Abstract

Kapasitas pengolahan air limbah harus menampung debit air limbah yang dihasilkan oleh Kota Harapan Indah agar tidak memberi dampak negatif terhadap lingkungan. Pembuatan IPAL direncanakan dapat berfungsi sampai 20 tahun ke depan dengan mengacu pada data debit air limbah yang dihasilkan. Metode yang digunakan dalam penentuan debit air limbah domestik ini meliputi data jumlah penduduk, kebutuhan air bersih yang berasal dari data sekunder. Perhitungan proyeksi penduduk dari tahun 2018-2041 menggunakan metode terpilih yaitu metode aritmatika. Berdasarkan hasil perhitungan proyeksi penduduk dengan metode terpilih, jumlah penduduk pada 20 tahun mendatang yaitu tahun 2041 adalah 918.954 jiwa. Timbulan air limbah CBD Kota Harapan Indah di akhir tahun perencanaan adalah 1.940 L/detik.  Kapasitas IPAL yang direncanakan harus dapat menampung debit minimal 1.940 L/detik agar tidak terjadi overflow, sedangkan di awal tahun perencanaan, debit air limbah yang kurang harus ditambahkan penggelontoran agar proses pengolahan di IPAL dapat berjalan dengan lancar. Pemilihan alternatif menggunakan metode scoring dengan unit IPAL yang terpilih diantaranya bar screen, grease trap, screw pump, grit chamber, bak ekualisasi, aerasi, clarifier, dan disinfeksi.

Abstract

Domestic wastewater service with a piped system by PDAM Kota Bandung currently has not reached evenly and thoroughly to remote residential areas. In 2008, PDAM collaborated with the Environmental Services Program-United States Agency for International Development (ESP-USAID) built MCK Plus (MCK equipped with a bio-digester septic tank). This research was conducted at RW 07 Tamansari, Lebak Siliwangi Village, Bandung City and was carried out in March-May 2023. The data collected was primary data from observations, questionnaires, and interviews, while secondary data from literature studies. The survey results found that 8 MCK were abandoned and had been used as storage areas (warehouses) as well as chicken coops. For the service of 35 households, the required rectangular septic tank are 3.2 m wide, 9.6 m long, 3.2m high and the volume of the septic tank is 61.5m3. From the calculation results, the biogas produced per day can be used for cooking activities for a maximum of 2 people. Septic tanks as a technology for treating wastewater have a good impact on society if used effectively. To get the maximum potential from implementing a septic tank, it requires not only community participation, but also collaborative government institutions to support this program.
