Total Quality Control (TQC) Analysis in Identification of Damage to Coffee Production at PT XYZ
Get PDFPT XYZ is a coffee processing company with a production process involving five stages: sorting, drying, peeling, selecting, and packaging coffee beans. This study applies the Total Quality Control (TQC) approach to identify factors causing product defects. Methods include p-control charts to monitor quality variations statistically and fishbone diagrams to analyze root causes. Data were collected through interviews, observations, and company documents. The analysis revealed seven data points exceeding the upper control limit (UCL) and 11 below the lower control limit (LCL). Human errors, inadequate training, and machine-related issues were identified as the primary causes of defects. Environmental factors, such as inconsistent humidity levels, were also found to affect product quality. The findings provide actionable insights for PT XYZ to implement Kaizen-based improvements, focusing on minimizing defects, enhancing production quality, and maintaining product consistency. These measures are expected to support the company in achieving better control over quality processes and ensuring the stability of its coffee product standards
Risk Assessment of Productivity Recovery Post Occupational Accident in Indonesia
Get PDFIndonesia's public health provider, the Insurance Administration Organization (IAO), provides universal coverage for Work Accident Insurance. As an initiative, it has failed to support all workers. This study assesses productivity recovery risks and associated future costs following occupational accidents, employing risk management methods and scenario analyses to aid decision-making in Indonesia. Focusing on formal workers in Surabaya, this research examines the balance between government benefits and expected productivity rebound upon return. Six risk types are identified and analysed, while the most prevalent risks involve workers still undergoing treatment with uncertain outcomes. As existing coverage schemes risk negative cash flow and deficits, this study also calculates the budget needed for zero-accident targets and maximum compensation to balance government obligations and workers' remuneration. This study has successfully captured the critical factors that can lead to refining coverage and addressing financial shortfalls, allowing improved support for workers' recovery and return productivity
Measurement of Relative Efficiency Using Data Envelopment Analysis (DEA) Method to Improve Efficiency in Perum Pegadaian Syariah
Get PDFThe development of the Islamic financial industry which includes banking, insurance and pawnshops is basically a very long historical process. Perum Pegadaian Syariah, as one of the state-owned enterprises, is faced with the challenge of competing and improving efficiency in the growing Islamic financial industry. This study aims to measure the operational efficiency of Islamic Pawnshops in East Java Province using the Data Envelopment Analysis (DEA) method. This study identifies the relative efficiency of each Pawnshop unit from several branches of Pegadaian Syariah, including Joko Tole, Babakan, Sidokare, Mayjend Sungkono, and Blauran. The results showed that four branches were efficient with a relative efficiency value of 1, while Sidokare branch showed inefficiency with a value of 0.908. Improvement recommendations for Sidokare branch include reducing service time, operating costs, and increasing the number of customers and collateral. This research is expected to guide Perum Pegadaian Syariah in contributing to improving efficiency and competitiveness in an increasingly competitive market

THE EFFECT OF CARGO MANAGEMENT, FACILITY MANAGEMENT, AND INFORMATION MANAGEMENT MODERATED BY SECURITY CULTURE ON SUPPLY CHAIN SECURITY OPERATIONAL PERFORMANCE ON THE DELIVERY OF DORE BULLION BY GOLD MINING COMPANIES IN INDONESIA
Get PDFGold mining companies in Indonesia must refine gold from dori bullion in Jakarta, which faces various risks, including theft. This study examined the effect of cargo management, facility management, and information management on supply change security operational performance moderated by security culture in gold mining companies in Indonesia. The type of research used is causality research, which is a hypothesis to test the effect of a variable on another variable. The variables used consist of 3 independent variables: cargo management, facility management, and information management; 1 moderating variable, security culture; and 1 dependent variable, supply change security operational performance. The sample withdrawal method uses purposive sampling, namely respondents who work in gold mining companies related to the supply chain for sending Dori bullion. The sample used was 160 respondents, and the analysis tool was SEM-PLS. The findings show that cargo management, facility management, and information management are proven to have a positive effect on supply change security operational performance, while security culture is not proven to moderate the influence of cargo management, facility management, and information management on supply change security operational performance.

Integrating QFD and TRIZ for the Development of a Safe and Sustainable Lunch Box Design
Get PDFThis study addresses the critical need to design a safe and functional food storage solution by re-engineering a lunch box product based on consumer requirements. The research problem centers on the prevalent use of harmful materials like BPA and lead in existing products, which poses health risks to users. Our methodology combines Quality Function Deployment (QFD) and the Theory of Inventive Problem Solving (TRIZ) to tackle this issue. QFD was used to transform detailed customer needs, identified through a Voice of Customer (VOC) survey, into specific technical specifications. The resulting House of Quality (HoQ) revealed two primary contradictions: one between ensuring food-grade material safety and offering a product warranty, and another between using high-quality, safe materials and maintaining an affordable price. To resolve these conflicts, TRIZ principles, specifically Cheap Short-Living Objects and Composite Materials, were applied. This approach led to a product design that is not only robust and practical, with features such as high-density seals and segregated compartments, but also scientifically sound in its use of safe materials. The findings demonstrate a successful integration of market needs and creative problem-solving to develop a product that is both commercially viable and fundamentally safer for consumers
IMPLEMENTATION OF A FINANCIAL RECORDING SYSTEM WEBSITE BASED ON DAPOER LN MSME KUDUS
Get PDFThis research aims to implement a website-based financial recording system at Dapoer LN MSME Kudus, with a focus on increasing efficiency and accuracy in recording income and expenses. The system is designed to support the management of data such as income, expenses, payables, receivables, and employee data in real-time, with a simple and user-friendly interface. The implementation process uses the PHP programming language and the waterfall development method, which was chosen for its systematic linear approach so that each stage can be managed in a structured manner. The system development was performed using Visual Studio Code as the Integrated Development Environment (IDE) and MySQL as the Relational Database Management System (RDBMS). Visual Studio Code was chosen for its flexibility and extension support, while MySQL was used for its stability in handling small to medium scale data. The results of the research resulted in a website-based financial recording system that is able to manage data on income, expenses, payables, receivables, and employee data with a high level of accuracy. This system is expected to support Dapoer LN MSME Kudus in monitoring financial conditions more effectively and provide a basis for making quick and precise decisions. This article covers the entire process of designing to evaluating the system, with the hope of contributing to the increased productivity and growth of Dapoer LN MSME Kudus. In addition, this system is expected to be a reference for other MSME in improving competitiveness and operational efficiency. Thus, this research is not only beneficial for Dapoer LN MSME Kudus, but also has the potential to have a broader positive impact on the small and medium business sector.
