Abstract

The increasing contribution of the transportation sector to global emissions has driven the development of hybrid electric vehicles (HEVs) as a practical solution to reduce environmental impact. The effectiveness of HEVs is highly dependent on electronic control systems that regulate power distribution between the internal combustion engine (ICE), electric motor, generator, and battery in real time under various operating conditions. This study aims to evaluate the performance of the electronic control system implemented using Stateflow in a simulated series-parallel hybrid electric vehicle. The research methodology involves simulating the vehicle model in MATLAB/Simulink, which integrates Stateflow to design and manage the logic and operational mode transitions. A continuous closed-loop feedback structure is used to facilitate real-time control decisions, guided by input variables such as throttle position, vehicle speed, and battery State of Charge (SoC). Various driving scenarios are simulated, including acceleration, steady cruising, deceleration, and energy recovery during braking. Simulation results show that the designed electronic control system can maintain operational stability with engine efficiency reaching 92%, battery power utilization up to 65%, and electronic transitions between modes (EV, HEV, regenerative) in less than 0.2 seconds, demonstrating a 40% improvement in response compared to conventional electronic control models. These findings confirm the potential of Stateflow-based electronic control approaches in creating more responsive and efficient hybrid vehicle propulsion systems, while supporting the development of low-emission transportation technology

Abstract

Kemajuan teknologi Internet of Things (IoT) telah mendorong penerapan otomatisasi dalam berbagai bidang, salah satunya adalah sistem pemantauan proses penetasan telur. Penelitian ini bertujuan untuk mengevaluasi kualitas layanan jaringan pada sistem monitoring berbasis IoT dengan menggunakan pendekatan Quality of Service (QoS) melalui perangkat lunak Wireshark. Evaluasi dilakukan dengan mengukur empat parameter utama, yaitu throughput, delay, jitter, dan packet loss. Berdasarkan hasil pengujian, nilai rata-rata throughput yang diperoleh sebesar 7,88 Kbps, dengan rentang nilai antara 2,89 Kbps hingga 21,41 Kbps. Parameter delay menunjukkan nilai rata-rata sebesar 67,71 ms, di mana nilai terendah mencapai 2,72 ms dan tertinggi 160 ms, masih dalam kategori sangat baik menurut standar TIPHON. Untuk jitter, nilai rata-rata tercatat sebesar 1,63 ms, dengan variasi dari 0,2 ms hingga 3,0 ms, yang menandakan kestabilan jaringan dalam hal waktu tunda. Adapun packet loss tercatat sebesar 0% pada seluruh pengujian, menunjukkan tidak adanya kehilangan paket data selama transmisi berlangsung. Temuan ini menunjukkan bahwa sistem monitoring IoT yang diuji memiliki kualitas jaringan yang cukup andal dan stabil, serta layak digunakan untuk pemantauan suhu dan kelembaban secara real-time dalam aplikasi inkubasi telur.
