Formalin Detectors inside Fish UNAIR Teams Win AISEEF Gold 2021

The innovation was coming from five students from Universitas Airlangga (Unair). Two of them are from Physics. They are Firman Hidayat and Nabila Alvin Nadhiro . They made a design of formaldehyde detectors in fish successfully won gold medals in the 2021 Asean Innovative Science Environmental and Entrepreneur Fair (AISEEF) competition organized by the Indonesian Young Scientist Association (IYSA).

Formalin addition to foods to extend preservation is dangerous. Formalin is a common aqueous solution form of Formaldehyde (systematic name methanal) is a naturally occurring organic compound with the formula CH2O (H−CHO). In view of its widespread use, toxicity, and volatility, formaldehyde poses a significant danger to human health.

The design of formalin early detection in fish is made based on fiber optic sensors. This tool is to prevent and overcome fish problems using formalin which is widely circulated in the community. The design was successfully awarded an award in the innovative science category.

Furthermore, Firman said that the number of participants in the AISEEF 2021 competition reached 450 participants and came from 20 different countries. He also explained that there were many aspects that were assessed in the competition, including submitting abstract assessments, posters, video presentations, extended abstracts, to Q&A (question and answer) sessions.
