Jurnal Ilmu Komputer dan Sistem Informasi (JIKSI) is a peer-reviewed journal devoted to publishing multidisciplinary issues in computer science, information systems, and technology innovation both in Indonesia and around the world. JIKSI is a triannual, open access, peer-reviewed, and international e-journal, published in Indonesia. We accept unpublished, high quality, and original research manuscripts in English, resulting primarily from quantitative, qualitative, and mixed research methodologies related to or associated with computer science, information systems, and technology applications. JIKSI is published three times per year by the Institute of Information Technology and Social Science (IITSS). All research articles appearing in JIKSI have undergone a thoroughly blind peer-review.

Abstract

This study aims to improve the effectiveness of thesis examination assessment management, which includes proposal examinations and comprehensive examinations, through the development of a mobile-based assessment application. The primary issue motivating this research is the irregularity of examination administration, particularly during online examinations implemented during the COVID-19 pandemic. This condition created the need for a system capable of ensuring accurate dissemination of examination schedules, accelerating the assessment process, and organizing examination data recording in a structured manner. The application was developed on the Android platform because this technology is predominantly used by students and lecturers at Universitas Bina Darma. The system development process employed the Mobile-D method, which consists of five stages: Explore, Initialize, Productionize, Stabilize, and System Test and Fix. However, this research was limited to the first four stages, up to the Stabilize stage. The development process involved designing the system architecture and modeling, verifying user requirements and converting them into user interface designs, implementing the application in accordance with user needs, integrating application components, and conducting functional testing. The final outcome of this research is a thesis examination assessment application that supports a faster, more structured, and more efficient academic evaluation process.

Abstract

Papuan students in South Sumatra face challenges related to fragmented communication, limited information accessibility, and low participation in organizational activities. The absence of an integrated digital platform has reduced coordination efficiency within the Papuan Student Community of Sriwijaya (KOMPAS). This study aims to design and empirically evaluate an Agile-based integrated web information system incorporating digital governance and marketplace features to enhance organizational performance and engagement. The system was developed using the Agile methodology through five iterative sprints over a ten-month period involving 15 organizational stakeholders and 75 active members. The platform was implemented using Laravel and MySQL within a three-tier architecture framework. Evaluation procedures included functional testing, performance analysis, and usability assessment using the System Usability Scale (SUS). The results indicated an average page load time of 1.2 seconds (desktop) and 2.8 seconds (mobile), with a PageSpeed score of 94 and 85% unit test coverage. The system achieved a SUS score of 82.5, categorized as excellent usability. After one month of implementation, information accessibility increased from 24% to 76%, participation rose from 38% to 62%, and member engagement improved from 31% to 73%. The marketplace module recorded 23 transactions totaling Rp 8,500,000. These findings demonstrate that integrating digital governance mechanisms with marketplace functionality significantly enhances coordination, engagement, and economic participation in student-based community organizations.

Abstract

This research designs and implements a water tank control and monitoring system based on a Programmable Logic Controller (PLC) integrated with a Human-Machine Interface (HMI) to enhance operational efficiency and reliability in an industrial environment. The system is built using a Schneider M221 PLC and analogue modules, with a level transmitter as the primary sensor for level control, and flow and temperature transmitters to complement process condition information. The control logic is implemented using ladder logic in EcoStruxure Machine Expert. At the same time, the HMI interface is developed in Vijeo Designer for real-time visualization, setpoint adjustment, and pump status monitoring and alarms. System performance is evaluated through hardware functional testing (power supply, relay, pump) and sensor testing based on 4–20 mA signals converted using a scaling Equation. To further assess control performance, a dynamic response test, more specifically, a step response, was employed. From a starting level of 10 cm to a setpoint of 25 cm, data was recorded every two seconds. The study includes critical performance metrics such as rising time, settling time (within ±5% tolerance), overshoot, and steady-state error. With a rising time of 9.22 seconds, a settling time of 14 seconds, an overshoot of 2.0%, and no steady-state error, the data showed that the system steadily approached the intended setpoint. These findings demonstrate that integrating a PLC and HMI provides reliable water tank level monitoring and control and is suitable for use as an automation solution in industrial settings.
