In Batu Ampar, the charcoal industry, West Kalimantan, used Rhizophora sp. mangrove to produce liquid acid with mangrove stem bark waste as a side product. Pyrolysis of liquid smoke of mangrove stem bark waste at a temperature of 4000C for 6 hours resulted in a yield of 33.97% with pH, specific gravity, and color were 2.8, 1.004, and brown, respectively. Analysis of GC-MS showed that liquid smoke without distillation has 16 chemical compounds where the main components were acetone (12.32%), acetic acid (11.62%), 2-furancarboxaldehyde (26.72%), 5-methyl furfural (13.87%) and phenol, 2-methoxy (13.31%). Furthermore, this liquid smoke is distilled at 1000C to produces residual liquid smoke and distillate liquid smoke. The residual liquid smoke resulted in a yield of 95.8% with characteristics of pH, specific gravity, and color were the lowest 2.73, 1.004, and dark brown, respectively. The liquid smoke residue contained 12 chemical compounds where the main components were butanal, 3-hydroxy- (17.46%), acetone (17.15%), acetic acid (32.27 %), and 2-furancarboxaldehyde (13.28%). Distillate liquid smoke resulted in a yield of 4.2% with pH, specific gravity, and color characteristics, which were 2.8, 1.001, and yellow, respectively. This liquid smoke contained nine chemical compounds, with the main components were ethyl ester (26.69%) and ethylene glycol (64.70%). Based on the GC-MS data, the liquid smoke from mangrove leather waste did not contain poly-aromatic hydrocarbon (PAH) or benzopyrene compounds.
