This research proposes a new model of overlap and helix blade shape. The overlap shape of the blades gives room to the air flow shortly after pounding the blades. Air flow direction is strived to be able to push the next blade so that the process of the turbine blade rotation becomes more effective. While the helix model is expected to produce a more efficient turbine rotation due to its multilevel shape. The wind speeds tested were 2 m / s, 4 m / s, and 6 m / s. Turbine speed rotation data retrieval is carried out at each additional time. The overlap blade has a greater angular velocity value of 9.4 rad / s at 2 m / s wind speed, 21.9 rad / s at 4 m / s wind speed, and 29.8 rad / s at 6 m / s wind speed.Turbines with multilevel helix blades have a higher level of stability compared to overlap blades. This is because there are two levels of turbine blades which have an angle difference of 600 which can receive more stable wind collisions. However, due to the smaller cross-sectional area of the helix blade turbine (ie 50% of the overlap blade) the effective impact area on the blade is also getting smaller. So that the energy that can be converted is also relatively smaller than the overlapping blade.

Solar Panel-Based Electric Scooter (E-Scooter) is an electric vehicle in the form of a scooter that uses solar panels as a source of electrical energy for charging batteries and a BLDC motor as a wheel drive. With the development of the E-Scooter, it is necessary to know how to charge the battery. The purpose of this research is to determine the type of Solar Charge Controller (SCC) that can maximize battery charging on the E-Scooter. The research method is to compare SCC MPPT and SCC PWM. The research was conducted by monitoring the output current and voltage of the solar charger controller generated by the solar panels every 10 minutes. After that the recorded data will be stored in the monitoring device's storage memory for further processing. The results of the data that have been obtained on the e-scooter using the SCC MPPT type are capable of producing a power of 9.05 W with a current value of 0.33 A and a voltage of 27.47 V. Meanwhile, the PWM type SCC is capable of producing 8.22 W of power with a current value of 0.30 A and a voltage of 27.42 V. So that the MPPT type SCC is more economical than PWM for charging when the e-scooter is not moving. For the running conditions of the MPPT type SCC e-scooter is capable of producing 7.36 W of power with a current value of 0.27 A and a voltage of 27.26 V. Meanwhile, the PWM type SCC is capable of producing a current of 6.81 W with a value of 0.25 A and a voltage 27.24 V. So that the MPPT type SCC is more efficient than PWM for charging when the e-scooter is running.

Research on the "Effect of Magnetic Field Variations on Fuel Channels on the Efficiency of Consumption and Exhaust Emissions on Gasoline Engines" focus on how magnetic fields with various forces can increase the efficiency of fuel consumption and reduce exhaust gas emissions in gasoline -fueled engines. In this study, the magnetic field was applied to the fuel channel with the aim of affecting the combustion process in the engine. The strength variations of the magnetic field used are expected to optimize fuel combustion, so that fuel consumption becomes more economical and exhaust emissions, such as oxygen (O₂), carbon monoxide (CO), carbon dioxide (Co₂), and hydrocarbons (HC), can minimized. The results showed that the application of magnetic fields has the potential to have a significant impact on engine efficiency, especially at certain rotation, which can create environmental benefits with cleaner gas emissions and reduce overall fuel consumption.

Injection molding is an important process in plastic manufacturing, especially for mini tray production that requires stability and severe accuracy. Temperature and injection time affect product quality, including material distribution and possible defects. This study aims to analyze the effect of these two parameters on the final weight of the product and determine optimal arrangements to achieve consistent quality. This study uses an experimental method with independent variables in the form of temperature and injection time, as well as the dependent variable in the form of product weight. Data is collected through testing with KT-105 injection molding machine and analyzed using Minitab 19 software to test the relationship between variables statistically. The results showed that the temperature and time of injection had a significant effect on the weight of the mini tray. Anova analysis proves a strong relationship between these two parameters, with a p-value value <0.05

This study aims to design and fabricate a speedometer cover for Yamaha Aerox and N-Max 155 motorcycles using 3D printing technology, guided by the House of Quality (HOQ) framework. The increasing consumer demand for motorcycle accessories motivated this research. A structured design process was implemented, beginning with a consumer needs analysis conducted through questionnaires and surveys to identify user expectations. These needs were systematically translated into technical requirements using the HOQ method. The design stage utilized 3D CAD modeling and 3D scanning to ensure accurate fitting to the speedometer unit, followed by prototyping using fused deposition modeling (FDM) 3D printing. The final prototype exhibited key consumer-desired attributes such as heat resistance, structural durability, and a secure fit. Results indicate that integrating the HOQ approach with digital fabrication methods effectively aligns product design with user expectations. This study demonstrates the potential for further development of customizable motorcycle accessories using a consumer-driven and technology-supported design process.

Efisiensi produksi dalam industri keramik telah menjadi fokus utama dalam beberapa tahun terakhir. Salah satu tahap krusial dalam proses produksi keramik adalah pencampuran bahan glasir, yang berdampak signifikan terhadap kualitas warna dan tekstur hasil akhir keramik. Penelitian ini bertujuan untuk meningkatkan efisiensi dan akurasi dalam proses pencampuran bahan glasir di industri keramik melalui penggunaan trafo getar sebagai penggerak mekanik. Trafo getar digunakan untuk menghasilkan getaran dengan frekuensi tinggi yang membantu mendistribusikan bahan secara lebih merata, sehingga warna dan tekstur keramik menjadi lebih konsisten. Sistem pengendali yang diterapkan menggunakan dimmer untuk mengatur sudut picu yang mempengaruhi frekuensi getaran dan arus yang dialirkan ke trafo. Pengujian dilakukan dengan variasi sudut picu untuk mengukur pengaruhnya terhadap kecepatan getaran dan arus listrik. Hasil penelitian menunjukkan bahwa peningkatan sudut picu berbanding lurus dengan kenaikan frekuensi dan arus, yang berimplikasi pada variasi kecepatan getaran dari sangat lambat hingga sangat cepat. Metode ini diharapkan dapat menjadi solusi inovatif untuk meningkatkan kualitas dan efisiensi dalam produksi keramik. Dibandingkan metode manual, alat ini meningkatkan efisiensi waktu hingga 40% dan mengurangi biaya operasional sebesar 30% dalam jangka panjang.

This study investigates the impact of solar charge controller (SCC) type on battery charging in solar-powered electric scooters (e-scooters). The research compared maximum power point tracking (MPPT) and pulse width modulation (PWM) controllers by monitoring average output power, current, and voltage every 10 minutes. Results showed that under stationary conditions, MPPT controllers delivered higher efficiency, generating 5.87 W of power compared to PWM's 5.05 W. This advantage persisted even during scooter operation, with MPPT controllers producing 4.91 W versus PWM's 4.31 W. Overall, the findings demonstrate that MPPT SCCs offer a more efficient solution for charging e-scooter batteries.
