<![CDATA[The rapid development of digital technology encourages the importance of developing digital literacy in students. This study aims to reveal the relationship between digital literacy and student learning outcomes at SMK Negeri 1 Painan. Quantitative research methods with simple random sampling techniques were used in this study. Data analysis was carried out using normality, homogeneity, linearity, and Pearson correlation tests. The results of the study showed a positive relationship between digital literacy and student learning outcomes, although the correlation found was relatively weak (r = 0.372, p < 0.05). This finding indicates that increasing digital literacy can contribute to improving student learning outcomes. However, further research is needed with more specific variables to reveal the influence of digital literacy in more depth. The results of this study provide important implications for the development of curriculum and learning that integrates digital literacy to improve the quality of education.]]>

<![CDATA[This study aims to analyze the queuing system and optimize services at Indomaret Padang Bulan Rantauprapat. Using the Multi-Channel Single-Phase queue model, the research identifies service levels and the optimal number of cashiers needed to minimize customer waiting time, especially during peak hours. Data was collected through direct observation over three days, between 12:00 PM and 8:00 PM, with the highest arrival rate observed from 4:00 PM to 5:00 PM. Calculations were conducted using QM for Windows software. The analysis results show an average server utilization rate of 17%, with nearly zero waiting time, indicating sufficient service capacity. These findings demonstrate that with two efficiently operated cashiers, Indomaret can provide optimal services without long queues, making it one of the retail stores with the best service system.]]>

<![CDATA[This study aims to analyze the queuing system at Miniso's services in Suzuya Mall Rantauprapat, focusing on queue patterns, service efficiency, and optimization solutions. Using the M/M/1 queue theory model, the study reveals an imbalance in service capacity, especially during peak hours, leading to increased customer waiting times and decreased satisfaction levels. Proposed solutions include adding more cashiers, implementing an electronic queue system, and scheduling work shifts based on data. These strategies are expected to reduce waiting times, enhance operational efficiency, and provide a better customer experience.]]>

<![CDATA[This research analyzes the single channel singlephase queuing model for public services at the Simpang Mangga Public Fuel Filling Station (SPBU). Public services play an important role in meeting the diverse needs of society, with efficiency and effectiveness becoming a major concern due to increasing public demands for quality services. Queuing models serve as a valuable approach to analyzing and optimizing service systems by understanding customer arrival patterns, service capacity, and service duration. This research uses quantitative methods with a descriptive-analytical approach, collecting data through direct observation for one hour to assess customer arrival times, service times and waiting times. The research results show that the average customer arrival interval is 5 minutes, with gas stations capable of serving 30 customers per hour. The level of service intensity (p) was recorded at 0.17, indicating that service facilities were only filled with customer service as much as 17%. The average number of customers in the system (L) is 0.2, and the average number of customers waiting (Lq) is 0.03. The average time spent by customers in the system (W) is 0.04 minutes, while the average waiting time in queue (Wq) is 0.01 minutes. These findings highlight the effectiveness of single-phase single-channel models in improving service efficiency and customer satisfaction. Recommendations include increasing service capacity and optimizing the queuing system to reduce waiting times and improve overall service quality.]]>

<![CDATA[Queue is an activity of waiting in a line carried out by customers or goods to obtain service facilities. Queue is a Waiting Line of Customers measured by certain units that require one or more services. Queue Analysis is a form of probability analysis. Queues are often encountered in everyday life. The queuing process is a process related to the arrival of customers at a service facility, waiting in a queue if they have not been served, being served and finally leaving the facility after being served. Someone has to wait which takes time. The purpose of this observation is to find out the queuing system at Indomaret Aek Batu and to find out the optimal cashier service. The first step taken is to observe customer arrivals. The analysis process uses "Microsoft Excel" and "POM-QM For Windows" software with the Waiting Lines module. From the results of the calculation, the average number of customers waiting for the longest system at 15.00-19.00 is 114 people. While the average number of customers waiting in the shortest system occurs at 07.00-11.00, which is 32 people, it can be concluded that the performance of the queue system at Indomaret Aek Batu is not optimal.]]>

<![CDATA[This research aims to apply the simplex method using QM for Windows software to determine the optimal benefits of the Yulia Sewing House. In the textile industry, efficient resource management is very important to increase profitability. Yulia Sewing House is faced with the challenge of utilising limited resources such as raw materials and labour to maximise profits from various products offered. The simplex method is used to solve linear program problems with the function of profit goals that want to be maximised and constraints such as production capacity or availability of raw materials. The data used in this research includes information on production costs, selling prices, and production capacity of each type of product. QM for Windows analyses to determine the optimal production mix. This research will make a significant contribution to strategic decision making in the management of Yulia Sewing House and can be a reference for other small and medium businesses to optimise the production process and increase the profitability of Yulia Sewing House. From the results thatObtained, the simplex method can be used to maximise. The profit with an increase in profit of Rp 2,800,000.]]>
