Abstract

Industrial water consumption will account for 22% of global water demand by 2030. Industry water conservation is encouraged by rapid corporate growth. Industrial resource usage and pollutant emissions can be reduced via cleaner production methods. Recycling is essential to greener production and the circular economy. Recycling is crucial to achieving the 2030 Sustainable Development Goals. The electric vehicle (EV) sector has propelled battery business growth in recent years, especially in Indonesia. The electric vehicle (EV) sector will benefit from using Nickel Manganese Cobalt (NMC) batteries. The study will use reverse osmosis (RO) membrane filtration to recover water from recovered NMC battery effluent. The experiment will investigate feed solution concentrations, pressures (8, 10, and 12 bar), and temperatures (30, 40, and 50°C). Two factors—permeate flux and metal ion rejection—determine reverse osmosis membrane efficiency. Li and Na metal rejection was maximum at 30°C and 12 bar, with 94-96% and 90-93% rejection rates, respectively. Under certain operating conditions, reverse osmosis membrane technology significantly reduced sodium (Na) concentration in NMC battery recycling effluent. Thus, wastewater is no longer saline. Reverse osmosis water can be reused for cooling due to its Li and Na concentrations.

Abstract

Water management is one of the most challenging aspects of campus management. With a large number on campus population and limited water resources, water management is essential for achieving a resilient and healthy campus. In this paper, we explain two targets in UGM water management: water efficiency and water conservation. Both objectives are significantly related; however, each goal has a different approach to the method for the design approach and strategies in the implementations. Water efficiency is included in building new buildings and retrofitting the existing ones. Meanwhile, water conservation is implemented to calculate potential alternative water resources in UGM, including water treatment, to produce freshwater as an additional water supply. We also explain how water management is implemented in UGM from the highest Directorate to the lowest units. Through our method and best practices in UGM, we hope our paper could be a reference for other universities who want to implement a water management program.

Abstract

Rare earth elements (REEs) are chemical elements in the III B and lanthanide groups on the chemical periodic table. Extracting REEs from secondary resources (such as coal fly ash) could be environmentally friendlier than extracting REEs from primary resources. Coal fly ash was chosen because of its attractive REE availability and to minimize the pollution problem created by coal fly ash dumping. Citric acid is used as the leaching agent because of its biodegradability, relatively safe vis-à-vis mineral acid commonly used in the REE leaching, and its non-damaging nature to coal fly ash’s properties as construction material. The leaching experiment was conducted at temperature variations of 30, 50, and 85 °C, with liquid-solid ratio (L/S) of 5, 10, and 15 mL/g in 50 mL of 0.01 mol/L citric acid solution. The leaching experiments were conducted in a water bath shaker. It was found that increasing L/S and temperature mainly contributed to increasing cerium leaching capacity.

Abstract

Assessing sugarcane quality is crucial for ensuring both economic value and processing efficiency in sugar production. Conventional approaches, such as refractometer-based Brix measurements, are destructive, labor-intensive, and unsuitable for large-scale or rapid field evaluations. This study proposes a non-destructive deep learning framework for classifying sugarcane internodes into two quality categories (< 16 °Bx and ≥16 °Bx) to address existing limitations. Two convolutional neural network architectures, VGG19 and ResNet50, were evaluated utilizing a defined transfer learning and data augmentation methodology. Because of its residual connections, which enable deeper and more stable feature learning, ResNet50 consistently outperformed VGG19, achieving the highest accuracy of 78.85% on the Luar2_Putih dataset. This comparative finding demonstrates that modern residual-based networks provide superior robustness for subtle visual classification tasks in agricultural imaging, while also validating the stability of the proposed two-phase training framework. The study advances AI-driven non-destructive quality assessment by offering a scalable, field-deployable solution that supports sustainable, efficient sugarcane processing in line with the UN Sustainable Development Goals (SDG 2, 9, 12, and 13).

Abstract

Red mud merupakan residu dari proses Bayer dengan pH sangat tinggi (11–13) yang berpotensi menimbulkan pencemaran lingkungan. Meskipun demikian, red mud mengandung logam bernilai seperti Fe, Ti, dan unsur tanah jarang (REE), sehingga berpeluang dimanfaatkan melalui fitomining. Penelitian ini mengkaji kemampuan tanaman Vetiver (Chrysopogon zizanioides) dalam mengakumulasi logam serta memperbaiki kualitas media melalui fitoremediasi. Metodologi Response Surface Methodology (RSM) menggunakan Design Expert diterapkan untuk menganalisis pengaruh asam fosfat, asam humat, dan pupuk NPK Mutiara 16-16-16 terhadap respons utama yaitu penurunan pH red mud. Berdasarkan hasil percobaan, penurunan pH berlangsung efektif hingga berada pada rentang 6,5 – 6,8, sehingga kondisi media lebih mendukung pertumbuhan akar dan ketersediaan logam bagi tanaman. Vetiver menunjukkan pertumbuhan stabil pada media yang telah diberi perlakuan dan mampu mengakumulasi logam terutama pada bagian akar. Oleh karena itu, sistem fitoremediasi–fitomining berbasis Vetiver berpotensi diterapkan sebagai solusi pengelolaan red mud yang lebih ramah lingkungan.
