Judul: Struktur Genetika Populasi Ikan Malalugis (Decapterus macarellus) di Perairan Sekitar Pulau Sulawesi Berdasarkan Mt-DNA Marker
Abstrak: Studies on genetic diversity of Malalugis (Decapterus macarellus) has been undertaken around Sulawesi to obtain population genetic structure of the study area. The study was based on RFLP analysis of mitochondrial genome DNA extracted from fish tissue (meat, fins). Fish samples collected from several populations of small-scale fisheries captured in several locations around Sulawesi. The results showed that the genetic diversity obtained by including low, ie between 0 to 0.3698. Provided two major groups in the population structure Malalugis fish in the waters around Sulawesi Island, namely: the first group is represented by a population of Makassar Strait,Bone Bay, Flores Sea, Banda Sea, Tolo Bay, Molucca Sea and Tomini Bay and the second group is represented by the Celebes Sea population. The population of the Bone Bay, Flores Sea, Banda Sea, Tolo Bay and Molucca Sea has a very close kinship, so that probably originated from the same stock. In the population there Tomini Bay locals, because there is little difference with adjacent populations (Maluku Sea and Banda Sea).

Judul: Variasi geografik dalam struktur genetik populasi  ikan Kakap merah, Lutjanus malabaricus  (Lutjanidae) dan interaksi lingkungan di Laut Jawa
Abstrak: Penelitian tentang variasi geografik dalam struktur genetik populasi ikan Kakap merah (Lutjanus malabaricus, LUTJANIDAEd)a n interaksinya dengan kondisi perairan Laut Jawa berdasarkan karakter polimorfisme yang terdapat pada region control mtDNA (D-loop) dan kajian tentang kondisi lingkungan perairan Laut Jawa. Penelitian bertujuan untuk menentukan unit-unit stok ikan yang dieksploitasi guna keperluan pengelolaan perikanannya secara tepat di wilayah ini. Karakter polimorfisme diperoleh dari analisis RFLP (Restriction Fragment Length Polymorphism) terhadap sekuen yang teramplifikasi dengan menggunakan tiga jenis enzym restriksi (Alu I, Nla III dan Xba I). Genom mtDNA'diekstrak dari daging ikan contoh yang dikumpdkan di lapangan dan mewakili lima populasi ikan di Laut Jawa, yaitu populasi Blanakan, Batang, Banyutowo, Tuban dan Kotabaru. Amplifikasi genom dilakukan melalui proses PCR (Polymerase Chain Reaction) dengan menggunakan primer spesifik TDKD & PRO.

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.
