Abstract

Globally, cardiovascular disease is among the major diseases that lead to death. Early forecasts are crucial. Using the patient's medical record, the supervised learning algorithm for predicting heart disease at an early stage was proposed. The principal component analysis (PCA) classifier and decision tree algorithm were created to classify medical record data. To predict cardiovascular diseases, data mining was utilized. The proposed strategy improves the diagnostic efficiency of physicians. Using data received from the UCI repository, the classifier's efficacy was confirmed. PCA offers 98% precision, 100% sensitivity, and 98% accuracy. In terms of accuracy, sensitivity, and precision, the results showed that the PCA outperformed the decision tree.

Abstract

The central resource manager of Hadoop Yet Another Resource Manager (YARN) has posed a major concern to big data analysis and exploration. The central arbiter is overwhelmed whenever there are resource requests by application masters and heartbeat communication from several name nodes in the Hadoop cluster; thereby, degrading the performance of the framework. An attempt to decentralize the resource manager's responsibilities by introducing a new layer in the cluster named the Rack Unit Resource Manager (RU_RM) layer increased cluster performance but introduced a fault-tolerance concern. This work, therefore, developed a fault-tolerant model to allow for efficient and effective data analysis in the Hadoop cluster. A pseudo-distributed computation was set up with the help of the YARN Scheduler Load Simulator (SLS) and WordCount operation performed with varying input sizes. Two fault scenarios were presented and the results obtained showed that with an increase in input size (workload), the running time of the developed fault-tolerant model though slightly higher than that of the existing model, is significantly negligible when compared to the computation bottleneck incurred anytime RU_RM fails. The developed model, therefore, has good performance in the presence of failure of a unit (RU_RM) in the cluster.

Abstract

The purpose of this research is to develop an Internet of Things (IoT)-based automated bread dough mixing machine monitoring system using ultrasonic sensors and an integrated load cell sensor with a solenoid valve. The system is designed to control the distance between each bowl of dough ingredients and measure the weight of the mixed dough using a smartphone as the control interface. Additionally, the system allows users to issue on/off commands to the solenoid valve. This system provides detailed monitoring of the mixed blue dough ingredients. The research is conducted through several stages, including literature review, system design, hardware development, software development, implementation and integration, and testing. The testing phase involves both hardware and software components to ensure their functionality.

Abstract

Many studies have confirmed that the application of information technology has helped humans to be more efficient in carrying out their activities. The daily repetition at the 5 Brebes State High School, using the conventional method, with the question of the written examination, it poses some challenges such as, teachers take quite a long time to correct the answers, since one teacher can teach up to 7 classes, another obstacle when examining is cheating by students during the examination. This research aims to develop and evaluate a Computer Based Test based on a Website, thus making it easier for teachers to correct students' answers, which are dual-choice, because the results of the correction will automatically exit the system and the application of the Fisher-Yates Shuffle algorithm will be able, minimizing the level of student fraud, because questions are spotted for each student. System development will use the Waterfall method with phases, analysis, design, program code making, testing. Based on the random permutation calculation of an existing question, when there are 15 questions but only show 10 questions, it results in permutations of 360.360 models, then the probability calculation that has been done yields 0,00832%, the chances of 30 students getting the same sequence of topics of 15 existing questions. Based on the results of the validation test, the comparison of the correction time for one class with the issue of double selection, which previously took 15 minutes, while using a Computer Based Test of 32 seconds. While the level of cheating is minimized, because the sequence of matters presented to each student will be different.

Abstract

As technology advances and digital transactions continue to grow, many companies are now launching digital or cashless transaction applications. This allows users to be more selective in choosing a digital or cashless transaction application, also known as an e-wallet, that they want to use. Factors considered in this selection process include ease of use, offered features, transaction speed, security, and the number of merchants available. This research aims to provide users with information to choose a high-demand e-wallet by implement the Technology Acceptance Model (TAM) to calculate the selection of a high-demand digital wallet. Based on the data calculated using the TAM method and survey results that include appearance criteria, offered items, convenience, security, and the number of merchants, GO-PAY is considered the primary alternative for a digital wallet with a demand rate of 47.8%. OVO comes in second place with 31.1%, followed by DANA in the last position with 21.1%
