This study evaluates implementation of asynchronous learning in teaching engineering electromagnetics module. A group of first-year engineering students participated in the study. The instruction was divided into two periods, with the first period using asynchronous online mode and the second period using synchronous face-to-face mode. The performance evaluation was based on essay questions on class tests, and the data variances were statistically analysed. In addition, student feedback was gathered through interviews conducted at the end of the semester. In terms of overall performance, the results indicate that synchronous and asynchronous learning methods were equally effective, as no significant difference was found. However, individual student grades revealed a variety of outcomes for the asynchronous learning method, suggesting that students have different learning preferences and levels of adaptability. Positive feedback for asynchronous learning included the ability to adjust the pace of learning and conveniently access course materials. Students valued the availability of recorded lectures for reviewing difficult subject matter. Students with lower study motivation or limited experience with independent learning were negatively affected by the absence of scaffolding and immediate feedback in the asynchronous learning approach. Some students emphasized the importance of face-to-face interaction with the instructor, especially in a subject like electromagnetics that requires intuitive thought and elaboration.

The 2022 Programme for International Student Assessment (PISA) results depict a significant decline in the academic performance of Indonesian 15-year-olds in mathematics, reading, and science. The results position Indonesia's scores among the lowest since the country first participation in 2001. This editorial examines the implications of these results, drawing on data presented in PISA 2022, which illustrate the downward trend in performance and the widening gap between different socioeconomic groups. It argues for urgent educational reforms aimed at overhauling the current curricular frameworks, enhancing teacher training, and ensuring equitable educational opportunities. Specific strategies to achieve these goals include implementing the Merdeka Curriculum to promote student-centered learning, integrating educational neuroscience-based interventions to address learning disabilities, and leveraging intelligent tutoring systems and social media for collaborative learning. Additionally, developing localized assessments like the Indonesian Madrasah Competency Assessment and the Assessment of Indonesian Student Competence ensures alignment with international standards while addressing local needs. Through a comparative analysis with OECD averages and higher-performing nations, this piece highlights the necessity for Indonesia to adopt international best practices while tailoring them to local contexts. The ultimate goal is to equip Indonesian students with the skills necessary to meet both current and future challenges, thus improving their outcomes in subsequent PISA assessments and fostering national development. This article calls on policymakers, educational leaders, and stakeholders to engage in a concerted effort to address these educational deficiencies with the seriousness they deserve.

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan, keterampilan teknis, dan kemandirian masyarakat Desa Sekotong Barat dalam pengolahan air limbah melalui penerapan teknologi Membran Bioreaktor (MBR). Permasalahan utama mitra adalah pencemaran air akibat aktivitas penambangan emas tradisional, rendahnya kapasitas teknis masyarakat dalam pengolahan limbah, serta belum adanya model pengelolaan air olahan berbasis BUMDes. Metode pelaksanaan menggunakan pendekatan Participatory Technology Transfer melalui workshop, pelatihan, praktik langsung, pendampingan intensif, dan evaluasi partisipatif. Mitra kegiatan meliputi PKK Desa Sekotong Barat, BUMDes Gita Nada, pemerintah desa, Karang Taruna, mahasiswa KKN-PMM, dan masyarakat terdampak. Hasil kegiatan menunjukkan bahwa pelatihan dan pendampingan meningkatkan pengetahuan serta keterampilan teknis peserta. Sebelum kegiatan, sebagian besar peserta belum mengenal teknologi MBR, sedangkan setelah kegiatan seluruh peserta memahami konsep dan fungsi MBR, serta sebagian besar mampu mencoba atau mengoperasikan alat secara mandiri. Rata-rata skor kompetensi peserta meningkat dari 57,35 pada pre-test menjadi 85,45 pada post-test dan menunjukkan perbedaan yang bermakna secara statistik berdasarkan uji paired sample t-test yang dilaporkan pada bagian metode dan hasil. Pada aspek kualitas air, 15 dari 20 peserta mampu menghasilkan air olahan awal yang tampak lebih jernih berdasarkan indikator visual awal, yaitu warna, bau, kejernihan, dan berkurangnya partikel tersuspensi. Namun, evaluasi kualitas air pada kegiatan ini belum mengacu pada standar baku mutu air bersih karena belum dilakukan uji laboratorium terhadap parameter pH, TDS, kekeruhan, BOD/COD, merkuri/logam berat, dan mikrobiologi. Oleh karena itu, hasil air olahan belum dapat dinyatakan layak atau aman digunakan masyarakat sebelum pengujian lanjutan dilakukan. BUMDes menunjukkan kesiapan awal untuk mendukung keberlanjutan program, tetapi masih memerlukan penguatan SOP, operator, biaya operasional, mekanisme distribusi, dan legalitas. Kegiatan ini menunjukkan bahwa integrasi teknologi MBR, pelatihan partisipatif, pendampingan mahasiswa, dan penguatan kelembagaan desa berpotensi menjadi model awal pemberdayaan masyarakat berbasis teknologi tepat guna. Community Empowerment in Sekotong Barat through Membrane Bioreactor Technology for Wastewater Treatment into Clean Water Abstract This community service program aimed to improve the knowledge, technical skills, and self-reliance of the Sekotong Barat Village community in wastewater treatment through the application of Membrane Bioreactor (MBR) technology. The main problems faced by the community partners were water pollution caused by traditional gold mining activities, limited technical capacity in wastewater treatment, and the absence of a village-owned enterprise-based model for treated water management. The program employed a Participatory Technology Transfer approach through workshops, training, hands-on practice, intensive mentoring, and participatory evaluation. The partners involved included the PKK group of Sekotong Barat Village, BUMDes Gita Nada, the village government, youth organizations, KKN-PMM students, and affected community members. The results indicated that the training and mentoring improved participants’ knowledge and technical skills. Before the program, most participants were unfamiliar with MBR technology, whereas after the program all participants understood the concept and function of MBR, and most were able to try or operate the equipment independently. The average competency score increased from 57.35 in the pre-test to 85.45 in the post-test and showed a statistically meaningful difference based on the paired sample t-test reported in the methods and results sections. Regarding water quality, 15 out of 20 participants were able to produce preliminary treated water that appeared visually clearer based on the initial visual indicators, namely color, odor, clarity, and reduced suspended particles. However, the water quality evaluation in this program did not yet refer to clean water quality standards because laboratory testing of pH, TDS, turbidity, BOD/COD, mercury/heavy metals, and microbiological parameters had not been conducted. Therefore, the treated water cannot yet be declared suitable or safe for community use before further testing is performed. BUMDes demonstrated initial readiness to support program sustainability, but further strengthening is required in terms of SOPs, operators, operational costs, distribution mechanisms, and legality. This program indicates that the integration of MBR technology, participatory training, student mentoring, and village institutional strengthening has the potential to serve as an initial model of community empowerment based on appropriate technology.

Alignment of inquiry learning has embarked on remote inquiry as a replacement for face-to-face inquiry. On the other hand, the current technological developments bring opportunities to use it as a learning resource to support critical thinking. The current study explores the impact of virtual simulation-assisted remote inquiry in Fourier transform courses on prospective STEM teachers' (PST) critical thinking (CT) skills. The experimental design employed a randomized pretest-posttest control group was employed. Two groups of samples were randomized: the experimental group, n = 30, and the control group, n = 30. The treatment of learning was different in each group. The experimental group was conducted by virtual simulation-assisted remote inquiry, while the control group was conducted by online learning without inquiry and simulation. The measured CT skills aspects included analytical, inference, evaluation, and decision-making measured by an essay test instrument. The results were then analyzed descriptively and statistically. The results confirm that the virtual simulation-assisted remote inquiry significantly improved PST CT in Fourier transform courses. The virtual simulation-assisted remote inquiry learning was better than courses with online learning without inquiry and simulation. The virtual simulation-assisted remote inquiry provided conceptual formation and application of concepts. It strengthened the opportunities for the PSTs to train their CT skills.

The reliability of pedagogical practice is highly dictated by how it enhances science, technology, engineering, and mathematics (STEM) students’ critical thinking achievement. Adequate pedagogical practice is thus needed in line with the demands of STEM learning in the 21st century, namely achieving optimal critical thinking. This paper reports this pedagogical practice on a topic of polymer film fabrication irradiated with gamma rays. The specific objective was to analyze STEM students’ critical thinking performance in literacy of the aforementioned topic. It is an exploratory study with an experimental method. Only one treatment group was involved, they were STEM students attending the Material Physics Courses. By employing valid critical thinking instruments and adequate methods of analysis, the findings show that literacy on the assigned topic significantly improved STEM students’ CT skills. It was proven that the mean scores of CT indicators have increased in all aspects of the CT assessed. The statistical analysis confirmed that there were significant differences in the CT skills of STEM students between the observations before and after the learning process intervention. The implication of this study is that pedagogical interventions integrated with studies on advanced material modification technology could be effectively used for creating inspiring STEM learning, especially for training STEM students’ critical thinking ways.

As the forefront in fiber materials development, electrospunÂ nanofiber membrane (NFM)Â is potentially reliable for wastewater treatment due to its excellent properties for instance; large surface area,Â high porosity, tuneableÂ pore size, and has great flux as compared to other conventional membranes. However, fouling issue will lead to degradation of membrane performance. Fouling issue can be alleviated by applying membrane surface modification. In this study, thermal annealing is applied onto nylon 6,6 nanofiber membrane with three different temperatures (60Â°C, 80Â°C and 120Â°C). Results show that annealing causes membrane shrinkage and reduction of membrane fiber diameter where the fiber reduced from 138.5 nm to 108.5 nm when annealed at 120Â°C. The optimum annealing temperature for the membrane was found to be at 60ËšC as the membrane shows the highest flux at 1200 L/m2.h at 75 minutes filtration time and took longer time to get fouled (>75 minutes) compared with un-annealed membrane (55 minutes). Nylon 6,6 nanofiber membrane is also proven to give more than 90% of COD and turbidity rejection.
