Abstract

This study aims to identify the types of plants consumed by Sumatran elephants, the parts they eat, and the most frequently consumed plant species as a basis for managing Sumatran elephant feed in the Camp Elephant Response Unit (ERU) area of Bukit Barisan Selatan National Park. Data was collected through direct observation from 09:00 to 15:00 WIB, with observation locations determined using the purposive sampling method. The collected data included the types of food plants, the parts consumed, and the most frequently eaten plant species. Data analysis was conducted by calculating the Sorensen species similarity index and the foraging frequency. A total of 30 plant species were identified as elephant food, with 19 species found in open land habitats. The highest plant species similarity index based on habitat type was found on mixed habitats with swamp openings and cover, reaching 63.15%. The highest plant species similarity index based on individual elephants was recorded for Haryono and Renold at 80%. Eight plant species were identified as the most frequently consumed, including Brachiaria mutica, Cyperus kyllingia, Fimbristylis sp., Imperata cylindrica, Paspalum conjugatum, Panicum repens, Rynchospora corymbosa, and Scleria sp. Additionally, elephants only foraged eight plant species for other functions. Based on this study, Sumatran elephant only consume plant species that are abundant within their grazing habitat. The findings of this study can support the ex-situ conservation of Sumatran elephant by ensuring the continued availability of their food plants in the Camp ERU area of Bukit Barisan Selatan National Park.

Abstract

Arthropoda termasuk salah satu filum hewan dengan anggota paling banyak di antara filum hewan lainnya. Arthropoda mempunyai fungsi ekologi sebagai detritivor, dekomposer, herbivor, dan predator yang berguna untuk penyeimbang ekosistem serta dapat menjadi indikator kesehatan lingkungan. Penelitian ini dilakukan untuk mengetahui indeks keanekaragaman Shannon-Wiener (H’) Arthropoda yang terdapat di arboretum Institut Teknologi Sumatera (ITERA). Metode penelitian ini dilakukan dengan pengambilan sampel secara road sampling dengan menggunakan alat sweep net pada pagi dan sore hari selama empat hari dalam empat minggu. Sampel Arthropoda yang tertangkap diawetkan dalam alkohol 70% lalu diidentifikasi di Laboratorium Zoologi ITERA. Pada hasil penelitian diperoleh indeks keanekaragaman Shannon Arthropoda keseluruhan dengan nilai H’ = 3,619. Indeks ini termasuk tinggi karena sudah lebih dari tiga. Untuk di pagi hari, nilai indeks keanekaragaman yang diperoleh lebih tinggi dibandingkan di sore hari (H’ = 3,226 dan H’ = 3,000). Spesies Arthropoda yang paling dominan adalah Acrididae sp. Dengan nilai indeks dominansi 13,26%. Arthropoda yang paling dominan saat pagi hari adalah Conocephalus (10,53%) dan sore hari adalah Acrididae sp. (16,42%). Berdasarkan hasil penelitian, keanekaragaman jenis Arthropoda di Arboretum ITERA tergolong tinggi sehingga menandakan daya dukung di lingkungan arboretum ITERA masih cukup baik.
