PENENTUAN SETTING LEVEL OPTIMAL PADA PEMANFAATAN ABU SEKAM PADI UNTUK MENINGKATKAN KUALITAS PAVING BLOCK MENGGUNAKAN METODE EKSPERIMEN TAGUCHI
Abstract: Paving block is one
of construction material elements that is now widely used by the society. The
quality improvement of paving block product should be conducted continuously to
avoid the product defect. The defect usually occurring in paving block includes
the surface fracture and fissure. The common way conducted to improve the
quality of paving block was to add the amount of cement into the material mix.
But this may result in the higher cost of raw material. For that reason, it was
used another alternative material whose function is similar to the cement’s. In
this research the alternative material added was the rice husk ash. The
characteristics of quality that will be optimized to improve the quality of
paving block are the compressive strength and percentage of water absorption.
Both characteristics were optimized simultaneously. In order to test those two
characteristics the Taguchi experiment was conducted.
The approach used in processing data was to combine the experiment design
from Taguchi method, regression model and optimization of total quality loss
function using non-linear programming model. The data processing was conducted
to obtain the optimum setting level. The optimum setting level was the
combination of level providing the number of minimum quality loss function.
