Abstract
This study aims to develop and validate a low-cost method based on TCS3200 color sensor and an Arduino Uno microcontroller with integrated development environment (IDE) software for the determination of tartrazine levels in children's snacks.The measurement results will be compared with the standard UV-Vis spectrophotometer method.Samples were prepared by heating and extracted using wool yarn, from which the attached samples were collected.The sampling technique was conducted on 6 types of snacks sold in Banda Aceh City.The analysis results showed that tartrazine levels ranged from 1.34 to 4.65 ppm using the TCS3200 color sensor, which were consistent with those obtained using UV-Vis spectrophotometer (1.32-4.64ppm).Linearity (R 2 ) and accuracy obtained in this study were 0.987 and 93.2 to 109% for the TCS3200 color sensor, and 0.988 and 93 to 115% for UV-Vis, respectively.The intraday and interday relative standard deviations (%RSD) did not exceed 2%.Based on the t-test calculation, it was shown that the measured tartrazine levels using the TCS3200 color sensor were not significantly different from those obtained using the UV-Vis spectrophotometer.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
