This paper discusses the development of simulators as instructional media for learning Electronic Spark Advance System in vehicle technology and its advisability. Simulators were developed to assist students in learning the skills and practical knowledge of the electronic ignition system in vehicle engine. The simulator was developed by applying 10 development stages. Development stages included: analyzing the problems, needs analysis, product design, design implementation, expert assessment, limited testing (small classes), product revisions, large usage / class testing, product revisions, and get suitable product. The development result was a replica of ESA system separated from vehicle system. The ignition system components were arranged on the acrylic board, so it can be used by the students safely and easily for: (1) identifying components, (2) inspect components, (3) inspect ignition circuit, (4) conducting ignition system adjusting, and (5) simulating ignition system. Based on the material and learning media aspects with the results of limited trials as well as usage trials show that the developed ESA's electronic ignition system simulator was suitable to use, so it can help students to learn and practice skills related to maintenance jobs and repair ESA's electronic ignition system more easily.
The increase of transportation facility needs raises a problems, especially pollution caused by motor vehicle exhaust that directly affects the decline of air function. Consequently, it is needed an effort to build alternative technologies and eco-friendly vehicles as transportation, in order to reduce the negative impact of exhaust emissions from fossil-fueled vehicles. This research was conducted to design and improve energy-saving and eco-friendly product that can be utilized as transportation. Accordingly, to improve the design of energy-saving and environmentally friendly vehicles, this research is conducted using research and development, for 5 years, starting in 2017 until 2021. Based on a survey towards 327 people that spread across major cities in Indonesia, the result reveals that the design of energy-saving and environmentally friendly vehicles required is a multi-purpose vehicle (multi-purpose vehicle / MPV). By considering the aspect of energy consumption and its impact on the environment, then the concept to improve is city car vehicle concept with 2 seats capacity plus baggage which is able to carry load of 60 kg. The selected vehicle specifications includes 2200 mm long dimension, 1800 mm width, 1700 mm height, 160 mm clearance ground, 1000 cc engine capacity, and 2 x 3000 W motor capacity.
The Covid19 pandemic that has hit the world requires educational media innovations that are portable, lightweight, and easy to operate for online learning purposes. This study aims to develop learning media for students of the Light Vehicle Engineering Vocational School on the topic of a 2 stroke engine using a engine model made using 3D printing technology with Polylactic Acid as the base material. This is carried out to develop media to support teachers of related subjects in the implementation of online learning. This study uses the Design and Development (DD Research) method which consists of identifying the problem, describing the objectives, design and development, testing, evaluating and finally communicating the results. Data analysis was carried out quantitatively and qualitatively to explain the obtained results. The checklist evaluation was performed to assess the produced learning media. The results indicated that the utilization of 3D print to create lightweight, portable and representable learning media has been successfully achieved. The constructed learning media is aimed to be utilized to explain the competency of two-strokes engine in a distance learning.
This study implemented the Problem Based Learning learning model to increase the students’ activeness and learning outcomes in the conventional fuel system competency in class XI TKRA SMK Nasional Berbah. A Classroom Action Research (PTK) with Kurt Lewin's model was conducted, and the data were collected using observation, tests, and documentation. The indicator of the success of this study is if more than 75% of students are active and 75% of students reach the minimum score criteria (75). The participants of this study were 32 students of class XI. The results showed that the application of PBL able to increase the students’ activeness and learning outcomes on the competence to understand the conventional gasoline fuel system. This can be seen from: (1) an increase in positive activities (activities that support the implementation of the teaching and learning process) and a decrease in negative activities (activities that interfere with the implementation of the teaching and learning process) in each cycle. Positive activity in cycle I was 51% and cycle II was 76%; (2) there is an increase in the class average and students' learning completeness. The class average in cycle I was 71 and cycle II was 78. Meanwhile, students' learning completeness in cycle I was 43.75%, cycle II was 84.37%.
This study aims to determine: (1) the material needed by students in the Basic Practice of Electronic Control Systems in the automotive field, (2) the design of the Basic Electronic Control System Training Kit in the automotive field, (3) the results of the development of the Basic Electronic Control System training kit in the automotive field., (4) eligibility of the basic training kit for the Electronic Control System in the automotive sector, and (5) users responses to the development results of the Basic Electronic Control System training kit. This study uses the research and development (RND) method. The research was carried out in 5 stages, namely: (1) the needs analysis stage, (2) the product design stage, (3) the product development stage, (4) the product use implementation stage, and (5) the product evaluation stage. Retrieval of data using documentation and questionnaires. The results showed that: (1) The materials needed by students in the basic practice of automotive electronic control systems include: understanding the use of simulation software, functions, arrays and looping on Arduino, serial communication, use of LCDs, use of interrupts, use of analog to digital converters, infrared sensor, ultrasonic sensor, pulse width modulation, lookup table function and EEPROM data writing, and arduino applications in the automotive sector; (2) The development product of the training kit is in the form of educational props containing parts of the power supply system, various kinds of input variations, the process system with Arduino Uno, and the output section in the form of lamps, buzzers, electric motors, solenoids, 7 segment displays, LCD, relays, and driver transistor. The model is packaged in a box for individual or group learning of 2-3 people; (3) The developed training kit was declared very feasible according to media experts and material experts; (4) The developed training kit received a positive response from users/students.
