Judul: Analisis Perilaku Konsumen Dalam Proses Keputusan Pembelian Laptop (Studi Kasus Mahasiswa Strata 1 Institut Pertanian Bogor)
Abstrak: Produsen laptop sangat memerlukan pengetahuan yang mendalam mengenai konsumennya dalam menghadapi tingginya persaingan. Pengetahuan ini mendorong upaya pemasaran yang dilakukan menjadi terfokus dan efektif, sehingga untuk itu produsen perlu mengetahui tahapan-tahapan dalam proses keputusan pembelian konsumennya serta mengetahui faktor-faktor yang mempengaruhi keputusan pembelian laptop tersebut. Tujuan dari penelitian ini adalah untuk Menganalisis proses keputusan pembelian laptop oleh mahasiswa dan Menganalisis variabel-variabel yang mendorong pembelian laptop oleh mahasiswa strata 1 Institut Pertanian Bogor. Analisis data menggunakan analisis deskriptif untuk menganalisis proses keputusan yang dilakukan oleh mahasiswa dan analisis diskriminan untuk melihat variabel-variabel yang mendorong pembelian laptop. Proses keputusan pembelian laptop yang dilakukan oleh mahasiswa pada tahap pengenalan kebutuhan memiliki motivasi pembelian untuk mempermudah dokumentasi data, manfaat utama sebagai komputer portabel kemudian pada tahap pencarian informasi yaitu sumber dan media informasi yang paling berpengaruh adalah teman. Tahap evaluasi alternatif yaitu pertimbangan awal pemilihan laptop adalah pada harga laptop dan indikator kualitas pada fitur laptop. Tahap proses pembelian yang menjadi alasan pemilihan merek laptop favorit adalah karena harganya terjangkau. Tahap terakhir yaitu perlaku pasca pembelian diperoleh informasi bahwa tingkat kepuasan mahasiswa adalah puas, sikap loyalitas mahasiswa jika merek laptop favorit tidak tersedia akan mencari tempat penjualan lain dan sikap loyalitas mahasiswa ketika merek laptop favorit mengalami kenaikan harga akan membeli laptop lain yang lebih murah. Variabel manfaat adalah variabel yang dipersepsikan mahasiswa sebagai variabel yang mendorong dalam pembelian laptop merek Lenovo, variabel kemudahan dan harga dipersepsikan oleh mahasiswa sebagai variabel yang mendorong dalam pembelian laptop Dell. Variabel merek adalah variabel yang dipersepsikan mahasiswa sebagai variabel yang mendorong dalam pembelian laptop merek Lenovo, variabel ukuran adalah variabel yang dipersepsikan mahasiswa sebagai variabel yang mendorong dalam pembelian laptop merek Advan. Variabel spesifikasi dan warna adalah variabel yang paling mendorong mahasiswa dalam pembelian laptop merek Dell. Variabel wiraniaga dipersepsikan sebagai variabel yang mendorong dalam pembelian laptop merek Advan dan Compaq, variabel pendapatan dipersepsikan sebagai variabel yang mendorong dalam pembelian laptop merek Sony. Variabel iklan adalah variabel yang paling mendorong dalam pembelian laptop merek Toshiba. Variabel penghasilan orangtua paling mendorong dalam pembelian laptop merek Dell, variabel kepraktisan dan pengarh keluarga adalah variabel-variabel yang mendorong mahasiswa dalam pembelian laptop merek Axioo. Variabel pengaruh teman adalah variabel yang paling mendorong mahasiswa dalam pembelian laptop merek NEC dan yang terakhir adalah variabel pengaruh orangtua adalah variabel yang paling mendorong mahasiswa dalam pembelian laptop merek Dell.

Judul: Analisis perilaku konsumen dalam keputusan pembelian laptop merek Asus (Studi kasus mahasiswa S1 Institut Pertanian Bogor)
Abstrak: Business competition among manufacturers of laptop industry are very high to make Asus as a manufacturer and marketer of a fairly large laptop in Indonesia tried to maintain its market share, Asus should know in detail the behavior of consumers which will be the targeting of their products. Data processing is done by descriptive analysis, factor analysis, and analysis of Fishbein multiatribute. Based on the results of the study showed that the majority of respondents' characteristics-sex male, aged 21 years, and is undergoing classes in semester 7. The majority of respondents came from West Java, financial resources come from parents with average income of Rp. 500,001.00 - Rp. 1,000,000.00. Based on factor analysis, showed that the purchase of a laptop Asus affected by five major factors, there are seller influence factor , the factor of experience using different brands of laptops, feature factor, factor of status as a student, and a friend of factors influence. In the analysis of consumer attitudes, attributes are a major consideration in their buying decision is product quality, product benefits and features of products. Attributes which not considered to be most important is the color of the product. Consumer attitudes toward the attributes possessed Asus laptop can be good.

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
