ANALISIS PERUBAHAN SIFAT MEKANIS KEKUATAN TARIK DAN KEMULURAN MATERIAL PVC INSULATION 104 NATURAL DALAM PROSES PRODUKSI KABEL CU/PVC (NYA) 4 MM²

Abstract

This study aims to analyze the effect of the cable production process on the mechanical properties, namely tensile strength and elongation, of PVC 104 Natural Insulation material for CU/PVC (NYA) 4 mm² cables. As a preliminary step, a Shapiro-Wilk normality test was conducted on the difference data (setelah-sebelum) to validate the use of parametric statistical methods. The results showed that the difference data for both variables were normally distributed, allowing the analysis to proceed using a Paired T-Test at a significance level of  The t-test results indicated that the production process significantly increased the kuat tarik ( ) and significantly decreased the elongation ( ). This statistically valid conclusion indicates that the production process makes the Insulation material stronger but less flexible
