Vibrasi pada helikopter menjadi konsentrasi tersendiri untuk terus ditingkatkan penanganannya. Hal ini dikarenakan selain dapat menyebabkan kerusakan struktur badan helikopter jika vibrasi yang dihasilkan terlalu besar juga berpengaruh pada kenyamanan pilot dan penumpang. Sistem vibrasi pada helicopter terdiri dari baling-baling, rotor mount, dan suspensi dimana terdapat damper sebagai peredam. Pada penelitian ini, digunakan damper semi aktif yang variabelnya dikontrol dengan menggunakan kontrol adaptif L1 berbasis analisis Fourier dari vibrasi yang dihasilkan oleh rotor. Analisis Fourier digunakan untuk mencari frekuensi cutoff vibrasi yang digunakan untuk penalaan pada kontrol adaptif L1. Hasil rancangan band pass filter orde 2 pada sistem dapat memperbaiki respon percepatan hingga 72.52% pada rotor mount dan 65.94% badan helicopter dalam waktu 2 detik. Hasil rancangan juga dapat menangani kesalahan perpindahan sebesar 55.6% pada rotor mount dan 55.56% pada badan helikopter dalam waktu 2 detik. Perbaikan respon percepatan pada badan helicopter yang mencapai 0 m/s2 telah memenuhi rekomendasi NASA untuk minimal percepatan pada sistem vibrasi helikopter. ABSTRACT Vibration in helicopters is a separate concentration to continue to improve its handling. This is because, in addition to causing damage to the helicopter body structure if the vibration generated are too large, it also affects the comfort of pilot and passengers. The vibration system on the helicopter consists of propeller, rotor mount, and suspension where there are dampers as dampers. In this research, a semi-active damper is used whose variables are controlled using Fourier analysis-based L1 adaptive control of the vibrations generated by the rotor. Fourier analysis is used to find the cutoff frequency of vibration used for tuning the L1 adaptive control. The results of the second-order band pass filter design in the system can improve the acceleration response up to 72.52% on the rotor mount and 65.94% of the helicopter body within 2 seconds. The design results can also handle displacement errors of 55.6% on the rotor mount and 55.56% on the helicopter body within 2 seconds. The improvement of the acceleration response on the helicopter body which reaches 0 m/s2 has required NASA's recommendations for minimum acceleration in helicopter vibration systems.

This study focuses on the implementation of the YOLOv4-Tiny algorithm on Raspberry Pi 5 for detecting plastic bottle waste in aquatic environments. The primary goal is to optimize the frame per second (FPS) while maintaining detection accuracy. A dataset consisting of 914 images was augmented using RoboFlow to enhance the robustness of the model under real-world conditions. Experiments were conducted in a controlled pool environment with an input resolution of 320x320 pixels. Results demonstrated an average FPS of 7-8, with detection accuracy ranging between 67% and 80%. Further evaluation reported a total loss of 0.3, mean Average Precision (mAP) of 97.94%, precision of 93%, recall of 96%, F1 score of 0.95, and an average Intersection over Union (IoU) of 76.47%, indicating effective bounding[1] box prediction capabilities. These results highlight the potential of YOLOv4-Tiny as a lightweight and real-time detection solution, particularly for low-computational devices such as Raspberry Pi. The findings provide a solid foundation for developing efficient plastic waste detection systems, which can be deployed across various aquatic locations, supporting environmental monitoring and waste management initiatives.

Seorang kiper (penjaga gawang) mempunyai tugas yang sangat krusial dikarenakan seorang kiper bertugas untuk menjaga gawangnya agar tidak kemasukan gol. Beberapa peneliti telah melakukan penelitian dan pengembangan terhadap metode pelatihan kiper hingga menghasilkan sebuah alat bernama ball launcher. Penelitian dan pengembangan ball launcher atau alat pelontar bola yang telah dilakukan ini mempunyai sistem yang kurang efisisen. Pada saat akan menembakkan atau melontarkan bola ke kiper, pengaturan arah dan kecepatan alat masih dilakukan secara manual. dan pada saat akan menembakkan bola lagi harus memasukkan bola secara manual. Pada penelitian ini akan dikembangkan menjadi mobile robot dan ditambahkan fitur berupa pengotomatisan pengaturan kendali arah dan kecepatan pada launcher atau pelontar. Pengatruran kecepatan pelontar menggunakan metode pwm dan sistem kontrol arah pelontar menggunakan feedback dari sensor. Hasil akhir dari penelitian ini adalah rancangan desain sistem kendali kecepatan dan arah pelontar pada mobile robot pelempar bola telah berhasil dirancang dan diimplementasikan dengan sukses. Sistem ini mampu melakukan pelontaran bola dengan kecepatan maksimum 70 km/h dan dengan tingkat kepresisian yang tinggi sesuai dengan arah yang dituju, serta dapat mengatur kecepatan pelontaran dalam tiga mode yang berbeda. Uji coba terhadap sasaran gawang juga menghasilkan data yang menunjukkan keberhasilan bola mencapai sembilan titik pada gawang yang telah ditentukan sebelumnya dengan hasil 67 pelontaran tepat target dan 4 tidak sesuai target. Dapat disimpulkan bahwa implementasi keseluruhan sistem kendali kecepatan dan arah pelontar pada mobile robot pelempar bola telah memberikan hasil yang memuaskan dan mencapai tujuan yang telah ditetapkan. Kata kunci— sepak bola, kendali arah, kendali kecepatan, ball launcher.

This system uses the PZEM-004T sensor module as a measuring instrument for electrical parameters combined with Internet of Things (IoT) technology, and an initial study of BACnet communication integration as an additional protocol. The research includes a literature study related to the basic concepts of electric power monitoring, Modbus and BACnet communication protocols, and IoT technology. System design involves the integration of hardware and software with an IoT-based user interface to support data acquisition and visualization. The collected data is sent via MQTT communication to the cloud and displayed in graphical form via the Node-RED platform, allowing real-time monitoring of electric power consumption with an interactive and customizable dashboard display. The test results show that the system is able to record data in real-time and present accurate information, so that it can be the basis for making energy management decisions.

The increasing presence of inorganic waste such as plastic bottles and cans poses a serious environmental threat and demands efficient detection solutions. This study aims to develop a real-time detection and position estimation system for inorganic waste using the YOLO v4-Tiny algorithm combined with homography transformation. A total of 3,388 labeled images were prepared and augmented via the Roboflow platform. The detection model was trained using the Darknet framework, while homography was applied to estimate object positions in real-world coordinates. System performance was evaluated based on precision, recall, F1-score, mean Average Precision (mAP), and Intersection over Union (IoU). The results show a mAP of 86.43%, precision of 77%, recall of 90%, and an average IoU of 62.33%. The system achieved a frame rate of 3–5 FPS, demonstrating its potential for low-power embedded devices. This approach is suitable for real-time waste monitoring using computer vision in constrained environments.
