Abstract

Efficient energy management in Internet of Things (IoT) devices is critical in dynamic, resource-constrained operational environments. This study proposes the Queen Honey Bee Migration (QHBM) optimization algorithm for managing Li-ion battery performance in IoT systems, employing the Shepherd battery model to simulate the nonlinear discharge behavior under varying load conditions. Three simulation scenarios of increasing complexity (5, 10, and 20 monitoring points) are used to represent urban operational dynamics. The performance of QHBM is quantitatively compared with four conventional optimization algorithms seperti Particle Swarm Optimization (PSO), Differential Evolution (DE), Genetic Algorithm (GA), and Firefly Algorithm (FA). Results show that QHBM maintains a current range of 3.80–5.20 A and a voltage range of 3.65–3.95 V, with State of Charge (SoC) predictions between 75–98%. It also achieves the fastest computation time (0.42–1.20 seconds) and demonstrates more stable performance under high-load dynamic scenarios compared to the other methods. This approach provides an adaptive and efficient optimization framework to support energy-aware decision-making in IoT systems operating in energy-constrained urban environments.

Abstract

One of the most critical components of hostage rescue efforts is the agreement on hostage release. Officer errors in taking action during the negotiation process can jeopardize the safety of personnel and officers as well as hostage victims. Lack of communication often leads to dangerous conflicts that can hamper hostage taking. To solve this problem, we designed a specialized negotiation robot that is armed to ensure the safety and security of officers in the line of duty, both in war situations and hostage release operations. By having weapons, officers responsible for the safety of victims can perform their duties without compromising their personal security. These military robots enable negotiation and monitoring without threatening lives, providing a more efficient and safe approach. In addition, the robot's ability to operate autonomously with the help of artificial intelligence allows for faster assessment of the situation and a more appropriate response, thereby increasing the chances of a successful rescue mission without adding risk to the humans involved. The robot is also equipped with advanced sensors and machine learning algorithms that can detect changes in the hostage-taker's behavior and body language, providing valuable information to the negotiation team to devise a more effective strategy. Thus, the implementation of this technology not only improves the security and efficiency of military operations, but also paves the way for further innovations in the use of robotics and Artificial Intelligence in various aspects of defense and security.

Abstract

In the process of munitions disposal, there are sometimes challenges that can pose risks to personnel or damage equipment. To address this, a smart relay system was developed with the aim of creating and testing a detonation control system to support munitions disposal in military operations. This research used an experimental approach, where the system was tested at various distances and environmental conditions. The testing aimed to measure response speed, relay activation success rate, and signal range. The results showed that the **smart relay** system was capable of operating with a fast response time up to a distance of 250 meters, with a success rate of 98% in the laboratory and 96% in outdoor conditions. However, the system still faces challenges in terms of signal range and battery life, especially at distances over 400 meters or in extreme environmental conditions. In conclusion, this control system is effective and efficient in enhancing the safety of munitions disposal. However, further development is needed to extend the signal range and optimize battery life. It is recommended to integrate stronger communication technology and more efficient batteries to improve the system's stability and performance in the field.

Abstract

Pada awal tahun 2020 di Indonesia digemparkan dengan adanya wabah virus yang disebut covid-19. Virus inimenyerang manusia ditandai dengan gejala umum seperti demam, batuk, sesak nafas, paru-paru, dan usialanjut. Badan kesehatan dunia WHO menerapkan protokol yang dapat mencegah penularan virus covid-19salah satunya yaitu physical distancing dan menjaga kontak fisik secara langsung. Pada penelitian inimengunakan metode jaringan saraf tiruan backpropagation digunakan untuk aplikasi pengenalan wajah.Pendeteksian suhu tubuh otomatis menggunakan thermo gun dan melakukan tracking wajah terhadap orangyang memasuki bilik pemeriksaan. Kemudian data dikirim kedalam raspberry pi untuk mematchingkandengan database yang tersedia. Data akan ditampilkan pada layar android dengan klasifikasi yaitu suhu tubuhrendah (hipotermia), normal dan suhu tubuh tinggi (Hipertermia). Terdapat peringatan bila suhu tubuh tinggidengan suara yang dihasilkan oleh buzzer. Alat ini diharapkan mampu memberikan dampak positif sertamembantu pemerintah dalam penanganan dan pencegahan penyebaran covid-19.

Abstract

Krisis energi saat ini merupakan masalah yang sangat mengganggu keberlangsungan hidup manusia,khususnya masalah energi listrik. Pemanfaatan energi listrik tidak hanya dibutuhkan pada bidang industri,bidang transportasi, atau bidang kesehatan tetapi juga dibutuhkan oleh bidang pertahanan dan keamanan. Alatutama sistem persenjataan untuk membantu tugas TNI dan mengantisipasi kerugian personel dalam medanpertempuran. Smart Charging with Stepper merupakan generator mini portable berskala kecil menggunakanmotor stepper yang dipasang pada sepatu PDL TNI guna menghasilkan energi listrik yang selalu kontinuitas.Energi listrik dihasilkan dari gerakan langkah kaki ketika berjalan atau berlari. Ketika telapak kaki menyentuhtanah maka plat besi akan tertekan ke bawah kemudian menggerakkan lengan yang terhubung ke motorstepper kemudian di teruskan menuju rangkaian smart charging system pada Rompi. Energi listrik tersebutdisearahkan oleh diode bridge, kemudian masuk ke kapasitor sebagai penyimpanan sementara. Sebelumenergi listrik masuk ke power storage atau baterai, energi listrik tersebut akan distabilkan oleh rangkaiancharging sesuai dengan set point yang telah ditentukan. Data arus dan tegangan yang diperoleh dari sensorarus dan tegangan akan diolah oleh mikrokontroler yang kemudian akan ditampilkan pada Oled. Dengan satukali melangkah maka motor akan berputar bolak balik 180?, sehingga menghasilkan total tegangan tanpa bebansebesar 14,2 V dan total tegangan dengan beban 2 K? sebesar 7,62 V. Total arus yang dihasilkan denganbeban 2 K? sebesar 0,4018 A, sehingga mengasilkan Daya sebesar 3,0617 W. Penggunaan Smart Chargingwith Stepper ini merupakan suatu inovasi di bidang energi alternative guna membantu mangatasi krisis energilistrik di daerah perbatasan. Sehingga mampu mengoptimalkan kinerja TNI AD dalam pengamanan di daerahperbatasan
