  1. Rancangan acak lengkap faktorial Lay out percobaan Misal: Faktor A; 3 level (A, B, C) Faktor B: 3 level (10, 20, 30) Ulangan 4 kali : 1, 2, 3, 4

  2. Untuk mengobati ikan mas yang terkena Aeromonas hydrophylla, dilakukan pengujian pengobatan dengan kloramfenikol, hijau malakit, khlortetrasiklin dan formaldehid dengan konsentrasi 0,5 ppm, 1 ppm dan 1,5 ppm. Percobaan diulang 4 kali. Aeromonas hydrophylla diberikan sebanyak 1 x 10 6 koloni/ml. Setiap bak percobaan diisi 50 ekor ikan. Hasil yang diamati adalah banyaknya ikan yang hidup setelah pengobatan.

  3. Banyaknya ikan yang hidup setelah pengobatan

  4. Banyaknya ikan yang hidup setelah pengobatan

  5. Banyaknya ikan yang hidup setelah pengobatan

  6. Tabel 2 arah

  7. FK = 636 2 /48 = 8,437 JK Total = 212 + 192 + 202 + … + 172 – FK = 971 JK Perlakuan = 762 +472 + 282 + … + 592 / 4 – FK = 845 JK Galat = JK Total – JK Perlakuan = 971 – 845 = 126 JK Jenis = 1512 + 1792 + 1242 + 1892/(3x4) – FK = 197 JK Dosis = 2742+2152+1472/(4x4) – FK = 505 JK Jenis Dosis = JK Perlakuan – JK Jenis – JK Dosis = 143

  8. ANOVA

  9. BNT0.05 = t0.05(dbgalat)x √(2KTgalat/ulangan) = 2.029 x √ (2 x 3.5/4) = 2.029 x √ (1.75) = 2.029 x 1.323 = 2.68

  10. BNJ0.05 = q0.05(12,36) x √(KTgalat/ulangan = 4.96 x √ (3.5/4) = 4.96 x √ (0.875) = 4.96 x 0.935 = 4.64

  11. Uji jarak Duncan UJD = Jarak Duncan (R0.05(p;db galat) x √(KTgalat/ulangan)

  12. Uraian tiap perlakuan dan atau seandainya interaksi tidak nyata: Tabel 2 arah

  13. Untuk Jenis BNT0.05 = t0.05(dbgalat)x √((2KTgalat/(ulangan x taraf dosis)) = 2.029 x√ ( 2 x 3.5 / (4x3) ) = 2.029 x 0.76 = 1.54

  14. Untuk Dosis BNT0.05 = t0.05(dbgalat)x √((2KTgalat/(ulangan x taraf jenis)) = 2.029 x√ ( 2 x 3.5 / (4x4) ) = 2.029 x 0.6614 = 1.34
