Abstract

Customer service quality is a key performance indicator that directly impacts a company's image. This study identified potential issues with a mobile banking app (m-banking) based on its low rating on the Google Play Store compared to similar apps. The app's rating likely reflects user satisfaction with the m-banking service. To address these concerns and improve service quality based on user feedback (voice of customer), a study was conducted using three methods: text mining, mobile banking service quality analysis, and Quality Function Deployment (QFD). The text mining method analyzed sentiment from comments on the Google Play Store. It employed a Support Vector Machine (SVM) algorithm, achieving high accuracy (0.86), precision (0.86), recall (0.84), F1-score (0.85), and AUC (0.84). Negative sentiment analysis identified five dimensions encompassing 15 attributes of m-banking service quality. These attributes were then incorporated into a questionnaire distributed to 100 respondents. Six attributes with the lowest gap values were identified as priority attributes, representing the most critical customer concerns. These attributes were used as the "voice of the customer" in the QFD method. By constructing a House of Quality (HoQ) matrix, the study established a priority ranking of technical responses. These responses include strategies to optimize tools, application features, and memory usage, reduce excessive animation and the use of live wallpapers, create an update mechanism, provide content localization features, continuously incorporate customer feedback into application improvements.

Abstract

This study investigates risk mitigation strategies within the label holder supply chain at a company specializing in convection-produced label holders. The House of Risk approach will be used to identify and prioritize potential risks and their sources throughout the supply chain activities, as defined by the Supply Chain Operation Reference (SCOR) method. Common supply chain risks include torn mica, detached stitches, and improper strap lengths. The risk identification process within the label holder supply chain activities resulted in 30 risk events, 27 risk agents, and 13 prioritized risk mitigation actions. These actions include regular routine machine maintenance, employee briefings, identifying backup suppliers, consistent performance monitoring, station coordination before production, machinery and tool upgrades for quality assurance, yearly shutdowns/maintenance, establishing customer contracts, user feedback coordination, training for raw material receiving personnel, implementing periodic product testing, enacting efficient inventory management practices, and improving finished goods quality management.

Abstract

As time progresses, the evolving industrial world demands that companies devise the best strategies to achieve their desired goals. A well-designed system is expected to increase the profitability of the company itself. CSD is an interior furniture and interior design studio located in the city of Cilegon, Banten. The challenge faced by CSD is the inability to meet order deadlines during periods of high demand. The objective of this study is to assess the level of machine utility within the existing process and provide recommendations to achieve an optimal process. The methodology employed includes system simulation and model development using Promodel software. Additionally, statistical tests, model validation, and ANOVA tests were conducted. Based on the results, it was determined that the level of machine utility at CSD is 17.48% for shaping planning, 30.08% for grinding, 14.88% for assembly, and 29.98% for finishing. The proposed solution, scenario or proposal 2, suggests combining the assembly and finishing workstations, resulting in increased machine utility.

Abstract

The Central Statistics Agency of Indonesia (BPS) has recorded an increase in the use of liquefied petroleum gas (LPG) by the public over the last seven years. This increase is due to the government changing its policy from using fuel oil to LPG. LPG is essential for the community as a kitchen fuel to meet their needs and for resale. Distributing LPG gas is crucial to meeting the community's needs. However, one of the distribution processes involves manual loading and unloading, which can cause musculoskeletal complaints. Therefore, tools that can facilitate work are necessary. This study aims to reduce the risk of musculoskeletal disorders by examining the working posture of transporting LPG gas at a LPG distributor in Indonesia. The study proposes a tool design to solve the problem of high work posture. The results of data processing and analysis show that the design of assistive devices can reduce the risk of work posture.
