Desa Bawah Layung Kecamatan Kurau Kabupaten Tanah Laut Provinsi Kalimantan Selatan merupakan desa pesisir dimana terdapat sumber daya ekosistem mangrove yang besar dan terletak di muara Sungai Bawah Layung. Potensi mangrove yang sangat besar di pesisir pantai Layung memerlukan pengelolaan yang baik dan perlu dilakukan perlindungan terhadapnya. Penelitian ini perlu adanya kajian mendalam tentang potensi simpanan karbon pada vegetasi mangrove di wilayah Pesisir Bawah Layung. Sehingga, data tersebut dapat menjadi dasar kegiatan pengelolaan secara berkelanjutan khususnya untuk mitigasi perubahan iklim wilayah pesisir Kalimantan Selatan. Perolehan data dilakukan survei ke lapangan, studi literatur terkait dengan lokasi dan pengumpulan data sekunder, sedangkan pemilihan lokasi pengambilan sampel menggunakan metode purposive sampling. Tujuan penelitian ini mengetahui jenis mangrove, jumlah biomassanya dan menganalisis besaran stok karbon biru (blue carbon) yang tersimpan. Hasil penelitian didaptkan 3 jenis yaitu Avicennia marina, Exoecaria agallocha, Rhizopora mucronata. Hasil jumlah biomassa atas Permukaan total nilai sebesar 141,76 Ton/ha dan bawah Permukaan sebesar 52,45 Ton/ha. Nilai Stok Karbon ekosistem mangrove memiliki total 66.031,4 Ton C yang terbagi atas karbon atas permukaan sebesar 66,63 Ton C/ha dan 24,65 Ton C/ha.

Kata Kunci: Ekosistem Mangrove, Biomassa, Stok Karbon Biru (blue carbon)

Abstract

Bawah Layung Village, Kurau District, Tanah Laut Regency, South Kalimantan Province, is a coastal village where there are large mangrove ecosystem resources and is located at the mouth of the Bawah Layung River. The huge potential of mangroves on the coast of Layung requires good management and needs to be protected against them. This research needs an in-depth study of the potential for carbon storage in mangrove vegetation in the Lower Layung Coastal area. Thus, the data can be the basis for sustainable management activities, especially for climate change mitigation in coastal areas of South Kalimantan. Data acquisition was carried out surveys to the field, literature studies related to location and secondary data collection, while the selection of sampling locations used the purposive sampling method. The purpose of this study is to determine the type of mangrove, the amount of biomass and analyze the amount of blue carbon stock stored. The results of the study were obtained 3 types, namely Avicennia marina, Exoecaria agallocha, Rhizopora mucronata. The total biomass yield of the total surface value is 141.76 tons / ha and the subsurface is 52.45 tons / ha. The Carbon Stock Value of mangrove ecosystems has a total of 66,031.4 Tons C which is divided into 66.63 Tons C / ha and 24.65 Tons C / ha.
