Abstract

Limbah cair batik adalah limbah yang dihasilkan dari proses pemutihan, pewarnaan, percetakan, pencelupan, pengeringan, dan pencucian yang menyebabkan limbah tersebut memiliki karakteristik pH, BOD, COD dan TSS. Tujuan penelitian ini yaitu (1) untuk mengukur kualitas limbah batik; (2) menguji kemampuan tanaman; (3) menganalisis pengaruh jumlah tanaman; (4) menganalisis pengaruh lamanya waktu tinggal Tanaman Kayu Apu (Pistia stratiotes L.) dalam menurunkan kadar BOD, COD dan TSS pada air limbah batik menggunakan metode hidroponik rakit apung. Variasi yang digunakan pada penelitian ini yaitu, 0 tanaman, 4 tanaman dan 8 tanaman dengan waktu kontak 1 hari, 3 hari dan 7 hari. Konsentrasi awal BOD, COD dan TSS sebelum perlakuan adalah 542 mg/L, 1043 mg/L dan 664 mg/L. Hasil analisis menunjukkan bahwa jumlah tanaman dan lama waktu tinggal berpengaruh terhadap penurunan kadar pencemar pada limbah cair batik. Penurunan kadar pencemar yang paling efektif terjadi pada hari ke 3 dengan jumlah 4 tanaman dengan persentase BOD sebesar 96,31% ; COD sebesar 96,07% ; TSS sebesar 97,74%. Hasil pengukuran juga menunjukkan bahwa efektifitas penurunan kadar pencemar ditentukan oleh jumlah tanaman dan waktu tinggal semakin sedikit jumlah tanaman dan singkatnya waktu tinggal maka semakin efekif dalam menurunkan BOD, COD dan TSS.

Abstract

This research is conducted on a laboratory scale. The wastewater used in this study is raw wastewater collected from the wastewater treatment plant (WWTP) of an industrial area. The wastewater was taken from the equalization tank unit, while the microbial inoculum was taken from the clarifier unit. The MBBR reactor was built from PVC pipe with a volume of 10 L, filled with 20% Kaldnes K1 media and 80% wastewater based on reactor volume. The MBBR effluent was measured for pH, BOD5, COD, and NH₃-N over eleven days. The research results show that the industrial area wastewater at NIP exceeded the quality standards for COD, BOD₅, NH₃-N, and NO₃-N parameters. Wastewater treatment using MBBR technology with Kaldnes K1 media achieved removal efficiencies of 71.8%, 83.5%, and 69.6% for BOD5, COD, and NH₃-N, respectively. The MBBR biological treatment reduced BOD5, COD, and NH₃-N values from 160.6 mg/L, 379.1 mg/L, and 26 mg/L to 42.5 mg/L, 62.4 mg/L, and 7.9 mg/L, respectively. The MBBR effluent from industrial area wastewater treatment has met the applicable quality standards. MBBR technology is a promising wastewater treatment method suitable for various types of wastewater.

Abstract

The Water Treatment Plant (WTP) Ngagel 1 built in 1922 and is still in operation today. There are six rapid sand filter units, namely filters A, B, C, D, E, and F. Each filter unit consists of 32 rapid sand filter beds. The problem faced by the rapid sand filter unit is the reduction in the thickness of the silica sand media. Therefore, this field study aims to determine the correlation between the thickness of the silica sand media and the efficiency of turbidity reduction. This study is a field study, where data collection was carried out at the WTP Ngagel 1 rapid sand filter building unit. Water samples were taken from each rapid sand filter grid in the Rapid Sand Filter buildings A, B, C, D, E, and F. The height of the silica sand media was measured in each rapid sand filter grid. Water samples were taken at the inlet and outlet of each rapid sand filter section to measure turbidity in the laboratory. This field study concluded that the efficiency of turbidity reduction by rapid sand filters is influenced by the thickness of the silica sand media, with an average correlation value of 0.72 for the six rapid sand filter units.Keywords: media thickness, rapid sand filter, silica sand, turbidity

Abstract

Intensive vannamei shrimp (Litopenaeus vannamei) farming produces wastewater with high organic and nutrient loads, which can contaminate surrounding waters without proper treatment. This study designs a Wastewater Treatment Plant (WWTP) for X Firm’s intensive shrimp ponds in Campurejo Village, Panceng District, Gresik Regency, ensuring the effluent meets the quality standards set by the Regulation of the Minister of Marine Affairs and Fisheries No. 28 of 2004. The design process uses laboratory test results of wastewater characteristics and operational analysis of the ponds. The Analytical Hierarchy Process (AHP) method determines treatment alternatives, identifying a combination of anaerobic–aerobic biofilter processes as the most effective based on technical feasibility, pollutant removal efficiency, and land requirements. The proposed WWTP includes an equalization pond, anaerobic biofilter 1, anaerobic biofilter 2, aerobic biofilter, and a final sedimentation pond. It has a treatment capacity of 1,405.7 m³/day, with retention times optimized for each unit. The design requires 534.88 m² of land. Keywords: WWTP, Intensive Vannamei Shrimp Farming, Anaerobic-Aerobic Biofilter, Wastewater, Gresik Regency
