Palangka Raya is the capital city of Central Kalimantan Province which was planned as a candidate for the capital city of the Republic of Indonesia by the National Development Planning Agency. Urban development plans and increasing population growth require optimal solid waste services. This study aims to predict the solid waste generation of Palangka Raya city in the next 20 years to plan waste infrastructure needs, to determine the location of temporary shelters and effective routes for collection truck. Population projection and solid waste generation are calculated using arithmetic, geometric, and exponential models. The projection model is selected based on the determination coefficient value closest to 1. The spatial weighting method is employed to determine the location of the temporary shelter and the garbage collection truck routes. Based on the chosen model, the population of the Palangka Raya city is projected to 460,282 people by 2039 with the waste generation volume to 1,140 m3/day. More detailed regional waste generation projection data is essential for the government to calculate the number of required temporary shelters, to determine its location, to determine the time to collect waste, and to determine effective collection truck routes. Hence, the performance of solid waste services can be improved. Increasing the volume of waste that can be handled will reduce the volume of unmanaged waste that has the potential to deteriorate the environment.
