Comparison of the performance results of c4.5 and random forest algorithm in data mining to predict childbirth process Muhasshanah Muhasshanah, Mohammad Tohir, Dewi Andariya Ningsih, Neny Yuli Susanti, Astik Umiyah, et al. Commit Journal, 2023 Technology advancements in the world of information have made it easier for many people to process data. Data mining is a process of mining more valuable information from large data sets. The research aims to determine the difference between the C.45 and random forest algorithms in data mining to predict the childbirth process of pregnant women. It compares the accuracy of the performance results of the C4.5 and random forest algorithms to predict the delivery process for pregnant women. Then, experimental research is conducted to classify the childbirth process in Situbondo, Indonesia, by applying the C.45 and the random forest algorithm in the data mining. The decision tree J48 algorithm is used for the C4.5 algorithm in the research. Both algorithms are compared for their error classification and accuracy level. The research uses 1,000 data for training and 200 data for testing. The results show the accuracy of implementing the C4.5 and random forest algorithms with data mining using 10-fold cross-validation, generating 96% and 95% as correctly classified data. Then, the Relative Absolute Error for both algorithms has the same result. It is 15%. The C4.5 algorithm has a better result than the random forest algorithm by comparing the performance results. Further research can add more data to improve the accuracy of the analysis results by using another algorithm.
Nineth grade students mistakes when solving congruence and similarity problem T T Wijaya, I I Mutmainah, N Suryani, D Azizah, A Fitri, et al. Journal of Physics Conference Series, 2021 This research aims to know the difficulty level and the difficulties faced by students on congruent and similar problems. The test is taken from students’ mid-semester exam in march 2021. Students’ learning condition is under the coronavirus pandemic. This research uses a mix-method to process its data which are the qualitative and quantitative methods. The quantitative method is used to analyze the difficulty level and the qualitative method will explain the difficulties faced by students when solving congruent and similar problems. There are 9 questions given in this research that consists of 8 visual problems and one combined problem. The difficulties of the problems are four questions with easy difficulty and five questions with medium difficulty. The sample of this research is 61 9th grade students from SPMN 47, Bandung, Indonesia. The data is taken by using the google platform. The second data will be taken from teachers’ interview results following the analysis of students’ difficulties when solving congruent and similarity problems. The test result average is 64.77 and teachers’ interview result shows that the poor test result is because teachers are not prepared with the teaching condition during the coronavirus pandemic. A recommendation for teachers is that they can improve their ability by integrating technology in mathematics.
