Judul: Quail Blood Glucose Levels in Starter, Grower and Layer Phases
Abstrak: Puyuh merupakan salah satu unggas yang dapat menghasilkan telur dan daging yang berperan sebagai sumber protein hewani di Indonesia. Puyuh memiliki tiga fase pemeliharaan yang kemungkinan membutuhkan jumlah karbohidrat yang berbeda yang dibutuhkan dalam proses pertumbuhan. Glukosa merupakan salah satu senyawa karbohidrat yang berperan sebagai sumber energi utama dalam proses metabolisme. Penelitian ini bertujuan mengetahui kadar glukosa darah burung puyuh (Coturnix coturnix Japonica) pada fase starter, grower, dan layer. Penelitian ini menggunakan puyuh sebanya 30 ekor puyuh yang terdiri dari 10 ekor puyuh pada fase starter (umur 18 hari), 10 ekor pada fase grower (umur 25 hari), dan 10 ekor pada fase layer (umur 330 hari). Pengukuran kadar glukosa darah menggunakan glukometer (EasyTouch® GCU) dengan pengambilan darah melalui vena brachialis. Rata-rata hasil pengukuran masing-masing pada fase starter, grower, dan layer yaitu 282,30; 266,40; dan 257,60 mg/dL dengan rata-rata bobot badan secara berurutan 70; 103.50; dan 213,20. Analisis statistik menunjukkan hasil bahwa tidak ada pengaruh fase pemeliharaan dengan kadar glukosa darah puyuh. Hasil penelitian ini diharapkan dapat berguna bagi peternak maupun praktisi dalam mengetahui kondisi fisiologi puyuh (kadar glukosa darah) pada setiap fase pertumbuhan puyuh., Quail is one of the poultry that produces eggs and meat. This Product is a source of animal protein in Indonesia. Quail has three phases of rearing which may require different amounts of carbohydrates needed in the growth process. Glucose is a carbohydrate compound that acts as the main energy source in metabolic processes. This study aims to determine the blood glucose levels of quail (Coturnix coturnix Japonica) in the starter, grower and layer phases. This study used 30 female quails consisting of 10 quail in each phase with age of starter phase, grower phase and the layer phase 18, 25 and 330 days respectively. Measurement of blood glucose levels using a glucometer (EasyTouch® GCU) by taking blood through the brachial vein. The average results of each measurement in the starter, grower, and layer phases are 282.30; 266.40; and 257.60 mg/dL with an average body weight of 70;103.50; and 213.20. Statistical analysis showed that there was no effect of the rearing phase on quail blood glucose levels. The results of this study are expected to be useful for both farmers and veterinary clinicians in understanding the physiological condition of quail (blood glucose level) in each phase of quail growth.

Judul: Quail Blood Cholesterol Levels (Coturnix coturnix Japonica) On Starters, Growers and Layers phase
Abstrak: Cholesterol is one of fat formation components which is also the main sterol in animal tissues. Therefore its presence are contributing to development and growth of the body. This study aimed to determine blood cholesterol levels and body weight of quail in the starter,grower and layer phases, which were taken at the age of 18 days, 25 days and 330 days. The quail (Coturnix coturnix Japonica) used were ten tails of the starter phase, grower phase and layer phase. Blood cholesterol levels were measured using a NESCO MultiCheck 3 in 1 tool and body weight was calculated using a digital scale. Cholesterol levels decreased from the starter (158,40 mg/dL) phase to the grower phase (123,00 mg/dL) and increased again in the layer phase (219,6 mg/dL). The highest blood cholesterol value was obtained in the layer phase. The body weight over time continued to experience an increase and the increase in body weight from the starter to the layer phase was not followed by an increase in cholesterol levels. Cholesterol levels are used according to their physiological needs, Kolesterol merupakan salah satu komponen pembentuk lemak yang juga merupakan sterol utama dalam jaringan hewan, oleh karena itu kehadirannya memberikan kontribusi untuk perkembangan dan pertumbuhan tubuh. Penelitian ini bertujuan untuk mengetahui kadar kolesterol darah dan bobot badan burung puyuh pada fase starter, grower dan layer, yang diambil pada umur 18 hari, 25 hari dan 330 hari. Burung puyuh (Coturnix coturnix Japonica) yang digunakan sebanyak sepuluh ekor pada masing-masing fase starter, fase grower dan fase layer. Kadar kolesterol darah diukur menggunakan alat NESCO MultiCheck 3 in 1 dan berat badan dihitung menggunakan timbangan digital. Kadar kolesterol menurun dari fase starter (158,40 mg/dL) ke fase grower(123,00 mg/dL) dan meningkat lagi pada fase layer(219,6 mg/dL). Nilai kolesterol darah tertinggi diperoleh pada fase layer. Bobot badan dari waktu ke waktu terus mengalami peningkatan yang dan peningkatan bobot badan dari fase starter ke fase layer tidak diikuti dengan peningkatan kadar kolesterol yang artinya bobot badan tidak berpengaruh pada kadar kolesterol burung puyuh. Kadar kolesterol digunakan sesuai dengan kebutuhan fisiologisnya

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.
