gathering of people in the city of Yogyakarta, Indonesia, at a location with coordinates -7.783 latitude and 110.367 longitude. It appears to be a demonstration or protest. The group is sitting on a paved area in front of a truck with a large speaker system in the back. There are several people standing behind the truck, including a man in a red shirt standing on a platform holding a microphone. The people on the ground are mostly wearing casual clothing and holding signs or flags. There are banners on the ground, including one that reads "Federasi Serikat Serikat Indonesia (FSSI)." There are also numerous flags, including blue, red, and white flags, which are potentially symbols representing the people's cause. The image is captured under a partly cloudy sky with a tall, white, and golden-topped monument in the background. The environment suggests a public area in a city with buildings and streets in the background.
