    lambat Jumat , 21 Desember 2014 Jam 12.00.

    1. Design experiments to study the following situations. Select the orthogonal array and

    identify the column assignments. a. Two 2-level factors and an interaction between them. b. Six 2-level factors (A, B, C, D, etc.) and interaction AxC. c. Four 2-level factors (A, B, C and D) and two interactions AxB and CxD. d. Five 2-level factors (A, B, C, D and E) and two interactions AxB and BxC. e. Ten 2-level factors(A,B,C, etc.) and three interaction AxB, BxC and CxD. 2. Design an experiment to study four factors: A, B, C, & D (2-Levels each) and

    interactions BxC AND BxD. Can an L8 be used. If so, assign factors and interaction to the appropriate columns.

    3. Ina seito tile experiment

    1950 problem with variability in dimension More than 50% outside specification Problem with kiln Redesign kiln expensive Use parameter design Seven factors were studied ( 2 level )

    Factor Level 1 Level 2

    A Lime content 5% 1%

    B Granularity coarse fine

    C Agalmatolite 43% 53%

    D Agalmatolite Type current mixture cheaper mixture

    E Charge equity 1300 kg 1200 kg

    F Waste return 0% 4%

    G Feldspar content 0% 55%

    R1,R2,R3 and R3 defect per 100 unit

    4. Diketahui hasil eksperimen menggunakan OA yang dimodifikasi menggunakan cara

    dummy level design sebagai berikut :

    Exp A B C D R1 R2 R3 R4 1 1 1 1 1 16 18 12 14 2 1 2 2 2 17 18 20 16 3 1 3 3 3 12 10 13 11 4 2 1 2 3 6 8 5 6 5 2 2 3 1 6 8 7 5 6 2 3 1 2 68 50 45 70 7 1 1 3 2 42 35 40 45 8 1 2 1 3 40 35 42 44 9 1 3 2 1

    R1,R2,R3 and R3 defect per 100 unit

    Lakukanlah anilisis hasil eksperimen diatas. Apa hasil kesimpulannya ?

    R1 tanggal lahir anda R2 terakhir tanggal lahir anda - 3 R3 terakhir tanggal lahir anda + 3 R4 terakhir tanggal lahir anda + 5

    R1 Dua digit terakhir NIM Anda R2 Dua digit terakhir NIM Anda - 2 R3 Dua digit terakhir NIM Anda + 2 R4 Dua digit terakhir NIM Anda + 5

    Untuk mahasiswa yang dua digit terakhir NIM 1 10 berubah menjadi dua digit terakhir NIM + 5 , contoh 1 menjadi 6 , dst

  • 5. Dalam sebuah eksperimen diketahui faktor-faktornya adalah sebagai berikut : A : Temperatur B : Waktu C : Metoda pencucian C1 dengan larutan asam dan C2 dengan air D : Konsentrasi larutan asam ( nested factor ) E : Konsentrasi air ( nested factor ) Hasil eksperimen adalah sebagai berikut :

    No. 1 2 3 4 5 6 7
