Abstract

Transportasi yang marak digunakan di indonesia adalah kendaraan berupa motor dan mobil, sekaligus pula ikut meningkatnya ketergantungan akan konsumsi bahan bakar minyak (BBM). Salah satu sumber energi yang bersifat renewable yang dapat dimanfaatkan adalah etanol yang asalnya dari tumbuhan jagung, gandum, dan yang lainnya. Uap etanol di gunakan untuk penambahan bahan bakar minyak untuk membantu kinerja mesin motor. Dalam penelitian ini saya menggunakan uap etanol sebagai campuran bahan bakar motor dan menguapkan etanol tersebut dengan suhu 400C dan di campur 3 jenis bahan bakar premium pertalite dan pertamax. Temperatur uap etanol pada penggunaan bahan bakar minyak terhadap performa dan efisiensi sepeda motor 4 langkah dengan menggunakan variasi temperatur sebesar 400C, cara kinerja uap etanol dengan bukaan full dimasukan melalui intake manifold. Setelah melakukan pengujian didapatlah hasil bahwa daya terbaik didapatkan dari tambahan uap etanol dari 3 jenis bahan bakar tersebut. Performa mesin sepeda motor yang diujikan sehingga mampu meningkatkan tenaga motor dari horsepower 28,6 menjadi 29,1 dan torque dari 29,56 menjadi 29,70 untuk bahan bakar premium, dan pertalite hp30,9 menjadi 31,0 dan torque dari 31.46 menjadi 32,12 pertamax juga meningkat dengan suhu pemanas dari horsepower 30,8 menjadi 31,0 dan torque dari 31.50 menjadi 31,76.

Abstract

Everyone uses transportation as a means of getting to different locations. There are three categories for the actual modes of transportation: air, sea, and land. People typically use ground transportation, such buses, cars, and bicycles, for daily errands and commutes to the office since these modes of transportation are more convenient and quick to use. The electric bicycle is one of the vehicles that is currently being developed. The development of electric bicycles is necessary since they are simple and comparatively inexpensive to produce. Naturally, an electric bicycle needs a motor to propel it. A DC motor needs a voltage that enters the field coil in the same direction in order to generate mechanical energy. Electromotive force is produced by the armature coil while magnetic force is produced by the field coil. When the armature coil current interacts with the magnetic field, it produces the torque (T) that powers the motor. A DC motor has windings, and the quantity of windings in the motor can change its torque and output. The author of this study employs a DC motor, and alterations are planned to the windings through both an increase and a decrease in winding count. The objective is to ascertain how a 250W electric motor's torque and power are affected by the number of windings. According to the study's findings, the torque and power obtained at the start of the standard winding test were 0.55 and 5.7, respectively, when the RPM reached 100.4. When the rpm hits 77.8, adding coils results in a torque of 0.55 and a power of 4. When the rpm reaches 131.3 and the torque is 5.5, the power is 7.5 after the coils are reduced. Thus, the rpm and power generated decrease with the number of windings. Both the resulting rpm and the power released are inversely proportional to the reduced winding.

Abstract

Objective: This study aims to investigate the effect of variations in the number of windings on torque and power output in a 250 W DC motor applied to electric bicycle propulsion, considering the growing demand for efficient, low-cost, and environmentally friendly ground transportation. Method: An experimental approach was employed by modifying the armature windings of a DC motor through both increasing and decreasing the number of coils. Motor performance was evaluated by measuring rotational speed (RPM), torque, and output power under standard winding conditions, additional windings, and reduced windings. Results: The standard winding configuration produced a torque of 0.55 Nm and power of 5.7 W at 100.4 RPM. Increasing the number of windings resulted in a torque of 0.55 Nm and reduced power of 4 W at 77.8 RPM. Conversely, reducing the windings increased rotational speed to 131.3 RPM, yielding a torque of 5.5 Nm and power of 7.5 W. The findings indicate that increased windings reduce RPM and power, while reduced windings enhance RPM and power output. Novelty: This study provides empirical evidence on how winding modification directly influences DC motor performance in electric bicycles, offering practical insights for optimizing motor design through winding configuration adjustments.

Abstract

Pump is a device used to increase pressure to flow fluid or something in the form of liquid from one place to another or from a low surface to a high surface. High pressure is exerted through the medium by imparting energy to the displaced fluid, converting mechanical energy to kinetic energy. The mechanical energy of the pump is used to increase the speed, pressure or height of the fluid. Therefore making a pump prototype by making different impeller lengths, whether it can affect the resulting flow discharge output or not. So that in the future we can conduct experiments to make an impeller which is more effective in producing a larger water discharge.
