This research was conducted for six months from June to December 2016. This study analyzed the market and marketing of rice husk waste and corn cobs into charcoal briquettes and analyzed the feasibility of investment in the construction of charcoal briquette installations in Tanah Jawa District, Simalungun Regency. The samples in this study were entrepreneurs of rice refineries and corn refineries spread in Tanah Jawa District, Simalungun Regency. The sampling method used is the saturated sample method, which is a deliberate sampling process wherein because the population is small, all populations are sampled.
