Abstract

Accurate and comprehensive land condition mapping is crucial for infrastructure development planning, particularly for data center construction in Nongsa Special Economic Zone (SEZ). This research integrates terrestrial survey, photogrammetry, and geographic information system (GIS) data to produce optimal land condition maps. The methodology involves field data collection through terrestrial measurements, aerial photography using photogrammetry, and data processing/analysis using GIS tools. This integrated approach enables the creation of comprehensive land condition maps, incorporating topography, land use, and other supporting parameters. The results demonstrate improved mapping accuracy and detailed spatial information, supporting informed location decisions. Eleven thematic maps were created, including topography, longitudinal and transverse profiles, composite volume, DSM/DTM contours, land cover, soil type, slope, water density, and flood hazard maps. Flood hazard analysis reveals that Nongsa has low (1.13 km²), moderate (61.16 km²), high (34.32 km²), and very high (0.0078 km²) flood risk areas. The majority of Nongsa (61.16 km²) falls within the moderate flood risk category. This research identifies that a significant portion of Nongsa, specifically 61.16 km², is categorized as having a moderate flood risk, highlighting the need for targeted infrastructure planning and risk mitigation strategies in the development of data centers within the SEZ. The results of this study also provide important insights into the impact of land use changes on the local ecosystem, making them valuable for planning more environmentally friendly and sustainable development.

Abstract

Papaya (Carica papaya L.) is a high-value horticultural crop that can be cultivated year-round and helps improve farmers’ incomes. However, successful papaya cultivation depends heavily on environmental conditions, making land suitability assessment a critical step for sustainable development. This study examined the limiting factors influencing the suitability of agricultural land for papaya cultivation on Galang Island using a Geographic Information System (GIS) approach. The study used matching and scoring methods to evaluate land characteristics against papaya growth requirements. The assessment was conducted for each land unit to identify actual and potential land suitability classes based on key environmental parameters. The findings show that land suitability on Galang Island is divided into two categories: actual and potential. Under current conditions, land units 1, 2, and 3 fall into the S3 (marginally suitable) class, with water availability (wa) identified as the primary limiting factor, resulting in an S3wa classification. Improvement measures were proposed to enhance land suitability by increasing the suitability class by one level. The implementation of irrigation systems, improved soil management, and appropriate fertilization is expected to upgrade land units 1, 2, and 3 to the S2 (moderately suitable) class. After improvement, land suitability is classified as S2wa, tc, with water availability and temperature remaining as limiting factors. Some parameters cannot be improved due to inherent natural conditions. Overall, Galang Island demonstrates significant potential for sustainable papaya cultivation.
