Abstrak: Herbs have several benefit to improve the immunity. Animal also can take the benefit of it. This research aimed to study the effects of herbs blended with water to the performance of quail and cholesterol level of quail eggs. The research using 320 female quails then the ages were 36 weeks were maintained in 8 weeks. Feed contained 18 % of protein and energy 3876 kkal kg-1. The treatments consists of R0 (control), R1 (30 ml of herbs l-1 of water), R2 (60 ml of herbs l-1 of water), R3 (90 ml of herbs l-1 of water). The design of research was using completely randomized design (CRD) with 4 treatments and 2 replications then the data was analysed descriptively. The results of this study indicate that herbal contained flavonoids, saponins, and tannins. All herbs increase the level of provision of feed consumption, water consumption and lowering cholesterol eggs. Egg production in this study ranged between 58.62-65.4%, feed convertion ranged between 2.96-3.60, and the weight of eggs were 9.69-10.0 g butir-1. 30 ml of herbs increase 65% egg production decrease feed convertion 2.96 and egg cholesterol 2.73 mg 100 mg-1.

Judul: Performa produksi burung puyuh (Coturnix-coturnix japonica) yang diberi pakan dengan suplementasi omega-3
Abstrak: Supplementation of Omega-3 in ration may enhance Omega-3 and lower the cholesterol contents in quail eggs. However, its impact to productive performances has not been clearly proved. This current experiment aimed to study the influence of Omega-3 supplementation in ration on productive performances of Japanese quail (Coturnix-coturnix japonica). This study was carried out for two months in the field laboratory of Poultry Production and Technology, Faculty of Animal Science, Bogor Agricultural University. This study involved 298 Japanese quail age 10 weeks and designed completely randomized in 5 treatments with 4 replications. The applied treatments were Omega-3 supplementation in the ration: P1 (control), P2 (1.5% Omega-3), P3 (3% Omega-3), P4 (4.5% Omega-3), and P5 (6% Omega-3). The observed traits were feed consumption, egg production, egg weight, feed conversion, mortality, and index of quail egg. All data were collected and descriptively analyzed. This study revealed no influence of Omega-3 supplementation to the production performance and index of quail egg.

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.
