Analisis Konduktivitas Hidrolik Dengan Metode Constant Head Permeameter Test Pada Hutan Rawa Gambut Tropis Sebangau Provinsi Kalimantan Tengah

Abstract

Peatlands are generally located in wet and flooded swamp areas, both tidal and inland peatlands. Peat swamp forests are important ecosystems with diverse flora and fauna, and serve as carbon sinks and water reservoirs. Changes in land use can disrupt the water management system in this area. The Sebangau tropical peat swamp forest is still considered natural because its authenticity is well preserved. To maintain this condition, good water management is required, one of which is through peat soil hydraulic conductivity data. However, the availability of hydraulic conductivity data is still limited, so further research is needed. Hydraulic conductivity values were obtained by testing peat soil samples taken directly from the Sebangau Peat Forest Nature Laboratory (LAHG) at depths of 0–50 cm, 50–100 cm, and 100–150 cm vertically, as well as horizontally at depths of 25 cm, 75 cm, and 125 cm with two sampling rounds. The measurements were carried out using the constant head permeameter test method. The results showed that sample A had a KV value of 0.0916 cm/dt and a KH value of 0.0276 cm/dt, while sample B had a KV value of 0.0298 cm/dt and a KH value of 0.0426 cm/dt.
