To help mushroom industry’s waste management practices, an alternative method was developed. The main goal of this work was to pinpoint the critical parameters affecting the growth of high phosphorus (P) content in biofertilizer using mushroom waste. The parameters studied were drying temperature (60°C, 70°C, 80°C, 90°C and 100°C) and mushroom waste (MW) content (50%, 60%, 70%, 80% and 90%). The reaction time for Bokashi fermentation was 10 days, where the size of mushroom waste was cut to 1 cm and agitation was applied to the sample twice a day until the last day of fermentation process. The factors that have biggest effects on Phosphorus (P) were examined using an optimization approach by Central Composite Design (CCD) using Design Expert Software Version 7. An HACH Spectrophotometer was used to measure the amounts of Phosphorus (P) in concentration unit (mg/L). The results showed that both drying temperature and mushroom waste content are the most important factors in determining high Phosphorus (P) content. Based on the results obtained from Design Expert Software V7, the optimum conditions in producing high phosphorus biofertilizer are at 70°C drying temperature and 80% mushroom waste content with highest recorded P value at 7725.33 mg/L. Keywords: Biofertilizer; Phosphorus; Optimization analysis; Bokashi fermentation | |
