Judul: Sistem pakar diagnosa penyakit ayam (SPDPPA)
Abstrak: Sistem Pakar Diagnosa Penyakit Pada Ayam (SPDPPA ) merupakan suatu sistem komputer yang dikembangkan untuk mendiagnosa penyakit pada ayam berdasar gejala-gejala klinis dan perubahan makroskopis yang terdapat pada ayam yang diidentifikasi terinfeksi penyakit. Salah satu metode inferensia yang digunakan pada penelitian ini adalah fuzzy inference system (FIS). Dengan fuzzy inference system ini gejala-gejala yang memiliki kemiripan pada saat pendiagnosaan dapat diatasi. Penyakit yang terdiagnosa pada SPD PPA dibatasi hanya pada tiga penyakit, yaitu: Avian Influenza (AI), Newcastle Disease (ND) dan Infectious Laryngotracheitis (ILT). Pada penelitian ini rancang bangun SPDPPA mengalami dua jenis alur pendiagnosaan. Pada pendiagnosaan pertama, data fuzzy berupa warna pial yang dibagi menjadi 10 kelompok warna, umur ayam, angka kematian dan suhu tubuh akan dijadikan sebagai masukan. Data tersebut akan proses oleh fuzzy inference sys tem. Keluaran proses akan berupa diagnosa sementara dengan kriteria mendukung ILT, sangat mendukung ILT, mendukung ND, sangat mendukung ND, mendukung AI dan sangat mendukung AI. Pengujian sistem untuk data fuzzy dilakukan dengan mengkombinasikan beberapa masukan.

Judul: Sistem deteksi dini dan pencegahan penyakit pada ternak unggas secara online
Abstrak: Disease control on poultry farming can be one determining factor to get the economy success. A sick poultry will make the weight gain decreased, and result in economic losses. Poultry disease can be detected faster by the symptom shown by poultry itself. This Online Poultry Early Detection and Illness Prevention Information System (OPEDIPIS) could help farmer to detect the illness before its outbreak. This system diagnoses the desease by enter the symptome of the desease to computer system, and then the system compute the possible illness of the poultry based on the symptom that had been input to the system data base. The OPEDIPIS was developed using System Development Life Cycle Method (SDLC). SDLC consisted of 5 systems, they were investigation, analyze, design, implementation, and maintaining systems. The system is good for some disease that have symptoms in the vital body but it cant be used to cure the illness, this system can only recommend some prevention method to help stop spreading the disease.

Judul: Enhancement of photon absorbtion on BaxSr1-xTiO3 thin films semiconductor using photonic crystals.
Abstrak: In this research, has been conducted BaxSr1-xTiO3 (BST) thin films manufacturing for mole fraction x = 0.25, 0.35, 0.45, and 0.55; and concentration of 1 molar using chemical solution depositon (CSD) method. The materials, which are used in this research, are barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%], titanium isopropoxide [Ti(C12O4H28), 97.999%], gallium trioxide [Ga2O3], 2-methoxyethanol [H3COOCH2CH2OH, 99%] and 1 x 1 cm of transparent conductive oxide (TCO) glass as substrate. Two BST thin films are made that for BST thin films which are doped by 10% galium (BGST) as p-type layer and pure BST solution as n-type. BST solution is made by reacting barium acetate [Ba(CH3COO)2, 99%], strontium acetate [Sr(CH3COO)2, 99%] and titanium isopropoxide [Ti(C12O4H28)] into 2-methoxyethanol solvent [H3COOCH2CH2OH, 99%] in accordance with mass gram for each x value. While, BGST solution is made in the same way as BST solution, plus adding gallium at 10% of the mass of BST. Once all materials are reacted, then vibrated using ultrasonic for 90 minutes, and followed by coating BGST / BST on the TCO substrate. Once the layer is formed, then annealed for 15 hours at temperature of 500 °C with increasing rate of 1.67 oC/minute. Characterizations of BST thin films with or without photonic crystals include the absorbance and transmittance in the visible light spectrum, as well as the electrical photoconductivity characterizations. From BST thin films without photonic crystals indicate that our thin films have light absorption area on almost the entire range of the visible light spectrum even to the infrared range with absorption value over than 67.6%, in addition, it can be seen that the maximum absorbance of BST thin films for all mole fractions lie in blue to green light spectrum region, 457 nm ≤ λ ≤ 570 nm and the minimum in yellow to red light spectrum region, 570 nm ≤ λ ≤ 678 nm. The largest absorbance is found at x = 0.25 with average absorbance value of 92.04% and maximum and minimum absorbance peaks at wavelength of 500.89 and 657.72 nm, respectively. At x = 0.35, average absorbance value decreased to 83.55% with maximum and minimum peaks at 505.73 and 613.68 nm, respectively. Then increased to 91.16% at x = 0.45 with maximum and minimum peaks at 506.04 and 618.56 nm, respectively. At x = 0.55, average absorbance value decreased to 80.12% with maximum and minimum peaks at 507.85 and 608.79 nm, respectively. Moreover, it can be seen that the addition of barium mole fraction leads to wider maximum absorbance or minimum transmittance peaks and narrower minimum absorbance or maximum transmittance peaks in the same range of the green and blue & red light spectrums, respectively. BST thin films with photonic crystals show increasing in absorption for all x values in the range of 3.04 into 13.33%. At x = 0.25, average absorbance percentage increased 3.96% from 92.4 into 95.68%, for x = 0.35 average percentage increased 7.07% into 89.45 from 83.55%. Furthermore, average absorbance of BST thin films at x = 0.45 increased 3.04% from 91.16 into 93.93% and x = 0.55 has
