Analisis Vegetasi Gewang (Corypha gebanga) di Kecamatan Boking Kabupaten Timor Tengah Selatan, Nusa Tenggara Timur

Abstract

This research explores the presence of the gebang population (Corypha gebanga) on Timor Island, specifically in the Boking District, Central Timor Regency, East Nusa Tenggara. Covering an area of approximately 24,382.04 Ha, the study projects that around 5-10% of this area serves as the habitat for gebang, playing a crucial role in the local community's life as a source of carbohydrates, vegetables, building materials, ropes, and woven crafts. The objective of this research is to assess the vegetation of gebang (Corypha gebanga) using the quadrant sampling method to analyze the identified vegetation composition and parameters such as density, relative density, frequency, relative frequency, dominance, and relative dominance. The research findings reveal that in the tree stratum, there is a density value of 0.02/0.01 ha, with a relative density of 100%, a frequency of 0.88 plots/9 plots, a relative frequency of 100%, dominance of 52.03 m2/900 m2, and a relative dominance of 100%. Similarly, in the Sapling Vegetation (Belta) stratum, the density value is 0.18/0.0025 ha, with a relative density of 100%, a frequency of 0.77 plots/9 plots, a relative frequency of 100%, dominance of 169.91 m2/225 m2, and a relative dominance of 100%. The understory vegetation stratum demonstrates diversity with 15 types of vegetation, where the highest density value is found in the gebang plant species at 0.97/0.0004 ha, with a relative density of 34.31%, a frequency of 0.55 plots/9 plots, and a relative frequency of 13.51%.
