Automatic water filling and capping machine trainer kit programmable logic controller controller prototype for vocational high school learning validity

Abstract

The purpose of this article is to find out validity level PLC controlled automatic water filling and capping machine as trainer kit for learning in industry automation competence expertise in vocational high school. Research type used in this research is research and development (R&D) according to Robert Maribe Branch. carried out steps are; Analyze, Design, Develop, Implement, and Evaluate. Instrument used is questionnaire and observation sheet. Collected data is analyzed descriptively. Research result shown that validation toward automatic water filling and capping machine prototype as trainer kit for PC practical learning in vocational high school which done by media expert, material expert, and student shown result in very satisfactory category, indicated by: (1) media experts give average score 87.5% (very satisfactory); (2) material experts give average score of 86,9% (very satisfactory); and (3) student give average score of 95,3% (Very Good)

Developing a Trainer Model of Audio Amplifier Troubleshooting in Vocational High Schools

“…The product trial design was conducted to determine the students' responses after using the learning media and to measure the effect of the treatment in the form of practice using the trainer model. As this research involved only one class, the research design was one group pretest-posttest [10]. In one group pretest-posttest design model, a group will be subjected to pretest, then the treatment, and finally the posttest.…”

“…The analysis technique used was the gain normality test. This test was used to determine the effectiveness of the treatment given, with the followings reflects the gain normality test formula [10]:…”

“…Maximum score. The criteria for the effectiveness of the normality test values referred to the table from the meltzer in Octavia & Prasasty, 2019:598 which can be seen from the following Table 2[10].…”

Design of automatic turntable bottle cap sealing machine

“…With the advancement of science and technology, my country's manufacturing industry is developing rapidly. Many problems such as saving energy, saving manpower, saving costs, and improving efficiency are inevitable [1]. We need to improve and solve these problems, and adopt automation equipment to a greater extent to replace manual labor and some traditional mechanical equipment to meet the needs of our country's current social production.…”
