Penelitian ini bertujuan untuk mengetahui besaran biomassa dan cadangan karbon di atas permukaan. Penelitian dilaksanakan selama 3 bulan dari Agustus hingga Oktober 2022 di Kawasan Mangrove Desa Sungai Kupah Kabupaten Kubu Raya. Penentuan lokasi penelitian dilakukan menggunakan metode systematic sampling with random start, kemudian dibentuk 20 plot pengamatan untuk mengamati diameter pohon mangrove dengan ukuran ≤ 4 cm. Penentuan biomassa mengacu pada metode non destructive dengan menggunakan persamaan allometrik. Berdasarkan hasil penelitian terdapat lima jenis tumbuhan mangrove yaitu Avicennia marina, A. alba, Sonneratia caseolaris, Nypa fruticans dan Rhizophora mucronata. Hasil penelitian menunjukkan jumlah biomassa dan cadangan karbon masing – masing yaitu 273,98 ton/ha dan 136,99 ton C/ha. Biomassa dan cadangan karbon tertinggi terdistribusi pada kelas diameter 34-43,99 cm sebesar masing – masing 73,52 ton/ha dan 36,76 ton C/ha, dan distribusi biomassa dan cadangan karbon tertinggi pada jenis A. marina dengan jumlah masing – masing 152,875 ton/ha dan 76,437 ton C/ha. \u0000Kata Kunci : biomassa, cadangan karbon, mangrove, sungai kupah.","PeriodicalId":484949,"journal":{"name":"Jurnal Bios Logos","volume":"13 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138602164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is important to do to find suitable biological control agents to reduce the impact of using synthetic pesticides. This research was conducted to look at the diversity and abundance of entomopathogenic fungi and their host insects, so that potential entomopathogenic fungal and pest species were identified in the rice fields of Kembang Mertha Village. The results obtained were four species of host insects, namely Leptocoarisa oratorius, Schotinopara coarctata, Ricelia dorsalis and Nilaparvata lugens, and three species of entomopathogenic fungi, namely Beauveria bassiana, Metarhizium sp. and Hirsutella sp.. The host insect diversity indices in the medium category were S. coarctata (1.10) and N. lugens (1.04) and for entomopathogenic fungi, the three fungal species found were in the medium category respectively B. bassiana (1.31), Metarhizium sp. (1.07) and Hirsutella sp. (1.05). The highest abundance index values for host insects were S. coarctata (84.62%) and N. lugens (50%), while for pathogenic fungi were Hirsutella sp. (43.73%).","PeriodicalId":484949,"journal":{"name":"Jurnal Bios Logos","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135359011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
