Judul: Pengaruh pengelolaan sumber daya pesisir secara kolaboratif terhadap kondisi sosial ekonomi nelayan Desa Gili Indah
Abstrak: Ko-manajemen yang berhasil dapat menciptakan keseimbangan tiga pilar konservasi, yaitu sosial, ekonomi dan ekologi. Terdapat dua aktor penting dalam implementasi ko-manajemen, yaitu masyarakat dan pemerintah. Pengelolaan sumber daya pesisir berbasis masyarakat di Desa Gili Indah diatur oleh institusi awig-awig. Pengelolaan sumber daya pesisir rezim pemerintah direpresentasikan oleh Balai Kawasan Konservasi Perairan Nasional TWP Gili Matra. Kolaborasi yang terjadi diantara kedua institusi tersebut meliputi kesamaan batas wilayah pengelolaan, aturan yang sesuai dengan kondisi masyarakat lokal, partisipasi masyarakat secara kolektif, mekanisme konflik dan pengakuan pemerintah. Sementara terdapat perbedaan pengelolaan sumber daya berupa pemantauan/monitoring, penetapan sanksi dan jejaring kolaborasi dengan pihak luar. Pengelolaan sumber daya secara kolaboratif memberikan pengaruh kepada aspek sosial berupa pengakuan awig-awig, persepsi keberlanjutan awig-awig, kesadaran kelestarian lingkungan, konflik dan stratifikasi sosial. Pengelolaan sumber daya secara kolaboratif juga memberikan pengaruh kepada aspek ekonomi yang meliputi mata pencaharian, tingkat pendapatan dan program kemitraan.

Judul: Kajian Pengelolaan Sumberdaya Perikanan (Co-Fish Project) Dan Dampaknya Terhadap Keadaan Sosial-Ekonomi Masyarakat Di Kabupaten Bengkalis
Abstrak: Sebagian besar penduduk di Kabupaten Bengkalis tempat dilaksanakannya Co-Fish Project pada tahun 1998-2005 bermata pencaharian sebagai nelayan, dengan kondisi sosial-ekonomi relatif rendah dan sering terjadi konflik dalam masyarakat. Penelitian ini bertujuan memerikan pelaksanaan Co-Fish Project dan mengkaji perubahan kondisi sosial-ekonomi masyarakat nelayan, termasuk kearifan lokal dan konflik yang terjadi, dan merumuskan arah pengembangan pengelolaan sumberdaya perikanan. Metode analisis yang digunakan meliputi analisis deskriptif, uji beda dan analisis hierarki proses (AHP). Hasil analisis menunjukkan bahwa Co-Fish Project tidak berhasil memperbaiki kondisi sosial-ekonomi masyarakat. Untuk perbaikan pengelolaan sumberdaya perikanan dirasa perlu adanya campur tangan pemerintah dalam pembangunan sarana dan prasarana yang diperlukan, dan dalam meningkatkan partisipasi masyarakat melalui peningkatan peran dan fungsi kelembagaan yang diperlukan guna tercapainya perbaikan kondisi sosial-ekonomi masyarakat Kabupaten Bengkalis.

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
