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.

Abstrak: Tapioca starch is very potential to be used as biodegradable plastic materials. However, its hydrophilic nature makes the plastic produced fragile and needs addition of plastic. In this research, bioplastics of tapioca starchcarrageenan blend in 7:3 and 8:2 ratio, was added with carrageenan in 1, 2, and 3% concentrations. Analysis of specific gravity, functional group, mechanical and thermal analysis, as well as morphology were carried out to the plastic product. The highest tensile strength and elongation were obtained at 8:2 ratio with addition of 2% carrageenan, which are 275.55 MPa and 33.18%, respectively. Infrared spectrum showed no new functional group formation. Thermal analysis with differential scanning calorimetry at 1 and 2% carageenan concentrations showed melting point at 102.36 and 115.60 ℃, respectively. Scanning electron microscopy analysis showed a homogeneous morphology. Based on the results, the plastic obtained can be developed as edible film

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.
