Circular economy (CE) is an interesting approach by many countries to address global environmental problems while gaining economic benefits. The implementation of CE is expected to minimize the use of resources and materials, thus contributing to sustainable development. Much literature has discussed CE assessment indicators and their evaluation, however to date, no single indicator has been proposed that can comprehensively measure the macro level of CE implementation. This study aims to develop a CE index to measure CE implementation at macro levels. In addition, it provides an overview of the impact of CE implementation on the financial, social, and environmental aspects of the economy. To this end, first, an in-depth literature review and descriptive analysis is conducted to identify existing global CE indicators and classify them into financial, social, and environmental categories based on available primary and secondary data. Then, the CE index is constructed using a mathematical equation by considering the CE framework, a single indicator of each aspect as a variable, and the variable’s weighting. Finally, the CE index is applied to evaluate the level of CE implementation of CE in Indonesia at macro level. This index is expected to be a valuable tool for measuring CE implementation and therefore improving CE performance.

Improved Human Resources Performance can be realized in the employee’s absence. The sophistication of technology to accommodate the absence is the use of a Mobile-Based Attendance Application. Attendance can be used to measure employee performance. One of the measuring tools in measuring performance is the Key Performance Indicator (KPI). KPI values can be obtained from the Mobile-based Attendance Application, as currently implemented by an IT Company. But in its development, there is a shortage on the application features of Daily Attendance, Leave, Report Recaps Attendance and Report Recaps Leave. The value engineering method with the Analytical Hierarchy Process is used in this paper to obtain prioritized alternatives in the development of application feature updates. The results of the research show that the alternative with the largest percentage is owned by Alternative IV (45.6%). These results indicate that this alternative can be used as a recommendation for renewal of attendance application features on IT Company. Alternative IV shows optimal results such as the realization of application feature requirements for users, consumption of fewer workdays for 1-2 days, low costs, easy-to-understand feature design, and uncomplicated programming techniques.
