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: 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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
