Judul: Performance Quail (Coturnix coturnix  japonica) Given Drinking Water Containing Sambiloto (Andrographis paniculata)  and Ginger (Zingiber officinale)
Abstrak: Puyuh (Coturnix coturnix japonica) memiliki kelemahan yaitu rentan akan stres yang dapat mengakibatkan penurunan bobot badan dan gangguan pada fungsi reproduksi. Salah satu bahan yang ditambahkan untuk meningkatkan kekebalan tubuh dan produktivitas puyuh adalah sambiloto (Andrographis paniculata) dan jahe (Zingiber officinale). Penelitian ini bertujuan menganalisis performa puyuh yang diberi air minum mengandung ekstrak sambilato dan jahe. Penelitian ini menggunakan puyuh petelur usia 3-5 minggu yang diberi air minum mengandung sambiloto dan jahe dengan konsentrasi 0%, 3%, 6% dan 9%. Variabel yang diamati adalah produksi telur, bobot telur, konsumsi pakan, konversi pakan, konsumsi air minum, bobot hidup puyuh, bobot darah, bobot bulu, bobot jeroan, IOFC (Income Over Feed Cost), dan mortalitas. Puyuh yang diberi jahe dan sambiloto pada air minum tidak menunjukan hasil yang berbeda nyata pada performa puyuh. Hasil penelitian menunjukan bahwa puyuh yang diberi air minum mengandung sambiloto dan jahe berpengaruh nyata (P<0,05) terhadap produksi telur. Penambahan 6% mencapai angka tertinggi pada variabel produksi telur yaitu 46%., Quail (Coturnix coturnix japonica) have disadvantage of being susceptible to stress, which can lead to weight loss and disruption of reproductive function. One of the ingredients added to improve quail immunity and productivity is ginger and sambiloto. This study aimed to analyze the performance of quails fed drinking water containing sambilato (Andrographis paniculata) and ginger (Zingiber officinale) extracts. This study used laying quails aged 3-5 weeks that were given drinking water containing sambiloto and ginger with concentrations of 0%, 3%, 6% and 9%. The observed variables were egg production, egg weight, feed consumption, feed conversion, drinking water consumption, quail live weight before slaughter, blood weight, feather weight, offal weight, IOFC (Income Over Feed Cost), and mortality. Quail given ginger and sambiloto in drinking water did not show significantly different results on quail performance. The results showed that quails fed drinking water containing sambiloto and ginger had a significant effect (P<0.05) on egg production. The addition of 6% reached the highest number on the egg production variable which was 46%.

Judul: Pengaruh Pemberian Jamu Terhadap Performa dan Kandungan Kolesterol Telur Burung Puyuh
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: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
