Judul: Identifikasi Morfometrik Kuda Pacu Di Indonesia Secara Citra Digital
Abstrak: Penelitian ini memberikan informasi mengenai perbandingan metode pengukuran citra digital dan manual pada pengukuran tinggi 19 ekor kuda dengan tingkat keakuratan yang dihasilkan. serta mengidentifikasi ukuran tubuh kuda pacu di Indonesia dilakukan pada kuda G1, G3, G4, KPI, dan THB pada selang umur 3-10 tahun dengan total kuda 44 ekor. Metode pengukuran secara citra digital tidak memberikan perbedaan nyata dengan pengukuran manual. Tingkat keakuratan pengukuran digital sebesar 98.34% dengan selang maksimal 1.27 cm. Keseluruhan parameter dianalisis dengan perangkat lunak ImageJ. Data perbandingan pengukuran manual dan digital dianalisis secara nonparametrik (uji Wilcoxon) dan ukuran tubuh diuji menggunakan Rancangan Acak Lengkap (RAL). Hasil yang diperoleh menunjukkan bahwa 9 peubah yakni panjang leher, scapulla, metacarpal, panjang badan, tinggi badan, tinggi pinggul, femur, tibia-fibulla, jarak fetlock-coronaria band memiliki perbedaan nyata antara ketiga kelompok kuda. Sementara 4 peubah lainnya yaitu humerus, radius-ulna, metatarsal, dan lebar dada tidak memiliki perbedaan antara jenis kuda yang diamati. Data rataan dari yang terkecil hingga terbesar antara 3 kelompok kuda adalah kelompok pertama kuda G1, kelompok kedua yang terdiri dari G3, G4, dan KPI, serta kelompok ketiga adalah kuda Thoroughbred.

Judul: Karakteristik ukuran dan bentuk tubuh kuda Sumba, Priangan, kuda pacu G2, G3, G4 dan kuda pacu Indonesia (KPI)
Abstrak: This research was carried out for two march to may 2006 in Pulo Emas, Jakarta. The horse used at this research is male and female that have reached body maturity and grouped based on breed of horses, five of G3 horses, five of G4 horses and for Indonesian racing horses. The data was analsed with Principle Component Analysis (PCA) to make diagram of crowd on each group of horses based on analogical of size and shape body that alighted from matrix covarians. The aim of this research is to study characteristic of size and shape body horse based on Principle Component Analysis (PCA) by measurement of wither height, hip height, body length, chest depth and the cannon circumference.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
