Digital transformation has led companies to adopt digital attendance systems to improve administrative efficiency. PT. Abdai Indonesia has implemented a web-based attendance system, but several issues have emerged, including a non-intuitive interface, confusing navigation, and features that do not meet user needs. This study aims to analyze and evaluate the system’s usability using the Web Usability testing method. A descriptive quantitative approach was used, with data collected through the System Usability Scale (SUS) questionnaire, direct observation, and structured interviews. The sample consisted of 21 active users from various divisions. The findings show an average usability score of 2.23 out of 5, indicating a low level of system usability. Most respondents expressed dissatisfaction and difficulty using the system, particularly in terms of interface design, navigation, and operational efficiency. Evaluation based on Jakob Nielsen’s five usability components—Learnability, Efficiency, Memorability, Error Handling, and Satisfaction—revealed that none achieved a satisfactory score. These results suggest that the system requires significant improvements, especially in user interface design and overall user experience. This research is expected to serve as a reference for enhancing the digital attendance system in the future, making it easier to use and better aligned with user expectations.

In the current development of concrete innovation technology, there are also expensive materials that are cheap as concrete additives for the efficiency of the cost of making concrete. cheap and can be used as concrete innovation. The purpose of adding palm fiber fiber is to improve the quality of concrete, both compressive strength and split tensile strength. The method used in this study was experimentation by adding palm fiber to the SCC concrete mixture with variations of 2%, 4% and 6%. As for the addition of chemical substances, the superplasticizer admixture aims to make it easier for SCC concrete to achieve a slump flow value that meets the requirements. After testing, the highest compressive strength test specimen is BC 1 2% palm fiber worth 19.38 MPa and for the lowest compressive strength test is BC 2 6% palm fiber worth 5.46 MPa. And for the split tensile strength test the highest is BC 4 2% palm fiber worth 9.47 MPa and for the lowest split tensile strength test is BC 3 6% palm fiber worth 5.82 MPa.
