Judul: Analisis Permintaan dan Konsumsi Sumber Protein Hewani Rumah Tangga di Pulau Jawa
Abstrak: Konsumsi atau permintaan produk pangan hewani sangat berkaitan erat dengan kemampuan atau daya beli konsumen, karena harganya yang relatif lebih tinggi dibanding komoditas pangan lainnya. Menurut Soedjana, Rusastra dan Sudaryanto (1998), dapat dikatakan bahwa daging,telur, susu dan ikan merupakan produk-produk pangan hewani yang elastis terhadap pendapatan. Dan saat ini meskipun kuantitas ketersediaan pangan hewani baik yang berasal dari ternak maupun ikan sudah melampaui tingkat kecukupan, ironisnya konsumsi pangannya masih jauh dari tingkat kecukupan.

Judul: Analisis Konsumsi Pangan Sumber Protein Hewani Rumah Tangga Di Propinsi Bali
Abstrak: Permasalahan penelitian ini adalah untuk mempelajari penerapan model yang tepat terhadap sistem permintaan pangan sumber protein hewani rumahtangga di Propinsi Bali. Disamping itu untuk memperoleh informasi mengenai keragaan konsumsi pangan sumber protein hewani dan besaran elastisitas harga, silang dan elastisitas pengeluaran. Serta mengkaji penyebaran pengeluaran sebagai proksi dari pendapatan dengan koefisien Gini. Tujuan penelitian ini adalah memperoleh gambaran tentang sistem permintaan pangan sumber protein hewani rumahtangga di Propinsi Bali dan besaran parameter yang diduga serta koefisien Gini. Analisis akan dibedakan menurut lokasi tempat tinggal (desa/kota). Data yang dipergunakan adalah data SUSENAS (Survei Sosial Ekonomi Nasional) tahun 1993. Survei ini dilakukan oleh Biro Pusat Statistik (BPS) sebagai survei konsumsi/pengeluaran rumahtangga. Pola konsumsi pangan sumber protein hewani sebagian besar penduduk/rumahtangga di Propinsi Bali yang didekati dengan proporsi/share pengeluaran makanan sangat dipengaruhi oleh keragaman daerah/wilayah (desa/kota). Komoditi ikan, menduduki proporsi kedua setelah daging. Komoditi ini lebih digemari di kota dibandingkan di desa, dengan kecenderungan makin tinggi tingkat pendapatan makin tinggi tingkat konsumsi komoditi ini. Komoditi daging, merupakan komoditi yang paling besar nilai konsumsinya, baik di desa maupun di kota, dimana pangsa pengeluaran mencapai kira-kira 16 persen dari total anggaran makanan…dst

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
