Abstract

This paper proposes a load shedding scheme to improve voltage profile of a power system. A linear programming approach to optimal power flow is utilized to obtain optimum amount of load to shed in order to bring power system to an acceptable operating region. In this work, ±5% voltage variation is considered to be acceptable and hence, an immediate control action should be taken if power system is operated beyond this limit. The proposed method was tested on the IEEE 57-bus test system. Results showed that the proposed approach was able to provide a minimum amount of load shedding action to improve voltage profile of the studied power system.

Abstract

Education is fundamentally a process of shaping character and developing students' abilities. However, the expected educational outcomes have not been fully achieved, as evidenced by the low academic performance of many students. This study aims to examine aspects of curriculum implementation and the learning process. A qualitative research method was employed using a case study approach. The findings reveal that curriculum implementation, particularly in the learning process, involves student interaction with teachers and engagement with real-world problems both inside and outside the classroom. The stages of curriculum implementation consist of planning, implementation, and evaluation. Several factors hinder effective curriculum implementation, including a lack of teacher innovation, limited teacher skills and knowledge of new methodologies, inadequate facilities, misaligned policies, and low motivation to adopt innovations. Curriculum implementation is influenced by three main factors: curriculum characteristics, implementation strategies, and the characteristics of curriculum users.

Abstract

Companies no longer rely solely on manual cost recording, but instead utilize cloud-based systems, Enterprise Resource Planning (ERP), and business intelligence that provide real-time cost information. With this technology, managers can quickly analyze cost deviations, measure product profitability, and even adjust production strategies based on the latest data.Mastery of cost theory and concepts is a fundamental aspect in the fields of accounting and management, yet its application in real-world contexts often encounters various challenges. The gap between theoretical understanding gained in academic settings and the practical needs of cost management has led both students and practitioners to face difficulties in accurately identifying and classifying costs. To bridge this gap, innovative learning methods are required, such as the use of business simulations, field case studies, and collaboration with industry. In addition, the integration of digital technology and modern accounting software is crucial to strengthen the curriculum and align it with the demands of the digital era. Therefore, the implementation of collaborative, practice-based, and technology-integrated approaches is expected to enhance the competence of students and practitioners in both understanding and applying cost theory effectively within business and organizational contexts.
