Peatlands play a crucial role in maintaining hydrological balance, storing carbon, and preventing both flooding and drought. However, changes in land use and improper water management can disrupt these ecological functions. This study was conducted to evaluate the water balance conditions in the peatland area of the Arboretum, Faculty of Agriculture, Sriwijaya University, with the specific aim of determining whether the area experiences water surplus or deficit during a one-year observation period. The results of this study are expected to serve as a foundation for sustainable water management in the peatland area of Sriwijaya University. The method used in this research was a field survey with a scale of 1:8000, covering an area of 20 hectares. The collected data included rainfall, actual evapotranspiration (ETa), land elevation, and climate information from the Meteorological, Climatological, and Geophysical Agency (BMKG). Water balance analysis was carried out using the Tampubolon (2020) method, calculating surplus and deficit values based on the comparison between rainfall, evapotranspiration, and changes in groundwater storage. The measurement results were presented in tables, graphs, and topographic maps to illustrate the hydrological conditions of the study area. The study revealed that the peatland in the Sriwijaya University Arboretum experiences two main phases: water surplus and deficit periods. The surplus period occurs from November to April, peaking in December and March (at +200 mm and +190 mm, respectively). Conversely, the deficit period takes place from May to October, with the highest deficit recorded in August (–110 mm). This pattern reflects the characteristics of a tropical monsoonal climate, where the rainy season generates water surplus, while the dry season causes drought and a decline in groundwater levels. In general, the flat topography and natural vegetation of the study area help maintain water storage during the rainy season but increase the risk of drying and peat fires during the dry season. This condition highlights the importance of ecosystem-based water management to sustain the hydrological function of peatlands. The study concludes that water availability in peat areas is strongly influenced by rainfall, evapotranspiration, and topographic conditions. Therefore, continuous hydrological monitoring and integrated water management—such as canal blocking and natural vegetation restoration—are necessary to maintain water balance and prevent peatland degradation.
