Abstract

Early detection of heart disease is crucial given the high number of cases occurringin advanced stages and affecting individuals in their productive years. Utilizing data mining, the C4.5 Algorithm is one method capable of detecting the onset of heart disease, prompting timely awareness and early prevention. The dataset employed is the Heart Disease Cleveland UCI from Kaggle, featuring 13 input attributes and 1 target attribute. Using the Decision Tree method results in decision-making by constructing a decision tree. The test outcomes revealed an accuracy rate of 77.11% with the C4.5 algorithm, 83.69% with the C4.5 algorithm employing Forward Selection, and 84.73% with the C4.5 algorithm based on Forward Selection and Particle Swarm Optimization.

Abstract

The software developing process is a very complex process, because it includes department, company, and individual which have different knowledge and specialization. Additionally, the demand to distribute the software on time and minimum cost, and the extreme competition between the software developers causing new problems and uncertainty. Therefore, the software developing project rely on the adequate project management to achieve the best result to fulfill the previously set parameters of time efficiency, cost, and quality. At a glace, the risk management perhaps increase the complexity of the process itself, but the fact it can reduce the risk and complexity of this software developing project. This journal applies literature review method, and the data are from the research results published in the national and international online journals, and books review the risk management of software developing project. The writer’s research results bring out that the risk factors are found in the software developing process, including the project documentation risk, communication, human resources, culture, bug severity level, and bug repair priority level.
