Judul: Analisis pemasaran daging sapi dan daging ayam dari RPH Cakung dan RPA Pulogadung di DKI Jakarta
Abstrak: Peningkatan kesadaran masyarakat tentang gizi, terutama yang berasal dari komoditas ternak telah menyebabkan meningkatnya konsumsi daging nasional. Salah satu daerah yang paling banyak mengkonsumsi daging tersebut adalah Propinsi DKI Jakarta. Hal ini dikarenakan DKI Jakarta adalah ibukota negara Indonesia dan memiliki jumlah penduduk lebih dari sepuluh juta jiwa. Daging sapi dan daging ayam yang dikonsumsi oleh masyarakat Jakarta tersebut sebagian dipasok dari RPH (Rumah Potong Hewan) dan RPA (Rumah Potong Ayam) yang berada di bawah naungan PD. Dharma Jaya. DKI Jakarta sebagai salah satu daerah yang memiliki penduduk paling banyak di Indonesia, ternyata beberapa tahun terakhir ini (2000-2003) terus mengalami penurunan terhadap permintaan daging sapi dan ayam di DKI Jakarta. Hal ini tercermin dari penurunan jumlah pemotongan ternak sapi dan ayam di RPH Cakung dan RPA Pulogadung. Menurunnya jumlah permintaan daging tersebut menyebabkan keuntungan pedagang daging menjadi menurun, baik pedagang pengumpul maupun pedagang pengecer. Sementara itu lembaga pemasaran harus menanggung biaya produksi yang tinggi, sedangkan jumlah daging yang dijual hanya sedikit. Dampak dari menurunnya jumlah permintaan daging ini adalah lembaga pemasaran menjadi tidak memiliki kekuatan tawar menawar harga dengan konsumen. Akibatnya harga jual daging ditingkat lembaga pemasaran dapat menjadi rendah sehingga hal ini akan menyebabkan lembaga pemasaran mengalami kerugian. Oleh karena itu maka perlu dianalisis lebih lanjut mengenai ketepatan struktur pasar, perilaku pasar dan keragaan pasar daging sapi dan daging ayam ini sehingga lembaga pemasaran dapat memperoleh saluran pemasaran yang efisien...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
