Abstract

This study examines the implementation and effectiveness of Total Quality Management (TQM) practices within Nigeria’s beverage industry, focusing on eight critical factors: management leadership, quality department, training, product/service design, supplier quality management, process management, quality data and reporting, and employee relations. Data were collected from 92 respondents across five leading beverage companies using a validated questionnaire based on Black and Porter’s (2007) TQM framework. Descriptive analysis using IBM SPSS Statistics Grad Pack revealed that the overall level of TQM practice in the industry is moderate. Strengths were identified in the visibility and coordination of the quality department, process automation, and top management’s commitment to training. However, significant gaps exist in supplier quality management, availability and utilization of quality data, and employee involvement in quality decisions. The findings indicate that while foundational TQM elements are in place, strategic areas critical for achieving comprehensive quality excellence remain underdeveloped. The study underscores the importance of closing performance gaps through better supplier integration, data-driven decision-making, and enhanced employee feedback mechanisms. This research contributes to the understanding of TQM implementation challenges in emerging markets and provides practical insights for improving quality performance in Nigeria’s beverage sector.

Abstract

PT Gapura Angkasa Yogyakarta International Airport provides ground handling services, including baggage services. The Lost and Found Unit plays a crucial role in handling passenger complaints related to lost or damaged baggage. However, problems are still frequently encountered in handling these complaints, which impact passenger satisfaction. This is thought to be related to unprofessional employee performance, particularly in terms of friendliness, responsiveness, and communication skills. The lack of training and briefings also impacts the quality of service provided. This study aims to determine the effect of Lost and Found Unit employee performance on passenger satisfaction. The approach used was a quantitative survey method with 96 respondents. The analysis technique used was simple linear regression to determine the extent of employee performance's influence on passenger satisfaction. The results showed a significant effect between employee performance and passenger satisfaction, with a t-value of 9.739 and a significance level of 0.000. The beta coefficient of 0.709 indicates a strong and positive relationship, while the R² value of 0.502 indicates that 50.2% of the variation in passenger satisfaction is influenced by employee performance. These findings emphasize the importance of improving employee professionalism, skills, and friendliness in efforts to improve passenger satisfaction with baggage handling services at the airport.

Abstract

This study aims to identify and quantify wood waste produced during the machining of solid wood components using kiln dried Durio zibethinus boards. A descriptive quantitative approach was employed to measure the volume and weight of waste generated at each production stage, including ripping, crosscutting, planing, and thicknessing. Sampling was conducted using a precision digital scale to collect and compare the actual and theoretical waste. The results indicate that only 43% of the raw material volume was utilized in finished components, while 57% was lost as waste, primarily in the form of sawdust, shavings, and offcuts. The thicknesser contributed the largest proportion of waste (58%), followed by the ripsaw (21%), single planer (20%), and jumpsaw (1%). These findings highlight the need for improved raw material selection, more efficient cutting list design, enhanced nesting strategies, and better machine calibration. Implementing these practices can reduce wood waste, improve material efficiency, and minimize occupational exposure to wood dust in furniture manufacturing

Abstract

This study evaluates the use of Paper Mill Sludge (PMS) waste as a partial replacement for fine aggregate in paving block production, focusing on compressive strength and economic feasibility. PMS was incorporated at 0%, 5%, 10%, 15%, and 20% of the total fine aggregate weight. Compressive strength tests followed the Indonesian National Standard (SNI 03-0691-1996), accompanied by production cost analysis. The results showed that 5% PMS achieved the highest compressive strength of 264.23 kg/cm², about 7.7% higher than the control 258.71 kg/cm², meeting the SNI quality class B (K200) standard. Meanwhile, 10% PMS reduced production costs by 6–8% while still satisfying the minimum requirement for K200 paving blocks (category B). This demonstrates a clear trade-off between mechanical performance and cost efficiency, where 5% PMS ensures maximum strength, while 10% PMS provides adequate strength with economic benefits. At lower levels, PMS fibers improved cement–aggregate bonding and reduced voids, whereas higher dosages (>10%) disrupted hydration and lowered strength. Practically, PMS utilization offers the paving block industry a sustainable and cost-effective alternative that reduces reliance on natural aggregates, supports waste valorization, and aligns with SNI standards for applications such as parking lots.

Abstract

This research aims to design and build an environmentally friendly burner that integrates used oil as a fuel based on water vapor pressure and to test the waste combustion efficiency using the designed device. The design stage of the device uses the assistance of AutoCAD. This is followed by direct experimental testing to collect data on the performance and efficiency of waste combustion in the burner. Based on the results of the two burners that have been tested above, it can be concluded that the amount of shrinkage of 8 kg of waste burned in a used oil burner with water vapor pressure is more shrinkage than the used oil burner without water vapor with a difference of 1.1 kg. This can be proven in the best experimental results in the first experiment, namely to burn 8 kg of waste in 25 minutes experiencing a shrinkage of 7.1 kg, so that the efficiency of waste combustion reaches 88.75% in a used oil burner with water vapor pressure. While the used oil burner without water vapor obtained the best results for burning 8 kg of waste in 25 minutes experiencing a shrinkage of 6 kg, so that the efficiency is 75% lower than combustion using a used oil fuel burner using water vapor pressure.
