Abstract

Sheoak (Casuarina equisetifolia L) is a species of monotypic taxa that has grown naturally in coastal Bengkulu Province. However, the various dynamics occurring in the coastal areas have disrupted the habitat of this species, affecting the structure and composi-tion of the vegetation. This research aims to analyze the structure and composition of vegetation in sheoak habitat in three conser-vation areas. The vegetation data was collected by line transect plot method. The analysis shows that sheoak stands form an invert-ed curve J in three conservation areas although they were not perfect due to the low density of poles which can be caused by dis-turbances that come from nature and human activity. Vegetation composition in sheoak habitat was composed by 36 species of 27 plant families consisting of shrubs and trees. Sheoak dominated the three areas only at the rate of tree growth while the growth rates of seedlings, saplings and poles were dominated by nyamplung (Calophyllum inophyllum) so the dominance of sheoak can be replaced with nyamplung. Sheoak also supported better habitat for other plant species to grow that showed diversity index value 1.4 to 1.9.

Abstract

Sistem repong damar merupakan salah satu kearifan lokal dalam sistem budidaya hutan yang berada di Desa Pahmungan, Provinsi Lampung, dimana pohon utama yang ditanam adalah pohon damar (Shorea javanica) diselingi dengan berbagai jenis tumbuhan lainnya. Masyarakat yang menghuni kawasan disekitar repong damar menggunakan banyak jenis tumbuhan sebagai pemenuhan kebutuhan hidupnya.  Penelitian ini telah dilakukan pada bulan Mei-Juni 2018 dengan tujuan untuk mengidentifikasi jenis tumbuhan yang dimanfaatkan sebagai bahan pangan oleh masyarakat Desa Pahmungan. Data dikumpulkan melalui wawancara langsung terhadap masyarakat dengan teknik snowball sampling serta observasi lapang. Hasil penelitian menunjukkan bahwa didapatkan 50 jenis tumbuhan dari 28 famili yang dimanfaatkan sebagai bahan pangan. Famili tertinggi yaitu Myrtaceae sebesar 21%. Pemanfaatan bagian tumbuhan yang paling banyak digunakan adalah bagian buah sebesar 76%. Pemanfaatan pohon sebagai bahan pangan yang berada di agroforestri repong damar harus diimbangi dengan pengelolaan dan sistem budidaya yang tepat agar memiliki nilai manfaat berkelanjutan bagi generasi yang akan datang.

Abstract

The estuarine of Sungai Hitam in Bengkulu City represents a sandy terrestrial ecosystem characterized by a diverse assemblage of ground cover species, which collectively contribute to the ecological functionality of the immediate environment. This study aimed to identify the structural characteristics, species composition, and species diversity of the ecosystem's constituent flora. Fieldwork was conducted from January to February 2018. Data collection involved the systematic placement of 1m x 1m quadrat plots at 20m intervals. Subsequent data analysis utilized the Important Value Index (IVI) and Shannon-Wiener Diversity Index (H') equations. The findings revealed the presence of 79 species distributed across 22 families of ground cover plants. Sphagneticola trilobata (L.) was identified as the dominant species within this area, attributed to its robust adaptive capabilities and invasive characteristics. Despite this dominance, the overall species diversity was classified as high, evidenced by a diversity index value of 3.21. This high index signifies a relatively stable community structure and considerable ecological resilience against environmental disturbances.

Abstract

Mangrove seedling are vulnerable to pest disturbances that can affect stand health and regeneration success. This study aimed to identify leaf-eating insect species and analyze pest attack incidence and damage intensity on Rhizophora apiculata and Bruguiera gymnorhiza in Pantai Panjang Nature Tourism Park. Observations were conducted over four months (March–June) using direct field observation methods on established sampling plots. Four leaf-eating insect pest species were recorded: Attacus atlas (Atlas Moth), Metisa plana and Mahasena corbetti (Bagworms), and Oxya japonica (Migratory Grasshopper). Pest attack incidence on R. apiculata was consistently higher than on B. gymnorhiza throughout the observation period, with the highest values recorded in June. Damage intensity on both species ranged from 15–23%, peaking in April–May, and was classified as very light and light on leaf damage scoring criteria. These findings are expected to serve as a reference for developing appropriate pest monitoring and management strategies to support the sustainability of mangrove ecosystems in Pantai Panjang Nature Tourism Park.
