HASIL PLAGIASI ANALISIS INFILTRASI DI HUTAN KOTA PERKANTORAN GUBERNUR PROVINSI KALIMANTAN SELATAN

Abstract

Urban forest is an important factor affecting the sustainability of ecological and social conditions in the urban environment. One of the urban forest in Banjarbaru is Tropical Rain Forest Miniature. The urban forest is located in the South Kalimantan provincial government office area in Banjarbaru.

At different land uses will be found the type of vegetation and land management of different levels. Where these two things will also cause a different rate of infiltration. This research uses the Horton Model which aims to analyze the nature of the soil, determine the infiltration rate, infiltration capacity and infiltration volume in urban forest governor office of South Kalimantan province. Infiltration rate measurements using an infiltrometer conducted on 4 planting blocks in miniature tropical rainforest. The results showed that: 1) Texture of sandy clay loam and sandy loam; 2) The largest infiltration rate is in Block 4 with a value of 87.33 mm / hour and the lowest infiltration rate in Block 3 with a value of 29.00 mm / hour; 3) The largest infiltration capacity and infiltration volume are in Block 4, which is 46.23 mm / hour and 50.23 mm3, while the lowest infiltration capacity and infiltration volume is in Block 3, which is 12.82 mm / hour and 9.48 mm3.
