In the ever-changing digital world, strong security protocols are essential. As a vital line of defence against unwanted access, blockchain uses several verification techniques to boost security. This article investigates the use of blockchain technology to tackle privacy, security, and usability issues. By reducing the dangers associated with conventional centralised systems, blockchain's decentralised and immutable structure offers a secure platform for storing and verifying authentication credentials. This method increases user trust by using smart contracts to guarantee transparent and unchangeable authentication procedures. The suggested blockchain-based method strengthens security and enhances privacy by removing sources of failure and decreasing dependence on outside verification. Furthermore, user-centric design and expedited procedures improve the system's usability by making secure authentication more approachable and less obtrusive. This paper offers a thorough examination of the suggested system, stressing its benefits, possible drawbacks, and directions for future investigation. The results indicate that blockchain technology presents a viable solution to ensure that digital authentication frameworks combine privacy, security, and usability.

This research was carried out with the aim of explaining the implementation of a mobile-based legal metrology service system for employees and improving the quality of services for legal metrology at the Jombang Regency Office of Trade and Industry. With this mobile-based legal metrology service application, it can make it easy for employees to see the calibration and re-calibration schedule sent by the central metrology website and employees can send the results of the test and re-calibration directly in real-time without having to come to the metrology office. This research applies the waterfall method in its development, which is a systematic and structured approach involving a series of sequential stages. The results of this research created a mobile-based application for employees of the Jombang Regency Trade and Industry Office.
 
 

This research aims to analyze time and cost control on the ITC Pole Fiber Optic project managed by PT. LUM uses the Earned Value Management (EVM) method. EVM is an effective method for measuring project performance and progress by combining cost, time and completed work data. This case study uses secondary data obtained from project progress reports and PT financial data. LUM. Analysis is carried out to identify cost variance (CV) and schedule variance (SV) as well as cost performance index (CPI) and schedule performance index (Schedule Performance Index - SPI). The research results show that the ITC Pole Fiber Optic project experienced several deviations from the planned budget and schedule, with CV and SV showing negative values ??at several project stages, indicating cost overruns and delays. The CPI and SPI values ??obtained also provide an overview of the efficiency and effectiveness of project implementation. Based on these findings, several improvement steps are recommended to optimize time and cost control to improve project performance in the future. This research makes an important contribution in providing insight into the application of EVM in fiber optic installation projects and can be used as a reference in managing similar projects in the future.

This study explores the effectiveness of STEM education in developing spatial thinking skills in elementary school students. The study employs a quasi-experimental design involving two groups: an experimental group that received STEM intervention and a control group following the standard curriculum. The results indicate that the experimental group experienced significant improvements in visualization, spatial relationship understanding, and spatial object manipulation compared to the control group. These improvements are primarily to technology, such as 3D simulations and design software, which help students comprehend complex spatial concepts. Further statistical analysis supports these findings, showing significant differences between the experimental and control groups. These findings underscore the importance of integrating STEM education into the curriculum to enhance students' spatial skills, which are critical in various science and technology disciplines. However, challenges in implementation, such as a need for more resources and teacher training, must be addressed to ensure the program's effectiveness across different educational contexts.
