Abstract

Environmental issues are still one of the problems that need special attention. Among the problems regarding the environment, waste is one of the problems that is difficult to overcome. This is due to the high consumptive behavior of the community that produces a lot of waste or garbage. Smart trash cans use proximity sensors to make the trash can lid open automatically. To increase accuracy and simplify settings on smart trash can automation, in this research the author uses the Fuzzy logic algorithm. Smart trash cans are made with ultraviolet sensors based on Arduino Uno which are embedded with fuzzy algorithms so that the sensors can have better accuracy, easier settings, and are more resistant to interference. Based on the test results, the automatic trash can system using ultrasonic sensors can work well in various environmental conditions. The ultrasonic sensor used in this research has an accuracy of 95%. This means that the ultrasonic sensor can detect the presence of humans when trying to take out the trash with a high level of accuracy.

Abstract

College assignments play a crucial role in enabling students to grasp course material and achieve learning objectives. However, the demands of completing assignments from multiple courses often leave students confused about prioritizing tasks. This can lead to suboptimal assignment completion and potentially lower the quality of learning. This research aims to assist students in effectively prioritizing college assignment completion using the greedy algorithm. This algorithm will aid students in creating optimal assignment scheduling by considering various factors such as deadlines and assignment difficulty. The research methodology employs simulation with diverse courses as variables and different weights, such as deadlines and assignment difficulty. Preliminary results indicate that the implementation of the greedy algorithm prioritizes assignment deadlines over assignment difficulty, potentially enhancing assignment completion efficiency, leading to more timely task completion and a reduction in student stress levels. The anticipated outcome of this research is to provide students with a method for completing college assignments more efficiently and effectively. This could contribute to improving learning quality and achieving positive learning outcomes. By adopting this approach, students can directly benefit from the research in their academic lives, reducing stress and enhancing their productivity.

Abstract

In this modern era, eating disorders in children are receiving increasing attention due to their significant impact on physical health, mental well-being, and overall development. Diagnosing eating disorders in children is often complicated due to the varying symptoms and the difficulty children have in articulating or understanding their conditions. Additionally, traditional diagnostic approaches often rely on subjective assessments and clinical expertise, which can lead to misdiagnosis or delays in appropriate intervention. This study aims to develop an expert system for diagnosing eating disorders in children using Dempster-Shafer Theory as the primary inference engine. This approach is chosen for its strengths in handling uncertainty and incomplete information, allowing the system to make diagnostic inferences based on observed symptoms, even when the information is ambiguous or incomplete. The system is designed to leverage computational algorithms and medical knowledge, providing reliable and consistent results. From tests conducted on a sample of 30 randomly selected cases, the system achieved an accuracy rate of 93.33%, demonstrating that this approach is highly effective in diagnosing eating disorders in children. The developed expert system, web-based, is equipped with key features that enable diagnosis based on symptoms and provide diagnostic results along with recommendations for appropriate medical actions.

Abstract

Convolutional Neural Networks (CNN) have become the dominant algorithm in image classification and prediction due to their ability to recognize complex visual patterns. However, to achieve optimal performance, CNN models require various optimization techniques. This study aims to explore and implement optimization techniques in training CNN models to enhance the accuracy and generalization capabilities of the model in image classification. The techniques implemented include learning rate scheduling, batch normalization, regularization with dropout and L2, data augmentation, and the use of transfer learning with pre-trained models such as VGG16. Additionally, early stopping methods and advanced optimization algorithms like Adam and RMSprop are applied to improve convergence and prevent overfitting. The results show that the combination of applied optimization techniques significantly improves the performance of CNN models. Analysis of the model training history visualization indicates a reduction in loss and an increase in accuracy, with slight indications of overfitting towards the end of training. These findings emphasize the importance of employing holistic optimization strategies in developing CNN models for image classification and prediction applications. However, in some experiments, the trained models still exhibited prediction errors. This can be attributed to factors such as overfitting or underfitting, data quality and quantity, data diversity, model architecture, and optimization methods. Therefore, further optimization is needed in data preparation, determination of optimization methods, and data cleaning.

Abstract

Ovarian cysts are a disease that only affects women and attacks the ovaries. Many people don't know about this disease, including its causes, symptoms and how to prevent it. In the world of health, there are still several problems in diagnosing diseases, especially ovarian cysts. Some lay people have no knowledge about this disease and often experience difficulties due to limited doctor schedules or the availability of specialist doctors in hospitals. Many patients want to consult or find out whether there are ovarian cysts in their pregnancy. The aim of this research is to build a knowledge-based system in the medical field that uses a combination of Forward Chaining and Certainty Factor methods to diagnose ovarian cysts. The Forward Chaining method is used to find conclusions based on cause and effect using the IF-THEN rule, while the Certainty Factor is used to provide a weight value (Expert CF) that has been determined by the expert in order to get maximum results. The result of this research is an expert system application that combines the Forward Chaining and Certainty Factor methods in diagnosing ovarian cysts. This application is intended for the public by carrying out an initial diagnosis based on the symptoms that have been input, using rules from the Forward Chaining method and calculating certainty values ??using the Certainty Factor method. With this application, it is hoped that it can help people find out about the disease they are suffering from and provide the information needed to take further action.
