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

Bus is a very important transportation for all people in the world. The majority of a bus that operates still uses non-renewable fuel. The conventional bus produces exhaust emissions that can damage the environment. Current research is about changing the conventional internal combustion engine bus into an electric bus, therefore it is necessary to test the strength of the frame structure to determine its strength after changing with the electric system. The objective of this current study is to analyze the bending strength and optimization of a medium electric bus frame structure using the Finite Element Method in static conditions. Optimization will be conducted after obtaining results of bending analysis to determine the minimum weight of the bus frame structure without violating bending strength. The results of the bending analysis are stress and displacement which will be used as a constraint in the optimization process. The optimization that will be used is size optimization. The design variable is the thickness of each bus frame structure. Results show that the weight of the structure is reduced by 12% without compromising on strength and safety requirements.

Abstract

This study aims to determine the effect of the addition of montmorillonite bentonite powder on the mechanical properties and burn resistance of phenolic resin-based composites. Composite samples were made with variations in bentonite weight fractions of 0%, 5%, 10%, and 15%. The impact test was carried out using the Izod method to determine the energy absorption and impact price, while the burn resistance was tested based on the ASTM D635 standard to determine the Time of Burning (TOB) and the Rate of Burning (ROB). The test results showed that the addition of bentonite lowered the impact price, with the highest value of 0.0082 J/mm² in the 0% fraction and the lowest of 0.0008 J/mm² in the 5% fraction. The highest absorption energy is obtained in the 10% fraction of 0.145 J. This decrease in mechanical performance is influenced by the inhomogeneous distribution of the catalyst and the presence of voids in the composite structure. In contrast, the addition of bentonite provides a significant increase in burn resistance. Composites with a fraction of 15% show the highest TOB of 20 seconds and the lowest ROB of 9.4 mm/min, indicating increased flame resistance. The mineral content of montmorillonite in bentonites, such as silica and alumina, contributes to slowing down the rate of combustion through increased material density and stable thermal properties. The results of this study show that montmorillonite bentonite powder has the potential to be used as a flame retardant additive in composite materials, but it needs to be studied further to maintain a balance between fire resistance and mechanical strength.

Abstrak: UMKM Sejahtera Abadi di Kabupaten Wonosobo menghadapi masalah rendahnya umur simpan keripik carica, hanya 1–2 bulan, akibat kadar air tinggi dari proses pengeringan konvensional. Kegiatan pengabdian ini bertujuan meningkatkan hardskill mitra untuk memperpanjang umur simpan dan efisiensi produksi melalui penerapan teknologi food dehydrator. Metode yang digunakan meliputi sosialisasi, pelatihan, dan pendampingan kepada delapan tenaga kerja mitra, disertai evaluasi melalui wawancara dan observasi. Hasil menunjukkan peningkatan keterampilan teknis mitra rata-rata sebesar 52% dalam pengoperasian alat, pengontrolan kadar air, dan manajemen produksi. Penerapan food dehydrator berhasil menurunkan kadar air dari 6–8% menjadi 4,2% yang dapat memperpanjang umur simpan menjadi 5–6 bulan. Teknologi ini tidak hanya meningkatkan kualitas dan keawetan produk, tetapi juga mendorong peningkatan nilai ekonomi dan keberlanjutan usaha UMKM.Abstract: The Sejahtera Abadi MSME in Wonosobo Regency faces the problem of a short shelf life of carica chips, only 1–2 months, due to the high water content from the conventional drying process. This community service activity aims to improve partners' hard skills to extend shelf life and production efficiency through the application of food dehydrator technology. The methods used include socialization, training, and mentoring for eight partner workers, accompanied by evaluation through interviews and observations. The results show an average increase in partners' technical skills of 52% in equipment operation, water content control, and production management. The application of the food dehydrator successfully reduced the water content from 6–8% to 4.2%, which can extend the shelf life to 5–6 months. This technology not only improves product quality and durability, but also encourages increased economic value and sustainability of MSME businesses.
