Abstract

Laundry business activities produce waste water from the washing process and have the potential to pollute water bodies. The number of domestic laundry activities is currently experiencing significant growth, as these activities increase, the amount of waste water released is also increasing. So far, the waste water produced has been directly discharged into the environment. Initial testing of the sample showed that the results did not meet the threshold according to East Java Governor Regulation No. 72 of 2013, so it is necessary to treat waste water effectively. In this research, laundry wastewater was treated using an oxidation ditch. The multilevel modified Parit Oksidasi is made from an activated sludge unit. Seeding and acclimatization takes 14 days to obtain optimum processing. The best variation uses 3 wavemaker units to reduce COD by 91.87%, phosphate by 98.49% and TDS by 57.21%. Apart from that, other contents in the sludge were also identified, namely oxygen (44.28%), carbon (21.25%), sodium (9.73%), calcium (7.11%), silica ( 4.46%), Sulfide (4.36%), Magnesium (2.73%), Chlorine (2.68%), Potassium (1.59%), Iron (0.61) and Phosphorus (0.07 %).

Abstract

Pineapple peel waste (Ananas comosus) is a source of organic waste with high lignocellulose content that has the potential to be utilized through a bioconversion process into glucose. This study aims to determine the Michaelis–Menten kinetic equation of cellulose hydrolysis into glucose using cellulase enzymes and analyze the effect of substrate concentration (1–5% w/v) and hydrolysis time (60–180 minutes) on the reaction rate. The research stages include delignification using 5% NaOH at 80ºC and enzymatic hydrolysis with 10% cellulase at pH 5 and 50ºC. Glucose levels were measured using a Brix refractometer through a standard glucose solution calibration method. The results showed an increase in glucose concentration over time and substrate concentration, with the highest conversion of 91.5% at 5% substrate. Kinetic analysis using the Michaelis–Menten equation yielded an average reaction rate constant (k) of 0.3328 min⁻¹, with the highest k of 0.3828 min⁻¹ and the highest Michaelis–Menten constant ( ) of 2.357 mg·L⁻¹ at a substrate concentration of 5%. A significant increase in  from 0.2403 (1%) to 2.357 (5%) indicates a decrease in enzyme affinity due to substrate saturation. Therefore, a concentration of 5% is considered the optimal condition for the cellulose hydrolysis process, confirming the potential of pineapple peel waste as an efficient substrate source.

Abstract

This study aims to evaluate the performance of aluminum sulfate (alum) coagulant in river water, tofu waste, and batik waste with varying doses on the effectiveness of the coagulation-flocculation process. The method used was a jar test on 1000 mL of water samples, including coagulation for 1 minute at 120 rpm, and flocculation for 20 minutes at 40 rpm, and sedimentation for 15 minutes. The variations in alum doses used were 150 mg/L, 200 mg/L, and 250 mg/L. The results showed that this process caused pH changes during treatment and was effective in reducing turbidity, TSS, and color although the optimum dose differed for each sample. In river water, the optimum dose of 150 mg/L resulted in 98.99% turbidity removal, 81.82% TSS removal, and 99.11% color removal. Meanwhile, for tofu waste, the optimum dose of 250 mg/L resulted in 86.67% turbidity removal, 98.66% TSS removal, and 96.16% color removal. Meanwhile, for batik waste, the optimum dose of 200 mg/L resulted in 97.89% turbidity removal, 95.76% TSS removal, and 91.61% color removal. This indicates that the coagulant dosage needs to be adjusted to the characteristics of each type of sample used.

Abstract

Universitas Pembangunan Nasional "Veteran" Jawa Timur (UPNVJT) is committed to realizing a sustainable campus. However, this commitment was challenged at the Warung NKRI canteen, where liquid waste was discharged into open sewers, causing pollution and odor. This Community Service Program aimed to solve this issue through a multidisciplinary approach. The methods included educating vendors and customers on waste management and implementing a Wastewater Treatment Plant (WWTP/IPAL). To ensure sustainability, socialization on system maintenance was conducted for the Business Management Unit (BPU) and cleaning service staff. The results showed increased awareness within the canteen community and the WWTP's success in producing clearer, odorless effluent. This program proves that cross-disciplinary collaboration can deliver tangible and sustainable solutions for campus environmental sanitation.

Abstract

Wastewater from the Sludge Treatment Plant (IPLT) often contains hazardous contaminants that can pollute water bodies if discharged without prior treatment. Wastewater treatment from the IPLT, especially the Oxidation Ditch outlet, can be carried out using one of the Advanced Oxidation Processes (AOPs), namely Fenton. This study aims to analyze the effectiveness of the Fotofenton method in the Oxidation Ditch outlet unit of the Keputih IPLT, Surabaya, on total coliform, COD, and TSS parameters. The total coliform removal percentage was 98%, the COD parameters were 82%, and the TSS parameters were 60% at a dose of FeSO4: H2O2 molar ratio of 1:15, UV lamp power of 20 watts, and sampling time of 60 minutes. This study demonstrates that the Fotofenton method can be an environmentally friendly solution for wastewater treatment from IPLT and can be applied as an advanced treatment stage to meet applicable quality standards.

Abstract

Population growth in Indonesia poses sanitation challenges, where Sewage Sludge Treatment Plants (IPLT) provide a solution for sewage waste treatment. However, IPLTs themselves still face obstacles in optimally removing contaminants such as ammonia, Total coliform bacteria, and COD. This study evaluates the effectiveness of advanced oxidation processes (AOPs) combining hydrogen peroxide and ultraviolet light (H2O2-UV) in degrading these three pollutants. The wastewater used in this study came from the outlet of the Final Clarifier unit. The experiments were conducted in a continuous reactor with varying concentrations of H2O2 (0.1%-0.7%) and UV light contact time (15-45 minutes). The results showed that the highest degradation efficiency was achieved at a H?O? concentration of 0.7% for 45 minutes, with a removal percentage of 99.24% for Total Coliform bacteria and 88.32% for Ammonia. However, for COD, the highest degradation efficiency was achieved at a concentration of 0.5% for 45 minutes with a removal percentage of 79.55%. These results prove that the H2O2-UV process is effective in degrading IPLT wastewater pollutant mixtures through the production of non-selective hydroxyl radicals (•OH).

Parameter yang diamati meliputi pH, suhu, konsentrasi C-organik, dan jumlah koloni bakteri. Hasil menunjukkan peningkatan pertumbuhan bakteri secara signifikan pada fase logaritmik dengan pola linear hubungan antara ln(CA0/CA) dan ln(CC/CC0). Nilai koefisien determinasi (R²) mendekati 1, yang mengindikasikan kesesuaian dengan model kinetika pertumbuhan. Selain itu, terjadi penurunan kandungan C-organik dan logam berat, serta perubahan karakteristik fisik air lindi yang menunjukkan peningkatan kualitas hasil fermentasi. Dengan demikian, fermentasi air lindi menggunakan Pseudomonas fluorescens berpotensi mengurangi dampak pencemaran dan meningkatkan nilai guna air lindi sebagai hasil olahan ramah lingkungan. Abstract: Leachate is a liquid waste generated from the decomposition of solid waste in landfill sites, which has the potential to pollute the environment due to its high content of organic matter and heavy metals. This study aims to analyze the growth kinetics of Pseudomonas fluorescens and the physical characteristics of leachate after the fermentation process. The fermentation was carried out aerobically for 8 days with variations of bacterial inoculum volumes of 5 mL, 7 mL, and 10 mL in 100 mL of leachate. The observed parameters included pH, temperature, C-organic concentration, and bacterial colony count. The results showed a significant increase in bacterial growth during the logarithmic phase, following a linear relationship between ln(CA0/CA) and ln(CC/CC0). The determination coefficient (R²) values were close to 1, indicating good conformity with the microbial growth kinetics model. In addition, there was a reduction in C-organic and heavy metal contents, as well as changes in the physical characteristics of the leachate, indicating improved quality of the fermentation product. Therefore, leachate fermentation using Pseudomonas fluorescens has the potential to reduce environmental pollution and enhance the usability of leachate as an environmentally friendly processed product.
