Judul: Analisis pendapatan keluarga peternak penggaduh sapi potong pada dua kecamatan yang berbeda di kabupaten Daerah Tingkat II Ngawi, Jawa Timur
Abstrak: Salah satu upaya yang dilakukan Dinas Peternakan Kabupaten Daerah Tingkat II Ngawi dalam pengembangan dan penyebaran ternak pemerintah sekaligus meningkatkan Pendapatan Asli Daerah (PAD) adalah dengan melakukan penyebaran bantuan ternak sapi potong untuk digemukkan dengan cara kereman menggunakan sistem gaduhan. Lokasi - lokasi pengembangan ternak kereman ini diantaranya adalah Kecamatan Ngawi dan Kecamatan Kedunggalar. Penelitian ini dilakukan di Kecamatan Ngawi (Desa Karangtengah Prandon) dan Kecamatan Kedunggalar (Desa Kedunggalar dan Desa Kawu). Tujuan penelitian adalah : 1) untuk mengetahui pelaksanaan sistem gaduhan sapi kereman milik pemerintah, 2) mengetahui manajemen budidaya sapi kereman, 3) mengukur tingkat pendapatan dan keuntungan yang diperoleh keluarga peternak penggaduh dari usahaternak gaduhan yang dijalankan, 4) mengetahui sumbangan pendapatan yang diterima keluarga peternak penggaduh dari usahatemak gaduhan terhadap total pendapatan keluarga.

Judul: Analisis Sistem Bagi Hasil Ternak Sapi Kereman Program Bantuan Pemerintah (Kasus di Kecamatan Tirto dan Kecamatan Paninggaran, Kabupaten Pekalongan).
Abstrak: Usaha petemakan sapi potong di Kecamatan Tirto dan Kecamatan Paninggaran, Kabupaten Pekalongan umumnya adalah petemakan rakyat atau usaha keluarga, yang merupakan usaha sampingan dengan pengelolaan yang masih tradisional. Skala usaha, lahan, dan modal yang dimiliki juga masih relatif kecil. Hal ini mendorong Pemerintah Propinsi Jawa Tengah dan Pemerintah Kabupaten Pekalongan melalui Dinas Pertanian Kabupaten Pekalongan memberikan Program Pinjaman Modal Usaha (PMU) dan Program Pemberdayaan Ekonomi Rakyat (PER) terutama bagi masyarakat yang kesulitan mendapatkan modal melalui sistem bagi basi!. Tujuan dari penelitian ini adalah: 1) mempelajari mekanisme, prosedur dan gambaran dari sistem bagi basil kedua program penggemukan sapi potong, 2) menghitung pendapatan peternak penggaduh yang berperan sebagai agent, 3) menganalisis kontribusi pendapatan yang diterima keluarga peternak penggaduh dan 4) mengevaluasi tingkat pengembalian modal pemerintah yang berperan sebagai principal. Penelitian ini dilakukan dengan metode survei di Kecamatan Tirto dan Kecamatan Paninggaran.

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
