Abstract

The rapid advancement of Industry 4.0 has catalyzed the integration of artificial intelligence (AI) into smart manufacturing, with predictive maintenance emerging as a crucial application to reduce downtime and optimize operational efficiency. This study aims to develop and evaluate a deep learning-based predictive maintenance model by leveraging real-time sensor data from a smart factory environment. A convolutional neural network (CNN) architecture was implemented to detect anomalies and predict machinery failures in advance. The dataset, consisting of multivariate time-series signals from industrial sensors, was preprocessed and used to train, validate, and test the model’s predictive performance. Results indicate that the proposed deep learning model achieved a prediction accuracy of 94.6%, outperforming traditional statistical and machine learning methods in both precision and recall. The implementation of this AI-driven system enables proactive maintenance strategies, minimizing production losses and extending equipment lifespan. In conclusion, the research demonstrates the feasibility and effectiveness of deep learning in predictive maintenance applications for smart manufacturing systems and offers a scalable solution adaptable to diverse industrial settings.

Abstract

Abstract: Primary packaging is packaging that comes into direct contact with the product. This packaging serves to protect, preserve, and package the product, as well as provide important information to customers. As the main container, this packaging comes into direct contact with the product and maintains its quality until it reaches the customer. PT XYZ is a leading primary packaging manufacturer. The company produces three different variants of its flagship product, steel drums, which generate the most revenue. The oil, lubricant, food, and chemical sectors use steel drums. A large number of defects in finished products are caused by drum body rejection and top-bottom drum rejection. From the report data of 1,166 units produced in 2024, the most rejections came from the top-bottom production process, which consists of eight phases: pressing, opening, closing, puncture 1, puncture 2, fully open drum head puncture, head coating, and other processes. The results of this study show that UCL=0.00451 and LCL=0.00247. The sigma level is determined by converting the process after the process DPMO value is known. With a value of 436, the company's sigma level is 4.83 when the DPMO value is entered into the sigma-DPMO relationship table. Keyword: quality control; six sigma; DMAIC; reject Abstrak: Kemasan primer merupakan kemasan yang bersentuhan langsung dengan produk, kemasan ini berfungsi untuk melindungi, menjaga, dan mengemas produk, serta menyediakan informasi penting bagi pelanggan. Sebagai wadah utama, kemasan ini bersentuhan langsung dengan produk dan menjaga kualitasnya hingga sampai ke pelanggan. PT XYZ, perusahaan yang bergerak di bidang produsen kemasan primer terkemuka, perusahaan tersebut memproduksi tiga varian berbeda dari produknya produk andalannya, drum baja, menghasilkan pendapatan terbesar. Sektor minyak, pelumas, makanan, dan kimia menggunakan drum baja. Jumlah cacat yang besar pada produk jadi disebabkan oleh penolakan badan drum dan penolakan atas-bawah drum. Dari data laporan sebanyak 1.166 unit yang diproduksi pada tahun 2024, penolakan terbanyak berasal dari proses produksi atas-bawah yang terdiri dari delapan fase yaitu penekanan, pembukaan, penutupan, tusukan 1, tusukan 2, tusukan kepala drum terbuka sepenuhnya, pelapisan kepala, dan proses lainnya. Hasil penelitian ini menunjukkan bahwa UCL=0,00451 dan LCL=0,00247. Tingkat sigma ditentukan dengan mengonversi proses setelah nilai DPMO proses diketahui. Dengan nilai 436, tingkat sigma perusahaan sebesar 4,83 ketika nilai DPMO dimasukkan ke dalam tabel hubungan sigma-DPMO. Kata kunci: pengendalian kualitas; Six Sigma; DMAIC; penolakan

Abstract

SMEs in Indonesia face significant challenges in optimizing their production due to limited resources, particularly in terms of time and labor. This study proposes the application of the Modified Wolfe Simplex Method to optimize the production of two main fashion products—shirts and trousers—within a clothing SME. The method employs principles of linear programming, Lagrangian functions, and Karush-Kuhn-Tucker (KKT) optimality conditions to identify efficient and strategic solutions. The main objective of this research is to determine the optimal production combination to maximize profit under time constraints in cutting and sewing processes. Production data were analyzed using an iterative Simplex approach, enhanced by Wolfe’s modification to explore system sensitivity to changes in resource availability. The results show that the optimal production consists of 8 shirts and 12 trousers, yielding a maximum profit of IDR 1,440,000. The Lagrange multipliers λ₁ = 8/19 and λ₂ = 18/19 indicate the potential for additional profit if work capacity is increased by one unit in each process. The shadow prices of the constraints further suggest opportunities for increased profitability through capacity expansion. This study concludes that the method is effective in supporting data-driven production decision-making. Future research is recommended to accommodate more variables and integrate digital systems for continuous optimization.
