Judul: Karakterisasi Optik Film LiTaO3 yang ditumbuhkan di atas Substrat Silikon Tipe-P pada Variasi Suhu Annealing.
Abstrak: Telah berhasil dibuat film tipis LiTaO3 di atas substrat Silikon (100) tipe-p dengan metode Chemical Solution Deposition (CSD) dan spin coating berkecepatan putar 3000 rpm selama 30 detik dalam kelarutan 1 M. Film tipis di annealing pada suhu 550 ⁰C, 575 ⁰C, 600 ⁰C dan 625 ⁰C selama waktu tahan 8 jam dengan laju kenaikan suhu 1.67 ⁰C/menit. Hasil uji optik menunjukkan film LiTaO3 dapat mengabsorpsi cahaya tampak pada near infrared sehingga dapat digunakan sebagai cikal bakal sensor inframerah. Analisis energi gap menggunakan metode Tauc Plot diperoleh hasil nilai 2.649 eV, 2.949 eV, 2.744 eV dan 2.752 eV. Hasil uji sifat listrik memperlihatkan film LiTaO3 bersifat semikonduktor dan konduktif. Analisis XRD film LiTaO3 membentuk struktur kristal hexagonal memiliki parameter a=b=5.153 Å and c=13.89 Å.

Judul: Karakterisasi Optik dan Listrik Film LiTaO3 (Lithium Tantalate) pada Substrat Silikon [Si(111)] Tipe-n/n+
Abstrak: Telah berhasil dibuat film LiTaO3 pada substrat silikon [Si(111)] tipe-n/n+ dengan variasi suhu annealing selama 8 jam pada suhu 550 oC, 575 oC, 600 oC, dan 625 oC. Metode yang digunakan yaitu Chemical Solution Deposition (CSD) dengan spin coating berkecepatan putar 3000 rpm selama 30 detik dalam kelarutan 1 M. Analisis energi band gap menggunakan metode Tauc Plot menghasilkan nilai sebesar 2.59 - 2.72 eV. Hasil analisis XRD untuk film LiTaO3 pada suhu annealing 600 oC menunjukkan bahwa struktur kristalnya membentuk hexagonal dengan parameter kisi a = b = 5.199Å dan c = 13.890Å. Hasil uji optik menunjukkan bahwa film LiTaO3 dapat mengabsorbsi spektrum Inframerah dekat dengan transisi indirect. Hasil uji listrik menunjukkan bahwa film LiTaO3 termasuk material semikonduktor

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.
