Judul: Rancang Bangun Sistem Pakar Pemilihan Konstruksi Kandang Tertutup untuk Produksi Ayam Broiler.
Abstrak: Broiler is one of important commodity in livestock sector which is highly needed in Indonesia. Broilers growth rapidly and harvested in young age at 28-35 days (short rearing periode). One of the key success factors of broiler production is the provision of comfortable housing environment. The relatively new technology available for good broiler production is a broiler closed house that provides more controlled and comfortable environment boiler production. However, adequate information and knowledge about a broiler closed house is not widely available for public, especially broiler farmers. The aim of this research is to build a web-based expert system for the selection of various constructions of broiler closed house systems. The developed prototype was built using PHP programming language and MySQL database management system. The selection of broiler construction can be accessed and viewed interactively to finally produce printable 2-D and 3-D objects of broiler closed house. The test results by using three different web browsers (Internet Explorer v11.0, v43.0 Google Chrome, and Opera v30.0) showed that the expert system can be accessed correctly and properly for all browsers. The speed web browser for accessing web expert system is influenced by the speed of internet access on a computer device that is used.

Judul: Knowledge base development system of cultivation broiler closed house
Abstrak: Protein requirement of Indonesian people is increasing due to the increase of population. Broiler is popular meat, cheap, and easy to obtain. However, broiler production still does not to fulfill the needs of the people of Indonesia flesh. The main cause of inadequate broiler production is still conventional farming systems. This research aims to design and build a knowledge base broiler farming management using a variety of computer-based application system that provides knowledge in the form of stages - stages of cultivation which include DOC management, the management of food and drink, environmental management, and agriculture-based disease management precision and stored in the system database. DBMS closed cultivation broiler house to be built will be concentrated on the four points which include DOC (Day Old Chick), food, environment, and disease. DOC will be informed at the point related guidance in the selection and management of initial DOC. In the feed point will be informed about the density of the cage, feed system and drinking system. Point environment will provide information related to litter, temperature, ventilation, and lighting. Point of disease is the last point to be discussed, the point will be informed of the name of a possible disease suffered by broiler chickens, the cause of the disease, prevention and treatment.

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.
