Abstract

Rubber commodities in East Kalimantan have a significant growth area. From 2008 to 2017, the rubber plantation area’s growth averaged 3.79%, with rubber production growth up to 4.88% per year. In addition to producing rubber latex, which is the main product of rubber trees, it also produced many rubber shells. With the vast achievement of rubber plantation area in East Kalimantan, the rubber shells production will increase as well so that it has the potential to become untapped waste. The test results of the chemical content of rubber shells taken from smallholder plantations in the Marang Kayu area contain high halo cellulose and alpha-cellulose levels, about 76.7% and 44.267 so that it has the potential to be processed into liquid smoke. Research has been carried out on rubber shell liquid smokes manufacture using a pyrolysis process with various temperatures of 250-300oC, 300-350oC, 350-400oC and 400-425oC. The highest liquid smoke rendement is at pyrolysis temperatures of 300-350oC, maximum decomposition process of cellulose and lignin content happened from rubber shells. The highest acid content test on liquid smoke by titrimetric was shown at the pyrolysis temperature of 350-400oC, about 12%. Identification of the chemical content of liquid smoke using GCMS was obtained with the highest content in acid products and their derivatives, with an area of acetic acid of 54.43%. Liquid smoke of rubber shells formed has a pH of 3.4 so that it can be used as a latex coagulant and produce rubber quality of SIR 5 sheets according to SNI 1903-2011.
