Abstract
Penelitian ini bertujuan mengidentifikasi jenis tumbuhan paku (Pteridophyta) dan tingkat keanekaragamannya di Desa Terentang Baru, Kecamatan Batin XXIV, Jambi. Penelitian dilaksanakan pada Mei 2026 menggunakan metode survei eksploratif dengan teknik purposive sampling dan metode jelajah. Hasil penelitian menemukan 10 spesies tumbuhan paku yang tergolong dalam 9 genus dan 8 famili. Nilai indeks keanekaragaman Shannon-Wiener (H') sebesar 2,18 (kategori sedang) dan indeks kemerataan (E) sebesar 0,95 (kategori tinggi). Kondisi lingkungan berupa suhu 28°C, kelembapan 82%, pH tanah 6,4, dan intensitas cahaya 1.200 Lux mendukung pertumbuhan tumbuhan paku. Keanekaragaman tumbuhan paku di lokasi penelitian tergolong cukup baik dan berpotensi menjadi data dasar inventarisasi flora lokal serta konservasi keanekaragaman hayati. This study aimed to identify fern (Pteridophyta) species and determine their diversity level in Terentang Baru Village, Batin XXIV District, Jambi. Conducted in May 2026 using an exploratory survey, purposive sampling, and roaming methods, the study identified 10 fern species belonging to 9 genera and 8 families. The Shannon-Wiener diversity index (H') was 2.18 (moderate), while the evenness index (E) was 0.95 (high). Environmental conditions, including a temperature of 28°C, humidity of 82%, soil pH of 6.4, and light intensity of 1,200 Lux, supported fern growth. The findings indicate relatively good fern diversity and provide baseline data for local flora inventory and biodiversity conservation.
