Abstract

Rendahnya literasi keuangan masyarakat masih menjadi persoalan serius di era digital, terutama terkait meningkatnya kasus pinjaman online ilegal yang berimplikasi negatif terhadap stabilitas ekonomi keluarga. Kegiatan pengabdian kepada masyarakat yang dilaksanakan di Kecamatan Harau ini bertujuan untuk meningkatkan pemahaman dan keterampilan pengelolaan keuangan rumah tangga melalui edukasi keuangan yang berfokus pada empat aspek utama: bahaya pinjaman online ilegal, manajemen keuangan keluarga, pemanfaatan aplikasi keuangan digital, dan praktik pinjam-meminjam dalam perspektif agama. Metode yang digunakan meliputi ceramah interaktif, diskusi, dan praktik penggunaan aplikasi keuangan, dengan evaluasi capaian peserta melalui instrumen pre-test dan post-test. Hasil pengukuran menunjukkan adanya peningkatan signifikan pada seluruh indikator, yaitu pemahaman risiko pinjaman online meningkat dari 58,9 menjadi 83,6, manajemen keuangan keluarga dari 83,7 menjadi 93,2, literasi aplikasi keuangan dari 62,5 menjadi 86,2, dan pemahaman pinjaman online dalam perspektif agama dari 74,3 menjadi 89,6. Temuan ini mengindikasikan bahwa pendekatan edukasi keuangan yang terintegrasi dengan nilai agama serta pemanfaatan teknologi finansial mampu memperkuat literasi keuangan keluarga dan berperan sebagai strategi preventif dalam mengurangi risiko pinjaman online bermasalah

Abstract

Community health centers (Puskesmas) play a crucial role in providing primary healthcare services. However, long patient queues often reduce service efficiency and patient satisfaction. This study analyzes queue performance at a Puskesmas outpatient clinic using the M/M/1 queuing model to evaluate waiting time and service effectiveness. Data were collected through seven days of field observations, recording patient arrival patterns and service times during operational hours. The results show that the patient arrival rate is  patients per minute, while the service rate is  patients per minute. The system operates under a stable condition with a utilization factor of . The average waiting time in the queue is  minutes, whereas the total time spent in the system is  minutes, indicating that a significant proportion of patient time is spent waiting for service. The originality of this study lies in its empirical application of the M/M/1 queuing model to a real outpatient healthcare system in a Puskesmas setting, providing practical performance indicators that can support operational decision-making in primary healthcare services. However, the study is limited by a relatively short observation period of seven days and data collected from a single healthcare facility, meaning the findings reflect local conditions and cannot be generalized to other healthcare centers with different operational characteristics. The study recommends improving workforce management and implementing a structured patient scheduling system to reduce waiting time and enhance service efficiency.

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.

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.
