Penelitian ini bertujuan untuk mengetahui efektivitas IPAL dengan sistem Biofilter Aerob-Anaerob dalam menurunkan kandungan 1. TSS (Total Suspendes Solid) 2. TDS (Total Disolve Solid) 3. Kekeruhan dengan pengambilan sampel sebanyak 8 kali, lalu dianalisa dengan menggunakan uji T berpasangan. Hasil menunjukan tedapat perbedaan nyata pada ketiga parameter. Berdasarkan pada hasil analisa dikatakan bahwa efektivitas TSS 60,54%, TDS 30,77% dan Kekeruhan 54,26%.
Kata kunci: Efektivitas IPAL, TSS, TDS dan Kekeruhan

The purpose of this research is to know the effectiveness of IPAL with Biofilter Aerob-Anaerob system to reduce the content TSS (Total Suspended Solid), TDS (Total Disolve Solid) and Turbidity. With taking the sample for eight times, then analysed with using couple T test. The result show that there are real differences in tertiary parameters. Based on the analysed result that the effectiveness of TSS 60,54%, TDS 30,77% and Turbidity 34,26%. Keyword: effectiveness of IPAL, TSS, TDS and Turbidity
