Abstract

Penelitian ini dilakukan untuk mengetahui defect apa saja yang sering muncul pada proses injection dan kombinasi item defect apa saja yang sering terjadi, untuk melakukan pengendalian kualitas produk yang bersangkutan. Metode analisis yang digunakan adalah analisis kuantitatif dengan menggunakan metode algoritma apriori yang dapat mengelola nilai input yang sesuai dengan kriteria-kriteria pada item yang mempunyai nilai support dan confidence tertentu dengan perhitungan RapidMiner. Algoritma apriori merupakan salah satu algoritma dalam data mining yang dapat digunakan dalam association rule untuk menentukan frequent itemset yang berfungsi untuk membantu menemukan pola dalam sebuah data. Dengan menggunakan algoritma apriori, dapat menghasilkan pola kombinasi sebanyak 17(tujuh belas) rules dengan nilai support sebesar 70% dan nilai confidence tertinggi dari 17(tujuh belas) rules tersebut sebesar 93% yang terdapat dalam rule Lock Broken → Disscolour.

Abstract

The purpose of this study was to determine the effect of working capital-to-total assets, debt-to-equity ratio, total asset turnover, and operating profit margin on profit growth. The population used are mining companies listed in the Indonesia Stock Exchange 2017-2021 period which amounts as much 53 companies. The sampling technique used is purposive sampling and obtained by amount as much 37 companies multiplied by 5 years, so the total sample amount as much 185 companies. The analysis technique used is multiple linear regression analysis with SPSS Version 24. The hypothesis test uses the t-statistic level of significance of 5%. The result shows that: WCTA has a negative and significant effect on growth profit, so H1 is rejected and H0 is accepted. DER has a negative and significant effect on growth profit, so H2 is accepted and H0 is rejected. TATO and OPM have positive and significant effects on growth profit, so H3 and H4 are accepted and H0 is rejected. Based on the value adjusted R2, it shows that the contribution of variable WCTA, DER, TATO, and OPM can be explained by a growth profit is 0.604 or 60,4%. The remaining 0.396  or  39,6%  was caused by other variables which were not examined in this study.
