The use of lightweight concrete materials in Indonesia, especially in the Merauke Regency area can be an alternative amid the rapid development of the housing sector. In this experimental study, the author took the initiative to replace coarse aggregate with wood charcoal as light coarse aggregate. The purpose of this study was to determine the value of compressive strength and to determine whether the wood charcoal material met the standard of lightweight concrete coarse aggregate. Planning the proportion of lightweight concrete mixture in this study using a volume ratio between cement, sand and wood charcoal of 1: 2, 1: 2: 2.5 and 1: 2: 5 with variations of test days at 3, 7, 14, 21 and 28 day. From the results of the compressive strength test of lightweight concrete, the use of wood charcoal aggregate as coarse aggregate in concrete causes the value of the compressive strength of concrete to decrease.
