Abstract

Sea cucumbers are marine invertebrates that have a high selling value and are even traded on the international market. Tagalaya and Tolonuo villages are villages in North Halmahera that have sea cucumber fishermen, and sell their processed sea cucumbers in dry form. This study aims to identify bioactive compounds, toxicity and antioxidant activity of sea cucumber extract Stichopus horrens obtained from Tagalaya Village and Tolonuo Village, North Halmahera. The results of the analysis showed that the highest yield of the extraction process was sea cucumber B which was 16.93%, the LC50 value ranged from 332.16 to 368.54 ppm which was included in the toxic category. The biochemical compounds found in both sea cucumber extracts are saponins. Sea cucumber extract showed no antioxidant activity

Abstract

The waters of North Halmahera are a fishing area with abundant potential of small pelagic fish. Fishermen in Tobelo use a mini purse seine fishing gear which in local terms is called pajeko. The catch of pajeko fishermen is dominated by Mackarel tuna and Mackerel scad. The aim of this study was to determine the quality of fish caught by fishermen who are sold in one of the markets in Tobelo through organoleptic and pH analysis. Samples were taken randomly and analyzed descriptively so that the data were presented in the form of figures and tables. The results of the average pH analysis ranged from 6.00 - 6.50 and the results of the organoleptic analysis showed that the value was above 7 which indicated that the fish was still fresh.
