Abstract

This study aims to determine the profile of misconceptions among public high school students in Surakarta regarding static fluid material. The method used in this study is quantitative with a descriptive-exploratory type. The population of this study consists of all public high school students in Surakarta. The sampling technique used in this study is cluster random sampling, resulting in a sample of 150 eleventh-grade students from Public High Schools 1, 3, and 5 in Surakarta. The researcher used a Four-Tier Automatic Diagnostic Test, developed on Jotform, to identify misconceptions. This instrument is an adaptation of a previous three-tier test. The instrument validation techniques used were validity and reliability tests. The validity test of the instrument consisted of internal validity (validation of the questions and media) and external validity (difficulty level, discriminative power, and the effectiveness of distractors). The data analysis technique employed was descriptive analysis, based on the results of the Four-Tier Automatic Diagnostic Test instrument. The analysis results showed that the percentage of misconceptions among high school students in Surakarta on static fluid material was 12%. The largest misconception among students was related to Pascal^s Law, affecting 24%, while the smallest misconception was related to hydrostatic pressure, at 6%. Some of the profile misconceptions found were that hydrostatic pressure depends on the shape and size of the container, a hole positioned on the side will emit water most forcefully, and the magnitude of Archimedes^ force is influenced by the volume of fluid in the container.
