Analisis Indeks Kekeringan Lahan Gambut Di Kabupaten Siak Menggunakan Google Earth Engine (Gee)

ABSTRACT
Drought is a condition in which rainfall falls below normal for a certain period
and becomes a major threat to the sustainability of peatlands, as it can increase
the risk of forest fires. This study analyzes the drought index in the peatlands of
Siak Regency using the Standardized Precipitation Index (SPI) method based on
CHIRPS satellite data on the Google Earth Engine (GEE) platform, and evaluates
the relationship between SPI values and Groundwater Table Depth (TMAT). The
CHIRPS rainfall dataset used to calculate SPI spans the period from 1993 to
2024. SPI values were then compared with groundwater table depth at three
locations from 2019 to 2024 to assess the relationship between the two variables.
The results indicate spatial and temporal connections within the study area, with
several drought periods occurring simultaneously. The most significant drought
event occurred in 2019, with peak intensity in August, affecting the entire study
region. Regression analysis between SPI and groundwater table depth revealed a
positive relationship, indicating that when rainfall decreases or SPI values are
negative, the groundwater table tends to decline. However, the correlation was
relatively weak, likely influenced by other factors such as peat soil
characteristics, evapotranspiration, drainage, human activities, and others.
Nevertheless, the relationship between these two variables can serve as a
preliminary step in utilizing SPI as an important indicator for monitoring
peatland drought and supporting sustainable peatland management in Siak
Regency.
