Abstract

The importance of advancing sustainable rice farming is because rice is a staple food whose production must be increased to meet the basic needs of the community. The problem that occurs to rice farmers is that thousands of bird pests look for food in fertile rice fields, causing great losses for farmers. The way farmers efficiently repel bird pests is by developing technology that can monitor bird activity around rice fields in real time remotely and is able to repel bird pests by using the Internet Of Things (IoT) development. which aims to design IoT or tools that can monitor bird activity in real time around agricultural areas remotely, by utilizing PIR sensors to detect bird pests, LDR resistors detect light, ESP32-CAM to monitor rice fields and utilizing solar panel power as a sound signal generator that will sound disturbing the bird's hearing system so that the birds fly away and move the DC motor to repel bird pests automatically and the data collected from the ESP32-CAM (1) sensor will be sent to the IoT platform with the Telegram application connected via an internet connection, allowing farmers to monitor remotely via smart devices such as smartphones or computers.

Abstract

Nutrition is a very important aspect for the human body, especially in toddlers and children. Balanced nutrition not only supports children's growth and development, but also improves academic achievement and contributes positively to their future development. However, in Tumpiling Village, the problem faced is the low basic understanding of parents and Posyandu cadres regarding balanced nutrition in early childhood. This causes toddlers to still be found with malnutrition or obesity, as well as a lack of data collected based on children's nutritional characteristics. Clustering, as one of the popular methods in processing medical, biometric, and various other fields of data, is known for its simplicity and effectiveness in grouping large-scale data based on similar characteristic. This study aims to groups the nutritional status of toddlers based on height and weight parameters using the K-Means Clusterings algorithm. This grouping produces several categories of nutritional status, namely obesity, overnutrition, good nutrition, undernutrition, and poor nutrition. By applying the Clustering method using K-Means, the nutritional status of toddlers can be classified more clearly, so that it can be a basis for Posyandu cadres in taking early preventive measures against malnutrition and obesity. In this study, the author used 28 toddler data. From the data, the author randomly determined the cluster center of 5 data, which then resulted in the following grouping: 7 toddlers experienced malnutrition, 3 toddlers were undernourished, 6 toddlers with good nutrition, 7 toddlers were overnourished, and 5 toddlers were obese. These results indicate the need for further attention and action from Posyandu and Puskesmas cadres to help parents in overcoming toddler nutrition problems

Abstract

The accumulation of waste in certain locations, especially in residential areas, due to the continuous accumulation of waste can cause environmental disturbances such as disease and unpleasant odors. This system is designed to find out whether the trash bin is full or not by applying fuzzy logic, if the status of the trash bin can be cleaned, it will be handled immediately so that the waste does not accumulate and disturb people around. This system can find out when the last time the waste was taken and the location of the trash bin as a prototype which can later be applied to areas with a wider range by cleaning service officers in Mamuju City. This system uses the HC-SR04 sensor to detect the distance of the waste to the sensor and uses the Load Cell sensor to detect the weight of the waste. Several tests were carried out, first by measuring the accuracy of each sensor used, the HC-SR04 sensor accuracy was obtained at 96.68% with an error of 3.32%. While the accuracy of the load cell sensor is 90.68% with an error of 9.32%. The second test calculates the sensor response time and Blynk notification response since the sensor detects waste, the average HC-SR04 sensor detection response is around 0.83 seconds. For the response time of incoming notifications when there is movement in the HC-SR04 sensor area has an average of 2.65 seconds. While the Load Cell sensor response time is only around 0.53 seconds. For Blynk notification response time since the Load Cell sensor detects it has an average of 2.51 seconds. The third test calculates the response time of the two sensors (HC-SR04 and Load Cell) and the Blynk notification response since the two sensors detected the waste, the average response time of the two sensors finished detecting only around 0.91 seconds. For the response time of the trash bin status condition, if there is movement in the area of the two sensors, the condition of the trash bin will change and display the status of Normal, Needs Cleaning and Highly Needs Cleaning with an average response time of 1.18 seconds. The system successfully sends notifications according to the fuzzy rules and expected to speed up the waste handling process

Abstract

Facial expression recognition technology has advanced significantly and has become an intriguing topic of study. This research focuses on the facial expressions of Al-Qur’an memorization students, which naturally reveal various aspects of their engagement, understanding, and emotional barriers about the verses being memorized. The issue is that facial expression recognition still lacks optimal accuracy, and the need for a better algorithmic model to improve accuracy is evident. Therefore, an intelligent computing system is required to address this problem. This study aims to enhance the accuracy of facial expression recognition in Al-Qur’an memorization students using the Convolutional Neural Network (CNN) method, classifying facial expressions such as happy, neutral, and tired based on collected facial image data, achieving improved accuracy. The first stage involves capturing image data via CCTV, followed by preprocessing, training the CNN model, result analysis, and model evaluation. By using the CNN method to recognize the facial expressions of Al-Qur’an memorization students, a high accuracy of 84% was achieved with a loss value of 14.9.

Abstract

Pneumonia is an inflammation of the lungs that causes pain when breathing and limits oxygen intake. Pneumonia can be caused by bacteria, viruses, and fungi. Image processing, a branch of informatics or computer science, is a field highly related to the manipulation and analysis of digital images. This study aims to design a medical image processing system as an alternative to support the diagnosis of Pneumonia in the lungs using the LS-SVM method. LS-SVM (Least Square Support Vector Machine) is a simpler and modified model of the SVM method. HoG (Histogram of Gradient) is a commonly used feature extraction method in image processing and object detection. The objective of this study is to improve the quality of healthcare services and assist in faster and more accurate clinical decision-making. The results show that lung image analysis using the LS-SVM method has a good accuracy level in the image classification process, with 2000 training data inputs processed in the preprocessing stage, consisting of 1000 Pneumonia images and 1000 normal lung images, while the testing data used consisted of 500 images, with 250 Pneumonia images and 250 normal lung images. Based on the tested data, the system achieved an accuracy of 81% for 1300 tests, proving that the LS-SVM method is effective in image processing with satisfactory results.

Abstract

The widespread distribution of digital images on the internet has diminished the copyright protection associated with them. In some cases, copyrighted and economically valuable digital images should not be modified or distributed without permission, as altering the original image can harm its owner. This violation is common, but many internet users are unaware of it. The goal of this research is to protect intellectual property rights of digital images using visual cryptography based on the Hill Cipher algorithm with matrix key flexibility. Hill Cipher is chosen for its ability to encrypt data in blocks, making it more secure than classical cryptographic algorithms that encrypt data individually. Visual cryptography is used to secure digital images through encryption and decryption. Encryption scrambles the image, while decryption restores it. The research method involves collecting digital image datasets, preprocessing, Hill Cipher encryption, and decryption. Key flexibility includes matrix keys of 2x2, 3x3, and 4x4 to enhance security. This research has demonstrated the effectiveness of the Hill Cipher algorithm in protecting digital images through encryption and decryption processes with flexible matrix keys of size 2x2 and 3x3. The results of the experiments, including encryption and decryption using both matrix sizes, have been thoroughly analyzed with respect to various cryptographic metrics: histogram analysis, energy, entropy, and running time.
