Analysis of Indonesian Writing Errors in Chemistry Laboratory Reports at Medan State University

Abstract

This study aims to analyze Indonesian language writing errors in chemistry practicum reports of PSKM 24 A students at Universitas Negeri Medan. This research employed a descriptive qualitative method with documentation as the data collection technique. The data sources were obtained from students’ practicum reports which were analyzed based on the guidelines of Pedoman Umum Ejaan Bahasa Indonesia (PUEBI). The results showed that there were still various Indonesian language writing errors in students’ practicum reports, including errors in the use of capital letters, punctuation marks, standard words, prepositions, scientific terms, citations, and effective sentences. The most dominant errors found were punctuation and ineffective sentence usage. These errors were caused by students’ lack of understanding of Indonesian language rules and scientific writing, as well as lack of accuracy in preparing practicum reports. This study is expected to serve as an evaluation material for students in improving scientific writing skills and as a reference in teaching scientific writing at universities.
