Judul: Komposisi Jaringan Pada Potongan Karkas Domba Garut Dan Ekor tipis Umur Enam Bulan Dengan Ransum Berbasis Indigofera sp
Abstrak: Meat from younger lamb is more desirable than that from older lamb. The objective this study was to investigate the effect of breed from local sheep on carcass tissue composition and distribution within wholesale cuts. The experiment used four Garut and four Thin Tail lamb aged three months old. They were fattened for three month with pelleted ration comprising 30% Indigofera sp. and 70% concentrate. The results showed that carcass composition and distribution within wholesale cuts were similar between Garut and Thin Tail lamb. Garut lamb carcass had significantly higher twelveth rib fat thickness than that from Thin Tail lamb carcass. The results of this study indicate that Garut and Thin tail lamb had a meat yield, fat, and bone percentages of 62.48%, 13.62%, and 23.89% respectively. Garut sheep had significantly higher (P <0.05) back fat thicknesethan the thin tail lamb.The meatfrom the “breast” and “shank”cut were significantly higher (P <0.05) in Garut lamb compared Thin Tail lamb.

Abstrak: Lamb is a small ruminant which produces meat for human consumption. The purpose of this study was to examine the influence of ration on carcass characteristics and composition. Eleven male Garut lambs of eight month old were used in the study. They were divided into two groups and given ration containing mung bean waste and Indigofera sp. respectively and fattened for three months. Parameter observed include carcass characteristics, carcass tissue component and distribution within commercial cuts. The result showed the Garut lamb that was given difference ration containing was significantly higher (P<0,05) to slaughter weight, empty body weight, carcass weight, percentage of carcass compared to that fed on ration containing Indigofera sp. Carcass tissue composition include meat and bone weight of Garut lamb fed on mung bean waste ration containing significantly (P<0,05) hevier compared to that fed on Indigofera sp. Meat and bone in carcass tissue distribution within commercial cuts was significantly different, it can be seen from rack, leg, breast, and shank cut

Judul: Bifurkasi Hopf pada Model Siklus Bisnis Kaldor Kalecki tanpa dan dengan Waktu Tunda
Abstrak: Business cycle model is one of dynamical system models in economic. One of the business cycles model is Kaldor-Kalecki model. Kaldor-Kalecki business cycle model that is written in delayed defferential equations, is a business cycle model that involves gross product and capital stock of a company. In this paper Kaldor-Kalecki business cycle model is analyzed using both nondelay and delay in time of capital stock. By Taylor expansion for the time delayed model, an analysis of stability around the fixed points has been done. Furthermore, by using Hopf bifurcation theorem, it can be shown that there exists periodic orbits and limit cycle. In the nondelayed model, changing the parameter of goods market could lead to the occurrence of Hopf bifurcation and the existence of limit cycle. Similarly, for the delayed model, it has been shown that changing the time delay parameter may result in the occurrence of Hopf bifurcation and limit cycle.
