Abstract

− Pengolahan air limbah domestik dengan proses biologi menggunakan jenis bakteri probiotik PMPF berdampak positif terhadap lingkuan air maupun darat. percobaan dilakukan dengan tujuan agar air limbah dapat dimanfaatkan kembali menjadi air baku maupun air yang produktif. Parameter pencemar limbah berupa Chemical Oxygen Deman (COD), Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), dan pH, adalah beberapa parameter kimia yang dapat digunakan untuk mengidentifikasi air limbah tersebut aman digunakan untuk keperluan sehari-hari yang lebih produktif. Media yang digunakan adalah bakteri PMPF dengan variasi komposisi dan waktu tinggal. Kombinasi percobaan tersebut dibedakan menjadi tiga tipe yaitu tipe 1, tipe 2, dan tipe 3 dengan waktu tinggal  adalah 5 jam; 8 jam; 10 jam.. Tipe percobaan yang memiliki efisiensi paling baik adalah percobaan tipe 1 yang menunjukkan penurunan COD pada 5 jam, 8 jam, dan 10 jam berturut-turut sebesar 62.61%, 69.75%; dan 70.68%, untuk BOD menunjukkan efiseiensi 74,84%, 82,58%; dan 83,87%, untuk dan TSS 74,84%, 82,58% dan 83,87%. Dengan adanya pengolahan air limbah dengan PMPF diharapkan air limbah dapat dimanfaatkan sebagai faktor produksi guna mewujudkan proses pengolahan air limbah domestik yang ramah lingkungan..

Abstract

The existence of quite a lot of tofu industry is actually inseparable from the risk of environmental pollution due to waste being dumped directly into waterways. Tofu wastewater needs to be treated first to meet the set quality standards before being discharged into the environment because it contains organic pollutants that can damage water. In this study, researchers used commercial probiotic products to reduce BOD and COD levels and increase DO levels in tofu wastewater. Data analysis in this study is statistical analysis by observing in the laboratory. The presentation of the data used is statistical data with a graphical method that can show the results of differences in wastewater before and after being given probiotics. The results showed that changes occurred when commercial probiotics were added to tofu wastewater. The results of the DO test showed that the ALT mixed with probiotics increased to 1.03 mg/lt at a ratio of 1:3 in 8 hours. The same results were also obtained from ALT-N which increased by 1.25 mg/lt in a ratio of 1:3 at 8 hours. In the COD and BOD tests, the levels dropped to 83.42 mg/lt and 179.47 mg/lt for ALT-N. The results showed that commercial probiotics added to tofu wastewater were able to reduce BOD and COD levels and increase DO levels.
