Abstract

This study examines how variations in Maximum Transmission Unit (MTU) affect network performance in a Software-Defined Networking (SDN) architecture using the Ryu controller, Mininet, and Open vSwitch. Experiments were conducted in a virtualized Ubuntu 18.04 environment with four MTU settings 500, 1000, 1500, and 2000 bytes and performance was evaluated through repeated measurements of Round Trip Time (RTT), throughput, jitter, and packet loss. All scenarios produced 0% packet loss, enabling focused analysis on latency, efficiency, and temporal stability. The results indicate that MTU size has a non-linear influence on SDN behavior. The 1000-byte MTU yielded the lowest RTT (10.9 ms), while larger and smaller values introduced higher delay. Throughput peaked at 1500 bytes (11.4 Mbps) but declined sharply at 2000 bytes, reflecting inefficiencies in processing oversized packets. Jitter showed a distinct pattern, remaining low at 500 bytes, increasing at mid-range MTUs, and decreasing again at 2000 bytes, suggesting sensitivity to internal buffering and queue dynamics. Overall, MTU values between 1000 and 1500 bytes offer the most balanced performance across latency, throughput, and jitter. These findings highlight the need for careful MTU selection to optimize the operational stability and efficiency of SDN-based networks.

Abstract

Pemilihan laptop berdasarkan spesifikasi merupakan permasalahan pengambilan keputusan yang melibatkan banyak kriteria, seperti harga, kapasitas RAM, kapasitas penyimpanan (ROM), berat perangkat, dan jenis prosesor. Banyaknya alternatif laptop dengan spesifikasi yang beragam menyebabkan proses pemilihan menjadi kurang efektif apabila dilakukan secara manual. Oleh karena itu, diperlukan suatu sistem pendukung keputusan yang mampu membantu proses pemilihan laptop secara objektif dan terstruktur. Penelitian ini bertujuan untuk mengimplementasikan metode Fuzzy Tahani pada sistem pendukung keputusan pemilihan laptop berdasarkan spesifikasi. Metode Fuzzy Tahani digunakan untuk mengolah data spesifikasi laptop yang bersifat tegas (crisp) ke dalam bentuk derajat keanggotaan fuzzy. Proses pengambilan keputusan dilakukan melalui pemeringkatan alternatif dengan mengombinasikan beberapa kriteria menggunakan operator logika AND dan OR untuk memperoleh tingkat kecocokan masing-masing alternatif. Hasil penelitian menunjukkan bahwa metode Fuzzy Tahani mampu menghasilkan pemeringkatan alternatif laptop berdasarkan tingkat kecocokan terhadap kriteria yang ditetapkan. Berdasarkan hasil pemeringkatan tersebut, alternatif laptop dengan nilai kecocokan tertinggi ditetapkan sebagai rekomendasi, yaitu ASUS ZenBook Q408UG. Hasil ini menunjukkan bahwa metode Fuzzy Tahani efektif digunakan dalam mendukung proses pengambilan keputusan pemilihan laptop. Kata Kunci: Fuzzy Tahani; logika fuzzy; pemeringkatan alternatif; pemilihan laptop; sistem pendukung keputusan

Abstract

Kebakaran merupakan salah satu bencana yang sering terjadi di lingkungan rumah tangga dan ruang tertutup, yang umumnya diawali oleh kebocoran gas mudah terbakar. Salah satu permasalahan pada sistem deteksi gas adalah ketidakstabilan pembacaan sensor akibat noise dan pengaruh lingkungan. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem penanggulangan kebakaran berbasis Internet of Things (IoT) dengan meningkatkan kestabilan pembacaan sensor MQ-2 menggunakan algoritma Kalman Filter. Sistem dikembangkan menggunakan sensor MQ-2 sebagai pendeteksi gas, mikrokontroler ESP32 sebagai unit pemrosesan, serta LCD dan platform IoT sebagai media monitoring. Kalman Filter diterapkan pada data pembacaan sensor untuk mereduksi fluktuasi dan noise sebelum digunakan sebagai dasar pengambilan keputusan. Hasil pengujian menunjukkan bahwa pembacaan sensor yang telah diproses menggunakan Kalman Filter memiliki pola yang lebih stabil dan halus dibandingkan data mentah. Selain itu, sistem mampu menampilkan kondisi lingkungan secara konsisten pada LCD dan platform IoT Blynk, baik pada kondisi aman maupun saat terdeteksinya gas. Dengan demikian, sistem yang dikembangkan dinilai layak digunakan sebagai sistem peringatan dini dan penanggulangan kebakaran berbasis IoT.

Abstract

Continuous monitoring of radiation exposure and environmental conditions is essential to ensure safety and operational efficiency in X-ray laboratories. However, commercially available systems are often expensive and less adaptable to smaller facilities. This study proposes the design and performance evaluation of a low-cost, Arduino-based integrated monitoring device for X-ray laboratory conditions. The system integrates a Geiger–Müller detector for radiation counting with environmental sensors for temperature, humidity, and light intensity (DHT11 and BH1750). Experimental testing was conducted to evaluate the accuracy of the timer, sensor performance, and radiation counting capabilities using background radiation and a Cs-137 source. The results demonstrate that the system operates reliably, with deviations in timer counting below 1%, acceptable sensor accuracy, and consistent radiation count rates between detectors. The prototype is capable of real-time data display via a serial monitor and an OLED 1306 screen. This study demonstrates that the proposed system provides an affordable and effective solution for laboratory radiation and environmental monitoring.

Abstract

The increasing capacity of solar power plants connected to the electric distribution network can cause disruptions to the operation of the electric distribution network. Therefore, the maximum capacity of PLTS installed on the electric distribution network or PV hosting must be evaluated and determined. This paper aims to determine the maximum capacity and optimal location of PV hosting on the electric distribution network with a case study on the Patin feeder at the Metro Substation. The operational limitations used in the evaluation of determining the maximum capacity of PV hosting include line overloading, overvoltage on the bus, overloading of the power transformer and reverse active power to the power transformer. The optimal location is the bus where the PV hosting with the maximum capacity is placed which results in the minimum power losses. Determination of the maximum capacity and optimal location of PV hosting on the Patin feeder was carried out by simulation using MATLAB software. The simulation results show that the maximum capacity of PV hosting on each bus in the Patin feeder ranges from 0.093-3.078 MW. Most of the maximum capacity values ​​of PV hosting on each bus are obtained by achieving violations of the reverse active power constraints. The optimal location for PV hosting placement is on bus 10 with an active power loss of 7.51 kW..

Abstract

Software-Defined Networking (SDN) provides centralised network management but introduces a critical structural vulnerability because the controller is highly susceptible to Distributed Denial of Service (DDoS) attacks. While Machine Learning is widely utilised for Intrusion Detection Systems, traditional monolithic models often operate as opaque black boxes, rely on easily spoofed categorical features, and ignore the severe computational latency limits of centralised controllers. This paper proposes a novel, hardware-constrained Feature-Slicing Ensemble architecture for DDoS detection. We partition network data into two domain-specific subsets, namely Header Features and Flow Statistics, while deliberately excluding evasion-prone identifiers to prevent data leakage. Specialised, depth-constrained Random Forest base learners are trained on each subset to simulate controller CPU limitations, with predictions aggregated using a soft-voting mechanism. Evaluated on the InSDN dataset using 5-fold stratified cross-validation, our proposed model achieved an F1-Score of 0.9954. While maintaining strict statistical parity with unconstrained monolithic baselines, the decoupled architecture provides critical explainability, allowing network administrators to isolate structural anomalies from volumetric floods. This demonstrates that logical feature partitioning improves model modularity and real-world evasion resilience without sacrificing predictive precision.

Abstract

Abstract. Electrical energy usage in buildings with three-phase distribution systems requires proper monitoring to ensure energy consumption can be controlled effectively and efficiently. Common problems in building electrical systems include load imbalance between phases, delayed fault detection, and manual monitoring processes that prevent real-time observation of power consumption conditions. This study aims to design and develop an Internet of Things (IoT)-based electrical power consumption monitoring system for the PENMARU Building of Muhammadiyah University of Lampung using the PZEM-004T sensor and ESP32 microcontroller. The system was designed to monitor electrical parameters such as voltage, current, active power, electrical energy, and power factor in a three-phase electrical system in real-time through an IoT-based monitoring dashboard. The research method used in this study was Research and Development (R&D), which included system design, hardware and software implementation, system testing, and analysis of measurement results. The results showed that the system was able to monitor electrical parameters in real-time with a measurement error below 1%. The seven-day testing results indicated that the average power on phase R was 74.86 W, phase S was 225.64 W, and phase T was 51.01 W, with total electrical energy consumption reaching 47.06 kWh. In addition, the system successfully transmitted monitoring data stably through a Wi-Fi network and displayed the data on the IoT dashboard in real-time. Therefore, the proposed monitoring system is considered capable of supporting more effective, responsive, and efficient electrical energy consumption monitoring.
