The potential of Trichoderma spp. and Pseudomonas auregenosa as patchouli waste decomposer

Abstract

Abstract Currently, waste from patchouli distillation process is unutilized. It is known that the waste still has high nutrient content and has the potential as raw material for organic fertilizers. In this study, we investigated the potential of Trichoderma harzianum, T. asperelum, and Pseudomonas aeruginosa as biodecomposer in patchouli waste composting process. The bio decomposers were inoculated to patchouli waste to determine the effect on composting process time, maturation and compost chemical properties. T. harzianum and T. asperelum were added to the compost raw material in the form of pellet (15 g). While P. aeruginosa added suspension at 108 as much as 20 ml. The results showed that the inoculation of T. harzianum, T. asperelum and P. aeruginosa accelerated the decomposition process and improved the compost texture. Chemical properties analysis indicated that the compost produced meet Indonesia compost standarisation. This study revealed that T. harzianum, T. asperelum and P. aeruginosa are potential patchouli waste decomposers.
