Abstract

The development of information technology has an impact on the number of information systems in various fields as a form of implementing technological needs in the digital era. Gold shop is one type of business that requires an information system because there are still many transaction processes that are processed manually so that errors occur in the reports. Adil Gold Store is one of the largest gold shops in Banyumas Regency, which has 6 main branches, namely Wangon, Ajibarang, Cilongok, Pemalang, Jatilawang and Cilacap. Adil Gold Store requires an information system with centralized data, meaning that both buying and selling of gold can be monitored in one application by the owner. Management of product stock and inventory is also still manual which is ineffective. The additional innovation needed is the need for a mobile application for members. Based on these needs, an information system was created using the prototype method. This is because the gold shop is a very complex system and requires more in-depth analysis. The result of developing this system is a gold shop website equipped with a mobile application for members. The results of system testing show that performance is considered quite good because the testing accuracy of each role is above 90%, but some system errors still need to be fixed so that they can actually run properly

Abstract

A brain tumor is a type of disease that is quite dangerous in the world. This disease is one of the main causes of human death and has a high risk of recurrence. There are several types of brain tumor locations such as edema, necrosis to elevation. Segmenting the location of this disease is important to do to support faster recovery efforts. The Convolutional Neural Network (CNN) algorithm, which is part of the deep learning method, can be an alternative to this segmentation effort. The U-Net architecture is part of the CNN algorithm which specifically works on medical image segmentation. This study experimented to build a special U-Net architecture for medical image segmentation that had been optimized with SGD. The data used is BraTS2020O which contains a collection of MRI data. This optimization aims to improve the performance of the U-net architecture for segmenting brain tumor images. The results of the study show that the SGD optimization carried out has succeeded in providing better performance than previous studies. This can be seen from the performance value obtained at 0.9879. This accuracy value indicates an increase in accuracy from previous studies. High accuracy indicates that the SGD-optimized model has good segmentation prediction performance.

Abstract

Diabetes is a widespread medical condition affecting a substantial portion of the global population. It is a metabolic disorder known as diabetes mellitus, characterized by severe fluctuations in blood glucose levels due to inadequate insulin production in the human body. The effective monitoring of diabetes is of paramount importance to researchers as it holds the potential to enhance the quality of healthcare services. Among the challenges faced by individuals with diabetes, one prevalent issue is the development of ulcers, which can be challenging to detect promptly. Technological advancements offer a promising avenue for cost-effective and continuous monitoring of chronic diseases like diabetes. This study centers on the development of IoT-based intelligent diabetic footwear that incorporates pressure sensors and temperature monitoring for individuals with diabetic feet. In the evaluation of SX1278 (Ra-02) Lora Module communication, deployed at eight different locations, it was observed that two of these points achieved a flawless transmission success rate of 100%. Conversely, the communication failed at points 6 and 7, with a success rate falling below 50%. Some of these failures can be attributed to signal obstructions, including natural elements such as trees and terrain, as well as man-made structures like buildings and machinery workshops, which hinder the efficient transmission of signals from the end node to the gateway. The results of this research provide positive implications in the form of developing IoT-based diabetes shoes that can be applied with alternative Lora communication connections in areas with poor internet signal.
