| Summary: | PT Semen Padang is one of the first cement producers in Southeast Asia
and has been operating for more than 110 years. Therefore, PT Semen Padang tries
to make various innovations by developing interlock brick products by reason of
the housing developer's need for fast, easy, and quality development as well as
customer needs for affordable homes. Interlock brick is also had various
advantages over red bricks, especially in terms of cost savings and environmental
friendliness. PT Semen Padang now is developing interlock brick products to
conform to the standard. The development process of PT Semen Padang's interlock
bricks has reached the stage of making a prototype model house. The existing
interlock brick products of PT Semen Padang have not been adjusted to the physical
parameters of SNI 03-0349-1988 based on discussions with the production party of
PT Semen Padang interlock bricks. Therefore, this research was conducted to find
the best product parameter of PT Semen Padang interlock brick products based on
the physical parameters of SNI 03-0349-1989.
The search for the best composition of interlock bricks was carried out using
the Taguchi experiment. Taguchi's experimental method consisted of three groups
of stages. The first group of stages is pre-experiment, which aims at experimental
factors and responses and making experimental combinations with orthogonal
matrixes. The second stage group is an experiment in the form of a process of
calculating the experimental response. The third stage group is post-experimental
in the form of data processing by finding the optimal value of each factor in each
experimental response.
Based on the study's results, it was found that the optimum level
combination for compressive strength parameters based on SNI 03-0349-1989 is a
material ratio of 1:4, the percentage of water is 3%, and the type of material is
cement (1) + mixed sand (4). The optimum level combination for water absorption
parameters based on SNI 03-0349-1989 is a material ratio of 1:4, the percentage
of water is 1%, and the type of material is cement (1) + mixed sand (4).
