Implementasi Data Mining Dengan Metode Regresi Linear Berganda Untuk Memprediksi Data Persediaan Buku Pada Pt. Yudhistira Ghalia Indonesia Area Sumatera Utara
Abstract:PT. Yudhistira Ghalia North Sumatra. Where Inventory (stock) of goods is an important thing in a company for data collection or checking activities in order to find out the amount of goods that are used up and goods that will be needed in a company. Inventory of goods is always needed in company activities. So that in the supply of books has been delayed for making stock and excess stock making of books. In this study, multiple linear regression method will be used to predict book inventory data. So for that w… Show more
“…Multiple linear regression technique is used to determine whether there is a significant impact of two or more independent variables (X1, X2, X3, .., Xk) on the dependent or independent variables (Y). (Gaol et al, 2019). In this study the method used is the survey method, according to (Sugiyono., 2018) survey research is research conducted on large and small populations, but the data studied are data from samples taken from the population, to find relative events, distribution and relationships between variables.…”

“…Dikti disetiap tahun nya. data mining ialah analisa atau pengamatan data dengan jumlah yang besar untuk menemukan hubungan yang belum diketahui sebelumnya, dan dua metode baru guna meringkas data supaya lebih mudah dimengerti serta kegunaannya untuk pemilih data [1], [2]. Analisis yang memiliki variabel bebas lebih dari satu disebut analisis regresi linier.…”
Proses penerimaan mahasiswa baru dilakukan setiap tahun akademik dengan tahapan seleksi yang telah ditetapkan perguruan tinggi guna memperoleh jumlah mahasiswa dan kualitas mahasiswa baru yang diharapkan perguruan tinggi .Selama ini di STMIK Bina Nusantara Jaya Lubuklinggau belum memiliki sistem yang dapat memprediksi jumlah mahasiswa baru pada periode akan datang. Salah satu solusi yang diperlukan adalah penerapan data mining dengan algortima regresi linear berganda untuk dapat memprediksi jumlah mahasiswa baru pada tahun yang akan datang. Variabel yang digunakan terdiri dari 3 variabel yaitu biaya, pendaftar dan mahasiswa baru dimana variabel diperoleh berdasarkan hasil uji validitas terhadap banyak variabel. Kemudian dilakukan analisa dengan algoritma regresi linear berganda diperoleh hasil prediksi mahasiswa baru pada tahun 2023 sebesar 38 orang, kemudian diuji dengan aplikasi pengujian menggunakan Ravidminer 5.0. dimana hasil prediksi mahasiswa baru pada tahun 2023 sebesar 38 orang.
“…Regresi merupakan suatu hubungan yang menentukan variabel terikat dengan variabel bebas (Prasetyo et al, 2021). Algoritma linear regression berganda merupakan algoritma yang memiliki variabel lebih dari satu (Gaol et al, 2019).…”
According to WHO, diabetes is a metabolic disorder characterized by high levels of sugar in the blood. Diabetes is a deadly disease if the sufferer cannot control it and it will become a complication. Many people are affected by diabetes and find out too late, so that at the time of treatment the condition has complications. Early detection of diabetes is very helpful for sufferers to avoid complications that will occur. Therefore we need a data mining technique that can process data and prevent diabetes from an early age. Data mining is a process of extracting knowledge from a number of data to find a pattern. Data mining has been widely used, one of which is the prediction method to find out people with diabetes. There are so many prediction methods available, one of which is linear regression, where this method uses dependent and independent attributes. In this study, the multiple linear regression method is used to predict diabetes, and evaluates using RMSE (root mean square error). The results of this study produce an RMSE value of 0.403, the RMSE test uses cross validation by changing the number of validation value
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
