Judul: Pengaruh Penambahan TiO2 pada Ciri Zeolit yang Disintesis dari Kaolin Alam.
Abstrak: Penelitian terdahulu menunjukkan bahwa sintesis nanokomposit zeolit/TiO2 secara hidrotermal dengan penambahan TiO2 sebelum kristal zeolit terbentuk, menghasilkan jenis zeolit sintetik yang berbeda-beda. Penelitian ini bertujuan mengamati pengaruh penambahan TiO2 pada ciri zeolit. Bahan dasar sintesis zeolit adalah kaolin alam dari Bangka Belitung. Nanokomposit zeolit/TiO2 disiapkan dengan nisbah metakaolin:TiO2 95:5%, 90:10%, 85:15%, dan 80:20% b/b pada suhu 100 ºC selama 24 jam dengan ragam konsentrasi NaOH 1.5, 2, dan 2.5N. Zeolit dan nanokomposit zeolit/TiO2 yang diperoleh dicirikan menggunakan difraksi sinar-X, spektrometer inframerah transformasi Fourier, dan mikroskop elektron payaran. Sintesis zeolit tanpa tambahan TiO2 menghasilkan zeolit A, sementara tambahan TiO2 menghasilkan zeolit tipe sodalit. Diamati juga bahwa NaOH memengaruhi derajat kristalinitas, dengan konsentrasi NaOH terbaik dalam sintesis zeolit dan nanokomposit zeolit/TiO2 sebesar 2N.

Judul: Sintesis Zeolit X Dan Nanokomposit Zeolit/TiO2 Dari Kaolin Dengan Sekam Padi Sebagai Sumber Silika
Abstrak: Zeolite X was synthesized from kaolin originated from Bangka Belitung and was added with silica from rice husk ash. Zeolite X was synthesized because it has many benefits, including as an adsorbent. Kaolin was used as raw material due to its high content of silica and alumina, which were 48.03% and 35.50% respectively. Meanwhile, silica from rice husk ash was used in the form of sodium silicate. Zeolite was synthesized through hydrothermal process inside a polypropylene bottles, by mixing metakaolin, the calcined form of kaolin heated at 700 °C for 6 hours, with sodium silicate and NaOH to activate the major components of Si and Al in the kaolin. Hydrothermal processes were carried out at 100 °C for 24 hours with NaOH concentrations of 1.5 N and 2.5 N. The concentration of NaOH used was resulted in certain type of zeolite obtained. Zeolite X was obtained when the addition 2.5 N NaOH with NaP1 and Faujasite as impurities. On the other hand, NaOH 1.5 N gave NaP1 zeolite. Modification of zeolite to nanocomposite zeolit/TiO2 was shown to have better capability, that was adsorption-photocatalytic property due to its ability to degrade methylene blue under ultraviolet light.

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.
