This research was motivated by the lack of teaching materials that align with the characteristics and needs of students. One of the main issues identified is the use of learning modules that are not yet adapted to local culture and fail to provide meaningful learning experiences. To address this problem, the researcher developed a culturally based module inspired by Minangkabau songket. This study employed a Research and Development (R&D) design following the development stages proposed by Sugiyono. The results show that the developed module achieved a validity level of 82.58% (categorized as very valid), a practicality level of 87.6% (very practical), and an effectiveness level of 83.3% (very effective). Based on these findings, it can be concluded that the ethnomathematics-based module on Minangkabau songket for Phase F of the Health Department at SMAN 1 Lareh Sago Halaban in the 2023/2024 academic year meets the criteria of being valid, practical, and effective. Therefore, it is considered suitable for use as a culturally contextual teaching material that integrates local values into the learning process.

Renewable energy is non-fossil energy that can be renewed and managed sustainably, such as solar, wind, water, and biomass. To overcome dependence on weather conditions, this energy can be combined with alternative energy sources such as piezoelectric sensors, which can convert pressure into electrical energy. This study aims to design a prototype monitoring system for hybrid electric energy using solar panels, wind turbines, and piezoelectric elements as alternative energy sources on board ships. The use of Internet of Things (IoT) technology is key to monitoring and managing these energy sources in real-time and automatically through integrated sensors and software. This research uses the Research and Development (R&D) method by creating a prototype that combines solar panels, wind turbines, and piezoelectric components as energy sources and designing a monitoring system based on the Internet of Things (IoT) using the Kodular application. Several system components were tested through two types of testing: static and dynamic testing. The test results showed that the solar panel had the most stable performance with a voltage of approximately 16.50V and a current of 2.41A occurring between 13:00 and 16:00 WIB. The wind turbine was able to operate at low wind speeds and reached its highest voltage of 3.63V and current of 1.14A on the fifth day at 20:00 WIB with a wind speed of 1.1 knots. The piezoelectric system generated power according to the pressure and frequency of footstep impacts. The highest voltage recorded for a 70kg subject was 4.11V with a current of 0.19A. This hybrid system has the potential to be an environmentally friendly energy support solution on board ships.

This research is motivated because the teaching materials used are still conventional and students' understanding of problem solving is still in the low category. Therefore, this study aims to develop research and improve the validity, practicality and effectiveness of the Science learning module for Class V MI Muhajirin, Jambi City. Reach and Development (R&D) consists of four stages, namely, define, design, develop and disseminate. This type of research is Research and Development (R&D). This research was conducted at Madrasah Ibtidaiyah Al-Muhajirin, Jambi City. The instruments used were assessment questionnaires, teacher and student interview sheets along with test questions. The subjects in this study were grade V students consisting of 20 students. The results of this study indicate that the level of validity of the application of the learning module shows a percentage of 80% included in the very effective category, the level of practicality shows 92.8% with a very practical category and the level of effectiveness shows a percentage of 64.2% with a very valid category.

To improve the quality of education and learning in learning speaking in the English Education Department. Consideration of the lack of confidence in students caused by not knowing how to perform appropriately and well to appear confident to improve their speaking skill is also supported by the existence of appropriate learning media and can facilitate both students and teachers in learning to speak.  Therefore, researchers conducted research and development of Speech Practice book learning media namely “A Guide Speech Practice Book to Elevate Your Performance” The research aims to describe the design development and feasibility of the product. This type of research is Research and Development (R&D) which follows the procedure of Borg and Gall. Which includes ten stages and then simplified into five stages which include: need analysis, product development, expert validation, product try-out, and final product. After going through several stages, the product feasibility assessment was started based on the results of experts which included content experts and design expert. Based on validation from the content expert with an average value of 4.6 with a percentage of 92% with a very feasible category. The results of validation from design expert get an average value of 4.5 with a percentage of 90% with a very feasible category. Then the product validation results of student responses get a total score of 3064 with a percentage of 94.2% with a category very feasible. based on the results of research and field tests that have been described, it can be concluded that the speech practice book for students speaking skill at the English Education Department is very feasible to use for speaking learning.

This research is based on the problems found based on the results of interviews with mathematics teachers and students at SMPN 1 Lareh Sago Halaban that the media used in the learning process only uses the blackboard with lecture and discussion methods, there is no technology-based learning media, especially educational games that are used by teachers to students related to mathematics lessons caused a lack of interest and activeness of students in mathematics subjects. Based on this, the solution given is to design a learning media. The purpose of this research is to produce learning media products in the form of educational games with the help of software Building 2 mathematics subjects at SMPN 1 Lareh Sago Halaban. The design of mathematics education games uses the construct 2 design application at SMPN 1 Lareh Sago Halaban with the Research and Development (R&D) research method using the MDLC (Multimedia Development Life Cycle) development model from Luther Sutopo the development model is explained in 6 stages, namely Concept, Design, Materials Collection, Assembly, Testing and Distribution. The product test used in the research is the validity test, practicality test, and effectiveness test. The product test results show that the educational games designed are valid, practical and effective. For the results of the validity test of three validators, the score was 0.88, the practical test by 3 practi- tators was 0.97, and the effectiveness test of twenty people was 0.92.
