Currently, an influential factor contributing to thermal comfort home design is the incorporation of energy-efficient passive design principles. It is exemplified by strategic window placement, the utilization of thermally efficient materials, and effective insulation. It exerts a substantial influence on thermal comfort and electrical consumption. This paper examines the effect of building shape and window-to-wall ratio (WWR) on thermal comfort and lighting energy consumption in residential houses in tropical climates. The lighting electricity and the adaptive thermal discomfort hours of 30 different models of houses were obtained using OpenStudio and EnergyPlus simulation software. The models were developed for three building shapes (square, rectangle, and L-shaped), and each model was varied in five models of window-to-wall ratios. Results indicate that the square-shaped model with a WWR of 10% will provide the lowest energy consumption in thermal comfort had 420.45 kWh/m2. On the other side, the lowest energy consumption in lighting is the square-shaped model with a WWR of 50% had 507.95 kWh/m2. Thus, the recommendation is to use the square-shaped house that represents the most efficient air conditioning system while the other WWR set also produce the most natural luminaire. It is because the percentage of WWR increased will result in more energy consumption in air cooling but slightly lower energy consumption in lighting. However, when considering aesthetics and freshness, the WWR of the 50% model will offer a better deal.

Banyak alumni sekolah menengah Kejuruan (SMK) dan perguruan tinggi masih belum memahami cara menggunakan software CAM. Ini karena banyak guru teknik pemesinan, terutama di Sumatera Barat, belum terbiasa menggunakan software CAM. Software ini baru hadir di Indonesia beberapa tahun di awal tahun 2000. Akibatnya, guru tidak dapat memberikan pembelajaran yang optimal tentang pengopersian software ini kepada siswa mereka. Namun, ada banyak guru yang ingin belajar dan meningkatkan penggunaan software ini, tetapi belum ada alat yang membantu mereka melakukannya. Dengan demikian, guru teknik pemesinan khusus bidang CNC & CAM tidak memiliki kompetensi yang sama di berbagai wilayah Sumatera Barat. Oleh karena itu, diperlukan upskilling dan reskilling ilmu CNC & CAM untuk memastikan bahwa kompetensi guru keahlian teknik pemesinan SMK di Sumatera Barat meningkat dan mampu menghasilkan lulusan yang unggul dan siap kerja. Pelatihan ini bertujuan untuk meningkatkan wawasan dan pemahaman guru tentang penggunaan perangkat software CAM pada mata pelajaran Pemrograman Mesin NC/CNC dan CAM. Kegiatan ini diberikan dalam rangka peningkatan kompetensi (upskilling and reskilling) dan guru adalah pelatihan dan pendidikan penggunaan software CAM. Metode yang digunakan termasuk identifikasi masalah, penugasan, diskusi, kerj Dengan kerja sama yang baik antara dinas pendidikan dan MGMP (Musyawarah Guru Mata Pelajaran) bidang keahlian teknik pemesinan, diharapkan pelatihan ini akan berlangsung sesuai rencana. Sekitar dua puluh guru akan dilatih. Kegiatan ini akan diadakan di SMKN 2 Payakumbuh pada bulan September 2023.

The use of solar energy is very important to increase today because solar energy is renewable energy and also does not cause pollution, but solar collector equipment is still needed to convert solar energy into heat energy. This study aims to analyze the heat transfer in the flat plate solar collector which is used as a source of thermal energy in the water heating process for bathing. A solar collector is used to absorb solar thermal energy and then transfer it to a water pipe. The pipe material uses copper which has a very high conductivity value with an outer diameter of 5/8 '' (15.7 mm). The collector plate uses aluminum plates, because aluminum plates are quite high heat conductors. The dimensions of the box / collector frame are 150 cm long, 80 cm wide and 80 cm high. The collector frame is made of steel, with an angle of 15 ˚ of the tool. The results of the study in sunny weather conditions 46.8 c, then the results in the form of sunny cloudy weather produce an outflow water temperature of 44.3 c and finally the results data collection in the form of cloudy weather the results obtained are 38.3 c. Based on the experimental process, the collector temperature was taken using a thermocouple,heat the water to the initial temperature in a bucket of 28˚c and the temperature of the water out during the study to produce 40˚c.

The aim of this study is to explore the relationship between the use of AI chatbots and learning outcomes in the field of basic mechanical engineering among students of SMK Negeri 1 Lintau Buo. Although conventional teaching methods are used, this study is considered necessary due to the insufficient learning performance of the students in meeting the minimum completion criteria. The research method used in this study is quasi-experimental, this is a form of quantitative research. The participants were 59 students of class X of the mechanical engineering program. The analysis of the data showed that both the data come from populations with normal distribution and homogeneity. This has been confirmed by Liliefors and Fisher normality tests. Due to the fact that the calculated t-value of 2.341 exceeded the decisive t-value of 2.002, the results demonstrated the rejection of the null hypothesis (H0) and the acceptance of the alternative hypothesis (H1) at a significance level of 0.05. This was evidenced by a substantial improvement in the average pupils in the experimental group's post-test results, rising from an initial average score of 66.2 to 83.58 after the implementation of the AI chatbot as an educational support platform.

The role of education is crucial in individual self-development to overcome faced challenges. The learning process is a fundamental means to enhance this educational role. However, to support an effective learning process, appropriate media is needed to ensure that information received by students is more easily understood. At SMKS Dhuafa Padang, for the lathe machining technique subject, learning media is still limited to whiteboards, textbooks, and PowerPoint presentations, which create student dependency on teachers. The lack of visualization in learning results in students having difficulty understanding the material. Therefore, E-modules become a solution to improve the quality of lathe machining technique learning. E-modules allow students to learn independently with neatly and systematically arranged material, stronger visualization, and interactivity. In conducting this research, the researcher used a Research and Development (R&D) approach and employed the Instructional Development Institute (IDI) development procedure, which has three steps: Define (needs analysis), Develop (e-module media design), and Evaluate (Validity Evaluation). The research instrument used questionnaires filled out by validators (teachers and lecturers), and the research results showed a score of 0.925 for material validity and 0.903 for media validity, indicating that this e-module media is feasible and valid for application as learning media. It is hoped that with the existence of this E-module, it can be utilized as additional learning media in the Lathe Machining Technique learning process.

Implementing Occupational Safety and Health (OSH) is a way to prevent occupational hazards. Initial observations showed that students did not follow the OHS guidelines. This problem is suspicious because SMK has not established safety measures in the workplace. Students still do not understand OHS, so it requires development so that the application of work safety can adjusted to normal demands of industry. If this is left unchecked, SMK graduates will become less capable. The Destination of occupational safety and health is to establish a prosperous, safe, and healthy work environment and society. With OHS, a workforce that is free from accidents and has good physical, mental and social health will create a safe working environment. The purpose of implementing OSH is very important to maximise the results achieved because it ensures the safety and security of workers, as well as the security of facilities and infrastructure, and prevents accidents. This study found a significant relationship between OHS knowledge and student learning outcomes, as evidenced by the test results. Twenty students from grades XI and XII in the Mechanical Engineering Department participated in this study during January - June 2023/2024. The value showed a Substansial relationship between OHS knowledge and student performance at SMK Pembangunan Bukittinggi. This was confirmed by the regression test results, with an R value > 0.657 which R table value of 0.444, thus supporting the research hypothesis.

Most of the teaching and learning of Manufacturing Engineering Drawing is still teacher-centered. Learning with the conventional model previously used made students passive and not independent in their learning. As a result, students are unable to understand the basic concepts of CAD drawings, interpret drawings, and understand the function of tools found in AutoCAD tools. This makes student learning achievements far from the minimum graduation criteria set by SMKN 5 Padang. The use of the Team Based Project learning model in this research aims to see its effect on student learning outcomes. Cluster random sampling is a sampling technique. To collect data, a pretest was carried out before the two groups were given different treatments. After the treatment, a post-test and assessment of student performance was carried out. The results of the analysis show that there are significant differences in learning outcomes. The test results showed an average in the cognitive domain of 88.7 for the experimental class and 82.58 for the control class, in the psychomotor domain 81.76 for the experimental class and 74.11 for the control class. Then the sign value from the T-test and F-test results is <0.05. Therefore, it can be concluded that the use of the Team Based Project learning model has a significant influence on student learning outcomes in Manufacturing Engineering Drawing.
