Mesoscale Convective Complex (MCC) is a mesoscale cloud convective system characterized by large, long-lived and quasi-circular pattern. The existence of MCC may trigger extreme weather events such as heavy rains which cause floods and landslides around the center of interest area. This paper aims to identify the presence of a storm cloud system which is observed as the MCC. For that purpose, this study used Himawari-8 satellite infrared channel data. Case of the study is the rain event in Bangka Belitung on 8 February 2016 which recorded 183.9 mm rainfall a day. Satellite data was processed using image processing software by applying MCC cloud system identification algorithm based on its physical characteristics, i.e. peak cloud temperature, coverage area, central point of cloud, cloud eccentricity and ellipse fitting, and lifetime of the cloud system. The final result of this study is able to yield the coordinates of latitude and longitude of MCC location, which are MCC cloud systems appeared around Bangka Belitung. This result confirmed that the occurrence of heavy rain on February 8th, 2016 in Bangka Belitung was caused by the presence of MCC around the interest area.
