Abstract

Stock status of Yellowfin tuna in Indian Ocean on southern water of East Java currently is predicted undergoing overfishing or close to overfishing which is very alarming from sustainability context. A research has been done on Yellowfin tuna fisheries sustainability based on ecology, economy, technology, social and institutional dimensions. Collected data are analyzed using RAPFISH (multidimensional scaling/MDS, leverage analysis, monte carlo analysis), and comparison pairwess analysis to asses multidimensional sustainability of Yellowfin fisheries.Research result shows that Rapfish index for ecological sustainability is 57.83%, whereas economical, technological, social and institutional sustainability are consecutively: 68.14%, 98.03%, 44.89% and 47.88%.  Multidimensional sustainability status assessment result show sustainability index 64.54 %, or Fairly Sustainable. Of those dimensions, social and institutional dimension have the lowest proportion in Yellowfin fisheries in Indian Ocean economic exclusive  zone (EEZ) they are 7.63% and 4.24 %. Keywords: yellowfin tuna, sustainability, EEZ, Rapfish

Abstract

This study aims : (1) to analyze the status of coastal ecosystems, (2) to analyze factors that affect the quality of coastal ecosystems, and (3) to prepare the direction on spatial planning in coastal areas of Ambon Bay Area. The analytical method used in this study is the analysis of ecosystem status, principal components analysis, analysis of Geographic Information Systems (GIS) and analysis of dynamic systems. The results showed that the condition of ecosystem status damaged in 2008, whereby, the status of mangrove ecosystems is moderate with a density of 1100 trees/ha, the status of seagrass ecosystems damaged by percentage cover of 38,76%, and the status of coral reef ecosystems are damaged by the percentage of live coral is 42,27%. Ecosystem conditions in Ambon Bay Area is affected by land use on land, namely forest area and population. Refferral of land use planning in Ambon Bay Areas wich recommended in this study for a period of 20 years of protected areas and cultivated areas. Protected areas is aimed at 9.480,70 ha or 41,21% of land area, while the allocation of space for the cultivation area is 10.416,30 ha (58,79% of land area). To reduce the pollutant into the waters, planned buffer zones (coastal and riverine border for 11,69% of land area), which serves to absorb pollutants and protect the inland waters of the tidal influence, while still controlling the waste coming into water By using dynamic systems analysis, created the scenario of land use planning in Ambon Bay Area that integrates land and wet land. The scenario used in this study is the optimistic, pessimistic and moderate scenarios. The variable that is used to determine of policy scenarios spatial planning based on the rate of population growth is 2,5% per annum, while variable forest area of at least 30% of the area. Of the three scenarios, the scenario chosen for the land use planning policy in Ambon Bay Areas in the future is to use the moderate scenario. The simulation results moderate scenario, the status of coastal ecosystems is improved from the criteria of the coastal ecosystem damaged by coastal ecosystems index 44,44% in 2008 turned into good condition with the index of coastal ecosystems 88,89% in 2029

Abstract

This research described the application of emergy analysis to evaluate the sustainabil-ity of small scale fisheries activities. An advantage of emergy analysis is the ability to quantify environmental and economic inputs and outputs on a common basis. In this study, we con-structed emergy accounts for the small scale Fisheries activities in Cilacap District. The result of EYR value indicates that small-scale fishing activities do not contribute to the balanced de-velopment of regional economy. The value of the ELR is very high, showing the large number of small-scale fishermen to the intensity of the use of fishing gear. The comparison between the results of the emergy environmental burden (ESI) fishing activities by small-scale fisher-men in Cilacap regency potentially unsustainable.
