Judul: The Effect of Taro (Colocasis esculenta (L.) Schott) Leaf Meal in the Diets on Broiler Chicken Performances.
Abstrak: This research was conducted to determine the effect of taro leaf meal on the broiler chicken peeformance as termed of feed consumption, body weight gain, feed convention, final body weight and mortality. Research was carried out at Poultry Nutrition Laboratory, Faculty of Animal Science, Bogor Aglicultural University, from April to Juni 2002 and the chemical analyzes was carried out at Biochemistry and Enzymatic Laboratory, Balitbio, Bogor. One hundred and twenty of days old chick of Hubbard strain broiler were divided into four treatment and three replication (ten chickens for each replication). The diet consisted of four treatment: RO (0 % taro leat), R5 (5 % taro leat), RIO (10% taro leat) and R 15 (15 % taro leaf).

Judul: Evaluasi penambahan tepung daun beluntas (Pluchea indica L.) dalam ransum terhadap tampilan produksi ayam broiler pada kepadatan kandang yang tinggi
Abstrak: This research was conducted to study the effcct of beluntas leaf powder usage in the diet on performances (feed consumption. body weight gain, :eed conversion, water consumption) and cholesterol of the broilers. The research used 162 DOC (day old chicken) strain CP 707. The treatment diets were : R1 (commercial feed without beluntas leaf powder or vitastress). R2 (RI + virastress), R3 (commercial feed + 2% beluntas leaf powder). R4 (commercial feed + 4% beluntas leaf powder),'RS (commercial feed + 6% beluntas leaf powder) and R6 (commercial feed + 8% beluntas leaf powder). The data were analyzed using Analyses of Variance and any significant different were further tested usins Least Significant Difference. The results showed that the treatment diets significantly increased (P<0.01) final body weigh1 and body weight gain and significantly increased (PcO.05) feed consumption and water consumption . However, the treatment diet significantly decreased (P<0.01) feed covenion. Usage of 2?'o beluntas leaf powder gave the best performances i.e., 1,152 g/bird (final body weigh), 1,114g/bird (body weigh gain). 1,69 1 ghird (feed consumption), 1.44 (feed conversion) and A.617mlhird (water consumption). Usage of beluntas leaf powder decreased the cholesterol content of broiler's meat.

Judul: Aproksimasi Fungsi Sinus dan Kosinus sebagai Kombinasi Linear dari Fungsi Eksponensial
Abstrak: Salah satu gagasan yang menarik dalam matematika adalah aproksimasi suatu fungsi oleh fungsi lain. Sebagai contoh, fungsi polinom dapat diaproksimasi menggunakan deret Taylor atau fungsi persamaan diferensial dapat diaproksimasi menggunakan deret Fourier. Adapun fungsi yang dapat mengaproksimasi fungsi lain salah satunya adalah fungsi eksponensial. Kemungkinan mengaproksimasi fungsi dengan kombinasi linear dari fungsi eksponensial dari bentuk eˣ, e²ˣ, ... dianggap sebagai perkembangan sejajar dengan gagasan Deret Taylor yang mengaproksimasi fungsi dengan kombinasi linear dari segi fungsi kuadrat. Fungsi sin x dan cos x digunakan sebagai target untuk menilai seberapa baik aproksimasi yang dilakukan oleh fungsi yang diberikan. Aproksimasi fungsi sinus dan kosinus menggunakan hampiran Taylor lebih akurat dibandingkan dengan aproksimasi menggunakan fungsi eksponensial.
