Abstract

Vocational education has a real goal, which is to prepare students to enter the world of work. The aims of this study were (1) to find out the planning stages of Macromedia flash-based learning media, and (2) to find out the feasibility of Macromedia flash-based learning media in simulation and digital communication subjects in vocational schools. This type of research is developed with the model used the V model or commonly called the verification and validation model. The system development process includes requirements analysis, requirements standards, design specifications, and program specifications. Based on the test results, it is known that the learning media based on Macromedia flash on simulation and digital communication subjects in SMKs that have been developed are suitable for use as learning media in SMKs. The average score obtained as a whole aspect of media experts was 3.58 in the very good category, material experts with a score of 3.62 in the very good category, and the student response score to Macromedia flash-based learning media was 3.89 very well. good category. good. So learning media based on Macromedia Flash 8 shows very feasible to be used as a learning medium in simulation and digital communication subjects in Vocational High Schools.Keywords: Macromedia Flash, Vocational Learning, Simulation, Digital CommunicationDOI: http://dx.doi.org/10.23960/jpf.v10.n2.202205

Abstract

This study analyzes the comparison of the power factor on the compressor motor type electromotor 15 kw (30 Bar/High pressure) at PT. Natural gas is a means of work. The power factor is the power losses generated by the electricity in the compressor motor, the power factor is also useful for limiting large power expenditures and the power factor or cos phi has a ratio between active power and apparent power. The results of this study indicate that the comparison of the power factor on the load of the 15 kw electromotor compressor motor at the initial start of the motor can be seen manually counting data and graphs every week. In the first week of total, 0.85 compared to the data for the second week, third week, and fourth week.
