Abstract:
Infiltration can affects hydrological cycle in area. The infiltration process is also required by vegetation. Infiltration can occur in various land covers. This study has a purpose was to determine the infiltration rate on various land covers, determine the capacity and volume of infiltration on various land covers in the Special Purpose Forest Area (SPFA) Mandiangin, South Kalimantan. Land cover in this study was grouped into 4 namely reeds, shrubs, rubber and secondary forest. Primary data collection was carried out directly in the field using an infiltrometer to further analyze the infiltration rate, capacity and volume of infiltration. Each land cover was replicated 3 times so that the number of samples was 12 samples. The largest infiltration rate was found in the bushland cover of 2.57 mm/hour and the smallest was at the alang-alang area of 0.3 mm/hour. The largest infiltration capacity and volume was found in bushland cover with an infiltration capacity of 7.03 mm/hour and an infiltration volume of 3.15 mm3. While the smallest occurred in Imperata land cover with an infiltration capacity of 0.27 mm/hour and an infiltration volume of 0.14 mm3.
