【 摘 要 】

Pinus (Pinus merkusii) is commonly found in North Sumatra Forest. Community of Telagah Village, Sei Binge Sub District, Langkat, North Sumatera, generally manage the land with agroforestry system. Pinus is the one of agroforestry constituent in the community land in Telagah Village. This study aimed to analyse the suitability of the land for pinus in Telagah Village Sei Bingai Sub District, Langkat District, North Sumatra, Indonesia. This research was conducted on May to September 2018. The survey method was conducted to collect soil samples in the field. Spasial analysis for pinus land suitability was evaluated based on the matching method. The reference and criteria were adopted from the Land Suitability for Agricultural Plants by the Centre for Soil and Agroclimate Research, Bogor-Indonesia. The Geographic Information System (GIS) was used to map the actual and potential land suitability in Telagah Village. The results showed that the actual land suitability classes for pinus in this area were moderately suitable (S2) (97.26%) and marginal suitable (S3) (2.74%). The potential land suitability classes for pinus in this area were Suitable (S1) (52.04), moderately suitable (S2) (46.04%) and marginal suitable (S3) (1.92%) in Telagah Village. The temperature (tc) and erosion hazard (eh) were the dominant of limiting factor in this area.
