Abstract

Abstract Silvofarmaka system is optimizing land management by combining forestry plants and medicinal plants. The purpose of this research is to study the potential of Turkey (C. longa), Curcuma (C. xanthorrhiza ) and Pegagan (C. asiatica ) under Mindi (M. azedarach ) and Sentang (A. excelsa ) in the silvofarmaka system. There are 60 seedlings for each species planted under Mindi and Sentang under 5 years, and there is no shade tree as a control. We measured the diameter and size of the Turmeric and Curcuma rhizomes, and the number of Pegagan leaves. The results showed that the average diameter of Turmeric (9.225 cm) and Curcuma (15.125 cm) under the shade of the tree was higher than under the shade of the tree. The difference in growth may be due to the intensity of sunlight. Turmeric, Curcuma, and Pegagan can grow in the shade of light. While the intensity of sunlight in this study is low, namely 304,536 lux (without the shade of a tree), 63.45 (under Mindi), and 47.72 (under Sentang). This lower intensity of sunlight causes lower biomass (diameter and leaves). The medicinal plants need more light intensity to grow optimally so that further activities (e.g. pruning and thinning) are needed..
