Abstract

The aim of this research is to determine the feasibility of producing environmentally friendly briquettes using organic waste and coconut shells as the main ingredients. 3 (three) briquette compositions, including: (1) 25% organic waste, equivalent to 75% coconut shell; (2) 75% organic waste, 25 percent coconut shell; and (3) 50% organic waste, 50 percent coconut shells. The research method used to analyze the water content, ash content and heating value of briquettes is a quantitative research method. The results of this research show that organic waste and coconut shells can be converted into environmentally friendly briquettes. Briquettes with a mixture composition of 75%:25% have a reduced ash percentage. Meanwhile, mixed briquettes containing 25%:75% have a low water content, meaning more coconut shell, the lower the water content and the better the properties of the briquettes.

Abstract

Sewage sludge is a major by-product of the wastewater biological treatment process. Wastewater Treatment Plants at Palm Oil Mills (PKS) produce a lot of sewage sludge and until now it has not been optimally utilized. This study aims to examine the potential of PKS sewage sludge as an adsorbent for the removal of kromium (Cr) by the fixed bed column method. The study will also analyze the effect of recirculation on the reduction of kromium levels. The sludge was carbonized in a furnace at 300°C for 2 hours. Synthetic kromium wastewater was made at three concentrations of 2000 ppm, 3000 ppm, and 4000 ppm. The sludge adsorbent used was 100 grams which was filled into the fix bed column. Recirculation of kromium wastewater was performed 3 times. Adsorption isotherms were analyzed using Langmuir and Freundlich models. The results showed that the best removal without recirculation occurred at a kromium concentration of 3000 ppm with a removal efficiency of 48.07%. Furthermore, recirculation was carried out 3 times and resulted in varying removal values at the 1st, 2nd, and 3rd recirculation of 37.9%, 40.06% and 35.4%. The highest removal occurred in the second recirculation. The addition of recirculation led to a decrease in the sorption of chrome as the adsorbent had reached saturation point. This allows the release of kromium ions that have been adsorbed and causes the removal efficiency to decrease. A suitable adsorption isotherm model for sludge adsorbent is the Langmuir model, where the adsorption process occurs in a single layer and is homogeneous.

Abstract

Rubber manufacturing operations inevitably yield effluent and solid residues bearing environmentally detrimental characteristics if left inadequately managed. Valorization of rubber shaving residues into activated carbon represents a compelling remediation pathway. This investigation scrutinized the influence of functional moieties within rubber shaving-derived activated carbon upon rubber mill effluent parameters through an experimental quantitative-qualitative design. Physicochemical attributes were elucidated via FTIR to delineate surface-bound functional assemblages, whilst remediation efficacy was appraised against BOD, TSS, and pH indices. Spectroscopic interrogation revealed oxygen-enriched moieties encompassing hydroxyl (-OH), carbonyl (-C=O), and ether (-C-O) constituents, each exerting a pivotal role in adsorptive mechanisms. Notwithstanding anomalous BOD elevation in non-activated specimens, NaOH 10% activation demonstrably consolidated functional assemblages, substantially curtailing BOD concentrations. This study affirms that rubber shaving-derived activated carbon constitutes an efficacious and ecologically benign adsorbent, wherein judicious activation optimization emerges as the cardinal determinant of successful pollutant abatement.

Abstract

The treatment of domestic wastewater in communal systems currently faces many challenges, including a decline in treatment performance due to the high pollutant load entering the system, resulting from inadequate maintenance. Therefore, a system is needed to support the optimal performance of wastewater treatment plants (WWTPs), namely surface-flow wetlands (SF-Wetlands). This study aims to analyze the effect of retention time on the effectiveness of organic matter removal in surface-flow wetlands using Pistia stratiotes L. plants. The retention times used were 12, 24, 36, 48, 60, and 72 hours. The domestic wastewater parameters analyzed were BOD5 and ammonia. The results showed that the highest efficiency in reducing BOD5 concentration occurred at a retention time of 72 hours, with a reduction of 97.42% to 16.85 mg/L, while ammonia was reduced by 82.43% to 3.86 mg/L. The values achieved met the quality standards of PermenLHK Number 16 of 2016. Retention time significantly affects the removal of organic matter from domestic wastewater. An increase in retention time is needed to improve ammonia removal in the SF-wetlands system.

Abstract

Microplastics have been identified in rivers that supply raw water, particularly the Batang Merangin River, which supplies 90% of the treated water for Perumda Tirta Merangin. This situation has raised concerns about microplastic contamination in treated water. This study aims to describe the attributes of microplastics at the Water Treatment Plant (WTP) of Perumda Tirta Merangin, Merangin Regency. The study used a quantitative descriptive and experimental approach, examining water samples from each treatment unit (raw water intake, coagulation, flocculation, sedimentation, filtration, and reservoir) at the Ecoton Laboratory in Gresik. The results identified three categories of microplastics: fibers (47 particles), filaments (38 particles), and fragments (5 particles), for a total of 90 particles. The dominant color of microplastics was blue (39%), with sizes ranging from 2 mm.

Abstract

Waste lubricating oil from hair clipper machines generated by barbershop activities is a hazardous liquid waste containing oil and grease, suspended solids, and can alter the pH of aquatic environments if left untreated. This study aims to analyze the effectiveness of utilizing human hair waste as an adsorbent combined with the addition of hydrogen peroxide (H2O2) in improving the pH parameter of clipper engine oil waste. The research used an experimental method with a Magnetic stirrer at adsorbent weight variations of 5 g, 10 g, and 15 g and contact times of 30, 60, and 90 minutes. The results showed that the initial pH of 6.37 changed after treatment. The condition closest to neutral was obtained at the 10 g variation with a 30-minute contact time, namely pH 6.96 (9.26% efficiency), while the 5 g weight tended to raise the pH to alkaline (pH 8.48) and the 15 g weight lowered the pH to more acidic (pH 6.14). For the Total Suspended Solids (TSS) parameter, the initial value of 3,282.08 mg/L decreased significantly after treatment, with the lowest result at 5 g and a 60-minute contact time, namely 334.16 mg/L (89.82% efficiency). The addition of H2O2 played a role in the oxidation process affecting the pH stability of the treated waste.

Abstract

The problem of household waste has become so significant that it requires human resources to overcome it. To reduce pollution and recycle household waste, wastewater treatment facilities are needed. One of them is the International Paper Industry (IPAL) in Jambi City which uses APSDT (Antimicrobial photo-sonodynamic therapy) technology to treat domestic wastewater using moving bed biofilm reactor (MBBR) technology. To evaluate the quality of incoming and outgoing wastewater at the Jambi City IPAL, a study was conducted to measure pH (potential of Hydrogen), BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), TSS (Total Suspended Solid), Oil & Fat, Ammonia, and Total Coliform in accordance with Domestic Wastewater Quality Standards. Samples of the Jambi City IPAL were tested at the Jolli Lestari Internasional (JLI) Laboratory. The test results confirmed positive results for the TSS, Ammonia, and Total Coliform parameters, while the wastewater at the outlet also met the quality standards according to the Domestic Wastewater Quality Standards, except for the TSS parameter.

Abstract

The Kambang River is a river in Jambi City that passes through densely populated residential areas and shopping centers, making it vulnerable to pollution from both point and non-point sources. This study aims to model the water quality of the Kambang River using QUAL2Kw software on the Biochemical Oxygen Demand (BOD) and Ammonia as nitrogen (NH3-N) parameters in response to increasing discharge and pollutant levels from point sources. Sampling was conducted using grab sampling at nine points representing the upstream, midstream, and downstream segments. The test results were compared with the river water quality standards and similar waters, Class II, Appendix VI of Government Regulation No. 22 of 2021 concerning the Implementation of Environmental Protection and Management. River hydraulic data (discharge, width, depth, flow velocity, and riverbed slope) were used as input data in the QUAL2Kw worksheet. Data calibration was performed using trial and error, then data validation using the Root Mean Square Percentage Error (RMSPE) method. The results of water quality testing showed that the BOD and NH3-N parameters at all sampling points did not meet the established quality standards. The BOD test value ranged from 7.10 to 16.20 mg/L with a quality standard of 3.00 mg/L, and the NH3-N test results ranged from 3.03 to 14.13 mg/L with a quality standard of 0.20 mg/L. The model validation results using the RSMPE method for discharge parameters were 3.21%, BOD 3.88%, and NH3-N 0.46%, meeting the criteria of
