Ecological Aspects and Regeneration of Sugar Palm in the Sasak Community Gardens of Kekait Village, West Nusa Tenggara, Indonesia

Abstract

Sugar palm (Arenga pinnata) is one kind of palm that has multiple benefits on the Sasak community of Kekait Merr.Village. Despite its benefit, the information of sugar palm is barely unknown since the farmers depend on the nature cultivation The Research aimed to analyze ecological aspects: composition, structure, the vegetation distribution, . which includes the rate of regeneration and spatial distribution of sugar palm in the Sasak community garden in Kekait Village, West Lombok Regency, West Nusa Tenggara Province. The methods employed in the research is a single plot method with randomly selected. Obtained data are being analyzed quantitatively and qualitatively. The research successfully identified 68 species of 30 families plant. The majority of species are Meliaceae and Anacardiaceae families. The highest IVI from seedlings, saplings, poles, and trees are A. pinnata (52.09%), T. cacao (22.72%), G. gnemon (91.49%), D. zibethinus (80.19%). The vegetation structures showed a well-developed structure. The vegetation distribution in the farmers' garden indicated a clustered pattern within three strata; B, C, and D strata. The regeneration level of A. pinnata categorized as fair sustainable with a clustered distribution pattern. The pattern is affected by the reproduction and distribution of A. pinnata seeds which carried out by Rinjani weasel (Paradoxurus hermaphroditus rinjanicus).

The Potential of Aren (Arenga pinnata (Wurmb) Merr.) Stands in Cimantaja Resort, Mount Halimun Salak National Park

“…The number of seedling individuals shows the largest number among other regeneration levels, because seedlings are the first level of growth that comes from the spread of plant seeds that fall to the forest floor [8]. The decrease in numbers between regeneration levels occurs due to competition for nutrients and growing space that occurs naturally.…”

POLA SEBARAN POPULASI AREN (Arenga pinnata) BERDASARKAN KELAS PERTUMBUHAN DI DESA SANGTANDUNG KECAMATAN WALENRANG UTARA KABUPATEN LUWU

“…Menurut (Haryoso et al 2020), pola penyebaran aren dipengaruhi oleh beberapa faktor yaitu ketersediaan makanan, subtrat sebagai habitat hidup, pengaruh faktor ekologi seperti fisika, kimia dan lingkungan serta strategi adapatasi dan interaksi biologis antar populasi yang ada dalam komunitas tersebut. Untuk mengetahui pola penyebaran populasi aren dalam suatu komunitas digunakan perhitungan dengan menggunakan indeks pola penyebaran Morisita dan indeks tersebut diuji dengan menggunakan uji statiska yaitu sebaran Chi Square.…”
