Abstract

Penelitian ini menangani masalah tingginya tingkat penolakan (1,93%) dalam manufaktur komponen elektronik HE-EC2 di sebuah perusahaan semikonduktor, yang melebihi tingkat target 0,60%. Dengan menerapkan metode DMAIC (Define, Measure, Analyze, Improve, Control), penelitian ini secara sistematis mengidentifikasi, menganalisis, dan memperbaiki akar penyebab masalah penolakan. Analisis menunjukkan bahwa Gripper dalam proses Final Assy adalah penyumbang utama penolakan. Untuk mengatasi hal ini, parameter gripper, awalnya diatur pada 14 mm, dikurangi secara metodis menjadi 10 mm. Penyesuaian ini menghasilkan penurunan substansial dalam tingkat penolakan, dari 1,93% menjadi 0,57%. Analisis statistik menunjukkan bahwa tingkat cacat awal setara dengan DPMO (Defects Per Million Opportunities) sebesar 2751 dan nilai sigma sebesar 4,28. Setelah penyesuaian parameter, tingkat penolakan menurun menjadi DPMO sebesar 815, disertai peningkatan nilai sigma menjadi 4,65. Keberhasilan penerapan metode DMAIC, terutama dengan fokus pada parameter Gripper dalam proses Final Assy, menandakan peningkatan signifikan dalam kualitas produk. Penelitian ini menekankan efektivitas pendekatan sistematis dalam mengidentifikasi dan mengatasi faktor-faktor kunci yang memengaruhi penolakan, akhirnya mendekati tingkat penolakan yang ditargetkan sebesar 0,5%. Wawasan yang diperoleh dapat menjadi acuan berharga bagi perusahaan manufaktur yang bertujuan meningkatkan kualitas produk melalui optimasi proses yang tepat.

Abstract

Kontribusi pertumbuhan industri manufaktur tidak terlepas dari adanya peranan pekerja dalam pengelolaannya. Untuk mendapatkaan hasil ukuran kerja manusia yang terbaik, maka dibutuhkan pengukuran waktu kerja. PT. ABC belum mengetahui secara pasti berapa waktu standar dan tingkat produktivitas pada proses packing, sehingga perlu melakukan pengukuran waktu kerja. Metode studi waktu dan gerak telah digunakan untuk mengukur waktu kerja, yaitu menilai waktu standar dan produktivitas pekerja diberbagi sektor industri. Untuk menentukan waktu standar, diawali dengan menghitung waktu siklus dan waktu normal serta mempertimbangkan tingkat penyesuaian dan kelonggaran. Berdasarkan hasil pengolahan data dan pembahasan diperoleh bahwa waktu standar sebelum perbaikan sebesar 42,56 detik, sedangkan setelah perbaikan melalui koreksi gerak dan waktu, jumlah waktu standarnya menurun menjadi 40,79 detik. Untuk menghitung produktivitas pekerja berdasarkan hasil perbandingan jumlah output produk yang dihasilkan dengan jumlah pekerja. Hasil perhitungan produktivitas pekerja pada proses packing setelah koreksi perbaikan sebesar 96,59%, hal ini menunjukkan bahwa produktivitas pekerja dapat dikategorikan baik dan terjadi peningkatan produktivitas pekerja sebesar 3,5%.

Abstract

In the era of Industry 4.0, digital transformation integrates advanced technologies such as the Internet of Things (IoT), artificial intelligence, and data-driven manufacturing, driving advancements in science and technology. Within this framework, this study focuses on the design and fabrication of a cantilever-type 3D printer aimed at producing a prototype capable of efficient and functional 3D object printing. Additive Manufacturing (AM) technology, particularly Fused Deposition Modeling (FDM), enables the conversion of digital designs into physical products through the layer-by-layer deposition of material. The 3D printer is designed using the VDI 2221 methodology, which encompasses four key phases: task clarification, conceptual design, embodiment design, and detailed design. A key consideration during the design process is the use of filaments derived from plastic bottle waste to mitigate environmental impact. The results identify the Cartesian model variant (Variant 1) as the optimal solution, selected based on functional performance, cost efficiency, and ease of assembly. This machine achieves nozzle temperatures up to 270°C and bed temperatures up to 80°C, with a total production cost of Rp 3,657,000.00. These findings demonstrate the potential of 3D printing technology to advance plastic waste recycling and promote the development of more sustainable 3D printing solutions.

Abstract

The quality control process implements continuous improvements using the Plan Do Check Action (PDCA) method. It uses seven tools where quality control is carried out from the initial production process, ongoing production, and up to finished production. Even though the quality control process has been carried out, the quality of the product is still poor, especially in the area of line spray painting. Data per July-September 2023 recorded 873 defective units with the most dominant spray dust defects with 543 defective units. Using the PDCA method aims to map all the problems above, the purpose of this study is to find out the causes of the most dominant reject spray dust and to find out the factors and determine solutions to reduce spray dust rejection. The PDCA method is used to make improvements that are known. several factors cause spray dust rejection due to the lack of routine maintenance procedures resulting in the performance of the spray gun not being maximized, not cleaning the gun spray every time the process changes which causes the rest of the spray to clog, paint that has expired causing the quality of the paint not to be optimal, lack of control over room temperature and the place for sterilization to enter the spray room is a factor for the large number of rejected spray dust. October-December 2023 recorded a decrease in reject spray dust units from 543 units to 243 units reject.
