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.

Abstract

The study sites were located in the river mouths of Kahayan and Katingan Rivers of Central Kalimantan. The purpose of this study was to evaluate concentration of heavy metals on the water, sediment, Arius (catfish) fin through concentration and bioconcentration factor (BCF); data were analysed by regression and correlation analysis. Collected samples were water and fish.Water sample and fish bone were analysed by Atomic Absorption Spectrophotometer (AAS). The results indicated that the concentrations of Pb>Cd>Hg were occurred in the water and hard fins, which the bioconcentrations of Hg>Cd>Pb were in the hard fins, while the bioconcentration factors (BCFs) of Pb>Hg>Cd were in the sediment.Moreover, it seems that heavy metals in the waters absorpted and accumulated by sediment and hard fins increased along with heavy metal concentration in the water, whereas heavy metals in the sediment absorpted and accumulated by hard fins increased along with heavy metal concentration .in the sediment.

Abstract

The largest fraction of freshwater fish diversity is presented in floodplain ecosystem. Moreover, floodplain fisheries in Kalimantan have an important contribution to local community livelihoods. Floodplain ecosystems are faster to be damage and loss than other ecosystems. Consequently, conservation of fish habitat is urgently needed to maintain fish diversity. The objectives of this study were to give strategies of fish habitat conservation for maintaining fish diversity, based on biophysical and social analysis. Studies were carried out in Petuk Ketimpun District of Palangkaraya Municipality. Biophysical variables were studied by monthly samples taken from May 2005 to April 2006. These were carried out at three stations with different habitat type, includes forested swamp, opened swamp, and river. Social and cultural information collected by interviewing with fishers and local government agencies. A total of 4278 fishes were collected consisting of 50 species and 19 families. Forest swamps and river are habitat priorities to be conserved. The conservation of forest swamps is directed to maintain of the habitat structure, while the conservation of river is directed to maintain water quality and to maintain river as fish refuge site at low water season. Fishery regulation is priority used for maintaining fish diversity in opened swamps.
