Jogging has benefits for burning calories as well as for losing the weight of the body. However, the reality that often happens is that sportsmen overwork their body in exercising so that it has passed its normal threshold. This causes over or lower calorie burning in these athletes. To overcome these problems, we need a device that can later monitor calorie burning. This device is created on an Android-based platform using an accelerometer sensor. Using this sensor, the system can count the number of a person’s steps previously obtained through the threshold value as the threshold value to determine the steps. Calculation of calorie burning uses a formula that involves the number of footsteps, time, and weight of the user. This application testing involved 15 participants by comparing the calorie burning results through the application and manual calculation, so that the overall error percentage of 0.60% was obtained, so it can be concluded that 99.40% of the calorie burning calculation system in jogging using a thresholding-based accelerometer sensor is appropriate for athletes to provide information of their calories burning in jogging.

This research aims to develop sensor and transducer e-modules based on 4Cs skills using the Kvisoft Flipbook application to improve the quality of learning in automotive engineering. The main focus of the research is to assess the validity, practicality, and student response to the e-module design developed. The research method used is Research and Development (R&D) with the ADDIE model. Data collection techniques included validation questionnaires, user practicality questionnaires, and student response questionnaires to the e-modules. The e-module was rated highly valid by 89% of e-module experts and 88% of material experts and highly practical according to the assessment of lecturers (89.09%) and students (81.81%). The evaluation showed that students who used the e-module achieved a higher average score than the control group, signalling the effectiveness of the e-module in improving critical thinking skills, communication, collaboration, creativity (4Cs), and material understanding. These findings emphasize the importance of technology integration in vocational education to prepare students for the challenges of the Industrial Revolution 4.0 and encourage innovation in teaching methodologies.

This study aims to analyze the influence of da'wah content on TikTok on the strengthening of adolescent moral values. Using a quantitative approach, this study involved 31 adolescents in Kubang Agung Village as the sample. Data were collected through a questionnaire and analyzed using a simple regression test. The results show that da'wah content on TikTok has a significant influence on the strengthening of adolescent moral values, with a significance value of 0.001 (p 0.05). The coefficient of determination (R²) of 0.314 indicates that 31.4% of the variation in adolescent moral values can be explained by TikTok da'wah content, while the remaining 68.6% is influenced by other factors outside the study. Overall, this research concludes that TikTok can function as an effective da'wah medium, capable of conveying moral values creatively and in an easily accessible way for adolescents, provided it is used wisely and supported by a holistic moral education ecosystem.
