description: This study aims to synthesize carbon dots (C-dots) from papaya peel waste using microwave irradiation method and assess their potential as Fe³⁺ metal ion sensor.  The synthesis was carried out by smoothing papaya skin and heating it using microwave, then characterization was carried out using UV-Vis spectrophotometer and photoluminescence (PL). The results showed that the Cdots produced had a cyan-colored luminescence when illuminated by UV light, with emission peaks in the range of 420-490 nm. UV-Vis analysis showed a change in absorbance spectrum after the addition of Fe³⁺, while PL analysis showed a change in emission intensity indicating a specific interaction between Cdots and Fe³⁺ ions. Based on these results, C-dots from papaya skin have the potential as a sensitive and environmentally friendly optical sensor material to detect Fe³⁺ heavy metal.
