Abstract

Kantin Hijrah at FT Untirta is among the food and beverage businesses located at the Faculty of Engineering, Sultan Ageng Tirtayasa University. Continuous efforts are essential to enhance service quality to achieve satisfied and loyal customers. This study aims to assess the service quality at Kantin Hijrah FT Untirta and suggest improvements by utilizing the SERVPERF, PGCV, and TRIZ methods. Questionnaires were distributed to 97 active FT Untirta students for data collection. According to the SERVPERV method, the service quality yielded a score of 3.64, indicating satisfaction. Additionally, utilizing the PGCV and TRIZ methods identified five attributes for improvement: maintaining cleanliness in the restroom, ensuring a well-kept handwashing area, providing menu books, adequate and well-maintained tables, and chairs, and ensuring the overall comfort of Kantin Hijrah (i.e., maintaining a suitable temperature and reducing noise). Implementing these proposed improvements aims to further enhance the service quality at Kantin Hijrah.

Abstract

The use of e-wallets in Indonesia has been developing since their emergence in 2011. The circulation of electronic money has been increasing, particularly in urban areas, due to the rising digital literacy of people. However, there was a significant increase during the Covid period when restrictions were imposed on community activities to prevent the spread of the virus. During this period, the circulation of electronic money more than doubled from the previous year. The perception of e-wallet users is crucial as it provides valuable information about their expectations and preferences. This information helps e-wallet providers determine whether their products or services meet the users' expectations. The e-SERVQUAL method is used to measure e-wallet user perceptions, which evaluates the quality of electronic services provided by companies through electronic media. Therefore, this study aims to investigate whether there is a significant difference in e-wallet user perceptions using e-SERVQUAL before and after the Covid period. The survey method was used in this study. The results showed a significant difference between users' perceptions before and after the Covid period with a significance value below 0.05.

Abstract

Supply chain risk management plays a pivotal role for businesses, regardless of their size—be it large industries or Micro, Small, and Medium Enterprises (MSMEs). Even in MSMEs, supply chain risk management is crucial to mitigate potential risks stemming from various events. Consider BS, an MSME producing bread in Cilegon city, established in 2020, aspiring for market expansion. However, BS faces internal challenges such as fluctuating flour availability, recurring machine breakdowns twice a month, and consumer returns due to order discrepancies. Thus, this study aims to analyze supply chain risks to proactively prevent these recurrent events. The method employed here is the House of Risk. Through data processing, 32 risk events were identified by mapping supply chain activities based on the SCOR principle. From these events, 18 risk agents were derived, highlighting critical areas that require resolution. Employing a Pareto diagram, six priority risk agents have been identified for immediate resolution.

Abstract

Lean Healthcare is an approach to management systems that can change the mindset of hospitals, making healthcare more organized by reducing waste. Waste can be defined as any activity that does not add value to a process. The study recommends a bibliometric analysis of this problem. This is necessary to identify research trends or gaps that still exist. Data searches use Publish or Perish software, while data analysis uses VOSviewer software. The search results and data analysis suggest that trends for Lean Healthcare problems will likely be resolved by integration with green practices. The final process can be carried out considering environmental sustainability factors.

Abstract

A furniture manufacturer, a Small and Medium Enterprise (SME) whose main product is wooden chairs, has experienced problems in its manufacturing process. There are products that do not meet the desired size. The purpose of this research is to identify the most dominant waste through Borda weight calculations, determine the tools used in Value Stream Analysis Tools (VALSAT), find the root causes of the problems, and provide improvement suggestions using a fishbone diagram, as well as prioritize improvement suggestions using the Analytic Hierarchy Process (AHP). The research results using Borda weighting found that the most dominant waste was defect waste with a weight of 0.29. The VALSAT tool selected was Process Activity Mapping (PAM) with a score of 5.94. Improvement suggestions based on the fishbone diagram include work supervision, scheduling equipment and machinery maintenance, raw material checks, the creation of standard operating procedures (SOPs), and human resources training. The improvement suggestion prioritized based on the AHP results was the creation of standard operating procedures (SOPs) with a weight of 0.500. The difference in Process Cycle Efficiency increased from the previous 71% to 76% after the improvements.

Abstract

Zoom accounts are used as an alternative for online teaching and learning activities during the pandemic. The Industrial Engineering Study Program at Sultan Ageng Tirtayasa has been scheduling online exams and determining the number of Zoom accounts needed manually, which has resulted in an insufficient number of Zoom accounts to meet all course schedules. Proper online exam scheduling can optimize the number of Zoom accounts required. This study aims to determine the number of Zoom accounts needed for online exams by developing a mathematical model. The model developed is an Integer Linear Programming (ILP) model, with the objective of minimizing the number of Zoom accounts required. The problem is solved using an optimization approach with deterministic parameters. The model provides recommendations for decision-making in the implementation of online exams, including determining the exam timetable and the number of Zoom accounts to be rented. The computational results show that the developed model provides an optimal solution, requiring only three Zoom accounts.
