Abstract

This study aims to analyze the condition of the coral reef ecosystem in the waters of Kiya Village using the Line Intercept Transect (LIT) method along a 25-meter transect at a depth of 5 meters. The observation results show that the percentage of live coral cover is 29%, which is classified as moderate according to the criteria of Gomez & Yap (1988). The composition of other substrates consists of Dead Scleractinia 12.8%, algae 12.6%, other fauna 22.4%, and abiotic components 23.2%. The relatively high Dead Scleractinia value indicates ecosystem degradation, which is suspected to be influenced by natural and anthropogenic factors, including the potential impact of nickel mining activities in the Gemaf area. The significant proportion of algae and abiotic components has the potential to inhibit coral regeneration and trigger shifts in the benthic community. However, the moderate category for live coral cover indicates the potential for recovery if ecosystem-based management, control of pollution sources, and community involvement are implemented. The results of this study are expected to serve as a basis for conservation and sustainable management efforts for coral reefs in Kiya Village.

Abstract

Dried anchovies (Stolephorus sp.) are widely consumed in Indonesia due to their affordability, nutritional value, and availability in traditional markets. However, as a dried fish product, they are highly susceptible to microbial contamination if not properly handled, which may compromise food safety and consumer health. Pathogenic bacteria such as Coliform, Escherichia coli, and Salmonella are among the most concerning contaminants, as their presence in food products can cause gastrointestinal illnesses ranging from nausea, vomiting, and fever to severe outcomes. This study aimed to determine the presence of pathogenic bacteria in dried anchovy samples obtained from three traditional markets in Ternate City, North Maluku Province Bastiong, Kie Raha, and Dufa-Dufa. Microbiological analyses were conducted using Total Plate Count (TPC), Coliform, Escherichia coli, and Salmonella tests, with reference to the Indonesian National Standard (SNI). The results indicated that microbial counts were far below the rejection threshold, and the pathogenic bacteria tested were all negative. These findings suggest that dried anchovies sold in the three markets remain safe and suitable for consumption, although continuous monitoring and proper handling practices are recommended to maintain product quality and food safety.
