Judul: Pembuatan dan Pencirian Bioplastik dari Komposit Pati Tapioka- Agar Kertas Terplastisasi Sorbitol dan Limonena
Abstrak: Bioplastic made of tapioca starch plasticized using sorbitol and limonene is potential as environmentally friendly packaging. The bioplastic composite was prepared in 9 composition of bioplastic. Bioplastic was made by using 2 heating temperature at 40 °C dan 70-79 °C. Some of characteristic of bioplastic was analyzed for their, specific gravity, tensile strength, elongation, thermal properties, morphological, and water vapor permeability. Bioplastic composition with the ratio of agar:sorbitol:limonene (7.5:10:2.5) showed the highest values of density, tensile strength, and elongation properties. However, this composition has low resistance to water vapor. The results of thermal analysis showed decrease of the melting point due to the addition of sorbitol. Thermal analysis showed that there is only a single peak of the sample at the peak of the melting point. The results is in line with scanning electron microscope (SEM) analysis that showed a good homogeneity of the prepared samples.

Judul: Bioplastic composite of tapioca starch plastisized with sorbitol, sodium alginate and limonene
Abstrak: Bioplastik dapat dibuat dari bahan dasar pati dan protein. Bioplastik berbahan dasar pati memiliki keuntungan, yaitu harga yang relatif murah dan mudah didapat dibandingkan protein. Akan tetapi, bioplastik berbahan dasar pati lebih rapuh, sehingga diperlukan bahan tambahan untuk mengatasi kerapuhan. Tujuan penelitian ini adalah membuat dan mencirikan bioplastik komposit dari pati tapioka terplastisasi sorbitol, natrium alginat, dan limonena berdasarkan perbedaan komposisinya. Bioplastik dengan tambahan limonena 2.5% memiliki nilai elongasi, kuat tarik, dan bobot jenis yang lebih tinggi dibandingkan bioplastik dengan tambahan limonena 5.0%, 7.5%, dan 10.0%. Penambahan limonena juga menurunkan nilai permeabilitas uap air. Bioplastik dengan komposisi natrium alginat:limonena:sorbitol (10.0:2.5:7.5) lebih stabil terhadap panas yang ditunjukkan dengan suhu leleh lebih tinggi dibandingkan bioplastik dengan komposisi (7.5:2.5:10.0). Pada analisis morfologi, komponen penyusun bioplastik dengan komposisi (7.5:2.5:10.0) terdistribusi merata pada matriks bioplastik yang didukung dengan terdapatnya puncak suhu leleh tunggal pada termogram., Bioplastic can be made of different sources such as starches and proteins. The benefits of bioplastic starch-based are relatively low cost and easily obtained. The disadvantage of starch-based bioplastic is brittle. In this experiment, sodium alginate, limonene and sorbitol were added to overcome that problem. The objectives of this study are to synthesis and characterize the bioplastic made of tapioca starch plastisized with sorbitol, sodium alginate and limonene based on the various compositions. The addition of limonene 2.5% result in highest elongation, tensile strength, and density as compared to compositions (5.0%, 7.5%, and 10.0%). The addition limonene also decreased water vapour permeability. Bioplastic composition of sodium alginate:limonene:sorbitol (10.0:2.5:7.5) has more heat stability than that of the composition of (7.5:2.5:10.0) which showing a higher melting point. Morphology analysis showed that the bioplastic composition of (7.5:2.5:10.0) distributed evenly on the matrix of bioplastics as supported by a single melting point peak on the thermogram.

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.
