Abstract

The material of composing an equivalent force became the focus of this study. Researcher want to see deeper and broader understanding of students related to this material. One teacher's information that most students make mistakes in solving the problem in the form of a description on the subject of engineering mechanics. The purpose of this study is to describe the mistakes made by students in completing the description of the material in composing an equivalent force in the thenth grade of Construction and Property SMK Negeri 1 Palangka Raya. This research uses descriptive method with qualitative approach. Population in this research is thenth grade of Business of Construction and Property of SMK Negeri 1 Palangka Raya is 23 people. Sampling by purposive sampling so chosen 4 subject of students with criterion of student can represent every aspect in making mistake that is mistake in comprehension problem, make mathematical model, calculation and draw conclusion, and able to communicate well.
