The eruption of Mount Sinabung produced volcanic ash. These ashes cover agricultural land in its vicinity, causing a decrease in agricultural production. One of the agricultural products around Mount Sinabung is orange, previously they are one of the largest sources of income for the farmers. This study aimed to evaluate the land suitability for orange plants (Citrus sinensis L) after the eruption of Mount Sinabung. Soil samples were taken based on 4 cardinal directions (North, East, South, and West), each at a 3-5 km radius, 5-7 km, and 7-10 km. Soil samples were taken from the depth of 0-20 cm and 20-40 cm. The soil was analyzed for soil texture, soil pH, CEC, organic C, total N, available P, and exchangeable bases (Ca, Mg, K, and Na). Evaluation of land suitability was done by 2 methods, the qualitative and quantitative methods by applying rating for each parameter. Results show that the Land evaluation range from S2 (Suitable), S3 (Marginally Suitable), and N (Not Suitable) with limiting factors such as slope, soil depth, soil texture, soil pH, and soil fertility. The results of the land suitability evaluation using these two methods have some differences because they have different land suitability criteria. Overall, the suitability area of the S2 class is 7,929.79 hectares located in Kuta Gugung, Kurbakti, and Kuta Mbaru, the area of the S3 conformity class is 13,038.29 hectares located in Namanteran, Sukandebi, Beganding, and Tiganderket and the area of the suitability class N is 7,207.49 hectares in Kuta Kepar, Kuta Tonggal, and Payung.
