Abstract

One of the 21st-century skills that needs to be developed is problem-solving. Problem-solving ability is understanding problems, planning solutions, applying solutions, evaluating, and finding solutions to problems. In fact, problem-solving ability in chemistry learning is still low, so a strategy is needed to overcome this problem, one of which is the application of project-based learning. Project-based learning is a learning model that involves students directly in the learning process through research activities. This study aims to evaluate the effect of implementing the Project-Based Learning (PjBL) model on students' problem-solving skills in learning chemistry. The method used is a Systematic Literature Review (SLR). Articles were obtained from Google Scholar, Scopus, and DOAJ, and 9 articles met the inclusion criteria set and were analyzed further. The results of the analysis show that the PjBL model has a positive influence on students' problem-solving skills. Project-based learning allows learners to be creative, work together, and develop solutions within a particular time, improving their collaboration, communication, and critical thinking skills. Implementing PjBL also provides a more interesting and realistic learning experience, helping learners understand the learning material and practice practical skills. Overall, implementing PjBL shows positive results in achieving chemistry learning objectives in cognitive, affective, and psychomotor domains.      Keywords: chemistry learning, problem-solving, project-based learning.

Abstract

In 2020 cases of Covid-19 were found in various parts of the world, one of which was in Indonesia. Since it was first discovered, this case has continued to increase, with DKI Jakarta Province being the highest contributor to daily positive cases of Covid-19 in Indonesia. The Indonesian government continues to make efforts and cooperation between institutions. One of the institutions it has is the Health Agency. However, the arrangements and working conditions that have changed following the development of the Covid-19 case can cause fatigue for employees of the DKI Jakarta Health Agency.. This study aims to analyze the relationship between work-related risk factors (working hours, effort, work rewards, overcommitment, social support, and job satisfaction) and non-work-related (sleep quantity, sleep quality, health status, educational status, stress, and age) on employees of Jakarta Health Agency against fatigue. This study used a cross-sectional research design with primary data collection using a questionnaire. The results of research based on MFI found that 64 employees (45.7%) experienced general fatigue, 67 employees (47.9%) experienced physical fatigue, 67 employees (47.9%) experienced mental fatigue, 47 employees (33.6%) experienced reduced activity, and as many as 65 employees (46.4%) experienced reduced motivation with variables having a p-value
