Abstract

The development of GPS (Global Positioning System) technology which is measuring position by satellite, has taken a great metodology aspect of position on surface of earth. The standard GPS measurement takes an absolute positioning. To develop the accurate abd precision, it is used the differential method. Differential GPS measurement can be much more accurate than standard GPs measurement, wherever the method uses one receiver as base station/ reference and the other receiver as field station in a same time. That could reduce and eliminate drifts and errors. The aim of research is use the differential method of GPS survey to map the ocean boundary of Central Java Province. Physical data which neede are base line and base point. Base line were taken from obsrvation of longtime Landsat TM image band 5th based o opinion that shore line are clear seems and easy to interpreted at 10.00 am according to Landsat satellite reording time and the lowest tide time as base line. Location of lowest tide were selected at conspicuous place, such as cape, dry shore, etc and measured base on the BPN (Badan Pertahanan Nasional) base/ reference point (orde 2 and 3) on the district, with GPS differential metod. Twelve miles distance from base line of ocean bounddary is belong to province and 1/3 of is belong to district. Characteristic of marine landform as cape, bay, estuaria, attended to international rules. Final report of the research were 1) oean boundary map of Center Java Province, 2) the location and base/ reference points (orde 2 and 3) that could be reference as a base point differential method.

Abstract

Technical development of Global Positioning System (GPS) is the positional determination system of ground control point in the earth surface, which based on satellite. It leads to the significant influence on the methodological aspect of positional determination survey in the earth surface. Global Positioning System gives the three dimension position (X, K Z) or longitudinal, latitude and altitude which are formulated in the reference of World Geodetic System (WGS) in 1984. The data characteristic is the first data, which is required in the survey of limit mapping of historical and archeological site. This article tries to explain the possibility of using the technology of Global Positioning System (GPS) to map the archeological site which contains of potential, ohstacle, methodology and case study in Boko Prambanan temple area. It is also utilized to the possibility of using the Geographical Information System (GIS) to analyze the spatial existence site of environmental condition.

Abstract

The aim of this research is to analyze of DIY coastal landscape with visual preference analysis for suistanble coastal tourism development and management. The unit of analysis that used is coastal typology. The guideline in deciding the classification of coastal typology is using the Response-Process System with relief/slope, main constructing material, genesis process and dominate process happened in the meantime such as tide, wave and river flow. This response-process system divide the coastal typology into seven classes including coastal typology of land erosion coast, sub aerial deposition coast, volcanic coast, structurally shaped coast, wave erosion coast, marine deposition coast and coast built by organism. The method of SBE (Scenic Beauty Estimation) is used for visual preference analysis, and the method used to compose the policy of costal tourism development is SWOT method. Result shows that all seven coastal typology are found in the coastal area. Land erosion coast and coast built by organism dominate in Gunungkidul coastal area and then in Bantul and Kulon Progo coastal area are dominated by marine deposition coast and sub aerial deposition coast. Volcanic coast, structurally shaped coast, wave erosion coast can only be found in a small area of Gunungkidul coast. Each of this coastal typology has a special land characteristic which can be used to develop its potential. Coast built by organism is very suitable for tourism activity proved by the high score of SBE from the respondents. Recommendation for developing coastal area in area of interest is by developing the coastal natural resources suitable to its physical typology, because this will make the management of coastal area for continuous development easier. Recommendations for coastal management in Gunungkidul including mapping and classification of protected karst area and mineable karst area to secure the run of coastal area management, for coastal management in Bantul using Managed realignment which plans for retreat and adopts engineering solutions that recognise natural processes of adjustment, and identifying a new line of defence where to construct new defences and move seaword model by constructing new defenses seaward the original ones. Last, for Kulon Progo coastal area using hold the line model whereby seawalls are constructed around the coastlines.
