Abstract

The sugar palm tree (Arenga pinnata) is a multipurpose tree because it has many benefits, both ecological and economic benefits. However, information on the relationship between the population size of sugar palm tree and environmental factors at which it grows is limited.This research aims to analyze the structure of the sugar palm tree population and its relationship with environmental factors where it grows at the area cultivated by the Harapan Baru III Forest Farmer Group in the Wan Abdul Rachman Grand Forest Park, Indonesia.The data was collected through vegetation surveys using nested rectangular plots with a sampling intensity of 2.5%, with a total of 17 nested sample plots. The data collected included the sugar palm tree population based on growth phase, trees species at the research location, altitude, land slope, soil pH, solar radiation intensity, air humidity, and air temperature. Data analysis by calculating density (D), frequency (F), simple linear regression, and Pearson correlation at a 5% significance level.The results showed that the density of sugar palm trees in the seedling phase was 11.8 individuals/ha, the young phase was 45.6 individuals/ha, the reproductive phase was 2.9 individuals/ha, and the post-productive phase was 2.9 individuals/ha.The frequency of sugar palm trees in the seedling phase is 0.2, the young phase is 0.5, the reproductive phase is 2.9, and the post-productive phase is 2.9.Then, the results of the regression and correlation analysis showed that the relationship between the population of sugar palm trees and the environmental factors where they grow had no significant effect.
