The author observes that the use of belt grinding is still rare in the writer's own environment, both in the fields of education and small industries, because there are still many people who are fixated on ordinary grinders, and think that ordinary grinders are better in all work. The development of belt grinders has changed people's perspectives through the development that the authors have done, with increasing belt grinding functions through development which will certainly make belt grinders even more useful. This belt burrs are made and developed through pre-existing belt grinding shapes. The result of this development is a belt grinder which has a function more than the belt grinder which is already before. This belt burrs has three types of work functions, namely vertical, horizontal, and cutter, and also features speed control. With the development that the author does, of course, it will change people's perspectives because belt grinding has a function that is better than before and can better help the work of a grinding process.

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.

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.

In recent years, the exploration of polyvinyl alcohol (PVA) composites has garnered significant attention due to their versatility applications in aqueous environments. However, despite their promise, neat PVA exhibit limitations such as significant mechanical degradation under repeated swelling cycles. This study investigates the durability and tribological performance of polyvinyl alcohol (PVA) composites reinforced with nickel-iron layered double hydroxide (LDH) and tannic acid (TA) under repeated swelling cycles. Building on previous research that explored composite preparation and initial characterization, this research emphasizes the effects of cyclic swelling on wear resistance, friction behavior, and mechanical properties. Tribological tests were conducted to evaluate the coefficient of friction (COF) and wear rate before and after multiple swelling cycles, alongside tensile strength and strain measurements. The results revealed that the PVA/TA2/LDH2 composite, containing the highest additive content, exhibited the lowest wear rate of 11.52 × 10⁻⁵ mm³/Nm after 3 swelling cycles, demonstrating superior resistance to material degradation. Although PVA/TA2/LDH1 exhibited a slightly lower COF, its wear rate was higher due to reduced reinforcement. Compared to neat PVA, which showed a COF increase from 0.45 to 0.53, the PVA/LDH/TA composites retained their tribological stability, with only a marginal increase in COF and wear rate. Similarly, tensile strength of PVA/TA2/LDH2 decreased by only 11% after 3 cycles (from 33.3 MPa to 30 MPa), while neat PVA experienced a 25.5% reduction (from 30 MPa to 22.5 MPa). These findings highlight the potential of PVA/LDH/TA composites for applications in aqueous environments, offering significantly enhanced long-term performance and reliability.
