Judul: Pengendalian Pemanfaatan dan Survei Ikan Napoleon (Cheilinus undulatus Ruppell, 1835) di Kecamatan Salawati Utara Kabupaten Raja Ampat
Abstrak: Tingginya nilai ekonomi ikan Napoleon (Cheilinus undulatus) di pasar China/Hong Kong menyebabkan spesies ini dieksploitasi secara terus-menerus, dan Indonesia adalah salah satu negara pengekspor terbanyak. Banyak hasil studi yang melaporkan populasinya di alam semakin berkurang, sehingga IUCN menetapkan spesies ini dalam kategori terancam punah, dan pada tahun 2004 berdasarkan kesepakatan negara-negara anggota CITES, ikan ini dimasukkan ke dalam daftar appendiks II CITES. Sejak tahun 1980-an, ikan Napoleon telah dieksploitasi di Kabupaten Raja Ampat untuk perdagangan ikan hidup dan terindikasi sebagian besar dilakukan secara ilegal yaitu pelanggaran melebihi jumlah kuota penangkapan tahunan yang diperbolehkan dan ukuran yang ditangkap tidak sesuai dengan ketentuan yang berlaku. Tujuan penelitian adalah: 1) Menganalisis kondisi kelimpahan ikan Napoleon di Kecamatan Salawati Utara, 2) Menganalisis status pemanfaatan ikan Napoleon di Kabupaten Raja Ampat, dan 3) Menentukan skala prioritas pengendalian pemanfaatan ikan Napoleon di Kabupaten Raja Ampat. Penelitian dilakukan pada bulan Juli hingga September 2016. Survei kelimpahan menggunakan metode Underwater Visual Census (UVC) dengan Global Positioning System (GPS) dilakukan di wilayah Perairan Kecamatan Salawati Utara. Status pemanfaatan dianalisis dengan penilaian Non-Detriment Finding (NDF). Penentuan skala prioritas pengendalian pemanfaatan menggunakan model Analytical Hierarchy Process (AHP). Survei di Kecamatan Salawati Utara dilakukan di sekitar Pulau Jefman, Pulau Matan, Pulau Kasimraja dan Perairan Desa Wamega. Nilai kelimpahan yang diperoleh adalah 6.61 ind./ha setelah melakukan survei sepanjang 8.096 km. Berdasarkan analisis, status pemanfaatan terhadap populasi ikan Napoleon di Kabupaten Raja Ampat pada tingkatan cukup aman (nilai: 3.23 ≈ 3). Hasil penilaian AHP, kriteria yang paling penting untuk melaksanakan upaya pengendalian pemanfaatan ikan Napoleon di Kabupaten Raja Ampat adalah sumberdaya ikan lestari, sedangkan urutan prioritas alternatif adalah: 1) Sosialisasi kepada nelayan/pengusaha, 2) Pengawasan, 3) Survei kelimpahan secara berkala, dan 4) Penerapan lalu lintas perdagangan melalui bandara.

Judul: Analisis Keragaman Genetik Ikan Napoleon (Cheilinus undulatus) di Kepulauan Seribu Berdasarkan DNA Mikrosatelit
Abstrak: Napoleon wrasse is one of many fish that belongs to highly commercial category on Fishing Industry. In addition, napoleon wrasse is well known as one of the key predator species which play an important role for the ecology and sustainability of coral reef ecosystems. The purpose of this study was to analyze genetic diversity level of napoleon wrasse at Kepulauan Seribu, and recognize the conservation and trading status of napoleon wrasse. Sample extraction using DNeasy blood and tissue kit by Qiagen. Amplification of microsatellite loci gene by PCR using primer of A3, A65, and T63 loci. Stages of annealing was carried out at 57 °C on A65 primer, 58 °C on T63 primer, and 56 °C on A3 primer, for 30 seconds and 30x cycle. Genetic diversity result showing that the average values of Hobs from 3 loci that being used is 0.608. The highest PIC value was found on T63 loci primer, with 0.588 PIC value and 7 numbers of alleles were amplified. Based on IUCN, Napoleon wrasse was listed on endangered status and listed on Appendix II of trading status by CITES.

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
