Dr. Saiful Anwar Malang is a state hospital has done it is job and function, but in 3rd class of pavilion room, the number of patient decrease dramatically. It is concerned with quality of this hospital. To answer this problem, research was done using Quality Function Deployment (QFD). Quality Function Deployment is a tool which design some needs include customers represented as a voice of customer and including some competitions and also groups some activities that usually called affinity graphic ang getting a benchmarking for it is competition. From the result analysis can be showed that main attribute for patience is a accuracy. And from House Of Quality can be found that getting a periodic meeting to evaluate this hospital and also increase a service can be made 20 concept

Abstract

Although inventory management is essential for competitiveness, limited research exists on process-based redesign of internal material flow between warehouse and assembly units in manufacturing operations. This study presented a new approach to material flow between warehouses and assembly shops in manufacturing, examining inefficient resource utilization caused by prolonged internal logistics processes, including incorrect deliveries, data entry errors, and demand irregularities. The aim of the study was to identify and eliminate all factors that can prevent the material flow between the warehouse and assembly units from being completed within the specified time. This analysis identified bottlenecks and inefficiencies that negatively affected productivity. The improvements reduced handling times from warehouse to assembly by 10% and standardized the process. Manual errors were minimized, traceability of material flows was improved, and flexibility and responsiveness of business processes were increased. These results offered practical insights for manufacturing managers seeking to redesign internal logistics processes using lean tools. The study also contributed to the limited empirical literature on intra-facility material flow optimization. Managers could adopt the proposed process design to increase responsiveness and reduce operational errors in similar manufacturing environments. Future research was suggested to explore the integration of this approach into other logistics activities.

Abstract

Small and medium-sized manufacturing enterprises (SMEs) operating under make-to-order (MTO) systems frequently experience productivity and occupational health issues due to misalignment among organizational, technical, and human factors. This study applies the Macro-Ergonomic Analysis and Design (MEAD) framework to systematically diagnose and improve a manufacturing work system from a sociotechnical perspective. A descriptive, qualitative approach was employed, utilizing interviews, questionnaires, and workplace observations that involved production workers and management. The ten stages of MEAD were implemented to identify critical variances, analyze interactions between subsystems, and develop prioritized improvement alternatives. The results indicate that unfavorable physical environmental conditions—particularly excessive heat and noise—constitute dominant systemic variances that contribute to employee fatigue, work stress, and reduced operational effectiveness. Based on a structured evaluation of alternatives, integrated improvement strategies emphasizing environmental control, risk awareness, and organizational support were proposed. This study demonstrates the usefulness of MEAD as a holistic and adaptive framework for redesigning work systems in SMEs. It contributes empirical evidence to the limited macro-ergonomics literature in MTO manufacturing contexts, particularly in developing countries.

Abstract

This study addresses the lack of integrated frameworks explaining how organizational safety culture influences individual safety behavior in small-scale industrial settings. The research aims to develop a structural model where organizational commitment mediates the relationship between safety culture and safety behavior. A quantitative survey was conducted in a briquette manufacturing firm involving 130 production workers. Data were collected using validated questionnaires and analyzed using Structural Equation Modeling (SEM) with AMOS software. The model demonstrated satisfactory fit indices (CFI = 0.957; RMSEA = 0.059), and mediation analysis via bootstrapping confirmed that organizational commitment fully mediates the effect of safety culture on behavior. These findings highlight that improving safety behavior requires more than formal procedures; it depends on the internalization of shared cultural values through commitment. The study contributes to the development of diagnostic and intervention models for enhancing worker safety in labor-intensive industrial settings.

Abstract

The adoption of e-procurement systems in the upstream oil and gas industry remains challenging due to operational complexity, stringent regulatory requirements, and high technological demands. This study investigates the success factors that influence adoption and effectiveness by integrating three theoretical perspectives: the Technology Acceptance Model (TAM), the Unified Theory of Acceptance and Use of Technology (UTAUT), and the DeLone & McLean Information Systems Success Model. A systematic literature review of 62 peer-reviewed articles was conducted to synthesize evidence from user, system, and organizational levels. The results indicate that user acceptance constructs such as perceived usefulness, ease of use, and trust must be complemented by system quality, information accuracy, and user satisfaction, alongside organizational support factors including leadership commitment, infrastructure readiness, and facilitating conditions. Findings demonstrate that fragmented approaches focusing solely on user behavior or system performance are insufficient in the oil and gas sector, where organizational and technical environments critically shape adoption. To address this gap, the study proposes an integrated conceptual framework linking user, system, and organizational dimensions. The framework provides actionable insights for procurement professionals, system developers, and policymakers to enhance digital procurement performance in complex, high-risk contexts.

Abstract

This research developed a Vendor Managed Inventory (VMI) model for a three-echelon supply chain consisting of multiple suppliers, one manufacturer, and multiple buyers. The study aimed to optimize total system profit under deterministic demand and industrial constraints. Strategic interactions among actors were modeled using Vertical Nash and Stackelberg game frameworks, and the resulting nonlinear optimization problem was solved using the grey wolf optimizer algorithm. The results indicated that the Vertical Nash game produced higher total profit than the Stackelberg game. Profit distribution reached 6.78% for suppliers, 39.60% for the manufacturer, and 53.62% for buyers under the Vertical Nash game, while the Stackelberg game produced shares of 11.50%, 24.37%, and 64.14%, respectively. These findings demonstrated that decision structure significantly affected system performance and profit allocation in integrated supply chains.
