Abstract

Negara-negara berkembang termasuk Indonesia, pencemaran domestik merupakan jumlah pencemar terbesar (85%) yang masuk ke sungai. Sebagian besar masyarakat masih membuang air limbah domestik dari kegiatan mandi, cuci, dan kakus (grey water) begitu saja ke dalam saluran drainase yang seharusnya untuk air hujan. Perlu adanya instalansi pengolahan limbah MCK secara mandiri. Penulis menerapkan pengolahan limbah MCK berbasis biofilm mikoalga pada penelitian ini. Tujuan penelitian adalah mengetahui waktu detensi pengolahan terbaik, efisiensi penurunan parameter BOD, TSS, nitrat, dan amonia serta mengetahui baku mutu air hasil pengolahan. Pada penelitian ini menggunakan rancangan instalasi pengolahan limbah MCK dengan mendesain reaktor pengolahan yang terdiri dari beberapa proses seperti sedimentasi, biofilm, mikroalga, filtrasi, dan reservoir dengan volume air limbah sebesar 400 L. Berdasarkan hasil penelitian, waktu detensi pengolahan limbah MCK terbaik selama 24 jam. Karakteristik air limbah MCK setelah dilakukan pengolahan diantaranya pH sebesar 7, BOD sebesar 10,58 mg/L, TSS sebesar 8,5 mg/L, nitrat sebesar 1,283 mg/L, dan amonia sebesar 0,029 mg/L. Penentuan baku mutu air pada hasil pengolahan air mengacu pada PP R.I. No. 82 Tahun 2001 Tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air bahwa parameter pH. TSS, nitrat, dan amonia masuk dalam baku mutu kelas II sedangkan parameter BOD belum termasuk. Penulis mengarahkan air hasil olahan diperuntukan untuk kelas III.

English Abstract

Indonesia is one of on the world where domestic pollution is the biggest polluters (85%) that goes into a river. The majority of citizent still dispose of domestic waste water from daily activities (grey water) casually into the drainage channels which it intended for rainfall water to rain. Actually we need to build the wastewater treatment plant facility independently. The author applies the wastewater treatment plant based on this combine with biofilm mikroalga technology in this research. The purpose of the study is to know the best of detention time processing, the efficiency from decreasing the parameters of BOD, TSS, nitrate, and ammonia and knowing the results raw water quality processing. In this research design of waste water treatment plant installation using many design with reactor processing that consists of several processes such as sedimentation, filtration, biofilm, mikroalga, and reservoir with a volume of wastewater of 400 l. Based on research results, the best of detention time sewage treatment for 24 hours. The characteristics of the wastewater after processing is pH 7, BOD 10.58 mg/L, TSS 8.5 mg/L, nitrate 1.283 mg/L, and ammonia 0.029 mg/L. Regulation of Indonesian waste water quality determineted by referring on Government Regulations Republic of indonesia Number 82 2001 About Water Treatment and Water Pollution Control from that regulation the parameters of the pH. TSS, nitrate, and ammonia in this research entered quality class II whereas the parameters of BOD is not included. The writer directs the result of water treatment intended for class III.
