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.

Abstract

Abstrak: Kemampuan dan minat membaca siswa Sekolah Dasar Negeri 123 Pekanbaru masih tergolong rendah berdasarkan hasil observasi awal. Tujuan utama kegiatan pengabdian ini adalah untuk memberikan dasar kecintaan dan juga pemahaman literasi pada siswa sekolah dasar negeri 123 Pekanbaru seperti membaca dan juga memahami isi bacaan. Metode yang dipakai dalam kegiatan pengabdian ini yaitu metode pendampingan dimana tim pengabdi melakukan pendampingan kepada siswa untuk melaksanakan program one day one story. Tahapan pada pengabdian ini meliputi: (1) persiapan yang terdiri dari observasi dan perencanaan program; (2) pelaksanaan program yaitu one day one story; dan (3) evaluasi program. Mitra pada kegiatan pengabdian ini yaitu siswa kelas 5 sekolah dasar negeri 123 Pekanbaru yang berjumlah 30 siswa. Ketercapaian kegiatan pengabdian diukur melalui instrument soal Pre-Test dan Post-Test. Hasil dari kegiatan ini dapat diketahui dengan adanya program one day one story yang dilaksanakan terbukti mampu meningkatkan kemampuan dan juga minat siswa dalam hal literasi. Terjadi peningkatan minat siswa dalam membaca dengan persentase nilai N-Gain sebesar 58.8% dan penguasaan siswa dalam memahami bacaan juga terjadi peningkatan sebesar 66.67%.Abstract: The reading ability and interest of students at Sekolah Dasar Negeri 123 Pekanbaru have been observed to be relatively low based on initial observations. The primary objective of this community service initiative is to foster a foundation of love for reading and literacy comprehension among students at State Elementary School 123 Pekanbaru, encompassing reading skills and understanding the content of texts. The method employed in this service activity is an accompaniment approach, where the service team provides guidance to students in implementing the "One Day One Story" program. The stages of this service activity include: (1) preparation, which consists of observation and program planning; (2) program implementation, specifically the "One Day One Story" initiative; and (3) program evaluation. The partners involved in this activity are 30 fifth-grade students from State Elementary School 123 Pekanbaru. The success of this service activity is measured through Pre-Test and post-test instruments. The results of the activity indicate that the implementation of the "One Day One Story" program has effectively enhanced both the reading ability and interest of the students in literacy. There was an increase in students' interest in reading, with an N-Gain score of 58.8%, and a significant improvement in their comprehension of reading material, with a 66.67% increase.

Abstract

Accurate quantity take-off is essential for reliable construction cost estimation, particularly in reinforced concrete works, which involve complex and error-prone calculations. This study evaluates the accuracy of BIM 5D-based quantity take-off and examines cost deviations compared to conventional contractor estimations. A three-story dormitory building was modeled using BIM 5D (Cubicost), and the results were validated against manual analytical calculations. The validation shows strong agreement, with a maximum deviation of 0.75% and a high linear correlation across concrete, reinforcement, and formwork quantities. A comparative analysis with the contractor’s Bill of Quantity reveals a cost difference of approximately 3.4%, with the contractor’s estimate being higher. This deviation is primarily attributed to simplifications in conventional methods, including double counting at element interfaces, generalized reinforcement detailing, and the inclusion of material allowances. In contrast, BIM 5D enables a more integrated and precise estimation by accounting for element interactions and optimizing reinforcement configurations. However, the results also highlight that BIM-based estimation is sensitive to modeling assumptions and parameter settings. Therefore, aligning BIM models with actual construction practices is essential to ensure reliable and applicable results. Overall, this study demonstrates the potential of BIM 5D to enhance the accuracy, consistency, and transparency of construction cost estimation.
