Abstract

Vehicles are the main thing in supporting daily activities. Currently, motorized vehicles are a necessity for the community. This increase in vehicle volume leads to an increase in air pollution due to exhaust emissions. The use of low-octane fuel will affect emissions and overall motor performance. One way to increase octane number is to give octane booster. This research was conducted to see the impact of adding octane booster on exhaust emissions. Exhaust emission tests are carried out to see the value of CO, CO2 and HC. In its implementation, the author uses a Megapro PGM-FI motorcycle with 150 cc. The test results resulted in the lowest CO content of 0.19% in pure pertalite fuel, the lowest CO2 of 3.10% in the addition of 3 ml octane booster, and the lowest HC of 213 ppm in the addition of 7 ml octane booster. While the highest CO content was 0.23% in the addition of 7 ml octane booster, the highest CO2 of 3.10% in the addition of 7 ml octane booster and in pure pertalite fuel, and the highest HC of 247 ppm in pure pertalite fuel.

Abstract

Based on observations from motorcycle drivers with automatic transmissions, there are several commonly criticized complaints about the lack of responsiveness. There are many ways to improve motorcycle performance. One of them is to change the contact angle inclination of the primary he pulley of the continuously variable transmission (CVT) and change the mass of the pulley accordingly. The method used in this study is an experimental research method. This method works by directly testing the effect of one variable on another. The purpose of this study is to investigate the effect of varying primary pulley tilt on power, torque, slip ratio and fuel consumption of a 110cc bike when the primary pulley contact angle and roller mass tilt are varied. That's it. The primary pulleys have contact angles of 13.5° and 14°, and pulley masses of 13 and 15 grams. The subject of this study is a Honda Beat PGM-FI 110cc bike with an engine speed of 2000-4000 rpm. 500rpm According to the results of the studies conducted, a 13.5° primary roll and a 13 gram roll achieved the best results in all tests. Maximum torque is 24.95Nm at 2000rpm and maximum power is 8.0hp at 2500rpm.

Abstract

Motorcycles are automotive products that are widely used today. One of the components is injection as part of the fuel supply in the engine equipped with a filter. The filter serves to filter the air needed for the combustion process. The purpose of this study is to determine the effect of filter type on motorcycle engine performance. The study was conducted using experimental methods on Honda Beat Injection motorcycles. There are two types of air filters that will be tested, namely standard filters and racing filters. The experiment was carried out using a dyno test machine to obtain data directly according to the resulting engine speed. The speed of the engine and the rotation of the roller of the dynamometer are measured with a tachometer. The results of these calculations are presented in the form of tables and graphs and analyzed in accordance with existing theories. The results showed the type of air filter in the injection system, affecting the performance of the motorcycle engine on the power and torque produced. The difference in power and torque obtained after using the two types of filters is different due to the large difference in density of the filter layer material, which has an influence on the air sucked into the combustion chamber. The larger the pores of the filter layer, it will affect the air sucked into the combustion chamber and the size of dirt particles that can be filtered.

Abstract

This research was conducted to determine the effect or impact of variations in the size of a standard piston diameter (52 ML) with a piston with a diameter of 58 ML on a Yamaha Mio motorbike using a dyno test. The results we got from the dyno test, the power or horsepower (HP) produced from a motorbike with a standard 52 ML piston size is 7.44 HP at Rpm 7000 and a torque of 8.72 Nm. Meanwhile, the modified motor with a 58 ML piston produces 11.37 HP at 7000 Rpm and 11.10 Nm of torque. And it can be concluded that motors with factory original standard pistons measuring 52 ML have much lower torque and power than modified pistons measuring 58 ML and the fuel consumption of motors with modified pistons will be more or more wasteful.

Abstract

Analog Switch Off (ASO) or migration program from analog television to digital television is a program issued by the Ministry of Communication and Informatics in Indonesia. Some people provide different responses and opinions on YouTube comments about ASO. There are those who give positive or neutral comments. However, there were also those who gave negative comments. Sentiment analysis is a process that is carried out automatically in studying, retrieving, and processing textual data to obtain information and see responses or opinions about an issue or object towards positive, neutral or negative opinions. Thus sentiment analysis can be used as a reference in making organizational decisions, improving a service, or as a review of a product. Sentiment analysis was performed using word embedding with Word2Vec, and sentiment classification using the Long Short-Term Memory (LSTM) method. The results of the evaluation test are 92% accuracy, 92% precision, 92% recall, and 92% f1-score.

Abstract

The obstacle faced by PT Alis Jaya Ciptatama is that the production process carried out in 2022 still has many product defects. For this reason, it is necessary to improve the quality of the product. In this case the method used is the Six Sigma method as a quality improvement tool. The results of analysis using Pareto diagrams obtained the highest type of defect with a percentage of 38.2%, and there are three elements that influence this type of defect, namely human, machine and material elements. Through DMAI analysis, the company's average sigma value of 2.70 is still far from the company's expectations of 6, with a Defect Por Million Opportunities (DPMO) of 115362.894. This value is the most critical failure mode so it needs to be repaired. The proposed improvement is by implementing 5S and providing Standard Operating Procedures (SOP) so that operators work in accordance with operational standards in the mill 1 work area. Then a comparison is made between before and having been given the SOP, so the DPMO value is 72,666 and the sigma value is increased by 0.53.
