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.

Lansium Domesticum

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.

Suitability Assessment

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.

The expansion of plantations of cocoa is the main component in the plantation revitalization program which is applied by the Government of Indonesia in order to optimize the potential of cocoa. This policy has not been implemented well in East Dusun District, East Barito Regency, Central Kalimantan province that just open cocoa plantations covering an area of 3 ha in the year 2016. The spatial analysis of land suitability by utilizing Geographic Information System capability that allows the expansion of plantations of cacao in this district. Spatial analysis to get the suitability of land for cocoa plantations uses overlay based on climate conditions and regulations of the Governor of Central Kalimantan. The proportion of land suitability class that is highly suitable, suitable, marginally suitable, and not suitable with each area size of 56,434.63 ha, 2,302.81 ha, not found, and 19,510.42 ha.   Keywords: Cocoa, Overlay, Land Suitability
