Judul: Sintesis α-Fe2O3 menggunakan metode sol gel
Abstrak: In this reseach was succeeded make powder α-Fe2O3 with particle size 202.64 nm. Synthesis using Sol-Gel method with SiO2 coating derived from Si(OC2H5)4 at temperature of 750 oC for 5 hours. Characterization XRD prove that sample form is α-Fe2O3 (11 peaks) and β-Fe2O3 (2 peaks) with crystal size 20.69125 nm and crystallization 44 %. The cystal structure of α-Fe2O3 is rhombohedral and β-Fe2O3 is hexsagonal. Optic characterization show that the sample absorbing light at wavelength less than 480 nm. Bandgap energy of the optical characterization measurments is 2.74 eV.

Judul: Sintesis dan Karakterisasi Film BiFeO3 didadah Barium (II) Asetat (Ba(CH3COO)2).
Abstrak: Sintesis film BiFeO3 dengan pendadah Barium (II) Asetat (Ba(CH3COO)2), variasi konsentrasi pendadah yang digunakan 0%; 0,5%; 1%; dan 1,5% diatas substrat Si (100) tipe-p dibuat dengan metode chemical solution deposition (CSD) dengan teknik spin coating telah berhasil dilakukan. Proses annealing dimulai dari suhu ruang kemudian dinaikan hingga suhu annealing 850oC dengan kenaikan suhu 1.67oC/menit dan ditahan konstan selama 8 jam pada suhu annealing tersebut. Selanjtnya dilakukan proses pendinginan sampai kembali pada suhu kamar selama 12 jam. Menghitung ketebalan film yang dihasilkan dengan menggunakan metode volumetrik, ketebalan yang dihasilkan yaitu 1,667 μm, 1,9047 μm, 2,1164 μm, dan 2,3809 μm. Analisis data XRD dengan metode Cramer-Cohen menghasilkan nilai parameter kisi a=b sebesar 5,4247 Å, 5,4326 Å, 5,4993 Å, dan 5,5691 Å. Serta parameter kisi c yaitu 14,1241 Å, 14,1533 Å, 14,3525 Å, dan 14,5720 Å, dengan struktur kristal heksagonal. Nilai energi bandgap yang dihasilkan dari analisis dengan fungsi Kubelka Munk untuk indirect transition berada pada kisaran 2,6246 – 2,5751 eV., Synthesis of BiFeO3 film with Barium (II) Acetate (Ba(CH3COO)2), the concentration variation of the solvent used are 0%; 0.5%; 1%; and 1.5% above the p-type Si (100) substrate that are made by chemical solution deposition (CSD) method with spin coating technique has been successfully carried out. The annealing process is started from room temperature, it is increased to 850oC of annealing temperature with 1.67oC/minutes of temperature increase. It is constantly held for 8 hours at the annealing temperature. After that, the cooling process is carried out until the temperature returns to room temperature for 12 hours. The results of thickness film are calculated using the volumetric method, including 1.667 m, 1.9047 m, 2.1164 m, and 2.3809 m. The results of XRD data analysis is lattice parameter values a=b, which is using the Cramer-Cohen method; they are 5.4247, 5.4326, 5.4993, and 5.5691. In addition, for lattice parameters c with a hexagonal crystal structure are 14.1241, 14.1533, 14.3525, and 14.5720. The results of band gap energy values, which is using the Kubelka Munk function for indirect transitions, ranged from 2.6246 – 2.5751 eV.

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.
