Abstract—This study discusses the validity test analysis of a
Virtual Laboratory-Based Job Sheet (VLBJS), which is used as
a practicum learning medium for vocational education students
in higher education. The Virtual laboratory-based Job Sheet is
used as a practicum guide for students in the Power Electronics
Practicum Course, at the Department of Electrical Engineering,
Universitas Negeri Padang, Indonesia. Validity test analysis is
important to ensure that this VLBJS is suitable for use in the
learning process. This study involved 18 experts: learning
material experts, learning media experts, and language experts.
The rubric for assessing validity with a Likert scale was used to
collect the research data. The validity test analysis was carried
out based on the results of the expert's assessment by filling out
the validity assessment instrument. Partial Least Square (PLS)
analysis was used to analyze the validity and reliability of the
indicators of each variable in the research instrument.
Meanwhile, the analysis of validity tests on Virtual
Laboratory-Based Job Sheets was carried out using the Aikens'
V formula. The results showed that Virtual Laboratory-Based
Job Sheets met the valid criteria from all aspects, namely the
aspects of learning materials, learning media, and language.
Thus, it can be concluded that the Virtual Laboratory-Based
Job Sheet is valid as a practicum guide for vocational education
students in the Power Electronics Practicum learning process.
Index Terms—Virtual Laboratory, job sheets, vocational
education students, validity test analysis
