Abstract
Abstract: Utilization Spuit Used As Media biofilters on Reducing levels of BOD and COD Wastewater Laundry . The aim of this study was to test the ability of the media syringe biofiltration method used in lowering levels of BOD and COD in waste water laundry Hospital Dr. Soedarso Pontianak. This research is a quasi-experimental research design with one group pretest-posttest. Laboratory results mean BOD levels before processing is 103.63 mg/L and the average after processing into 46.41 mg/ L, with a value of 55.21 % effectiveness. While the average COD level before processing is 413.70 mg / L and the average after processing into a 195.88 mg/L with a value of 45.92% effectiveness. Expected to other researchers to control the pH and blowers before treatment and during treatment, as it will affect the final result.
Abstrak : Pemanfaatan Spuit Bekas Sebagai Media Biofiltrasi Dalam Menurunkan Kadar BOD dan COD Air Limbah Laundry . Tujuan dari penelitian ini untuk menguji kemampuan metode biofiltrasi dengan media spuit bekas pakai dalam menurunkan kadar BOD dan COD pada air limbah laundry RSUD Dr. Soedarso Pontianak. Penelitian ini merupakan penelitian eksperimen semu dengan rancangan penelitian one group pre test post test. Hasil laboratorium rata-rata kadar BOD sebelum pengolahan yaitu 103.63 mg/L dan rata-rata setelah pengolahan menjadi 46.41 mg/L, dengan nilai efektivitas 55,21 %. Sedangkan rata-rata kadar COD sebelum pengolahan yaitu 413.70 mg/L dan rata-rata setelah pengolahan menjadi 195.88 mg/L dengan nilai efektivitas 45,92 %. Diharapkan kepada peneliti lain untuk mengontrol pH dan blower sebelum perlakuan dan pada saat perlakuan, jika melakukan penelitian sejenis karena akan mempengaruhi hasil akhir.
