1 Control Chart fo Attribute

2 c-Chart untuk jumlah jenis cacat (n konstan) No Standard Given Cl c = c UCL c = c + 3 √ c UCL c = c - 3 √ c Standard Given Cl c = c o UCL c = c o + 3 √ c o UCL c = c o - 3 √ c o

3 Sampel number Numb. Of nonconformities Sampel number Numb of nonconformities Total189 CLc = 189/25 = UCLc = √ = LCLc = – 3 √ =  0 Setelah data no 9 dikoreksi CLc = (189-16) /24 = UCLc = √ = LCLc = 7.208– 3 √ 7.208=  0

4 u-Chart untuk memetakan jumlah cacat dalam per unit Jika ukuran sub grup konstan (n konstan) sampel = i jumlah cacat per unit = ui ui = ci/n u = UCLu/LCLu = u + 3 u/n ∑ i=1 g ci n g Jika ukuran sub group bervariasi ui = ci / ni ∑ i=1 g ci ni u = ∑ i=1 g UCLu/LCLu = u + 3 u/ni

5 Sample number Amount of inspected in m2 Numb. Of non conformities ci Sample number Amount of inspected in m2 Numb. Of non conformities ci Total Bangun bagan kendali bagi jumlah cacat dalam 100m 2

6 Sample number Amount of inspected in m2 Numb. Of non conformities Per 100m2 ui 6.4Sample n6umber 4 Amount of inspected in m2 Numb. Of non conformities Per 100m2 ui Total41 u = 192 / 41 = UCL/LCL = √ 4.683/2 = dan 0.092
