Description
Summary:Climate change has brought changes to the characteristics of the rain, wherein the rainy season duration is short; however, the dry season is getting longer. This study aims to detect the climate change presence or absence, identify the relationship of climate change to the nature of rainfall, and the relationship of climate change to rainy, humid and dry months. This research was conducted in the Mepanga Watershed, Parigi Moutong Regency, Central Sulawesi, Indonesia. The Makesens method is used for climate change detection. The rainfall characteristics use standard deviation statistical methods; furthermore, the Oldman method is used for dry, humid, and wet months. The data used is rainfall data for 30 years (1990-2019) from Kayu Agung Station. The results show that there has been a climate change in the Mepanga watershed. Marked by a Z ≠ zero value, where there is a positive trend (Z> 0) and a negative trend (Z
