Judul: Identifikasi Risiko Pada Jeruk Siam (Citrus Nobilis L) Dengan Pendekatan Failur Mode And Effect Analysis (Fmea) Dan Fishbone Diagrams
Abstrak: Petani di Kabupaten Karo mengalami kendala fluktuasi produktivitas jeruk siam sehingga mengindikasikan adanya suatu risiko. Tujuan penelitian ini untuk menganalisis tingkat risiko pada jeruk siam, mengidentifikasi sumber-sumber risiko prioritas penanganan dan menganalisis tindakan untuk mengendalikan risiko yang dapat dilakukan petani jeruk siam. Analisis risiko menggunakan metode FMEA (Failure Mode and Effect Analysis) dan Fishbone Diagrams. Analisis ini dapat membantu dalam pemilihan tindakan alternatif. Hasil penelitian yang diperoleh pada jeruk siam di Kabupaten Karo terdapat 12 risiko yang menjadi prioritas penanganan. Proses identifikasi penyebab risiko prioritas menggunakan diagram sebab-akibat dengan merinci penyebab kegagalan risiko yang meliputi keadaan alam, hama dan penyakit tanaman jeruk, serta lingkungan bisnis. Alternatif strategi yang dapat dilakukan, pertama, petani jeruk seharusnya melakukan sanitasi lahan dan memasang perangkap lalat buah. Kedua, petani perlu menerapkan pupuk organik hasil fermentasi dan melakukan perawatan tanaman. Ketiga petani seharusnya bergabung dengan kelompok tani untuk memperoleh informasi pasar.

Abstrak: Udang, kepiting dan tuna olahan Indonesia merupakan produk potensial yang menempati urutan enam besar ekspor tertinggi dunia. Namun, ekspor udang, kepiting dan tuna olahan masih lebih rendah daripada ikan beku dan segar. Tujuan penelitian ini menganalisis posisi daya saing udang olahan (2005-2011), kepiting dan tuna olahan (2005-2012) menggunakan metode Revealed Comparative Advantage (RCA) dan Export Dynamic Product (EPD), serta menganalisis faktor yang memengaruhinya menggunakan panel data statis. Hasil RCA, ikan olahan memiliki rata-rata RCA > 1 kecuali udang dan kepiting olahan di Jepang. Hasil EPD, ikan olahan yang berdaya saing baik (Rising Star) yaitu udang olahan di semua negara tujuan ekspor, kepiting olahan di USA, Kanada, Australia, dan tuna olahan di Saudi Arabia dan UK. Faktor positif yang memengaruhi daya saing udang olahan yaitu produksi udang, volume dan harga ekspor, kepiting olahan yaitu nilai tukar, volume dan harga ekspor, tuna olahan yaitu volume dan harga ekspor. Faktor yang berpengaruh negatif terhadap daya saing udang olahan yaitu GDP Indonesia dan nilai tukar, kepiting dan tuna olahan yaitu GDP Indonesia.

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
