This study aimed to analyze the Rhodamine B content in the terasi sold at the Pasar Belik, Pemalang Regency. The study was conducted in a descriptive observational manner where the sample was analyzed qualitatively and if the result were positive it would be followed by quantitative. The study was conducted in December 2020. Rhodamine B content in tersi was analyzed by univariate test. Qualitative analysis was carried out by chemical methods using 10% NaOH, Petroleum Eter and 10% HCl. The results of the qualitative analysis of 7 samples of shrimp paste sold at the Belik Market in Pemalang Regency were all negative and did not contain Rhodamine B. Shrimp samples that were bought and sold at the Pasar Belik in Pemalang Regency showed that they were free from Rhodamine B Keywords: rhodamine B, shrimp paste, qualitative analysis, food additives
