The students worked on a variety of subjects, ranging from clinical testing to designing control systems using hardware programming languages.
The ACA group (A. R. Kalalo, C. A. Widodo, and A. Khoris) was recognized for their sense of intergenerational equity and advocacy to reduce waste pollution. The group presented their mechanical design that collects waste material in the water.
In this group, Arkana Richie used a microcontroller board along with several sensors and actuators, and successfully displayed the automatic sorting of organic and inorganic trash.
The project highlights the importance of sustainability and the need for more environmentally conscious solutions. Equally interesting is the oil extraction through steam distillation presented by D. G. Kwee, F. A. S. Tobing, and G. D. Widjaja.
They introduced how essential oils are extracted from plants, showing how their method was cost-effective, easy to operate, and could be easily integrated into any existing production processes. Achieving third place, Harry Chiu demonstrated how his gas detector design, using Arduino system, can detect the presence of gas and trigger an alarm system in case of gas leaks.
