Abstract

This study examines the strategic role of administrative functions in enhancing the efficiency of Human Resource Management (HRM) in Indonesian tax offices. Using a descriptive qualitative case study approach, data were collected through interviews, document analysis, and direct observation at two regional tax offices. The findings reveal that structured and digitized administrative systems significantly improve the performance of key HR functions, including recruitment, payroll, training, and employee data management. Efficiency scores in administratively supported environments were consistently higher—averaging 27.9% more—than in settings lacking such support. Notably, digital tools reduced processing time, minimized errors, and strengthened transparency and accountability. The study concludes that administration must be reframed from a support function to a strategic enabler within HRM. Strengthening administrative capacity is essential for improving institutional effectiveness, especially in the public sector context.

Abstract

A student's ability to solve math problems is very, very low because in solving math problems, the learning process does not accustom students to think more creatively. This is because the learning process in the teacher's class still applies conventional methods, and the students in the class have not yet achieved scores above the KKM. This study aims to see the Creative Problem Solving learning model as a series of learning in solving and solving problems systematically based on student creativity to produce effective solutions. This research is a quasi-experimental research using purposive sampling technique. The instrument used in this research is a test of the ability to solve mathematical problems in the form of a written test, a result test and an observation sheet on the implementation of the learning process. The data analysis techniques used are descriptive statistical analysis and inferential statistical analysis. The results of the study show that the mathematics learning of students using the CPS learning model on the ability to solve mathematical problems of students is better than the results of mathematical learning of students who have followed conventional learning which means that there is an influence of creative problem solving learning on the ability to solve mathematical problems of high school students regarding linear inequalities .

Abstract

This study investigates the administrative management challenges faced by educational institutions in Labuhanbatu Regency and explores strategic solutions adopted by selected schools. Using a qualitative case study approach, data were collected through interviews, document analysis, and observations involving 15 stakeholders from ten institutions. The findings reveal systemic issues, including an absence of local policy guidelines for principal tenure, political interference in leadership appointments, inadequate digital proficiency among administrative staff, and a lack of structured performance evaluation. These challenges have led to frequent leadership turnover, inefficiency in school operations, and employee burnout. However, several high-performing schools have implemented effective solutions, such as internal training workshops, Total Quality Management (TQM) practices, and participatory leadership, resulting in measurable improvements in administrative efficiency and stakeholder satisfaction. The study concludes that while administrative problems are multifaceted, they can be addressed through targeted institutional reforms supported by policy and capacity-building initiatives.

Abstract

This study explores the implementation of digital-based archive and document management strategies at Labuhanbatu High School, focusing on their effectiveness, usability, resource readiness, and operational challenges. Employing a mixed-methods approach, the research involved surveys, interviews, and observations with 30 participants comprising administrative staff, teachers, and IT personnel. The results revealed a high level of effectiveness (mean score: 4.2) and usability (mean score: 4.0), indicating that the system significantly improved document accuracy, retrieval speed, and user accessibility. However, the readiness of human resources (mean score: 3.8) and infrastructure limitations, such as insufficient storage and unstable internet, were identified as critical areas needing improvement. Organizational barriers, including the absence of formal SOPs and limited budget, also hindered optimal implementation. The findings suggest that comprehensive training, structured policy support, and phased infrastructure development are essential to sustain and scale digital archiving systems in educational institutions.
