Digital interactions are still commonly using indirect media such as mouse and keyboard to provide user input in the form of two-dimensional data. Therefore, to provide intuition in virtual interactions, it is possible to add media that can draw directly in the air or a flat surface that will track hand movements and overall finger position. In this research, we try to track hand movements in real time by capturing the position of the hand and finger curvature using a wearable sensor equipped with an Inertial Measurement Unit (IMU) sensor and a flex sensor installed by the user. Then the system will identify the position of the user's finger bending. and the location indicated by the sensors installed to move the cursor on the screen and simulate left-click and right-click hand movements as with a traditional mouse. By using this system, users can interact with the computer more naturally and get the accuracy of cursor movement with the accuracy of finger movement translation reaching more than 85% and the translation of hand movements to mouse cursor movements is on average 73% for shapes that use straight lines. and 23.4% on curved lines such as circles and other shapes.

This research aims to develop and implement an electrical power monitoring system at the Sub Sub Distribution Panel (SSDP) in the Building. The system is designed to monitor power usage in real-time, provide accurate information on energy consumption, and detect potential energy waste. The methodology used includes hardware and software design. The hardware consists of current and voltage sensors connected to a microcontroller. The data collected by the sensors is then transmitted via Wi-Fi network to the server for analysis. The software uses an Internet of Things (IoT) platform that displays the data in the form of graphs and tables. The implementation shows that the system is capable of monitoring power usage with a high degree of accuracy. The sensors used, namely PM2100 for voltage, SHT20 for temperature and humidity, and GP2Y101AU0F for dust concentration, proved effective in generating accurate real-time data. Based on the test results, the voltage measurement error with the PM2100 was only 0.035%, while the current measurement resulted in an error of 0.48%. The SHT20 sensor recorded an error of 2.4% for temperature and 1.0% for humidity. Dust measurements with the GP2Y101AU0F sensor had a very small error of 0.02%. These results indicate that the tested device has a sufficient level of precision for electrical power and environmental monitoring applications.

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 >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.

Setiap sistem kelistrikan bergantung pada ketersediaan energi yang berkelanjutan untuk menjaga produktivitas industri tetap berjalan. Gangguan listrik akan merusak peralatan listrik. Sistem proteksi berfungsi untuk meminimalkan hingga menghilangkan gangguan secara cepat, selektif, dan terkoordinasi demi meminimalkan kerusakan sistem dan memastikan pasokan listrik yang tidak terputus. Khususnya untuk rele arus lebih, time dial setting (TDS) merupakan aspek penting yang harus dipertimbangkan perihal koordinasi proteksi. TDS mengatur waktu operasi rele untuk mengamankan sistem kelistrikan. Umumnya, perhitungan manual digunakan untuk menentukan nilai TDS. Metode trial and error sering digunakan untuk mengoordinasikan rele satu sama lain. Metode ini telah berkembang menjadi algoritma cerdas yang dapat menemukan solusi secara efektif dan cepat, salah satu algoritmanya adalah grasshopper optimization algorithm (GOA). Hasil dari simulasi pada penelitian ini didapatkan nilai koordinasi antara rele 4 bekerja pada 0,1 detik & rele 3 bekerja pada 0,3 detik saat timbul gangguan pada trafo 2, rele 3 bekerja pada 0,297 detik & rele 2 bekerja pada 0,496 detik saat timbul arus gangguan pada bus 4, rele 2 bekerja pada 0,492 detik & rele 1 bekerja pada 0,493 saat timbul arus gangguan pada bus 3 serta kinerja rele 1 yang hanya sebagai primer untuk mengamankan generator bekerja pada 0,354 detik saat timbul arus gangguan pada bus 2 telah menghasilkan nilai perhitungan TDS yang akurat serta masih mematuhi aturan pengaturan minimum nilai coordination time interval (CTI) antara rele primer dan rele backup yaitu 0,2 detik dalam satu rating tegangan dan mendekati 0 di rating tegangan yang berbeda.

This study proposes a Color Threshold-based object detection and calibration system using an Orbbec Astra Pro Plus Stereo Vision camera on a wheeled soccer robot (KRSBI-B) to improve the accuracy and efficiency of real-time ball detection. The camera calibration process is performed using the built-in automatic feature of the Orbbec Astra OpenNI SDK, without manual calibration. Validation results show that the camera depth system has a high level of accuracy with a maximum error of 2% at a distance of 50 cm and an average error of 1.73%, making it suitable for use in object distance estimation. The HSV (Hue, Saturation, Value)-based Color Threshold method was calibrated interactively using color sliders with an optimal range of Hue (5–20°), Saturation (120–255), and Value (100–255). Testing was conducted under synthetic lighting conditions of 500 lux with a distance variation of 50–300 cm. The best results were obtained at a distance of 250 cm, with 0% measurement error and full detection on binary images. The system also showed high stability at distances of 100–300 cm with an average error of only 0.63%, while objects were not detected at a distance of 50 cm due to the camera's field of view limit. This approach provides high processing speed, good detection stability, and low computational load compared to deep learning-based methods. The integration of stereo calibration and the HSV method results in an efficient, accurate, and adaptive vision system, making it highly suitable for real-time applications on wheeled soccer robots.

Robot sepak bola beroda memerlukan sistem navigasi yang akurat agar dapat bergerak sesuai lintasan yang direncanakan. Tanpa sistem navigasi yang presisi, robot berpotensi mengalami penyimpangan lintasan yang dapat menurunkan efektivitas permainan. Salah satu metode yang umum digunakan untuk memperkirakan posisi dan orientasi robot adalah odometry berbasis sensor rotary encoder, yang menghitung posisi relatif berdasarkan akumulasi pulsa dari putaran roda. Penelitian ini bertujuan untuk mengimplementasikan rotary encoder sebagai sensor utama dalam sistem odometry guna meningkatkan akurasi estimasi posisi dan orientasi pada robot sepak bola beroda. Tiga buah rotary encoder dipasang pada roda omni-directional dengan konfigurasi sudut 120°, diintegrasikan dengan mikrokontroler STM32F407 untuk pembacaan pulsa, perhitungan keliling roda, serta transformasi koordinat kartesian menggunakan persamaan kinematika omni-directional. Hasil pengujian menunjukkan bahwa sistem odometry berbasis rotary encoder mampu memperkirakan jarak tempuh dengan rata-rata error antara 2,00% hingga 2,33%, lebih baik dibandingkan sistem tanpa odometry yang mencapai error hingga 15%. Dengan demikian, penggunaan rotary encoder terbukti efektif dalam meningkatkan akurasi navigasi robot sepak bola beroda dan dapat dijadikan dasar untuk pengembangan sistem navigasi yang lebih kompleks.
