PERENCANAAN INSTALASI PENGOLAHAN AIR LIMBAH (IPAL) INDUSTRI TAHU DI KELURAHAN LOKTABAT UTARA, KALIMANTAN SELATAN
Get PDFTofu is a soy-based culinary product. During the manufacturing process, the tofu industry generates solid refuse and liquid waste. The majority of the tofu industry lacks a sewage treatment infrastructure, so the resulting waste is discharged directly into the river. High levels of organic pollutants are present in liquid waste, which can cause significant pollution. The effluents discharged into the water must meet the established quality requirements. If the water discharged does not meet quality standards, it will pollute the environment. This research aims to evaluate the quality of wastewater produced by the tofu industry, as well as determine the most suitable treatment technology for the waste conditions and design a wastewater treatment plant (WWTP). The tofu industry's liquid effluent contains 2666.5 mg/L BOD, 12476.1 mg/L COD, and 3220.3 mg/L TSS. The selection of WWTP technology utilizes a scoring method based on criteria provided by the Technical Team for Sanitation Development. The chosen treatment unit is an Anaerobic-Aerobic Biofilter with a score of 4.3. The design of the WWTP model includes an equalization tank, initial sedimentation tank, anaerobic biofilter tank, aerobic biofilter tank, and final sedimentation tank.Tahu merupakan produk kuliner berbahan dasar kedelai. Selama proses pembuatannya, industri tahu menghasilkan sampah padat dan limbah cair. Sebagian besar industri tahu tidak memiliki infrastruktur pengolahan limbah, sehingga limbah yang dihasilkan dibuang langsung ke sungai. Tingkat polutan organik yang tinggi hadir dalam limbah cair, yang dapat menyebabkan polusi yang signifikan. Limbah yang dibuang ke air harus memenuhi persyaratan kualitas yang ditetapkan. Jika air yang dibuang tidak memenuhi baku mutu, maka akan mencemari lingkungan. Penelitian ini bertujuan untuk mengevaluasi kualitas air limbah yang dihasilkan oleh industri tahu, serta menentukan teknologi pengolahan yang paling sesuai dengan kondisi limbah tersebut dan merancang instalasi pengolahan air limbah (IPAL). Limbah cair industri tahu mengandung BOD 2666,5 mg/L, COD 12476,1 mg/L, dan TSS 3220,3 mg/L. Pemilihan teknologi IPAL menggunakan metode skoring, dengan kriteria penilaian yang bersumber dari Tim Teknis Pengembangan Sanitasi. Unit pengolahan yang dipilih adalah Biofilter Anaerobik-Aerobik dengan skor 4,3. Rancangan bangunan IPAL mencakup bak ekualisasi, bak sedimentasi awal, bak biofilter anaerobik, bak biofilter aerobik, dan bak sedimentasi akhir

Get PDFThe Drinking Water Supply System (SPAM) has an important role in people's lives. PDAM Bandarmasih Banjarmasin City is a service company that manages and distributes clean water. The East Banjarmasin Zone is included in the Pramuka IPA II service. There are quite a lot of house connections causing the distribution process to experience a pressure drop so that the water has not been distributed to all customers. The total water requirement is 689.36 L/second. For this reason, an analysis of pressure parameters and headloss units was carried out on the existing primary pipe network model and processed using Epanet 2.2. The results of the analysis that do not meet the standards will be carried out with 3 alternative simulations to increase the performance of the distribution network system. The results of the evaluation of the existing condition of the East Banjarmasin zone found that 82% pressure and 7% headloss units did not meet the standards. Alternative 1 simulation, namely changing pump capacity can increase 100% of pressure and 93% of headloss units meet the standard. Alternative 2, namely replacing and parallelizing the pipe can increase 97% pressure and 98% headloss according to standards. The planned pipe diameter ranges from 200-630 mm with a length of 22,565 m. Alternative 3, namely adding an inline pump and adding pipes can increase 93% pressure and 97% headloss units meet the standard. Recommendations made for the long term are a combination of alternatives 1 and 2. This combination of alternatives produces pressures ranging from 9 – 43 mka, which means that it is still within the reference standard range of PERMEN PU No.18 of 2007.Sistem Penyediaan Air Minum (SPAM) mempunyai peran penting dikehidupan masyarakat.
