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.
