English is an international language used by many people in various countries. The ability to use English well can open up international standard educational and employment opportunities, because all companies need employees with a certain level of English skills to reach top positions. Currently there is a phenomenon of people who like to mix Indonesian and English in everyday conversations. This happens because it is influenced by the environment, society, education and trends. People who usually speak one language and then switch to another language, either at the beginning, in the middle or at the end of their speech, are called Bilingual. This research aims to identify the most common types of code switching used by Cinta Laura when creating YouTube content with Sandiaga Uno in the Ruang Sandi Podcast on YouTube.

This research examines the translation of instructions for using skin care products from English into Indonesian, focusing on translation shifts as defined by Catford (1965). These shifts include level shifts and category shifts (structure, class, unit and intra-system shifts). This research analyzes how these shifts occur and adapt to the Indonesian linguistic and cultural context. Data from brands including Wardah, Avoskin, and Garnier were collected and analyzed using a qualitative descriptive method. The findings highlight common shifts, like structural changes due to syntactic differences and word class shifts to maintain meaning. Understanding these shifts can improve translation strategies, ensuring that bilingual packaging is clear, accurate, and culturally appropriate, thus increasing consumer understanding and satisfaction.
