Abstract

The frame of the nyamplung bean peeling machine is a very important component in this design, the frame functions as a fulcrum for the mechanical and electrical components. The problem that occurred during observations was that when testing the nyamplung bean peeling machine at maximum rotation, the frame experienced vibrations. The aim of this research is to determine the stress distribution and deflection resulting from static loading on the frame of the Nyamplung bean peeling machine and to compare hollow tube materials with angle iron, which of these two types of material is more efficient. The framework structure was designed and analyzed using Solidwork 2021 software. There are several tests used, but most often the computational method is used using the Finite Element Method (FEM). In frame 1 calculations using housing and crusher loading of 50kg. The results of the simulation obtained a bending strength of 18 N/mm2, while manual calculations obtained a result of 19.94 N/mm2. Permissible stress in ASTM A36 material 160 N/mm2. The displacement in manual calculations was found to be 0.120 mm, whereas using simulation it was 0.077 mm. In frame 2 the results obtained from manual calculations were with a bending stress of 13.84 N/mm2. And with simulation the results obtained were 13 N/mm2, and the displacement in manual calculations was obtained at 0.117 mm, whereas using simulation it was 0.08 mm

Abstract

Improving machine productivity and effectiveness is a crucial factor in maintaining the competitiveness of manufacturing companies. One approach to improving equipment performance is Total Productive Maintenance (TPM), with Overall Equipment Effectiveness (OEE) as the primary indicator. This study aims to analyze the effectiveness of the Flow Mixer machine at PT ASI's Mold Shop Department based on its OEE value, which comprises availability, performance, and quality. It also identifies the dominant factors causing low machine effectiveness using the Six Big Losses approach and a fishbone diagram. The research data were obtained from production data, planned and unplanned downtime, the number of defective products, and machine operating time during September–November 2025. The calculation results show that the Flow Mixer machine's OEE values ​​were 66% (September), 68% (October), and 68% (November), respectively, which are still below the world-class OEE standard of 85%. The main factors influencing the low OEE are breakdowns and process defect loss. Improvement proposals are based on the eight pillars of TPM, which focus on improving machine maintenance, operator skills, and standardizing work procedures. Implementation of the proposed improvements in December resulted in an increase in the OEE value to 72%. The results of this study demonstrate that consistent TPM implementation can improve the effectiveness of the Flow Mixer machine and the productivity of the production process.

Abstract

Proses pelubangan pada cover amrest plastik di PT. XYZ saat ini masih dilakukan secara manual menggunakan gerinda tangan sehingga berpotensi menimbulkan ketidakkonsistenan kualitas serta rendahnya produktivitas. Penelitian ini bertujuan merancang dan membuat dies plecing untuk meningkatkan presisi dan efisiensi proses pelubangan. Material cover armrest menggunakan plastik ABS dengan ketebalan 3 mm dan nilai shear strength sebesar 67 MPa. Perancangan dies dilakukan menggunakan perangkat lunak Autodesk Fusion 360, kemudian diproduksi menggunakan mesin CNC milling dan diuji mesin press berkapasitas 15 Ton. Hasil perhitungan menunjukkan kebutuhan gaya pelubangan sebesar 8,46 tonf untuk dua lubang. Pengujian menunjukkan bahwa dies piercing mampu menghasilkan lubang sesuai spesifikasi dimensi dan meningkatkan kapasitas produksi secara signifikan dari 90 set per shift pada proses manual menjadi 1.920 set per shift. Hasil penelitian menunjukkan bahwa penerapan dies piercing efektif meningkatkan presisi proses serta efisiensi produksi pada komponen cover armnest plastik.

Abstract

Kerusakan roller bearing pada komponen rotor mesin kompresor udara tipe screw mengakibatkan terjadinya vibrasi, mengeluarkan suara noise dan terdapat gram-gram besi. Tujuan dalam penulisan ini yaitu melakukan analisis untuk mengetahui penyebab kerusakan bearing dengan cara pengukuran shock pulse dBm/dBc. Dalam melakukan analisis ini metode yang digunakan yaitu pengukuran shock pulse dengan mengukur denyut kejut pada bearing akibat gaya impact yang terjadi, intensitas denyut kejut itulah yang mengindikasikan besarnya kerusakan pada bearing. Dari hasil analisis terindikasi ada bearing yang mengalami kerusakan dengan pengukuran shock pulse pada titik keempat atau bearing screw D mendapatkan nilai 24 dBm dan bearing screw E mendapat nilai 22 dBm, hasil pembongkaran pada bearing screw D mengalami fracture and cracking dan Pada bearing screw E mengalami abrasive wear. Indikasi kerusakan ini bisa terjadi dari beberapa faktor, seperti faktor pemasangan bearing yang salah dan terjadi misalignment atau faktor lubrikasi bearing yang salah. Maintenance yang dilakukan yaitu penggantian bearing yang rusak dengan yang baru, dan perlu diperhatikan saat pemasangan bearing lebih berhati-hati untuk menghindari indikasi penyebab terjadinya masalah yang terulang kembali
