Evaluation of Tidal Swampland Suitability Based on GIS Spatial Model on Barambai Reclamation Unit, South Kalimantan

Abstract

Barambai reclamation unit in Barito Kuala regency, South Kalimantan, has great potential for tidal swampland agricultural development. Therefore, agricultural land suitability information is required. Evaluation of Barambai agricultural land suitability is conducted using Quantum GIS (Geographic Information System) software on land unit categories data (pyrites, cation exchange capacity, ash content value, salinity, hydrotopographic zone, and drainability). Identification and analysis results indicated that soil fertility is low to moderate, the pH of the soil is acid to very acid, and relatively high pyrite hazards. Agricultural land suitability in Barambai tidal swampland reclamation unit is most suitable for paddy plant (S1 and S2 criteria).
