Abstract

Life skills are needed in this era of globalization to be successful in the school environment or outside of school. According to the 2019 World Economic Forum, the world's demand for STEM qualifications and skills is very high now and is likely to continue to increase in the future. Today, 75% of the fastest-growing industrial-scale jobs require skilled STEM workers. Faced with this, to be able to compete, the world of work requires people who can adapt to their new work environment. STEM can empower individuals with the skills to succeed and adapt to new work environments. To get individuals who have STEM skills, individuals who have 21st-century skills are needed. This is because in 21st-century skills 3 skills must be met, namely learning skills, reading and writing skills, and life skills. The purpose of this study was to determine the feasibility of the PBL-STEM module developed for prospective Biology teacher students as an effort to improve 21st-century skills. The method used was the Rosset-based RnD ADDIE model. The ADDIE Teaching Model includes 5 stages, namely analysis, design, development, implementation, and evaluation. The results of the material expert validation show that the average score of the material expert validation results shows a fairly good category with an average of 2.94. The results of practitioner validation show that the average score of practitioner validation results shows a good category with an average of 3.56. The results of the small group readability test showed that the average score on the small group readability test was in the good category with an average score of 3.39.

Abstract

One of the Basic Competencies (KD) in Biology for Indonesian Senior High School is KD 4.12 which reads "Presents observations of the process of mitosis in the onion root and determines the phases it finds". Based on the basic competency test, students are required to have skills in making and observing mitotic preparations of plant tissue with at least using onion. Observation of mitotic division in plant tissues requires skill in making preparations. Making preparations in observing cells and tissues of plants or animals needs staining. Dyes often used in lab work are synthetic dyes. One of the synthetic dyes commonly used is safranin. However, safranin is quite expensive. This limitation requires teachers to look for alternatives to synthetic dyes that are easily found at a more affordable price, namely with natural dyes. One of the plants that has the potential to overcome this issue is beetroot (Beta vulgaris). The purpose of this study was to determine the quality of plant tissue preparations (Allium cepa) stained with beetroot skin (Beta vulgaris) as a natural coloring agent. The research method used was an experimental method with a Completely Randomized Design consisting of two factors, namely the staining time (1 hour, 2 hours, and 3 hours) and the type of solvent (aquades and citric acid 10%). The results of the study were analyzed with qualitative descriptive methods which included contrast and clarity of the preparations. Based on the results of the study, the quality of Allium cepa root preparations using beetroot (Beta vulgaris) skin extract with variations in the type of solvent and duration of staining showed good results on the staining time of 1 hour and 2 hours. The staining time of the preparations can affect the contrast and clarity of the preparations.
