    PENGARUH KONSENTRASI FORMALIN PADA TAHU TERHADAP RESPON TEGANGAN KELUARAN PADA SENSOR GAS SEMIKONDUKTOR BERBASIS ELECTRONIC NOSE
    (Elfitra, 2023-10) Falencia, Ega Hadisty; Setiadi, Rahmondia Nanda
    Formaldehyde is widely used as a food additive to preserve food, one of which is tofu, because tofu has a high-water content which makes tofu rot quickly and taste sour. The use of formaldehyde as a preservative is strictly prohibited in accordance with the Republic of Indonesia Minister of Health Regulation No. 033 of 2012 because formaldehyde is dangerous for body health. One innovative technology that can be used to detect the presence of formaldehyde in tofu in a simple and practical way is system design Electronic Nose (E-Nose). The objective of in this research is tofu soaked with varying formaldehyde concentrations of 0%, 1%, 2%, 3%, 4% and 5% will be detected using a system E-Nose which is designed to use 3 gas sensors made from semiconductors, including the TGS2600, TGS2602, and TGS2611 gas sensors. The gas sensors used will produce a response in the form of an output voltage. From the voltage response produced by each sensor, if the greater the formaldehyde concentration is detected, the resulting voltage response will also increase.
