Judul: Sistem Bagi Hasil Nelayan Purse seine di Pangkalan Pendaratan Ikan (PPI) Pasongsongan Kabupaten Sumenep.
Abstrak: Patron-klien adalah hubungan antara dua komunitas atau individu yang memiliki perbedaan dari segi status, kekuasaan maupun penghasilan,. Sistem bagi hasil yang terlaksana di PPI Pasongsongan Kabupaten Sumenep masih berdasarkan kebiasaan yang berlangsung secara turun temurun tanpa adanya perjanjian khusus yang tertulis. Penelitian ini bertujuan untuk mengidentifikasi sistem bagi hasil antara pekerja dan juragan dari suatu kelompok nelayan purse seine, serta mengidentifikasi pola hubungan nelayan purse seine di PPI Pasongsongan Kabupaten Sumenep. Penelitian dilakukan dengan metode survey dan analisis data menggunakan metode deskriptif. Teknik pengumpulan data dilakukan melalui wawancara yang dilengkapi dengan kuesioner, serta pengambilan sampel menggunakan metode purposive sampling. Berdasarkan penelitian yang telah dilakukan, hubungan nelayan ditinjau dari sisi ketergantungan antara nelayan penggarap dengan nelayan pemilik/juragan dapat digolongkan sebagai dyadic contract. Sistem bagi hasil yang diterapkan di PPI Pasongsongan Kabupaten Sumenep yaitu 50% untuk nelayan pemilik dan 50% untuk nelayan penggarap.

Judul: Kelembagaan Patron-Klien dalam Masyarakat Nelayan di Cilauteureun Pameungpeuk Kabupaten Garut
Abstrak: Pola hubungan patron-klien dalam masyarakat nelayan di Cilauteureun dapat dilihat dari keterikatan nelayan buruh kepada nelayan pemilik, mulai dari biaya operasional melaut sampai biaya untuk kebutuhan sehari-hari. Praktek bagi hasil pada nelayan di Cilauteureun terjadi berdasarkan adat istiadat atau sudah terjadi secara turun temurun dan belum menggunakan perjanjian tertulis antara nelayan buruh dengan nelayan pemilik. Penelitian ini bertujuan untuk mengindentifikasi hubungan patron-klien dan sistem bagi hasil perikanan tangkap yang terjadi di daerah tersebut. Metode yang digunakan dalam penelitian ini adalah studi kasus dengan responden yang ditentukan dengan teknik purposive sampling. Berdasarkan penelitian yang telah dilakukan, hubungan nelayan yang terjadi di masyarakat nelayan Cilauteureun dapat digolongkan ke dalam hubungan yang bersifat resiprositas umum. Sistem bagi hasil yang diterapkan oleh nelayan di Cilauteureun yaitu bagi hasil 40% untuk nelayan pemilik dan 60% untuk nelayan buruh. Sistem bagi hasil ini sudah sesuai dengan pembagian yang terdapat dalam UU Nomor 16 Tahun 1964.

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
