Abstract

The main component of the injection system is the electronic control unit (ECU) functions to optimize the performance of the vehicle engine. The ECU has the functions of injection duration and ignition time as an injector and ignition controller. The purpose of the study analyzed the comparison and differences in variations in the regulation of injection duration and ignition time of injection motor engines against the power output of the engine using pertamax fuel by experimental methods. There are comparisons and differences in power and torque in each variation of the programmable ECU and standard ECU settings. The highest average power and torque results at the standard ECU setting compared to the programmable ECU setting have lower average power and torque. Due to the different injection duration and ignition time of each setting, the power and torque generated by the motorcycle engine can be higher or lower per variation of the Programmable ECU setting. In addition to the difference in power output and engine torque, it also has differences in SFC values and the average Thermis Efficiency produced varies by variation of the programmable ECU settings.

Abstract

This study aims to determine the distance and braking time on 125cc motorcycle vehicles by using two types of callipers, namely single-piston and double-piston callipers. The research method uses experimental methods. There this method will compare 2 variables to get the results of the study by sulking on SNI Braking. By varying the two callipers of different types and using the brake pressure gauge, stopwatch, and meter to find out the pressure, time, and distance when conducting the test, the results of the test are calculated by the formula of regularly changing straight motion force (GLBB) slowed down, braking force and braking efficiency formula in order to get more valid results. Based on the results of this research report, it was concluded that the 2-piston callipers are superior to the 1-piston callipers in terms of average mileage of 0.51 m (9.81 m – 9.30 m) in front wheel braking and average mileage of 0.42 m (4.63 m – 4.21 m) in rear wheel braking and average stopping time of 0.21 s (2.51 s – 2.30 s) with the average effect of braking efficiency value of 5% (57% - 52 %) on front wheel braking and the average time for 0.21 s (1.58 s – 1.37 s) with the average effect of efficiency value of 5 % (47 % - 42 %) on rear wheel braking. So that makes 2-piston callipers better used in 125 cc vehicles than 1-piston callipers in terms of braking aspects.

Abstract

In current developments, CDI ignition systems are widely used in motorcycle vehicles. This study aims to determine the effect of using variations of CDI Limiter and CDI unlimiter with spark plugs on torque, power, and fuel consumption using pertamax fuel. The research method is an experimental research method, carried out on a Vespa Strada 150 CC motorcycle. Research data obtained from tests using a dynamometer to determine the value of torque and power generated which will later be analyzed by directly observing the experimental results then drawing conclusions and determining the results of research conducted in the form of tables and diagrams, while for testing fuel consumption using measuring cup and calculating fuel consumption. Based on this report, shows that there are differences in torque, power, and fuel consumption produced. The highest torque value is found in the CDI unlimiter variation with platinum spark plugs at a rotating speed of 11000 rpm producing a torque of 7.09 Nm, while the highest power value is also found in the CDI unlimiter variation with Platinum Spark Plugs at 11000 rpm of rotating speed producing power of 10.7 HP and fuel consumption (SFC) the highest value was obtained in the CDI Limiter variation with platinum spark plugs at 11000 rpm resulting in an SFC of 0.67 L/HP.h.

Abstract

Based on the experience of automatic motorcycle users Honda Vario 150, the motorcycle has several weaknesses, but one of the weaknesses that often occurs is the slow acceleration of the motorcycle from low to medium speed. CVT transmission system (Continuously Variable Transmission) affects the slow acceleration of a motorcycle from low to medium speed. The purpose of this study is to analyze the results of testing the use of roller weights with standard weights (18 g), 16 mix standard, and 16 g to get the value of the best acceleration on a dead motorcycle c Honda Vario 150. The research method used is an experimental research method using two research methods, namely testing with a dynamometer and testing with acceleration measurements with logger pro software. The use of a standard roller weight (18 g) is the roller weight with the fastest acceleration on a Honda Vario 150 motorcycle. This is evidenced by an average acceleration of 2.98 m/s2 . While the roller weight of 16 mix standard and 16 g experienced a decrease in acceleration. For roller weight 16 mix standard, there was a decrease in acceleration of 15.44% with an average acceleration of 2.52 m/s2 . And on the 16 g roller weight, there is a decrease in acceleration of 28.86 % with an average acceleration of 2.12 m/s2.

Abstract

Condensers as the main equipment and heat exchangers in a combined cycle power plant have a major effect to determine combined cycle efficiency. The condenser is used to transform saturated steam into water which will be reused in a combined cycle power plant. To acquire high performance, the condenser requires an overhaul plan and calculated performance. In this research, to determine a good overhaul plan, the python programming language with the linear regression method is used. The python programming language aims to predict the condenser when it must be overhauled. From the results of the research, it was found that there was an increase in the value of the cleanliness factor condenser before the overhaul. From 56.69% to 57.45% after the overhaul. After using linear regression in python programming on the distribution data from 2018 which was divided into three groups of analysis, it was found that the condenser must be overhauled on August 24, 2023.
