Mini UV And Mini GC Workshop Enhances Chemistry Teachers’ Competence In Instrumental Analysis
Semarang, June 11, 2025 — In an effort to enhance chemistry teachers’ competence in chemical analysis, the Chemistry Department of the Faculty of Mathematics and Natural Sciences (FMIPA), Universitas Negeri Semarang (UNNES), organized a workshop on the use of Fluorescence/UV-Vis Spectrophotometer and mini Gas Chromatography (GC) for chemistry teachers.
This activity, which is part of a community service program, was attended by 20 chemistry teachers. The workshop aimed to introduce modern, portable, and practical analytical instruments to support their application in school-based learning.
In his presentation, the speaker, Muhammad Alauhdin, explained that, in principle, mini UV and mini GC instruments perform similarly to bench-top versions of UV-Vis spectrophotometers and GC systems. However, the mini versions are designed for faster, more practical, and portable analysis, making them highly suitable for classroom applications and for introducing modern analytical techniques at the school level.
The speaker demonstrated the operation of the Mini GC and Mini UV Spectrophotometer.
During the workshop, participants were given direct demonstrations of measurement procedures using both instruments. They showed strong enthusiasm throughout the sessions, from theoretical explanations to hands-on practice.
Interactive discussions and Q&A sessions were active, particularly on how these instruments can be applied in high school chemistry teaching and in preparing students for scientific competitions. The teachers expressed great interest in integrating this technology into their teaching practices.
