Abstract

This study aims to develop Android-based learning media to improve students' abilities regarding the reduction type starter motor system and to determine the acquisition of learning motivation. The method used is pre-experimental design in the form of one-group pretest-posttest, while media development uses the ADDIE method. The population of this study were students who contracted electricity courses. The results of this study indicate an increase in the learning outcomes of the Pre-Test and Post-Test which is significant with the acquisition of the significance test using the t test with a significance value of 0.000, this increase is due to the use of android-based learning media that has been made. So that this learning media has a good impact on increasing students' insight in using technology, especially Android for learning uses. In addition, the students' learning motivation on average is in the category motivated by this media.

Abstract

The internal combustion engine is a gasoline-powered internal combustion engine that is widely used in the world of transportation. Therefore, everyone is starting to think about developing alternative fuels that are fuel efficient, easy to upgrade, and better in terms of emissions. Vehicles with electric motors are one of the right solutions because they are more environmentally friendly and do not cause pollution when used. In this study, we will discuss the performance of the brushless DC electric motor that is applied to the Go-kart based on the voltage, current, and electrical power that occurs. The method used is measurement using software and experimental simulations. Based on the test results using Votol_V3 Voltage, current, power, and rotation per minute (rpm) have a relationship, the higher the rpm on the mid-drive type electric motor, the greater the current and power required.

Abstract

Rapid advancements in hybrid vehicle technology demand significant adjustments in vocational education to equip students with relevant competencies. This study investigates the effectiveness of a hybrid motorcycle prototype as an innovative learning media to improve student learning outcomes in vocational automotive education. Employing a pre-experimental one-group pretest-post-test design, the research involved 30 Grade XI Automotive Engineering students at SMK Negeri 1 Cisarua. Participants underwent a pretest, followed by four prototype-based learning sessions, and a post-test. Data were analysed using descriptive statistics, paired-samples t-test, and normalized gain (g). Results demonstrated a substantial improvement in learning outcomes, with the mean score increasing from 58.5 to 82.67 (mean gain = 24.17 points; t(29) = 8.805, p < 0.001; Cohen's d = 1.61), indicating a very large effect size. The normalized gain of 0.55 suggests medium effectiveness based on Hake's classification. Furthermore, 90.0% (27/30) of students achieved scores ≥75 post-intervention, compared to 23.3% (7/30) beforehand. Aligning with Edgar Dale’s Cone of Experience, these findings highlight that direct, hands-on engagement enhances comprehension and retention. The study concludes that hybrid motorcycle prototypes offer a cost-effective, practical, and scalable solution to bridge the theory-practice gap in vocational automotive education, especially in motorcycle-dominant contexts. Recommendations include integrating prototype-based learning into the Merdeka Curriculum and expanding its application to other technical domains.

Abstract

The stability of alternator output voltage is important for maintaining modern diesel vehicle electrical systems, because additional loads such as headlights, cabin cooling, and audio systems can increase current demand and affect charging voltage. This study aims to analyze alternator output voltage under variations of electrical load on a vehicle with a 4V21 Euro 4 diesel engine. A field experiment was conducted on a vehicle with a 24-volt electrical system and the engine operating at idle speed. Data were collected using a scanner under three load conditions: no load at 0 W, medium load at 150 W, and full load with a reference power of 1,110 W. Each condition was tested five times, with a data collection duration of 20 minutes per test, conducted once per day for five days. The main parameter observed was alternator output voltage, while engine RPM and coolant temperature were recorded as supporting data. The results showed that the average alternator output voltage was 28.3 V under no-load conditions, 27.8 V under medium-load conditions, and 27.7 V under full-load conditions. The total voltage drop from no load to full load was 0.6 V. Engine RPM remained at an average of 651 rpm, and coolant temperature remained at 83.1°C. These results indicate that increasing electrical load reduces alternator output voltage; however, the decrease was relatively small, and the lowest voltage still met the operating range of the 24-volt charging system, indicating that the charging system operated properly under the tested load variations.

Abstract

Starting performance in diesel engines is influenced by the battery’s ability to maintain voltage when the starter motor draws a high initial current. Excessive voltage drop can reduce cranking capability and affect the initial combustion process. This study aimed to analyze the effect of battery voltage drop on starting time in a Mitsubishi Triton equipped with a 4N15 diesel engine. The research used a field experimental method conducted directly on a vehicle with a 12-volt electrical system. Data were collected using a battery tester, scanner, and stopwatch through five tests consisting of three tests under normal operating conditions at 71–75 °C, one test under cold-engine conditions at 29 °C, and one test under hot-engine conditions at 89 °C. The main parameters observed were battery voltage drop and starting time. The results showed that normal operating conditions produced an average voltage drop of 3.25 V with an average starting time of 2.06 s. Cold-engine conditions at 29 °C produced the highest voltage drop of 4.23 V, while hot-engine conditions at 89 °C produced the lowest voltage drop of 3.08 V. The findings indicate that starting performance is influenced by voltage drop, battery condition, internal resistance, and CCA value. This study concludes that starting system analysis should consider voltage drop, minimum voltage during starting, and battery condition to obtain a more accurate analysis of starting performance.
