Abstract

Sipuncula, a marine biota which is commonly called a peanut worm, is a marine biota that is a little "controversial". Some literature also refers to these animals as "unsegmented marine worms" or unsegmented marine worms. Siasia (Sipunculus nodus) usually lives in coastal areas, especially around seagrass beds, mangrove forests, and coral reefs. These biotas tend to inhabit the bottom of the waters, especially in the substrate, so they are categorized as infauna benthic organisms. Siasia (S. nodus) can inhabit soft and hard substrate areas. Based on its ecological function, seagrass forms associations with various kinds of marine life as food providers, shelters, and places to live, causing high diversity of marine life. The basic substrate in the form of flat stones and gravel is a good living environment for macrozoobenthos because it is rich in organic compounds so it has a big population density and diversity.The bottom of the waters in the form of sand and fine sediment is not a good living environment for benthic animals. Factors affecting density and diversity are environmental conditions, habitat, and diet. The same factors also affect the nutritional content of Siasia (S. nodus). So, it is feared that when the population density of Siasia (S. nodus) becomes high in the water there will be competition for food which will have a direct impact on the nutritional content of Siasia (S. nodus). The population density of each water is different, so it is necessary to research the population density of Siasia (S. nodus) based on differences in the substrate of the seagrass area in the waters of Saparua Island, Maluku Province, Central Maluku Regency. The highest population density value of Siasia (Sipunculus nodus) in Saparua Island waters is found in Siri-sori State and the lowest is in Paperu Country.

Abstract

The aims of this community service activity are for the community to know the nutritional levels of silpau from the coastal waters of Tial Country and how to use silpau as food from the sea. This community service activity was carried out as counseling to housewives in Lemon Hamlet, Tial Country, Central Maluku Regency. The population in this activity is the entire community of Tial Country with homemakers from Lemon Village as the sample. This community service activity is carried out in the form of counseling. After participating in community service activities, recognize and know about the potential of silpau as a nutritious alternative food ingredient, and how to process it.

Abstract

Nerita sp. is a type of gastropod that is commonly consumed by the people of Ambon Island, especially in the villages of Hutumuri and Latuhalat, and has the potential to be an alternative food source. However, its nutritional content has not been studied in detail. This research aims to analyze the proximate content, including moisture, ash, protein, fat, carbohydrates, and fiber, in Nerita maxima and Nerita costata from both locations. The study used a descriptive approach with random sampling techniques from the waters of Hutumuri Beach and Latuhalat Beach. Proximate analysis was conducted in the laboratory using the standard AOAC (Association of Official Analytical Chemists) methods.The analysis results show that at Hutumuri Beach, Nerita costata has a moisture content of 79.24%, ash 1.18%, protein 12.80%, fat 1.79%, carbohydrates 2.16%, and fiber 0.18%. Meanwhile, Nerita maxima has a moisture content of 81.30%, ash 1.10%, protein 13.90%, fat 1.72%, carbohydrates 1.66%, and fiber 0.19%. At Latuhalat Beach, Nerita costata has a moisture content of 76.80%, ash 1.48%, protein 17.02%, fat 2.75%, carbohydrates 1.49%, and fiber 0.20%. Whereas, Nerita maxima has a moisture content of 78.31%, ash 1.44%, protein 15.47%, fat 2.90%, carbohydrates 1.51%, and fiber 0.23%This research shows that Nerita costata and Nerita maxima from the waters of Latuhalat have higher protein and fat content compared to those from Hutumuri. This indicates that the more fertile and rocky water environment of Latuhalat supports better nutritional value, making these two species potential alternative food sources for the community.
