Judul: Hubungan Pengembangan Wisata Dengan Strategi Nafkah Dan Taraf Hidup Rumah Tangga Nelayan Desa Karimunjawa
Abstrak: Wisata telah berkembang menjadi salah satu komoditi penyumbang devisa bagi negara selain tambang dan minyak bumi. Jenis wisata yang berkembang di Indonesia adalah ekowisata dan pariwisata. Pengembangan wisata yang baik tidak hanya fokus pada keseimbangan alam dan tingkat perekonomian, tapi juga kesejahteraan masyarakat lokal. Nelayan merupakan bagian dari masyarakat lokal dalam penyelenggaraan wisata pesisir dan pulau-pulau kecil. Pengembangan wisata secara langsung maupun tidak langsung akan memengaruhi strategi nafkah nelayan. Penerapan strategi nafkah adalah bentuk adaptasi nelayan terhadap perubahan ekologis maupun sosiologis akibat pengembangan wisata. Bentuk strategi nafkah yang dilakukan juga ditentukan oleh karakteristik nelayan, seperti stratifikasi kelas nelayan. Kepemilikan modal dalam bentuk kapal akan menentukan seberapa jauh strategi nafkah yang akan diterapkan. Penerapan strategi nafkah tersebut tidak hanya dilakukan sebagai upaya untuk mempertahankan hidup, tapi juga meningkatkan taraf hidup keluarga nelayan.

Judul: Dampak Pengembangan Ekowisata Bahari terhadap Ekologi dan Sosial-Ekonomi Nelayan (Kasus Desa Karimunjawa, Kecamatan Karimunjawa, Kabupaten Jepara, Provinsi Jawa Tengah)
Abstrak: Penelitian ini dilakukan di Desa Karimunjawa, Kecamatan Karimunjawa, Kabupaten Jepara yang bertujuan untuk: (1) Mengetahui dampak ekowisata bahari terhadap ekosistem masyarakat setempat; (2) Mengetahui dampak perubahan ekosistem tersebut terhadap struktur ekonomi dan sosial nelayan akibat adanya pengembangan wisata; dan (3) Mengetahui pola adaptasi ekonomi yang dilakukan oleh komunitas nelayan terhadap perubahan ekologi dan pengembangan pariwisata tersebut. Penelitian ini menggunakan data kuantitatif dengan kuesioner yang didukung oleh data kualitatif melalui observasi, wawancara mendalam dan penelusuran dokumen terkait dengan pembahasan dalam penelitian ini. Responden dari penelitian adalah 50 orang nelayan yang diperoleh melalui teknik penarikan sampel aksidental. Responden ini terbagi menjadi dua, yaitu 25 orang responden non pariwisata dan 25 orang nelayan pariwisata.

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
