Abstract

The manufacturing industry is continuously challenged to improve production efficiency and quality. Production machinery plays a crucial role in supporting smooth manufacturing processes, especially in the fabrication of special vehicle components. One such machine is the TruLaser 1030, a 2D laser cutting machine manufactured by TRUMPF, which is used for processing body and accessory parts in special vehicles. This study aims to evaluate the performance of the TruLaser 1030 machine using the Overall Equipment Effectiveness (OEE) method, as well as to identify damaged machine components and maintenance requirements. The Total Productive Maintenance (TPM) approach is applied to enhance equipment effectiveness, prevent breakdowns, and ensure product quality and workplace safety. The OEE methodology involves three main parameters: Availability, Performance Rate, and Quality Rate. The results show the machine’s availability at 94%, performance rate at %, and quality rate at 97.1%. These findings suggest that the TruLaser 1030 machine operates at a relatively optimal level; however, regular evaluations of work systems and maintenance programs are necessary to maintain stable performance and continuously improve productivity.

Abstract

Geometri merupakan materi penting dalam pengembangan kemampuan berpikir logis, kritis, dan sistematis siswa sekolah dasar, namun sering menjadi tantangan bagi siswa kelas rendah karena sifat konsep yang abstrak. Penelitian ini bertujuan untuk mengkaji strategi pembelajaran geometri yang efektif, termasuk penggunaan media konkret, model pembelajaran inovatif, pendekatan kontekstual, etnomatematika, dan strategi adaptif. Metode penelitian menggunakan studi literatur dengan menganalisis jurnal-jurnal nasional terkait pembelajaran geometri pada siswa sekolah dasar. Hasil kajian menunjukkan bahwa media konkret membantu siswa memahami konsep abstrak secara nyata, sementara model problem solving, PBL, dan kooperatif dengan penemuan terbimbing meningkatkan kemampuan berpikir kritis dan pemecahan masalah. Pendekatan kontekstual dan etnomatematika memperkaya pengalaman belajar dan membuat konsep lebih bermakna. Strategi adaptif memastikan pembelajaran sesuai dengan karakteristik siswa. Penerapan strategi pembelajaran yang komprehensif ini efektif dalam meningkatkan pemahaman konsep geometri serta keterampilan berpikir siswa.
