Abstract

Penelitian ini dilakukan karena banyak nya kendaraan yang mengalami penurunan kinerja sebab dari usia pemakaian kendaraan, yang mengakibatkan konsumsi bahan bakar pada engine menjadi boros akibat dari kurang nya perawatan, sehingga proses kinerja mesin menjadi tidak sempurna. Tujuan penelitian ini untuk mengurangi konsumsi bahan bakar pada suatu kendaraan agar menjadi lebih irit dalam pemakaian bahan bakar dengan memasang Turbo Cyclone Electric, yang akan menjadi objek pada penelitian ini, yaitu Honda Mobilio tahun 2015. Metode pada penelitian ini yaitu eksperimen. Dari pengaruh penggunaan Turbo Cyclone Electric terhadap konsumsi bahan bakar pada mobil, memiliki pengaruh yang signifikan dimana thitung lebih besar dari ttabel pada taraf signifikan 5%, dimana hasil uji statistik yang di dapat adalah thitung =41 dan ttabel =12,70, maka dapat disimpulkan bahwa ada pengaruh konsumsi bahan bakar mobil dari penggunaan Turbo Cyclone Electric pada mobil.    This research was carried out because many vehicles experience a decline in performance due to the age of vehicle use, which can result in wasteful fuel combustion in the engine. This occurs as a result of lack of maintenance on the vehicle, so that the engine performance process becomes imperfect. The aim of this research is to reduce fuel consumption in a vehicle so that it becomes more fuel efficient by installing a Turbo Cyclone Electric on the vehicle that will be the object of this research, namely the 2015 Honda Mobilio. The research method in this research is experimental. The results of testing fuel consumption in this research, from the effect of using the Turbo Cyclone Electric on fuel consumption in cars, have a significant influence where tcount is greater than ttable at the 5% significance level, where the statistical test results obtained are tcount = 41 and ttable = 12.70, it can be concluded that there is an influence on car fuel consumption from using the Turbo Cyclone Electric in the car.

Abstract

This study explores the construction of a smoke machine for visualizing air movement in a wind tunnel. The device produces synthetic smoke using a flat nickel wire heating mechanism to heat liquid glycerin. During the test, three coils were selected to produces the smoke namely flat nickel wire, each with a resistance of 3.5 Ω. A power supply adapter with a 220V DC input and 24V 10A output powers the device. Glycerin liquid is used as the heating medium due to its safety and compatibility with the machine and wind tunnel equipment. The equipment heats 200 ml of glycerin, evaporating it in about 2-3 minutes to produce sufficient smoke. According to research, the device can operate for 4 minutes, allowing the observation of air movements in the wind tunnel using a slow-motion camera. Penelitian ini membahas tentang proses pembuatan alat smoke machine pada wind tunnel sebagai visualisasi aliran udara. Alat ini digunakan sebagai alat penghasil asap buatan (smoke). Peneliti merancang alat menggunakan alat pemanas tipe kawat nikel pipih dengan memanaskan cairan glycerin. Dari percobaan yang telah dilakukan peneliti memutuskan menggunakan 3 buah lilitan kawat nikel pipih dengan tahanan 3,5 Ω. Untuk arus supply menggunakan adaptor power supply dengan input 220V DC output 24V 10A dan menggunakan cairan glycerin yang akan dipanaskan, dikarenakan cairan ini aman untuk digunakan dan tidak menyebabkan kerusakan pada alat smoke machine maupun wind tunnel. Prinsip kerja alat ini yaitu memanaskan cairan glycerin sebanyak 200 ml sehingga menguap yang membutuhkan waktu sekitar 2-4 untuk menghasilkan asap yang baik dan bagus. Dari hasil penelitian alat ini dapat digunakan selama 4 menit menggunakan kamera slow motion di wind tunnel dalam proses visualisasi aliran udara.

Abstract

A novel approach was devised to optimize the stator slot semi-closed type in order improve the magnetic flux connection and minimize iron leakage in high-speed spindle drives. The concept was executed through a combination of response surface approach including the technique of finite element analysis. The primary objective of this investigation would be to provide an engineering approach which improves the functionality of stator criteria, including the stator slot geometry, coil turn per slot, and wire size. The purpose is to achieve higher flux connection and minimize iron leakage. This study presents an enhanced analytical approach that incorporates the analysis of stator flux connection, finite element calculation of flux connection, and iron leakage analysis of stator variables. The results are analyzed through the utilization of finite element computation, and their accuracy is verified through experimental measurements. The findings suggest the ideal design yields increased magnetic flux connection and reduced iron leakage in comparison to the industrial layout. The precision provided by the suggested model is confirmed through the comparison of the simulation and experimental information. In general, the percentage of errors is estimated to be around 7%.

Efisiensi sistem pengapian pada sepeda motor sangat penting untuk menunjang performa dan konsumsi bahan bakar yang optimal. Penelitian ini bertujuan menganalisis pengaruh variasi flash cable terhadap tegangan primer coil pada sepeda motor injeksi (FI). Tiga jenis lilitan flash cable yaitu 11, 16, dan 21 lilitan diuji untuk melihat peningkatan tegangan yang dihasilkan. Metode eksperimen kuantitatif digunakan dengan alat pengukuran berupa peak voltage adaptor yang dihubungkan ke multimeter digital. Hasil menunjukkan bahwa variasi panjang flash cable secara signifikan memengaruhi tegangan primer coil, di mana flash cable dengan 21 lilitan memberikan peningkatan tegangan tertinggi sebesar 261,625 V, dibandingkan dengan kondisi tanpa flash cable yang hanya mencapai 219 V. Penggunaan flash cable dapat meningkatkan efisiensi pengapian, performa, dan efisiensi bahan bakar sepeda motor FI.  The ignition system's efficiency in motorcycles is critical to support optimal performance and fuel consumption. This study aims to analyze the effect of flash cable variations on the primary tension of the coil in injection motorcycles (FI). Three types of flash cable windings, i.e., 11, 16, and 21 windings, are tested to see the increase in voltage produced. The quantitative experiment method uses a measurement tool as a peak voltage adapter connected to a digital multimeter. The results showed that the variation in the length of the flash cable significantly affected the primary voltage of the coil, where the flash cable with 21 windings provided the highest voltage increase of 261.625 V, compared to the condition without the flash cable, which only reached 219 V. Flash cable can improve the ignition efficiency, performance, and fuel efficiency of FI motorcycles.

Abstract

The local coffee farmers employ manual inspection to identify the maturity of coffee cherries that are inefficient in labor and time. Thus, the objective of this study is to develop a CNN-VGG19 algorithm model that can accurately detect the maturity image of coffee cherry samples, and classify them into: unripe, semi-ripe, ripe, and overripe categories. The proposed solution will provide local coffee farmers with an automated and more accurate classification of the quality of coffee cherries. The visual geometry group-19 was employed to increase the object recognition model performance of the proposed algorithm while maintaining higher accuracy and quicker throughput, thus increasing revenues. The images are utilized as training and test set data. They were then processed by using the feature extraction of CNN-VGG19 deep learning model, and got four coffee cherry maturity classes. The model architecture attained a 90.00 % accuracy. Furthermore, the increase in both the validation and training accuracy graph with a corresponding decrease in both the validation and training loss graph propounds that the model performance has improved.
