Abstract

Students consider fractions to be complex material. The results of the dialogue on preliminary observations with a mathematics subject teacher at a junior high school in Malang showed that many students could not model problems in the form of mathematics. According to the Newman stage, this study aims to analyze students' mistakes in working on story questions about fractions. This type of research is descriptive qualitative research. A total of 23 students were given instruments in the form of 2 fraction test questions. Based on the test scores obtained, the students were categorized (high, medium, and low), and two subjects were selected for each category for the interview. They were checking the validity of the findings using the triangulation technique, namely, by comparing the results of direct observation, student test results, and interview data. Based on the research results, there were three biggest mistakes of the students: transformation errors, reading errors, and misunderstanding of the questions. Further research is recommended that students be given more story questions about solving fraction problems so that similar errors do not happen again

Abstract

Network analysis is part of a project that requires time for each network activity. To produce a particular project there is more than one job/event that must be done. Each job/event is interconnected and placed in order according to the management of its implementation. In network projects, it is necessary to plan and supervise systematically, in order to obtain work efficiency. The network is represented in symbols and arrows. In this study, the problem-solving network analysis was solved using the CPM (Critical Path Method) method and with a linear programming model using the help of excel-solver and Lingo. This study aims to compare the two methods in solving network analysis problems. Based on the analysis, it is found that by using the CPM method, more critical paths are obtained than the linear programming method. With the increasing number of critical paths obtained, it is hoped that the management can determine project priorities to maintain the project schedule to be completed on time.
