Abstract

In the digital era, technology has transformed the travel and tourism industry, with Online Travel Agents (OTAs) like Traveloka, Tiket.com, and Agoda offering convenient trip planning through digital platforms. Despite their popularity, issues such as navigation difficulties and unclear information still affect user satisfaction. This study aims to evaluate the usability of OTA applications using the System Usability Scale (SUS) based on the ISO 9241-11 standard and Electroencephalography (EEG) to analyze user physiological responses. The test involved 10 respondents and 4 task scenarios. The results showed that Traveloka achieved a SUS score of 85, with 95% effectiveness and 0.023 goals per second efficiency. Tiket.com scored 79 with 92.5% effectiveness and 0.026 goals per second efficiency, while Agoda scored 70 with 87.5% effectiveness and 0.016 goals per second efficiency. EEG data revealed that Traveloka and Tiket.com had the highest average alpha wave values, indicating respondents felt nervous or anxious, whereas Agoda showed higher beta wave values, suggesting respondents were calm and aware without full concentration. This study highlights that the usability of OTA applications is influenced by user experience, which can be measured subjectively through SUS and more deeply using EEG data to understand physiological responses when interacting with the application.

Abstract

Human error is a significant contributor to workplace accidents in the manufacturing industry, particularly in the sugar production sector at PT XYZ, where specific challenges such as operator inexperience and equipment mismanagement heighten these risks. This study addresses a critical research gap by analyzing human error factors in the sugar production process using the HEART (Human Error Assessment and Reduction Technique) and Fuzzy FMEA (Failure Modes and Effects Analysis) methodologies. The HEART method quantitatively identifies human error probabilities at various production stages, while Fuzzy FMEA evaluates risk levels and prioritizes accident mitigation strategies. Key high-risk activities identified include improper use of the core sampler (HEP: 0.038, Fuzzy RPN: 500), data entry errors (HEP: 0.234, Fuzzy RPN: 120), and misoperation of the centrifugal machine (HEP: 0.304). The lowest risk was associated with slipping due to juice spills (Fuzzy RPN: 332). This innovative integration of HEART and Fuzzy FMEA offers a novel approach to developing effective mitigation strategies, including enhanced operator training, the establishment of standard hygienic sampling procedures, safety morning talks to raise awareness of safety, software training for operators, health checks before starting work, regular review and approval of data, weekly data audits, and the implementation of warning letters for frequent mistakes. By improving these safety systems, this research aims to significantly reduce accident risks and increase operational efficiency in the sugar industry.
