Abstract

Water pollution contributes to water crises at the global level by reducing the quantity and quality of freshwater resources available to humans and ecosystems. Agricultural wastewater can contain chemicals such as pesticides, herbicides, fertilizers, and organic matter. If discharged without treatment, it can contaminate water sources such as rivers, lakes, and groundwater. This study aims to optimize operating parameters in the form of voltage, electrocoagulation time, and calcium concentration to maximize the removal rate of nitrogen compounds in agricultural wastewater. This study used response surface methodology (RSM) to optimize the operational conditions of electrocoagulation and achieve a high level of allowance without the need for additional coagulants from outside. The results showed that the lowest nitrate concentration was 2.960 mg/L (an 88.37% reduction from the initial concentration) under the conditions of 45 V voltage, 15 minutes of electrocoagulation time, and a calcium concentration of 7 mg/L.. The lowest ammonia concentration was 0.016 mg/L (99.37%) at variations in voltage, electrocoagulation time, and calcium concentration of 30 V, 1.5 minutes, and 4.5 mg/L, respectively. The addition of calcium can react with ions produced from the anode to form coagulants, such as calcium hydroxide, which helps remove nitrogen compounds. The optimal operating conditions for EC to set aside nitrate and ammonia concentrations of 3.709 mg/L and 1.338 mg/L, respectively, are 45 V, 15 minutes, and calcium concentrations are 5.09 mg/L.  Agricultural wastewater treatment using EC succeeded in removing iron up to 96.73% of the initial concentration. The magnesium concentration is very low at 0.001 mg/L

Abstract

Larangan District is one of the shallot-producing areas that the government prioritizes for agricultural intensification. The high intensity of agriculture in Larangan District causes soil fertility and sustainability disparities. This research evaluates soil fertility and the sustainability of shallot farming intensification activities in Larangan District, Brebes Regency. Soil fertility evaluation used two different approaches: Base Cation Saturation Ratio (BCSR), which referred to Koppitke & Menzies research in 2007 and assessment through a combination of soil chemical properties, as referred to Soil Research Center of Indonesia. Sustainability analysis was carried out using the Rapid Appraisal for Farming (RAP-Farm) approach with a multi-aspect sustainability analysis method, with a total of 6 aspects (ecological, economic, social, institutional, technological, and logistics, and infrastructure) with 36 factors. The results of the research show that Larangan District has a moderate soil fertility status, with a nutrient unbalance from cation ratio analysis. Sustainability status shows a less sustainable status with aspects that have values below the limit, namely ecology, economics, and technology.

Abstract

Microplastics (MPs) have been globally detected in aquatic environments. The abundance of MPs contributed to the negative effects on aquatic ecosystems. Thus, it’s critical to create effective solutions for removing MPs from water. In this review, we compared several methods, including physical, physicochemical, and biological approaches, towards membrane filtration. The physical filtration technology is the simplest way in comparison with other methods. However, the removal ability of physical filtration against smaller MPs than 20 ????m becomes a crucial concern. Then, the other option is an adsorption method. Although the adsorption option is an inexpensive method, the undesirable aspect during adsorbent usage may not be environmentally friendly in aquatic systems. The similar problem is also demonstrated by chemical approaches in terms of coagulation and electrocoagulation treatment. Consequently, the biological methods were found to be less toxic to the environment. Even though it provides safe conditions to the environment, the biological approach needs a long time to degrade MPs. To overcome their disadvantages, the membrane technology offers efficient removal of MPs and no addition of chemical usage. However, the main point to pay attention to is that each technology has benefits and drawbacks. Therefore, the application of multiple technologies for MPs removal is considered.

Abstract

Tofu liquid waste produced by the tofu industry in rural areas is often not reprocessed and has the potential to cause pollution if left untreated, so it is necessary to utilize tofu liquid waste which is the main idea in this research. The aim of this research is to analyze the potential for utilizing tofu liquid waste into fish supplements through the fermentation process with EM4 and Nitrobacter Plus and analyzing the economic and environmental benefits of utilizing tofu liquid waste into fish supplements. This research was conducted using an experimental method using a Completely Randomized Design (CRD) with 4 treatments and 3 replications. This research result showed that the provision of fish supplements from fermented tofu liquid waste has no significant effect on absolute weight growth, absolute length growth, specific growth rate, feed conversion ratio and survival rate. Based on the results of the economic analysis, the utilization of tofu liquid waste as a fish supplement was considered economically feasible with a Benefit Cost Ratio (BCR) of 1.285, Net Present Value (NPV) of Rp. 16,320,630,763 and Return on Investment (ROI) of 48.4%.

Abstract

Ministry of Forestry has designated Kreo Sub-watershed, part of Garang Watershed, a critical area due to high erosion rates contributing to flooding in Semarang. Rapid land use changes accelerate environmental degradation, increasing erosion and sedimentation risks. This study measures erosion and sedimentation rates in Kreo Sub-watershed using SWAT (Soil and Water Assessment Tool), determines Erosion Hazard Index, and proposes erosion control solutions based on Land Rehabilitation and Soil Conservation Analysis (ARLKT) with vegetative conservation. ARLKT approach includes simulating new land use scenarios to assess their impact on erosion reduction. To ensure SWAT modelling accurately represents field conditions and not overestimate—allowing conservation recommendations based on ARLKT applied appropriately—a field-based sedimentation analysis also conducted. The study utilizes rainfall, soil type, slope, and land use data in 2019 and 2024 from satellite imagery and validated using a confusion matrix. Results indicate a shift in Erosion Hazard Index from predominantly ‘Moderate’ in 2019 to ‘High’ in 2024, underscoring urgent need for sustainable watershed management. By integrating remote sensing, field validation, and hydrological modeling, this study offers a precise, data-driven approach to erosion control. The findings serve critical reference for policymakers in developing effective conservation strategies to enhance watershed resilience.

Abstract

Non-revenue water (NRW) is a significant issue for water supply in Indonesia, with a national NRW rate of 33.7% in 2022 and even higher at PT Air Minum Giri Menang (PT AMGM) at 36.21%. Although District Metered Areas (DMA) were implemented in 2018, their effectiveness has been limited due to poor monitoring. This study evaluates the current DMA conditions by creating a water balance and using EPANET 2.2 software for analysis, along with formulating optimization strategies through technical, financial, and institutional assessments. The research identifies fifteen DMAs, with five being well-established. Two DMAs were chosen for optimization. Simulations showed that many pipes in these DMAs did not meet flow speed standards. Water pressure in DMA Graha Permata Kota was fully satisfied at 100%, while DMA Elit Kota Mataram achieved 84.5%. The study noted a significant NRW reduction by an average of 27.26% in the selected DMAs. The total repair cost was Rp 14,725,300, leading to additional annual revenue of Rp 128,747,424 and a positive feasibility analysis. Institutional performance was rated as "good," but an increase of 14 field staff for water loss control is needed.

Abstract

Environmental pollution from wastewater and soil contamination remains a critical global concern, with current treatment methods often facing limitations in scalability, cost, or environmental safety. Biochar, a carbon-rich material derived from biomass pyrolysis, has emerged as a sustainable adsorbent for heavy metals and organic pollutants. While its use in environmental remediation is well-established, the fate and reuse of spent biochar have received limited attention. This comprehensive review explores the untapped potential of used biochar, particularly for the removal of hexavalent chromium (Cr(VI)) from wastewater and its role in enhancing soil fertility. We critically analyze current practices, mechanisms of Cr(VI) removal using spent biochar, regeneration techniques, and field applications, while highlighting circular economy frameworks that promote resource efficiency. The study integrates empirical evidence from recent case studies and offers policy recommendations to support large-scale implementation. This work is the first to provide an integrative review of the reuse of spent biochar with a dual focus on wastewater treatment and soil enhancement, underpinned by a circular economy perspective. It addresses critical research gaps by evaluating regeneration techniques, post-use functionality, and practical field applications, thereby positioning spent biochar as a viable, low-cost, and eco-friendly alternative in environmental management systems.
