The following discussion particularly stresses the techniques or research methodologies concerned with urban environment assessment. Given the fact that monitoring the quality of the urban environment is prime, some practical approaches to that problem are seriously needed. Due to the complex nature of the urban environment in terms of the elements, interrelationships of elements, and dynamic nature of their interactions, the author devises a model in the form of a combination approach to assess the urban environmental condition.The variety of urban environments reflects the social, economic, cultural, political, technological and demographic background of the nation and accordingly there should be a wise selection of the applied techniques and the environmental criteria used for assessing the urban environmental condition.The combination approach is an integration of terrestrial and aerial photographic approaches. Since each of the aforementioned approaches has its own weaknesses, the combination approach is expected to cover those weaknesses and can give more effective, accurate and reliable data on the urban environmental assessments.

This article is a result of an intensive study of literatures concerning urban growth management. It tries to examine the specific character of existing techniques for managing and controlling urban land growth and tries to match them to the Indonesian situation. The techniques can be categorized into two major types, i.e. urban and urral (urban-rural) orientation. Indonesian .urban sprawl can be distinguished into two models, i.e. the Java and Outer Islands model. Java model is characterized by leap-frog (see for example Jakarta, Bandung, Yogyakarta, Surakarta, Surabaya) and ribbon development (see for example Padang in Sumatra, Banjarmasin in Kalimantan, Kendari in Sulawesi). The physical, social, historical background are responsible for this conditions. The urban-rural oriented strategy is highly recommended for managing and controlling urban land growth on the island of Java whereas urban oriented techniques are suggested for managing and controlling urban land development on the outer islands.

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

In the discussion on any urban development, one can not neglect the so=called centrifugal and centripetal forces causing the flow of either people and functions from and to the inner parts of the city or the fringe. These two forces constitute the dynamic doers for the development of the city concerned. One of the aspects of urban development is a change in physical performance of the city itself and the sprawling process of urban features in the surrounding countrysides. The study is carried out in one of the portions of the fringe areas of the city of Yogyakarta that is receiving many arrivals either from the inner parts of the city or from the more remotely located areas. The discussion is merely focussed on one of these broad scopes, i.e., movement of people either coming from the inner parts of the city and coming from the more remotely located hinterlands. One of the subdistricts located next to the municipal boundaries is chosen as a case study and the respondents are selected randomly among new migrants in the last ten years. The result shows that nine reasons constitute attracting factors to the fringe areas. Centrifugal movement is predominated by those who are looking for more spacious placelspace for living and the lower price of laud whereas centripetal movement is predominated by those who are approaching their place of work.

The research was conducted in Yogyakarta Special Province. The main objective of this research is to find out the main factors influencing the change in agricultural land use especially rice field. The data used in this research is time series from 1980 to 2000. They were obtainedfrom several institutions such as: Central Bureau of Statistics (BPS), National Agency of Land Affairs (BPN) and Department ofAgriculture (Dinas Pertanian). Descriptive analysis and statistical test were performed against those data to find out the influence of geographic factors i.e. the population growth, the road development and the extension of built up area on the change in agricultural land use especially rice field. Distributed lag model is used to analyze the effect of road's length on agricultural land use change. The level and magnitude of relationship between areas of agricultural land use change and built up area, number of people and road length are calculated using linear regression.The research shows that the period of 1980 - 2000 in Yogyakarta Special Province has indicated very significantly the increase in population, the development of road and the extension of built up area. For the time being, agricultural land mainly in Sleman Regency, Bantul Regency and Yogyakarta Municipality has decreased. Sleman regency performed the largest decrease of rice field and followed after then by Bantul regency and Yogyakarta Municipality. The regency of Kulon Progo and Gunung Kidul have experienced reverse phenomenon i.e. the increase of rice field during this period. Individually or simultaneously, three variables used in this research (number of people, road's length and built up area) have significantly influenced the agricultural land use.

The research was conducted in Sleman Regency with 3 study area based on the extent ofagricultural land conversion. The purpose of this research is to examine the determinants ofagricultural conversion internally and externally, as well as the impact on the availability offood, especially rice. The research was conducted by survey method and statistical analysisregression Ordinary Least Square. The resultsof this research showed that the internalfactors which significantly affect land conversion is the price of land and land location in allareas of study. External factors have significantly positive are variable population, landconversion rules and land location, while the variable GDP in the agricultural sectornegatively. Availability of rice in Sleman Regenct zone 1 indicates the region from 1983 to2025 for the population minus the rice sufficiency. In zone 2 region between 1983 and 2005but it is still a surplus between 2006 and 2025 minus. In the area of zone 3 is projectedthrough 2025 the availability of rice is sufficient
