Judul: Pembentukkan Portofolio Optimal Pembiayaan Pada Unit Usaha Syariah Pt Bank Xyz
Abstrak: Unit Usaha Syariah (UUS) PT Bank XYZ merupakan perusahaan yang bergerak di bidang jasa dengan fungsi utama menghimpun dan menyalurkan dana kepada masyarakat yang membutuhkan dana. Tingginya risiko terhadap pembiyaan memaksa UUS PT Bank XYZ untuk membentuk portofolio pembiayaan yang optimum.Tujuan penelitian ini adalah untuk menganalisis kondisi portofolio pembiayaan dan pendapatan bagi hasil portofolio pembiayaan, menganalisis pembentukan portofolio pembiayaan optimum.Penelitian menggunakan metode Markowitz.Semakin tinggi penyaluran dana yang diberikan akan mengakibatkan peningkatan risiko pembiayaan. Dengan menggunakan metode Markowitz diperoleh kombinasi portofolio pembiayaan optimum berdasarkan jenis pembiayaan dengan meminimumkan risiko portofolio pembiayaanmenjadi 0.1261 dengan nilai portofolio pembiayaan sebesar 0.0649 apabila UUS PT Bank XYZ memprioritaskan pemberian pembiayan pada jenis pembiayaan murabahah sebesar 34.06 persen, pembiayaan ijarah sebesar 20.98 persen, dan pembiayaanmusyarakah dan MMQ sebesar 22.48 persen.

Judul: Analisis Kebijakan Investasi dalam Pembentukan Portofolio Optimum Studi Kasus Pada PT Asuransi XYZ Indonesia
Abstrak: Arah investasi perusahaan asuransi mengacu pada investment policy perusahaan serta Peraturan Menteri Keuangan dan Otoritas Jasa Keuangan. Saat ini PT XYZ memperoleh imbal hasil portofolio investasi yang lebih rendah dari risk free, sehingga dibutuhkan pembentukan portofolio optimum dan analisis kebijakan investasi untuk meningkatkan imbal hasil dari portofolionya. Tujuan penelitian ini ialah (1) menganalisis kinerja portofolio investasi perusahaan sesuai dengan investment policy perusahaan, (2) membentuk portofolio optimum dengan membandingkan kebijakan pemerintah dengan investment policy perusahaan, dan (3) meimplementasikan peraturan OJK Nomor 1/POJK.05/2016 tentang Investasi pada Surat Berharga Negara (SBN). Portofolio yang dianalisis terdiri dari deposito berjangka, obligasi, reksa dana dan SBN dengan data bulanan pada periode 2014- 2015 menggunakan Minimum-Variance Portfolio, Single Model Index, dan tabulasi acak. Hasil analisis menunjukkan bahwa batasan kebijakan pemerintah memberikan expected return yang lebih tinggi dengan risiko yang lebih rendah dibandingkan dengan batasan investment policy perusahaan, sehingga PT XYZ sebaiknya mengubah investment policy perusahaan dan portofolio investasinya.

Judul: Development of DNA Vaccine Encoding Glycoprotein of Koi Herpes Virus Using Local Isolate.
Abstrak: The aim of this research was to develop DNA vaccine of Koi Herpesvirus in carp. Glycoprotein gene originated from ORF 25 KHV virus that is 1.8 kbp in size, is a potential gene in DNA vaccine construction. The sequencing and similarity analysis of the gene using BLAST software showed that this gene is a GP25 gene and was found to be very similar (99%) to GP25 of KHV virus from the USA and Israel. When this GP25 gene was ligated with pGEMT Easy (pT, 3 kbp in size) vector, plasmid size was increasing up to 5 kb. Following this, a digestion of pT-GP25 plasmid using Sal I enzyme was applied resulted in a GP25 fragment (1.8 kbp). Subsequently, pAct-D6 with a size of 8.5 kbp was also cut using the same enzyme to eleminate a D6 gene with a size of 1.6 kbp. GP25 gene was then ligated with pAct resulted a pAct-GP25 plasmid with a size of 8.8 kbp. As there was only one restriction site applied, ligation can be occurred in two different directions. Thus, in order to determine the plasmid with the desired direction PCR analysis was carried out, and plasmid with the right direction was the one that sized approximately 2.1 kbp (no. 6, 17 and 20). High level of GFP gene expression was detected in all tissues analyzed, i.e. kidney, gil, spleen, and muscle 24 hours after injection which indicated that β-actin promoter of Japanese medaka could be active in common carp. Although not as high as on 24 hours, expression was still detected until day 7 and disappeared after day 28 post injection indicating that pAct-GFP can be remained and β-actin promoter of Japanese medaka can be active in muscle, gills and kidney at least a week after injection. The result of RT-PCR analysis on pAct-GP25 injected common carp showed that GP25 gene expression can be detected 14 days after injection in all tissues observed. The expression level differences between GFP and GP25 genes possibly related to the primer sensitivity on annealing process to cDNA template and the size of PCR targeted DNA fragment, as smaller PCR targeted product will be easier to be amplified than a bigger one. The length of PCR targeted DNA with GP25 primer was 1.8 kbp whereas GFP gene was 0.6 kbp.The challenge test on common carp results showed that all unvaccinated and negative control (not infected with KHV) was alive until the end of the experiment. Whereas, the survival of fish vaccinated with a dose of 12.5 was ranged from 60.9 and 96.7%. In relation to the activity of β-actin promoter that was used in this DNA vaccine, gene expression was occured 24 hours after vaccination and remained until 2 weeks. The control fish that was not injected by GP25 showed no GP25 expression either in the observed tissues or organs and resulted in a lower survival, i.e. 23.3%. The challenge test results has indicated that the fish vaccinated with GP25 at doses of 7.5 and 12.5 μg/100μL were able to produce KHV glycoprotein in their body which would be
