Abstract

This paper critically examines the emerging trends, content evolution, and pedagogical innovations in materials engineering education. Using a systematic literature review approach, this study synthesizes key developments in materials engineering education focusing on enrolment trends in materials-related engineering disciplines and their implications for future research and educational practices. The result shows that the rapid technological, environmental, and industrial transformations of the 21st century have redefined the competencies required of materials engineers. As global challenges such as climate change, resource scarcity, digitalization, and sustainable development become more pressing, materials engineering education must undergo significant pedagogical and curricular reform to remain relevant. The findings aim to provide actionable insights for educators, policymakers, and curriculum developers in creating a responsive and sustainable materials engineering education system for the 21st century.

Abstract

This study aims to investigate how Environmental Chemistry education contributes to shaping the science teacher identity of prospective chemistry teachers through a STEM approach. The bibliometric analysis method was conducted using Scopus data (2015–2024), analyzed with Biblioshiny and VOS Viewer. From an initial 483 documents, 418 relevant works comprising articles, books, and reviews were selected based on keywords such as "Science Identity", "Science Teacher Identity", "STEM Education Approach", and "Environmental Science Chemistry". Biblioshiny was used to identify trends over the decade, including annual publication rates, key journals, influential authors, productive affiliations and countries, globally cited articles, and frequently occurring keywords. VOS Viewer further enhanced the analysis by offering three types of visualizations network, overlay, and density to illustrate the relationships and research trends among the selected publications. These visual tools reveal the interconnectedness of topics and highlight emerging areas in the field. The findings offer valuable insights into the global development of research at the intersection of science identity, STEM education, and environmental chemistry. This bibliometric exploration provides a foundation for researchers to identify current trends, understand the research landscape, and recognize gaps that can inform future studies.

Abstract

Pelatihan pembuatan sabun ini bertujuan untuk memberdayakan masyarakat, terutama kelompok PKK, dengan memberikan keterampilan membuat sabun yang dapat dikembangkan menjadi usaha rumahan. Pelatihan difokuskan pada praktek pembuatan sabun serta pengukuran peningkatan pemahaman peserta melalui pretest dan posttest dengan angket berskala Likert. Selain pelatihan teknis, analisis ekonomi untuk melihat apakah usaha ini layak dijalankan juga dilakukan. Analisis ekonomi menghitung Gross Profit Margin (GPM), Break-Even Point (BEP), Return on Investment (ROI), dan Internal Rate of Return (IRR) berdasarkan data biaya dan potensi penjualan. Dari sisi pengetahuan, hasil penelitian menunjukkan adanya peningkatan pengetahuan yang signifikan, dengan skor rata-rata naik dari 38/100 menjadi 82/100. Dari sisi ekonomi, usaha sabun ini dinilai sangat layak karena modal awal yang kecil, keuntungan tinggi, dan pengembalian modal yang cepat. Program ini tidak hanya meningkatkan keterampilan masyarakat, tetapi juga membuka peluang usaha berkelanjutan yang mendukung pemberdayaan perempuan dan pertumbuhan ekonomi lokal.. Strengthening the Capacity of PKK Members through Soap Production Training and Economic Value-Added Analysis This soap making training aims to empower the community, especially the PKK group, by providing soap making skills that can be developed into a home business. The training focused on the practice of making soap and measuring the increase in participants' understanding through pretest and posttest with Likert scale questionnaires. Apart from technical training, an economic analysis to see whether this business is feasible is also carried out. Economic analysis calculates Gross Profit Margin (GPM), Break-Even Point (BEP), Return on Investment (ROI), and Internal Rate of Return (IRR) based on cost data and potential sales. In terms of knowledge, the research results show a significant increase in knowledge, with the average score increasing from 38/100 to 82/100. From an economic perspective, this soap business is considered very feasible because of the small initial capital, high profits and fast return on capital. This program not only improves community skills, but also opens up sustainable business opportunities that support women's empowerment and local economic growth.

Abstract

This study investigates the corrosion resistance, surface hardness, morphological structure, and predicted lifetime of carbon steel coated with pure zinc (Zn) and zinc aluminum alloy (ZnAl) in chloride rich environments. Coatings were applied by hot dip galvanizing, and characterized using Field Emission Scanning Electron Microscopy Energy Dispersive X-ray Spectroscopy (FESEM-EDS), Vickers hardness testing, and salt spray testing. Before exposure, both coatings confirmed homogeneity with smooth, topographically uniform surfaces, and no macroscopic defects. ZnAl coatings also delivered superior hardness compared to pure Zn and uncoated steel. After exposure, ZnAl maintained smoother, more stable surfaces with smaller and fewer pitting defects, whereas pure Zn suffered medium to severe damage. Pure Zn coatings showed fluctuating corrosion behavior with an average rate of 7.8944 µm/year, while ZnAl coatings exhibited minimal fluctuations within ±0.1 µm/year, indicating high resistance to chloride concentration. Predicted lifetime ranged from 3.7 to 5.5 years for pure Zn (average 4.7 years) and 5.9 to 6.5 years for ZnAl (average 6.2 years). Despite being thinner, ZnAl provided superior corrosion protection and structural stability. These findings indicate that ZnAl alloy coatings provide superior corrosion protection, structural stability, and mechanical performance for carbon steel in chloride rich environments.
