Abstract

Evaluating the quality of test instruments is an important step in ensuring the acceptability and accuracy of measuring student learning outcomes. This study aims to analyze the quality of 50 multiple-choice questions in the Introduction to the Oil and Gas Industry course in terms of validity, reliability, difficulty level, and discriminatory power. The method used is quantitative item analysis with a descriptive and inferential statistical approach based on the results of validity tests, reliability using Cronbach's Alpha, difficulty level, and discriminatory power. The analysis results show that most of the items are valid. The reliability test obtained a Cronbach's Alpha value of 0.88 which is included in the high category, indicating good internal consistency of the instrument. The level of difficulty of the questions is predominantly in the medium category, while the discriminatory power is mostly in the good category. However, several items were still found to be invalid and have low discriminatory power so that they need to be revised or removed. Overall, the test instrument in the Introduction to the Oil and Gas Industry course can be categorized as good quality and suitable for use with improvements to certain items.

Abstract

The absence of a standardized essay item bank for the Petrochemistry course in the Oil and Gas Processing Engineering Diploma (D3) Program at Sekolah Tinggi Teknologi Migas has led to an ad hoc test-construction practice with no guaranteed representation across cognitive levels. This study aims to develop an essay item bank for the third-semester Petrochemistry course referring to the Revised Bloom's Taxonomy (C1–C6), while analyzing the clarity of instructional construction and the linguistic correctness of each item with the assistance of Artificial Intelligence (AI). This Research and Development study adapted curriculum-need analysis, blueprint construction, item writing, and AI-assisted quality analysis stages, with 50 essay items distributed across nine Petrochemistry topics as the research object. Data were analyzed descriptively-quantitatively for item distribution and descriptively-qualitatively for construction and language analysis results. The findings show that the 50 essay items were evenly distributed across the six Revised Bloom's Taxonomy levels (C1 8 items, C2 8 items, C3 8 items, C4 9 items, C5 8 items, and C6 9 items) and across nine Petrochemistry topics, ranging from Introduction to the Petrochemical Industry to Petrochemical Industry Equipment. The AI-based analysis indicated that all items used clear operational verbs appropriate to the targeted cognitive level and complied with standard Indonesian language rules and sentence effectiveness, confirming the item bank's feasibility as an evaluation instrument. This essay item bank represents the first standardized evaluation instrument for the Petrochemistry course at Sekolah Tinggi Teknologi Migas and is recommended for replication in other courses within oil-and-gas vocational education.
