Judul: Guidelines dan Evaluasi Aplikasi Mobile E-commerce C2C Indonesia berdasarkan Empat Tipe Perspektif Pengguna.
Abstrak: E-commerce merupakan salah satu alternatif berbelanja bagi masyarakat Indonesia. E-commerce terdiri atas beberapa tipe, salah satu yang sedang berkembang dan ramai digunakan adalah tipe C2C yang berbasis marketplace. Perkembangan dari e-commerce didukung dengan meningkatnya penggunaan smartphone di Indonesia sehingga mendorong munculnya e-commerce dalam bentuk aplikasi mobile smartphone. Tujuan dari penelitian ini adalah mengembangkan guidelines untuk mobile e-commerce C2C berdasarkan 4 tipe pengguna serta mengevaluasi 3 aplikasi mobile e-commerce yang ada di Indonesia berdasarkan guidelines tersebut. Pengembangan dilakukan dengan menggunakan 23 literatur terkait dari berbagai sumber hingga dihasilkan 211 guidelines. Guidelines kemudian diberikan kepada expert untuk dilakukan eliminasi guidelines hingga diperoleh 203 guidelines untuk melakukan evaluasi. Evaluasi dilakukan dengan memberikan nilai 1 bila terdapat guidelines dalam aplikasi dan 0 bila tidak ada. Hasil evaluasi menunjukkan Bukalapak memperoleh nilai rata-rata tertinggi hampir pada seluruh tipe guidelines. Secara keseluruhan rata-rata guidelines yang dipenuhi oleh ketiga aplikasi sebesar 73%.

Judul: Usability Guidelines Aplikasi Mobile E-commerce C2C Indonesia Sisi Penjual
Abstrak: C2C (consumer-to-consumer) adalah salah satu tipe e-commerce yang memiliki potensi besar untuk terus berkembang di Indonesia dan memiliki banyak keuntungan jika dilihat dari sisi penjual. Perkembangan e-commerce juga ditunjang oleh tren berbelanja melalui smartphone (mobile commerce). Penelitian ini dimaksudkan untuk mengembangkan usability guidelines pada m-commerce C2C dari sisi penjual. Data yang digunakan dalam penelitian berupa parameter-parameter yang berkaitan dengan usability pada m-commerce bertipe C2C dari sisi penjual. Parameter didapatkan melalui referensi, observasi, dan wawancara. Digunakan 20 referensi yang terdiri dari 1 buku, 5 jurnal, dan 16 penelitian lainnya. Observasi dilakukan dengan menggunakan aplikasi secara langsung sebagai penjual online. Wawancara dilakukan terhadap 6 penjual online. Parameter yang terkumpul kemudian diberikan kepada ahli untuk dilakukan validasi melalui expert judgment. Hasilnya berupa usability guidelines berisi 244 parameter yang terbagi dalam 23 kategori dan 3 tingkatan kepentingan sebagai panduan yang dapat digunakan dalam membangun aplikasi m-commerce C2C sisi penjual yang memenuhi kriteria usability.

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
