<![CDATA[Tahfizh, the memorization of the Qur’an, requires persistence, accurate recitation, and comprehension. In institutions such as STP Khoiru Ummah, assessing students to determine the best tahfizh is often challenging because the manual process is time-consuming and prone to bias. To address this, a Decision Support System (DSS) was developed to support the selection process. The system applies the Simple Additive Weighting (SAW) method, which is suitable for multi-criteria decision-making. Criteria such as memorization quality, tajwid accuracy, fluency, and behavior are considered in the assessment. The development adopts the Rapid Application Development (RAD) model to ensure efficiency and adaptability based on user requirements. This research is expected to produce a system that enhances accuracy, transparency, and efficiency in selecting the best tahfizh, thereby contributing to the improvement of Qur’an memorization education at STP Khoiru Ummah Serpong.]]>

<![CDATA[The management and monitoring of service contract status in the Service Procurement Department of PT. Pupuk Sriwidjaja Palembang (PT Pusri) currently rely on manual methods using Microsoft Excel. This manual system has numerous limitations that lead to problems, such as difficulty in tracking contract status (active, nearing expiration, or expired), delays in identifying contracts about to expire, and the potential for data input errors. These limitations are compounded by the lack of fast and accurate monitoring reports, which hinders the managerial decision-making process. This research aims to design an information system for monitoring service contract status that can help employees of the Service Procurement Department monitor contract status in a more structured, accurate, and efficient manner. The research method used is applied research with an information system development approach utilizing the Waterfall method. The Waterfall method was chosen because it provides a systematic and structured workflow. The stages of this research include Requirements Analysis, conducted through interviews and direct observation of business processes; System Design, which covers the design of the user interface and database; Implementation, in the form of creating a web-based system prototype; and Testing. The result of this research is a monitoring information system design that is expected to facilitate real-time contract monitoring, clearly display contract status, and generate reports that support corporate decision-making. ]]>

<![CDATA[This study aims to design and implement a high-voltage control system for a prototype-scale medical X-Ray device using the Pulse Width Modulation (PWM) method, controlled via an Arduino microcontroller and a Java-based user interface. The system is developed to allow dynamic adjustment of PWM duty cycle, with output voltage responding proportionally to changes in PWM values. Experimental results show a nearly linear relationship between PWM and voltage, indicating that PWM is a stable and effective method for voltage regulation. Additionally, the developed Java interface enables users to set PWM values, exposure duration, and monitor system status in real-time without direct hardware interaction, enhancing operational safety and usability. The system is equipped with an automatic protection mechanism based on voltage feedback from the ADC; the microcontroller will automatically stop the exposure process if the voltage exceeds a predefined threshold. This feature has proven effective in preventing damage due to overvoltage. Overall, the system meets the primary research objective—creating a measurable, safe, and externally integrated high-voltage control mechanism. This research contributes to the advancement of more efficient and adaptable X-Ray control technologies suitable for medical and laboratory applications.]]>

<![CDATA[The selection of the right soccer players is very important to determine the optimal strategy and match results. However, the selection process, which is still carried out manually, often causes mismatches between the players’ abilities and the standards expected by the coach. To overcome this problem, a system is needed that can provide player recommendations objectively and efficiently. This study aims to develop a decision support system for selecting the best players at the Pelita Jaya Sawangan Academy using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. This method was chosen because it can handle multi-criteria decision-making systematically and logically. The system was developed to assess player performance based on several criteria such as goals, assists, yellow cards, red cards, saves, and penalty saves. The final result of this study is a ranking of players based on the highest preference value, which helps coaches determine the best players objectively, accurately, and based on data.]]>
