Judul: Synthesis and Characterization FeTiO3 dopped Strontium (II) Acetate (Sr(CH3COO)2)
Abstrak: Film FeTiO3 dengan variasi konsentrasi pendadah Stronsium (II) Asetat (0%, 0.5%, 1%, 1,5%) telah berhasil dibuat di atas substrat silikon (100) tipe-p menggunakan metode Chemical Solution Deposition (CSD) dengan bantuan teknik spin coating dengan kecepatan putar 8000 rpm. Film FeTiO3 di-annealing dengan kelajuan suhu sebesar 1,67oC dan pada suhu 850 oC ditahan selama 8 jam, lalu mengikuti proses pendinginan suhu kamar selama 12 jam. Film FeTiO3 yang didadah dengan Stronsium (II) Asetat dikarakterisasi menggunakan spektrofotometer UV-Vis dan XRD sehingga menghasilkan nilai energi bandgap secara berturut-turut sebesar 4,14 eV; 3,98 eV; 3,13 eV; 3,08 eV. Analisis data XRD menggunakan metode Cramer-Cohen menghasilkan nilai parameter kisi a=b sebesar 5,0934 Å; 5,1379 Å; 5,1657 Å; dan 5,1779 Å serta parameter kisi c yaitu 14,0787 Å; 14,3008 Å; 14,4038 Å; dan 14,4289 Å, dengan struktur kristal hexagonal. Kata kunci: bandgap, CSD, FeTiO3, spin coating, parameter kisi, FeTiO3 film with the variation of Strontium (II) Acetate (0%; 0,5%;1%;1,5%) has been successfully made on silicon substrate (100) p-type using the Chemical Solution Deposition (CSD) method with the spin coating technique with a rotational speed 8000 rpm. FeTiO3 film was annealed with an increase in temperature of 1,67oC and at 850oC for 8 hours, then follow the cooling process to room temperature for 12 hours. FeTiO3 film with Strontium (II) Acetate doped was characterization using a spectrophotometer UV-Vis and XRD so that the bandgap energy value was 4,14 eV; 3,98 eV; 3,13 eV; 3,08 eV. XRD data analysis using the Cramer-Cohen method resulted in lattice parameter values a=b of 5,0934 Å; 5,1379 Å; 5,1657 Å; and 5,1779 Å in addition for lattice parameter c with a hexagonal crystal structure are 14,0787 Å; 14,3008 Å; 14,4038; and 14,4289 Å.

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.
