Judul: Protein Cacing Tanah Sebagai Sumber Protein Alternatif dari Pengolahan Limbah Ruminansia Besar.
Abstrak: Population growth in Indonesia is very rapidly led to increased demand for animal protein. Hence the need for alternative protein sources to meet the needs of the human protein. Earthworms contain high protein so it can be used as an alternative protein source. Livestock waste which if not handled properly can damage the environment. Therefore, the waste from livestock can be used as feed worms. The purpose of this study was to determine the potential of earthworms as a source of alternative porotein by utilizing the processing of livestock waste as feed worms. This study was done in Raya Dramaga street Km 7, Village Marga Jaya, District Dramaga, Bogor regency. The data used in this research is secondary data which include statistical data of the number of cattle in Indonesian, census, production and consumption of livestock products. Variables measured is the population of worms, the worms feed sufficiency, protein production livestock products, and protein consumption of livestock products. The results showed that the worms can be used as an alternative source of protein and livestock waste can meet the needs of feed worm.

Abstrak: Earthworm was detrivor animal could solve odor problem of organic waste, decreasing the organic waste and it's metabolic worth for fertilizer. The aims of this study were obtained earthworm's body weight gain and mortality in different level of treatment. The study was held from September 20th until 8th December 2005 at Non Ruminants and Prospective Animal Division, Department of Animal Production and Technology, Faculty of Animal Science, Bogor Agricultural University. The experiment used Complete Randomized Design in four feeding level treatments consists of 1; 1.25; 1.5; 1.75 body weight earthworms. Each treatment had five replications which contained 2.3 grams earthworm aged two weeks old, length 3.25 cm. Observed variables were body weight, body weight gain and mortality. Data were analyze using ANOVA and tested using Polynomial Orthogonal to examine the differences among treatments. The results showed that feed levels affected the body weight gain but not the earthworm's mortality. Elevation feed increased body weight gain of earthworm but the treatment could accumulation of oil on bedding. Oil accumulation in bedding appear as uncomforted environtment to earthworms, thus the body weight gain reduce until negative value. Food restaurant waste can be used as earthwarm's meal but the bedding must be in large supply. Keywords: Lurnbricus rubellus, food restaurant waste, body weight gain, mortality

Judul: Kekonsistenan Hamiltonian pada Gerak Gelombang Interfacial
Abstrak: The interfacial wave is an internal wave that occurs at boundary of two layers fluid. It appears because there is difference of mass density between the two layers. The objective of this thesis is to formulate the motion of internal wave with flat base and flat as well as free upper bound surface. The motion equation obtained is a Hamiltonian system. The Hamiltonian in this system is expressed by variable of wave deviation and horizontal component of potential velocity. Under assumption that interfacial wave moves only in one direction, it can be shown that the Hamiltonian depends on the solution of the wave motion equation. The coefficients of the equation depend on the physical characteristics of the two layers of fluid, i.e. thickness and mass density. The numerical results show that Hamiltonian in the system is constant. It is consistent with Hamiltonian characteristic, which does not depend on time.
