Abstract

The source of sap for the palm sugar industry owns by forest farmers generally comes from sugar palm trees that naturally grow at cultivated lands in forest area. Therefore, the sustainability of the industry highly depends on the population of sugar palm trees and their sap production. This research aims to analyze the density, frequency, distribution pattern of sugar palm tree population, and their implication for the total sap production. The data was collected using nested rectangular plots with a sampling intensity of 2.5%, covering individual number of sugar palm trees, another tree species, altitude, land-slope, solar radiation intensity, air temperature and humidity, and daily sap volume. The result shows that the sugar palm trees naturally grow in clumped pattern, with the population density of the trees varies according to each altitude zone. The highest density (39.5 individuals/ha) can be found at an altitude of 500—700 m above sea level and has a solar radiation intensity of 57.6% under forest garden stands. Further, the natural regeneration process plays a pivotal factor in determining the frequency, density, and population of sugar palm tree. Low values of frequency and population density of sugar palm tree indicates that the natural regeneration process occurred suboptimal. Consequently, it affected the development of both the trees and therefore influencing the average sap produced. The population of sugar palm trees can increase naturally if the availability of the parental tree is well maintained and the farmers do not use pesticides in controlling weeds, which can also kill sugar palm seedlings.
