In providing this assistance, it is necessary to select prospective recipients. The problem faced by the committee is that the selection is carried out by directly and randomly appointing students so that they have difficulty determining who is actually entitled to receive assistance. To overcome this problem and get candidates who are entitled to receive and achieve the desired standards, it is necessary to apply the eligibility selection of students receiving educational assistance using the Simple Additive Weighting (SAW) method as decision support. The SAW method seeks a weighted addition based on predetermined assessment criteria. The criteria used in this system are; the amount of parents' income, the average value of report cards, the number of relatives / relatives. From the test results of this system, the output is in the form of a ranking of the final values ranging from largest to smallest. The results of the comparative analysis of this system with the old system regarding the level of accuracy are 18 out of 30 students (60%) in the old system, while the new system is 30 out of 30 students (100%). The results of the questionnaire related to the feasibility test of the application for selection of students receiving educational assistance using the SAW Method are very easy to use (Perceived Ease Of Use) with a final value of 86.3%, and very useful (Perceived Of Usefulness) with a final value of 88.3%. The contribution to SMK NU</em><em> Ma’arif</em><em> 2 Kudus in this study was the making of an application to find out the eligibility of student beneficiaries using the SAW method. This can assist the committee in implementing the education aid fund distribution program in an optimal, transparent, on target and equitable manner and can be used as decision support for stakeholders.</em><em></em></p><p><em><strong><br /></strong></em></p>

In this research, the presence of students' attendance at the Taruna Bulu Vocational School has been observed where the system used is still manual so it requires a computerized system so that archiving is efficient and the homeroom teacher and student guardian can control student attendance.In conducting research, the author uses two sources of data, namely primary data which includes all data obtained by the author directly from sources obtained from the Head of Vocational School Hair Training and secondary data which includes all information obtained from other data that can be used as a support and related to the research theme. These data sources are documents concerning the student attendance information system procedures. In designing the system, it is made based on the needs of SMK Taruna Bulu which is then implemented using the PHP My SQL programming language and integrated Telegram Bot so that it can later be implemented on Taruna Bulu Vocational School.
Evaluation of information system performance is needed to get an overview of the ease of end-users in utilizing a new technology. This study aims to evaluate the performance of information systems in a state-owned company (PT PLN Madya Langsa) based on an end-user perspective that is separated into two categories: employees and managers. The level of employee satisfaction (primary user) is measured using EUCS (aspect of: content, accuracy, format, ease of use, timeliness, and satisfaction). The manager's satisfaction level (secondary user) is measured by using IT BSC (aspect of: company contribution, user, operational excellence, and future orientation). The evaluation on the primary user showed that it was low at 25.6%, moderate at 56.64% and high at 18%. The percentage of user satisfaction with the information systems is 72.9% of the results expected by users. Meanwhile, evaluation on the secondary user obtained the following results: low at 10.5%, moderate 84.2% and high at 5.3%. The percentage of user satisfaction with the information system was 92.8% of the results that is expected by users. This study also discusses why there are differences in the percentage of primary user satisfaction compare to the secondary user and provides suggestions how to improve the level of satisfaction of the end users in the future.
The increase in internet users in Indonesia is in line with the growth in the number of domain users. This has implications for the number of local servers used, including in the education sector. Utilization of this local server has become something that has been started by several educational institutions in Indonesia. However, just implementing a local server at each institution is not enough. Measurements need to be taken to get an idea of whether the technology implementation is classified as successful or not. The approach method that can be used is Delone Mclean which has indicators to measure success. In this study, data was taken from high schools that had implemented local servers. The data used is in 10 high schools, where each school will send 3 respondents to fill out the application of the local server at their institution with a total of 30 respondents in this study.
