Abstract

General Background Industrial manufacturing systems require stable production processes to maintain productivity and product quality. Specific Background PT. XYZ experiences significant production delays in liquid glucose processing due to machine performance degradation, raw material issues, employee factors, and consumer-related constraints, resulting in a production decrease of up to 20% from the daily target. Knowledge Gap Previous studies tend to analyze production delays separately, lacking an integrated approach combining root cause identification, risk prioritization, and decision-making. Aims This study aims to identify the causes of production delays, evaluate failure risks, and determine optimal corrective actions using Fishbone Diagram, Failure Mode and Effects Analysis (FMEA), and Analytical Hierarchy Process (AHP). Results The findings indicate that machine maintenance issues and external factors are dominant causes, with the highest Risk Priority Number (RPN) identified in the filtration and ion exchanger process (192). AHP analysis shows that dismantling and repairing the heating pipeline is the top-priority solution with a weight of 67.4%. Novelty This study integrates Fishbone, FMEA, and AHP methods to provide a structured and multi-criteria decision-making framework in glucose production systems. Implications The results support improved maintenance planning and production management strategies to reduce delays and maintain operational stability in manufacturing environments. Keywords: Production Delay, Glucose Manufacturing, Risk Analysis, FMEA, AHP Key Findings Highlights Critical failures identified in filtration system with highest risk ranking Multi-method integration enables structured decision prioritization Pipeline repair strategy becomes dominant corrective action

Abstract

General Background Condensers play a crucial role in thermal systems by converting steam into liquid through heat transfer processes. Specific Background The performance of condensers is influenced by key parameters such as pressure, temperature, and fluid flow rate, particularly in finned tube systems.

Aims This study aims to analyze the efficiency and heat transfer rate of a Pokka 5001 condenser using pressure variations as the primary variable. Results Experimental results show that increasing pressure from 20 to 40 Psi leads to higher efficiency values, ranging from 73.17% to 89.68%, and improves heat transfer rate and fluid work. Additionally, higher flow rates contribute to increased heat transfer performance. Novelty This study provides experimental evaluation of a Pokka 5001 finned tube condenser with controlled pressure variation and airflow conditions. Implications The findings support better operational control of pressure and flow rate to maintain optimal condenser performance in thermal systems. Keywords: Condenser Pressure, Heat Transfer, Efficiency Analysis, Finned Tube, Thermal System Key Findings Highlights Efficiency increases consistently with rising operating pressure Flow rate growth correlates with higher thermal transfer performance Experimental data identify optimal operating conditions

Abstract

General Background Shrimp cracker production requires strict quality control, particularly in moisture content, which determines texture, shelf life, and defect occurrence. Specific Background In industrial practice, defects such as mold growth remain a critical issue due to suboptimal drying and process control conditions. Knowledge Gap Previous studies have not fully integrated process optimization and root cause identification to address both quality parameters and defect sources simultaneously. Aims This study aims to optimize drying parameters and identify root causes of defects using Response Surface Methodology (RSM) and Root Cause Analysis (RCA). Results The optimal conditions were obtained at a temperature of 70°C, drying time of 60 minutes, and thickness of 5 mm, producing a moisture content of 9.00% with a desirability value of 1.00. RCA findings indicate that mold defects are caused by high raw material moisture, inadequate storage conditions, and limited production supervision. Novelty This study integrates RSM-based parameter optimization with RCA-based defect analysis within a single framework. Implications The results provide practical recommendations for improving production control, reducing defects, and maintaining consistent product quality in shrimp cracker manufacturing. Keywords: Shrimp Cracker, Process Optimization, Moisture Content, Response Surface Methodology, Root Cause Analysis Key Findings Highlights Optimal drying parameters identified through statistical modeling approach Major defect source linked to raw material and process control conditions Integrated analytical framework supports systematic quality improvement
