Abstract

The redesign of the die design in the blank-pierce process for the RH/LH quarter panel extension reinforcement product was carried out using field observations to obtain actual data. The production process consists of five stages: blanking, piercing, restriking, bending and forming. Meanwhile, in the redesign process, the RH/LH quarter panel extension reinforcement product is evaluated in the blanking and piercing die processes. Cycle time analysis after the tool design has been redesigned shows the potential for increasing efficiency by reducing process time. MPP data is used as a guide for die design with relevant machine specifications, die size and materials. Machine pressure and tonnage calculations were carried out for the current die design and the revised version, showing significant improvements in production efficiency. The die redesign was carried out to increase output per stroke and to use more sophisticated automation processes. The results of this research show that improved die design can increase production efficiency and productivity by reducing the number of strokes required and properly adjusting machine capacity.

Abstract

Sistem inventaris barang khususnya alat dan bahan di bidang praktikum memiliki peran penting dalam mendukung efisiensi dan efektivitas proses pembelajaran di Program Studi Teknologi Rekayasa Otomotif Politeknik STMI Jakarta. Alat dan bahan yang digunakan untuk pembuatan dies merupakan bagian dari praktikum mata kuliah dies mupun jig yang perlu dilakukan inventory yaitu meliputi bahan baku logam seperti baja atau aluminium, mesin bubut, mesin cnc, dan beberapa peralatan pengukur presisi seperti mikrometer. Penelitian ini bertujuan untuk merancang dan membangun Sistem Inventory Barang Praktikum Otomotif menggunakan metode prototyping. Metode prototyping dipilih karena memungkinkan pengembangan sistem secara iteratif dan responsif terhadap kebutuhan pengguna. Sistem ini dirancang untuk memungkinkan pengguna (dosen dan mahasiswa) untuk mencatat, memantau, dan mengelola barang-barang praktikum otomotif dengan efisien. Proses penelitian melibatkan analisis kebutuhan, desain sistem, implementasi, dan evaluasi. Hasilnya adalah sebuah sistem yang dapat memfasilitasi manajemen inventaris praktikum otomotif dengan lebih efektif, meningkatkan ketersediaan barang, serta memperbaiki efisiensi penggunaan sumber daya di Program Studi Teknologi Rekayasa Otomotif Politeknik STMI Jakarta.

Abstract

Revolusi industri 4.0 mendorong integrasi teknologi cyber dalam ranah industri, termasuk penggunaan Big Data, Cloud Computing, manufaktur aditif, Internet of Things (IoT), dan kecerdasan buatan. Perusahaan-perusahaan, termasuk PT Fuji Seat Indonesia, mulai menerapkan teknologi untuk memperbarui sistem absensi karyawan dari yang awalnya manual menjadi berbasis digital, menggunakan teknologi fingerprint, sensor mata, atau pengenalan wajah. Dalam konteks ini, integrasi data absensi dengan teknologi fingerprint melalui Server Intranet Internal Perusahaan di PT Fuji Seat Indonesia memberikan manfaat dalam keamanan, efisiensi manajemen, dan peningkatan produktivitas. Sebelum integrasi, proses bisnis terfragmentasi dan bergantung pada pelaporan manual, sementara setelah integrasi, terjadi transformasi signifikan dalam pengelolaan akses, pengurangan biaya dan waktu, serta peningkatan akurasi data. Dengan demikian, integrasi ini membawa dampak positif terhadap efisiensi dan produktivitas perusahaan

Abstract

Plastic injection molding is a method of forming a product that uses plastic (Polymer) as the main material. The resulting product must have as few defects as possible because it will reduce the quality value and customer satisfaction. In this study, the mold was made for the Front towing bumper cover product with the design and simulation stages. The simulation process uses Moldflow Software to identify possible product defects that occur with variations in melt temperature of 200, 240, and 280 (°C). The result obtained in this simulation is the optimal melt temperature for producing products in the injection molding process by selecting a temperature of 240°C. This temperature is the most optimal because it has faster fill time and cooling time, with an optimum percentage of 25% compared to the temperatures of 200 and 280 (°C). In potential defects such as air traps, weldlines, and shinkmarks, a temperature of 240 (°C) has fewer potential defects than 200 and 280 (°C).

Abstract

Modern manufacturing industries demand high efficiency and consistent product quality, especially in metal forming processes such as stamping dies. An accurate punch and die design essential to ensure the success of bending operations, particularly for metal-based products like forks. This study aims to evaluate the structural reliability of punch and die designs through a static simulation approach as a quality confirmation method prior to manufacturing. The methodology includes die geometry design, selection of SKD11 tool steel based on its mechanical properties, and stress analysis using SolidWorks software under a static load of 35 tons. The stress distribution was analyzed using the Von Mises method, and the Factor of Safety (FOS) was calculated as a design safety indicator. Simulation results show that the maximum stress on the die was 9.91 × 10⁷ N/m² and on the punch was 1.01 × 10⁸ N/m², both well below the yield strength of SKD11 (6.88 × 10⁸ N/m²). The FOS values of 3.47 for the die and 3.26 for the punch confirm structural safety. Validation through trial dies and 3D scanner measurements indicated dimensional deviations within the acceptable tolerance range. This approach effective for improving design accuracy and production efficiency in stamping die manufacturing.
