barren and fertile.Efforts are absolutely necessary to check increasing population growth rates, to raise the standard of living for all people and to arouse and awareness of sustainable development policies so that a compability between development activities and environment can be achieved.

Abstract

In this article, the assessment of centrality of settlements in a district in Central Java is discussed This with a view to determine a system of service centres in the area which is functional for regional planning purposes. The study area, Bantu! District, is a densely populated area which boasts a large variety of services. The assumption is tested that both the geographical location of the district, close to the city of Yogyakarta, and the high mobility of the population, due to a well-developed public transportation system, allow for a situation whereby the hierarchical position of a settlement, based on the combination of services provided is not necessarily similar to the centrality of that very settlement, based on the number of incoming interactions. From an analysis of an intensive set of primary data, it shows that although the level in the hierarchy of a settlement largely coincides with its centrality level, the centrality level of some settlements considerably deviates from what might be expected on basis of these centres' service level.

Abstract

Many developing countries, Malaysia included, have relied quite heavily on the policy of industrial decentralization to uplift the lagging economies of their peripheral regions. In Malaysia, the Malaysian Industrial Development Authorithy (MIDA) - a federal agency - plays a major role in persuading foreign enterprises to locate in the periphery. In addition to MIDA there are plethora of state agencies which implement state industrial policy. Development officials, in their effort to attract more industries to their respective regions, work on the premise that certain locational factors are critical to investors locational decision- making process. Obviously, development officials have their own perceptions of the attractions and disadvantages of the periphery. This paper (a) examines whether the officials have a good grasp of the industrialists dominant motives for selecting Kedah as production location, and (b) discusses the implications for industrial development if officials assumptions do not concur with industrialists real reasons for selecting Kedah location.

Abstract

For a large watersheds sediment yield can be more accurately estimated if the large watersheds is divided into sub-watersheds to compensate for non-uniformly distributed sediment sources. The effect of drainage basin hydraulics can be included by routing the sediment yield from sub-watersheds to the large watersheds outlet Sediment routing increase prediction accuracy and determines individual watersheds contribution to the total sediment yield.
