Abstract

This study aims to improve the Availability value in calculating the Overall Equipment Effectiveness (OEE) of a 3-Axis Vertical Milling machine at PT. XYZ. Low Availability value is an indicator of frequent unplanned downtime, which significantly hinders productivity. The proposed approach is the integration of the Failure Mode and Effect Analysis (FMEA) method with the implementation of a structured Preventive Maintenance (PM) program. FMEA is used to identify and prioritize potential failure modes in machine components based on the Risk Priority Number (RPN) value, which is obtained from the multiplication of Severity, Occurrence, and Detection. The FMEA results indicate that critical failure modes are dominated by problems in the spindle system, cooling system, and axis movement servo system, with the highest RPN values. Based on these critical findings, a customized PM program was developed, including scheduled inspections, relubrication, and component replacement before failure occurs. After the implementation of the PM program during the observation period, the average Availability value of the 3-Axis Vertical Milling machine increased from 63% to 74%. This increase in availability contributed to an increase in the total OEE value. This study demonstrated the effectiveness of combining FMEA and preventive maintenance as a robust strategy for minimizing unplanned machine downtime, thereby optimizing equipment performance and increasing operational competitiveness.

Abstract

This study aims to analyze the causes of the low availability value of the Siebler 1 machine at PT Kimia Farma using the Overall Equipment Effectiveness (OEE) approach. The research method employed is descriptive quantitative, utilizing machine operational data from January to October 2025. The three main components of OEE—availability, performance, and quality were calculated and analyzed to identify the factors that most significantly affect machine effectiveness. The results indicate that the average OEE value of the Siebler 1 machine is 37.68%, which is far below the industrial effectiveness standard of 85%. Availability is identified as the main contributor to the low OEE, with an average value of only 53.40%, caused by high downtime resulting from mechanical failures in the feeder and heating unit, as well as inconsistent implementation of preventive maintenance. Meanwhile, the performance and quality components have average values of 69.08% and 99.3%, respectively, indicating that product quality is not the primary issue. Based on the fishbone diagram analysis, the main causes of low effectiveness stem from machine-related factors and work methods, leading to increased unplanned downtime.

Abstract

In the Indonesian manufacturing industry, production efficiency is a key factor in improving company competitiveness, as a significant portion of operational costs originates from material handling activities. Inefficient facility layouts often result in long material flow distances, increased processing time, and high material handling costs. This study aims to optimize the facility layout of CV CTR, a manufacturing company producing ropes and threads, which currently experiences inefficient material flow due to improper departmental arrangement. The research applies a combination of the CORELAP (Computerized Relationship Layout Planning) algorithm and the CRAFT (Computerized Relative Allocation of Facilities Technique) method. CORELAP is used to construct an initial layout based on departmental closeness relationships, while CRAFT is employed to refine the layout through iterative department exchanges to minimize material handling costs. The results indicate that the proposed layout reduces the total Material Handling Cost (MHC) from Rp912,346.84 per day to Rp692,819.43 per day, achieving a 24% reduction. This confirms that the integration of CORELAP and CRAFT effectively improves material flow efficiency and reduces operational costs.

Abstract

This study aimed to reduce transportation waste in tempeh production by integrating Lean Manufacturing tools with facility layout optimization and to evaluate the resulting operational and economic improvements. The study employed a descriptive quantitative case study conducted at a traditional tempeh production facility in Bandung, Indonesia. Waste identification was carried out using the Seven Waste framework and was prioritized using the Borda Count method. Lean tool selection was guided by the Value Stream Analysis Tool (VALSAT). Process analysis was conducted using Value Stream Mapping (VSM), Process Activity Mapping (PAM), and Root Cause Analysis (RCA). Facility layout optimization was performed using the Systematic Layout Planning framework, supported by Activity Relationship Charts and the Blocplan algorithm. Improvement effectiveness was evaluated using Future Process Activity Mapping (FPAM), Future Value Stream Mapping (FVSM), and Operator Material Handling (OMH) cost analysis. The results showed that transportation waste was the dominant inefficiency in the production system. The layout redesign reduced transportation time by approximately 57% and total material handling distance by 19%, while value-added processing time remained unchanged. These improvements generated measurable cost savings based on the OMH metric.

Abstract

Facility layout design plays an important role in improving material flow efficiency in production systems. The spun pile production workshop at PT. XYZ involves sequential processes and large, heavy materials, while the existing layout has not fully considered process sequence and material handling intensity, resulting in long material handling distances and Work in Process (WIP) accumulation. This study aims to redesign the facility layout of the spun pile production workshop at PT. XYZ using Systematic Layout Planning (SLP) and the Graph Method, and to compare the effectiveness of both methods. A descriptive quantitative approach was employed using data on facility dimensions, workstation positions, and material flow. Data analysis included evaluation of the existing layout, development of ARC, FTC, TCR, and ARD. The results show that the SLP-based layout produces a total material handling distance of 5,415.86, which is lower than the graph method layout 5,431.16 and the existing layout 5,473. Therefore, the SLP method is considered more effective in improving material flow efficiency at PT. XYZ.

Abstract

PT X is a company engaged in the natural extract industry that still faces facility layout problems in its production process, particularly in the simplisia extract production area. The existing facility layout is not arranged according to the production process sequence and the degree of closeness between departments, resulting in inefficient material flow, long material handling distances, and increased material handling costs. This study aims to redesign the production facility layout to improve material flow efficiency and minimize material handling costs. The methods used are Systematic Layout Planning (SLP) to analyze the closeness relationships between departments through the Activity Relationship Chart (ARC) and Activity Relationship Diagram (ARD), and the Computerized Relative Allocation of Facilities Technique (CRAFT) to optimize the layout quantitatively using a From-To Chart with the support of WinQSB software. The results indicate that the proposed layout improves the production process flow and reduces material handling distance and cost compared to the initial layout. The combination of SLP and CRAFT is proven to be effective in producing a more systematic, efficient, and economical production facility layout, thereby supporting increased productivity and operational efficiency at PT X.

Abstract

Efisiensi tata letak fasilitas merupakan faktor krusial dalam meminimalkan biaya penanganan material (Material Handling Cost atau MHC). Penelitian ini dilakukan pada fasilitas produksi winding trafo yang memiliki kendala inefisiensi aliran material pada tata letak awal, yang berdampak pada tingginya biaya operasional. Tujuan dari penelitian ini adalah merancang tata letak usulan yang lebih optimal untuk mereduksi jarak perpindahan dan biaya penanganan material. Metodologi yang digunakan adalah algoritma Computerized Relative Allocation of Facilities Technique (CRAFT) berbasis Microsoft Excel Add-ins yang diintegrasikan dengan Activity Relationship Chart (ARC) sebagai pertimbangan kualitatif. Hasil analisis menunjukkan bahwa tata letak awal memiliki biaya penanganan material sebesar Rp 7.220.504,5. Setelah dilakukan dua tahap iterasi dan penyesuaian berdasarkan derajat kedekatan ARC terhadap 15 departemen, dihasilkan tata letak usulan final dengan nilai biaya sebesar Rp 4.386.049. Implementasi rancangan tata letak baru ini berhasil memberikan efisiensi penurunan biaya penanganan material sebesar 39,26% dari kondisi awal. Hasil ini membuktikan bahwa integrasi algoritma CRAFT dan analisis ARC efektif dalam meningkatkan efisiensi aliran produksi dan produktivitas fasilitas.
