  • Waste is still one of the problems that exist in the surrounding environment, each year the population increases and is directly proportional to what is consumed. Waste can be processed into compost, but in the making there are several problems. One solution that can be used is by using bacteria. Therefore this study was made to test the ability of bacteria in various TPAS to break down various organic materials such as cellulose, lignin and chitosan and their potential as biofertilizers. The research was conducted at UMM Biotechnology Laboratory and UMM Agrotechnology, on February 15 - October 10. The implementation stage is to isolate TPAS soil, then the bacteria found are isolated and tested using carbon sources of cellulose, lignin and chitosan to test the potential of isolates as biodecomposers and GCMS testing with the addition of tryptophan to test the potential of isolates as biofertilizers. The study used a factorial CRD design study with the first bacterial factor and the second factor the level of carbon source administration. The carbon source level is five, namely 0%, 25%, 50%, 75%, and 100%, replications are carried out five times and the data obtained is analyzed using variance analysis (ANOVA) and tested by comparison using the Tukey Distance Test (Honest Real Difference) at the level of α5%. The results showed that the isolates tested had different characteristics, and had the potential to be used as biodecomposers, this was indicated by the ability of bacteria to survive under conditions of giving carbon sources with different levels. ESP1 isolate is the isolate with the highest growth ability during growth testing, and ET1 isolates are the lowest growth isolates. Isolate also has the potential to be used as a bofertilizer which is indicated by the presence of fitorhomon produced through the GCMS test.
