Judul: Analisis Kebijakan Lindung Nilai dan Pengaruhnya terhadap Nilai Perusahaan : Studi Empiris pada Bursa Efek Indonesia
Abstrak: The purpose of this study is to investigate the relationship between firm value, financial distress, underinvestment cost , economic exposure and corporate hedging with foreign currency derivatives (FCD) for 186 Indonesian companies listed on the Indonesian Stock Exchange (IDX) over the period 2007-2011. Using data from the annual reports, we find strong evidence linking the decison to hedge and the firm value for the overall sample. Data analysis methods using Structural Equation Modelling (SEM) with the program Linear Structural Relationship (LISREL). This research find that foreign currency hedging is positively correlated with the value of firm. The results suggest that while firm size and the exposure to exchange rate through foreign sales are two important factors determining the decision to hedge, the exposure to exchange rate through foreign sales is the sole factor affecting the extent of hedging. Due to positive economic exposure to the value of the company, the study recommends an increased in productivity export company to improve their performance. And also for the industrial sector that using the external financing in foreign currency should implement hedging policy.

Abstrak: On financial management perspective, corporate goal is to maximize shareholder or corporate value. The purpose of this study was to analyze the effect of institutional ownership (INST), asset structure (FAR), profitability (ROA), and corporate growth (GROWTH) on debt policy. This study used linear and multiple regression analysis. Significant test results of individual parameters (t statistical test) showed that significant value of INST variable 0.058<0.1 (α) and -0.632 (β), FAR 0.097<0.1 (α) and 1.019 (β), ROA 0.043<0.1 (α) and -1.198 (β), and GROWTH 0.064<0.1 (α) and 0.972 (β). The results showed that INST and ROA were significant and negatively affect on debt policies, while FAR and GROWTH were significantly and positively affect on debt policies. Whereas, test result of simultaneous (F statistical test) showed that significant value of 0.010<0.1 (α) and the value of F calculated 4.184>2.184 F table. These results indicated that institutional ownership, asset structure, profitability, and corporate growth had a significant effect on debt policy simultaneously.

Judul: Konstruksi Vektor Rekombinan untuk Mengedit Gen Lanceolate Menggunakan Sistem CRISPR/Cas9 pada Tanaman Tomat (Solanum lycopersicum L.).
Abstrak: Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR associated 9 protein (CRISPR/Cas9) adalah salah satu alat untuk mengedit genom yang baru-baru ini telah berhasil digunakan untuk berbagai tanaman. Tomat (Solanum lycopersicum L.) adalah tanaman model yang ideal untuk menguji sistem CRISPR/Cas9 dalam pengeditan gen karena ketersediaan metodologi transformasi yang efisien dan ketersediaan urutan genom yang berkualitas tinggi, dan mempunyai genom diploid. Tujuan dari penelitian ini adalah membuat konstruksi vektor rekombinan yang membawa oligonukleotida gRNA untuk memutasikan gen lanceolate (LA) pada tanaman tomat. Gen lanceolate merupakan gen yang terlibat dalam pembuatan daun majemuk pada tomat. Supresi gen LA akan membuat daun majemuk berukuran besar berubah menjadi daun tunggal berukuran kecil. Oligonukleotida gRNA berhasil disisipkan ke dalam vektor pRGEB32 sehingga memperoleh vektor rekombinan. Vektor rekombinan ini berhasil diintroduksikan ke dalam Escherichia coli DH5α dan dipindahkan ke dalam Agrobacterium tumefaciens LBA4404 menggunakan metode triparental mating. Koloni PCR mengonfirmasi bahwa oligonukleotida gRNA berhasil disisipkan ke dalam pRGEB32 dan A. tumefaciens LBA4404 mengandung plasmid rekombinan ini.
