PERANCANGAN SISTEM PENGENDALIAN KUALITAS PRODUK ASAM SULFAT (STUDI KASUS: PT. XYZ)
ABSTRACT: PT. XYZ is a basic
chemical manufacturing company which produces sulphuric acid. Quality standard
are reffered to National Standard of Indonesia (SNI). PT. XYZ has certified the
use of SNI standard for sulphurid acid product quality. Quality control of
product is supervised by technician from PT. XYZ to ensure that only products
that meet acceptable standard of quality which may be delivered to customer in
order to ensure customer satisfaction. PT. XYZ establish product specifications
sulphuric acid in the production process with a concentration of at least
98,5%. Determination of sulphuric acids product specification targets are too
high from the referenced standard is loss and optimal quantity of product produced.
This study aims
to measure the
process capability and
product specifications of sulphuric
acid establishes the
right to increase
the quantity of
products. And then,
Designing an appropriate system to
control product quality sulphuric acid which has been determined. Determination
of the specifications made by processing the sulphuric acids inspection levels.
Processing data using analytical tools of quality control, histogram charts,
control charts, and a causal diagram. Result of the analysis
compared to the
quality control standard
established by BSN
through SNI 0030:2011. From the comparison of the data
will be used to set quality standard appropriate levels of sulphuric acid. Quality
control system design sulphuric acid starts from the selection of raw material
supplier, controlling during the setting process until the sulphuric acid
concentration through dilution water.
