Abstract

Pangkalan Sudiawati Bekasi is a business engaged in household goods distribution with a central warehouse that stores various products. However, the sales data management process is still conducted manually through bookkeeping, which often leads to recording errors and difficulties in identifying the most demanded products. This issue results in ineffective decision-making regarding stock procurement, potentially causing losses due to unsold products. This study aims to design a sales data management system that can effectively identify best-selling products. The approach used in this research is the CRISP-DM (Cross-Industry Standard Process for Data Mining) methodology as a system development framework, combined with the K-Means Clustering algorithm to group sales data based on product demand levels. The results of this study indicate that the developed system is capable of classifying products into several categories, such as highly demanded, moderately demanded, and less demanded products. This classification assists Pangkalan Sudiawati in making more accurate decisions regarding inventory management and improving the efficiency of sales data processing.

Abstract

Laboratorium komputer Fakultas Ilmu Komputer Universitas Bhayangkara Jakarta Raya (Fasilkom Ubhara) sebelumnya bergantung pada jaringan hotspot dari provider ISP yang tidak dapat dikonfigurasi secara mandiri, sehingga tidak tersedia mekanisme pembatasan bandwidth, manajemen pengguna, maupun autentikasi akses yang memadai. Kondisi ini menyebabkan penggunaan bandwidth yang tidak terkontrol dan ketidakmampuan administrator dalam memonitor aktivitas jaringan. Penelitian ini bertujuan untuk mengimplementasikan infrastruktur jaringan WLAN mandiri berbasis MikroTik RouterOS yang dilengkapi dengan manajemen hotspot menggunakan captive portal dan pembatasan bandwidth melalui Simple Queue. Metode yang digunakan adalah Network Development Life Cycle (NDLC) yang mencakup tahapan analisis, desain, simulasi, implementasi, monitoring, dan manajemen. Hasil implementasi menunjukkan bahwa jaringan WLAN berhasil dibangun dengan konektivitas penuh ke internet (packet loss 0%, avg-rtt 1ms), pembatasan bandwidth efektif pada 5 Mbps upload/download per segmen jaringan dengan hasil speedtest mencapai 4,31 Mbps download dan 4,72 Mbps upload, serta sistem hotspot captive portal yang berfungsi dengan autentikasi berbasis username dan password melalui domain labsiber.com. Penelitian ini menyimpulkan bahwa implementasi MikroTik secara signifikan meningkatkan kontrol administrator terhadap jaringan laboratorium dibandingkan kondisi sebelumnya.

Abstract

Augmented reality (AR) has become a pivotal tool for enhancing museum engagement through interactive experiences. This study developed and evaluated an Android-based AR application for the Popa Eyato Archaeological Museum, comparing marker-based (Vuforia), and markerless (EasyAR) tracking methods. While previous studies often focus on technical development, this research provides empirical insights into usability within the Southeast Asian Museum context. Using a mixed-methods approach with 35 participants, the application was evaluated using the system usability scale (SUS) and handheld augmented reality usability scale (HARUS). Results show that the application achieved an average SUS score of 78, classified as “Good” and “Acceptable”. The comparative analysis reveals that while marker-based AR offers higher stability, markerless AR provides greater flexibility for spatial exploration. However, environmental factors like museum lighting significantly impact markerless tracking performance. These findings offer practical recommendations for museum curators and AR designers in selecting appropriate tracking technologies based on infrastructural constraints and visitor demographics. The study concludes that balancing technical stability with user mobility is essential for optimizing digital heritage preservation and educational engagement in regional museums.
