Judul: Evaluasi Penerapan Good Farming Practice pada Peternakan Rakyat dan Perusahaan Peternakan di Lampung Tengah
Abstrak: Sapi potong merupakan ternak penghasil daging yang berperan penting dalam pemenuhan kebutuhan protein hewani. Kabupaten Lampung Tengah memiliki potensi pengembangan sapi potong. Potensi tersebut semakin meningkat saat peternak rakyat dan perusahaan peternakan sapi potong melaksanakan budidaya yang baik sehingga diperlukan pedoman beternak yang baik. Penelitian ini bertujuan mengevaluasi penerapan Good Farming Practice (GFP) pada peternakan rakyat dan perusahaan peternakan di Lampung Tengah serta dampaknya terhadap produktivitas sapi potong. Metode penelitian ini menggunakan analisis deskriptif. Peubah yang diamati meliputi pembibitan dan reproduksi, pakan, pengelolaan, kandang dan peralatan, serta kesejahteraan ternak. Hasil evaluasi penerapan GFP menunjukkan nilai rataan 2,74 (cukup baik) untuk peternakan rakyat dan 3,90 (baik) untuk perusahaan peternakan. Perlu adanya peningkatan pada beberapa aspek agar nilai GFP meningkat., Cattle are important livestock for providing meat and fulfilling the need for animal protein. Central lampung district has potential for beef cattle development. Such potential is improved when native farmer and cattle farm company perform good farming practice so that good raising guidelines are needed. The study aims to evaluate the application of Good Farming Practice (GFP) on native farmer and cattle farm company and its effect on the productivity of the cattle. This method of research uses descriptive analysis. Observed hatchlings include breeding and reproduction, food, management, housing and equipment, and the animal welfare. The results of the evaluation of the implementation of GFP showed an average value of 2.74 (good enough) for the native farmer and 3.90 (good) for the cattle farm company. Improvements are needed in several aspects so the value of GFP could increase.

Judul: Evaluasi Penerapan Good Farming Practice pada Peternakan  Rakyat Sapi Potong di Situ Bolang Indramayu
Abstrak: Produktivitas ternak sapi potong domestik belum cukup untuk memenuhi kebutuhan dalam negeri. Sebanyak 90% peternakan sapi di Indonesia dikelola secara tradisional. Penelitian bertujuan mengevaluasi pengelolaan peternakan sapi potong di Peternakan Situ Bolang sesuai Peraturan Menteri Pertanian Republik Indonesia Nomor 46/Permentan/PK.210/8/2015 tentang Good Farming Practice untuk Sapi Potong. Penelitian menggunakan analisis deskriptif kualitatif wawancara kepada 33 responden menggunakan kuesioner dan pengamatan secara langsung. Hasil penelitian dapat dilihat dari nilai aspek Good Farming Practice yaitu pembibitan dan reproduksi, manajemen pakan, tata laksana pemeliharaan, perkandangan, dan kesejahteraan ternak. Penerapan GFP oleh peternak rakyat di Situbolang Indramayu mendapatkan nilai 2,05 tergolong dalam kategori sangat kurang., Domestic beef cattle productivity is not sufficient to meet domestic demand. As many as 90% of cattle farms in Indonesia are managed traditionally. The study aimed to evaluate the management of beef cattle farming in Situ Bolang Farm according to the Regulation of the Minister of Agriculture of the Republic of Indonesia Number 46/Permentan/PK.210/8/2015 about Good Farming Practice for Beef Cattle.

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.
