This study aimed to analyze the influence of workload and burnout on nurses’ sleep quality while controlling for age, gender, and education as potential confounding variables. A quantitative analytic study with a cross-sectional design was conducted among 156 nurses working in a private hospital in Depok City. Data were collected using a workload questionnaire, the Maslach Burnout Inventory (MBI), and the Pittsburgh Sleep Quality Index (PSQI). The data were analyzed using Chi-Square tests and multiple logistic regression. The findings showed that both workload and burnout had significant effects on sleep quality (p < 0.05), with burnout identified as the most dominant factor. Age and gender were also significantly associated with sleep quality, whereas education did not show a statistically significant effect. The regression model demonstrated excellent fit, indicated by a McFadden pseudo R² value of 0.908. These results suggest that occupational factors, particularly burnout, play an important role in determining nurses’ sleep quality. Therefore, effective stress reduction and workload management strategies are needed to support nurses’ well-being and improve sleep quality.

However, the magnitude of the effect is substantially stronger in Singapore, indicating higher regulatory efficiency and institutional effectiveness in translating policy interventions into tourism demand. These results support institutional and tourism demand theories, emphasizing that regulatory quality, rather than regulatory volume, is a key determinant of tourism performance. The study contributes to the tourism policy literature by providing cross-national empirical evidence on regulatory impacts and highlighting the importance of governance capacity in tourism development. From a policy perspective, the findings suggest that countries should prioritize regulatory coherence, administrative efficiency, and adaptive governance to enhance tourism competitiveness and resilience.

Sugarcane cultivation often faces productivity losses due to poor sprouting and non-uniform initial growth. In bud-based nursery systems, seedling quality is heavily constrained by limited media volume and low buffering capacity. This study aimed to evaluate the synergistic effects of NPK fertilizer dosages and Gibberellic Acid (GA) concentrations on the growth and physiological vigor of sugarcane seedlings. The experiment was conducted using a Completely Randomized Design featuring nine treatment combinations with four replications. Parameters measured included plant height, stem diameter, the number of tillers, the number of leaves, and the chlorophyll index. The results demonstrated that the application of the NPK 150 kg ha⁻¹ + GA 50 ppm treatment significantly enhanced plant height, stem diameter, number of shoots, and the number of leaves compared to the control treatment. Statistical analysis revealed a significant interaction between nutrient availability and hormonal stimulation in overcoming the constraints of limited rooting environments. These findings suggest that precise integration of chemical fertilization and exogenous growth regulators is essential for producing high-quality planting material, potentially reducing losses in the subsequent planting cycle. In the future, it is necessary to confirm the use of a combination of NPK fertilizer with gibberellin during the vegetative period of plants so that the information obtained is comprehensive.

This study aims to analyze the quality control of car tire production at Company X using the Statistical Process Control (SPC) method. The data used in this research are secondary data obtained from GitHub, consisting of weekly production and defect data observed over one year with a total of 52 observations. The analysis was carried out using descriptive statistics, histograms, P-charts, and cause-and-effect (Ishikawa) diagrams. The histogram results indicate that the distribution of defects is right-skewed, showing that most defects occur at a moderate level, although several extreme values are present. The initial P-chart analysis revealed several points below the lower control limit, indicating the presence of special cause variation and suggesting that the production process was not fully stable. After removing out-of-control data and recalculating the control limits, the revised P-chart showed that all data points were within the control limits, indicating that the production process was statistically under control. Furthermore, the Ishikawa diagram identified potential causes of defects related to human factors, machines, methods, materials, and the working environment. Overall, the results demonstrate that SPC is an effective tool for monitoring production stability and providing a systematic basis for improving quality consistency in car tire manufacturing processes.

This study aims to analyze the factors affecting real wages of construction workers across provinces in Indonesia from 2010 to 2023 using panel data analysis. The independent variables include Provincial Minimum Wage (UMP), Consumer Price Index (CPI), Open Unemployment Rate (TPT), and Performance Pay (Balas Jasa). A panel dataset of 476 observations from 34 provinces over 14 years was analyzed using three model approaches: Common Effect Model (CEM), Fixed Effect Model (FEM), and Random Effect Model (REM). The best model was determined through Chow Test, Hausman Test, and Lagrange Multiplier Test, which confirmed that the Fixed Effect Model (FEM) is the most appropriate for analyzing this research data. FEM estimation results show that simultneously, all independent variables (UMP, CPI, TPT, and Performance Pay) have a significant effect on real wages with an F-statistic value of 436,465.9 (p-value = 0.0000 < 0.05), indicating that the model as a whole is highly valid and capable of explaining the variation in real wages collectively. However, partial tests reveal that only the Real Wage variable has a positive and statistically significant effect on Performance Pay (coefficient = 106.3320; t-statistic = 1276.083; p-value = 0.0000), while UMP (p-value = 0.1472), CPI (p-value = 0.6460), and TPT (p-value = 0.6934) show no significant effects at the 5% significance level. The research model demonstrates very high predictive ability with an R-squared value of 0.999735 (99.97%), indicating that the variables studied can explain nearly all variation in real wages of construction workers at the provincial level. This research provides policy implications that improving real wages in the construction sector requires an integrated approach that focuses not only on minimum wage setting but also on regional inflation control, human capital quality improvement, and creating conducive labor market conditions through unemployment reduction

From a managerial perspective, these findings provide practical guidance for improving manufacturing quality through enhanced process control, equipment maintenance, and workforce capability development.

The International Maritime Organization (IMO), as one of the key organizations contributing to the reduction of carbon emissions in the maritime sector, offers several options that maritime industry stakeholders can utilize to measure carbon emissions, one of which is calculating the Energy Efficiency Operational Indicator (EEOI). The statistical x-bar control chart, employed as a monitoring instrument for the EEOI quality parameter, indicates that one container ship trip recorded an EEOI value of 0.00104, which exceeded the upper control limit of 0.00098. The results of process capability analysis on the initial dataset sample revealed that the value of Cp < 1, indicating that energy efficiency performance was not satisfactory. Process control was subsequently applied by eliminating anomalous data, which demonstrated a potential reduction in fuel consumption and EEOI by approximately 25%, as reflected in the improvement of the Cp value. The potential for enhancing the ship’s operational capability, however, still requires further control measures to improve energy efficiency performance. The reduction in fuel consumption directly contributes to lower emission levels, thereby supporting the realization of a sustainable shipping industry.

This study aims to analyze product quality at PT. XYZ, particularly focusing on Defects by Dimension, using the Statistical Quality Control (SQC) method. Defect data were collected over the period from April 2024 to March 2025 and analyzed using seven SQC tools, namely the check sheet, histogram, Pareto Chart, Scatter Diagram, and p-Chart. The results indicate that Defects do not always increase in proportion to production volume, and the most dominant types of Defects are Dimensional and Hole Distance, accounting for 73.4% of the total Defects based on the Pareto Chart. The Scatter Diagram shows an upward trend in Defects as production increases up to a certain point, after which the Defect rate decreases as production continues to rise. The p-Chart indicates that the production process remains within statistical control limits, although several samples approach or slightly exceed the upper control limit. Overall, the quality control process is fairly well maintained; however, greater attention is needed to address dominant Defect types and variations near control limits to prevent larger process deviations.
