Abstract

Cikapundung merupakan salah satu sungai yang digunakan oleh PDAM Kota Bandung sebagai sumber air baku. Penurunan kualitas air yang terjadi di Sungai Cikapundung merupakan salah satu alasan mengapa perlu untuk mengevaluasi kinerja Instalasi Pengolahan Air Minum (IPAM) Dago Pakar . Tingginya tingkat pencemaran pada sumber air baku ini disebabkan oleh masih banyaknya warga masyarakat yang membuang sampah dan kotoran hewan ternak ke sungai juga erosi. Dengan kondisi tersebut IPAM Dago Pakar mencoba untuk mengolah air baku ini agar dapat menghasilkan air bersih yang layak dikonsumsi oleh masyarakat dan sesuai dengan standar yang berlaku yaitu Peraturan Menteri 492/MENKES/PER/IV/2010. Metoda penelitian dilakukan dengan cara menghitung rata-rata debit dari BBWS dan IPAM Dago Pakar, mengevaluasi kinerja IPAM berdasarkan evaluasi pada air hasil olahan yang dihasilkan serta evaluasi terhadap kriteria desain bangunan unit pengolahan. Berdasarkan observasi dan studi pustaka, dapat disimpulkan antara lain IPAM Dago Pakar memiliki satu (1) seri pengolahan air lengkap, yang terdiri dari intake, pra-sedimentasi, koagulasi, flokulasi, sedimentasi, filtrasi, desinfeksidan reservoir, (2) total kapasitas IPAM Dago Pakar adalah sebesar 600 L/detik, (3) pada musim penghujan, proses backwash bisa dilakukan hingga 3-5× 1 hari/unit untuk itu disarankan pihak PDAM membangun sebuah bak penampungan air hasil backwash agar dapat dipompakan kembali ke unit koagulasi untuk diolah kembali, (4) berdasarkan pengamatan dan data yang diperoleh, sumber air baku (sungai Cikapundung, Bantar Awi) masih memenuhi standar kualitas air baku untuk air minum, Peraturan Pemerintah No. 82, 2001 meskipun terdapat beberapa parameter yang terkadang tidak memenuhi baku mutu salah satunya adalah residu tersuspensi, namun setelah melewati proses pengolahan air yang diproduksi sudah memenuhi baku mutu, (5) berdasarkan kesesuaian pada criteria desain, maka bak prasedimentasi membutuhkan penambahan waktu detensi dan pelebaran agar kinerja unit prasedimentasi ini bisa lebih dioptimalkan dalam mengatasi fluktuasi ke keruhan air baku pada saat musim penghujan.

Abstract

Babakan Village has a problem that there is still a lack of facilities for wastewater. This condition can be seen from the access to the toilets of 2436 households; only around 1506 families have access to family/ shared latrines and 625 households that meet technical requirements. For this reason, this plan is useful for increasing access and meeting community needs for domestic wastewater treatment facilities in the study area. This planning stage begins with a survey and sanitation inspection to determine 3 priority areas for handling. Determinants of this priority area use the method of scoring and weighting the risk. The weighting results put sub village 02 with a score of 2.3, sub village 05 with a score of 2.25, and RW 10 with a risk value of 2 as the priority area for planning handlers. Primary data collected will be used as a consideration for determining the technology to be applied. The technology chosen for processing is the communal septic tank for people who do not have treatment. In contrast, for the washing bath, toilet with a biofilter unit for people who do not have wastewater infrastructure.

Abstract

The role of water in daily life, including activities in the mosque is very significant. The existence of the Ulul Albaab Mosque which is always busy with various congregation activities and activities carried out by students and the campus community affects the need for clean water. So far, the ablution used water at the Ulul Albaab Mosque has been dumped into the sewers. Measuring the quantity of water to determine the volume of ablution used water at the time of obligatory prayer is the first step to assessing its potential utilization. The number of congregation who perform ablution is directly proportional to the number of congregation of the Ulul Albaab Mosque. The average congregation of the mosque is 857 people/day and the average number who perform ablution is 778 people/day. The results showed that the volume of water used for ablution was 3.9 liters/person with an average time required for ablution of around 64 seconds. The use of recycling ablution water can be used for non-consumption needs.
