Profile of Students’ Science Process Skills in Acid Base Titration Practicum at Class XI MIPA 3 SMA Negeri 1 Singaraja Bali

Abstract

The research was aimed to describe the profile of students’ science process skills and the factors that influence science process skills of class XI MIPA 3 SMA Negeri 1 Singaraja in the implementation of acid base titration practicum. This research conducted by using a phenomenological qualitative approach. The methods that used to collect data were observation, interviews, and documentation. Data were analyzed by qualitative descriptive techniques. The result that obtained is profile of students’ science process skills at class XI MIPA 3 SMA N 1 Singaraja which is limited to mastery of science process skills. Science process skills that have been mastered by students consist of 7 aspects of skills, namely skill to measure the volume of the solution with volumetric pipette and burette included in the good category with the number of students 100%; the skill to use universal indicator, communication skills, and applying concepts included in the excellent category with the number of students 100%; observing skill, titration skill, and interpreting skill included in the excellent category with the number of students 60%; and predicting skill included in the excellent category with the number of students 80%. Skill that is less mastered by students was concluding skills based on the results that 60% students included in the poor category. Science process skills that are not trained for students consist of 4 skills, namely the skills of formulating hypotheses, controlling variables, designing investigations, and classifying. The factors that influence students’ science process skills in the implementation of acid base titration practicum are classified into four factors, namely tools, materials, humans, and methods/technical.
