Judul: Pemanfaatan Friendster sebagai media komunikasi antar pribadi melalui jaringan sosial dunia maya:
Abstrak: Penelitian ini bertujuan ingin mengetahui dan menganalisis profil anggota friendster, akses media friendster, aktivitas komunikasi, jaringan sosial, pemanfaatan friendster sebagai media komunikasi, dan hubungan antara profil anggota, akses media friendster, aktivitas komunikasi dengan jaringan sosial, serta hubungan jaringan sosial dengan pemanfaatan friendster. Penelitian dilaksanakan di jalan Babakan Raya I Drarnaga, Kabupaten Bogor. Kuesioner diberikan kepada anggota friendster yang masuk dalam jaringan peneiti dan diedarkan di wamet "Qlobal Internet" Pengambilan dan pengumpulan data dilaksanakan pada bulan Maret 2009. Penelitian di desain dengan metode survey. Populasi adalah anggota eiendster yang berada di Kabupaten Bogor tepatnya di jl Babakan Raya I Dramaga. Pengambilan sampel menggunakan metode purposive sampling dan jumlah sampel50 orang. Data dianalisis secara deskriptif dengan perbitungan persentase dan tabel distribusi. Analisis hubungan menggunakan analisis rank Spearman untuk data ordinal dan Chi-square untuk data nominal dengan alat bantu statistik SPSS 13 for Windows.

Judul: Pengamatan terhadap aktivitas pengguna jejaring media sosial Facebook dengan Statistika deskriptif
Abstrak: Social network Facebook is the social network that exist long enough. Currently, Facebook is the social network with the most users in the world. More than 80% of internet users in the world have a Facebook account. In Indonesia, Facebook is the social network with the most users too. Percentage of internet users in Indonesia that have a Facebook account is over 90%, and more than half are active users. Result of observation over some Facebook account show that 45% users became passive in the last two years (2013-2014). Down rate in 2014 is higher than 2013. The emergences of various new social network with different services is suspected causes many Facebook users became passive and start using other social network.

Judul: Gene Editing  of Two Cyanide Synthesis-related Genes in Cassava using CRISPR/Cas9
Abstrak: Cassava (Manihot esculenta) contain toxic quantities of cyanogenic glucoside. Reducing the potentially toxic cyanogenic glucoside levels in cassava could be achieved by gene editing through Clustered Regularly Interspaced Short Palindromic Repeats – CRISPR associated protein 9 (CRISPR/Cas9), a high- precision genome editing technique in plants. Two cassava UDP- glucosyltransferase (UGT) paralogs, UGT85K4 and UGT85K5, are the genes catalyzing the synthesis of cyanogenic glucosides in plants. The study aimed to construct the CRISPR/Cas9 recombinant vector carrying single guide RNA (sgRNA) to edit UGT85K4 and UGT85K5 genes, and transform sgRNA CRISPR/Cas9 construct into KU50 cassava calli. Five sgRNAs were designed, considering the on/off target efficiency score and GC content. Those sgRNAs were ligated into pRGEB32 plasmid and introduced to competent Escherichia coli DH5a. The PCR colony and DNA sequencing were performed to verify the sgRNA insert. The amplicons showed the expected band size of recombinant vector (180 bp). Based on sequencing results, only one sgRNA was successfully ligated into the plasmid that will be used to edit the UGT85K5 gene. The sgRNA CRISPR/Cas9 construct in pRGEB32 plasmid was successfully transformed into Agrobacterium tumefaciens and introduced into KU50 cassava calli through co-cultivation. The overgrowth of Agrobacterium occurred after the co-cultivation phase.
