Abstract

Sumber Energi Terbarukan (EBT) harus lah dapat dimanfaatkan dengan baik, sebagai upaya untuk mengurangi krisis energi dan dampak polusi. Salah satunya dengan mengembangkan Pembangkit Listrik Tenaga Mikro Hidro (PLTMH). Jenis turbin yang yang berpotensi untuk pembuatan PLTMH pada sungai-sungai di Indonesia yaitu turbin ulir. Tujuan dari penilitian ini yaitu untuk mengetahui performa dari turbin ulir dengan menggunakan variasi sudut kemiringan poros turbin dengan variasi sudutnya yaitu 32°, 36°, 40° dan 44°. Hasil penilitian ini menunjukan bahwa sudut kemiringan poros turbin dapat mempengaruhi kinerja turbin ulir. Hasi yang diperoleh menunujukan kemiringan poros turbin dengan sudut 32° mendapatkan performa yang maksimal dengan nilai torsi sebesar 0,930 Nm, daya yang dihasilkan yaitu 33,085 Watt, dan efisiensinya yaitu 87%. Untuk hasil terendah didapatkan pada variasi sudut 44° dengan torsi yang diahsilkan yaitu 0,702 Nm , daya sebesar 23,034 Watt dan efisiensinya 51%.

Abstract

At this time, motorcycles, especially performance, are very important, where many young people now really want to increase the performance of their motorbikes. This study examines the difference in performance between the use of standard exhaust and racing exhaust on a Supra GTR K56 150 cc motorcycle. The experimental method is used by using a dynometer to measure the power and torque of the vehicle. The results showed that the use of racing exhaust resulted in an increase in power of 1.86 hp at 9000 rpm and a widening of the peak power at high engine speed. In addition, the racing exhaust also provides more controlled acceleration and a smoother power increase compared to the standard exhaust. Even though the performance increase is not significant, changing the exhaust to a racing exhaust can give a different response when the vehicle is used at high engine speed. In conclusion, the use of racing exhaust on a 150 cc Supra GTR motorcycle can produce higher performance and better response compared to the standard factory default exhaust.

Abstract

The automotive industry is experiencing a very rapid development of science and technology. CVT (Continously Variable Transmission) is a transmission that is able to change the effective gear ratio smoothly or without pause so it is often called a gearless transmission. The compressive force of the centrifugal roller is influenced by the weight of the roller and the rotation of the engine itself, the heavier the roller, the greater the force to push the movable drive face on the drive pulley which results in a smaller pulley diameter. The purpose of this study is to determine the difference in power and torque generated from the comparison of the weight of standard rollers with racing rollers on a 2015 Honda Beat PGM-Fi motorcycle. In this study using a variation of standard ballast type and 11 gram racing ballast type. The research was conducted by experimental method or testing with the help of dyno tools. The results of research on the effect of the weight of standard rollers and racing rollers that produce maximum power at 6000 rpm with a power of 7.22 Hp using an 11 gram roller (racing). On a 13 gram roller (standard) the maximum power is generated at 7000 rpm with a power of 6.68 Hp. The torque produced on the 13 gram roller (standard) produces maximum torque at 6000 rpm with a torque result of 7.94 Nm. While the 11 gram roller (racing) also produces maximum torque at 6000 rpm with a torque of 8.57 Nm. By replacing the 13 gram roller weight (standard) with a lighter roller weight or 11 gram roller (racing) affects the power and torque of the 2015 Honda Beat Pgm-Fi motorcycle. The power and torque of the motorcycle are much better and more dominating by using a roller weight of 11 grams (racing).

Abstract

This study aims to investigate the effect of using Pertalite fuel on the performance of power, torque and fuel consumption on motorcycles with automatic transmission. The experimental method used by collecting data shows the performance of motorcycles using Pertalite fuel and comparing them to motorcycles using lower octane fuel. Various parameters such as maximum power, maximum torque and fuel consumption were measured and compared between the two groups. The results showed that the use of Pertalite fuel had a positive effect on power performance on automatic transmission motorcycles. The maximum power produced by an engine using Pertalite is higher than that of an engine using low octane fuel. In addition, the use of Pertalite also contributes to an increase in engine torque at certain engine speeds. However, in terms of fuel consumption, although the use of Pertalite has the potential to improve fuel efficiency, the results of this study show significant variations depending on the operating conditions and settings of the motorcycle. This study provides insight into the effect of using Pertalite fuel on the performance of power, torque, and fuel consumption on motorcycles with automatic transmission. The implications of this research can be used by motorcycle manufacturers and consumers in considering the use of fuel according to their needs and preferences.

Abstract

The purpose of this study is to analyze the mechanical response of a piston in an engine with different piston materials. The piston materials used are Aluminium AA356.0-F, 2618-T61 (SS), and 4032-T6. The analysis is conducted using the Solidworks software, which allows for simulation and evaluation of the piston's performance under operational conditions. Stress, displacement, and strain analysis of a piston using different piston materials (Aluminium AA356.0-F, 2618-T61 (SS), 4032-T6) conducted using Solidworks. Objective: gaining insights into the relative performance of each piston material and selecting the optimal material for engine applications. A 3D model of a piston is created using Solidworks, followed by the selection of three different materials: Aluminium AA356.0-F, 2618-T61 (SS), and 4032-T6. Simulation analysis is performed to obtain the stress, displacement, and strain for each variation of the piston material. The results are then analyzed and compared to determine the relative performance of each piston material. Analysis using Solidworks revealed significant variations in stress, displacement, and strain in pistons with Aluminium AA356.0-F, 2618-T61 (SS), and 4032-T6 materials. The 2618-T61 (SS) material exhibited higher stress, while the 4032-T6 material showed lower displacement. The selection of piston materials should consider factors such as strength, deformability, and optimal performance. The analysis using Solidworks showed significant differences in stress, displacement, and strain in pistons with varying piston materials. The selection of piston materials should consider a balance between strength and deformability for optimal performance.
