Earthquakes frequently cause significant damage to residential buildings and lead to loss of life. As a result, houses in earthquake-prone areas must adhere to earthquake-resistant building codes. Recently, RISHA (Simple Healthy Instant House), developed by PUSKIM (Center for Settlement Research and Housing Development), has been commonly implemented as housing in areas impacted by earthquakes, including East Nusa Tenggara, West Nusa Tenggara, Aceh, and Cianjur Regency, RISHA homes have been provided to residents in relocation areas. This study aims to assess the viability of using RISHA as a replacement for conventional houses in Cianjur Regency. The analysis predicts the structural response of RISHA and conventional houses to the Cianjur earthquake, using the spectrum response method based on SNI 1726:2019. Using SAP2000 software, the study evaluates deflection, bending moment, and base shear force. The findings indicate that RISHA exhibits lower deflection, bending moment, and shear force compared to conventional houses, with values being 12.5%, 65%, and 66.5% of those in traditional houses, respectively. Based on these results, it is concluded that RISHA offers superior structural performance in resisting earthquakes compared to conventional residential buildings. © Published under licence by IOP Publishing Ltd.

Despite being an efficient bioremediation agent, aquatic biofilm's usefulness as a biomonitor has not been explored extensively. This study disclosed the potential of epilithic biofilm as biomonitor by comparing its metagenomics with water quality parameters and microplastic count in Brantas River. Metagenomics showed the epilithic biofilm was dominated by Exiguobacterium, which recognizes and degrades microplastics, along with Rhodobacterium and Rhizobiales. For the first time, biofilm microbes and their respective roles were discovered to correspond to the total microplastic counts in comparison with BOD as the only transgressing physicochemical parameter. Thus, epilithic biofilm is a potential biomonitor for riverine microplastic contaminations. © 2024 The Author(s)

It is undeniable that microplastics are found in many types of water, including drinking water. This study aims to investigate the presence of microplastics in one of the drinking waters widely used by communities in Indonesia, known as unbranded refilled drinking water. The investigation was conducted at eight unbranded refilled drinking water depots in Karawang, West Java. A total of 2.00 L of raw air and processed water samples were taken from each depot, then prepared by the National Oceanic and Atmospheric Administration, analyzed using an Olympus BX - 41 microscope with a magnification of ten times, and then counted manually. The results showed that raw and processed water in all unbranded refilled drinking water depots contained microplastics with details of 15.50-42.00 particles/L and 6.50-17.50 particles/L, respectively. The dominant microplastics found were fibers and fragments with sizes of 1.00-3.00 mm and less than 1.00 mm. Furthermore, the dominant color of the microplastics was black, indicating that the polymers of microplastics were polyethylene, polypropylene, or polystyrene. This finding has confirmed that refilled drinking water consumed by the community in Indonesia has potentially become one of the main pathways for the entry and accumulation of microplastics into the human body, posing significant health risks. Based on current research, further research is needed to improve water treatment performance to protect public health. © 2025, The Authors. All rights reserved.

The consistency and effectively trap of microplastics (MPs) removal in recent studies on the water treatment stages of wastewater treatment plants (WWTPs) has achieved up to 90 % and diverted the retained MPs which then settled into sewage sludge (SS). However, the effects of SS treatment stages and spatiotemporal factors can influence the concentration of MPs and remain insufficiently understood. This study investigates the presence and spatiotemporal patterns of MPs in six WWTPs in Taiwan, especially on SS. This study also assesses diversities and ecological risks, providing insights into the distributions and potential dangers of these pollutants. It was found that the concentration of MPs in SS has a range of 32.79-85.06 × 103 items/kg DW. The characteristics of color, shape, size, and polymer are mostly white (26.19 %), fiber (43.25 %), 50-125 μm (54.15 %), and polystyrene (41.35 %), respectively. Furthermore, due to increased anthropogenic activities in the summer season, the MPs level was significantly higher (11.22 %) compared to winter. Diversities and risks of MPs in spatial and temporal conditions were significantly different. Among ecological risks implemented in this study, belt filter press (s6) possessed the highest HI value (level IV). For PLI, all samples had a value of © 2025 Elsevier Ltd.

Sugarcane bagasse, with a 25–28 % lignin content, can be converted into biochar, serving as a promising adsorbent due to its high surface area. Nano-zero-valent iron (nZVI) is known for its strong magnetization and ability to bind heavy metals. In this research, biochar derived from sugarcane bagasse was composited with nZVI at varying ratios (1:1, 2:1, and 3:1) to improve adsorption efficiency for Cr (VI) removal. The composites were synthesized using the biochar from the plasma pyrolysis method, followed by nZVI incorporation. Batch adsorption tests were conducted with different Cr (VI) concentrations, contact times, pH levels, and adsorbent doses to determine the optimum conditions for each ratio. Characterization of the adsorbent included XRD, BET, FTIR, SEM, VSM, and Zeta potential analysis. XRD analysis of sugarcane bagasse and biochar demonstrated crystallinity and particle size improvements post-pyrolysis. BET results showed that sugarcane bagasse biomass had a surface area of 0.061 m²/g, which increased to 87.50 m²/g after conversion to biochar. However, once composited with nZVI, the surface area decreased to 37.44 m²/g (1:1), 49.26 m²/g (2:1), and 62.37 m²/g (3:1). FTIR and SEM analyses revealed the interactions between biochar and nZVI, as well as the binding of Cr (VI) to the composite surfaces. VSM showed a reduction in magnetization after adsorption, confirming the oxidation of nZVI to various iron oxides (e.g., FeO, Fe₂O₃, Fe₃O₄), which are less magnetic. The adsorption tests indicated that the adsorption capacity increased with a higher SBB/nZVI ratio. The biochar alone had an adsorption capacity of 77.82 mg/g. In comparison, the composites achieved 86.47 mg/g (1:1), 95.12 mg/g (2:1), and 112.41 mg/g (3:1). Optimal removal was achieved at an initial Cr (VI) concentration of 175 mg/L, a contact time of 180 minutes, and a pH of 2. The Langmuir isotherm model best described the adsorption behavior,

Persulfate-based advanced oxidation processes have emerged as promising technologies for mitigating endocrine-disrupting chemicals (EDCs) in wastewater treatment. Economically viable Fe-based materials with tailored properties have demonstrated significant efficacy in activating persulfate for the decomposition of EDCs through both radical routes (∙OH, SO4∙−, and O2∙−) and non-radical routes (1O2, surface activated PS complex, and high-valent Fe species). This review summarized the latest advancements in the persulfate activation mechanisms mediated by Fe-based materials, categorized by Fe valence states and the types of reactive species. Furthermore, it critically assesses the influence of active sites of Fe-based catalysts on persulfate activation pathways and summarizes the selective reaction of reactive species towards EDCs. Despite these advancements, several challenges persist in non-radical route-dominated persulfate activation, particularly regarding the impact of Fe-Fe distance on the reactive species and the catalytic role of Fe-based materials for reactions between inorganic ions and persulfate. This review proposes prospective research directions, provides design strategies, and expands the application of Fe-based materials in PS activation for effective EDC abatement in real situations. © 2025 Elsevier B.V.

The marine cyanobacterium Synechococcus can accumulate significant amounts of silicon (Si) within its cells, potentially contributing to the vertical transport of biogenic Si in the ocean. This has prompted interest in understanding the uptake, subcellular distribution, and chemical forms of Si in Synechococcus. The surprisingly high intracellular Si concentration could have important impacts on Synechococcus physiology, but these effects have been relatively unexplored. In this study, we investigated the effects of external Si concentrations, [Si(OH)4], on the cell physiology of two strains of Synechococcus (CC9311 and WH7803). Increased ambient [Si(OH)4] significantly enhanced total cellular and water-soluble Si content in Synechococcus, but had little effect on their growth. However, the cell size, volume and photosynthetic performance were significantly reduced in strain WH7803, indicating some harmful effects in the cell. Increases in ambient [Si(OH)4] also altered the Derjaguin-Muller-Toporov (DMT) modulus, adhesion, surface potential and elemental composition of the Synechococcus cells. Notably, significant changes in area-specific adsorbed metals and volume-specific metal content were observed at higher [Si(OH)4] levels, suggesting Si availability in seawater could markedly impact the interactions between Synechococcus cell and environment. Overall, this study provides new insights into the physiological adaptations of marine cyanobacterium Synechococcus to varying environmental silicic acid concentrations. © 2025 Elsevier Ltd

The world's continuous demographic expansion has driven a growing demand for a stable food supply, making the agriculture sector a key foundation for sustainable food production. However, the widespread use of conventional fertilizers has resulted in significant environmental and economic drawbacks, including inefficient nutrient delivery and nutrient leaching. These challenges highlight the urgent need for innovative agricultural solutions. This article reviews the adverse impacts of conventional fertilizer use on ecosystems and discusses the transition to slow-release fertilizers (SRF) as a promising alternative. SRF offers more controlled nutrient release, reducing nutrient loss and improving efficiency compared to traditional fertilizers. The article examines different types of SRF, their mechanisms, advantages, limitations, and their potential to transform modern agriculture by addressing both environmental concerns and crop nutrient management. Key challenges, including high production costs and the use of non-biodegradable coatings, are addressed. This review highlights the potential of bio-based coatings as replacements for non-renewable petroleum-based materials in SRFs, promoting sustainable practices and reducing potential toxicity in agricultural applications. The evolution of SRFs into multifunctional fertilizers is also discussed, emphasizing their expanding roles beyond controlled nutrient release. © 2025 Elsevier Ltd

Heavy metal and microplastic pollutions are prevalent in freshwater ecosystems, with many freshwater bodies being contaminated by one or both of these pollutants. Recent studies reported extreme detections of Cd, Pb and Zn, high concentrations of Cr, Pb and Cu and microplastics acting as vectors of pollutants, including heavy metals. Mayflies can serve as bioindicators of heavy metal contamination in freshwater ecosystems because changes in their community structure, physiology, and behaviour can reflect and help predict the concentrations of metals in these environments. This review discusses the ecological alterations induced by tissue metal concentration in mayflies and other macroinvertebrates. As sensitive taxa to heavy metal contamination, mayflies can reflect the impacts of this pollution through their ethology and relationship to the substrate, highlighting issues such as eutrophication, alterations in community structure, inhibitory effects and sediment toxicity. Mayflies are also highly affected by microplastic exposure, which leads to ingestion, bioaccumulation, biomagnification, habitat and community alteration, behavioural changes, physiology alteration and toxicity. Mayflies bioindication metrics for assessing the impact of heavy metals and microplastics include the examination of community alteration, functional feeding behaviour, molecular structure, dietary and toxicity impacts, bioaccumulation and biomagnification and biomarkers. Current challenges for the utilization of mayflies as bioindicators include temporal variations in sensitivity, lack of universally recognised protocols and need for standardised protocols for microplastic analysis. Additionally, the applicability of mayflies as bioindicators may vary across different ecosystems, emphasising the need for selecting suitable indicators that align with the unique characteristics of the ecosystem. © 2024 The Authors
