Abstract

The oil and gas industry is a strategic sector that requires systematic approaches in workplace management through Good Housekeeping and occupational safety implementation to achieve optimal business performance. This study aims to comprehensively analyze the influence of Good Housekeeping and occupational safety implementation on business performance at PT Kilang Pertamina Internasional (KPI) RU III Plaju. The research employed a quantitative approach with random sampling technique involving 125 respondents from a population of 919 employees. Data were collected through Likert scale questionnaires and analyzed using Structural Equation Modeling with Partial Least Squares (SEM-PLS) and multiple linear regression through SPSS 30. The results demonstrate that Good Housekeeping significantly influences occupational safety (t-value 6.877 > t-table 1.979; p = 0.000) with regression coefficient of 0.383. Occupational safety shows highly significant influence on business performance (t-value 15.844 > t-table 1.979; p = 0.000) with regression coefficient of 1.013 and explains 76.9% of business performance variation. Good Housekeeping also directly influences business performance (t-value 2.215 > t-table 1.979; p = 0.029) with regression coefficient of 0.103. This study confirms that integrated implementation of Good Housekeeping and occupational safety provides dual benefits through simultaneous improvement of occupational safety and business performance, with recommendations for developing comprehensive and sustainable implementation strategies.

Abstract

This study aims to determine the influence of leadership style and the implementation of Living Core Values (LCV) AKHLAK culture on business performance at PT KPI RU V Balikpapan. This research employed a quantitative approach with a sample of 100 respondents. The data analysis methods included validity testing, reliability testing, classical assumption testing, regression analysis, coefficient of determination analysis, path analysis, and hypothesis testing. The results of the study show that, partially, leadership style has a significant effect on business performance, with a t-value of 2.762 ( > t-table value of 1.985) and a p-value of 0.007 ( < 0.05). Likewise, the implementation of the LCV AKHLAK culture has a significant effect on business performance, with a t-value of 6.367 (> t-table value of 1.985) and a p-value of 0.000 ( < 0.05). Simultaneously, leadership style and the implementation of the LCV AKHLAK culture influence business performance, as indicated by an F-count value of 69.092 ( > F-table value of 3.09) and a p-value of 0.000 ( < 0.05). This is further supported by the coefficient of determination of 0.588, meaning that both variables explain 58.8% of the variance in business performance, while the remaining 41.2% is influenced by other factors not observed in this study. PT KPI RU V Balikpapan needs to integrate leadership development and the AKHLAK culture into its management strategies, as both factors significantly impact business performance. By strengthening these two aspects, it is expected that business performance can be further optimized.

Abstract

The impact of Holding and Subholding Implementation is expected to provide significant improvement in employee performance as well as optimization of profits and operations as well as cost efficiency for PT KPI. The company's performance becomes faster, more agile, and concise in the decision-making process. This study uses a quantitative research method with primary data sources through a questionnaire with a five-point Likert scale. The respondents in this study were 84 employees at PT KPI in all KPI offices and Refinery Units (RU) of PT KPI, with a sampling technique of simple random sampling (SRS). The data analysis technique uses Spearman correlation analysis to test the strength of the relationship between two variables. The relationship between the Holding and Subholding Implementation variables with employee performance has a correlation of 0.704 and the relationship between the Holding and Subholding Implementation variables with employee performance achievement is 0.798. These figures indicate that the Holding and Subholding Implementation variables have a strong influence on employee performance variables and their performance achievements. In the non-parametric analysis of the Kruskal-Wallis test, the results showed that there were significant differences between groups of variables in the holding and subholding implementation at PT KPI on employee performance and its achievements. This is indicated by the p-value in the Kruskal Wallis test of 0.00, which indicates a significant influence on the implementation of holding and subholding at PT KPI on employee performance and achievements. The results of a simple linear test show that every increase in one unit of value for the Implementation of the structure (holding and subholding) will increase 0.767 units of the value of employee performance achievement at PT.KPI employees with free implementation of the structure has a contribution effect of 67.3% on the employee performance achievement variable.

Abstract

This study aims to examine the influence of workload and fatigue on operator productivity at the Paraxylene Refinery of PT Kilang Pertamina Internasional RU IV Cilacap. Using a quantitative research method and a causal associative approach, data were collected via questionnaires from 64 employees selected through simple random sampling. The data were analyzed using multiple regression and path analysis techniques. The results indicate that workload has a significant positive direct effect on productivity, but a negative indirect effect through fatigue. Fatigue was found to have a significant negative impact on productivity and acts as a mediating variable in the relationship between workload and productivity. Simultaneously, workload and fatigue contribute 61.2% to variations in productivity. This study contributes to the literature by confirming fatigue as a significant mediator affecting operator performance in high-risk industrial settings.

Abstract

Digitalization has become a major catalyst in business transformation, including in the oil and gas sector, which has high operational complexity. This study aims to analyze the influence of digitalization on business process innovation and organizational performance at PT Kilang Pertamina Internasional (KPI) Refinery Unit (RU) VI Balongan, one of the strategic refineries in Indonesia. This study uses a quantitative approach with an explanatory research design. Data were collected through questionnaires distributed to 122 employee respondents at PT KPI RU VI Balongan, who were selected using a purposive sampling technique. The digitalization variable was measured through indicators of digital technology adoption, improvement of employee digital culture and skills. Business process innovation was evaluated based on operational cost reduction, increased process speed, while organizational performance was measured through effectiveness and efficiency indicators. The data analysis technique used was Multiple Linear Regression (MLR). MLR was chosen because of its ability to test the simultaneous and partial influence of several independent variables on one directly measurable dependent variable. The results showed a regression coefficient of 0.975 with a t-value of 19.700 and a significance level of 0.000. This shows that digitalization has a very significant and positive influence on business process innovation. Meanwhile, the results of multiple linear regression analysis show that business process innovation has a regression coefficient of 0.474, with a t value = 7.080 and significance = 0.000. The Beta value of 0.529 indicates that business process innovation makes a significant contribution to improving organizational performance. The influence of digitalization and business process innovation on organizational performance has a fairly strong level of strength because the R2 value is getting bigger (approaching one) and it is known that the influence of digitalization and business process innovation on organizational performance is 0.843 or 84.3% while the remaining 15.7% is influenced by other factors not examined in this study such as leadership and management, organizational culture, human resource competencies and so on. The three variables are interrelated and form a value chain that strengthens the competitiveness and efficiency of PT KPI RU VI Balongan. Ultimately, the contribution of this study is to provide empirical evidence on the role of digitalization in improving organizational performance in the Indonesian oil refinery industry, while providing practical guidance for the management of PT KPI RU VI Balongan.
