Agility and speed are two important factors that determine the performance of athletes in various sports. Currently, agility and speed measurements still rely on the use of a stopwatch and human response speed. Although this method has been used in various sports settings for many years. There are several underlying problems, including low levels of accuracy and consistency, the potential for trainer or assessor fatigue, timeconsuming data processing, and the need for proper agility measurement tools. By considering the problems from this background, this study aims to present the development of a touchless sensor-based agility and speed measurement tool that can help improve accuracy, consistency, and efficiency in measuring athlete agility and speed, namely “The Alacrity”. With this tool, athletes are expected to be able to plan appropriate training programs to improve their performance and process data manually because the results are presented in a special Windows application and can be viewed in real-time.

The Covid-19 pandemic, which causes social distancing, has an impact on a surge of buying and selling through mobile commerce. On the other hand, customers are at the risk of online service failure in m-commerce. This research tested the quality model of m-commerce service that integrates the justice variable from the Islamic perspective on Muslim women's loyalty and word of mouth with satisfaction as the mediating variable and personal innovation and customer expertise as the moderating variables. This research is survey research involving 323 Muslim women who use the C2C m-commerce platform services in Indonesia. Data analysis is presented in Structural Equation Modeling. The result shows that distributive justice, procedural justice, visual appeal, ease of use, and security influenced satisfaction, while information quality, load speed, and interactional justice did not affect satisfaction. This research proves that the principle of justice in buying and selling process for Muslim women exists in the m-commerce service so that it plays a positive role in satisfaction which has an impact on the loyalty and word of mouth of Muslim women. This research contributes to providing theoretical background as a service standard for m-commerce platforms that are user-friendly for Muslim women.

This study aims to analyze shopping behaviour and changes in shopping behaviour during a pandemic. Consumers prefer to choose online shopping in pandemic situations according to safety. Data were collected by interviewing 12 respondents from the generation of baby boomers, X, Y, and Z. The data were processed using a qualitative approach using N-Vivo software. Research results showed that there were differences in food shopping behaviour during the pandemic. This research suggests that the food industry pays attention to shopping behaviour change during a pandemic to change strategies to get opportunities in the market.
