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.

Taking the connecting band of urban integration as study area, based on an appropriate index system, the method of Entropy Weight-Geographic Information System (GIS) was employed to carry out the land suitability assessment at a regional scale. Shenyang Irrigation Area (SIA) was taken as the practical example. It was found that the method was reasonable to assess the land suitability and the assessment results can be used to support land planning in a flexible way.

Land suitability assessment is an essential step for the planning and development of land use. This study aims to determine suitable lands for organic farming using an integration of the Geographic Information System and the Decision-Making Trial and Evaluation Laboratory method. Geographic Information System is a flexible and practical framework to assess and map the different criteria, including climatic factors, internal soil characteristics, and topographic features. The Decision-Making Trial and Evaluation Laboratory method is employed to identify the weights of the proposed factors. We investigated the data of 126 soil profiles covering 23220 hectares of land, located in Tamdao district, Vinh Phuc province, in the north of Vietnam. The results revealed that the proportion of land currently highly suitable for organic farming is 25.93% (6020.22 hectares), while the amount of land that is marginally suitable is 6.38% (1481.82 hectares). The amount of land that is moderately suitable for organic farming is 67.69% (15718.08 hectares). Therefore, the proposed method can improve planning and decision-making regarding land that is suitable for cultivation. Future research may deal with a more significant number of selected criteria with different methods, such as Entropy, Analytic Hierarchy Process, and CRiteria Importance Through Intercriteria Correlation to increase this model's power. This study can offer decision-makers insight to understand cause-effect relationships and select suitable sites for other research fields.

Abstract. Rahmawaty,  Frastika S, Marpaung RME,  Batubara R,  Rauf A. 2019. Short Communication: Use of Geographic Information System for mapping of Aquilaria malaccensis land suitability in North Sumatra, Indonesia. Biodiversitas 20: 2561-2568.  The Geographic Information System (GIS) can be applicated in the field of forestry and agriculture, such as for mapping as part of land evaluation. The land suitability of Aquilaria malaccensis in the agroforestry land of North Sumatra Province is important.  Commonly, A. malaccensis were planted by the community in Langkat and Deli Serdang District. This study aimed to map the land suitability for A. malaccensis in Telaga Village, Sei Bingai Sub District, Langkat District, Peria-ria Village and Sari Laba Jahe Village, Biru-biru Sub District, Deli Serdang District. A survey method was used to collect soil samples in the field. Land suitability classification (LSC) for A. malaccensis was evaluated based on the matching method.  The results showed that the actual land suitability classes for A. malaccensis in Telaga Village were moderately suitable (S2) and marginally suitable (S3). The actual land suitability classes for A. malaccensis in Peria-ria Village and Sari Laba Jahe Village were moderately suitable (S2), marginally suitable (S3) and not suitable (N). There were several limiting factors in land suitability evaluation in the area, namely: nutrient retention (nr), erosion hazard (eh), and root zone medium (rc).

Abstrak. Ketersediaan kedelai sangat penting sebagai bahan pangan dan non pangan di Indonesia, sehingga menyebabkan kebutuhan akan kedelai semakin meningkat. Namun produksi kedelai nasional tidak mampu memenuhi kebutuhan kedelai itu sendiri. Akibatnya pemerintah mulai mencari solusi untuk menanggulangi hal tersebut, salah satunya yaitu pengembangan lahan alternatif. Pengembangan lahan alternatif dapat diwujudkan melalui kesesuian lahan. Penelitian klasifikasi kesesuaian lahan ini bertujuan untuk mengetahui karakteristik dan mengklasifikasikan kesesuaian lahan tanaman kedelai di Kabupaten Aceh Tengah menggunakan Sistem Informasi Geografis (SIG). Metode pengumpulan data yang digunakan adalah dokumentasi, observasi dan uji laboratorium. Analisis kesesuaian lahan pada penelitian ini menggunakan metode overlay dan metode matching. Metode overlay yaitu penanganan data secara digital dengan menggabungan beberapa peta seperti peta penggunaan lahan, peta kemiringan lereng dan peta jenis tanah. Dari hasil overlay diperoleh 13 (tiga belas) Satuan Peta Lahan (SPL) dengan nilai karakteristik yang berbeda setiap satuan lahan. Sedangkan Metode matching digunakan untuk membandingkan karakteristik lahan SPL dengan kriteria kelas kesesuaian lahan tanaman kedelai. Hasil matching menunjukkan bahwa Kabupaten Aceh Tengah tergolong dalam kelas kesesuaian lahan S3 (Sesuai Marginal) dengan luas total 182,78 ha atau 61,78%, dan kelas kesesuaian lahan N (tidak sesuai) dengan luas total 89,29 ha atau 32,82%. Classification of Soybean Land Suitability at Central Aceh Regency Based on Geographic Information System (GIS)Abstract. Soybean availability is very important as food and non-food ingredients in Indonesia, thus causing the needs of soybeans to grow more and more. But the production of national soybeans was unable to fulfil the needs of soybeans itself. As a result, the government began searching for solutions to cope with such thing, one of them is alternative land development. Alternative land development can be realized through land suitability. The aims of this land suitability classification research were to know the characteristics and classify the soybean land suitability at Central Aceh Regency using Geographic Information System (GIS). The methods of data collection that used were documentation, observation, and laboratory tests. Analysis land suitability in this research using overlay and matching method. Overlay method is digital data processes by combining some maps such as land use map, land slope map, and land type map. From the overlay results obtained 13 (thirteen) Land Map Unit (LMU) with different characteristic values for each land unit. While the matching method is used to compare the characteristics of land LMU with the criteria of soybean land suitability class. The matching results showed that Central Aceh Regency is classified as the land suitability class S3 (marginally suitable) for planting soybean with total area of 182.78 ha or 61.78%, and land suitability class N (not suitable) with a total area of 89.29 ha or 32, 82%.
