Abstract

Gambier has high economic value, but it has not been cultivated intensively in Indonesia. Plant area and production of gambier still fluctuate from year to year. Pakpak Bharat is the largest gambier-producing region in North Sumatra. The factors that directly and indirectly influence the production of dried gambier sap in Pakpak Bharat District were analyzed using the linear regression model with the intermediate or intervening variable. The results showed that the area of productive plants, the use of fertilizers, and the experience in farming had a positive and significant influence on the amount of harvested gambier leaf, the types of seeds, and the use of pesticides. However, the age of productive plants have a negative and significant influence. Meanwhile, the number of productive plants has a positive influence and the number of cultivation labors has a negative influence, although it is not significant. The number of processing labors has a positive and significant influence on the production of dried gambier sap; while the amount of harvested gambier leaf has a positive but not significant influence. Variables influencing the amount of harvested gambier leaf cannot influence the production of dried gambier sap indirectly through the mediation of the amount of harvested gambier leaf.
