Tartrazin dye code E 102 is a sy nthetic dye \vhich is lemon yello\\. Tartrazin is widely used because of its high stabilit} in light. oxygen. heat. pH, and relati\ely lo-wer costs. Tartrazine is a dye that is pem1itted by the drug and food control agenc} (BPOM) with maximum le\:els in drinks and food 70 mg I kg. The impact of consuming excess tartrazine causes allergies. itching. migraines and blurred vision. Tartrazine analysis in foods u sing molecularly tartrazine­ printcd polymer sorbents (tartrazine-IP) is more selective and more accurate than conventional analysi s. MIPs ha\e been successfully synthesi zed using methacrylic acid monomer (MAA). tartrazine as a template. trimetilol­ propanan Trimetakrilat (TRIM) as a crosslinker. Benzoyl peroxide (BPO) as the initiator. and dimethy I formamide as porogen. The resulting MIP \\aS characterized using fTIR.TGA. and SEM. The results of FTIR MIP and NIP produced peaks \'-ith \\ave numbers 1150.11 cm•1 • 1731.44 cm-1 • 2967.16 cm- 1 and 3479.58 cm-1 • \\ hich showed flexural C-R C = 0 carboxylic. C-H strain and 0-H. respectively. The analysis of TGA. MIP and NIP shows that at a temperature of 300 °C the mass decreases. SEM results show the surface morphology of MIP is smoother and the pore shape i s more regular than NIP. The MJP adsorption parameter evaluation \\ith batch method showed optimal at pH 3, contact time 60 minutes. adsorption capacity 13.01 mg I g, \\ith recovery around I 00%. adsorption behavior followed second-order kinetics and Langmuir isotherm. The resulting polymer is more selecti\e with S> 1. The results of the study showed that crackers san1ples sold in a store in Bandung cit} contained 0.42 mg I g or equal to 420 mg I kg v.ith recovery 95.47°/o.
