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).

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.

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

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.
