Abstract

Regular detection of cracks on the road surface is a necessary link to ensure the safety of road users. There are several traditional methods that have been developed to detect road cracks, but there are still many shortcomings in these traditional methods. The inefficiency of conventional methods has led to the development of automatic detection methods using image processing. This research aims to detect road surface cracks using the thresholding method, median filter, and morphological techniques applied to 40 road surface images which are divided into training data and test data. Processing image data for road surface crack detection in this research uses the Open CV tool. From these results it was found that this method can be applied with a success rate of 85%.

Abstract

Abstract— Toko Jaya Indah Bangunan is one of the shops located in Tanjungpinang city and is engaged in selling and providing building materials. Toko Jaya Indah Bangunan is located at Jalan Gatot Subroto. In procuring building materials, Toko Jaya Indah Bangunan usually first checks the stock of goods in the warehouse and also sees what trend in the market for goods is currently booming. If you have found the goods to be held and the goods are currently booming, then Toko Jaya Indah Bangunan will procure the goods. The problem that arises in procuring goods like this is that sometimes the number of goods ordered does not match what is needed by the community, causing stockpiles of goods to accumulate in the warehouse and hindering Toko Jaya Indah Bangunan in ordering other goods. This can be overcome if the Toko Jaya Indah Bangunan has a system that is able to check the available stock of goods directly without having to check the warehouse first, and also determine the number of items held using a prediction system. The methodology used for the development of this application is the waterfall methodology, the reason is because this method has stages of application development that are in accordance with the way the author developed this application by going through the stages of analysis, design, coding, testing and application. And for the calculation method in making this prediction, the author uses the Single Exponential Smoothing method which this method uses reference data that has a fixed pattern. This prediction model was chosen because the data obtained contains a stationary pattern (tends to be fixed and does not change). From the results of the design, we get a system that is able to predict the exact amount of the purchase of an item made by Toko Jaya Indah Bangunan and this prediction system is made using the Java language, MySQL database and desktop-based.

Abstract

Stingless bees play an important role as natural pollinators in ecosystems and as producers of economically valuable products such as honey, propolis, and bee bread, which are utilized in the food and health industries. Identifying stingless bee species remains a challenge due to the many species with similar morphology, requiring more efficient and accurate methods. This study aims to develop an automatic system based on image processing technology for the identification of stingless bee species using Convolutional Neural Networks (CNN), TensorFlow, and the Single Shot MultiBox Detector (SSD) implemented with OpenCV. The test results showed that the developed system was capable of automatically detecting and classifying stingless bee species with an average accuracy of 98%, especially when the object was directly aligned with the camera. Out of 40 tested samples, 31 samples were recognized, and 9 samples were not, resulting in a success rate of 77.5%. Factors influencing detection success include the quality of training data, camera positioning, and morphological similarities between species.

Abstract

Personal data breaches in Indonesia have become increasingly prevalent, posing significant risks to both individuals and businesses. With the rapid advancement of information technology, this issue has sparked intense discussions on social media, particularly on the X (Twitter) platform. This study aims to analyze user sentiment on X regarding personal data breaches by classifying opinions into positive, negative, and neutral sentiment categories. Additionally, this research evaluates the performance of the classification model using a confusion matrix to measure accuracy, precision, recall, and f1-score. The method used in this study is the Naïve Bayes Classifier, with 70% training data (433 data points) and 30% testing data (186 data points). The data was obtained through web crawling and preprocessed before performing sentiment classification. The results indicate that negative sentiment dominates with 43.54%, followed by positive sentiment at 28.50%, and neutral sentiment at 27.96%. Model evaluation achieved an accuracy of 98.92%, with negative precision 100%, neutral precision 100%, and positive precision 96.30%. Meanwhile, recall for both positive and negative sentiment reached 100%, while recall for neutral sentiment was 96.23%. The f1-score for negative, neutral, and positive sentiment was 1.0, 0.988, and 0.981, respectively. These findings demonstrate that the Naïve Bayes Classifier performs exceptionally well in classifying sentiment related to personal data breaches. The dominance of negative sentiment in the classification results reflects high public concern over this issue, highlighting the urgent need for enhanced data security measures and privacy protection in Indonesia.

Abstract

The profession of fishermen requires a reliable system to remove stagnant water from fishing boats, as manual drainage is time-consuming and inefficient. This study proposes an IoT-based automatic water drainage system without using an inverter or ultrasonic sensor, offering a cost-effective alternative. The system utilizes a water level sensor and a DC water pump, controlled via a smartphone application. The research model used is the Research and Development (R&D) model, through several stages, namely potential and problems, initial data needs, prototype creation, prototype validation, prototype revision, validation, implementation. Problems occur at the prototype stage, problems that must be revised include aspects of wiring, Power Suitability, Water Level Sensor Test, and the configuration of the relay used. The IOT-based automatic water drainage system can function based on the results of white-box testing including Hardware Implementation, Software Implementation, Implementation of Application Usage, and Automatic Drainage System Testing. This is indicated by the results of the Liquid Water Level Sensor Functionality test, DC Water Pump Functionality Test, Solar Panel and Battery Functionality Test, and IOT Functionality Test. IOT-based automatic water discharge systems on fishing boats are more efficient and cost-effective in the long run, although diesel engines offer more reliability under adverse weather conditions or in places with limited access to sunlight.
