Abstract

Many surface waters in the world are impounded by eutrophication due to the global warming phenomenon. This study analyzed the trophic level in the Bangka Strait, a busy pathway that connects two provinces (Bangka and South Sumatra) of Indonesia, using MODIS-Terra chlorophyll-a (Chl-a) data from the 2020 year. We applied the GIS analysis to generate Chl-a concentration and trophic state maps over the study area. The results of the study revealed that the mesotrophic, eutrophic, and oligotrophic status encompass 50%, 43%, and 7% of the Bangka Strait region, respectively. The highest concentration of Chl-a was observed in May (5.38 g/L), while the lowest was observed in September (3.02 g/L). Our study revealed that the high Chl-a concentration was primarily due to nutrient contributions from South Sumatra rivers. On the other hand, the COVID-19 restriction policy significantly reduced Chl-a from July to October. The trophic state of the Bangka Strait was at a mesotrophic level, and the major contributors to the trophic condition in the strait came from the coasts of South Sumatra, which mostly consisted of agricultural and aquacultural activities. These findings will be useful in developing an effective policy for monitoring and protecting surface waters from eutrophication events.

Abstract

The interactions between water and energy in Liberia under the water-energy nexus approach are considered in this study, focusing on the challenges and possibilities of these links. It assesses the climate-related issues concerning Liberian water systems including temperature, rainfalls, and available water amounts. It assesses the balance and the utilization of water in the climate change framework. Cross-sectional and meta-analysis model was used in this study. It addresses the vulnerability, particularly the damages to hydropower, energy production, and fisheries in Liberia. There are numerous water resources in Liberia however, there is a disconnect with regards to the availability of data and an effective water-energy monitoring. Additionally, also show coordination in water and energy projects. A sustainable use of water, an installation of eco-friendly electricity production sources and adaptation to climate changes is slowly being pursues as the country boast high renewable energy potential especially with regards to hydropower. The study finds high rainfall with projections that it may reduce and also limited access to water and electricity. The study also finds gradual increase in energy generation and a higher renewable energy generation. Finally, possible pathways for a multidimensional approach and technology including policing to continue sustaining Liberia under a complex climate-water-energy nexus are presented. These issues are questions of transformation within the relationships between energy systems, water resources, and climate transition.

Abstract

Urbanization is the result of persistent population increase, which turns formerly agrarian areas into industrial and service-based hubs. This change prompts concerns about environmental degradation, including flooding, declining agricultural output, and air pollution, as well as a rise in demand for residential real estate, a limited resource. Goal 11 of the Sustainable Development Agenda, ”Building Inclusive, Safe, Resilient, and Sustainable Cities and Communities” addresses these problems. However, a comprehensive LSA incorporating local climate aspects has not been conducted for Serang Regency, an area with significant population growth and diverse land characteristics. This study aims to map the spatial distribution of suitable residential land in Serang Regency; evaluate the suitability of current residential areas; and assess the alignment of settlement plans with suitability criteria in the spatial plan. Findings reveal that 65.5% of Serang Regency is suitable for residential use, while 32% is unsuitable. Currently, 71.2% of settlements are in suitable areas, and 28.2% are in unsuitable ones. Future settlement plans show 90.7% alignment with suitable areas. These results indicate that, while spatial planning in Serang Regency has generally guided appropriate residential development, some areas still require attention for sustainability. This study provides valuable insights for policymakers aiming to foster sustainable, safe, and comfortable living environments.

Abstract

The growth rate in agro-industrial sectors has both positive and negative effects on technological, social, and economic development. Agro-industry production generates substantial volumes of wastewater, primarily from the aqueous discharges of its manufacturing processes. Some of this wastewater contains harmful pollutants that endanger human life, health, and the sustainability of the environment and ecosystem. For example, wastewater from the bioethanol industry contains high concentrations of organic pollutants and recalcitrant compounds, with COD and BOD values exceeding 50,000 mg/L and 30,000 mg/L, respectively. The Fenton process is an oxidation method that generates hydroxyl radicals through the reaction between H2O2 and Fe2+ ions. These hydroxyl radicals are highly effective at breaking down recalcitrant compounds. In this study, a comparative analysis of recalcitrant wastewater treatment using Fenton and photo-Fenton oxidation processes was conducted. The effects of dilution factors, or initial concentrations of recalcitrant wastewater (1:25, 1:50, and 1:75), were examined. Higher dilution ratios enhanced the degradation of COD and BOD levels in wastewater, with the optimal dilution factor for both processes being 1:75. Under optimal conditions, the removal efficiencies for COD, BOD, potassium, and phenol were in the range of 72.29-99.99%. The photo-Fenton process demonstrated higher removal efficiency compared to the Fenton process. The conclusion from this study suggests that the photo-Fenton process could be successfully employed as an advanced treatment method for effectively breaking down recalcitrant wastewater. These findings could be useful for adapting these processes to field-scale applications.

Abstract

This study investigates the synthesis and characterization of ZnAl-layered double hydroxide (ZnAl@LDH) composites modified with Eucheuma cottonii (EC) for the adsorption and regeneration of congo red (CR) dye. The ZnAl@LDH was synthesized using a co-precipitation method, and the composite with EC was prepared via hydrothermal techniques. The structural properties of the composites were analyzed using XRD and FTIR. Adsorption experiments were conducted to determine the effects of pH, contact time, concentration, and temperature on dye removal. The adsorption kinetics followed the pseudo-second-order (PSO) model, while the isotherm data best fitted the Freundlich model, indicating multilayer adsorption. The ZnAl@EC composite demonstrated superior adsorption capacity (243.902 mg/g at 40 °C) compared to ZnAl@LDH and EC. Thermodynamic studies revealed that the adsorption process was spontaneous and endothermic for ZnAl@LDH and EC but exothermic for ZnAl@EC. The regeneration study showed that ZnAl@EC retained significant adsorption capacity even after seven cycles, indicating its potential for practical applications in wastewater treatment.
