One serving size of chicken liver nugget is equivalent to 4 pieces of nuggets and it contributes about 168 kcal of energy/day. The selected formula have met the requirements of nutritional claim for protein source, low fat, and high iron and vitamin A content., Remaja merupakan fase kehidupan yang penting dimana terjadi peningkatan kebutuhan gizi dalam rangka menunjang pertumbuhan dan perkembangan tubuh menuju kedewasaan. Anemia dan Kekurangan Vitamin A (KVA) merupakan dua masalah gizi yang terjadi pada remaja putri yang disebabkan oleh asupan zat gizi (baik makro maupun mikro) yang inadekuat. Naget ayam dengan substitusi hati ayam merupakan salah satu alternatif makanan selingan yang dapat membantu meningkatkan asupan zat besi dan vitamin A pada remaja putri. Penelitian ini bertujuan untuk mengembangan serta menganalisis kandungan gizi produk naget berbahan dasar hati ayam.

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.
