Abstract

Tujuan dari penelitian ini adalah untuk mengevaluasi kualitas layanan (QoS) jaringan internet di Alun-Alun Sidoarjo dengan menggunakan wireshark. Internet publik semakin dibutuhkan untuk berbagai keperluan, seperti komunikasi, hiburan, dan pekerjaan. Namun, kualitas jaringan di area publik seperti Alun-Alun Sidoarjo masih sering mengalami masalah, seperti koneksi lambat, keterlambatan pengiriman data (latensi), perubahan waktu pengiriman yang tidak stabil (jitter), dan kehilangan data (packet loss). Pada penelitian ini, dilakukan pengukuran langsung terhadap beberapa parameter utama, yaitu throughput, latensi, jitter, dan packet loss pada tiga waktu yang berbeda yakni pagi, siang, dan sore. Hasil analisis menunjukkan bahwa koneksi internet pada siang hari memiliki kecepatan transfer data (throughput) tertinggi sebesar 72 kbps dengan latensi paling rendah (22,8 ms). Sementara itu, pada pagi hari ditemukan jitter negatif (-0,599 ms), yang bisa memengaruhi layanan yang membutuhkan koneksi stabil secara real-time. Pada sore hari, tingkat kehilangan data (packet loss) paling rendah sebesar 0,109%, menunjukkan jaringan yang lebih stabil dibandingkan waktu lainnya. Berdasarkan hasil penelitian ini, kualitas layanan internet di Alun-Alun Sidoarjo masih tergolong cukup baik menurut standar TIPHON, meskipun ada perubahan kualitas pada waktu-waktu tertentu. Oleh karena itu, diperlukan peningkatan infrastruktur jaringan agar koneksi lebih stabil, terutama dalam mengatasi jitter negatif dan menjaga kestabilan kecepatan transfer data di semua waktu. The purpose of this study is to evaluate the quality of service (QoS) of the internet network in Sidoarjo's town square using Wireshark. Public internet is increasingly needed for various purposes, such as communication, entertainment, and work. However, network quality in public areas such as Sidoarjo's town square still often experiences problems, such as slow connections, delayed data transmission (latency), unstable transmission time changes (jitter), and data loss (packet loss). In this study, direct measurements were made of several key parameters, namely throughput, latency, jitter, and packet loss at three different times: morning, afternoon, and evening. The analysis results show that the internet connection during the day has the highest data transfer rate (throughput) of 72 kbps with the lowest latency (22.8 ms). Meanwhile, in the morning, negative jitter was found (-0.599 ms), which can affect services that require a stable connection in real-time. In the afternoon, the data loss rate (packet loss) was lowest at 0.109%, indicating a more stable network compared to other times. Based on the results of this study, the quality of internet service in Sidoarjo's town square is still considered quite good according to TIPHON standards, although there are occasional changes in quality. Therefore, network infrastructure improvements are needed to ensure more stable connections, particularly in addressing negative jitters and always maintaining stable data transfer speeds.

Abstract

Motion capture has been developed and applied in various fields, one of them is dancing. Remo dance is a dance from East Java that tells the struggle of a prince who fought on the battlefield. Remo dancer does not use body-tight costume. He wears a few costume pieces and accessories, so required a motion detection method that can detect limb motion which does not damage the beauty of the costumes and does not interfere motion of the dancer. The method is Markerless Motion Capture. Limbs motions are partial behavior. This means that all limbs do not move simultaneously, but alternately. It required motion tracking to detect parts of the body moving and where the direction of motion. Optical flow is a method that is suitable for the above conditions. Moving body parts will be detected by the bounding box. A bounding box differential value between frames can determine the direction of the motion and how far the object is moving. The optical flow method is simple and does not require a monochrome background. This method does not use complex feature extraction process so it can be applied to real-time motion capture. Performance of motion detection with optical flow method is determined by the value of the ratio between the area of the blob and the area of the bounding box. Estimate coordinates are not necessarily like original coordinates, but if the chart of estimate motion similar to the chart of the original motion, it means motion estimation it can be said to have the same motion with the original.Keywords: Motion Capture, Markerless, Remo Dance, Optical Flow
