Practical lectures should be held face-to-face. The COVID-19 outbreak that hit Indonesia and the world in general made practicum lectures unable to run as they should. This study aims to develop a Virtual Laboratory in the Practicum course. The purpose of this research is to develop a Virtual Laboratory in Biochemistry Practicum. This research is development research with the ADDIE development model from Dick and Carry, namely a development model consisting of five stages which include analysis, design, development, implementation, and evaluation. The results of laboratory development validation show the Aiken coefficient of 0.87 for material experts and 0.92 for media experts. The results of the implementation show practicality of 94.45%. It can be concluded that the virtual laboratory developed in the Biochemistry practicum is valid and practical

The purpose of this study was to analyze creative thinking skills in the use of local materials as reagents in qualitative biochemical practices. The use of local material reagents can improve students’ creative thinking skills. This research method is quasi-experimental design with pre-test post-test group design. The research instrument consisted of pre-test and post-test questions using tests of creative thinking skills in the form of descriptions and student questionnaires. Data analysis was performed using the SPSS 22.0 program and the percentage of student responses to the practicum was carried out. The results showed that the average claim score of the experimental group was 59.95 and the post-test score was 80.00 with N_Gain 0.50 in the moderate category. In the control group the average pretest score was 38.70 and the posttest score was 44.80 with the lowest category N_Gain 0.09. Further analysis was carried out on each indicator of creative thinking skills which reached 23.16% fluency, 40.28% flexibility, 17.50% originality and 19.06% elaboration. It can be concluded that the use of local materials as reagents in the project-based qualitative biochemical analysis laboratory can improve students’ creative thinking skills, especially in terms of originality and elaboration.

<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>
