Abstract

Banua Botanical Gardens is an urban forest located within the office complex of South Kalimantan Province. The Banua Botanical Gardens area occupies an area of approximately 100 hectares, right across from the office of the governor of South Kalimantan Province. The Banua Botanical Gardens area is an open expanse with a relatively flat land surface, red-yellow podsolid soil type, hard texture, and gravel. Before being made a botanical garden, this area was a former traditional diamond mining area that the community had abandoned several decades ago. The condition is mostly marginal land which is characterized by a very thin topsoil. The aims of this study are to analyze the land in the Banua Botanical Gardens based on data from the interpretation of Sentinel 2 Imagery in 2021 and Drone coverage on October 14, 2021; 2) to recommend the development of vegetation in the Banua Botanical Gardens based on the results of the land suitability analysis. The approach used in this research is quantitative methods and descriptive analysis. The object of this research is the soil sample at 6 (six) points according to the density class and the type of land cover along with its spatial parameters, namely area and length, tree inventory data, and market prices. The results showed that the land suitability assessment in dense land class was S1 for sengon plants, S2 rc nr for acacia plants, N nr for trembesi plants, and S2 rc nr for rubber plants. The results of land suitability assessment on medium land class S2 nr for sengon plants, S2 rc nr for acacia plants, N nr for trembesi plants, and S3 nr for rubber plants. The results of the land suitability assessment on rare land classes were S2 nr for sengon plants, S2 rc nr for acacia plants, N nr for trembesi plants, and S3 nr for rubber plants. Recommendations for the development of vegetation in the Banua Botanical Gardens are carried out with improvements to the characteristics of the land.
