Abstract

Paya Geli Village is a village located in Sunggal District, North Sumatra Province and has good geographical conditions for the development of the agricultural sector, especially freshwater fish. The availability of abundant and easily available clean water has become a strength in the development of the freshwater fish industry in this village. The process of eel cultivation which does not require a lot of equipment and care as well as a large area of ​​land is the main attraction in terms of its development potential. Paya Geli village community. The people of Paya Geli Village only use a conventional cultivation system where the eels are simply left in a mud bath and fed with leftover food. The use of the conventional system will not only have a small impact on productivity but will also encourage a bad and dirty paradigm for the eel consumer society. The solution to this problem is the use of eel cultivation methods with clean water media and partial harvests which will not only increase productivity but also make it easier to control and harvest according to the specifications desired by the market. It is hoped that this service activity will not only increase the productivity of eel cultivation but also become a new source of driving the economy of the Paya Geli Village community and expand employment opportunities through eel farming entrepreneurial activities.

Abstract

Estuaries function as sediment deposition zones that provide essential substrates for mangrove development. Consequently, estuaries and mangroves constitute integral components of coastal ecosystems. The mangrove ecosystem in the Belawan Estuary, North Sumatra Province, is increasingly threatened by rapid urban expansion in Medan City. This study aimed to assess mangrove biodiversity, structural characteristics, and ecological status in the Belawan Estuary. Field surveys were conducted in November 2023 across 28 sampling stations representing seaward, middle, and landward sections of the estuary. Vegetation data were analyzed using density, diversity, evenness, dominance, and Importance Value Index (IVI). A total of 26 mangrove species were recorded, comprising 21 true mangrove species and 5 associated species. The most widely distributed species were Avicennia marina, Avicennia lanata, and Nypa fruticans. Mangrove density ranged from 533 to 2,733 ind ha⁻¹, with an average of 1,420 ind ha⁻¹. Shannon–Wiener diversity values ranged from 0.04 to 1.95, indicating relatively low diversity in several landward stations dominated by N. fruticans. Although the overall condition of mangroves in the Belawan Estuary is classified as good, the ecosystem remains highly vulnerable to land-use conversion under the revised spatial planning framework. Strengthening conservation-oriented spatial policy is therefore essential to ensure long-term ecosystem sustainability.
