Abstract
Hevea brasiliensis was planted by the community of Simpang Kuta Buluh village and and Rumah Galuh Village because of its high economic value. The suitabilty land of Hevea brasiliensis 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 in Simpang Kuta Buluh village and Rumah Galuh Village, Sei Bingai Sub District, Langkat, North Sumatra, Indonesia. The survey method was conducted to collect soil samples in the field. Land suitability classification (LSC) for Hevea brasiliensis was evaluated based on the matching method. The Geographic Information System (SIG) 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 Hevea brasiliensis in Rumah Galuh Village were moderately suitable (S2) (86,97%) and marginal suitable (S3) (13,03%). There were no suitable (S1) and not suitable (N) classes were found in both villages. There were several limiting factors in land suitability evaluation in the area, namely: temperature (tc), erosion hazard (eh), and root zone medium (rc).
