Abstract

Indonesia is a country located in the Pacific Ring of Fire, because of this Indonesia is vulnerable to earthquakes because it is located at the meeting point of several colliding tectonic plates. In addition, the presence of active volcanoes is also an additional factor. The construction of high-rise buildings in Indonesia has continued to increase in recent years along with the growth of urbanization and the need for more efficient space in urban areas, this has increased the risk of accidents in high-rise buildings. With these problems, a disaster simulation is needed which can be the right step to understand the correct ways to handle and evacuate from disasters. The right simulation for this problem is to use Virtual Reality (VR)-based learning because this simulation can increase the effectiveness of disaster management education by experiencing firsthand a realistic and interactive earthquake scenario simulation. The results of the pre-post test processed using the Wilcoxon signed rank test method obtained a result of 7.5 where 7.5 ≤ 52 (critical value) concluded that this simulation provides a significant change in knowledge of earthquake disaster mitigation in high-rise buildings. And from the SUS (System Usability Scale) Questionnaire, the score obtained was 78.875 which is included in the category 70-85 which means that this system is quite good in terms of usability. Users generally feel comfortable using the system.

Abstract

The application of digital technology in the worker health screening process is an important need in the industrial work environment, especially in supporting the effectiveness and efficiency of the OHS medical team's work. This research aims to design a user interface for the AppSheet-based worker health screening application using the Design Thinking approach. This method was chosen because it is centered on user needs and is able to produce innovative solutions through the stages of Empathize, Define, Ideate, Prototype, and Testing. Data collection was conducted through interviews and observations of five respondents from the OHS medical team and five department representatives. Assessment of the design was carried out using the usability testing method, with efficiency, effectiveness, and System Usability Scale (SUS) parameters. The results showed that the Design Thinking approach was able to produce an application interface that meets user needs, improves understanding of workflows, and minimizes recording errors. The developed application not only supports the digital health evaluation process, but also has the potential to reduce administrative burden and improve the quality of medical services at PT Petrokimia Gresik.

Abstract

Industrial Revolution 4.0 increases the demand for batteries but also increases the risk of workplace accidents in factories such as PT TMB. Production processes involving chemicals and heavy equipment cause potential hazards. In the last three years, accidents have increased, disrupting production and adding costs. Therefore, this research aims to identify risks and provide risk mitigation in the battery production process. This research uses Fuzzy Fault Tree Analysis (FFTA) to identify hazards and reduce risks, in order to improve the safety and competitiveness of the company. This research was conducted at PT TMB by combining qualitative analysis to understand general conditions and quantitative to analyze the risk of workplace accidents, such as fire, fatigue, operator injury, and worker health. The Fuzzy Fault Tree Analysis (FFTA) method was used to map and reduce potential hazards, as well as develop more effective work safety policies. The results of the research explained that there are four top events with different probabilities and impacts: fire risk (A) 26.82%, occupational fatigue (B) 11.57%, occupational injury (C) 40.58%, and occupational health (D) 21.03%. From the four top events mentioned above, mitigation is focused on the 3 highest positions based on the assessment of the matrix table, which are fire risk, occupational injury, and occupational health.

Abstract

This study aims to evaluate the usability level of the Virtual Reality (VR) simulation system for earthquake preparedness training at the Environmental Agency of East Java Province using the System Usability Scale (SUS) method. The testing was conducted with nine respondents who performed two task scenarios in the simulation and subsequently completed the SUS questionnaire. The analysis covered three main aspects of usability: effectiveness, efficiency, and user satisfaction. The results showed an effectiveness level of 100% (“Highly Effective” category), an average efficiency of 0.01758 goals/second (“Very Fast” category), and an average SUS score of 73.88, which falls into the “Acceptable” category with an adjective rating of “Good.” These findings demonstrate that the VR simulation has strategic potential as an effective and efficient interactive training medium for improving the understanding of earthquake evacuation procedures. Nevertheless, improvements are needed in interface consistency and in reducing the initial learning curve to optimize the user experience.
