Abstract

Guna mendukung proses pembelajaran sistem otomasi di sebuah lembaga pendidikan dibutuhkan sebuah alat peraga yang mudah dipelajari dan dimengerti oleh mahasiswa. Tujuan pembuatan alat peraga ini agar peserta didik mengetahui dan dapat mengimplementasikan proses kerja sistem otomasi di industri menggunakan media yang disimulasikan dalam bentuk alat peraga. Alat peraga yang digunakan adalah integrasi PLC-HMI pada aplikasi pengisian tangki air. Alat peraga dirangkai dengan menggunakan PLC dan HMI merk Omron dengan software CX-Programmer dan NB-Designer. Rangkaian wiring alat peraga PLC-HMI disusun secara teratur dan sistematis agar mudah dibongkar pasang dan disesuaikan dengan diagram wiring oleh peserta didik. Program ladder pada software CX-Programmer didesain dengan menerapkan logika dasar, instruksi dan beberapa fungsi program yang sesuai dengan level kompetensi dasar pembelajaran PLC. Desain tampilan dan fungsi HMI dirancang menggunakan software NB-Designer yang diintegrasikan dengan program ladder, serta disesuaikan penggunaan alamat I/O nya. Wiring alat peraga berfungsi secara normal sehingga seluruh perangkat dapat terkoneksi dengan baik. Program ladder yang telah dirancang dapat berfungsi optimal dan tidak didapati error pada hasil kompilasi. Desain HMI dapat berfungsi secara efektif untuk monitoring proses maupun saat berfungsi sebagai programmable terminal. Secara keseluruhan hasil rancang bangun alat peraga simulasi sistem pengisian tangki air telah diuji coba dan berfungsi sesuai rancangan yang telah ditetapkan.

Abstract

The increasing demand for skilled human resources in the field of automation by the workforce has encouraged vocational education institutions to align their graduates' competencies with industry needs. Students must be equipped with up-to-date skills in line with technological advancements. Currently, the availability of technical expertise programs in vocational high schools (SMK) that include industrial automation curricula is very limited. This situation does not align with the growing industrial demand for SMK graduates with automation competencies, such as wiring and PLC programming skills. Based on these circumstances, this automation system training based on PLC was conducted as part of a community service program. The activity aimed to enhance the skillsets of vocational high school students, particularly in the machining engineering department. The training utilized PLC-based automation systems with Omron CP1E E30-DR-A controllers. The PLC logic programming was performed using CX-Programmer software. The results of the program showed that most participants could grasp the material well. Moreover, all participants gained new insights and skills in industrial automation systems, which serve as valuable support when entering the workforce.

Abstract

This study investigates the effect of sodium silicate (Na₂SiO₃) and boric acid (BA) as flame-retardant additives in unsaturated polyester resin (UPR) reinforced with E-glass fibres. The fire performance of the composites was evaluated based on varying additive concentrations by % volume fraction, using standardised testing methods in burning rate (BR) with ASTM D 635-22. Results indicate that Na₂SiO₃ contributes to fire resistance by forming a thermally stable, glass-like barrier, while BA proves more effective by interrupting combustion reactions and generating protective boron oxide residue. Notably, the combination of Na₂SiO₃ and BA produced a synergistic effect, resulting in a significant reduction in burning rate. Thermogravimetric analysis (TGA) further confirmed the enhanced thermal stability of the composite, particularly in the NB10 formulation with 2% Na₂SiO₃ and 8% BA, which demonstrated the slowest degradation at elevated temperatures. These findings suggest that optimising the ratio of Na₂SiO₃ and BA yields high-performance, fire-retardant composites suitable for applications demanding superior fire resistance and thermal durability, such as electric vehicle safety components.

Abstract

This study aims to implement and test the effectiveness of the jigsaw learning model based on project based learning in improving students' skills and learning outcomes in the subject of lathe machining at SMK Negeri 5 Sukoharjo. The method used is a quasi-experimental design with a two-group pre-test post-test design, involving 68 students divided into an experimental group and a control group. Data collection was carried out through pre-test and post-test, observation, and documentation. The results of the analysis showed a significant increase in the experimental group's learning outcome score with an average post-test score of 79.85 or an increase of 34.07% compared to the average pre-test score of 59.56. In contrast, the control group only experienced an increase of 28.3%, from an average of 55.44 to 71.18. The t-test showed a significant difference between the experimental group and the control group (p <0.05). N-Gain analysis also showed high effectiveness in the experimental group (0.5166) compared to the moderate category in the control group (0.3503). In addition, the observation results showed an increase in motivation, active participation, and student cooperation during the learning process. Thus, the combination of the jigsaw model with project-based learning has proven effective in improving student learning outcomes and skills significantly compared to conventional learning methods. This study contributes to the development of contextual and collaborative vocational learning strategies to face the demands of the industrial world.
