Abstract


Air limbah yang dihasilkan dari kegiatan peternakan sapi perah dengan diversivikasi industri tahu di Dusun Klagen, Krian, Kabupaten Sidoarjo memiliki karakteristik yang melebihi baku mutu. Kualitas air limbah kegiatan peternakan sapi diketahui mencapai 1.605,24 mgBOD/L, 4.134,35 mgCOD/L, dan TSS sebesar 1.170 mg/L. Kualitas air limbah untuk kegiatan industri tahu diketahui sebesar 2.387,06 mg/L untuk BOD5 dan COD sebesar 4.204,2 mg/L, serta TSS sebesar 240 mg/L. Melihat karakteristik tersebut diperlukan instalasi pengolahan air limbah (IPAL) agar air limbah yang dibuang ke badan air memenuhi baku mutu.

Perencanaan didasarkan pada karakteristik air limbah yang diperoleh dari hasil uji laboratorium dan kondisi eksisting lokasi studi. Alternatif pengolahan yang direncanakan adalah pengolahan dengan teknologi upflow anaerobic sludge blanket (UASB) dan kombinasi anaerobic aerobic filter. IPAL yang direncanakan membutuhkan luas lahan sebesar 297 m2. Luas lahan tersebut juga meliputi bak ekualisasi sebagai penunjang pengolahan upflow anaerobic sludge blanket (UASB). Biaya yang dibutuhkan untuk membangun instalasi pengolahan air limbah sesuai perencanaan sebesar Rp 1.663.183.000.
