Abstract

Improving the quality of life for deaf students with special needs, the development of assistive technology is crucial to aid in the classroom learning process. This research aims to design an assistive technology in the form of a Smartband that is beneficial for helping deaf students to interact, understand instructions, and engage in social interactions. The design of this smartband employs the Quality Function Deployment method to ensure that the needs and desires of deaf students are met in the designed device. Based on the analysis of questionnaires from 43 deaf students, eight Customer Requirements were identified. The top priorities for development were voice call detection (14.2%), surrounding hazard alerts (13.99%), and notification capabilities (13.49%). By utilizing the Relationship Matrix in the House of Quality, the Technical Priorities to be developed were determined, namely a voice recognition sensor (19% with a technical importance score of 135), followed by ESP32 and Vibration Motor (16% with a technical importance score of 117). The designed smart bracelet functions well but requires further evaluation, especially in terms of aesthetics, as the current respondents were limited and did not differentiate based on age, which is known to have varying preferences.

Abstract

Occupational safety is a crucial factor in maintaining operational continuity and employee well-being, particularly within the high-risk oil and gas industry. This study aims to evaluate the safety climate at PT Pertamina (Persero) Integrated Terminal Bitung using the Nordic Occupational Safety Climate Questionnaire (NOSACQ-50) instrument. A quantitative research approach with a survey design was employed, involving 79 respondents. Data were analyzed using the Mann–Whitney and Kruskal–Wallis tests to assess differences in perception among groups based on education level and length of employment. The results indicate that five out of seven safety climate dimensions fall within the “good” category, namely management commitment and competence in safety (3.49), management justice (3.32), worker commitment (3.25), learning, communication, and trust (3.34), and trust in the effectiveness of the safety system (3.33). The remaining two dimensions are categorized as “fair,” which include management safety empowerment (2.94) and safety priority and non-tolerance of risk (2.73).
