One of the benefits of the development of information systems is to increase effectiveness, efficiency and convenience in various aspects of technological life, especially in the scope of education, such as at SMK Negeri 1 Banyumas which implements a library visit system. But there are also challenges in its implementation, such as theft of personal data and misuse of data by irresponsible people. By conducting an information system audit, we can better understand the weaknesses of the system, for example, using COBIT 5 to view and evaluate the information system. as in the questionnaire that we distributed shows that there are 79% of students feel safe about the library visit system and 4.8% of students feel that the library visit system is not secure enough for almost the same reasons such as the authentication system that only relies on a username in the form of NIS and no password. From this data we can provide recommendations such as implementing a password system and 2-factor authentication in order to better protect personal data, files, systems, networks, and so on so that the system becomes better and more secure.

The “AntriSmecone” queuing system was implemented in the PPDB process at SMK Negeri 1 Purwokerto to improve efficiency by up to 70%. However, the system encountered several issues, such as race condition conflicts in queue numbers and code execution errors caused by automatic translation. This study employs the IT-IL V3 framework, focusing on the Service Operation domain to analyze IT service management, particularly in the subdomains of incident management and request fulfillment. The research methodology includes interviews, observations, questionnaire distribution, and literature studies. The analysis results indicate that the system's maturity level is at level 4 (Managed and Measurable), with an average score of 3.74. The system has structured and monitored procedures, allowing deviations to be effectively addressed. Recommendations were formulated to optimize incident management and fulfill user requests. This study contributes to the development of the “AntriSmecone” system to ensure service quality and efficiency in the PPDB process.

Bicycles are affordable and healthy, cause zero harm to the environment, require little space on roads and parks, and are not noisy transportation means. However, cyclists face challenges on roads, which may lead to injuries and deaths. For instance, cyclists visibility, speed management, ability to communicate with other road users, backward accidents, and ability to be located in urgent cases. This paper presents performance, tracking, and safety systems from hardware and software point of view. As a result, cyclists monitor their speed to manage; their locations are tracked, and their cycling paths are traced. Also, a rear red light and turn signal LEDs are activated without any physical action from the rider to communicate with other drivers. Moreover, a microwave radar sensor with a range of seven meters is employed to protect the cyclist from backward-approaching vehicles. Finally, three Arduino UNO boards with GPS, GSM modules, MPU-6050, and RCWL-0516 sensors are mounted on a conventional bicycle to provide safer trips.

The library management information system for SMP Negeri 2 Solear has been successfully implemented. Purpose of creating this information system is to make it easier for members to see the list of available books and borrow books easily, namely online, and to help admin staff in managing book, member and book borrowing data. This information system has two views, namely the user page and the admin page. On the user page, users can register as library members, see available books, and can borrow the books they want. On the admin page, the admin can add, subtract and manage book data, view members' borrowing history, and can see the number of books available. This application was created using PHP and MySQL programming languages, the writing method used was System Development Life Cycle (SDLC), system design used Unified Modeling Language (UML), and system display design used Dia Diagram. It is hoped that with this information system users and admins can access the system anywhere and anytime via the internet. And users don't need to come to the library just to see the availability of the books they want to borrow. Apart from that, admin work can be lighter without taking notes manually.

The fluctuation of fuel prices (BBM) significantly impacts the national economy and public purchasing power. This study examines the dynamic relationship between fuel price adjustments, economic growth, inflation, and the socioeconomic conditions of society. The findings reveal that an increase in fuel prices often triggers a domino effect, including rising transportation and production costs, ultimately affecting consumer prices and reducing purchasing power. Conversely, the decline in fuel prices provides a short-term boost to public spending but may challenge government revenue if fuel subsidies increase. Policy recommendations include balancing fuel price adjustments with measures to protect vulnerable groups and maintain economic stability.
