Abstract

Kumon is a tutoring place that implements a level-based learning system customized to individual abilities, aims to optimize each individual's abilities and intelligence. With Kumon learning methods many students can learn at up-class level, low-class level, and equivalent class level. Determining the level of Kumon is usually seen in students when attending Kumon classes for approximately six months to one year. However, by looking at several aspects that affect the level of students such as learning motivation, learning interests, learning habits, and gender of students, the Naive Bayes Classifier approach will be easy and fast in predicting kumon level for students. From the research using confussion matrix test, the result show the accuracy value of 70%, class precision of 75% for up-class level, class precision of 100% for low-class level, class precision of 60% for the equivalent of class level, class recall of 100% for up-class level, class recall of 25% low-class level, and class recall of 100% equivalent to class level. As a result, it is possible to conclude that the Naïve Bayes Classifier Algorithm can be used to predict the classification of kumon levels. However, it is hoped that the next research will use other attributes in order to get a more accurate algorithm.

Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh store atmosphere dan kualitas pelayanan terhadap kepuasan pelanggan pada Toko Resik Laundry Tangerang Selatan. Metode yang digunakan adalah kuantitatif. Teknik pengambilan sampel menggunakan rumus slovin dan diperoleh sampel sebanyak 60 responden. Analisis data menggunakan uji validitas, uji reliabilitas, uji asumsi klasik, analisis regresi, koefisien korelasi, koefisien determinasi dan uji hipotesis. Hasil penelitian ini adalah store atmosphere berpengaruh signifikan terhadap kepuasan pelanggan dengan koefisien determinasi sebesar 64,2% dan uji hipotesis diperoleh thitung > ttabel atau 10,188 > 1,672. Kualitas pelayanan berpengaruh signifikan terhadap kepuasan pelanggan dengan nilai koefisien determinasi sebesar 90,8% dan uji hipotesis diperoleh thitung > ttabel atau 23,967 > 1,672. Store atmosphere dan kualitas pelayanan secara simultan berpengaruh terhadap kepuasan pelanggan dengan persamaan regresi Y = - 0.167 - 0.059X1 + 1.072X2. Nilai koefisien determinasi sebesar 90,9% sedangkan sisanya sebesar 9,1% dipengaruhi faktor lain. Uji hipotesis diperoleh nilai Fhitung > Ftabel atau 285,240 > 3,160.
