Judul: Relationship between Goodness-of-Fit of Gabriel and Procrustes Analysis in Logratio Biplot Analysis.
Abstrak: Biplot lograsio merupakan adaptasi dari biplot biasa dengan melakukan transformasi logaritmik dan pemusatan ganda. Analisis biplot lograsio ini diterapkan pada data khusus yang terdiri atas vektor-vektor baris dengan elemen-elemen positif dengan kendala jumlah 100%, yang dikenal dengan data komposisi. Dari biplot lograsio, diperoleh tiga pendekatan matriks yang terkait dengan data, peubah, dan objek. Ukuran kesesuaian dari ketiga matriks tersebut telah dikemukakan oleh Gabriel pada tahun 2002. Studi ini bertujuan untuk menelusuri keterkaitan antara ukuran kesesuaian yang telah dikemukakan Gabriel dengan ukuran kesesuaian yang diperoleh dari analisis Procrustes. Untuk mendapatkan ukuran kesesuaian analisis Procrustes dengan menentukan nilai perbedaan minimum, dilakukan tiga transformasi geometri yaitu translasi, rotasi, dan dilasi. Dalam biplot lograsio, untuk mendapatkan ukuran kesesuaian bagi pendekatan matriks data, peubah, dan objek, hanya perlu dilakukan transformasi dilasi dalam analisis Procrustes. Oleh sebab itu, ukuran kesesuaian yang diperoleh dari analisis Procrustes nilainya akan sama dengan ukuran kesesuaian Gabriel. Ukuran kesesuaian untuk matriks pendekatan peubah dengan suatu nilai akan memiliki nilai yang sama dengan matriks pendekatan objek dengan nilai . Matriks pendekatan data, peubah, dan objek akan memiliki ukuran kesesuaian yang sama pada saat nilai .

Judul: The Relation of Gabriel’s Goodness of Fit with Procrustes Analysis in Biplot Analysis
Abstrak: The goodness of fit in biplot analysis related to data, object, and variable matrix was presented by Gabriel in 2002. Procrustes analysis is one way that can be used to determine the value of goodness of fit through three kinds of transformations, namely translation, rotation, and dilation. The translation and rotation in Procrustes analysis are not necessary in the data and object matrix, thus the only transformation needed in Procrustes analysis is dilation, which gives the same results as the goodness of fit in biplot analysis presented by Gabriel. In the variable matrix, all three transformations in Procrustes analysis need to be done. Thus, the goodness of fit obtained through the Procrustes analysis is always greater than or equal to the goodness of fit in biplot analysis presented by Gabriel.

Judul: Manajemen Pemeliharaan Kuda (Equus caballus) Untuk Upacara Kenegaraan Dan Sarana Kesenjataan Di Detasemen Kavaleri Berkuda (DenKavkud) TNI-AD Parongpong
Abstrak: Cavalry Horse Detachement (Denkavkud) Indonesian National Army-Cavalary Parongpong is one of the Indonesian military units that utilize the horse and train it as a means of purpose of formal state ceremony and armed forces. Skills possessed by the horse cavalry was the result of care management and specialized training provided by the trainer. Aspects of care management are breeding, feeding, and management. Horses that are kept in the Denkavkud, Parongpong are stallions, mares, foals, and military horses. Total populations of horses at Denkavkud are 183 horses. Besides commited horse training (remonte), Denkavkud also did breeding program to produce horses that can be trained and used as a military horse. There are some issues contained in Denkavkud, such as some of the nutrients needed by the horses not being met from feed given. One of these is crude protein and lysine. Lactation mares was crude protein and lysine deficiency. The number of death in 2010 is higher than previous years. Based on the number of horses that died from January until June 2010 is 11 horses. The average mortality was caused by colic. Colic is caused by excessive eating, excessive drinking during hot, moldy food, and even by investment roundworms. Animal welfare in Denkavkud can be enhanced by improvement of feed given and improving the health of livestock through improved sanitation.
