Conventional network architectures often fail to meet the demands of high-speed and low-latency communication, especially for applications such as the Internet of Things and cloud computing. This study applies a Kubernetes-based clustering method to address these challenges to optimize 5G network performance through efficient resource allocation and load balancing. Experiments were conducted in a Containerized Network Function environment through simulations, demonstrating significant performance improvements. Test results recorded a 28.69% reduction in latency, a 34.52% increase in throughput, and a 32.14% reduction in packet loss compared to a non-clustered 5G network. These improvements are supported by Kubernetes features such as auto-scaling, traffic distribution, and real-time load balancing. This approach demonstrates that Kubernetes clustering effectively enhances Quality of Service, optimizes resource allocation, and improves the overall efficiency of 5G network systems.</p> <p>Keywords: 5G Networks, Clustering, Kubernetes, QoS, Resource Management</p> Ronald Adrian, R.

Sistem ini dirancang untuk mengatasi masalah penimbangan dari <em>Checkweigher </em>lama yang penimbangannya sering dibawah setpoint, tidak stabil, dan kurang presisi. Pada <em>Checkweigher</em> yang lama mempunyai kelemahan yaitu penimbangannya tidak dapat dipantau secara jarak jauh. Pada <em>Checkweigher</em> yang dirancang ini display dan data penimbangan ditampilkan pada HMI di kontrol lokal dan terhubung ke sistem SCADA untuk pemantauan jarak jauh. Sistem <em>Checkweigher</em> yang dirancang memiliki 5 zona koreksi: <em>Underweight</em>, <em>Tendency</em>(-), normal (setpoint), <em>Tendency</em>(+), dan <em>Overweight</em>, dengan <em>set point</em> 40–40,3 kg. Hasil pengujian menunjukkan <em>Checkweigher</em> bekerja baik, dengan rata-rata error sensor load cell 0,118% dan penimbangan lebih banyak masuk ke zona setpoint. Sistem ini berhasil meminimalisir <em>Underweight</em>, dengan 30,88% penimbangan masuk zona 1 dan 2 (<em>Underweight</em> dan <em>Tendency</em>(-)), serta 69,12% masuk zona 3, 4, dan 5 (normal, <em>Tendency</em>(+), dan <em>Overweight</em>).</p> Dinda Ayu Permatasari, Alfian Raid Jiddan Al Fath, Edi Sulistio Budi, Wahyu Tri Wahono Copyright (c) 2025 Dinda Ayu Permatasari, Alfian Raid Jiddan Al Fath, Edi Sulistio Budi, Wahyu Tri Wahono https://creativecommons.org/licenses/by/4.0 https://journal.isas.or.id/index.php/JASENS/article/view/1140 Sat, 21 Jun 2025 05:18:31 +0100 Peningkatan Akurasi Kontrol Arah Kapal Menggunakan Sensor Kompas BNO055 https://journal.isas.or.id/index.php/JASENS/article/view/1147 <p>The accuracy of a ship's heading measurement is an important element in ensuring the ship moves towards its destination precisely and safely. One of the key parameters in this system is the ship's heading, which indicates the direction of the ship relative to a specific reference point, such as magnetic north. However, heading measurements are often affected by environmental disturbances, magnetic interference and sensor calibration errors, which can degrade measurement accuracy. This research proposes the use of the BNO055 sensor, which combines an accelerometer, gyroscope and magnetometer in a single module to measure ship orientation in three dimensions. An STM32 microcontroller is used to process the data from the BNO055 sensor and calculate the ship's heading and relative bearing with high precision. The calculation results are then displayed on the Nextion Display, providing visual information needed by the user. Test results show that the system provides high accuracy, with an average percentage error of 0.002% for heading and 0.208% for angle. The system can steer the ship with high precision, despite magnetic field disturbances. Thus, this BNO055 and STM32-based system is expected to improve efficiency and accuracy in ship direction measurement applications.</p> Dwi Agus Setiyono, Afif Zuhri Arfianto, Dimas Pristovani Riananda, Agus Khumaidi, Noorman Rinanto, Zindhu Maulana Ahmad Copyright (c) 2025 Dwi Agus Setiyono https://creativecommons.org/licenses/by/4.0 https://journal.isas.or.id/index.php/JASENS/article/view/1147 Mon, 30 Jun 2025 00:00:00 +0100 Integrasi Sistem ESP32 dengan Pemantauan Cuaca Menggunakan Sensor Meteorologi https://journal.isas.or.id/index.php/JASENS/article/view/1149 <p>This study proposes an ESP32-based system integration for real-time weather monitoring using meteorological sensors including wind speed, wind direction, and rainfall sensors. ESP32 is chosen as the main platform because of its capability in wireless communication (Wi-Fi and Bluetooth) and its efficiency in processing sensor data with low power consumption. This system combines meteorological sensors to measure wind speed, wind direction, and rainfall, which are then displayed directly on the Nextion screen. The collected data will be updated in real-time, providing easily accessible information. The purpose of this study is to develop an effective and integrated weather monitoring system. The test results show that this system can collect and display data accurately on Nextion, providing an efficient and practical weather monitoring solution.</p> Yusma'el Khammi Prayoga, Afif Zuhri Arfianto, Dimas Pristovani Riananda, Muhammad Khoirul Hasin, Adianto, Ryan Yudha Adhitya Copyright (c) 2025 Yusma'el Khammi Prayoga, Afif Zuhri Arfianto,ST.MT, Dimas Pristovani Riananda,S.ST.MT https://creativecommons.org/licenses/by/4.0 https://journal.isas.or.id/index.php/JASENS/article/view/1149 Mon, 30 Jun 2025 00:00:00 +0100 Rancang Bangun Sistem Pelacak Posisi Human Indoor Location menggunakan ESP-Now https://journal.isas.or.id/index.php/JASENS/article/view/1150 <p>This research aims to develop an Internet of Things (IoT)-based employee attendance and position tracking system using the ESP-NOW protocol integrated with a web database. This system is designed to automatically record attendance and monitor the position of employees in real-time using the Trilateration method with the Exponential Path Loss model. Data from the ESP32 device is sent to the MySQL database via the MQTT protocol and displayed in an easily accessible website interface. The results show that the system can efficiently recap daily, weekly, and monthly attendance data, as well as display the position history of employees and guests with sufficient accuracy. With the implementation of this system, the efficiency and accuracy of attendance management and employee monitoring at Sutami Hydroelectric Power Plant has increased significantly.</p> <p>&nbsp;</p> Ega Adi Rachmawan, Lilik Subiyanto, Adianto, Mat Syaiin, Aulia Rahma Annisa, Mustika Kurnia Mayangsari Copyright (c) 2025 Ega Adi Rachmawan, Lilik Subiyanto, Adianto, Mat Syaiin, Aulia Rahma Annisa, Mustika Kurnia Mayangsari https://creativecommons.org/licenses/by/4.0 https://journal.isas.or.id/index.php/JASENS/article/view/1150 Mon, 30 Jun 2025 00:00:00 +0100 Sistem Input Output Inventaris Tools Menggunakan Long Range RFID Study Case di PLTA Sutami https://journal.isas.or.id/index.php/JASENS/article/view/1152 <p>The problem faced by Sutami Hydroelectric Power Plant in the management and data collection of tools is that the data collection is still done manually, and some tools are not returned to their place due to negligence in use. To support the achievement of the 5S culture (Seiri, Seiton, Seiso, Seiketsu, Shitsuke) at Sutami Hydroelectric Power Plant, an automated tools management system is needed. In the application of the goods input and output system, many are still using low frequency RFID with a reading range of &gt;5cm so that tapping must be done with an RFID Reader. This still has the potential for an unrecorded loan process if the item is not tapped. This research optimizes the tools management system with long range RFID. With the designed update, it is expected that the tools management system at Sutami Hydroelectric Power Plant can provide increased productivity and also achieve the 5S culture at Sutami Hydroelectric Power Plant.</p> Muhammad Fa'iz, Joko Endrasmono, Sholahuddin Muhammad Irsyad, Lilik Subiyanto, Anggar Juna Puncak Pujiputra, Mustika Kurnia Mayangsari Copyright (c) 2025 Muhammad Fa'iz https://creativecommons.org/licenses/by/4.0 https://journal.isas.or.id/index.php/JASENS/article/view/1152 Mon, 30 Jun 2025 00:00:00 +0100
