Abstract

Kita sering menjumpai antrian di tempat-tempat yang menyediakan layanan publik, seperti restoran cepat saji, kantor pos, supermarket, taman hiburan, dan banyak lagi. Distribusi kedatangan, distribusi waktu pelayanan, fasilitas pelayanan, disiplin pelayanan, ukuran antrian, dan sumber panggilan merupakan elemen penting dari sistem antrian. Penelitian ini dilakukan untuk menentukan pelayanan yang optimal sehingga pelayanan pengunjung pada wahana hiburan menjadi lebih efektif, efesien,dan memuaskan para pengunjung yang datang ke wahana tersebut. Antrian terjadi ketika ada pelanggan yang harus menunggu untuk mendapatkan pelayanan. Suatu proses antrian adalah suatu proses yang berhubungan dengan kedatangan seorang pelanggan pada suatu fasilitas pelayanan, kemudian menunggu dalam suatu baris (antrian) jika pelayanannya sibuk dan akhirnya meninggalkan fasilitas tersebut setelah dilayani. Penelitian ini menghasilkan sistem antrian dengan metode FIFO (First In First Out) dengan menggunakan c++. Dari data ini dapat dilihat bahwa pelayanannya sangat cepat dan tingkat kedatangan pelanggan sangat lambat.

Abstract

Male fertility has declined over the past two decades. The decrease is due to environmental factors, such as lifestyle habits that can affect the quality of a man's sperm. Artificial intelligence technology is currently developing as a methodology for health decision support systems. In the process of predicting infertility can be done by applying Machine Learning technology. This study focuses on comparing the Random Forest classification method with Decision Tree C4.5 to see the level of accuracy in predicting the success of infertility data classification. Data for the Fertility Dataset was obtained from the UCI Machine Learning Repository with a total of 100 data records, 10 attributes and 2 attribute classes, namely Normal and Altered. The parameters used are age, childhood diseases, accidents or trauma, surgical operations, alcohol consumption and smoking habits. Then evaluate the testing of the two methods, namely by using 10fold Cross Validation. Based on the results of Random Forest and Decision Tree C4.5 testing, the average accuracy of Random Forest is 87.20% and Decision Tree C4.5 with an accuracy rate of 85.90%. From the results obtained, it can be concluded that Random Forest is a superior method by 1.3% when compared to Decision Tree C4.5 in predicting accuracy in the Fertility Dataset.

Abstract

The rapid development of e-commerce has generated huge volumes of data, opening up opportunities to analyze product demand patterns more accurately. This research aims to develop a product demand prediction model based on big data analysis. The data used includes sales transactions, product searches, customer reviews, and external factors such as seasons and promotions. The main methods used are machine learning techniques such as random forest regression and neural networks to build predictive models, with data extraction, transformation, and analysis processes carried out using big data platforms such as Hadoop and Spark. The resulting model is evaluated using accuracy metrics, such as mean absolute error (MAE) and root mean square error (RMSE), to measure prediction performance. The results show that the use of big data in product demand prediction can increase the accuracy of inventory planning and stock management by up to 25% compared to conventional methods. These findings make a significant contribution to the optimization of e-commerce operations, especially in more efficient and timely data-driven decision-making.

Abstract

Lung cancer is one of the three deadliest diseases in the world and has rapidly developed. Based on this, researchers conducted research to predict the factors that influence lung cancer. One method to identify this is using data mining methods and classification techniques. Researchers used several popular algorithms in classification to make comparisons of the most accurate algorithms for lung cancer classification. The algorithms used include K-Nearest Neighbor, Random Forest Classifier, Logistic Regression, Linear SVM, Naïve Bayes, Decision Tree, Random Forest, Gradient Boosting, Kernel SVM, and MLPClassifier. The researcher used this algorithm because, in the research that the researcher found on the Kaggle platform, he examined the comparison of the algorithm using the breast cancer dataset. In previous studies, their researchers used SVM, which obtained an accuracy of 96.47%, Neural Networks of 97.06%, and Naïve Bayes with an accuracy of 91.18% to study breast cancer. The difference from previous research is that this study uses several existing algorithms in Machine Learning such as K-Nearest Neighbor, Random Forest Classifier, Logistic Regression, Linear SVM, Naïve Bayes, Decision Tree, Random Forest, Gradient Boosting, Kernel SVM, and MLPClassifier. In addition, this research was conducted to see whether the results of the accuracy of the algorithm that the researchers carried out using the lung cancer dataset had different results. The results of this study found that the more accurate algorithms were Random Forest and Gradient Boosting with an accuracy value of 100%, whereas in previous studies, it was the same. Still, Gradient Boosting had a higher accuracy value than Random Forest. Then, based on the data used in this study, the most influencing factors in predicting a diagnosis of lung cancer are obesity and coughing up blood. The results of this study found that the more accurate algorithms were Random Forest and Gradient Boosting with an accuracy value of 100%, whereas in previous studies, it was the same. Still, Gradient Boosting had a higher accuracy value than Random Forest.
