APLIKASI SIX SIGMA PADA PENGUJIAN KUALITAS PRODUK DI UKM KERIPIK APEL TINJAUAN DARI ASPEK PROSES
ABSTRACT: The objectives of
the research were to measure the capability of frying and spinning, to
calculate the sigma value in frying and spinning, and to analyze the factors
causing the unsuitability of chips form to specification, and to recommend
quality improvement at chips industry.
Descriptive research was used with six sigma approach. The quantity of
samples was 100 units in 20 observations.
The stages of this research were defining (determining CTQ), measuring
(measuring the process capability and calculating sigma value), and analyzing
(analyzing the defect cause) stages. In
defining stage, the product defect in crushed chips after spinning was
32.5%. In measuring stages, the process
capability measurement obtained Cp (process potential index) of 0.64 and Ppk
(process capability index) value of 0.49, and sigma value of 2.11. In analyzing stage based on fishbone diagram,
the causing factors of crushed chips were machine, man, and method.
Recommendation to reduce defect was by periodically worker evaluation, SOP, and
re-analysis the maintenance schedule.
