Elementary school teachers in Cisauk District who are members of PGRI (Persatuan Guru Republik Indonesia) reported that student learning outcomes during the covid-19 pandemic were no better than before and they realized that students were less motivated. The purpose of this community service activity is to improve the knowledge and ability of teachers in Cisauk District in using Quizizz. This activity was held in virtual training for 46 teachers and school principals. The methods used are discussion, demonstration, assignment, monitoring, mentoring, and evaluation. The teacher is given the task of making a Quizizz and testing it for their students in class. Teachers are also accompanied and guided in completing assignments. From the results of the training, teachers showed an increase in knowledge and skills using Quizizz. Quizizz also has a positive response from students.

Abstract

This study investigated guest satisfaction drivers at Hotel Santika Premiere ICE BSD through a thematic analysis of 1,008 guest reviews. The research addressed the growing need for data-driven insights in the hospitality industry to better understand guests' diverse needs and expectations. Through qualitative analysis, five key themes emerged as pivotal satisfaction drivers: service quality and staff responsiveness (each with 250 mentions, 24.8%), cleanliness (200 mentions, 19.8%), amenities (150 mentions, 14.9%), and value for money (150 mentions, 14.9%). Service quality and staff responsiveness demonstrated the most substantial influence on guest satisfaction, shaping the emotional and relational dimensions of the experience, while cleanliness and amenities established fundamental expectations. Demographic analysis revealed significant variations, with older adults and international travelers reporting higher satisfaction levels (92% and 93% respectively) than younger guests and domestic travelers (85% and 87% respectively). These differences highlighted the importance of demographically tailored services, such as enhanced technology integration for younger guests and culturally adapted offerings for international travelers. Based on the findings, strategic recommendations include improving soundproofing, diversifying breakfast options, and implementing comprehensive staff training programs to address concerns identified in 27% of guest feedback. This research contributes to hospitality management theory and practice by demonstrating the effectiveness of data-driven decision-making in optimizing service delivery while balancing standardized excellence with personalized guest experiences. The study provides a framework for sustainable competitive advantage in the evolving hospitality landscape through strategic alignment of service delivery with diverse guest expectations.

Abstract

This study aims to identify the challenges faced by PT "X" in exporting pharmaceutical products. The research employs a descriptive qualitative approach through in-depth interviews with Export Specialists, Export Customers, and Export-Import Managers. The findings reveal that the main challenges include navigating international regulations, managing logistical complexities, adjusting products to meet buyer preferences, political and economic risks in destination countries, currency fluctuations, competitive pricing, and building robust distribution networks. Regulatory navigation involves adapting documents such as dossiers and stability requirements for Zone IVB. Logistical complexities pertain to shipping goods under specific conditions, such as cold chains, and external obstacles like lockdowns. Product adjustments involve changes in packaging design, the use of local languages, and compliance with shelf-life requirements. Political and economic risks include fluctuations in demand and payment issues from buyers. For pricing, challenges arise from unexpected costs and price comparisons with competitors. Distribution constraints stem from limited control over third-party-managed channels. PT "X" employs various mitigation strategies, including technology-based logistics management, intensive communication with partners, and careful selection of distribution partners. This study provides a concrete overview of the challenges faced by pharmaceutical companies in export activities and strategic measures to enhance competitiveness in international markets.

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

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.
