Abstract

Motor pompa MP 1101 ini sebagai motor air umpan boiler yang mengalirkan air yang telah selesai melalui proses demineralisasi menuju ke boiler di bagian pemeliharaan III PT. Petrokimia Gresik. Motor pompa ini dilengkapi dengan proteksi EOCR (Electronic Over Current Relay), yaitu sebuah peralatan yang berfungsi untuk mengamankan motor ketika terjadi gangguan arus lebih. Alat pengaman ini dapat bekerja untuk memutus aliran listrik menuju ke motor pompaMP 1101 apabila motor terjadi gangguan over current ataupun gangguan yang termasuk di dalam karakteristik EOCR.dari analisis yang dilakukan dapat ditarik beberapa kesimpulan bahwa karakteristik yang dimiliki sistem proteksi EOCR lebih banyak dari pada Over Current, proteksi EOCR sebanyak 9 dan 3 yang terdapat pada Over Current. Gangguan yang sering terjadi pada motor lebih banyak disebabkan kondisi panas pada bearing dan membutuhkan over houl setiap 1 tahun sekali. Dalam perhitungan arus starting motor diperoleh 185,3 A atau 6 kali arus nominal motor, sedangkan dalam pengaturan yang terseting oleh teknisi 8 kali arus nominal. Pengaturan untuk arus starting ini tidak boleh terlampau dari set poin yang ditentukan, hal ini dapat mengakibatkan motor terbakar. Gangguan selain dari sistem kelistrikan yaitu panas yang sering terjadi pada bearing motor, hal ini dapat diminimalisir dengan pemberian greasing/pelumas secara terjadwal agar kinerja motor dapat berjalan dengan baik dan tidak mendapatkan suhu yang berlebihan. Kata Kunci: EOCR, Motor Pompa MP 1101, Over Current, Proteksi.

Abstract

Sistem distribusi kelistrikan merupakan salah satu faktor yang dibutuhkan dalam mentransmisikan sumber daya menuju beban agar dapat digunakan sesuai kebutuhan. Kualitas tenaga listrik yang baik akan menghasilkan produksi daya yang diberikan ke beban bisa maksimal. Analisa sistem saluran dilakukan untuk mngetahui besar dan sudut fasa tegangan pada setiap saluran (bus), daya nyata dan daya reaktif yang ada pada setiap saluran. Hasil analisis aliran daya dapat digunkan untuk menentukan jumlah kerugian (daya dan rugi tegangan), sehingga dapat dilakukan optimasi dengan penambahan komponen kelistrikan untuk mengtasi adanya rugi tegangan pada sistem saluran. Dengan menjaga sistem aliran daya yang ada maka daya yang diberikan ke beban akan maksimal. Hal ini akan mengoptimalkan proses produksi yang ada di industri.

Abstract

This service aims to improve the technical skills of Dawarblan-dong National Vocational School students through project-based learning with an automation approach to agricultural equipment. The service method used is class action service. The service instruments used are observation, tests and interviews. The service subjects were 30 students of class XI Automotive Light Vehicle Engineering. Data were analyzed using descriptive statistics. The results of the service show that project-based learning with an automation approach to agricultural equipment can significantly improve the technical skills of Dawarblandong National Vocational School students. This is proven by the increase in student test scores from an average of 65.00 to 80.00 after taking part in the learning. Apart from that, the results of observations show that students become more active and creative in learning. Students are also more motivated to learn and complete projects. The results of the interviews showed that students felt happy and challenged by project-based learning with an automation approach to agricultural equipment. Project-based learning with an automation approach to agricultural tools can be an effective learning alternative for improving the technical skills of Dawarblan-dong National Vocational School students. This learning can improve students' knowledge, skills and attitudes in the field of engineering.

Abstract

Mastery of mechatronics skills is a key factor in enhancing the competitiveness of vocational high school (SMK) graduates, especially in the era of Industry 4.0. This study aims to develop the mechatronics skills of SMK Puger students through a Remotely Operated Vehicle (ROV) project. The method used in this research is a project-based learning approach, involving the design, assembly, and testing of the ROV directly by students. The results show that the implementation of this project improves students' understanding of electrical systems, microcontroller programming, and mechanical assembly skills. Furthermore, this project also enhances teamwork and problem-solving skills. Thus, the development of mechatronics skills through the ROV project can be an effective alternative in improving the quality of learning in vocational schools. This research makes several significant contributions to vocational education, particularly in enhancing students’ mechatronics competencies through a practical and innovative learning model. These findings suggest that integrating PjBL and technological innovation in vocational education is a viable and impactful method to enhance student learning outcomes and workforce readiness
