Bandung, March 5, 2025 – The Chemistry Learning and Teaching Research Laboratory (LPBM) of FPMIPA UPI felt more colorful than usual. A warm and enthusiastic atmosphere colored the workshop themed “Introduction to the Application of Chemicals in Daily Life through Making Tie Dye Batik”. This activity not only introduced the friendly side of chemistry to participants, but also became a moment to strengthen friendship between students from two countries: Japan and Indonesia.
The workshop was guided by Adinda Melinda Ceria Ajie, a Masters student of Chemistry Education UPI, who enthusiastically explained various types of dyes, from natural to synthetic. One of the materials used in the practical session was naphthol dye, which was then applied in the process of making tie dye pattern t-shirts. A total of 9 students from Chiba University, accompanied by Prof. Jun Nomura, joined 3 UPI students and 2 ITB students to participate in the activities held after the Guest Lecture and Cultural Exchange events. They were also accompanied by several UPI Chemistry Education lecturers who supported the event.
One of the most exciting highlights of this event was the practice session of making their own tie dye t-shirts. The participants showed their creativity through various patterns such as binding, bull eyes, swirl, and knotting. Interestingly, male students tended to choose the swirl pattern which was considered dynamic and simple, while female participants were more diverse in choosing motifs, showing a broader exploration in creativity.
Laughter, discussion, and admiration were heard throughout the event, especially when the participants saw the final results of their own tie dye t-shirts. “Wow, it turns out I can make something like this too!” said one of the students with sparkling eyes. More than just an art workshop, this event carries an important message: that chemistry is not always synonymous with danger, but can also be a bridge of understanding across cultures and fields. Through this event, participants are invited to see how chemicals are used safely and usefully in everyday life.
It is hoped that activities like this can provide positive insight for the general public, both nationally and internationally, that chemistry has a very close place in life, and can even connect hearts across countries – from hearts to hearts, through science and art. (amca)
