Abstract

The creativity dimension related to cognitive, affective, psychomotor and other skills aspects. The creativity dimension is closely related to learning outcomes and students' ability to be creative in producing relevant products. One important indicator of the creativity dimension is students' imagination skills. Through good imagination skills, students will be able to predict and create patterns in the content and context of learning material. In this research, an analysis of students' imagination skills will be carried out which consists of three indicators, namely playing with possibilities, making connections, and using intuition. The research was carried out using a classroom action research approach consisting of 3 cycles, where research data was collected by giving a questionnaire consisting of 4 statements for each indicator with 5 options for each research instrument. Apart from the questionnaire method, research data was collected through random interviews and structured observation. Based on data analysis, students' imagination skills were highest in the playing with possibilities indicator at 81.05 in cycle 3. Meanwhile, students' imagination skills were lowest in the using intuitions indicator at 35.75 in cycle 1. In general, simple gamification activities were able to increase students' imagination skills between 10% - 40%.

Abstract

This community service aims to provide support and training to PKK women on Tidung Island. Service implementation is carried out using presentations, interactive discussions, and direct practice to improve the village's capacity and creativity. The objectives to be achieved by this activity are to increase knowledge about the effects of careless disposal of used cooking oil waste and to improve skills in handling used cooking oil so that it is a valuable useful treatment. Used cooking oil is waste cooking oil that has been used many times and contains carcinogenic compounds that are difficult to decompose. Both of these properties are dangerous to health and the environment if used cooking oil is consumed and discharged into the environment without change. To achieve this goal, the method that will be used in this activity is to provide health education on the effects of careless disposal of used cooking oil waste and subsequent processing practices using cooking oil into candles. The outcome of undertaking this activity is an increased understanding of the impact of used cooking oil waste on health and the environment. In addition, you can also take advantage of used cooking oil scraps to make candles.

Abstract

Abstract Technology, which is developing very rapidly in the 21st century, has an impact on various aspects of life, one of which is the world of education. Advances in computer and smartphone-based technology are a current trend. Technological developments in the world of education, for example, include the emergence of technology-based media or learning resources such as learning media with web-based Virtual Reality (VR). Web-based Virtual Reality (VR) is a new innovation in the world of education to be able to create innovations that will have an impact on increasing students' interest in learning chemistry material. Virtual Reality is a media that combines text, animation, video, images and audio in one application. The research used wes a qualitative descriptive method by providing VR research products in class and then distributing a questionnaire regarding high school students’ perceptions of VR. The results of the research show that students’ perceptions of media using virtual reality.

Abstract

Improving cognitive abilities, namely learning outcomes is one of the objectives of learning. Learning outcomes can be improved through the use of creative, innovative learning models in accordance with the current curriculum, the 2013 revised curriculum. This study aims to determine whether there is an increase in Physics Chemistry Learning Outcomes 1 through the Project-based Learning (PjBL) Learning Model using Quizizz online learning media. Based on the results of the normality and homogeneity test, the data is normally distributed with the value of the normality test result of 0.638 (sig 0.05) and homogeneous with the homogeneity test result value of 0.144 (sig 0.05). The results of statistical analysis of research data using the paired t-test hypothesis test results obtained tcount = 17,685 (sig 0.00) and ttable = 0.684 (sig 0.05), it is concluded that there is an increase in learning outcomes in Physics Chemistry 1 through the Project-based Learning (PjBL) learning model using Quizizz online learning media because tcount˃ ttable. A further test is the gain test, to determine the level of improvement in learning outcomes. The results of the analysis using the gain test, the gain value of 42.51%, with the medium category.
