Abstract
Hevea brasiliensis and Aquilaria malaccensis were planted by the community because of its high economic value. The suitabilty land of Hevea brasiliensis and Aquilaria malaccensis in North Sumatra Province are important, especially in the agroforestry land that are often planted by the community. This study aimed to map the suitability of the land for Hevea brasiliensis and Aquilaria malaccensis in Simpang Kuta Buluh village, Sei Bingai Sub District, Langkat District, North Sumatra, Indonesia. The survey method was conducted to collect soil samples in the field. Land suitability classification (LSC) for Hevea brasiliensis and Aquilaria malaccensis was evaluated based on the matching method. The Geographic Information System (GIS) was used to map the land suitability both actual and potential land suitability. The results showed that the actual land suitability classes for Hevea brasiliensis in Simpang Kuta Buluh Village were moderately suitable (S2) (52,91%) and marginal suitable (S3) (47,09 %). The actual land suitability classes for Aquilaria malaccensis in Simpang Kuta Buluh Village also the same with Hevea brasiliensis, namely: S2 and S3.There were several limiting factors in land suitability evaluation in the area. The limiting factors for Hevea brasiliensis namely: temperature (tc) and root zone medium (rc). The limiting factors for Aquilaria malaccensis namely: root zone medium (rc).
