The results of previous studies have obtained several bacteria that are tolerant of plastic waste. However, its ability has not been tested as biodegradation of plastic and biological fertilizers. Therefore this research is intended to test the potential ability of these bacteria as biodegradation of plastic waste and as biological fertilizer by using Gas Chromatography-Mass Spectrophotometry (GC-MS). GC-MS analysis results on SP6 isolates as plastic-tolerant bacterial models, have obtained 5 specific secondary metabolites which act as biodegradation of plastic with the composition: Malic acid (?4?6?5) 1.85%, Xanthine (?5?4?4?2) 1.08%, Myo inositol ( ?6?12?6) 1.32%, γ Glutamyl alanine (?8?14?2?5) 0.85% and Ribitol 5 phosphate (?5?13?8?) 1.30%. In addition, the isolate was also able to synthesize several phytohormones with the composition: α Aminobutyric acid3 (C4H9NO2) 1.20%, Indoleacetic acid (C10H9NO2) 1.85%, Kinetin (C10H9N5O) 1.19%, Kinetin glucoside (C16H19N5O7) 1,19 % and Benzyladenine 9 glucoside N6 (C18H21N5O5) 1.31%, thus the bacterium has a double potential, besides being able to degrade plastic, it also has the potential as a biofertilizer.
