Abstract

Batu Ampar Village is a coastal area included in the administrative area of Batu Ampar District, Kubu Raya Regency. The mangrove area of Batu Ampar Village reaches 58,953 ha and is a habitat for gastropods. Gastropods are a group of shelled animals that inhabit the mangrove area. The use of mangrove wood as charcoal in Batu Ampar Village causes damage and affects the life of gastropods. This study aims to examine the structure of the gastropod community in the mangrove area of Batu Ampar Village. The study was conducted on October 26, 2024 using a 1 x 1 m transect with a purposive random sampling method. Based on the results of gastropod identification in the mangrove area of Batu Ampar Village, West Kalimantan, 5 gastropod families were found consisting of Littorinidae, Muricidae, Ellobiidae, Potamididae, and Neritidae. The most commonly found species is Nerita balteata with a total density of 4 ind/m2. The diversity index (H"™) of gastropods is 0.73 and is classified as low. The gastropod uniformity index (E) is 0.59 and is classified as moderate. The gastropod dominance index (C) is 0.4 so that no species dominates.

Abstract

Kabupaten Kubu Raya, Kalimantan Barat mempunyai total luasan area ekosistem mangrove mencapai 44.625,76 hektar. Ekosistem mangrove memiliki potensi besar sebagai sumber metabolit sekunder yang berperan penting dalam mekanisme adaptasi terhadap tekanan lingkungan. Kawasan ekowisata Borneo Bahari yang berada di Desa Sungai Kakap, Kabupaten Kubu Raya merupakan area pesisir yang ditumbuhi oleh berbagai jenis mangrove seperti Acanthus ilicifolius, Avicennia marina, dan Sonneratia caseolaris. Namun, belum ada kajian mengenai kandungan metabolit sekunder pada mangrove di kawasan ekowisata Borneo Bahari. Penelitian ini bertujuan untuk mengidentifikasi kandungan senyawa metabolit sekunder pada daun Acanthus ilicifolius, Avicennia marina, dan Sonneratia caseolaris. Metabolit sekunder dari ketiga jenis mangrove diekstraksi dengan pelarut etanol menggunakan metode maserasi. Hasil menunjukkan bahwa ekstrak etanol A. ilcifolius mengandung flavonoid dan saponin. Mangrove A. marina mengandung alkaloid, flavonoid, saponin, dan steroid. Jenis S. caseolaris menunjukkan ekstrak mengandung senyawa flavonoid, saponin, dan steroid. Temuan ini menjadi dasar awal dalam eksplorasi lebih lanjut seperti potensi bioaktivitas metabolit sekunder dari mangrove di wilayah tersebut.
