Abstract

Mangroves are a type of vegetation found in tropical coastal areas. In general, mangrove vegetation thrives in sloping coastal areas or near river estuaries and beaches that are protected from waves. The physical function of mangrove forests is to keep the coastline stable, protect the coast from erosion, reduce storms and waves, and catch sediment, while the biological function of mangroves is as a spawning place or residence, shelter for shrimp, crabs, shellfish, and other animals. Research on Mangrove Plant Community Structure in the Kwala Indah Village Area was carried out in August–November 2023 with the aim of determining mangrove types, mangrove diversity and uniformity, dominance, the Important Value Index (INP), and mangrove canopy cover in Singai Apung Village. The method used to observe the community structure of mangrove plants is to use the quadrant transect method by analyzing species density, relative density, species frequency, relative frequency, species dominance, relative dominance, and important value index at the tree level. , saplings and seedlings, as well as canopy cover. Based on the research results, 10 species were found, namely Avicennia alba, Avicennia lanata, Bruguiera cylindrica, Bruguiera sexangula, Excoearia agallocha, Lumnitzera littorea, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Xylocarpus granatum. Rhizopora mucronata, which has INP, diversity in the medium category, and uniformity in the high category, has the highest dominance in Rhizophora mucronata. Canopy cover is in the dense category.

Abstract

Aras Village is a village in Air Putih District, Batu Bara Regency, North Sumatra Province. The people who live in the Aras Village area are farmers, fish cultivators and traders. The partner's problem is that they have never received training in making independent feed and evaluating their cultivation business. So far, fish farmers in Aras Village still rely on factory-made feed, causing the price of the feed product to be very high, reaching 70% of the total production costs and they cannot evaluate their business. The aim of community empowerment activities is to assist fish farmers in managing and increasing fish farmers' income in managing catfish cultivation. The priority aim of community service carried out by lecturers is to improve the economy. The stages of the implementation method used are outreach and training to the community on how to make good and healthy fish food. Socialization, training and assistance to the catfish farming community on how to evaluate catfish cultivation businesses by calculating income, expenses, BEP, B/C ratio and NPV (overcoming management problems). Evaluation of program implementation is carried out every time an activity is carried out, such as socialization, training and mentoring. Socialization and training on making independent feed and evaluating fisheries businesses is going well in Aras Village, Air Putih District, Batu Bara Regency. The program evaluation results show that as many as 80% of cultivator groups can know how to make feed independently and evaluate their efforts.

Abstract

Produksi hasil tangkapan Ikan Kembung yang di daratkan di PPN Sibolga Sumatera Utara rata-rata mengalami fluktuasi setiap tahunnya. Oleh karena itu, perlu dilakukan analisis hasil tangkapan Ikan Kembung untuk mengontrol tingkat eksploitasi dan menciptakan kegiatan operasi penangkapan yang efektif agar pemanfaatan sumberdaya Ikan Kembung dapat berjalan secara optimal dan berkelanjutan. Metode Pengambilan Data menggunakan metode survey untuk mendapatkan gambaran yang dapat mewakili potensi dan tingkat pemanfaatan Ikan Kembung di PPN Sibolgan Sumatera Utara Analisis data yang digunakan meliputi produksi penangkapan Ikan Kembung, tangkap per satuan upaya, potensi lestari dan effort optimum, total allowble cath (TAC), tingkat pemanfaatan dan pengupayaan. Hasil tangkapan tertinggi terjadi pada tahun 2018 (213,94) ton. Hasil tangkapan ikan kembung terendah terjadi pada tahun 2021 (94,64} ton. Nilai CPUE tertinggi terjadi pada tahun 2020 (0,62) ton/trip. Nilai CPUE terendah terjadi pada tahun 2017 (0,43) ton/trip. Potensi lestari (MSY) sumberdaya Ikan kembung di perairan Sibolga dalam kurun waktu 6 tahun terakhir sebesar 337,59 dengan effort optimum sebesar 1410 trip. tingkat pemanfaatan rata-rata Ikan Kembung pada tahun 2017-2022 sebesar 43% berada pada kategori padat menengah (Moderatedly exploited) dan tingkat pengupayaan 20%. tingkat pemanfaatan Ikan Kembung (Rastrelliger sp.) telah mencapai kategori rentang berkembang.
