Abstract

Abstrak. Bagan kendali Shewhart terdiri dari dua macam bagan kendali yaitu bagan
kendali variabel dan bagan kendali atribut. Bagan kendali variabel dibedakan atas tiga
bagan kendali yaitu bagan kendali I MR;

X R;

X S.Bagan kendali Robust adalah
bagan kendali yang tahan terhadap data pencilan. Penduga yang digunakan pada bagan
kendali Robust adalah penduga Hodges-Lehman dan penduga Shamos-Bickel-Lehman.
Pada penelitian kali ini, sebagai aplikasi yang diterapkan untuk membuat bagan kendali
proses pengukuran berat semen, menggunakan metode bagan kendali Shewhart (bagan
kendali

X  R) dan bagan kendali Robust. Proses pengukuran berat semen adalah ke-
masan 50kg yang diproduksi oleh PT. Semen Padang. Proses yang terjadi menurut kedua
bagan kendali adalah out of control.
