Abstract

Dissolved Oxygen (DO) is an important parameter for maintaining water quality in aquaculture systems. The accuracy of DO sensors significantly affects the reliability of Internet of Things (IoT)-based monitoring systems. This study aimed to calibrate the DO sensor using a two-point calibration method and evaluate the accuracy of the sensor readings compared with those of a reference device (standard DO meter). A key novelty of this study lies in its multi-media calibration, performed directly on six distinct aquaculture water types, providing field-realistic validation conditions not commonly explored in previous studies. Furthermore, the accuracy of the calibrated sensor is evaluated quantitatively using MAE, RMSE, and percentage deviation to ensure rigorous performance assessment. The system was developed using an ESP32 microcontroller, DO sensor (SEN0237), DS18B20 temperature sensor, and ADS1115 ADC module. Testing was performed on six types of aquaculture water media and compared with a standard DO meter using a comparative approach. In total, n = 6 field measurement points (one stabilized reading per water medium) were used to compute MAE, RMSE, and percentage deviation. The comparison results showed that the calibrated sensor had high accuracy, with a Mean Absolute Error (MAE) of 0.1083 mg/L and a Root Mean Square Error (RMSE) of 0.2654 mg/L. Significant deviations occurred only in one type of water medium, whereas the other five showed results consistent with the reference device, indicating stable sensor readings. These findings confirm that proper calibration can improve the accuracy and reliability of IoT systems used for water-quality monitoring. Regular calibration is required to maintain the sensor performance, particularly for long-term use in dynamic aquaculture water environments.

Abstract

Pengenalan teks pada citra nota menggunakan Optical Character Recognition (OCR) masih relevan diteliti karena tingginya variasi kualitas citra. Penelitian ini mengevaluasi kinerja Tesseract dan EasyOCR dalam mengenali teks pada citra nota dengan beberapa metode prapemrosesan. Dataset berasal dari Kaggle dengan 50 sampel citra yang dipilih menggunakan stratified sampling. Pengujian dilakukan dengan menghitung Character Error Rate (CER) antara hasil OCR dan ground truth. Hasil menunjukkan nilai CER berada pada kisaran 18%–25%, dengan performa terbaik Tesseract pada mode denoise dan EasyOCR pada mode grayscale. Metode threshold memberikan penurunan akurasi paling signifikan. Kualitas citra dan jenis prapemrosesan terbukti memengaruhi kinerja OCR, sehingga pemilihan prapemrosesan yang tepat sangat penting dalam meningkatkan akurasi pengenalan teks pada citra nota.

Abstract

This study presents the development of a fire detection system using image processing techniques based on the YOLOv8 object detection algorithm to achieve fast, accurate, and real-time performance. A dataset of fire images with various visual characteristics was preprocessed, converted into YOLO annotation format, and used to train the model for 30 epochs. Evaluation results demonstrate that the YOLOv8 model performs effectively, achieving an mAP50 of 0.646, a precision of 0.889, and an inference speed of 282.5 ms per frame. The system is integrated with OpenCV to process webcam input and display bounding boxes and confidence scores in real time. The implementation confirms that YOLOv8 is a reliable solution for early fire detection, offering faster and more adaptive responses compared to conventional sensor-based methods. This approach can be applied to modern safety monitoring systems to enhance fire prevention efforts.

Abstract

As a regional flagship commodity with a promising selling value, the process of grouping the maturity level of Medan Orange is still dominated by manual visual techniques. This often triggers data inconsistency and requires a long duration of processing due to personnel subjectivity factors. This research aims to compare the performance of two machine learning algorithms, namely KNN and SVM, in classifying the maturity level of Medan Orange fruit based on digital images. The dataset used is a primary dataset collected directly from Medan Orange farmers in field conditions. The research stages include image acquisition, pre-processing, extraction of HSV-based color features and GLCM-based textures, as well as classification of maturity levels into three classes, namely raw, semi-cooked, and mature. The performance of both algorithms is evaluated using accuracy, precision, and recall metrics. The research results show that the KNN algorithm has a superior performance compared to SVM, with an accuracy rate of 96,25%, while SVM produces an accuracy of 91,25%. This result shows that KNN is effective and more suitable to be applied to the automation system of classification of the maturity of Medan Orange fruit based on digital images.

Abstract

Accurate people counting in dynamic environments remains challenging due to variations in lighting, complex backgrounds, and occlusion. This study proposes a video-based people counting system leveraging a Convolutional Neural Network (CNN) integrated with the YOLOv5 object detection model. The system applies a structured preprocessing pipeline, including frame extraction, normalization, and noise reduction, to enhance data consistency before detection. The model was evaluated using ten real-world campus video sequences to assess detection reliability and counting accuracy. Experimental results demonstrate that the proposed method achieves high precision and recall for real-time detection across diverse scenarios. Performance degradation was observed in frames containing dense crowds or low illumination, indicating limitations under extreme conditions. These findings validate the feasibility of lightweight CNN-based detectors for surveillance and monitoring applications, while highlighting the need for larger datasets and optimized training strategies to improve robustness in more complex environments.

Abstract

Software testing is a crucial stage in the development cycle to ensure program functionality runs as expected and maintains good quality. This process aims to identify errors so they can be fixed before the software is released to users. One of the software objects of this research is the Teman Ternak website. Teman Ternak is a website-based digital platform that functions as telemedicine, designed to overcome distance and time barriers between farmers and veterinarians, providing a platform that allows farmers to obtain remote consultation services, including initial diagnosis and treatment for diseases affecting their livestock. Testing on this website was conducted using the Black Box Testing method by applying the Equivalence Partitions technique. The Black Box method is used to test website functionality from a user perspective without needing to know the internal code structure. Meanwhile, the Equivalence Partitions technique is a testing technique that focuses on designing test cases by grouping input data on each form on the Teman Ternak website. Input data is grouped into test classes (test cases) with expected results of valid or invalid values. The purpose of testing on the Teman Ternak website is to detect and minimize functional failures during implementation, so that errors found can be fixed more quickly and the website quality improves.
