Abstract

Mangrove ecosystems are important in ecological, economic, and social aspects,especially for coastal communities. However, damage to mangrove ecosystemsdue to land-use changes for purposes such as settlements and fish ponds canthreaten their sustainability. This study aims to analyze the potential of themangrove ecosystem, apply the kao-kao model in silvofishery pond management,and analyze the potential of mangroves in increasing the income of the communityin Pematang Kuala Village, Teluk Mengkudu Sub-district, Serdang BedagaiDistrict, North Sumatra Province. The methods used include field surveys forvegetation analysis and interviews with Kelompok Usaha Bersama (KUB)Nelayan Sepakat members. Vegetation analysis was conducted in three zones:utilization zone I, II, and the protection zone. Each zone consisted of 5 plots,totaling 15 plots. Interviews were conducted with 27 respondents. The studyresults showed that the mangrove ecosystem in Pematang Kuala Village isdominated by Avicennia marina and Rhizophora mangle, with an important valueindex of 300 in both utilization and protection zones. In the protection zone, theShannon-Wiener diversity index was 0.95, indicating a low level of diversity.Based on the kao-kao system model, it was observed that the productivity of fishponds and fishermen's catch increased. Community income has significantlyincreased over the last five years, with an average net income of IDR 19,550,000every six months. The presence of mangroves also provides indirect benefits as acoastal protector from abrasion, with an estimated economic value of IDR247,950,000 per year.

Abstract

Desa Tanjung Rejo, Kecamatan Percut Sei Tuan, Kabupaten Deli Serdang, menghadapi masalah erosi pantai, banjir rob, pencemaran akibat polybag plastik di pembibitan mangrove, serta limbah kotoran sapi yang belum dikelola sehingga menimbulkan polusi, sementara ekonomi masyarakat, khususnya ibu rumah tangga, masih rendah. Untuk menjawab tantangan tersebut, kegiatan pengabdian masyarakat menghadirkan inovasi Pot Biodegradable Avicennia dari kotoran sapi dan serutan bambu sebagai solusi lingkungan sekaligus peluang ekonomi, yang menggantikan polybag plastik karena dapat terurai, memperkaya tanah, dan mendukung pertumbuhan bibit Avicennia penahan erosi. Metode kegiatan meliputi sosialisasi, pelatihan, pendampingan produksi, dan uji coba bibit dengan melibatkan kelompok PKK Desa Tanjung Rejo dalam semua tahapan, mulai dari pengumpulan bahan baku hingga pemanfaatan di pembibitan mangrove, sehingga memperkuat kapasitas masyarakat mengolah sampah lokal menjadi produk ramah lingkungan. Program ini diharapkan mengurangi ketergantungan plastik sekali pakai, mengatasi sampah organik, meningkatkan pendapatan rumah tangga melalui usaha kecil berbasis pot biodegradable, sekaligus mendukung mitigasi erosi, memperkuat ekonomi sirkular, dan berkontribusi pada pencapaian SDGs, sehingga inovasi ini tidak hanya mengatasi masalah lingkungan di Desa Tanjung Rejo tetapi juga membuka peluang kemandirian ekonomi masyarakat pesisir melalui pendekatan partisipatif dan berkelanjutan.
