Breakdown of fallen leaves takes a long time, which can be an issue when people often burn leaves in small towns, and even for farmers who need to quickly add more nutrients to soil. This study aims to evaluate the efficacy of the CelluSynth mulch machine, partnered with Bacillus subtilis and cellulase, in speeding up leaf biodegradation and enhancing soil fertility. ‎The experiment was conducted in the form of a static group comparison design. One set of 200 grams of leaves was processed in the CelluSynth, while the other set of 200 grams was placed in a traditional wire mesh setup where leaves were soaked up in water. Both treatments were monitored weekly for six weeks to measure the decomposition percentage.‎ It was determined that CelluSynth-treated mulch was able to accelerate leaf decomposition to 97-98%, while natural decomposition only ever reached 60%. The CelluSynth mulch not only decomposed and produced nutrient-rich soil but also improved the growth of Sunn Hemp, as heavily mulched plots reached 73 cm, having 146 leaves and 312 grams of dry biomass, while the plots with traditional mulch only reached 60 cm, 120 leaves, and 248 grams of dry biomass. A two-way ANOVA indicated that both the use of CelluSynth mulch and the duration of mulching significantly improved growth rate and net primary productivity (p < 0.01). Its advisable to perform further refinement of the machine to conduct pilot tests under various organic waste conditions, and to better tailor the ratios of decomposed organic plant waste.
