Abstract. Rahmawaty, Frastika S, Rauf A, Batubara R, Harahap FS. 2020. Land suitability assessment for Lansium domesticum cultivation on agroforestry land using matching method and geographic information system. Biodiversitas 21: 3683-3690. Lansium domesticum is one of the multipurpose tree species (MPTS) and is commonly found on agroforestry lands in Sumatra. This study aimed to evaluate the actual land suitability classes for L. domesticum and to map the potential land suitability for the species using matching method and geographic information system (GIS). The study was conducted in Sei Bingai Sub-district, Langkat District, North Sumatra, Indonesia. A survey was conducted to collect soil samples based on land units. Land unit information was obtained by overlaying soil map, land-use map, and slope map. Land suitability was evaluated based on the matching method and GIS was used to map the distribution of land suitability. The results showed that both the actual and potential land suitability classes based on matching approach for L. domesticum were moderately suitable (S2) which accounted for 88.95% of total land and marginally suitable (S3) which accounted for 11.05%. Availability of water (wa), erosion hazard (eh), root-zone medium (rc), oxygen availability (oa), and nutrient retention (nr) were the dominant limiting factors in this area. The most difficult constraints to manage were root-zone medium and water availability. The results of this study suggest that the development of L. domesticum in Sei Bingai is possible although it requires some land improvements to deal with the limiting factors.

Lack Of Knowledge

Abstract: Most farmers are do’nt know what plants are suitable for planting on their land. This is due to the lack of knowledge of farmers regarding the suitability of land with the growing requirements of a crop. The lack of knowledge of farmers and the community about the evaluation of land suitability causes the cultivated plants do not produce optimally, because the conditions required by these plants are not in accordance with the conditions of the land that supports the growth of these plants. Seeing the importance of the process of selecting plants based on land suitability, while determining the selection of plants is still done only by looking at the experience of farmers who have not been tested. So the authors feel the need to make research to determine plants on land based on land suitability and plant growth requirements. The Analytical Hierarchy Process method is very suitable to be used to calculate the priority weight of each criterion because it is objective, which will later be used as a reference ranking by the TOPSIS method. With this research, it can determine the estate crops that will be planted on a land based on the level of land suitability and the requirements for growing plants that are alternative precisely, accurately and dynamically. Keywords: DSS, AHP, TOPSIS Abstrak: Kebanyakan Petani masih banyak yang belum mengetahui tanaman apa yang cocok ditanaman di lahannya. Hal ini disebabkan karena kurangnya pengetahuan petani mengenai kesesuaian lahan dengan persyaratan tumbuh suatu tanaman. Lemahnya tingkat pengetahuan petani dan masyarakat tentang evaluasi kesesuaian lahan menyebabkan tanaman yang dibudidayakan tidak berproduksi optimal, karena syarat yang dibutuhkan tanaman tersebut belum sesuai dengan kondisi lahan yang mendukung pertumbuhan tanaman tersebut. Melihat pentingnya proses pemilihan tanaman berdasarkan kesesuain lahan, sedangkan penentuan pemilihan tanaman masih dilakukan hanya berdasarkan dengan melihat pengalaman petani yang belum teruji. Maka penulis merasa perlu membuat penelitian untuk menentukan tanaman pada lahan berdasarkan kesesuain lahan dan persyaratan tumbuh tanaman. Metode Analytical Hierarchy Process sangat cocok digunakan untuk menghitung bobot prioritas dari tiap kriteria karena bersifat obyektif, yang nantinya menjadi acuan perangkingan yang dilakukan dengan metode TOPSIS. Dengan adanya penelitian ini, maka dapat menentukan tanaman perkebunan yang akan ditanam pada suatu lahan berdasarkan tingkat kesesuaian lahan dan persyaratan tumbuh tanaman yang menjadi alternatif secara tepat, akurat dan dinamis.

Peanut is a plant that has an important role in land and has a high selling value. Therefore it is necessary to take appropriate steps to develop peanut cultivation in the Panasen Sub-watershed by knowing the level of land suitability. The problems faced by the community are 1) lack of interest in the community to plant peanuts, 2) land-use change from agricultural land to lodging land 3) land evaluation has never been carried out for peanut plants in the area. The study used a land unit approach supported by soil analysis, plant growth requirements, and matching. The results showed that the research area was classified as suitable for peanut plants with a suitability class S2 (quite suitable) with a total of 4 land units, namely S2rfns (945.41 ha), S2sn (1675.15 ha), S2srn (938.05 ha), S2sn (13.45 ha) and class suitability of S3 (according to marginal) with 2 land units, namely S3s (12.95 ha), S3s (15.67 ha). The limiting factors for suitability class S2 are root media (r), nutrient retention (f), nutrient availability (n) and terrain (s). The limiting factor for suitability class S3 is the field (s). The limiting factor for N1 land suitability is nutrient availability (n), root media (r) and terrain (s). The limiting factors for conformity class N2 are the field (s) and the rooting medium (r).
