“…A virtual laboratory is one solution when practicum lectures are conducted online (Sari et al, 2022). Previously, Biochemistry practicum lectures had been designed on a project-based basis using local materials (PjBLLM) (Sari et al, 2018). Preliminary studies on Biochemistry practicum on the topic of quantitative analysis of PjBLLM proteins can improve creative thinking skills (Sari et al, 2017).…”
This study aims to determine student perceptions of hybrid learning practicum on the topic of qualitative analysis protein-based constructivism Needham's 5-phase. This study uses a quantitative descriptive method. Perception assessment is carried out by referring to 3 dimensions of perception consisting of 4 perception indicators, namely Perception of lecturers, perception of the teaching and learning process, perception of the social environment, and perception of assessment. Data was collected using online questionnaires via google form to students taking biochemistry practicum courses using purposive sampling technique. The results showed that the perception of lecturers obtained a perception level of 74%, the perception of the teaching and learning process was 79%, the perception of the social environment was 81%, and the perception of the assessment was 78%. The percentage of the average perception level was 78%, indicating the feasibility or success of the hybrid learning practicum of qualitative analysis protein based on Needham's five-phase constructivism. Overall, it can be concluded that students' perceptions of the hybrid learning practicum on the topic of qualitative analysis protein based on constructivism Needham's five-phase got the level of perception in the good category

“…Carbohydrate qualitative analysis was designed on project-based, which utilizes local material (PjBLLM) [11]. Several previous research projects have stated that projectbased learning supports creative thinking skills [12].…”
<p>Laboratory activities can improve creative thinking skills. This study aims to develop an authentic assessment based on creative thinking skills. This research is development research with the Rowntree development model. The research stages consist of the planning stage, the development stage and the evaluation stage. Data were analyzed using CVR and test description. This study was conducted with 33 participants. This research has produced an authentic assessment instrument consisting of learning indicators, written tests, test rubrics, product rubrics and psychomotor assessment rubrics. An authentic assessment developed in the qualitative analysis of carbohydrates with a CVR value obtained is +0.70, which can be considered valid for all validated components. The authentic assessment reliability test resulted in an average score of 56.56, a standard deviation of 25.06, and test reliability of 0.82. from the analysis, it was determined that the authentic assessment based on creative thinking skills of qualitative analysis of carbohydrates with local material developed had met the valid and reliable criteria.</p><p><strong><em> </em></strong></p>
