This study aimed to describe and explain the types of onomatopoeia found in Raditya Dika’s novel Manusia Setengah Salmon. Onomatopoeia refers to a word whose phonetic structure mimics a natural sound to represent the sound or action of the object that produces it. Onomatopoeia behaves differently in comparison to other processes of word formation. Its meaning lies outside the language itself due to its nature which is adopted from the natural sound. The data analysis technique was used in this research with descriptive qualitative analysis. The descriptive research attempted to describe and explain the data according to the theory proposed by Thomas (2004) who divides onomatopoeia into four groups based on the source of the sound: calls of animals, sounds of nature, sounds made by human, and sounds of other objects. Based on the result, the four types of onomatopoeia were found in the novel under research: human onomatopoeia, animal onomatopoeia, object onomatopoeia, and daily life onomatopoeia. From the word class, onomatopoeic words used in the novel consists of adverb, adjective, noun, and verb.
