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: Pengembangan User Interface Manajemen Produksi Broiler dengan Kandang Tertutup
Abstrak: Pertumbuhan permintaan daging ayam broiler pada tahun 2013 melampaui pertumbuhan jumlah penduduk Indonesia. Kenaikan jumlah penduduk 1.6% per tahun sedangkan peningkatan konsumsi daging ayam broiler sekitar 15.8% per tahun. Oleh karena itu, perlu diseminasi tentang manajemen produksi ayam broiler berbasis kandang tertutup pada website sehingga dapat meluas dan diakses dengan mudah oleh masyarakat yang tertarik dalam produksi broiler. Tujuan dari penelitian ini adalah mengembangkan user interface berbasis website untuk manajemen produksi broiler dengan kandang tertutup. Telah dibangun dan diimplementasikan antar muka pengguna menggunakan PHP, HTML, CSS, Jquery, dan MySQL. Website user interface yang diusulkan dirancang berdasarkan aturan dan prinsip-prinsip dari disain website yang fokus pada navigasi yang mudah, tipografi yang relevan dan penggunaan bahasa yang konsisten yang berkaitan dengan aspek-aspek penting dari produksi broiler. Fitur fungsional yang telah dikembangkan dalam sistem yang diajukan meliputi konsultasi, pencarian dan fungsi analisis usaha yang terkait dengan manajemen produksi broiler. Berdasarkan uji kompatibilitas pada antarmuka pengguna yang diusulkan untuk beberapa platform browser website, menunjukkan bahwa user interface secara konsisten berjalan dengan baik di semua browser target., The growth of broiler meat demand in 2013 was beyond the growth in the population of Indonesia. The increase in population was only 1.6% per year while the increase in the consumption of chicken broiler about 15.8% per year. Therefore, there is a need for dissemination of broiler production management in a closed-house system on a website that can be widely and easily accessible by people interested in broiler production. The aim of this research is to develop a website-based user interface for broiler production management in a closed house system. This user interface has been built and implemented using based on PHP, HTML, CSS, Jquery, and MySQL. The proposed website user interface has been designed based on the rules and principles of website design focusing on easy navigation, relevant typography and consistent language related to the vital aspects of broiler production. The functional features that have been developed in the proposed system include consultation, searching, and business analysis functions related to broiler production management. Based on the compatibility test on the proposed user interface to several website browser platforms, it was shown that the user interface consistently run well on all target browsers.

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.
