Abstract

Al-Ghiff Steak is a restaurant located in Cirebon City that offers quality steaks at affordable prices. For maintaining a competitive Al-Ghiff Steak advantage and reputation, it is important to build a good relationship with customers and have a business strategy that considers customer opinions. However, in its implementation, Al-Ghiff Steak has difficulty when collecting and processing customer review data manually. Therefore, it is necessary to conduct sentiment analysis by utilizing Google Reviews to determine customer perspectives regarding Al-Ghiff Steak products and services. This analysis was conducted on 968 Google Review reviews from 2016 to 2020 using the Support Vector Machine (SVM) and Term Frequency-Inverse Document Frequency (TF-IDF) methods. Classification testing is done with a confusion matrix against four parameters: accuracy, precision, recall, and f1-score. SVM with TF-IDF gets accuracy value 83%, precision 64%, recall 60% and f1-score 59%. The sentiment classification result is then visualized in the form of a dashboard. We utilize the System Usability Scale (SUS) for usability testing, which produces a value of 77.5. This result achieve the Acceptable category and an Excellent rating.

Abstract

Social sustainability is a critical aspect of sustainable development, particularly in the mining industry, which carries high risks related to occupational health and safety. This study aims to design a Health, Safety, and Security (HSS) dashboard to support data-driven decision-making within a mining industry holding group. The development follows a User-Centered Design (UCD) approach and is evaluated using the Dashboard Assessment Usability Model (DATUS). The dashboard was developed iteratively by applying principles of the Visual Information Seeking Mantra (VISM), Gestalt, and Data Storytelling. It comprises 32 HSS indicators grouped into four main modules: KPI, Health, Safety, and Security. Testing results show high effectiveness, with a task completion rate of 98.9%, an error rate of 1.1%, and an 18.04% improvement in task completion time during the second session. User satisfaction scored 88.3 out of 100. These results indicate that the dashboard effectively enhances monitoring and strategic decision-making related to social sustainability in the mining sector.
