Abstract

Transportasi termasuk bagian penting untuk menunjang berbagai kegiatan di sebuah kota, termasuk di Indonesia. Hal ini dikarenakan hampir semua kegiatan manusia tidak lepas dari proses transportasi, baik dari segi perpindahan orang maupun perpindahan barang. Transportasi barang (logistik) di Indonesia masih didominasi oleh angkutan jalan, khususnya dengan menggunakan truk. Namun, banyak ditemukan pengguna truk dengan muatan yang berlebih. Hal itu sangat membahayakan pengguna truk itu sendiri dan membahayakan pengguna jalan yang lain. Selain dari itu, truk dengan muatan yang berlebih akan menyebabkan kerusakan jalan. Maka dari itu dibuatlah sistem monitoring berat muatan truk, sistem ini bekerja dengan cara mengukur berat muatan pada truk dengan menggunakan sensor loadcell dan data yang sudah didapat akan ditampilkan pada website. Kata Kunci : loadcell, website, transportasi.

Abstract

Public Dental health must be maintained from an early age. However, it is not easy to make the children interested, understand, and aware of dental health. This paper discussed alternative methods for educating the children using IRVO model in augmented reality technology-based educational games. The game was built from several materials consisting of dental health education recommended by the dentist. Some of the interactions represented in the game application consist of point of view, selection and release, event creation, and manipulation. This educational game is implemented using the 3DS Max and D-Fusion Studio. This game has been approved for counsellors such as dentists, nurses, community health workers, and children. According to the resulting test, more than 75% of the dentists and children are interested in using this game and declared that they could use this application easily.

Abstract

Buses are the most used transportation by people in Indonesia when traveling between cities. However, to improve passenger comfort, a tool is required to determine the number of passengers on the bus. This research presents an automated system to count the number of passengers based on a background subtraction algorithm and moving object activator.  This research aims to provide the number of passengers based on video images taken from the entranceway. The system is built with a camera, Raspberry Pi, and LCD. The APC system starts the counting process by removing the video background image from the captured object image. The entry and exit direction of the object is determined using the concept of moving object activator. The experiments were applied in several scenarios to determine the robustness of the system. The best APC performance was achieved when the system is positioned perpendicularly above the entranceway at a height of 230 cm and a light intensity of 800-1000 lux. Meanwhile, the moving object activator is effective in supporting the system's performance to determine the passenger's direction. In this scenario, the results stated that the accuracy of APC system performance reached 93.8%.

Abstract

In UWB-based indoor positioning, it is important to observe the ranging performance of the UWB module to prevent positioning errors. Ranging is the initial process in computing positioning. This research aims to observe the ranging accuracy and precision of the ESP32 UWB Pro with a Display module and analyze its performance in indoor positioning using TDoA and Trilateration. The ranging method was held using the SS-TWR which is the basic ranging used generally in UWB. ESP32 Pro is a module consisting of ESP32 and OLED display which is integrated with Decawave DW 1000. Analysis of 6750 ranging error data is carried out to determine the appropriate method to increase accuracy. The convergence of error ranges that occur leads to the use of regression as an error mitigation method for Decawave on the ESP32 UWB Pro with Display module. Increasing the accuracy of ranging regression can reduce the error from MAE of 79.98cm to only 5.05cm. It’s applied to positioning to obtain the accuracy and precision performance of the TDoA and Trilateration positioning.  The resulting MAE values are 7.47cm for X and 10.49cm for Y in TDoA Positioning. Meanwhile, in Trilateration, the MAE was 8.15cm for X and 8.47cm for Y. Our findings indicate that an increase in ranging accuracy with regression had an impact on positioning accuracy. However, the spread of error positioning shows that it’s still weak in precision.

Abstract

Indoor positioning plays a crucial role in various applications, including smart homes, healthcare, robotics, and asset tracking. However, achieving high positioning accuracy in indoor environments remains a significant challenge due to obstacles that introduce NLOS conditions and multipath effects. These conditions cause signal attenuation, reflection, and interference, leading to decreased localization precision. This research addresses these challenges by optimizing feature selection LOS, NLOS, and multipath classification within Ultra-Wideband (UWB) ranging systems. A systematic feature selection approach based on Pearson correlation is employed to identify the most relevant features from an open-source dataset, ensuring efficient classification while minimizing computational complexity. The selected features are used to train multiple machine-learning classifiers, including Random Forest, Ridge Classifier, Gradient Boosting, K-Nearest Neighbor, and Logistic Regression. Experimental results demonstrate that the proposed feature selection method significantly reduces model training and testing times without compromising accuracy. The Random Forest and Gradient Boosting models exhibit superior performance, maintaining classification accuracy above 90%. The reduction in computational overhead makes the proposed approach highly suitable for real-time applications, particularly in edge-computing environments where processing efficiency is critical. These findings highlight the effectiveness of Pearson correlation-based feature selection in improving UWB-based indoor positioning systems. The optimized feature set facilitates robust LOS, NLOS, and multipath classification while reducing resource consumption, making it a promising solution for scalable and real-time indoor localization applications.

Abstract

Today wireless technology grows rapidly, especially in the field of telecommunications and communications. Computer networks now widely utilizes wireless. Wireless Mesh Network is one of the method which is use to communicate computer wirelessly. One important factor in application of wireless network is how to extend wireless signal coverage. Wireless Distribution System is one way to expand the wireless network by mean of wireless interconnection of access point on the network IEEE 8022.11. This study suggests how to build a simple wireless computer network using WDS technology and describes connectivity performance and its signal coverage. The test result of connectivity performance shows that the connectivity between two computers work properly for reliability and multi SSID testing. However, the connectivity was not success in multichannel testing. Furthermore the test result of coverage shows that the range of wireless signal coverage reaches 39 meters with different circumstance room.
