PENGARUH KUALITAS BAHAN BAKU, PROSES PRODUKSI DAN KUALITAS TENAGA KERJA TERHADAP KUALITAS PRODUK PADA PABRIK TAHU APL KEDUNGPRING LAMONGAN

Abstract

Operational management of production to achieve a series of activities or activities in creating, coordinating, regulating and managing systems by utilizing all available resources effectively and efficiently so as to produce goods or services.

This study aims to determine the effect of the variable quality of raw materials, production processes and labor quality partially, simultaneously and dominantly on product quality at the Kedungpring Lamongan APL Tofu Factory. This study uses quantitative research methods. The sampling technique used is the saturated sampling technique, namely by taking the entirety of the existing population. The number of samples in this study amounted to 56 respondents.

The tools used in this research use validity test, reliability test, classical assumption test, multiple linear regression, multiple correlation, coefficient of determination, while in hypothesis testing using t test and F test. X1 obtained tcount > ttable with a value of 2,497 > 2,006, t test X2 obtained tcount > ttable with a value of 4.032 > 2.006, and t-test X3 obtained tcount > ttable with a value of 2.705 > 2.006, while in the simultaneous test obtained Fcount > Ftable with a value of 31.407 > 2.78, and from the results of multiple linear regression, the results obtained are Y = 1.973 + 0.314 X1 + 0.552 X2 + 0.411 X3 in this case the production process variable in multiple linear regression testing is the most dominant.

From the results of the research above, it is found that the variables of the quality of raw materials, production processes and quality of labor, have a significant effect on product quality at the Kedungpring Lamongan APL Tofu Factory, and product quality variables have a dominant influence compared to the variables of raw material quality and labor quality on product quality at APL Kedungpring Lamongan Tofu Factory.
