Abstract

The The waters of Raja Ampat have a healthy coral reef ecosystem and a wide variety of species so it has a high abundance of coral reef fish. One of the indicators of fertility level in water is chlorophyll-a and its high and low are influenced by sea surface temperature. The purpose of this study was to determine the relationship between chlorophyll-a content and sea surface temperature using satellite imagery data on the community structure of reef fish in the waters of SAP Raja Ampat. The coral reef fish data collection method used UVC (Underwater Visual Census) while the chlorophyll-a content and sea surface temperature used spatial analysis. The results showed that the reef fish diversity index value was 4,1 - 4,6 in the high category, uniformity 0,88-0,96 in the high category, dominance 0,014 - 0,026 in the low category, for abundance 244.340 ind/ha – 403.520 ind/ha and biomass 131,45 kg/ha - 204 kg/ha. The chlorophyll-a content obtained was 0,366 mg/m3 – 0,511 mg/m3 and the sea surface temperature obtained was 30,717°C – 31,899°C. The results of the relationship of reef fish community structure with chlorophyll-a content and sea surface temperature do not have a significant correlation.

Abstract

The Covid-19 pandemic has had a major economic impact on the community, including those on small islands. Related to this, the government as a decision maker in various programs to improve community welfare needs to think about effective and efficient forms of programs to intervene in small island communities. One of the government's basis for making these decisions is through the existing conditions of community economic resilience. Without this information and analysis regarding the existing conditions, the government will find it difficult to implement targeted intervention programs. This study aims to determine the level of economic resilience of the people of the small islands of Gili Matra as destinations that are most affected by the Covid-19 pandemic, as well as to formulate interventions that will be carried out to increase the resilience and adaptive capacity of the people of small islands in the face of the Covid-19 pandemic. The results of this study indicate that the era of the Covid-19 pandemic has had a significant impact on the economic resilience of small island communities, including the Gili Matra TWP area. During the Covid-19 pandemic, there was a weakening of business, loss of assets, loss of livelihood, loss of markets, inability to produce resulting in loss of income, so an adaptation strategy was needed to face threats and opportunities to the economic sustainability of the Gili Matra TWP community. Economic assistance for communities affected by Covid-19 is one solution in increasing the adaptability of the Gili Matra TWP community. There are five forms of intervention that need to be carried out in economic assistance, namely: 1) Strengthening/Formation of Joint Business Groups, 2) Strengthening group capacity, 3) Assistance with production equipment and production raw materials, 4) Repackaging rebranding and business nameplates, and 5) Online Marketing Training.
