Abstract

FEBIAN SESARIANI, 2023, DETERMINATION OF FORMALIN LEVELS IN SALTED FISH IN THE JEBRES SUB-DISTRICT SURAKARTA AREA WITH SPECTROPHOTOMETRY UV-VIS METHOD, SCIENTIFIC PAPERS, THREE YEAR DIPLOMA IN PHARMACY, FACULTY OF PHARMACY, SETIA BUDI UNIVERSITY, SURAKARTA. Supervised by apt. Reslely Harjanti, S.Farm., M.Sc. Fish is a source of protein and an export commodity that are easily decayed compared to meat, fruit and vegetable products, so it is necessary to add preservatives so that the fish can last longer. The use of formalin as a preservative for salted fish is clearly prohibited according to PERMENKES No. 033 of 2012 concerning Additional Materials Food because it can cause cancer in humans. This study aims to determine the level of formalin in salted fish circulating in the District of Jebres Surakarta by spectrophotometry UV-Vis. Samples taken were 5 samples of salted fish taken from the Jebres District Market Surakarta. This study used 0,5% Chromatofat Acid reagent and schiff reagent for qualitative testing. Quantitative tests were carried out using the spectrophotometer UV-Vis 1800 shimadzu. The results of qualitative test of formalin content in 5 samples taken in the market area of Jebres Subdistrict Surakarta showed 3 positive samples containing formalin, marked with a purplish-red solution. The results of the quantitative test showed that the maximum wavelength value obtained was 587 nm with a linear regression equation y = 0,1017x + 0,3577. The level of sample A is 12,83 µg/mL ±0,14. The level of sample B is 20,25 µg/mL ±0,04. The level of sample C is 2,52 µg/mL ±0,18.
