Judul: Persentase karkas, organ dalam dan lemak abdomen ayam broiler yang diberi feed additive sigi indah
Abstrak: This research wvas conducted to determine the effect of supplementation of SlGl INDAH as feed additive in broiler drinking water on the carcass, vital organ and abdominal fat percentage and to get suitable level of the supplementation of SlGI INDAH to improve broiler performance. 1,050 day old chicks of Cobb strain were grouped into 7 treatments and 5 replications. The treahnents were level of supplementation of SIGI INDAH in the diets namely PO (W), PI (0.25%), P2 (0.50%), P3 (0.75%), P4 (1 .W?P)5 (,1.2 5%), P6 (1.50%). l kr esults showed that the supplementation of SIGl INDAH did not significantly affect carcass, viscera and abdominal fat weight of boilers. It is concluded that SlGI INDAH product could not improve carcass and viscera weight of broiler.Key words: Feed additive, Broiler, Carcass, Vital organ, Abdominal fat

Judul: Performa dan nilai ekonomis ayam broiler yang diberi feed additive "Sigi Indah" dalam air minum
Abstrak: This study was conducted to investigate the effect of feed additive "SIGI INDAH" on broiler's performance, economical value and to get suitable level of the addition of "SIGI INDAH". The experiment was conducted in Completely Randomized Design using 840 day old chicks (DOC) Cobb 500 strain. Seven levels of "SIGI INDAH (0%, 0.25%, 0.50%, 0.75%, 1.00%, 1.25% and 1.50%) were added to drinking water of broiler as the treatments. Each treatment had 4 replication with 30 broilers. Growth performance (feed intake, BW gain, FCR and mortality) were obtained through 35 days. Cumulative feed intake at day 35 was improved (P< 0.05) in broilers given 0.50%,,0.75%, 1.00%, 1.25% and 1.50% compared with that of 0%. BW gain, FCR and water consumption were no significant difference among treatment. Mortality was higher for broiler consuming 0.50% compared to the other treatments. The average of IOFCC for broiler received "SIGI INDAH" (Rp 2,458.60) lower than those for 0% (Ru 3,320.95). In conclusion, feed additive "SIGI INDAW did not improve broiler's performance and give profit. Key words : broiler, feed additive, performance, ZOFCC

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.
