<![CDATA[The STEM approach is a learning strategy to train students' creative thinking skills. This approach encourages students to conduct the engineering process by making prototypes or products to solve problems. Education for Sustainable Development (ESD) needs to be integrated into STEM learning to train students' thinking and questioning skills. This study aims to determine the improvement of ESD attitudes and creative thinking skills by using the ESD-integrated STEM approach. This study used a one-group pretest-posttest design. The research instruments used were a creative thinking skills test with creative thinking indicators and an ESD attitude questionnaire. The N-Gain test analysis obtained a result of 0.81 with a high category. The results showed that students' creative thinking skills improved significantly, and students' ESD attitudes improved very well through the STEM approach with ESD content in high school students. This research shows that the STEM approach with ESD content can be used as an alternative learning method to improve students' creative thinking skills and can contribute to the development of science by enriching the understanding of the STEM approach with ESD content, presenting a new perspective in education that focuses on sustainability and creativity.]]>

<![CDATA[A coupled spring-pendulum system in a conservative field was studied where the equation of motion of the system using Lagrangian and Hamiltonian equation were obtained. The equation of motion represented by a second-order differential equation from the three generalized coordinate were used. The potential energy equal to zero when the system is in its equilibrium position. The generalized coordinate that being used were the angle of the first pendulum θ_1, the angle of the second pendulum θ_2, and the increase in the length of the spring x. The resulting equation of motion can be used to determine the dynamics behavior of the system at any time. Students' understanding is expected to be more complete by providing a procedure to derive the Lagrangian equation of motion.]]>

<![CDATA[Paperless movement is a conservation effort. This refers to transitioning from conventional paper-based processes to replacing them with digital alternatives. The paperless movement has been globally implemented in various sectors, ranging from the corporate world to the educational sector. This movement is still little applied as a student's monumental work. This research aims to develop a book template using LaTeX for submitting assignments in the Computational Physics course. This template is designed to support the paperless movement as a conservation effort. We designed and developed a platform based on available LaTeX templates and then adapted it to the needs of computational physics courses. Instructions for using this template were also created and disseminated in learning classes. Next, we apply this template as a medium for collecting assignments and don't forget to ask students for responses regarding the use of this template. The outcome of the research is a book template that has already been used in the class. The students were very enthusiastic about learning the LaTeX program and they have been using it for document writing, especially related to mathematical equations. We hope that the development of this book template that we have carried out can become one of the conservation efforts in learning classes.]]>
