Judul: Uji Kinerja Alat Elektroni Logbook (E-Logbook) perikanan.
Abstrak: Perairan laut Indonesia memiliki potensi sumber daya ikan dan keanekaragaman hayati yang tinggi. Potensi tersebut merupakan suatu modal yang seharusnya dapat membangun kesejahteraan masyarakat, khususnya nelayan Indonesia. Menurut sistem informasi data statistik kelautan dan perikanan, Kementrian Kelautan dan Perikanan (www.statistik.kkp.go.id), volume produksi perikanan tangkap di laut Indonesia tahun 2011 mencapai 5.034.679 ton. Logbook perikanan sangat diperlukan dalam pengumpulan data hasil tangkapan ikan, yakni pencatatan jenis tangkapan ikan, jumlah tangkapan ikan, posisi/lokasi tangkapan ikan dan waktu tangkapan. Namun, program logbook perikanan tersebut memiliki kekurangan dari segi kontinuitas pencatatan data karena sangat tergantung pada kondisi observer di lapangan. Workshop Akustik dan Instrumentasi Kelautan, Departemen Ilmu dan Teknologi Kelautan, Fakultas Perikanan dan Ilmu Kelautan, Institut Pertanian Bogor telah membuat alat elektronik logbook perikanan (e-logbook). Pengujian kinerja e-logbook perlu dilakukan untuk mengukur ketepatan dan ketelitian dalam sistem peralatan tersebut. Pengujian alat elektronik logbook (e-logbook) di lapangan diharapkan menjadi tolak ukur keberhasilan sistem kerja alat tersebut. Hal tersebut dapat menjadi rekomendasi penggunaan e-logbook dalam program pencataan data tangkapan ikan di Indonesia menggantikan sistem logbook manual yang sekarang masih digunakan.

Judul: Persepsi Nelayan dan Petugas Syahbandar terhadap E-Logbook Penangkapan Ikan di Pangkalan Pendaratan Ikan Karangsong Indramayu.
Abstrak: Permasalahan penerapan e-logbook di PPI Karangsong adalah tingkat partisipasi nelayan yang dinilai masih sangat sedikit yaitu 17.3% dari sekitar 300 unit kapal berukuran di atas 30 GT yang izinnya telah diterbitkan oleh Kementerian Kelautan dan Perikanan (KKP). Tujuan penelitian ini adalah mengidentifikasi persepsi nelayan dan petugas syahbandar terhadap e-logbook penangkapan ikan serta merekomendasikan strategi dalam pemanfaatan e-logbook penangkapan ikan di PPI Karangsong. Penelitian dilakukan di PPI Karangsong menggunakan metode survei. Analisis yang digunakan adalah analisis deskriptif dan analisis SWOT. Hasil penelitian menunjukkan bahwa persepsi nelayan terhadap e-logbook penangkapan ikan berdasarkan tiga aspek yaitu aspek individu, aspek teknis serta aspek kelembagaan didominasi oleh persepsi nelayan yang rendah, dan persepsi petugas syahbandar terhadap e-logbook dianggap belum berjalan efektif. Beberapa strategi yang direkomendasikan dalam pemanfaatan e-logbook di PPI Karangsong diantaranya adalah 1) penambahan fitur yang dibutuhkan nelayan serta memperbolehkan pengisian manual hingga semua sarana dan prasarana lengkap dan berfungsi; 2) pengadaan back up data oleh petugas yang terintegrasi dengan Sistem Informasi Logbook Penangkapan Ikan (SILOPI); 3) pengadaan pelatihan secara berkala dan pengecekan secara langsung di lapangan terkait penerapan e-logbook penangkapan ikan oleh petugas serta peningkatan jumlah petugas syahbandar di PPI Karangsong; 4) peningkatan kerjasama antara lembaga penerbitan e-logbook dengan lembaga penyusun peraturan perundang-undangan terkait e-logbook.

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
