Abstract

Chronic Kidney Disease (CKD) has become a significant global health issue, with its prevalence rising sharply, particularly in developing countries like Indonesia. According to the Kementrian Kesehatan (KEMENKES), the Synthetic Minority Over-sampling Technique (SMOTE) has been widely adopted to address this. SMOTE generates synthetic samples for the minority class, enhancing the model’s ability to identify high-risk patients. Studies demonstrate SMOTE’s effectiveness, particularly when combined with ensemble learning algorithms like Random Forest and Gradient Boosting. The data collection focused on relevant medical parameters critical for the study, encompassing laboratory test results, diagnostic reports, and clinical observations related to kidney function. This dataset in kidney disease is used to predict whether someone has chronic kidney disease or not with a total sample of 400 data obtained from the Ungaran Regional Hospital and several clinics that can detect kidney disease. Recent research highlights that SMOTE significantly improves model accuracy, with Random Forest achieving 99.30% accuracy. These findings emphasise the importance of data balancing in enhancing diagnostic precision, offering promising avenues for early CKD detection and improved patient outcomes.

Abstract

This study applies an integrated FP-Growth algorithm with MongoDB and Python to analyze 150,000 minimarket transaction records over a one-year period. The dataset includes transaction numbers, product names, quantities sold, transaction dates, purchase prices, and selling prices. The parameters of a minimum support of 0.001, a confidence of 0.01, and a lift above 1.0 are used to ensure relevant association rules. The analysis indicates that the discovered product association patterns can increase operational efficiency by up to 15%, particularly in instant food and ready-to-drink beverage categories. These data-driven strategies also boost sales volume by 12.3% and reduce dead stock by 8.7%. Beras MCS 5KG stands out as the most profitable product, with a margin of IDR 1,066,724,400. The main strength of this study lies in the integration of FP-Growth with MongoDB, enabling large-scale real-time analysis without generating candidate itemsets. This approach enhances data processing efficiency, allowing minimarkets to optimise inventory and promotional strategies more accurately.

Abstract

 In repairing a television (TV), it is necessary to understand the symptoms experienced by the TV. Therefore, technicians need to conduct an initial analysis of the causes of these symptoms. Analysis of the causes of TV damage can be predicted using a technological approach, one of which is by using an expert system. This study will focus on developing an expert system to predict the causes of TV damage. This study will apply the Random Forest method to predict TV damage based on historical datasets obtained from company X. Company X is a company engaged in the repair of electronic devices, one of which is TV. The data obtained will be used as training data to create a model that can predict the causes of TV damage. Then the experiment was carried out with a quantitative approach with experiments to optimise the model in increasing prediction accuracy. The model was evaluated using accuracy metrics. The results of the study showed that Random Forest has very good performance in classifying the causes of TV damage with a high level of accuracy reaching 100%. However, this study is only limited to certain historical data and does not consider external factors that influence damage to the TV.

Abstract

Health and nutrition in the elderly play a crucial role in determining the quality of human resources, especially for the elderly themselves. The ageing process causes a decrease in the ability of body tissues to regenerate, making the elderly more vulnerable to infections and organ damage. Indonesia is currently experiencing an increase in the number of elderly, from 18 million people (7.56%) in 2010 to 25.9 million people (9.7%) in 2019, and is predicted to reach 48.2 million people (15.77%) in 2035. This study aims to determine the most effective algorithm for identifying the nutritional status of the elderly, by comparing three algorithms, namely Decision Tree, K-Nearest Neighbor (KNN), and Naïve Bayes. The methodology applied is CRISP-DM, and algorithm performance evaluation is carried out using the accuracy metric of the Confusion Matrix. The results showed that Decision Tree achieved the highest accuracy (95.55%), followed by Naïve Bayes (94.18%) and KNN (94.01%). The combination of algorithms provides optimal results because each algorithm can capture different patterns in the data, so the integration of the results can reduce errors and increase accuracy in the classification of the nutritional status of the elderly.

Abstract

This research aims to analyse the influence of Enterprise Architecture (EA) on Digital Self-care Services (DSS) at PT Wahana Sukses Makmur. The background of this research is based on the company's need to improve the efficiency of digital services through better system integration. However, there are still gaps in the optimal implementation of EA to effectively support DSS. Therefore, this study examines the extent to which EA contributes to improving the quality of the company's digital services. This research uses a quantitative method with a simple linear regression approach. The population in this study were customers of PT Wahana Sukses Makmur, with a sample size of 100 respondents selected through appropriate sampling techniques. Data was collected through a questionnaire that measured customer perceptions of EA implementation and DSS quality. The results showed that EA has a significant influence on DSS, with an F test value of 104.070 and a significance level of 0.000 (p < 0.05). In addition, the t-test results show a regression coefficient of 0.875, which indicates that each one-unit increase in EA implementation will increase the quality of DSS by 0.875 units. Theoretically, this study confirms the important role of EA in supporting DSS development through improved system integration and optimisation of digital processes. The practical implications of this research suggest PT Wahana Sukses Makmur adopt a more structured enterprise architecture to improve operational efficiency, accelerate digital services, and create a more responsive and user-friendly customer experience.

Abstract

This study aims to compare the efficiency and accuracy of the Apriori and FP-Growth algorithms in determining frequent patterns from sales transaction data. In addition to evaluating execution time and the quality of the generated association rules, the study also examines the algorithm's advantages on small to large-scale datasets. The data used were collected from G Coffee’s sales transactions during the period from September 1 to November 30, 2024. After undergoing preprocessing stages, both algorithms were tested using three dataset variations to identify common association patterns, such as the relationship between “Mineral 660ml” and “Kopi Susu Aren,” along with other product combinations with high confidence and significant lift values. The results show that FP-Growth had a faster execution time (0.3008) compared to Apriori (0.5833), without compromising the accuracy of the results. Although both algorithms generated identical association rules, FP-Growth was superior in computational efficiency due to its ability to avoid explicit candidate itemset generation. These findings offer strategic benefits for companies, particularly in enhancing product promotion through bundling, cross-selling, and product grouping based on consumer purchasing patterns. Results, a hybrid approach is recommended to combine the processing speed of FP growth with Apriori’s flexible parameter adjustment, enabling more optimal analysis of purchasing patterns in large and complex datasets.
