The potential of palm oil shell waste reaches 37.6% (14.9 million tons / year) with a total energy potential of 54.8 Giga Joules / year. This study aims to determine optimization the temperature and time of pyrolysis of white charcoal production from palm oil shell waste and acacia bark waste with surface response method (RSM). The research was conducted in two stages. The first stage is the production of oil palm shell briquettes. Palm shells are reduced in size to 60 mesh mixed with 7% tar, then pressured (200 kg / cm2). The next step is pyrolysis at 600 ° C, 700 ° C, 800 ° C for 2, 4 and 6 hours. White charcoal briquette products are analyzed by calculating fixed carbon content, water content, volatile matter content, ash content, and calorific value. Then an optimization is carried out with the surface response method (RSM) in order to obtain optimal conditions for the production of white charcoal briquettes from palm oil shell waste and acacia bark. The results showed that the optimal production of the pyrolysis conditions of oil palm shell briquettes was at 780.8 ° C for 5.25 hours. White charcoal briquettes that are produced under optimal conditions have characteristics of 81.57% fixed carbon content, 2.78% volatile matter content, 1.7% moisture content, 13.73% ash content, and calories value 7190.99 KCal / kg.
