Abstract

Amphibians are important indicators that are sensitive to environmental changes, so their presence is very important to assess the health of the ecosystem. The area of PT. Restorasi Ekosistem Indonesia Jambi Region has a diversity of habitats such as natural forests, bushes, and oil palm plantations. However, human activities such as land conversion into oil palm plantations cause damage to natural habitats and affect the presence and diversity of amphibians. Collecting data on species and habitat conditions is very important to support conservation efforts, considering the diversity of amphibians that act as bioindicators and important parts of the ecosystem. This research was conducted in January - February 2025 at PT. Restorasi Ekosistem Indonesia, Jambi Region using the Visual Encounter Survey (VES) and Capture Mark Recapture (CMR) methods combined with the line transect method of purposive sampling. There were 6 transect paths with 2 repetitions on each path. The data analysis used was the species diversity index, species evenness index, species richness index and community similarity index. The results of the study showed the diversity of amphibian species found in three types of habitats at PT. Restorasi Ekosistem Indonesia Jambi Region as many as 175 individuals, 22 species, 6 families. The value of species diversity (H ') in the bushes showed H '= 2.315 (moderate), natural forests showed H '= 2.273 (moderate), and oil palm plantations showed H '= 2.129 (moderate). The value of species evenness (E) in the bushes showed E = 0.885 (high), natural forests showed E = 0.839 (high), and oil palm plantations showed E = 0.857 (high). The value of species richness (Dmg) in the bushes showed E = 3.273 (low), natural forests showed E = 3.379 (low), and oil palm plantations 2.981 showed E = (low). In addition, the level of community similarity (IS) between habitats, which ranges from 11.65% - 16.29% which is included in the low category indicating differences in species composition in each habitat. Habitat conditions in three types of habitats at PT. Restorasi Ekosistem Indonesia Jambi Region still guarantee the growth and reproduction of amphibian species Habitat conditions support the life of amphibians, with air temperatures of 26.1˚C - 28.5˚C, humidity of 65% - 73%, air temperature of 25.5˚C - 28.5˚C, and air pH of 6.54 - 7.46. These data indicate that the research location has suitable habitat and temperature conditions to support the survival of amphibians in the area. Amfibi adalah indikator penting yang sensitif terhadap perubahan lingkungan, sehingga keberadaannya sangat penting untuk menilai kesehatan ekosistem. Kawasan PT. Restorasi Ekosistem Indonesia Wilayah Jambi memiliki keberagaman habitat seperti hutan alami, semak belukar, dan kebun sawit. Namun, aktivitas manusia seperti konversi lahan menjadi perkebunan kelapa sawit menyebabkan kerusakan habitat alami dan berpengaruh terhadap keberadaan serta keanekaragaman amfibi. Pengumpulan data tentang spesies serta kondisi habitat sangat penting untuk mendukung upaya konservasi, mengingat keberagaman amfibi yang berperan sebagai bioindikator dan bagian penting dari ekosistem. Penelitian ini dilaksanakan pada bulan Januari - Februari 2025 di PT. Restorasi Ekosistem Indonesia Wilayah Jambi menggunakan metode Visual Encounter Survey (VES) dan Capture Mark Recapture (CMR) dikombinasikan dengan line transect metode transek jalur secara purposive sampling. Jalur transek sebanyak 6 jalur dengan 2 kali pengulangan pada masing-masing jalur. Analisis data yang digunakan adalah indeks keanekaragaman spesies, indeks kemerataan spesies, indeks kekayaan spesies dan indeks kesamaan komunitas. Hasil penelitian menunjukkan keanekaragaman spesies amfibi yang ditemukan pada tiga tipe habitat di PT. Restorasi Ekosistem Indonesia Wilayah Jambi sebanyak 175 individu, 22 spesies, 6 famili. Nilai keanekaragaman spesies (H’) pada semak belukar menunjukkan H’ = 2,315 (sedang), hutan alami menunjukkan H’ = 2,273 (sedang), dan kebun sawit menunjukkan H’ = 2,129 (sedang). Nilai kemerataan spesies (E) pada semak belukar menunjukkan E = 0,885 (tinggi), hutan alami menunjukkan E = 0,839 (tinggi), dan kebun sawit menunjukkan E = 0,857 (tinggi). Nilai kekayaan spesies (Dmg) pada semak belukar menunjukkan E = 3,273 (rendah), hutan alami menunjukkan E = 3,379 (rendah), dan kebun sawit 2,981 menunjukkan E = (rendah). Selain itu, tingkat kesamaan komunitas (IS) antar habitat, yaitu berkisar antara 11,65% - 16,29% yang termasuk dalam kategori rendah yang mengindikasikan adanya perbedaan komposisi spesies di setiap habitat tersebut. Kondisi habitat pada tiga tipe habitat di PT. Restorasi Ekosistem Indonesia Wilayah Jambi masih menjamin pertumbuhan dan perkembangbiakan spesies amfibi Kondisi habitat mendukung kehidupan amfibi, dengan suhu udara 26,1˚C - 28,5˚C, kelembapan 65% - 73%, suhu air 25,5˚C - 28,5˚C, dan pH air 6,54 - 7,46. Data ini menunjukkan bahwa lokasi penelitian memiliki kondisi habitat dan suhu yang sesuai untuk mendukung keberlangsungan hidup amfibi di kawasan tersebut.
