Abstract

In today's digital era, the Rapid Application Development (RAD) method has shown great potential across various sectors, including education and career development. However, its application in electronic career systems, or E-Careers, remains relatively uncommon. This creates an urgency to conduct research on how the Rapid Application Development (RAD) method can be applied in E-Career systems to enhance efficiency, transparency, and security in the career search process for students. This study aims to apply the Rapid Application Development (RAD) method in the development of a mobile-based E-Career system at Politeknik LP3I Cirebon Campus. One sector that can benefit from the Rapid Application Development (RAD) method is the electronic career system or E-Career. This system aims to facilitate career searches for students in a more efficient and transparent manner. However, a challenge in implementing this system is ensuring that the data shared between different parties is secure and unalterable. The primary goal is to create a system that is not only efficient but also secure and transparent. Thus, students can search for careers more efficiently and transparently, while companies can more easily find the right candidates. Additionally, this research also aims to identify and address challenges in integrating the Rapid Application Development (RAD) method with mobile applications.

Abstract

Excellent Lecturers are human resources (HR) that are very necessary in the world of education so that they can educate students to become superior human resources. Apart from that, all universities in Indonesia play an active role in improving the quality of education. One important factor that determines the quality of education in higher education is the quality of the lecturers who teach. Excellent lecturers are lecturers who are sought after and needed by all universities. However, in reality, the lecturer recruitment process in educational institutions often experiences obstacles, such as inaccurate decisions, errors in decision making, and late decision making. This can affect the quality of education provided and the effectiveness of the educational institution itself. Therefore, selecting superior and qualified lecturers is very important. So, we need a decision support system to help the recruitment process for superior lecturers more effectively and efficiently. Manual decision making in the recruitment process is considered less objective and can result in decisions that are not in accordance with wishes. The Multi-Criteria Decision Making (MCDM) method is a method that can be used to assist decision making in deciding which superior lecturers to recruit. The urgency of this research is to help make decisions effectively and efficiently. The aim of this research is to build a decision support system for the lecturer recruitment process using the web-based Multi-Criteria Decision Making (MCDM) method.

Abstract

Indonesia's National Data Center (PDN) has a strategic role in the country's digital infrastructure, but it is a potential target for cyberattacks. Conventional security models have proven inadequate in dealing with the complexity of modern threats, so a Zero Trust Architecture (ZTA) approach is necessary. This research aims to develop a Zero Trust security framework that is integrated with blockchain technology to improve the efficiency and resilience of PDN systems. The research methods include literature study, identification of PDN security needs, framework design, prototype development using Hyperledger Fabric, and testing and evaluation in a simulation environment. The framework built consists of blockchain-based identity verification, minimum access control (least privilege), and blockchain-based activity monitoring and logging. Provisional results show that the framework successfully rejects 98% of simulated internal attacks, reduces the success of unauthorized access by 80%, and reduces the success of phishing attacks from 25% to 5%. A survey of administrators showed that 90% said security improvements and 85% said the system remained user-friendly. While providing significant improvements in security and auditability, this framework creates an additional latency of 100–150 ms and demands expert human resources. This research contributes to the development of a more transparent and resilient national security model through the integration of blockchain and Zero Trust principles.

Abstract

The rapid advancement of the digital industry requires vocational education in Indonesia to undergo transformation, particularly in providing competency validation systems that are efficient, adaptive, and trustworthy. In reality, however, competency certification processes in many vocational institutions are still conducted manually and tend to be bureaucratic, limiting their ability to respond to the dynamic needs of industry. This condition may reduce graduates’ competitiveness and widen the skills gap between vocational education and the labor market. Micro-credentials have emerged as an innovative approach to recognizing competencies in a modular, flexible, and industry-oriented manner. Nevertheless, their implementation still faces significant challenges, especially in terms of validation speed, reliability, and transparency. To address these challenges, this study develops a micro-credential–based competency validation model integrated with blockchain technology through the use of smart contracts at Politeknik LP3I Medan. This research adopts a Research and Development (R&D) approach based on the Borg and Gall model, including needs analysis, learning module design, system development, limited trials, expert validation, and effectiveness evaluation. Alpha testing involving 15 students demonstrates a system success rate of 95%, with an average verification time of 14.4 seconds. Usability evaluation indicates that the system is user-friendly and well accepted.

Abstract

The water quality of the Ciujung River in Serang has experienced a significant decline due to domestic and industrial waste pollution, directly affecting public health and environmental sustainability. Current monitoring systems remain largely manual and lack responsiveness, resulting in delayed and less data-driven pollution management. This study aims to develop an Internet of Things (IoT)-based water quality monitoring system integrated with an intelligent dashboard to support sustainable environmental programs. The proposed system monitors key water quality parameters, including pH, temperature, turbidity, and total dissolved solids (TDS), in real time. The methodology includes designing a microcontroller-based sensor prototype, integrating data communication modules (LoRa/GSM), processing data via a cloud server, and implementing interactive visualization through a web-based dashboard. Furthermore, the system features an early warning mechanism when water parameters exceed environmental quality thresholds. Field trials are conducted at several strategic points along the Ciujung River to evaluate data acquisition reliability, connectivity stability, and sensor accuracy. The expected outcome is an efficient, responsive, and adaptive monitoring system that supports data-driven decision-making in river water management and reinforces commitments to sustainable development.
