Judul: Pengaruh Literasi Keuangan dan Kelompok Acuan terhadap Perilaku Konsumtif Siswa SMA.
Abstrak: Perilaku konsumtif adalah perilaku membeli barang atau jasa secara berlebihan dan hanya mementingkan keinginan daripada kebutuhan tanpa didasari pertimbangan yang rasional. Penelitian ini bertujuan untuk menganalisis pengaruh literasi keuangan dan kelompok acuan terhadap perilaku konsumtif siswa SMA. Penelitian ini menggunakan desain cross sectional study dengan pemilihan lokasi penelitian secara purposive. Penelitian dilakukan dengan teknik self administered menggunakan kuesioner. Penelitian ini melibatkan 125 siswa SMA negeri Kota Bogor yang terdiri dari 68 siswa IPA dan 57 siswa IPS. Sekolah yang dipilih pada penelitian ini adalah SMA Negeri 3 Kota Bogor dan SMA Negeri 9 Kota Bogor. Alasan sekolah dipilih karena dekat dengan pusat perbelanjaan kota. Data yang didapat kemudian dianalisis menggunakan analisis deskriptif, uji beda, uji korelasi, serta uji regresi. Hasil penelitian menunjukkan terdapat perbedaan pada jenis kelamin terhadap perilaku konsumtif siswa SMA, perempuan lebih berpeluang berperilaku konsumtif. Hasil uji korelasi menunjukkan adanya hubungan antara karakteristik remaja, literasi keuangan, kelompok acuan dan perilaku konsumtif. Hasil uji regresi menemukan bahwa adanya pengaruh negatif signifikan perilaku keuangan terhadap perilaku konsumtif siswa SMA. Hasil penelitian juga menemukan adanya pengaruh positif signifikan jenis kelamin dan kelompok acuan terhadap perilaku konsumtif siswa SMA.

Judul: Pengaruh Interaksi Teman Sebaya dan Literasi Keuangan terhadap Perilaku Konsumtif Siswa Sekolah Menengah Pertama
Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh interaksi teman sebaya dan literasi keuangan terhadap perilaku konsumtif siswa Sekolah Menengah Pertama. Penelitian ini menggunakan desain cross sectional study dengan pemilihan lokasi penelitian secara purposive. Penelitian ini melibatkan 105 siswa yang bersekolah di salah satu sekolah negeri Kabupaten Bogor. Sekolah dipilih karena berada di lokasi yang dekat dengan pusat perbelanjaan yang diasumsikan dapat memengaruhi perilaku konsumtif siswa SMP. Data dikumpulkan melalui pengisian kuesioner kemudian dianalisis menggunakan analisis deskriptif, serta uji regresi. Hasil penelitian menunjukkan interaksi teman sebaya siswa termasuk pada kategori sedang, literasi keuangan tergolong kategori sufficient literate (cukup terliterasi), dan perilaku konsumtif siswa temasuk kategori sedang. Faktor yang memengaruhi perilaku konsumtif siswa SMP antara lain adalah usia siswa, pendidikan ibu, interaksi teman sebaya dan literasi keuangan. Usia siswa, pendidikan ibu, dan interaksi teman sebaya memiliki pengaruh positif signifikan terhadap perilaku konsumtif siswa, sedangkan literasi keuangan memiliki pengaruh negatif signifikan terhadap perilaku konsumtif siswa Sekolah Menengah Pertama.

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
