Judul: Ripitabilitas Sifat Kecepatan Lari dan Korelasi Fenotipiknya dengan Tinggi Badan pada Kuda Pacu Indonesia
Abstrak: Kuda Pacu Indonesia merupakan hasil grading-up kuda Sumba dengan kuda pacu Thoroughbred, membentuk ”bangsa baru” yang telah beradaptasi baik dengan lingkungan Indonesia sehingga dianggap sebagai kuda lokal. Kuda tersebut memiliki potensi untuk dikembangkan. Salah satu parameter genetik yang diperlukan untuk program seleksi sifat kecepatan lari adalah ripitabilitas. Penelitian ini diperlukan sebagai dasar pengembangan Kuda Pacu Indonesia (KPI). Perolehan informasi kecepatan lari sebagai data penelitian dilakukan dari koleksi data pada Buku Panduan Acara Kejurnas Pordasi tahun 1998–2008. Data yang diperoleh merupakan data performa fenotipik kuda pacu yang dilombakan. Data yang diolah merupakan kecepatan lari, yang diperoleh dari informasi waktu tempuh dan jarak lomba, dan tinggi badan. Setiap individu kuda yang diamati memiliki jumlah catatan yang tidak sama satu sama lain. Data dari individu-individu kuda yang diamati dikelompokkan berdasarkan jenis kelamin dan umur. Perhitungan ripitabilitas kecepatan lari dilakukan berdasarkan Becker (1968) dengan model statistik Yik = μ + αi +eik. Perhitungan nilai korelasi dilakukan dengan rumus korelasi regresi. Kecepatan lari KPI jantan dan betina pada umur dua tahun berbeda (P<0,05), berturut-turut sebesar 15,030±0,724 dan 15,203±0,634 m/detik. Kecepatan lari kuda pacu jantan dan betina tidak berbeda pada umur 3, 4, dan >4 tahun; berturut-turut sebesar 15,096±0,514; 15,244±0,704; dan 15,308±0,758 m/detik.

Judul: Ripitabilitas sifat kemampuan kuda pacu Indonesia mempertahankan kecepatan berlari
Abstrak: Indonesia racehorse is a domestic animal results of grading up between local mares with Thoroughbred stallion to get a better Indonesia racehorse. Selection of running performance racehorse in Indonesia needs to be done in order to get a racehorse that has good running ability. Performance of Indonesia Racehorse can be estimated by the running speed and ability to maintain these properties. The value of ability to maintain the running speed data used to estimate the ripitability value. The data of running speed at different distances (1200 m, 1400 m, and 1600 m) in each race which was obtained from racing record in PORDASI (Persatuan Olahraga Berkuda Seluruh Indonesia) competition for twelve years, were used to calculated the value of ability to maintain a running speed. Estimated ripitability value used to calculate the value of MPPA (Most Probable Producing Ability). Estimated ripitability of ability to maintain a running speed horse which ran at decreased speed and increased speed are 0,7714 ± 0,0988 and 0,3421 ± 0,2789, respectively. Indonesia Racehorse which has speed decreased could be recommended for sprint type horse while the increased speed horses could be recommended as long distance horse type.

Judul: Synthesis of Molybdenum Trioxide (MoO3) by Electrochemical Method for Electrochromics Application
Abstrak: Molybdenum trioxide (MoO3) thin films have been deposited on glass substrates by electrochemical method using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O). The films were deposited onto glass substrates as the control temperature at 25○C and annealing treatment at 350○C for 30 mins. The MoO3 thin films were investigated by UV-Vis, X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM). The JCPDS card show that orthorhombic MoO3 (α- phase) has been formed. Molybdenum trioxide MoO3 formation was also confirmed by JCPDS card no. 35-0609. The SEM photographs revealed that the spherical and rod-like morphology and their grains size increased with increasing of heating temperatures. The measurement results show that the MoO3 thin film prepared at 350°C transmited about 80% of the visible spectrum. The effect of different heat treatments on surface morphology, thickness and optical properties of the films are discussed in this thesis.
