Abstract

Abstract: This study is motivated by the underutilization of transaction data at Toko F3I Kisaran in supporting decision-making related to inventory and pricing strategies. Currently, decisions are made conventionally based on experience, which may lead to overstock or stockout conditions. This research aims to develop a sales prediction model by applying Data Mining techniques using the Multiple Linear Regression method to analyze the influence of stock and price variables on sales. The research methodology includes historical data collection, regression analysis, web-based system design using PHP and MySQL, and system testing through the Black Box method. The results indicate that the developed model is capable of generating measurable and systematic sales estimations based on stock and price variables. The implementation of this system can assist store management in planning inventory levels and pricing strategies more efficiently, thereby improving operational effectiveness and business competitiveness.

Abstract

Abstract: The development of network infrastructure in higher education environments demands a monitoring system capable of detecting disruptions quickly and accurately. Royal University does not yet have an integrated and real-time network monitoring system, so network administrators often discover disruptions after receiving reports from users. This condition results in slow response to disruption handling and suboptimal network performance. This study aims to implement The Dude as a network monitoring system to support the optimization of Royal University's network infrastructure performance. The research method used is a qualitative approach with the stages of problem identification, literature study, system analysis, system design, implementation, and system testing. The monitoring system is implemented with The Dude Server architecture running on MikroTik CHR, while The Dude Client is used by the administrator via a laptop. The results show that the system is capable of performing network discovery, monitoring device status in real-time, displaying network topology visualization, recording monitoring history, and providing notifications when disruptions occur. System testing proves that all monitoring functions run according to the analyzed requirements. Thus, the implementation of The Dude is proven effective in increasing the speed of disruption detection, troubleshooting efficiency, and optimizing the network performance of Royal University. Keywords: mikrotik; network monitoring; network discovery; network optimization; the dude Abstrak: Perkembangan infrastruktur jaringan di lingkungan perguruan tinggi menuntut adanya sistem pemantauan yang mampu mendeteksi gangguan secara cepat dan akurat. Universitas Royal belum memiliki sistem monitoring jaringan yang terintegrasi dan real-time, sehingga administrator jaringan sering mengetahui gangguan setelah menerima laporan dari pengguna. Kondisi ini berdampak pada lambatnya respons penanganan gangguan serta kurang optimalnya kinerja jaringan. Penelitian ini bertujuan untuk mengimplementasikan The Dude sebagai sistem monitoring jaringan guna mendukung optimalisasi kinerja infrastruktur jaringan Universitas Royal. Metode penelitian yang digunakan adalah pendekatan kualitatif dengan tahapan identifikasi masalah, studi literatur, analisis sistem, perancangan sistem, implementasi, dan pengujian sistem. Sistem monitoring diimplementasikan dengan arsitektur The Dude Server yang berjalan pada MikroTik CHR, sedangkan The Dude Client digunakan oleh administrator melalui laptop. Hasil penelitian menunjukkan bahwa sistem mampu melakukan network discovery, memantau status perangkat secara real-time, menampilkan visualisasi topologi jaringan, mencatat histori monitoring, serta memberikan notifikasi ketika terjadi gangguan. Pengujian sistem membuktikan bahwa seluruh fungsi monitoring berjalan sesuai dengan kebutuhan yang telah dianalisis. Dengan demikian, implementasi The Dude terbukti efektif dalam meningkatkan kecepatan deteksi gangguan, efisiensi troubleshooting, dan optimalisasi kinerja jaringan Universitas Royal.

Abstract

Abstract: The development of information and communication technology has increased public demand for digital services, particularly data packages as the primary means of internet access. This high demand requires data package retailers to manage inventory optimally to ensure product availability meets customer needs. At CMC Cell, the determination of data package stock is still based on intuition without systematic data analysis, resulting in stock accumulation for certain products and stock shortages for others when demand increases. This study aims to design and implement a web-based Decision Support System (DSS) using the Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) method to determine the optimal stock of data packages. The MOORA method is applied to rank data package alternatives based on several criteria, including data package demand, sales history, remaining stock, selling price, and validity period. Sales data are analyzed using the calculation stages of the MOORA method. The results show that the Telkomsel V 3 GB data package achieves the highest preference value of 0.1498 and is therefore recommended as the top-priority data package, with an optimal stock quantity of 200 units. With the implementation of this system, the recommendations for determining data package stock become more measurable, objective, and data-driven. Keywords: MOORA; PHP; decision support system; optimal stock; stock priority Abstrak: Perkembangan teknologi informasi dan komunikasi telah meningkatkan kebutuhan masyarakat terhadap layanan digital, khususnya paket data sebagai sarana utama akses internet. Tingginya permintaan tersebut menuntut pelaku usaha penjualan paket data untuk mampu mengelola stok secara optimal agar ketersediaan produk sesuai dengan kebutuhan pelanggan. Pada Toko CMC Cell, penentuan stok paket data masih dilakukan berdasarkan intuisi tanpa analisis data yang sistematis, sehingga sering terjadi penumpukan stok pada beberapa produk dan kekosongan stok pada produk lain saat permintaan meningkat. Penelitian ini bertujuan untuk merancang dan mengimplementasikan Sistem Pendukung Keputusan (SPK) berbasis web menggunakan metode Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) dalam menentukan stok optimal paket data. Metode MOORA digunakan untuk melakukan perangkingan alternatif paket data berdasarkan beberapa kriteria, yaitu permintaan paket data, riwayat penjualan, jumlah stok tersisa, harga jual, dan masa aktif. Data penjualan paket data dianalisis menggunakan tahapan perhitungan metode MOORA. Hasil penelitian menunjukkan bahwa paket data Telkomsel V 3 GB memperoleh nilai preferensi tertinggi sebesar 0,1498 sehingga direkomendasikan sebagai paket data dengan prioritas stok tertinggi, dengan jumlah stok optimal sebanyak 200 pcs. Dengan adanya sistem ini, rekomendasi penentuan stok paket data yang dihasilkan menjadi lebih terukur, objektif, dan berbasis data.
