Abstract

Practical activities during the covid pandemic are difficult to do because all learning has turned to online learning. So that students are required to carry out independent practicum at home, even though laboratory equipment and materials are quite expensive and difficult to obtain. A breakthrough is needed so that the practicum can still be carried out. One of them is independent practicum using simple equipment and materials. Independent practicum is implemented in basic chemistry courses during the odd semester. However, reflection on the practicum is needed to identify motivation and an opinion from student. The research design used was descriptive qualitative research. The research was conducted on students of the Chemical Education Study Program, University of Lampung. Data was collected by using a questionnaire through a Mentimeter. The results showed that (1) students were highly motivated to participate in independent practicum because it was interesting, (2) students' perception of independent practicum is very good, this is shown by the number of students who are helped in understanding the concept of chemistry after doing independent practicum, (3) the obstacle experienced by students during independent practicum is the difficulty of signaling in some areas which causes the upload of independent practicum videos to be often late. This research is relevant and can be a practical breakthrough for both lecturers and teachers who have limited laboratory equipment and materials by loosening the collecting of practicum videos.

Abstract

Chemistry practicum is still only concept verification or is a cookbook.This study aims to develop student worksheets on producing jelly as a colloid product by using perdu cincau leaves (Premna Oblongifolia). The method used in this study is development research with ADDIE models (Analysis, Design, Development, Implementation, Evaluation), which only done until development step. Analysis curricula of colloid topic and study of literature on project-based practicum and perdu cincau leaves have been carried out at analysis step. At this step also interviewed high school teachers and found that there is no student worksheets for supporting KD 4.15. At design step, the experiment of jelly producing using perdu cincau leaves was optimized and the best laboratory work design was obtained, such as materials, tools and procedures. Then, a project-based laboratory worksheet draft was created and validated by experts. Based on the suggestions given by the validator, content number 11 was omitted because it contained irrelevant instructions. Content number 2 added instructions. Content number 15 and 16 an explanation is added. Content number 3, 4 and 12, it is necessary to edit sentences. After revising, student worksheets is ready to be implemented in learning activities.
