Abstract

The use of Honda Beat motorcycles in 2016 is still quite dominant among two-wheeled vehicle users. One of the efforts to improve vehicle performance is done by replacing standard spark plugs with racing spark plugs, installing groundstraps on coil cables, and modifying the ECU remap using the Juken 5 ECU with a limiter increased to 10,000 RPM. Groundstraps play a role in stabilizing the flow of electric current in the vehicle's electrical system, so that it can increase ignition efficiency and produce stronger and more consistent sparks on the spark plugs. The purpose of this study was to determine the effect on the performance of Honda Beat FI motorcycles that use racing spark plugs, groundstraps on coil cables and ECU remaps. This study needs to be done, so that motorcycle users can improve vehicle performance by adding groundstraps to the high-voltage coil cables. This study uses an experimental method. Dynotest is used to determine the resulting performance. The first step taken, testing, tuning and continued testing. The results showed that standard conditions produce a torque of 6.97 N.m and a power of 6.3 HP; The condition without a groundstrap produces 6.98 N.m of torque and 6.9 HP of power; while the condition with a groundstrap produces 6.99 N.m of torque and 6.4 HP of power. The torque generated by testing using a groundstrap increased compared to standard conditions, and power output also increased. Therefore, the use of a groundstrap and ECU remap affects the motorcycle's torque and power performance. Torque is essential for acceleration and climbing, while power influences top speed.

Abstract

This study aims to test the effect of the combination of bore up, variations of racing spark plugs, and free flow exhaust silencers on engine power and torque. The method used in this study is an experimental method with a quantitative approach. Changing the bore up piston diameter from 54 mm to 62 mm makes 135 cc to 177 cc and added by varying the racing spark plugs namely iridium, platinum, and the length of the free flow exhaust silencer 180 mm and 300 mm using a dynotest test. The results of the bore up of standard spark plugs and standard exhaust increased torque by 15.06 Nm and power to 12.47 kW. The combination of bore up with iridium spark plugs and 180 mm silencers produced the highest performance, namely 16.39 Nm of torque increased by 60.50% and 15.58 kW of power increased by 100%. Meanwhile, the combination with platinum spark plugs and 300 mm silencers produced 16.04 Nm of torque and 14.61 kW of power. These findings indicate that a bore-up configuration with iridium spark plugs and a 180 mm silencer is the most optimal combination for improving engine performance.

Abstract

This study aims to: 1) evaluate the feasibility of the teaching media developed to support learning on the topic of wiper and washer systems; and 2) examine the extent to which the media can improve student learning outcomes. This research uses a Research and Development (R&D) approach with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model which includes five stages, namely analysis, design, development, implementation, and evaluation. The research design used was One Group Pretest-Posttest. The research participants were students of class XI of Automotive Light Vehicle Engineering (TKRO) at SMK Dr. Sutomo Temanggung. The research subjects consisted of 29 students in grade XI TKRO 3 who acted as a control group and 28 students in grade XI TKRO 2 as an experimental group. Based on the results of validation by material experts and media experts, the wiper and washer system teaching media developed was declared to meet the eligibility criteria to be applied in the learning process. The measurement of learning outcome improvement is carried out through pre-test and post-test, then analyzed using the N-Gain formula. The results of the analysis showed that both the experimental group and the control group experienced an increase in learning outcomes at almost the same rate. The N-Gain value in the experimental class reached 0.679 or equivalent to 67% which was included in the category of "moderate" improvement. Meanwhile, the control class obtained an N-Gain value of 0.678 or 67% which is also included in the "moderate" improvement category. These findings indicate that the props of the wiper and washer systems are feasible and quite effective to be used in learning automotive engineering.
