Abstract

East Nusa Tenggara Province is one of the tourist destination areas, one of its prima donnas is Komodo Island which was included in the list of The New 7 Wonders of Nature in 2012. But not only that, there are still many stunning tourist destinations. Kupang City is the main destination before accessing the natural beauty of the East Nusa Tenggara region. In the Kupang City and the Regency of Kupang itself holds many tourist destinations, but the terms of promotion that are still catalog and social media are deemed inadequate. High cost of catalog production and data costs for accessing social media are not cheap either. But by using a router and access point, it is expected that these costs can be eliminated. The router is used to create a hotspot login page. The login page can be modified into a digital catalog (website page) while the Access Point is used to distribute catalog. Hotspots can be accessed free of charge by tourist attractions. Digital catalog can be changed according to the development of tourist attractions. This digital catalog also provides alternative tourism in the Kupang City and other areas in East Nusa Tenggara Province

Abstract

Motorcycles with automatic systems are currently the type of vehicle that are most interested by many riders because they are economical and comfortable. Automatic motorcycles, which are more fuel efficient, seem to be the most desired vehicle by the community today, in 2014 the number of motorcycles in Kupang City was 125,574 and in 2015 there were 139,033 of which were automatic motorcycles. So that intensive care is needed on automatic motorbikes, with intensive care it will make automatic motorbikes more comfortable when riding. Aurora Motor is one of the motorcycle repair shops in Kupang City. In addition to providing service and maintenance services for two-wheeled vehicles, Aurora Motor also sells various kinds of motorcycle parts. The average number of customers who come reaches ± 15 customers per day, which consists of various types of motorcycles with different weights. Currently, the problem at the aurora motorcycle workshop is that there is no system that can quickly identify the damage that occurs to the motorcycle, resulting in the slow process of repairing the motorcycle. it can be concluded that this application has fulfilled its main purpose, which is an application that can help mechanics at aurora motorbike workshops to determine each level of damage and maintenance on a Honda matic motorbike. This application is able to determine the level of maintenance and damage with forward chaining.

Abstract

This study will discuss the use of the Complementary Filter method in hardware development that use gyroscope and accelerometer sensors, in order to see the ability of the sensor to read movement and assess how effective it is when used under movements with varying levels of aggressiveness. The complementary filter is a method that as the name suggests is to filter input data taken from the gyroscope and accelerometer sensors, this method is able to take data from both sensors and combine them into a single data that is more accurate by ignoring the shortcomings and using the advantages of each sensors The device that will be used is the MPU6050 GY521, this is a device that has both the two sensors on a single PCB so it is easier and more efficient to use, it has 3 axes meaning that this device can read motion in 3-dimensional space, the microcontroller used is a a variant of Arduino with an ATmega processor. After doing the test it was found that the use of the complementary filter method will greatly help the accuracy of the data because the filtered data contains very small noise with a significant difference when compared to raw data without using the filtering method, but because delay still can happens, wich cannot be helped by using this filtering method, this device can only be used with certain levels of movement

Abstract

The rapid advancement of information and communication technology has increased the need for data security and confidentiality in digital information exchange. Various threats, such as eavesdropping, data theft, and information manipulation, require effective security methods capable of protecting message content without attracting unauthorized attention. One of the techniques used to address this issue is steganography, which conceals secret information within digital media so that the existence of the message remains undetectable. This study aims to implement the Least Significant Bit (LSB) method on digital facial images as a medium for embedding secret messages and to evaluate the quality of the resulting stego images. The system was developed using the Python programming language with a Tkinter-based graphical user interface to facilitate the processes of message embedding and extraction. Prior to embedding, the secret message was secured using an XOR encryption operation with a specific key. The embedding process was performed by modifying the least significant bits of image pixels, resulting in minimal visual distortion. Experimental results indicate that the LSB method successfully conceals secret messages while maintaining the visual quality of the cover image. The evaluation produced low Mean Squared Error (MSE) values and Peak Signal-to-Noise Ratio (PSNR) values exceeding 85 dB, indicating a very high similarity between the original and stego images. Furthermore, the hidden message could be accurately extracted using the correct key, provided that the image had not undergone compression or manipulation. Therefore, the LSB-based steganography approach on digital facial images is proven to be an effective method for enhancing information security and confidentiality.

Abstract

Hama serangga seperti nyamuk, lalat, kecoak, dan tikus merupakan masalah kesehatan yang serius karena dapat menjadi perantara penyebaran berbagai penyakit. Penggunaan insektisida sebagai metode pengendalian hama memiliki dampak negatif terhadap kesehatan manusia dan lingkungan. Penelitian ini bertujuan untuk menganalisis efektivitas frekuensi ultrasonik dalam mengusir hama serangga menggunakan pendekatan berbasis Internet of Things (IoT). Sistem yang diusulkan memanfaatkan NodeMCU ESP8266 sebagai mikrokontroler utama, Signal Generator AD9833 untuk menghasilkan frekuensi ultrasonik dalam rentang 20 kHz hingga 50 kHz, dan Speaker Piezo sebagai pemancar gelombang, yang dikontrol melalui aplikasi Blynk. Pengujian akan dilakukan dengan mengamati respons hama terhadap berbagai rentang frekuensi serta faktor lingkungan yang mempengaruhi efektivitas pancaran ultrasonik. Penelitian ini diharapkan dapat menjadi solusi alternatif yang lebih ramah lingkungan dalam pengendalian hama dan memberikan kontribusi dalam pengembangan teknologi IoT untuk aplikasi kesehatan lingkungan.

Abstract

The radio frequency spectrum is a finite resource that plays a crucial role in supporting communication systems, particularly in the aviation sector. Unauthorized use and signal interference within this spectrum can pose serious threats to flight safety. This study aims to develop a classification system for aviation radio signals using machine learning algorithms, namely Random Forest and Support Vector Machine. The dataset consists of tabular monitoring data with two main features: frequency and signal power level. The research process includes data preprocessing, model training, validation through K-Fold Cross Validation, and performance evaluation based on accuracy, precision, recall, and F1-score metrics. Testing was carried out under both simulated and real-world conditions using Software Defined Radio (SDR) equipment. Results indicate that the Random Forest model achieved more consistent performance, with an accuracy of 79.77% and balanced F1-scores across both classes. Additionally, the system was found to be user-friendly and responsive, especially for non-technical operators, thanks to its intuitive visual interface. This research contributes to enhancing the effectiveness of aviation spectrum monitoring and offers potential for future integration with real-time detection systems
