Abstract

Big changes have occurred in the 21st century due to technological advances and rapid developments in various fields. The key to success in facing the challenges of the 21st century is scientific literacy, namely the ability to understand, communicate and apply scientific concepts in real life. However, in reality, practicing 21st-century skills is still rarely done because learning is teacher-centered. This research aims to improve students' scientific literacy skills through a problem-based learning model. The research was conducted in class X MS 4 with 28 students. The research was carried out in two cycles, each consisting of 4 stages: planning, implementation, observation for evaluation, and reflection. From the comparative analysis of scientific literacy abilities in cycles 1 and cycle 2, it was found that scientific literacy abilities in cycle 1 with an average score of 67 in the middle category experienced an increase in cycle 2 with an average score of 77 in the high categories. Based on the research results, it can be concluded that applying the problem-based learning model can improve students' scientific literacy abilities in physics materials.

Abstract

Local wisdom-based learning is one of the innovative approaches in science education that enhances the relevance of scientific knowledge to everyday life. One form of local wisdom that can be studied from an ethnoscientific perspective is the production of durian tempoyak in Indragiri Hilir, Riau. The fermentation process of durian tempoyak involves scientific concepts in biology and chemistry, such as microorganism activity, fermentation reactions, and changes in food's physical and chemical properties. However, research on integrating local wisdom into science education remains very limited. This study aims to analyze local wisdom in the production of durian tempoyak from a scientific perspective. Data were collected through interviews with informants selected using the snowball sampling method. Data analysis was conducted using the Miles and Huberman qualitative approach. The research findings indicate that the Malay community continues to preserve the tradition of making durian tempoyak. The production process includes preparing materials and tools, fermentation stages, and its benefits in science learning. In conclusion, exploring ethnoscience in durian tempoyak production provides an opportunity to link science with local culture, particularly in biotechnology. Integrating local wisdom into science education will enhance students’ appreciation of culture and develop 21st-century skills.

Abstract

This study aims to describe the development process and feasibility of Project Based Learning (PJBL) based interactive multimedia developed using Lumi on the topic of cells. The research employed a research and development (R&D) approach, adopting the ADDIE instructional design model, which consists of five stages: analysis, design, development, implementation, and evaluation. The feasibility of the developed multimedia was evaluated by experts in terms of validity and practicality. The results indicated that the PJBL based interactive multimedia developed using Lumi was deemed highly feasible, with an average Aiken’s validity index of 0.85 (very high). The practicality assessment also demonstrated very positive results, with average scores of 93.93 (very practical) from teachers and 91.10 (very practical) from students. The validity evaluation covered four aspects—design, pedagogy, content, and technique—yielding average scores of 0.87, 0.80, 0.85, and 0.86, respectively. These findings suggest that the PJBL based interactive multimedia developed using Lumi is both valid and practical, making it suitable for enhancing the science learning process in junior high schools, particularly in teaching cell conceptsKeywords: cell, development, interactive multimedia, lumi, PJBL

Abstract

This research aims to determine the increase in creative thinking skills of secondary school students through the application of the PjBL model with a STEAM approach to energy materials in living systems. This research uses a true experimental method with a pretest-posttest control group design. The population of this study was all class VII students. The sample selection used a simple random sampling technique so that one experimental class was selected which applied the PjBL model with the STEAM approach and one control class which applied the conventional learning model. Data collection was carried out through creative thinking skills test questions and observation sheets. Posttest data on students' creative thinking skills were analyzed using the Mann-Whitney test, and observation sheets were analyzed using descriptive analysis. The results of the analysis using the N-gain test in the control class obtained a value of 47,4 in the medium category and the experimental class with an N-gain of 71 in the high category. It can be concluded that there is a significant increase in students' creative thinking skilss after learning using the PjBL model with the STEAM approach in learning Energy in Living Systems.Keywords: project based learning, steam, creative thinking skills, energy in living systems

Abstract

The purpose of this study is to test and analyze the effect of work motivation and leadership style on employee productivity at PT. Andalan Mandiri Busana Boyolali. The focus of the study is directed at the sewing division which has a crucial role in the production process. The method approach in this study is quantitative explanatory. This study involved 100 respondents from employees of PT. Andalan Mandiri Busana Boyolali who were selected using purposive sampling techniques based on certain criteria. Data collection was carried out through a Likert-based questionnaire, then the data was analyzed through multiple linear regression tests with SPSS 25 software. The results of the analysis showed that work motivation had a positive and significant effect on employee productivity. Likewise, leadership style contributed significantly to improving workforce performance. Together, all independent variables have a major effect on increasing the productivity of the company's workforce. The results of the statistical test showed that the coefficient of determination (R²) had a fairly high value, indicating that the variables of work motivation and leadership style were able to explain most of the variability in employee productivity. Furthermore, recommendations for management are to develop strategies to increase motivation and implement an adaptive and participatory leadership style to increase work efficiency and effectiveness in the company environment.
