Abstract

This study aims to develop and implement an efficient and effective e-commerce-based electronic goods sales system using the Extreme Programming (XP) system development method. The main focus of this research is to enhance the promotion and sales processes in small and medium-sized stores to be competitive in the digital era. XP was chosen due to its iterative and incremental approach and customer involvement at every stage of software development to ensure the final product meets user needs and expectations. The results indicate that the developed system can expand customer reach and improve the operational efficiency of these stores.

Abstract

This study aims to systematically investigate the influence of principal leadership on teacher performance through a Systematic Literature Review (SLR) approach. A total of fifteen peer-reviewed journal articles published between 2020 and 2024 in Indonesia were analyzed to identify patterns, findings, and research gaps related to this topic. The results indicate that leadership styles particularly transformational, democratic, and control based positively affect teacher performance, although the magnitude of influence varies depending on contextual and mediating factors such as work motivation, organizational culture, and infrastructure management. The novelty of this review lies in mapping the interplay between leadership styles and school-specific contextual variables, a dimension underexplored in previous studies. This study contributes to educational leadership literature by providing evidence-based recommendations for developing adaptive leadership models tailored to school characteristics. It also highlights the need for further qualitative exploration to understand the emotional and relational dynamics between school leaders and teachers in diverse educational settings.
