Abstract

Composting is a waste management process that converts organic material into humus that can be reused. Composting can be applied using several methods such as the open windrow method, this method is a way of making compost that will get sufficient aeration so that it will help the compost maturity process more quickly. The aim of this research is to compare the results of composting using the open brick method and open windrow based on chemical parameters. During the composting process, a different bioactivator was added to each compost, using two bioactivators, namely MoL and M-Bio, and periodic checks were carried out every three days during the six weeks of composting. Based on the comparison results, the C, P content and C/N ratio in the two methods produced content values ​​that were not significantly different, however, in the overlay brick method, the control compost was superior in terms of P content and C/N ratio. Meanwhile, the open windrow method has a consistent increase in C, P content and C/N ratio.

Abstract

Wastewater treatment requires effective technologies for pollutant removal and sustainable water management. This study aimed to map the development of Continuous Electrocoagulation (CEC) research, identify research gaps and emerging themes, and synthesize operational and implementation issues. A Systematic Literature Network Analysis (SLNA) integrating Bibliometric Analysis (BA) and Qualitative Content Analysis (QCA) was applied to 99 Scopus-indexed journal articles published between 2019 and 2024. BA examined publication trends, collaboration networks, and research hotspots, while QCA synthesized evidence on Sustainable Development Goals (SDGs), operational factors, and implementation challenges. Publication output increased from 7 articles in 2019 to a peak of 22 in 2022, followed by 20 in 2023 and 14 in 2024. Thematic analysis indicated increasing attention to continuous operation, reactor configuration, pollutant removal, and energy efficiency. QCA showed that CEC research repeatedly examines electrode material, current density, pH, electrode distance, flow rate, electrolysis time, conductivity, temperature, supporting electrolytes, and hydraulic retention time. Key implementation challenges include electrode passivation, energy and electrode consumption, sludge management, effluent-quality control, and limited reactor standardization and scale-up evidence. Overall, CEC shows potential to support SDGs, while future research should prioritize multivariable optimization, pilot-scale validation, and sustainability assessment.
