PENGEMBANGAN JOBSHEET PROGRAMABLE LOGIC
CONTROLLER (PLC) BERBASIS LOGO SOFTCOMFORT
UNTUK KELAS XII TITL SMK 1 PUNGGING
DEVELOPMENT OF JOB SHEET PROGRAMMABLE LOGIC
CONTROLLER (PLC) BASED ON LOGO SOFTCOMFORT
FOR GRADE XII AT SMKN 1 PUNGGING
Penelitian ini bertujuan untuk mengetahui tingkat
kelayakan yang ditinjau dari aspek kevalidan, tingkat kepraktisan,
serta tingkat keefektifan dari Job Sheet PLC berbasis Logo
Softcomfort
Pengembangan menggunakan metode penelitian Research
and Development (R&D). Penelitian ini menggunakan desain uji
coba one-group pretest-posttest design dan dilakukan pada peserta
didik kelas XII TITL 1 sebanyak 34 peserta didik. Penelitian ini
menggunakan instrumen validasi job sheet, dengan kepraktisan
pada repon peserta didik,dan keefektifan dari nilai kognitif pretest dan posttest peserta didik.
Hasil penelitian menunjukkan kevalidan jobsheet
menghasilkan rating 94,19 dengan kategori “sangat valid”.
Kepraktisan jobsheet PLC, menghasilkan rating 91,35 dengan
kategori “sangat praktis”. Untuk tingkat keefektifan jobsheet PLC
dengan hasil belajar kognitif menghasilkan nilai thitung = 18,738,
dengan nilai ttabel (df = 66, = 0,05) = 1,997, memperoleh nilai sig.
sebesar 0,000. Berdasarkan hasil penelitian tersebut, Jobsheet PLC
berbasis softcomfort ini dapat dikatakan layak secara valid, praktis,
serta efektif digunakan dalam pembelajaran IML di SMK Negeri 1
Pungging..

This study aims to determine the level of feasibility assessed
from the aspects of validity, practicality, and effectiveness of the
PLC-based Logo Softcomfort Job Sheet. Development utilized the
Research and Development (R&D) research method. This study
employed a one-group pretest-posttest design and was conducted
on 34 students of XII TITL 1 class. The research employed a
validation instrument for the job sheet, with practicality assessed
through student responses, and the effectiveness measured
through the cognitive pre-test and posttest scores of students.
The results indicate that the job sheet's validity yielded a
rating of 94.19, categorized as "very valid." The practicality of the
PLC job sheet resulted in a rating of 91.35, categorized as "very
practical." Regarding the effectiveness of the PLC job sheet on
cognitive learning outcomes, it resulted in a calculated t-value of
18.738, with a critical t-value (df = 66, α = 0.05) of 1.997, obtaining
a significance value of 0.000. Based on these findings, the PLC job
sheet based on Softcomfort can be considered valid, practical, and
effective for use in IML learning at SMK Negeri 1 Pungging.
