Perancangan dan Pembuatan Modul Rangkaian PLC Sebagai Alat Pengontrol Sistem Berbasis CX Programmer Pada Mata Pelajaran Sistem Pengendali Elektronika di SMKN 2 Bojonegoro

Design and Making of PLC Circuit Modules as CX Programmer-Based System Contoroller in the Electronic Control Systems Subjects at SMKN 2 Bojonegoro

Penelitian dilatar belakangi hasil observasi di Jurusan TEI SMKN 2 Bojonegoro terdapat masalah pada fasilitas praktikum disebabkan harga trainer mahal, sedang didunia kerja alat industri terus berkembang. Penelitian bertujuan menghasilkan ”Modul Software CX Programmer V.9.7 untuk Pembuatan Rangkaian PLC” sebagai modul ajar pada Mata Pelajaran Sistem Pengendali Elektronika di Jurusan TEI yang layak berdasarkan aspek kevalidan, kepraktisan, dan keefektifan. Modul ini ditunjang dengan adanya CX Desainer  guna menekan biaya dan mengikuti perkembangan peralatan industri ketika praktikum. Penelitian ini memakai jenis penelitian kuantitatif dengan metode eksperimen yang  menghasilkan kelayakan modul pada aspek kevalidan sebesar 97%, dikategorikan sangat valid. Menghasilkan kelayakan modul pada aspek kepraktisan sebesar 90%, dikategorikan sangat praktis. Menghasilkan kelayakan modul pada aspek keefektifan ranah kognitif ( pretest & posttest ) dimana uji statistik paired sample t - test mendapat Asymps. Sig. (2 - tailed) sebesar 0,000 < 0,05 maka, terdapat perbedaan signifikan hasil belajar pretest & posttest. Lalu pada ranah psikomotorik (hasil praktikum) dimana uji statistik one sample test mendapat Asymps. Sig. (2 -tailed) sebesar 0,000 < 0,05 dengan hasil nilai mean  88,75 lebih besar dari 75. Dari hasil pengujian dua ranah tersebut ialah Ho ditolak dan Hı diterima, dikategotikan efektif. Sehingga disimpulkan modul ajar layak digunakan untuk pembelajaran. 

The research is based on the results of observations in the TEI Department of SMKN 2 Bojonegoro there are problems in practicum facilities due to the expensive price of trainers, while in the world of industrial equipment work continues to develop. The research aims to produce "CX-Programmer Software Module V.9.7 for the Creation of PLC Circuits" as a teaching module in the Electronic Control System Subject in the TEI Department that is feasible based on the aspects of validity, practicality, and effectiveness. This module is supported by the existence of CX-Designer to reduce costs and keep up with the development of industrial equipment during practicum. This study uses a type of quantitative research with an experimental method that produces the feasibility of the module in the aspect of validity of 97%, categorized as very valid. Producing module feasibility in the practicality aspect of 90%, categorized as very practical. Producing module feasibility in the aspect of cognitive domain effectiveness (pretest & posttest) where the paired sample t-test statistical test gets Asymps.Sig.( 2-tailed) of 0.000<0.05, therefore, there was a significant difference in pretest  & posttest learning outcomes. Then in the psychomotor realm (practicum results) where the statistical test one sample test got Asymps.Sig.( 2-tailed) of 0.000<0.05 with a mean value of   88.75 greater than 75. From the results of the testing of the two domains, Ho was rejected and Hı was accepted, categorized as effective. So it was concluded that the teaching module was suitable for learning.
