This study aims to determine the potency of the spread of smoke due to forest and land fires using the latest geostationary orbit satellites, the Himawari 8 Satellite operated by Japan Meteorological Agency (JMA), which observes the Asia-Pacific region and to know the best combination of channels for smoke detection. The Himawari-8 satellite which has been since 2015 as the successor to the MTSAT satellite has 16 channels and produces data every 10 minutes. Smoke detection was done by combining several channels, including channels 3, 4, 5, 6, 7, and 13. Adjustment of image mixture was carried out using the RGB (Red, Green, Blue) technique. Validation of Himawari-8's RGB smoke products was carried out at certain times during August 23-28, 2016 adjusting the hotspot detection time of MODIS Aqua-Terra satellite which indicates the point of fire. Hotspot data from the Aqua-Terra MODIS satellite were overlayed on Himawari-8's RGB smoke products. Analysis and verification of smoke distribution patterns were carried out using ECMWF reanalysis wind speed and direction data which was previously verified by the observation of wind speed and direction data from BMKG in the form of windrose. The presence or the absence of haze events in the study area were ensured by utilizing the horizontal visibility data and the related significant weather conditions taken from BMKG. Himawari-8 satellite was able to detect smoke from forest and land fires in Riau Province with the RGB false color technique. The best channel combination in detecting smoke is channel 3 (0.64 ?m), channel 4 (0.86 ?m), and channel 6 (2.3 ?m) which is indicated by the appearance of a brownish yellow pattern. Wind is very influential in the spread of smoke due to forest and land fires because of its movement in accordance with the direction of the wind blowing at that time. Movement of smoke distribution according to the direction of wind movement up to a level of 850 mb.
