“Care for the environment is not just words but real actions”

Waste is a serious problem in developing countries. Indonesia National Plastic Action (NPAP) reports that around 70% or around 4.8 million tons of plastic waste is not managed, causing environmental pollution. So, wise steps are needed in utilizing plastic waste into products of higher value.

On the other hand, it is known that it is very important to use coasters when consuming drinks. Cold drinks are often foggy and look wet, so water vapor in the form of gas will experience a change in substance (condensation). That’s what causes water to splatter around the glass area if you don’t use a coaster and it dries out in a short time.

Therefore, the student group created an innovative coaster product made from plastic waste and diatomite so that it has a high absorption capacity. High Absorption Power, Exclusive Design, and Proven Effectiveness of Rupawan products gives the impression of an attractive design coated with diatomite. This advantage provides opportunities and benefits for its users. Thus, Rupawan coaster products contribute to solving the challenges of coaster problems in general through testing the use of product effectiveness.

The team behind Rupawan consists of Avina Dian Pratiwi, Senifa Azzahra, and Atilla Radja Satria under the guidance of lecturer Ir. Narulita Santi, S.T., M.Eng. This research received funding support from the Directorate General of Higher Education, Ministry of Education and Culture for the 5 Sector Student Creativity Program (PKM), 2024.
