Abstract
The Positive Indian Ocean dipole (IOD+) phenomenon has resulted in minimal rainfall in South Sumatra. South Sumatra has extensive peatlands and its conditions are strongly influenced by rainfall. The lack of rainfall causes the groundwater level in peatlands to decrease so that the surface of the peatlands becomes dry and prone to fire. This research was conducted in one of the peatlands in South Sumatra by utilizing data from an integrated in situ measurement system called SESAME. The aim is to study the decrease in rainfall and groundwater level in the peatlands due to the IOD+ phenomenon in 2019. Based on the results of this study, it was found that in the dry season in 2019, rainfall was minimal, namely only 75.6 mm in August and 82 mm in September. Groundwater level also decreased significantly and even reached -1.04 m in October. The speed of decreasing groundwater level is -0.71 cm/day. The results of this study also show that the groundwater level is strongly influenced by rainfall.
