Indonesia is a country that is often struck by floods and forest fires. The El-Nino and La Nina phenomena are natural factors that cause Indonesia to experience two different disasters. During El Nino, most parts of Indonesia experience minimum rainfall, resulting in drought which triggers forest and land fires. Conversely, when La Nina hit, Indonesia experienced quite extreme rainfall which causing floods. LAPAN A4 is prepared to be a part of a microsatellite consortium in Asia that will carry a thermal infrared sensor (TIS) camera designed by Hokkaido University. This TIS camera has a spec measurement range of 100 ° C to -60 ° C. So, it can be used to detect hotspots during the dry season or cloud growth during the rainy season. TIS cameras have independently conducted several tests to test the resistance of TIS cameras to the environment when stored, launched, and operated. Temperature calibration has also been carried out to get a digital value function as a temperature value. The current status of LAPAN-A4 development is being assembled and tested.
