Abstract

The aim of this research is to determine the effect of service quality and premiums on participant satisfaction at the BPJS (Social Security Administration) Health Office, Sibolga Branch. The effects of service quality and premiums are analysed both partially and simultaneously on participant satisfaction. The research method used is quantitative research. Data collection was carried out using questionnaires distributed directly to BPJS Health participants at the Sibolga Branch through a survey technique. The sample in this study consists of 99 BPJS Health participants from the Sibolga Branch. The analysis methods employed include validity tests, reliability tests, classical assumption tests, multiple linear regression analysis, and hypothesis testing. The results of the study indicate that: (1) the service quality variable has a positive and significant effect on participant satisfaction, with a value of 9.113; (2) the premium variable has a positive and significant effect on participant satisfaction, with a value of 3.629; (3) the service quality and premium variables simultaneously have a positive and significant effect, with a value of 68.931; (4) based on the coefficient of determination (R²), the value is 0.590 or 59%, while the remaining 41% is influenced by other variables not examined in this study, such as location, promotion, and others.

Abstract

This study aims to analyze the influence of safety culture and ship engine maintenance on accident prevention, which in turn affects maritime safety at PT Indo Container Lines. This research uses a quantitative approach with a cross-sectional research design. The sample used in this study consists of 107 crew members of PT Indo Container Lines, selected using the Slovin formula to determine a representative sample size. The data collected includes primary data obtained through questionnaires and interviews, as well as secondary data from the company's reports on safety and ship maintenance. The collected data was analyzed using SmartPLS software to test the relationships between the variables involved. The results of the study show that safety culture has a positive and significant impact on accident prevention, which in turn leads to improved maritime safety. These findings indicate that a strong safety culture, including awareness and safe behavior, plays a key role in reducing the risk of accidents during voyages. Additionally, ship engine maintenance was found to have a positive and significant impact on accident prevention, with well-maintained engines reducing the potential for technical failures that could jeopardize maritime safety. Accident prevention, driven by good engine maintenance and an applied safety culture, contributes to the overall enhancement of maritime safety. This study recommends that PT Indo Container Lines continue to strengthen the safety culture among its crew and enhance ship engine maintenance to support better maritime safety. By creating a safer work environment and ensuring that ships operate in optimal conditions, PT Indo Container Lines can reduce the risk of accidents and significantly improve maritime safety in the future
