Judul: Peranan peraturan pemerintah dalam bidang perikanan terhadap pendapatan nelayan dan kelestarian sumberdaya perikanan laut
Abstrak: Penelitian ini bertujuan untuk memperoleh gambaran mengenai pendapatan nelayan dan keadaan sumberdaya akibat adanya peraturan-peraturan perikanan yang dikeluarkan oleh Pemerintah. Penelitian dilaksanakan pada bulan Juli 1981 sampai bulan Januari 1982, di Gebang Ilir Kabupaten Cirebon, Jawa Barat.Data mengenai aspek sosial ekonomi diperoleh dari wawancara dengan 80 orang responden yang meliputi Nelayan sampel sebagai responden (juragan), yang diambil hasil 6 jenis alat penangkap. dibatasi pada nelayan pemilik alat secara acak. Data biologis diperoleh dari hasil pendaratan ikan oleh nelayan di tempat pelelangan ikan (TPI), dan peng- amatan dilakukan dua kali dalam seminggu selama tiga bulan. Pengujian dan analisis data dilakukan dengan menggunakan analisis sidik ragam. Uji-t dan analisis deskriptif. Hasil analisis pengaruh alat penangkap terhadap pendapatan kotor, biaya produksi dan pendapatanbersih serta outpu-input ratio memberikan pengaruh yang nyata. Dilihat dari pendapatan bersih, alat penangkap pancing merupakan alat penangkap yang paling tinggi pendapatan bersihnya, sedangkan jika dilihat biaya produksinya alat penangkap bagan tetap paling rendah dibandingkan dengan alat penangkap lainnya. Penggunaan motor pada perahu dapat meningkatkan pendapatan bersih nelayan, walaupun biaya produksinya jauh lebih besar jika dibandingkan dengan perahu layar. Banyaknya ikan muda yang tertangkap merupakan ancaman terhadap kelestarian sumberdaya perikanan laut, dan kecenderungan makin meningkatnya jumlah ikan muda yang tertangkap disebabkan antara lain oleh makin banyaknya alat penangkap yang dioperasikan dan makin intensifnya operasi penangkapan. Disarankan agar dilakukan penelitian mengenai potensi sumberdaya perikanan laut terutama potensi perairan pantainya, khususnya perairan pantai Cirebon.

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
