Abstract

Queueing system modeling and simulation is an effective approach for analyzing service performance in business environments with dynamic customer arrival rates, such as at King Kuphi Cafe. This study aims to model the queueing system at the cafe with various variations in customer arrival rates using the queueing theory approach and simulate it using the Python programming language. The models used are the M/M/1 and M/M/c queueing systems, which allow analysis of changes in waiting time, queue length, server utilization, and service level based on variations in arrival (λ) and service (μ) parameters. The simulation was run using Python packages such as NumPy and SimPy to represent the arrival and service processes realistically. The results of the study show that an increase in the rate of customer arrivals significantly affects system performance, particularly in terms of an increase in average waiting time and queue length. In addition, adding more servers has been proven to reduce queue congestion and improve overall service quality. These findings are expected to serve as a basis for King Kuphi Cafe managers in making strategic decisions regarding the number of baristas and operational optimization to achieve more efficient service.

Abstract

This study aims to address issues in employee leave data management at the Deli Serdang District Agricultural Office, where leave records were previously processed manually using separate documents, resulting in data duplication, inaccuracies, and delays in preparing reports. To solve this problem, a web-based Employee Leave Record Management System was developed using the Waterfall model through stages of requirements analysis, system design, implementation, testing, and maintenance. System evaluation was conducted using Black-Box testing to verify functional performance. The system supports structured recording of employee leave information, employee profile data such as position and department, and provides real-time reporting features to support administrative decision-making. The application was developed using the CodeIgniter-based MVC architecture and MySQL database, which enhances data accuracy, information accessibility, and administrative efficiency. The results demonstrate that the system successfully minimizes recording errors and improves the effectiveness of leave data management. Future development opportunities include integrating automated online leave request and approval workflows, mobile access features, and notification services to maximize usability and system automation.

Abstract

Wd Advertising Medan merupakan UMKM jasa pembuatan huruf timbul dan neon box yang masih mengandalkan promosi konvensional melalui media sosial sehingga jangkauan pemasaran dan penyampaian informasi layanan belum optimal. Kegiatan pengabdian ini bertujuan mendukung transformasi digital usaha melalui perancangan dan pembangunan website sebagai media promosi dan pelayanan informasi. Metode pelaksanaan meliputi observasi kebutuhan, perancangan antarmuka, pengembangan website, uji fungsional, serta pelatihan pengelolaan konten kepada pemilik usaha. Hasil kegiatan menghasilkan website informatif yang memuat profil usaha, katalog layanan, portofolio, blog artikel, dan kontak layanan. Evaluasi kuantitatif mitra menunjukkan skor rata-rata 94/100 dan diproyeksikan dapat meningkatkan efektivitas promosi hingga ±70% serta menarik 6–10 calon pelanggan baru per bulan setelah website dipublikasikan. Novelty kegiatan terletak pada pengembangan website yang tidak hanya fokus pada promosi, tetapi juga pada kesiapan keberlanjutan melalui pelatihan pengelolaan konten secara mandiri. Kegiatan ini menunjukkan bahwa digitalisasi berbasis website mampu meningkatkan profesionalitas dan daya saing UMKM.
