Abstract

The web server is in charge of serving user requests and responding to users every time. The web server requires additional services without interrupting the running processes so that the server continues to function properly. This study aims to improve the performance of the web server in serving user requests to make it more optimal. Serving user requests more optimally can be done with scalability. Scalability is the addition of services on the server but does not affect server performance, this can be done by implementing Autoscaling. Autoscaling is used to improve the optimization of resource usage on a web server in order to maintain stable performance. To implement Autoscaling, a platform called Kubernetes can be used. The results of this study include five parameters, namely Scale Up, Scale Down, Throughput, Response Time, and CPU Usage and determine the durability of the web server. The final result shows that the web server is able to accept request loads of up to 1000000 connections with 10000 connections/second where the virtual web server that has used Autoscaling is able to save resources better than the web server that does not use Autoscaling with the difference from the Throughput parameter is 23.72 Kbps, the difference from the Response Time parameter is 5.16 requests/second, and the difference from the CPU Usage parameter is 5.72% where the average value of the Scale Up Parameter is 90 seconds then for the Scale Down parameter is 280 seconds with the average number of pods added is 5.33.Keywords - Autoscaling, Webserver, Kubernetes

Abstract

The reliability of medical Internet of Things (IoT) systems is critically dependent on network resilience, particularly in indoor hospital environments where conventional Wi-Fi infrastructures are vulnerable to single points of failure. Although ESP-Mesh has emerged as a promising self-healing communication protocol, its performance characteristics in medical IoT monitoring contexts remain insufficiently explored. This study aims to experimentally characterize the performance of ESP-Mesh networks for resilient medical IoT monitoring systems by analyzing multi-hop latency behavior, signal degradation, and communication stability under indoor medical-like conditions. A multi-parameter monitoring prototype integrating infusion volume, drip rate, and heart rate sensors was deployed as an experimental platform. Network performance was evaluated through controlled measurements of RSSI, end-to-end latency, and self-healing behavior, while MQTT was employed to assess cloud-based transmission efficiency. The results demonstrate that ESP-Mesh maintains stable self-healing communication with an average multi-hop latency of 0.714 s across distances up to 5 m, with latency increasing consistently as RSSI decreases. MQTT cloud transmission achieved a lower average latency of 0.247 s with zero packet loss, confirming its suitability for lightweight medical data delivery. Sensor evaluation revealed high accuracy for infusion volume monitoring (95.42%), while heart rate and drip rate measurements exhibited lower reliability due to signal interference and environmental sensitivity. These findings provide empirical insights into the performance limits and trade-offs of ESP-Mesh networks in medical IoT environments. The study confirms the feasibility of ESP-Mesh as a resilient communication backbone for medical monitoring, while highlighting the necessity of advanced signal processing to achieve clinical-grade sensing reliability.

Abstract

This study discusses the implementation of SNMP-based network monitoring with tools such as Cacti, Telegram, and The Dude. A common problem in networks is damage to router interfaces. In this study, notifications of problematic interfaces and bandwidth usage are sent via Telegram. The main objectives of this network monitoring are to monitor network stability, bandwidth usage, remote device monitoring, and to detect problems with interfaces. Cacti is used to monitor and analyze network performance. Telegram plays a role in receiving notifications related to problematic interfaces and bandwidth usage. Meanwhile, The Dude is used to automatically monitor and manage network devices by detecting connected devices. This study uses four routers and one server in i ts implementation. This monitoring focuses on interfaces that manage network distribution and data traffic. The results of this study show that on August 14, 2023, from 14:00 to 17:20, bandwidth measurements from the Cacti and Graphing charts. For inbound traffic, the maximum value on ether1 (CORE) with the Cacti application was 10.27 Mbps and on Graphing it was 11.56 Mbps with a difference of 1.29 Mbps. In comparing the maximum values for inbound traffic, the difference between the data obtained from Cacti and Graphing ranged from only 3.2% to 12.9%. This demonstrates the accuracy of the monitoring tools used in this study.

Abstract

Beberapa klinik medis dan rumah sakit dalam proses pemantauan infus dan detak jantung pada pasien masih mengandalkan pemantauan manual yang dilakukan oleh tenaga medis sehingga berpotensi menyebabkan keterlambatan penanganan pada pasien. Selain itu, infrastruktur jaringan yang kurang memadai pada lingkungan klinik medis atau rumah sakit seringkali menyebabkan kegagalan pengiriman data perangkat monitoring. Penelitian ini bertujuan untuk merancang sebuah sistem monitoring infus dan detak jantung pasien dengan memanfaatkan sensor Load Cell HX711, Infrared dan pulse oximeter. Data hasil pembacaan sensor dikirim menggunakan jaringan ESP-Mesh dan diproses oleh server pusat yang terhubung dengan salah satu node melalui komunikasi serial UART, data kemudian ditampilkan pada sebuah website monitoring. Pengujian sistem dilakukan dengan pengukuran akurasi pembacaan sensor dan analisis kinerja jaringan ESP-Mesh berdasarkan nilai RSSI dan latensi jaringan. Hasil pengujian menunjukkan tingkat akurasi yang bervariasi untuk setiap sensor, dengan Load Cell HX711 mencapai akurasi tertinggi sebesar 95,42%, sensor Pulse Oximeter sebesar 80,64%, dan sensor Infrared sebesar 71,41%. Jaringan ESP-Mesh dapat beroperasi stabil antar node pada jarak hingga 6,2 meter dengan latensi rata-rata 0,714 detik. Sistem ini diharapkan mampu mendukung pemantauan pasien secara real-time dan mengurangi keterlambatan penanganan medis pada pasien.
