Abstract

The development of the learning model aimed to create learning conditions that facilitate students to be active and enjoy every learning process so that the students can optimize their achievement. One of the support tools to create an ideal learning atmosphere was learning media. The aimed of this study were to understand the impact of audio-visual media in seizing picture subject between two groups of students. This research applied Research and Development (R&D) approach. The participants consist of 2 lecturers with media expertise, 2 teachers, and 34 students of the X grade students of Light Vehicle Engineering who were selected randomly. The finding showed that there was a significant difference in the learning result. The experiment group that used audio-visual media achieved 83,24% (very high categories), while the control group that used written material achieved 49,43% (adequate-category). Based on the result above, it can be concluded that audio-visual media can improve students' competency in seizing pictures subject.

Abstract

Radiator is one of the engine cooling system components that has leakage problems due to corrosion. The leakage in the cooling system can cause bad effects namely overheating. This study aims to find out the effect of sodium chromate inhibitors (Na2CrO4) can reduce the corrosion rate of car radiator components and find out the type of corrosion that occurs in car radiator components in aquades environment. The research method used is a real experiment. The corrosion testing was conducted by specimens immersing from aluminum radiators. The specimen was immersed in distilled water solution with variations in the addition of sodium chromate inhibitors of 0%, 0.3%, 0.5% and 0.7%. The micro photo testing used an optical microscope to determine the type of corrosion. The analysis in this study is descriptive statistical analysis. The results of this study indicated of the corrosion rate of aluminum in an aquades environment without inhibitors is 0.0084 mmpy. Meanwhile the corrosion rate of aluminum decreased with the addition of sodium chromate inhibitors (0.3% by 0.0053 mmpy, 0.5% by 0.0051 mmpy and 0.7% by 0.0043 mmpy). Thus the use of sodium chromate inhibitors can extend the life / time of using aluminum radiators. While the type of corrosion that occurs is pitting corrosion.

Abstract

There are many ways that can be done to reduce the problem of fuel scarcity due to the increasing number of motorcycle usage, one of which is to make engine performance more efficient by adding catalysts and additives to the fuel used. Broquet is a catalyst product and Eco Racing is a fuel additive product that works to improve the combustion reaction process and its quality. This study aims to determine the effect of using Broquet and Eco Racing on engine performance including torque and power on a pertalite 4-stroke engine type motor and to determine the effectiveness of the product in improving engine performance. This research is using experimental method. Torque and power at the beginning of 4500 rpm engine speed testing with Broquet and Eco Racing has increased and then at the next engine speed gradually decreases. The use of Broquet and Eco Racing in pertalite influences engine performance and the use of Broquet has more effectiveness in improving engine performance at the start of engine rotation compared to Eco Racing. Keywords: Broquet, Eco Racing, Motorcycle engine performance.

Abstract

This research was carried out based on the results of observations in the vocational theory learning process, there were several obstacles faced, There are several obstacles, namely, 1) the methods used are lectures and discussions that are less than optimal; 2) students are less enthusiastic in learning the material because the media used by the teacher is in the form of power points and softfile modules; 3) It is not possible to use power point media and module softfiles to operate randomly and freely in adjusting the selection of the material pages you want to learn. The research objectives of this research are (1) develop Adobe Flash CS6-based learning media in Vocational Theory subjects,(2) analyze the feasibility and practicality of learning media,(3) analyze the effectiveness of using learning media. Research on the development of learning media based on Adobe Flash CS 6 using the ADDIE development model. The data collection tool for the feasibility of learning media uses media experts. Media practicality data using assessment questionnaires by teachers and students. In the results of this study, Adobe Flash CS 6 can be integrated with server side scripting such as CGI, ASP and PHP to create beautiful database web applications. In addition, it can also be used to make short films or cartoons, presentations, advertisements or web banners, logo animations.
