Judul: Feeding Fermented Fish Waste Meal in Rations on the Physical Quality of Quail Eggs
Abstrak: Penelitian ini bertujuan mengevaluasi pengaruh pemberian tepung limbah ikan fermentasi dalam ransum terhadap kualitas fisik telur puyuh. Penelitian ini menggunakan 160 ekor puyuh betina berumur 25 minggu yang dipelihara selama 8 minggu. Dipelihara menggunakan kandang koloni bertingkat dengan rancangan acak lengkap (RAL) terdiri dari 4 perlakuan dan 4 ulangan. P0 = ransum kontrol, P1= ransum mengandung 2% tepung limbah ikan fermentasi, P2 = ransum mengandung 4% tepung limbah ikan fermentasi, P3 = ransum mengandung 6% tepung limbah ikan fermentasi. Peubah yang diamati adalah kualitas fisik telur yang meliputi bobot telur, indeks telur, tebal kerabang, persentase bobot kerabang, persentase bobot putih, persentase bobot kuning, warna kuning, dan haugh unit telur. Hasil penelitian menunjukkan bahwa pemberian tepung limbah ikan fermentasi sebanyak 2%, 4%, dan 6% dalam ransum tidak berpengaruh nyata (P>0,05) terhadap nilai bobot telur, indeks telur, tebal kerabang, persentase bobot kerabang, persentase bobot putih, persentase bobot kuning, warna kuning, dan haugh unit telur puyuh. Dapat disimpulkan bahwa pemberian tepung limbah ikan fermentasi sampai level 6% dalam ransum tidak memengaruhi kualitas fisik telur puyuh dan masuk kedalam kisaran normal telur puyuh. Tepung limbah ikan fermentasi ini dapat digunakan sebagai bahan pakan substitusi tepung ikan komersil., This study aimed to evaluate the effect of feeding fermented fish waste meal in the diet on the physical quality of quail eggs. This study used 160 female quails aged 25 weeks that were reared for 8 weeks. Maintained using multilevel colony cages with a completely randomized design (CRD) consisting of 4 treatments and 4 replicates. P0 = control ration, P1 = ration containing 2% fermented fish waste meal, P2 = ration containing 4% fermented fish waste meal, P3 = ration containing 6% fermented fish waste meal. The observed variables were the physical quality of eggs which included egg weight, egg index, shell thickness, shell weight percentage, white weight percentage, yellow weight percentage, yellow color, and haugh unit of eggs. The results showed that feeding fermented fish waste meal as much as 2%, 4%, and 6% in the ration had no significant effect (P>0.05) on the value ofegg weight, egg index, shell thickness, shell weight percentage, white weight percentage, yellow weight percentage, yellow color, and haugh unit of quail eggs. It can be concluded that feeding fermented fish waste meal up to 6% level in the ration does not affect the physical quality of quail eggs and is within the normal range of quail eggs. Fermented fish waste meal can be used as a substitute feed ingredient for commercial fish meal.

Judul: Supplementation of Vitamin D3 in the
Diet on Egg Quality of Quail (Coturnix coturnix japonica).
Abstrak: Penelitian ini bertujuan untuk mengetahui efektivitas pemberian ransum yang disuplementasi vitamin D3 terhadap kualitas fisik telur puyuh. Percobaan dilakukan pada ternak puyuh yang berusia 22 minggu dan dipelihara sampai umur 27 minggu dengan jumlah 450 ekor. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas 3 perlakuan dan 5 ulangan yaitu P0: Ransum tanpa suplementasi vitamin D3 (ransum kontrol), P1: P0 suplementasi vitamin D3 1,0 g kg-1, P2: P0 suplementasi vitamin D3 1,5 g kg-1. Data dianalisis menggunakan Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Duncan bila berbeda nyata. Hasil penelitian menunjukkan bahwa penambahan vitamin D3 dalam pakan sangat nyata (P, This study aimed to determine the effectiveness of feeding diets supplemented with vitamin D3 on the physical quality of quail eggs. The experiment was carried out using quail aged from 22 weeks and reared until the age of 27 weeks with a total of 450 quails. The research method used a completely randomized design (CRD) consisting of 3 treatments and 5 replications, namely P0: diet without vitamin D3, P1: P0 vitamin D3 1.0 g kg-1, P2: P0 vitamin D3 1.5 g kg-1. Data were analyzed using Analysis of Variance (ANOVA) and followed by Duncan’s test if they were significantly different. The result showed that the addition of vitamin D

Judul: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
