Abstract

The global COVID-19 epidemic compelled all educational institutions, including universities, to cease academic instruction. To assure the ongoing process of teaching, learning, and assessment, several universities have transitioned from traditional face-to-face techniques to online ones. The purpose of the study was to examine the online-education experience in an Environmental Engineering course using a virtual lab and simulation software, as well as to determine the student's perception of the implementation of virtual labs and simulation software and the benefits of these tools for enhancing learning activities. To familiarize students with various areas of environmental engineering analysis, two simulated experiments were developed: water quality monitoring and adsorption spectroscopy. The virtual labs were generally well-received, as indicated by the responses to the Likert-type questions. Virtual laboratories are more acceptable for senior students than for first-year students, according to the consensus. 88% of respondents agreed with the average of twenty claims, compared with 3% who disagreed and 9% who agreed but disagreed with the statement. This illustrates that, although students believe that substituting virtual laboratories for conventional laboratories is not a complete solution, they believe that virtual laboratories can be used in conjunction with conventional methods to facilitate improved study outside of laboratory hours. Virtual and online learning in engineering labs are still relatively new; additional research is necessary before instructors can effectively utilize this delivery medium and its accompanying technologies to enhance student learning.

Abstract

Problem-based learning (PBL) is an effective educational approach that promotes critical thinking, collaboration, and creativity. The study aimed to review an implementation of PBL in engineering course in Malaysia. PBL has been shown to be effective in engaging students in the learning process by presenting them with complex, open-ended problems that require critical thinking and creativity to solve. Through this process, students develop their critical thinking skills, including their ability to analyze information, evaluate arguments, and make sound judgments. PBL also helps students to develop their problem-solving skills, which are essential in the real world. Despite its benefits, implementing PBL in the classroom can also have some challenges and limitations. It can be time-consuming, difficult to assess, challenging to implement in large classes, and may not be suitable for all students. Thus, careful planning and preparation are required before implementing PBL in a university setting. In an engineering course, PBL provides students with opportunities to develop their critical thinking and problem-solving skills, as well as to enhance their collaboration and communication abilities. It also allows students to see the relevance of the knowledge and skills they are learning and to take ownership of their learning. Therefore, implementing PBL in a university requires identifying appropriate learning objectives and designing a problem or scenario that aligns with those objectives. The problem or scenario should be complex and open-ended, requiring students to draw on knowledge and skills from multiple subject areas. The implementation of PBL should also involve ongoing evaluation and refinement to ensure its effectiveness.

Abstract

 Teaching environmental chemistry today involves both conventional and digital learning modes. Traditional approaches such as lectures, problem-solving, and laboratory exercises, offer content that is more or less structured with direct interaction, but not active engagement, interactivity, and enough resources are often found wanting. To better learn the subject, blended learning has been introduced, including some important digital tools like online facilities, simulations, and virtual labs. These ensure access and increase participation but the major con that students show low motivation because of the unequal access to the tools, the challenge that teachers face using the new tools, low student motivation, and problems in assessment. Its use has grown, but the effectiveness of blended learning, especially in stoichiometry and mass balance, which are considered to be rather complex, is not well documented. This review aimed to answer how traditional, digital, and blended learning approaches work in environmental chemistry education and what the benefits and challenges of each are. While traditional methods are more inclined to encourage the interaction of the instructor, which already appears to be passive and sometimes disconnected from the real situation outside the classroom, the blended learning method will put forward greater interactivity and personalization, though much will now depend on the individual student and the access to technology. A balanced approach will be evidenced by blended learning, with the strong points imbibed from both the modes, but, however, much intelligence is required to apply it to steer clear of further weaknesses. For improvement in the teaching of Environmental Chemistry, it is essential to invest in the digital infrastructure, faculty training, strategies of student engagement, and innovative models of assessment. If applied strategically, then blended learning can bridge effectively between theory and practice, making the teaching of Environmental Chemistry more engaging, inclusive, and outcome-based.

Abstract

While environmental engineering helps to solve major world challenges, it still struggles with diversity, equity and inclusion (DEI). This study seeks to understand the current progress of DEI in environmental engineering education at the university level and for professionals. It analyzes studies related to DEI to discover difficulties that hinder its integration and considers proposed solutions for promoting an inclusive environment. Some main obstacles are the low number of minorities, insufficient DEI information in courses and opposition to reform within institutions. Various promising ways such as making changes to the curriculum, inclusive teaching, student mentorship schemes, instructor development and community involvement are covered. Even so, these different approaches often miss proper support and coordination which reduces their usefulness over time. The review points out flaws in how assessment is done and suggests incorporating DEI concepts throughout education policies, teaching activities and professional life. In the end, it recommends ways that teachers, schools and policy groups can promote DEI by staying committed and joining forces.

Abstract

Clean water awareness through STEM (Science, Technology, Engineering, and Mathematics) activities has become increasingly relevant, especially in rural areas where issues like water pollution and limited access to clean water persist. This paper described an outreach program with the aim of boosting both STEM understanding and health awareness among primary school students in a rural Malaysian community. The sessions were conducted hands-on, involving simple experiments and water filtration demonstrations using readily available materials. These activities highlighted experiential and inclusive learning, aligning with the goals outlined in the Malaysia Education Blueprint 2013–2025. During the program, students explored the science behind water contamination and its health impacts, followed by building their basic water filters. Students responded well during quizzes and interactive tasks, which helped track their learning progress. Notably, their awareness of waterborne diseases and confidence in applying basic filtration methods increased significantly from 15% before the program to full participation and understanding afterwards. Besides gaining knowledge, the activities seemed to shift their attitudes. Many students started asking questions about their household water sources, showing a level of curiosity that was not there before. This kind of learning rooted in real-life context demonstrated that STEM outreach does teach science as well as allows young learners to care about their environment and health. The model used in this program has strong potential to be adapted for other communities where resources may be limited but the need for awareness is in need.

Abstract

Pekalongan, yang dikenal sebagai kota batik, mengalami peningkatan timbunan sampah harian dari 418.182 m³/hari menjadi 478.642 m³/hari pada tahun 2023, yang berpotensi memperbesar kontaminasi mikroplastik di perairan. Penelitian ini bertujuan untuk menganalisis sebaran dan kelimpahan mikroplastik pada permukaan air dan sedimen di kawasan muara hingga pesisir Sungai Loji, Pekalongan. Pengambilan sampel dilakukan secara in-situ di 11 stasiun, dengan mempertimbangkan kondisi pasang menuju surut dari hulu ke arah pesisir. Analisis kelimpahan dilakukan di laboratorium, sementara sebaran mikroplastik dimodelkan menggunakan pendekatan hidrodinamika dan particle tracking dua dimensi. Hasil menunjukkan kelimpahan mikroplastik pada air berkisar 6,9–28 partikel/m³ dan pada sedimen 587,5–682,5 partikel/kg, dengan bentuk fragment dan warna hitam mendominasi lebih dari 50% sampel. Konsentrasi tertinggi pada air ditemukan di area perairan terbuka, sedangkan pada sedimen terkonsentrasi di wilayah pesisir. Faktor-faktor seperti aktivitas antropogenik, debit sungai, angin, dan arus laut memengaruhi distribusi, sementara keberadaan jetty di pesisir memperkuat akumulasi partikel di dasar perairan. Pola distribusi divergen teridentifikasi melalui model hidrodinamika yang menggambarkan pengaruh arus pasang surut dan arus sejajar pantai.

Abstract

Pyrene is a very resistant polycyclic aromatic hydrocarbon (PAH) with four benzene rings that survives in the environment. This study was aimed at investigating the tolerance of earthworms in soil contaminated with pyrene. The studies were performed by employing earthworms gathered from shady regions adjacent to sewage ponds as pyrene degraders to eradicate pyrene from the soil. Numerous factors affecting pyrene degradation efficiency were explored, including the effect of contaminant concentration, earthworm and soil ration, and soil condition. The highest pyrene removal (31.2%) was shown by earthworms in the condition of soil mixed with cow dung. Pyrene decomposition was inhibited during soil sterilization due to the absence of soil microorganisms and indigenous pyrene-degrading bacteria. Nonetheless, earthworms are suitable for use as pyrene degraders in contaminated soil.

Abstract

The utilization of less expensive and more effective adsorbents derived from a variety of basic materials has been investigated. The research aimed to investigate the feasibility of employing waste paper as the adsorbent to remove the cresol red (CR) dye from wastewater through adsorption mechanism. Langmuir, Jovanovic, and Freundlich model were observed for isotherms models, while pseudo-first-order and pseudo-second-order were examined for kinetic models. The results indicated that increasing the adsorbent dose and contact time gave no significant effect to adsorption capacity while adsorption capacity increased with the increasing of pH until it reached a maximum at pH 8, and raising the starting dye concentration leads in a significant increase in adsorption capacity (16.7 mg/g). When the experimental adsorption isotherms and kinetic were fitted using the Freundlich models and pseudo-second-order model, it was discovered that those models were more accurately represented by the data, as indicated by a high correlation coefficient (R2) of 0.974 and 0.963.

Abstract

There are several environmental issues caused by economic growth and urbanization, such as soil degradation, water scarcity, deforestation, and biodiversity extinction. To solve these environmental problem issues, cleaner production (CP) had presented as account to reduce waste generation, energy usage and environmental pollution.CP concept was accepted and applied on many industrial sectors. Based on the current trend, CP is shifting to tackle global environmental problems by focusing on reducing carbon emission and resources consumption. In this paper, implementation of CP was presented such as waste and pollutants reduction, process and products efficiency improvements, and risk reduction towards human and environment. Overall, CP is an effective tool not only in environmental protection, but also in company management as it can increase the profit gains, reduce resources consumption, reduce pollutants emission and protects the safety of staff and workers.
