Abstract

Water is a crucial asset and serves as a significant factor in the quality of life, especially in supporting key sectors such as agriculture, energy, industry and conservation of natural ecosystems. Water quality can be significantly affected by pollution from effluents, especially in developing countries such as Indonesia which faces the added challenge of rapid population growth. This research focuses on monitoring water quality in the Garang River Sub-region, Semarang, by utilizing Internet of Things (IoT) technology for real-time monitoring. The methods used include the Storm Water Management Model (SWMM) model and an IoT-based monitoring system to measure important parameters such as temperature, pH, turbidity, Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), and nitrate and phosphate concentrations. The results showed that the Chemical Oxygen Demand (COD) parameter often exceeded quality standards, especially in areas with domestic and industrial activities. The IoT monitoring system facilitates precise and instantaneous data gathering., supporting sustainable water resources management. This research emphasizes the need for evaluation and adjustment of policies related to waste management and spatial planning to reduce pollution and improve water quality.

Abstract

Surakarta City is traversed by the Bengawan Solo River Sub-Basin which includes Kali Pepe River, Gajah Putih River, Kali Anyar River, Jenes River, and Premulung River. This condition results in the main burden of river water pollution coming from anthropogenic activities, both domestic and industrial. This study aims to examine the influence of urban area dynamics on river health with a case study of Surakarta City. This study used qualitative descriptive method. Data collection was carried out through observation techniques, and depth interviews. The results showed that there are three factors that affect river health, namely population increase, industrial and domestic activities, and public perception and participation. Surakarta City is one of the areas that contributes to river pollution from moderate to severe levels. However, there have been many efforts to evaluate river health by the local government, namely by normalizing riverbanks, controlling waste pollution, and other river management programs.

Abstract

This study investigates the utilization of solid waste from slag and aluminum cans as sources of valuable raw materials, along with bittern waste for magnesium oxide (MgO)cons production. Slag, a byproduct of industrial combustion in the palm oil industry, and aluminum cans, generated from human consumption in urban areas, were both subjected to leaching processes to recover silica (SiO₂) and alumina (Al₂O₃), respectively. The leaching of slag using 4 M NaOH yielded 85.68% SiO₂, while aluminum cans treated with 4 M HCl produced 85.90% Al₂O₃. Additionally, the study extracted MgO from bittern waste via precipitation, resulting in 76.98% MgO. X-ray fluorescence (XRF) analysis was employed used to determine the composition of the slag, aluminum can waste, and bittern, while X-ray diffraction (XRD) analysis confirmed the crystallinity of the recovered materials. The integration of recycled materials into the production of cordierite ceramics represents an innovative approach to waste valorization, offering potential for the development of advanced materials from industrial and urban waste. This research highlights the potential for valorizing industrial and municipal solid wastes through chemical processes, contributing to sustainable resource recovery and environmental conservation.

Abstract

Advanced sludge treatment remains a critical challenge as global wastewater production increases, with waste-activated sludge (WAS) posing ecological and health risks due to heavy metal accumulation. This study characterized WAS based on solid parameters and metal content, focusing on As, Cd, Cr, Cu, Fe, Pb, Ni, Mg, Mn, and Zn, which exceed organic fertilizer thresholds. Using Visual MINTEQ, heavy metal leaching behavior was modelled under pH-independent and pH-dependent conditions. The pH-independent simulation identified As as the least leachable metal (2.166 × 10⁻¹³ mgAs/L) and Cu as the most leachable (1.261 × 10⁻⁴ mgCu/L). The pH-dependent simulation (pH 1.5–13.5) revealed significant leaching for Fe (21.777 mgFe/L) and Cu (1.98 ×10-3 mgCu/L), with Ni (0.120 mgNi/L) and Pb (2.7 × 10-4 mgPb/L) posing chronic risks to aquatic ecosystems. Metals like Cr, Cd, and Ni exhibited distinct leaching patterns influenced by pH and WAS composition. The findings highlight the critical role of pH, along with WAS composition, in governing heavy metal leaching, providing insights to mitigate risks and support sustainable sludge management practices.

Abstract

Lack of drinking water is a condition where the availability of clean water is insufficient to meet basic human needs. This study aims to build a rainwater treatment system based on the Passive Infrared (PIR) HC-SR501 sensor and the Arduino Uno device. The method used is the applied experimental method. The results of the study showed that the content of rainwater seen from the physical, chemical and biological properties after the filtration process was as follows: temperature 27.4 ° C, total dissolved solids (TDS) 163 mg/l, turbidity 1.31 NTU, color 0 TCU -> 0 TCU, odorless, pH 8.1, nitrate (as NO3) 0.7 mg/l, nitrate (as NO2) 0.12 mg/l, Chromium Valence 6 (Cr6+) 0 mg/l, Iron (Fe) 0.61 mg/l, Manganese (Mn) 0.03 mg/l, Chlorine Residue 0 mg/l, Arsenic (As) not detected, Cadmium (Cd) 0.060 mg/l, Lead (Pb) 0.06 mg/l, Fluoride (F) 0 mg/l, Aluminum 0.05 mg/l, Total Coliform 4 CFU/100ml, E.coli 0 CFU/100ml. This data shows that rainwater has changed from not drinkable to drinkable although there are some shortcomings that require modification, namely in the Ultraviolet lamp. The modified filtration treatment design can optimize the physical, chemical, and biological properties of the air.

Abstract

Textile industry wastewater often contains persistent pollutants like neutral red dye, which are challenging to break down and harmful to ecosystems. This study introduces oxygen-doped graphitic carbon nitride (O-g-C3N4) as a photocatalyst to degrade neutral red dye under visible light. Synthesized using a single-step calcination of urea, dicyandiamide, and oxalic acid, O- g-C3N4 was tested for its efficiency in neutral red removal through adsorption and photocatalytic degradation, both in light and dark conditions. Results showed that O- g-C3N4 quickly adsorbed the dye, reaching equilibrium in 30 minutes and achieving a maximum adsorption capacity of 1.86 mg g-1, surpassing bulk g-C3N4. Kinetic analysis indicated that adsorption followed a pseudo-second-order model, suggesting chemisorption as the primary mechanism. Under visible light, O- g-C3N4’s photocatalytic degradation reached 86% neutral red removal, compared to 51% with bulk g-C3N4, largely due to improved light absorption and reduced electron-hole recombination. Degradation of neutral red followed pseudo-first-order kinetics, with O- g-C3N4’s reaction rate three times greater than bulk g-C3N4. The Sips isotherm best fit the adsorption data, confirming heterogeneous active sites and multilayer adsorption. These findings highlight O- g-C3N4’s potential for environmental remediation.

Abstract

This study will optimize ZrCo as a catalyst applied to the surface of porous membranes to remove micropollutants, specifically ibuprofen. This method improves the reaction rate and accelerates the chain degradation of Ibuprofen, thereby preventing blockage caused by impurities in the membrane pores. The catalyst synthesis was performed using a hydrothermal method with ZrCl4 and CoCl2·6H2O as the primary materials. This method is employed to produce a high purity catalyst and yield a more stable catalyst. This research will measure the optimal catalyst through flux and removal efficiency during the membrane distillation process for 1 hour. Reaction conditions were adjusted using Air Gap Membrane Distillation at 80°C heating temperature, 4 L/min flow rate, and 1.5 mmol/L peroxymonosulfate as pre-oxidation. Experiments were conducted by comparing 9 types of catalysts, from which the best calcination temperature was selected for catalyst concentration optimization. Based on the flux and removal data tested statistically, the optimum catalyst type and calcination temperature were achieved at a 2:1 composition with a calcination temperature of 600°C, yielding flux and removal efficiency values of 7.0238 LMH and 98.53%. Meanwhile, the optimum catalyst concentration was obtained at 0.5 wt%, with flux and removal efficiency values of 8.05 LMH and 99.83%.

Abstract

Slums represent a complex issue found in various regions, including Southwest Aceh Regency, caused by poor management and inadequate settlement planning. This study analyzes the spatial patterns of slum areas in Southwest Aceh Regency and proposes management strategies. The research utilizes Moran's Index analysis and LISA to identify spatial clustering patterns of slum areas, complemented by SWOT analysis to determine suitable environmental management strategies. Moran's Index analysis of slums in Southwest Aceh Regency for 2014 and 2020 reveals a positive spatial autocorrelation with clustered pattern, but less concentration in 2020. LISA analysis shows the spatial distribution of slum areas in 2014 showed high-high (HH) clusters concentrated along coastal and mid-district regions, while in 2020, clustering shifted and became concentrated in the regency capital. Overall, the distribution of slums in 2020 appears more dispersed. The primary environmental management strategy recommended for slum upgrading in Southwest Aceh Regency a Defensive Strategy. This involves strengthening stakeholder collaboration to improve sanitation infrastructure, thereby mitigating disaster risks such as flooding; reorganizing residential areas to accommodate urbanization while attracting developers; and educating the community to enhance compliance with environmental regulations. Additionally, maintaining financing programs despite potential budget reductions is critical to ensuring sustainable living conditions.

Abstract

Wastewater treatment using traditional systems is considered expensive because it requires considerable energy and installation. The current study assessed the existence of a combination process that can reduce costs and is easy to operate. This study evaluates the performance of an anaerobic-aerobic biofilter system to treat industrial wastewater from cracker production. The combination of anaerobic and aerobic biofilters can significantly reduce Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD), which are important parameters for wastewater quality. Sampling was carried out on the influent channel of the fish cracker industry. Sampling uses the SNI 6989.59:2008 regulation in the form of a wastewater test sampling method. The results showed that the biofilter achieved BOD removal of up to 84.90% and COD reduction of more than 89.02% when operated with an extended Hydraulic Retention Time (HRT) of up to 24 h. The results also showed that in wastewater treatment, HRT optimization should be considered for maximum pollutant removal, as shorter retention times proved less effective in reducing COD and BOD organic loads. These findings suggest that anaerobic-aerobic biofilter systems are viable and scalable solutions for industries seeking efficient and environmentally friendly wastewater treatment options.
