Abstract

This study aims to compare the effectiveness of two methods, Certainty Factor (CF) and Case-Based Reasoning (CBR), in detecting Takayasu's Arteritis. Takayasu's arteritis is a complex disease with varying symptoms, giving rise to difficulties in correct diagnosis. The main aim of this study was to evaluate their performance in the context of such complex disease detection. The main problem faced is the uncertainty in assessing the level of certainty of diagnosis based on symptoms that vary between patients. The CF method uses the confidence factor principle to measure the level of certainty in a diagnosis, while CBR uses knowledge from previous cases to design a diagnosis for new cases. This study uses a dataset that includes information on symptoms and patient history related to Takayasu's Arteritis. The experimental process involves implementing both methods on the dataset, with results including evaluation of accuracy, sensitivity, and specificity levels. The research results highlight differences in the performance of Certainty Factor and Case-Based Reasoning in detecting Takayasu's Arteritis, providing in-depth insight into the advantages and disadvantages of each method. It is hoped that this understanding can help develop a more efficient and accurate detection system to overcome the complexity of diagnosing Takayasu's Arteritis. The percentage results from the two approaches used in diagnosing Arteritis Takayasu disease have been presented. The Certainty Factor Method indicates a confidence level of 94%, while the Case Based Reasoning Method shows a similarity level of 54%. This significant difference reflects the superiority of the Certainty Factor Method in providing a higher level of confidence in diagnosing this disease compared to the Case Based Reasoning approach.

Abstract

This study aims to analyze the influence of digital marketing and customer experience on customer loyalty at INTAKO Sidoarjo. The shift toward digital- based marketing has become a crucial approach for businesses in reaching consumers who are increasingly active in online spaces. On the other hand, a positive customer experience is believed to drive repeat purchases and foster long- term loyalty. This research uses a descriptive quantitative approach, employing a survey method by distributing questionnaires to 96 respondents who are INTAKO customers, whether shopping online or offline. The sampling technique used is accidental sampling. Data were analyzed using multiple linear regression through SPSS version 26. The results indicate that both digital marketing and customer experience have a positive and significant effect on customer loyalty, both partially and simultaneously. Among the two, customer experience is found to have the most dominant influence. These findings suggest that building customer loyalty is not solely dependent on the presence of digital platforms, but also on the quality of experience delivered in each customer interaction.
