Abstract

In contemporary times, the use of smartphones has become an essential requirement for daily life in the digital era. The prevalent consequences of smartphone usage include the development of poor posture and behaviors. This study aimed to assess the risk of musculoskeletal disorders (MSD) among smartphone users, focusing on adolescents aged 12 to 19 years. A sample of 82 students (79.3% female and 20.7% male, with an average age of 15.7 ± 2 years and a normal BMI of 76.8%) in the West Lombok district of the West Nusa Tenggara Province in Indonesia was measured. Data collection through simple random sampling involved distributing questionnaires to participants and requesting them to provide responses based on their personal experiences. The present study employs a chi-square analysis to examine the association between smartphone usage, posture behavior, and the highest values of MSD complaints. The findings indicate that the neck (46.3%) and back (45.1%) were the body regions with the most prevalent complaints of MSD. The participants frequently engaged in standing without support and walking as their posture behaviors. There was a significant correlation between the level of neck pain and posture during walking. The use of smartphones among adolescents has an impact on the risk level of experiencing MSD complaints, thereby increasing the potential for illness and abnormalities. Hence, it is necessary to exercise sufficient control over the routine usage of smartphones to mitigate the negative impacts incurred.

Abstract

Background: Motorcycle repair shops in developing economies often operate with inadequate safety standards, exposing workers to health and safety hazards. This study aimed to investigate the relationship between unsafe work practices and work-related stress among motorcycle mechanics in Lombok, Indonesia. Methods: A cross-sectional study design was employed, with data collected using self-administered questionnaires from a sample of 148 male motorcycle repair workers. Descriptive statistics, validity and reliability testing, and Chi-Square tests, used to analyze the data. Results: The study found a significant association between working while visibly sick (presenteeism) and elevated stress levels. Additionally, working while visibly fatigued was also associated with increased stress. Discussion: These findings highlight the detrimental impact of presenteeism and fatigue on worker well-being within the motorcycle repair industry.  The lack of association with other unsafe practices suggests that additional workplace stressors may be influential in this setting. Conclusions: Employers in the motorcycle repair industry should prioritize policies that discourage working while sick and promote adequate rest to mitigate stress and potential safety risks. Further research, including qualitative methods and diverse samples,  is needed to fully understand the complex interplay between unsafe practices, stress, and other workplace factors affecting worker well-being.

Abstract

Marine tourism destinations commonly rely on tourist boats as the primary means of transportation to visit surrounding attractions. Improving the competitiveness of small and medium-sized enterprises (SMEs) in the tourism industry can be largely achieved through the development of boats that prioritize usability. The tourism ecosystem depends heavily on transportation, particularly marine vessels, which are central to the operation of marine tourism destinations. A usability-focused analysis of tourism boat design can significantly enhance the competitiveness of SMEs operating in this sector. However, empirical studies applying standardized usability evaluation tools to SME-operated marine tourism vessels in developing countries remain limited. This study aims to evaluate the usability of a tourism boat using a structured usability assessment approach. Respondents were recruited through purposive sampling and assessed using an adapted System Usability Scale (SUS) instrument based on a five-point Likert scale. The SUS questionnaire was administered to evaluate the perceived usability of the tourism boat. A tourist boat with a SUS score of 52.2 falls within the marginal-low range. This indicates that while the boat's usability is rated in the lower range, it remains within an acceptable threshold. Key usability issues identified include absent seat handrails, difficult-to-open windows, narrow staircases, and insufficient life jackets. Accordingly, the proposed improvements focus on redesigning the boat to be more user-friendly, emphasizing ease of use and operational effectiveness as core usability principles. These findings provide practical guidance for SME operators and policymakers in adopting user-centered vessel design to enhance service quality and regional marine tourism competitiveness.
