Abstract

Indonesia is a developing country with a high population growth yearly. This has resulted in many students entering a productive age throughout Indonesia. Based on the Central Bureau of Statistics, in 2021, there were 3,115 public and private tertiary institutions with 7,665,516 active students: especially in Malang City. The high number of students in Malang City also affects the growth of the laundry business. Therefore, this study aims to create a filtration model to reduce the levels of BOD contained in laundry waste in Malang City. The method used is an experiment using ten samples of laundry waste in Malang City. Measurement of BOD levels will be carried out before and after filtration. In this study, the filtration model uses two filters with the letter L model. The statistical test used was the Wilcoxon test to see the difference before and after filtration using the filter model. Based on testing of 10 samples of laundry waste in Malang City, it showed that the BOD content of all samples exceeded the quality standard of 30 mg/l. To see the differences before and after filtration, the Wilcoxon statistical test resulted in a p-value of 0.022 with an alpha of 0.05, so there were differences in BOD levels before and after filtration. The average BOD in 10 laundry waste samples before filtration was 257,939 mg/l, and after filtration was 172,209 mg/l. Based on the results of the tests carried out, it was found that there were differences in BOD levels before and after filtration using the filter model that was made. In addition, from an average of 10 laundries, there was also a decrease of 83 mg/l. Even though the BOD level after filtration was still above the quality standard, the reduction was quite significant.
