Abstract
Data of this study was obtained from direct measurement using an integrated observation system namely SEnsory data transmission Service Assisted by Midori Engineering laboratory (SESAME). The SESAME directly measures and records groundwater levels, soil moisture, skin temperature, and rainfall in peatland areas. There are two SESAME stations was used in this study, that are located in the Peatland Hydrological Unit (PHU) Lumpur River 1 and PHU Lumpur River 2. This study aims to find a correlation between Rainfall and Soil Moisture on peatlands in South Sumatra represented by the two PHUs. The results of statistical analysis show that rainfall has a significant linear correlation with soil moisture. The correlation coefficients obtained at PHU Lumpur River I and PHU Lumpur River II were 0.78, 0.64 respectively. Furthermore, the result of the empirical equation can be used to obtain the value of soil moisture based on the value of rainfall at this research location if one day soil moisture sensors are damaged.
