Judul: Sistem Pakar Diagnosa Kolik Pada Kuda Menggunakan Logika Fuzzy
Abstrak: Colic is a term used to describe various kinds of abdominal discomfort, caused by a variety of reasons ranging from gut hooked up to the entrolit due to worm infestation. Signs of colic vary according to the severity of certain conditions. Very few horses show all the signs at one time. This research propose an expert system for colic diagnosis of horse using fuzzy logic. Colic is identified by heart rate, gut sound, gastric reflux and old incident of colic. This research designed an expert system to determine what type of colic and focus on three types of colic : impaction, tympani and twisted gut. This system is built using Fuzzy Inference System (FIS) with four fuzzy parameters : heart rate, gut sound, gastric reflux and old incident of colic. Rules as knowledge base had been built with 36 rules for each colic. Mamdani method is used as inference process. System gives the type of colic as output. The type of colic also divides into six categories : support tympani, very supportive tympani, support twisted gut, very supportive twisted gut, support impaction, very supportive impaction. Based on verification, system can produce levels of accuracy around 89,89 %, the experimental result shows that fuzzy logic can be used to detect colic. To be used in real condition, this system still develope further, for example by adding other factors as parameters, such as anamnesa or examination of vital signs in horses.

Judul: Hubungan antara kejadian kolik dan faktor-faktor resiko kolik pada kuda   : Kajian kasus pada stable di Bogor dan Tanggerang
Abstrak: Kajian ini bertujuan untuk mengetahui hubungan antara faktor-faktor resiko kolik dan kejadian kolik pada stable di Bogor dan Tangerang. Total populasi yang di ambil adalah 201 ekor kuda. Metode pencarian data dilakukan dengan cara pengamatan langsung, wawancara dan catatan medis dari setiap stable. Pengamatan terhadap hubungan antara faktor-faktor resiko kolik dan incidence rate kolik pada kuda ini disajikan secara deskriptif. Hasil kajian menunjukkan bahwa kejadian kolik pada kuda di Arthayasa Stable, Dwima Turangga Equestrian Club dan Pamulang Stable ada hubungannya dengan frekuensi pemberian konsentrat, keteraturan aktifitas sehari-hari, frekuensi pengikiran gigi, sejarah kejadian kolik, jenis kelamin dan umur. Sedangkan lamanya waktu pengumbaran dan selang waktu pemberian anthelmintika tidak berhubungan dengan kasus kejadian kolik pada kuda.

Judul: Pembuatan Sel Surya Berbasis Film Ferroelektrik Barium Strontium Titanate (Ba0,5Sr0,5TiO3)
Abstrak: Growth of films Ba0,5Sr0,5TiO3 (BST) 1 M has been done with variation of annealing in hold time 8 hours, 15 hours, 22 hours, and 29 hours at constant temperature 8500C, above Si (100) substrate p-type, by using the sol-gel process method which followed with spin coating process at 3000 rpm for 30 seconds. Optics spectroscopy shows that BST film solar cells with annealing hold time 8 hours, 15 hours, and 22 hours, works effectively in wavelength ≥ 700 nm absorption range. Yet for sample with annealing hold time about 29 hours effectively absorb in ≤ 700 nm wavelength range. It obtained BST film refractive index at range 2.0 to 7.0 to wavelength range ±370-870 nm. Band gap BST film value based on annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours respectively 2.60 eV; 3.12 eV: 3.24 eV, and 2.66 eV. Electrical conductivity value which obtained, indicate that the BST film is classified as semiconductor material with conductivity order 10-5-10-4 S / cm. The result of I-V photovoltaic characterization shows the BST film potentially to be a solar cells device with efficiency according to the annealing hold time 8 hours, 15 hours, 22 hours, and 29 hours in a row are 2.68x10-5%, 3.51x10-5%, 4.53x10-5% and 3.22x10-5%
