Abstract

During the pandemic, healthy life behavior is needed in an attempt to reduce the transmission risk.  One of them could be done by washing hands. Various human activities may not allow them to wash their hands frequently, for example, using hand sanitizer to wash hands. Hand sanitizer or Isopropyl based alcohol are recommended materials by WHO to clean bacteria on hands. Storing hand sanitizer for a longer time leads to inaccurate quality of the hand sanitizer to the written quality on the package. A simple alcohol meter is designed to test the liquid percentage of hand sanitizer or Isopropyl Alcohol (IPA) based alcohol. The required materials are easy to get from the surrounding environment. Thus, this device could be established at home without ignoring the health protocol. Although it has strength IPA-based alcohol or hand sanitizer is also risky if it is incorrectly used

Abstract

Abstract. Science learning is inseparable from practice activities or experiments. A laboratory is a facility to promote these activities. During distance learning, laboratory activities could be promoted at home. This research aims to portray the students' activities during the laboratory practice and to find out the students’ perceptions about the laboratory practice and take-home laboratory practice. The applied method was a survey followed by 80 physics education students of Universitas Pattimura. This research also interviewed three lecturers of the program. Before distributing the questionnaire, the question items were validated in terms of the content. Then, the researchers also examined the reliability of the questionnaire. The findings showed that students did the laboratory practice as they frequently did. They started by having a pretest and ended with a posttest. They also created temporal reports and practical reports for the following meetings. The students were interested in the practice activities because they believed these activities could make them having various skills. Some students recognized the term, take-home practice, by using any surrounding tools and materials. However, most students still considered that laboratory activities should have been done in the laboratory.
