Abstract: Meiofauna adalah kelompok fauna asosiasi mangrove yang berkontribusi sebagai bioindikator. Tujuan penelitian ini adalah untuk menganalisis struktur komunitas meiofauna dan keterkaitannya dengan karakteristik fisika-kimia pada ekosistem mangrove alami di Telaga Tujuh, Selat Malaka. Pengambilan data dilakukan pada Agustus 2022 pada tiga stasiun. Sampel meiofauna diambil menggunakan pipa paralon (diameter: 5 cm; tinggi: 10 cm). Sampel kemudian disaring menggunakan ayakan bertingkat dan diwarnai lalu diidentifikasi menggunakan mikroskop binokuler. Parameter suhu, salinitas, pH sedimen diukur secara in-situ dan Eh, C-Org, TOM, NO3, PO4 dianalisis di laboratorium. Kerapatan mangrove dan kelimpahan meiofauna dianalisis menggunakan analisis korespondensi. Hasil menunjukkan komunitas meiofauna terdiri dari 7 filum, dengan Platyhelminthes sebagai kelompok dominan. Rhizophora apiculata berkorelasi dengan ordo Enoplida dan Macrostomida, sedangkan Bruguiera gymnorrhiza berasosiasi dengan Nemertodermatida dan Lituolida.
Meiofauna are a group of fauna associated with mangroves and serve as bioindicators. This study aims to analyze the meiofauna community structure and its relationship with the physico-chemical characteristics of the natural mangrove ecosystem in Telaga Tujuh, Malacca Strait. Data collection was conducted in August 2022 at three stations. Meiofauna samples were collected using a PVC corer (5 cm diameter, 10 cm height), sieved through graded mesh screens, stained, and identified under a binocular microscope. Temperature, salinity, and sediment pH were measured in situ, while redox potential (Eh), organic carbon (C-Org), total organic matter (TOM), nitrate (NO₃), and phosphate (PO₄) were analyzed in the laboratory. Mangrove density and meiofauna abundance were examined using correspondence analysis. The results identified seven meiofauna phyla, with Platyhelminthes as the dominant group. Rhizophora apiculata correlated with Enoplida and Macrostomida, while Bruguiera gymnorrhiza was associated with Nemertodermatida and Lituolida.
