Judul: Gejala modernisasi dan kelembagaan bagi hasil: suatu kajian perubahan sosial atas kasus pada kelompok-kelompok kerja nelayan tangkap di Kabupaten Lamongan Jawa Timur
Abstrak: Lokasi yang dijadikan obyek pengamatan adalah dua kecamatan, yaitu Kecamatan Brondong dan Paciran, di Kabupaten Lamongan (Jawa Timur). Unit analisisnya adalah kelompok-kelompok kerja nelayan tangka, yang dibedakan atas jenis teknologi dan modal yang digunakan untuk perasi miyang. Indikasi adanya gejala modernisasi ditelusuri dari berkenbangnya peradaban ekonomi pasar ("uang"), penggunaan teknoligi peralatan tangkap yang relatif tinggi, dan permodalan yang besar untuk operasi miyang. Penganalisaan data dilakukan dengan metod kuantitatif, yaitu dengan bantuan analisa statistik (Uji T-student); dan kualitatif, yaitu dengan pendekatan ideografis dan verstehen. Penggnaan metoda tadi ditekankan untuk mengkontraskan perbandingan secar penampang liņtang (cross section) atas gejala-gejala tertentu yang terjadpada dua katagori kelompok kerja nelayan; purseseine dan non- purseeine…dst

Judul: The Modernizations of Capture Fisheries and Fishers Welfare Level in Pangandaran Regency
Abstrak: Modernisasi perikanan merupakan peralihan cara-cara tradisional dengan teknologi yang lebih modern. Terdapat beberapa tahapan modernisasi perikanan tangkap yang dialami oleh para nelayan, seperti jumlah modal, kekuatan mesin, ukuran GT (gross ton), dan harga alat tangkap. Penelitian ini bertujuan untuk menganalisis bagaimana modernisasi perikanan tangkap yang terjadi di nelayan, menganalisis tingkat kesejahteraan nelayan, dan menganalisis hubungan tingkat kemodernan armada tangkap dan tingkat kesejahteraan nelayan. Metode penelitian yang digunakan adalah pendekatan kuantitatif melalui metode survei dengan didukung data kualitatif melalui wawancara mendalam dan studi literatur. Penentuan responden penelitian sebanyak 60 orang dengan menggunakan teknik bola salju. Hasil penelitian menunjukkan terdapat empat periode proses modernisasi; dan pada saat ini kemodernan perikanan tangkap para nelayan di Pangandaran berada pada tingkat rendah, sedangkan tingkat kesejahteraan nelayan di Kabupaten Pangandaran terkategori sedang. Selanjutnya, terdapat hubungan yang kuat dan sangat nyata antara tingkat kemodernan perikanan tangkap dan tingkat kesejahteraan nelayan di Kabupaten Pangandaran. Adanya modernisasi berpengaruh terhadap perubahan sosial masyarakat pesisir, dimana semakin modernnya suatu armada tangkap, lambat laun dapat mengubah kehidupan sosial masyarakat nelayan itu sendiri khususnya pada tingkat kesejahteraan nelayan., Modernization of fisheries is the transition of traditional ways with more modern technology. There are several periods of modernization, such as the amount of capital, capacity of machine, size of gross ton, and fishing gear price. This research aims to analyze how the modernization of capture fisheries occurs in the fishers, to analyze the level of fishers welfare, and to analyze the relationship between the modernity level and fishers welfare level. The research used survey methods with quantitative approach were supported by qualitative data through in-depth interviews and literature studies. The respondents were 60 people with snowballing sampling. The results showed that there were four periods of the modernization process; and at this time the modernity of the fisher's capture fisheries in Pangandaran is at a low level, then the fishers welfare level in Pangandaran Regency is in the moderate category, and there was a significant correlation between the level of modernization capture fisheries and fishers welfare level. Modernization has an effect on social change in fishers, more modern a fishing fleet is, it can gradually change the social life of the fishers, especially at the level of fishers welfare.

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
