Abstract

Tuna (Thunnus sp.) is the second largest foreign exchange earner after shrimp. One type of tuna which is an export commodity is yellowfin tuna (Thunnus albacares). Research on the effect of the distribution of sea surface temperature in the Indian Ocean south of Java on the catch of yellowfin tuna (Thunnus albacares) has been carried out at the Nizam Zachman Ocean Fishery Port (PPS) from April 8 to April 30, 2021. This study aims to determine the effect of sea surface temperature (SST) on the catch of yellowfin tuna. The research method used was the method of observation and analysis of satellite imagery. Coordinate data and the number of catches were obtained from the Ocean Fishery Port Logbook (PPS) Nizam Zachman. SPL data obtained from satellite imagery Modis Aqua Level 3. The data was obtained and then analyzed using a simple regression test and the F test results of regression analysis showed that the correlation coefficient (R) of 12.7% and the coefficient of determination (R2) of 1,6% means that 1.6% of yellowfin tuna catches are influenced by SST and 98.4% is influenced by other factors. The F test results show that the SPL significance value is 0.332. The conclusion is that changes in SST have no significant effect on the catch of yellowfin tuna.

Abstract

Transmission of Escherichia coli in food can occur through contact with infected workers, as well as tools and materials used during food processing. One way to determine the presence of E.coli in processed fish balls is to perform a bacteriological test. The purpose of this study was to detect the presence or absence of bacteria in fish balls so that it can be seen whether these meatballs are in the hygienic category and are suitable for consumption or not. This type of research is a laboratory experiment. This research was conducted at the Maluku Provincial Health Laboratory on 26-28 January 2022. The sample used in this study was fish balls taken by purposive sampling (taken according to research needs) for laboratory testing. Based on the results above, it shows that the E.coli bacteria found in the meatball samples during the phenotyping test with Vitek 2 compact both at a dilution of 10-1 to 10-3 were not identified because they had not passed the maximum limit. Based on the results obtained, it was found that the fish balls made by service participants in Mamala country were still in accordance with the criteria of the Indonesian National Standard (SNI) No.7388:2009 regarding the maximum limit of E.coli bacterial contamination in processed meat products made by the government for the protection of consumers regarding the quality of the product in circulation and declared to meet the requirements for the maximum threshold of microbial contamination in food if the value is 3/g for the status fit for consumption. The condition of the value of the test results of the fish balls sample under study is due to the fact that food makers or processors when processing fish balls still use the correct sanitation and hygiene principles and according to procedures.

Among the small islands in Indonesia with mangroves at its shorelines is Tunda Island, located in Serang District, Banten Province. However, various threats, such as shipping industrial waste and climate change, have caused the mangroves of Tunda Island to decline. This study aims to describe the condition of mangroves on Tunda Island, assess the local community's perception level of mangrove management, and formulate a strategy for managing the mangrove ecosystem on this island. This research was conducted on Tunda Island, Banten Province in January 2022. Mangrove ecological data were collected at four stations using purposive sampling, and questionnaires were distributed to collect community social data from 95 respondents. Mangrove health was analyzed using the Mangrove Health Index (MHI), while community social data were analyzed using the Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis and the Quantitative Strategic Planning Matrix (QSPM). Results showed that the mangroves fall into the category of poor, with an MHI of 14.75% on the north side; poor with 17.16% on the west side; moderate with 51.07% on the south side; and moderate with 65.89% on the east side of the island. The level of community perception of Tunda Island mangrove management is 60.66%, which implies a positive perception, and that the people of Tunda Island have an adequate understanding of the role of the mangrove ecosystem. The priority management strategy is to empower the community in the accelerated program to rehabilitate sustainable mangrove ecosystems by providing equal opportunities and rights for the community.
