Abstract

This study focuses on the professionalism of teachers, particularly in terms of their attitudes and beliefs toward the integration of digital technology in teaching and learning activities. Plotagon was selected as a medium for developing interactive and contextual 3D instructional videos. The research employed a survey method aimed at exploring teachers’ interest in and acceptance of Plotagon as a supportive tool for instructional materials. The participants comprised twenty-eight junior high school teachers in Sawahlunto City. Prior to the survey, the teachers received intensive training on creating instructional videos using Plotagon. Data were collected through direct observation, questionnaires, and structured interviews. The findings reveal that the majority of teachers (91%) demonstrated positive beliefs regarding the use of digital culture-based technology through Plotagon, while 88% considered the medium beneficial for students. Furthermore, 86% of teachers showed high levels of engagement, and an equal proportion actively participated throughout the implementation process. These results imply that integrating digital storytelling platforms such as Plotagon can enhance teachers’ professional competence and foster innovative teaching practices.

Abstract

Queuing systems represent service processes in which customers wait due to limited service resources. Analysing such systems is essential to ensure efficient service and minimise waiting time. This study aims to examine the queuing system applied at Hokben Sawahan Padang by analysing customer arrival and service rates to determine the appropriate model and system characteristics. A quantitative method was used, with primary data collected through direct observation of arrival and service times. The results indicate that the appropriate model is (M/M/1) with a FIFO discipline. The average number of customers waiting in line (Lq) is 0.52 customers per minute, while the average number in the system (L) is 1.03 customers per minute. The average time spent in the system (W) is 4.9 minutes, and the average waiting time before service (Wq) is 2.4 minutes. The server utilisation level is 50.62%, with an idle rate of 49.38%. These findings suggest that the queuing system is relatively efficient and can be categorised as quite ideal. However, further improvements are needed to increase server utilisation and service effectiveness. Enhancing service quality, cleanliness, comfort, and overall operational performance can improve customer satisfaction and business profitability. The study implies that queue performance indicators, such as waiting time and utilisation rate, can serve as important managerial tools for evaluating and optimising service operations.
