Performance Analysis of Classification and Regression Tree (CART) Algorithm in Classifying Male Fertility Levels with Mobile-Based

Fertility is the ability to produce offspring in a man or the ability of the reproductive organs to work optimally in fertilization. Fertility rates have declined drastically in the last fifty years. Machine Learning is a field devoted to understanding and building learning methods. This study will use machine learning algorithms to classify male fertility levels, namely the Classification and Regression Tree (CART) algorithm and the K-Fold Cross Validation validation method. The fertility dataset used in this study was obtained from the UCI Machine Learning website, with a total of 100 data and the variables used are Age, Childish diseases, Accident or serious trauma, Surgical intervention, High fevers in the last year, Frequency of alcohol consumption, Smoking habit, Number of hours spent sitting per day and Diagnosis. K-Fold Cross Validation can be used together with CART to measure the performance of the CART model on different data, so as to avoid overfitting or underfitting the CART model. Based on the calculation of the CART algorithm and the K-Fold Cross Validation validation method (K = 1 to K = 9), the average accuracy value for training data is 98.70% and the average accuracy value for testing data is 81.16%. The results of this study have proven that the CART algorithm can be used to classify the level of fertility in men well. In addition, the classification model formed can be implemented into a mobile application (android) so that it is easy to use and understand.Fertility merupakan kemampuan untuk menghasilkan keturunan pada seorang laki-laki atau kemampuan alat reproduksi untuk bekerja secara optimal dalam melakukan pembuahan. Angka fertility telah menurun secara drastis dalam lima puluh tahun terakhir. Machine Learning merupakan bidang yang dikhususkan untuk memahami dan membangun metode pembelajaran. Dalam penelitian ini akan menggunakan algoritma machine learning untuk mengklasifikasikan tingkat kesuburan pria yaitu algoritma Classification and Regression Tree (CART) dan metode validasi K-Fold Cross Validation. Adapun dataset fertility yang digunakan dalam penelitian ini diperoleh dari situs UCI Machine Learning, dengan jumlah data sebanyak 100 dan variabel yang digunakan yaitu Age, Childish diseases, Accident or serious trauma, Surgical intervention, High fevers in the last year, Frequency of alcohol consumption, Smoking habit, Number of hours spent sitting per day dan Diagnosis. K-Fold Cross Validation dapat digunakan bersama dengan CART untuk mengukur performa model CART pada data yang berbeda-beda, sehingga dapat menghindari overfitting atau underfitting pada model CART. Berdasarkan perhitungan algoritma CART  dan metode validasi K-Fold Cross Validation (K=1 sampai dengan K=9) diperoleh nilai rerata akurasi untuk data training sebesar 98,70% dan rerata akurasi untuk data testing diperoleh nilai rata-rata akurasi sebesar 81,16%. Hasil penelitian ini telah membuktikan bahwa algoritma CART dapat digunakan untuk mengklasifikasikan tingkat kesuburan pada pria dengan baik. Selain itu, model klasifikasi yang terbentuk dapat diimplementasikan ke dalam sebuah aplikasi mobile (android) sehingga mudah untuk digunakan dan dipahami

Implementation of Random Forest Algorithm on Palm Oil Price Data

One of the potential commodities that are widely cultivated in Indonesia is palm oil, and palm oil or commonly referred to as palm oil is one of the processed products of palm oil which generates the most important foreign exchange for Indonesia. Data mining is a process that utilizes mathematical techniques, statistics, artificial intelligence, and machine learning techniques to extract and identify useful information and related knowledge from large databases [3], including palm oil price data. Random Forest is one of the methods in the decision tree. A decision tree is a flowchart shaped like a tree with a root node that is used to collect data that is used to solve problems and make decisions. In this study, a random forest algorithm was used to classify palm oil price data from 2014 to 2019. The classification method used the random forest algorithm on palm oil data using the Mtry parameter of 1 and the Ntree parameter of 500 resulting in an accuracy percentage of 100%. The most influential variable (importance variable) in the classification model using the resulting random forest algorithm is the palm oil variable
