Natalie Ingrid Christanti Lumbantoruan, 2024. Translating Idioms in Jane Austen’s Pride and Prejudice from English into Indonesian. English Diploma Program, Vocational School, Universitas Sebelas Maret.   This report describes my internship activities at PT Anak Hebat Indonesia (AHI) from January 29th until March 23rd, 2024. The purposes of conducting the internship are 1) applying translation skills through translating and editing books, mainly translating a novel, 2) implementing and enhancing translation competencies, and 3) comprehending the stages involved in the publishing industry's process of translating and editing novels. The report focuses on the main activity of the internship, which is translating Jane Austen's Pride and Prejudice, from English into Indonesian. This novel is written by Jane Austen. It was published in 1813 and is one of English literature's most famous and appreciated works. It chronicles the lives of Elizabeth Bennet, one of the five Bennet daughters, and a nobleman named Mr Fitzwilliam Darcy. I emphasised conveying the appropriate meaning from the source language to the target language as naturally as possible by implementing Nida and Taber’s translation process. In Theory and Practice of Translation, Nida and Taber (1982) explain that the translation process consists of three main stages. The most challenging part of translating the book was translating the idioms. To solve the issues, I looked up the meaning of the idioms in dictionaries, namely the Cambridge Dictionary, Oxford Learner's Dictionary, Collins Dictionary, and Merriam-Webster Dictionary. I also looked up on Google for more references related to the idioms. I also give some recommendations for the English Diploma students who have certainly been equipped with knowledge of translation on campus with the lecturers and mentoring sessions with the professionals in the translation agencies, for the English Diploma Program who has educated its students and provided a broad knowledge of translation through theoretical classes on campus and provided us with two semesters of internship experience in the industry, and for PT Anak Hebat Indonesia (AHI) who has given me a lot of experience.
