Abstract

Freshwater community in Lake Sentani comprise of 35 species including three endemic species, seven native species, eight anadromous fish and 17 introduced species. Two native species are Sentani Gudgeon (Oxyeleotris heterodon) and Snakehead Gudgeon (Giuris margaritacea). The survey aims to document the ecology and fish abundance of the gudgeons in Lake Sentani. Fish sampling was done passively by using gill nets with three different mesh sizes in five locations; Puai, Enandowai, Waena, Ayapo and Yahim. Substrate type, water vegetations, habitat depth and fish abundance were recorded each locations. Substrate preferences of the gudgeons are sand, mud and gravel, while O. heterodon was more abundance in sand mud substrate type. Moreover, water vegetation preference was different between O. heterodon and G. margaritacea. Sentani Gudgeon prefer habitat with dense water vegetations, while G. margaritaceus could be found in habitat with or without water vegetation. Theses two gudgeons were found in relatively the same habitat depth, up to 7 meters depth. O. heterodon and G. margaritacea had a very low abundance in the lake. It is important to conserve lake area from the edge  up to 7 meter depth that consist of sand, mud and gravel substrate types and dense water vegetation to ensure the population of these two gudgeons are abundance in Lake Sentani.   Key words: Ecology, Lake Sentani, relative abundance, O. heterodon, G. margaritacea.

Abstract

Papaya (Carica papaya L.) is a fruit with high nutritional value and significant potential to be developed into various processed food products. However, its utilization in the communities remains limited as papaya is generally consumed fresh or processed into simple dishes such as juice and vegetables. This community service activity aimed to increase public knowledge and skills in diversifying papaya-based food products by introducing the processing of papaya into a healthy dipping sauce that is free from artificial sweeteners and preservatives. The activity also sought to increase awareness of the economic potential of papaya-based processed products. It was conducted on August 9, 2025, in collaboration with the local community of Rhepang Muaif Tourism Village, at the kitchen pavilion of Isyo Hills Bird Watching Campsite. A total of 13 participants were involved, consisting of 8 youths, 3 middle-aged adults, and 2 elderly individuals. The implementation methods included socialization, hands-on training, and direct assistance in the preparation. The training utilized simple methods, common kitchen tools, and easily accessible ingredients. The results showed that participants were able to produce a spicy and healthy papaya-based dipping sauce that can be consumed with various snacks, such as boiled sweet potatoes, boiled bananas, fried bananas, and french fries. The product demonstrates potential economic value due to its affordability, health benefits, and marketability. Overall, the activity was well received, with participant satisfaction rates of 100%, indicating a positive response, successful implementation, and benefit to the community.
