The Biology Teachers’ Association (MGMP) of East Java Province, in collaboration with the Faculty of Biology, Universitas Gadjah Mada, successfully organized a laboratory-based teacher competency enhancement program through a practicum entitled “Chromosome Studies in the Cell Cycle through a Cytogenetic Approach” on Monday, June 15, 2026, from 09.00–12.00 WIB at the Genetics and Breeding Laboratory, Faculty of Biology, UGM. The activity, attended by 35 biology teachers from Madrasah Aliyah (MA), provided a research-based and hands-on laboratory learning experience that enabled participants to gain a deeper understanding of cytogenetics, the cell cycle, and plant chromosome analysis through direct practice and microscopic observation.
The program began with opening remarks delivered by the Head of the Genetics and Breeding Laboratory, Ganies Riza Aristya, S.Si., M.Sc., Ph.D. In her remarks, she emphasized the importance of research-oriented biology education and laboratory experimentation as an effort to improve the quality of science education that is contextual, innovative, and oriented toward the development of scientific skills.
The first session focused on chromosome preparation practicum using shallot roots as the object for mitotic observation. The practicum was guided by instructor Denianto Agung Wicaksono, S.Si., together with laboratory assistants. During this session, participants conducted direct laboratory practice starting from root cutting, fixation treatment, maceration, chromosome staining using aceto-orcein, squash techniques, and microscopic observation of chromosome preparations. Through this hands-on laboratory approach, participants gained practical experience in observing cell division stages and understanding the fundamental principles of plant cytogenetic preparation.
During the microscopic observation session, participants successfully identified various stages of mitosis, including prophase, prometaphase, metaphase, anaphase, and telophase in shallot root meristem cells. In addition to strengthening participants’ understanding of cell cycle dynamics, the activity also introduced cytogenetic methods commonly applied in genetics and plant breeding research.
The second session continued with demonstrations and hands-on practice in constructing chromosome karyotypes and idiograms, guided by instructor Tiara Putria Judith, S.Si., together with laboratory assistants. Participants were introduced to chromosome analysis techniques using ImageRaster software, including calibration, chromosome arm length measurement, centromere position identification, chromosome morphology analysis, and idiogram construction as a visual representation of chromosome characteristics. This session provided practical insight into quantitative and systematic chromosome analysis approaches widely applied in modern cytogenetic studies.
The practicum activity “Chromosome Studies in the Cell Cycle through a Cytogenetic Approach” also contributed to the achievement of the Sustainable Development Goals (SDGs), particularly SDG 4 (Quality Education) through strengthening research- and practicum-based education, SDG 9 (Industry, Innovation and Infrastructure) through the development of laboratory and research competencies, SDG 15 (Life on Land) through increasing understanding of plant genetic diversity and characteristics, and SDG 17 (Partnerships for the Goals) through strengthening academic collaboration between higher education institutions and the Biology Teachers’ Association (MGMP) of East Java Province.
