Perancangan Eksperimen untuk Meningkatkan Kualitas Ketangguhan Material dengan Pendekatan Analisis General Factorial Design (Studi Kasus: Produk Solid Surface)

Abstract

PT WLS is a company that produce solid surface product. The variance of shape and design that can
be produced is very high and can be customized to the demand. The problem that occur in this company is
that sometimes the product fractured during delivery and production. To cope this problem, an experiment
design with General Factorial Design is used to determine the best material composition that can increase the
toughness of the material. Two factors are determined to be the main factors that determine the toughness
of the materials which is the amount of hardener and the type of material used. Charpy test was used to
determine the toughness of the samples with a 55 mm x 10 mm x 10 mm dimension. Based on the analysis
done, the amount of catalyst, the type of material used, and the interaction between those two factors have a
significant effect to the materials toughness value and to get the optimal result for a 100 mm x 100 mm x 9
mm sample, it was advised to use 3 ml of hardener and Al(OH)3 with HWF specifications.
