Abstract

Abstract: This community service activity aims to introduce Optical Line Terminal (OLT) technology as the main device in GPON-based Fiber to the Home (FTTH) access networks to students of SMK Negeri 1 BP Mandoge in order to improve their technical understanding regarding fiber optic network management. The main problem faced is the limited knowledge of students regarding optical access network architecture, OLT-ONU communication mechanisms, and service and bandwidth management. The methods used include observation, interviews, direct practice, and question and answer sessions. The practical activities focused on introducing OLT device architecture, basic GPON concepts, logical port configuration, service VLAN management, and network performance monitoring. The results of the activity showed an increase in students' technical understanding of fiber optic network operation and management. This activity supports the improvement of student competencies according to the needs of the telecommunications industry. Keywords: GPON; network management; OLT; vocational education; fiber optic Abstrak: Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengenalkan teknologi Optical Line Terminal (OLT) sebagai perangkat utama dalam jaringan akses Fiber to the Home (FTTH) berbasis GPON kepada siswa SMK Negeri 1 BP Mandoge guna meningkatkan pemahaman teknis mereka terkait manajemen jaringan serat optik. Permasalahan utama yang dihadapi adalah keterbatasan pengetahuan siswa mengenai arsitektur jaringan akses optik, mekanisme komunikasi OLT–ONU, serta pengelolaan layanan dan bandwidth. Metode yang digunakan meliputi observasi, wawancara, praktik langsung, dan sesi tanya jawab. Kegiatan praktik difokuskan pada pengenalan arsitektur perangkat OLT, konsep dasar GPON, konfigurasi logis port, pengelolaan VLAN layanan, serta monitoring kinerja jaringan. Hasil kegiatan menunjukkan peningkatan pemahaman teknis siswa terhadap pengoperasian dan manajemen jaringan serat optik. Kegiatan ini mendukung peningkatan kompetensi siswa sesuai kebutuhan industri telekomunikasi. Kata kunci: GPON; manajemen jaringan; OLT; pendidikan vokasi; serat optik

Abstract

Abstract: This research aims to design and implement a web-based Optical Line Terminal (OLT) network monitoring system to detect congestion in real-time on Gigabit Passive Optical Network (GPON) architecture. The main problem in GPON networks is the increase in customer traffic which causes bandwidth bottlenecks and decreases Quality of Service (QoS). The research methodology includes analysis of OLT performance parameters (throughput, utilization, packet loss, latency), design of a system architecture based on SNMP and REST API, development of a monitoring dashboard using a web framework, and testing in an operational network environment. The developed system is able to display PON port status, bandwidth utilization level, and automatic notification when the congestion threshold is exceeded. The test results show that the system can detect an increase in utilization above 80% with a response time of less than 5 seconds. The implementation of this system increases the effectiveness of network monitoring and speeds up the troubleshooting process by administrators. Keywords: Network Monitoring; OLT; GPON; Congestion; Real-Time. Abstrak: Penelitian ini bertujuan merancang dan mengimplementasikan sistem monitoring jaringan Optical Line Terminal (OLT) berbasis web untuk mendeteksi congestion secara real-time pada arsitektur Gigabit Passive Optical Network (GPON). Permasalahan utama pada jaringan GPON adalah meningkatnya trafik pelanggan yang menyebabkan bottleneck bandwidth dan penurunan Quality of Service (QoS). Metodologi penelitian meliputi analisis parameter performa OLT (throughput, utilization, packet loss, latency), perancangan arsitektur sistem berbasis SNMP dan REST API, pengembangan dashboard monitoring menggunakan framework web, serta pengujian pada lingkungan jaringan operasional. Sistem yang dikembangkan mampu menampilkan status port PON, tingkat utilisasi bandwidth, dan notifikasi otomatis ketika threshold congestion terlampaui. Hasil pengujian menunjukkan bahwa sistem dapat mendeteksi kenaikan utilisasi di atas 80% dengan waktu respons kurang dari 5 detik. Implementasi sistem ini meningkatkan efektivitas monitoring jaringan serta mempercepat proses troubleshooting oleh administrator. Kata Kunci: Monitoring Jaringan; OLT; GPON; Congestion; Real-Time.

Abstract

Abstract: Hospitals, as healthcare facilities, have a high level of visitor mobility, particularly in inpatient wards. Therefore, visitor control is necessary to maintain patient comfort, safety, and service quality. Manual visitor monitoring is considered ineffective and prone to errors. Therefore, this study aims to design and implement an artificial intelligence-based visitor monitoring system for hospital inpatient wards using computer vision technology. The developed system utilizes the YOLOv8 model as an object detection algorithm to automatically detect and count visitors through a camera. Visitor information is displayed through a desktop-based monitoring interface and is equipped with warning notifications via the Telegram application and an automatic alarm if the number of visitors exceeds the limit set by hospital policy. Test results show that the system is capable of performing well in detecting and counting visitors in real time, as well as sending information and warnings responsively. Thus, this system is considered effective as a technology-based hospital management support solution in controlling inpatient ward density and making decisions more quickly and accurately. Keywords: hospital; inpatient ward; computer vision; yolov8; visitor monitoring Abstrak: Rumah sakit sebagai fasilitas pelayanan kesehatan memiliki tingkat mobilitas pengunjung yang tinggi, khususnya pada ruang rawat inap, sehingga diperlukan pengendalian jumlah pengunjung untuk menjaga kenyamanan, keselamatan pasien, dan kualitas pelayanan. Pemantauan jumlah pengunjung secara manual dinilai kurang efektif dan rentan terhadap kesalahan. Oleh karena itu, penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem pemantauan jumlah pengunjung ruang rawat inap rumah sakit berbasis kecerdasan buatan menggunakan teknologi computer vision. Sistem yang dikembangkan memanfaatkan model YOLOv8 sebagai algoritma object detection untuk mendeteksi dan menghitung jumlah pengunjung secara otomatis melalui kamera. Informasi jumlah pengunjung ditampilkan melalui antarmuka pemantauan berbasis desktop dan dilengkapi dengan notifikasi peringatan melalui aplikasi Telegram serta alarm otomatis apabila jumlah pengunjung melebihi batas yang ditetapkan sesuai kebijakan rumah sakit. Hasil pengujian menunjukkan bahwa sistem mampu bekerja dengan baik dalam mendeteksi dan menghitung jumlah pengunjung secara real-time, serta mengirimkan informasi dan peringatan secara responsif. Dengan demikian, sistem ini dinilai efektif sebagai solusi pendukung manajemen rumah sakit berbasis teknologi dalam pengendalian kepadatan ruang rawat inap dan pengambilan keputusan yang lebih cepat dan akurat. Kata kunci: rumah sakit; ruang rawat inap; computer vision; yolov8; monitoring pengunjung
