Abstract

Increasing competition in the culinary industry requires companies to better understand and enhance customer satisfaction as a key factor for business success. This study analyzes the level of customer satisfaction and identifies the factors influencing it in J.CO Donuts & Coffee products in Purwakarta. The independent variables include product quality, price, service quality, cleanliness, and service speed, while the dependent variable is customer satisfaction. This research employs a quantitative approach using a survey method through questionnaires distributed to customers, measured using a Likert scale. The data were analyzed using SPSS, including validity and reliability tests, multiple linear regression, t-test, F-test, and coefficient of determination. In addition, a weighting method was applied to determine the relative importance of each variable. The results indicate that all variables significantly influence customer satisfaction, both partially and simultaneously, with the dominant variable determined based on the highest weighting score as a priority for service improvement.

Abstract

Product quality is an important factor in maintaining customer satisfaction and business competitiveness. This study aims to improve the quality control of milk sticky rice products by applying Statistical Quality Control (SQC) and the Plan-Do-Check-Act (PDCA) method. Production and defect data collected from December 2025 to May 2026 were analyzed using check sheets, control charts, Pareto diagrams, and cause-and-effect diagrams to identify dominant defects and their root causes. The PDCA cycle was then implemented to develop and evaluate improvement actions. The results indicate that the dominant defects were hard sticky rice, soft sticky rice, poor product presentation, and inconsistent taste. The main causes originated from human factors, work methods, raw materials, and production processes. The implementation of improvement actions through the PDCA approach enhanced process control and reduced the defect rate, resulting in more consistent product quality. This study provides practical recommendations for implementing continuous quality improvement in food production businesses.

Abstract

Objective: This study analyzes the maintenance effectiveness of the Bagging machine at PT Pupuk Kujang Cikampek using Overall Equipment Effectiveness (OEE) and Six Big Losses, and proposes improvement recommendations. Methods: A quantitative descriptive approach was used. Data were collected through observation, interviews, documentation, and literature review from May 2025 to April 2026. Availability, Performance, and Quality were calculated to determine OEE, while Six Big Losses, Fishbone Diagram, and 5W+1H were applied to identify root causes. Results: The average Availability, Performance, and Quality values were 93.88%, 69.13%, and 99.47%, producing an OEE of 64.48%, below the 85% world-class standard. The dominant losses were Reduced Speed Losses (35.18%) and Idling and Minor Stoppages (29.06%). Novelty: This study integrates OEE and Six Big Losses using one year of operational data to support preventive maintenance recommendations. These findings help prioritize maintenance actions to improve machine reliability, production continuity, and overall plant efficiency in practice.

Abstract

This study aims to analyze product failures and propose improvement actions for cabinet products at CV. Arafah Jaya Purwakarta. Based on production data from November 2024 to April 2025, cabinet products showed the highest defect rate compared to other products, reaching 13%. The most common defects include wood cracks, warped wood, and brittle wood. Failure Mode and Effect Analysis (FMEA) was applied to identify and prioritize potential failures based on the Risk Priority Number (RPN), while Fault Tree Analysis (FTA) was used to systematically determine the root causes of failures. The analysis results indicate that the main causes of defects are related to substandard raw material quality, environmental conditions, and insufficient supervision during the production process. Based on the results of FMEA and FTA, improvement proposals were developed using the 5W+1H approach, focusing on improving raw material selection, controlling wood storage conditions, and enhancing work procedures and production supervision. These improvement efforts are expected to reduce defect rates and improve the overall quality of cabinet products.
