Abstract

One of the innovations in the automotive sector as an effort to increase comfort and safety for users from the middle class to the upper class is the trunk opening and closing mechanism using a microcontroller. Microcontrollers are now an innovation and are in great demand in control system applications. One of the microcontrollers that is widely used is Arduino. Arduino is very popular because it is simple to use and easy to operate according to needs. Electrical energy is the energy produced by the movement of electrons through a conductor. Electrical power is the amount of electrical energy used every second in a circuit. In its development, electronics is a branch of science and technology with the design of device applications involving electrons in various mediums (such as gases and semiconductors). Power Back Door is one of the renewable technologies in vehicles. This advanced technology works by opening and closing the vehicle's trunk door automatically. The results of this research show that the simulator functions well and according to plan. This simulator can work by detecting objects accurately. It is hoped that the implementation of this simulator can become the basis for developing a power back door system in the future.Keywords: Power Back Door, Automotive, Microcontroller, Arduino, Electrical Energy

Abstract

This study aims to analyze heat transfer on motorcycle brake pads using a specially designed temperature sensor. The background of this research is based on the high number of traffic accidents, one of which is caused by brake system failure due to overheating. Previous studies only measured heat transfer on brake pads using simple methods with limited motorcycle models, making the results less representative of current conditions. In this study, an experiment was conducted by rubbing the brake disc and brake pads at 14 rpm for 120 seconds. The results showed temperature differences (ΔT) at several points on the brake pads, which were then averaged based on the brake pad brand. The analysis revealed that AHM brake pads exhibited lower heat transfer rates and were less prone to overheating compared to other brands. Conversely, Daytona brake pads showed the highest heat transfer rate and were more susceptible to heating. These findings indicate that the selection of brake pad material significantly affects the performance of the braking system and overall riding safety. Penelitian ini bertujuan untuk menganalisis perpindahan panas pada kampas rem sepeda motor dengan menggunakan sensor suhu yang dirancang khusus. Latar belakang penelitian ini didasari oleh tingginya angka kecelakaan lalu lintas yang salah satunya disebabkan oleh kegagalan sistem pengereman akibat panas berlebih (overheating). Penelitian sebelumnya hanya mengukur perpindahan panas pada kampas rem menggunakan metode sederhana dengan objek sepeda motor yang terbatas, sehingga hasilnya kurang representatif terhadap kondisi saat ini. Pada penelitian ini, percobaan dilakukan dengan menggesekkan piringan rem dan kampas rem pada putaran 14 rpm selama 120 detik. Hasil pengukuran menunjukkan adanya perbedaan suhu (ΔT) pada setiap titik kampas rem, kemudian dihitung rata-ratanya berdasarkan merek kampas rem. Dari analisis diperoleh bahwa kampas rem merek AHM memiliki laju perpindahan panas yang lebih rendah dan bahan yang tidak mudah panas dibandingkan dengan merek lainnya. Sebaliknya, kampas rem merek Daytona memiliki laju perpindahan panas tertinggi dan bahan yang lebih mudah panas. Hasil ini mengindikasikan bahwa pemilihan material kampas rem sangat berpengaruh terhadap kinerja sistem pengereman dan keselamatan berkendara.

Abstract

This study aims to design and test a simulator of the alternating current generator starter system using a step-up dc to dc converter and a brushless direct current controller as an instructional medium. The simulator is developed to help learners understand the working principle of the alternating current generator starter system, which integrates the functions of both a starter and an alternator into a single unit. The research method employed is a technical and experimental approach, which includes needs analysis, component selection, assembly, and both electrical and mechanical testing. Testing was carried out to ensure the functionality of each part, such as increasing the voltage from 12V to 36V and regulating current through the brushless direct current controller to rotate the rotor. The results indicate that the simulator accurately replicates the operational characteristics of the alternating current generator starter system, including the relationships between voltage, current, rotor speed, and back electromotive force. Electrical stability and the simulator frame ensure the simulation runs smoothly without mechanical disruption, making it appropriate for educational and technical training purposes and offering potential for further development. Penelitian ini bertujuan untuk merancang dan menguji simulator sistem starter alternating current generator menggunakan step-up dc to dc converter dan controller brushless direct current sebagai media pembelajaran.

Abstract

This study aims to comprehensively analyze the performance implications of modifying the drive pulley inclination angle from the standard 15° to 13.8° on a KZR-type engine, specifically focusing on its effects on power, torque, and fuel consumption. This research employed an experimental method using a single Honda Vario 125 Techno FI motorcycle as the object of study. Performance data, including torque and power, were meticulously collected using a BRT Super Dyno 50 L dynamometer, while empirical tests were conducted to measure real-world speed and fuel efficiency. The results revealed a substantial enhancement in engine performance with the 13.8° modified drive pulley. Specifically, maximum torque increased by 37.3%, from 11.65 Nm to 16.00 Nm, and maximum power saw a significant rise of 57.1%, from 13.54 HP to 21.28 HP. This modification also led to a reduction in v-belt slip, indicating improved transmission efficiency. However, this performance gain was accompanied by a trade-off, as fuel consumption increased from 90 ml/km to 100 ml/km. Tujuan dari penelitian ini adalah untuk menganalisis secara komprehensif dampak perubahan sudut kemiringan drive pulley dari standar 15° menjadi 13,8° terhadap performa sepeda motor dengan mesin tipe KZR, serta mengetahui pengaruhnya terhadap daya, torsi, dan konsumsi bahan bakar. Penelitian menggunakan metode eksperimental dengan objek penelitian satu unit sepeda motor Honda Vario 125 Techno FI. Data performa, meliputi torsi dan daya, diukur secara akurat menggunakan dynamometer BRT Super Dyno 50 L, sementara pengujian empiris dilakukan untuk mengukur kecepatan dan efisiensi bahan bakar di kondisi nyata. Hasil penelitian menunjukkan bahwa penggunaan drive pulley 13,8° secara substansial meningkatkan performa mesin. Secara spesifik, torsi maksimum meningkat sebesar 37,3%, dari 11,65 Nm menjadi 16,00 Nm, dan daya maksimum mengalami kenaikan signifikan sebesar 57,1%, dari 13,54 HP menjadi 21,28 HP. Modifikasi ini juga berhasil menurunkan tingkat slip pada v-belt yang mengindikasikan efisiensi transmisi yang lebih baik. Namun, peningkatan performa ini datang dengan konsekuensi, yaitu konsumsi bahan bakar yang meningkat dari 90 ml/km menjadi 100 ml/km.
