Judul: Pengaruh Dukungan Otonomi Orang Tua dan Kecerdasan Emosional terhadap Stres Akademik Siswa Madrasah Aliyah di Perdesaan dan Perkotaan.
Abstrak: Stres akademik merupakan perasaan negatif yang dirasakan oleh siswa yang berhubungan dengan akademik. Penelitian ini bertujuan menganalisis pengaruh dukungan otonomi orang tua dan kecerdasan emosional terhadap stres akademik siswa Madrasah Aliyah di perdesaan dan perkotaan. Contoh dalam penelitian ini melibatkan 180 siswa yang meliputi 86 siswa di perdesaan (Kecamatan Ciseeng dan Rumpin) dan 94 siswa di perkotaan (Kecamatan Bogor Barat dan Bogor Timur). Pemilihan sekolah dan contoh dalam penelitian ini dilakukan secara purposive. Data diperoleh dari self report dengan alat bantu kuesioner, data dianalisis menggunakan analisis deskriptif dan inferensia. Hasil penelitian menunjukkan bahwa stres akademik siswa di perkotaan lebih tinggi dibanding siswa di perdesaan. Secara umum jenis kelamin, lama pendidikan ibu, dan besar keluarga memiliki pengaruh signifikan terhadap stres akademik. Pengasuhan kontrol orang tua berpengaruh positif signifikan terhadap stres akademik, sedangkan dukungan otonomi dan kecerdasan emosional tidak berpengaruh signifikan terhadap stres akademik.

Judul: Pengaruh Keterlibatan Orang Tua dan Konsep Diri Akademik terhadap Stres Akademik Remaja di Wilayah Perdesaan dan Perkotaan
Abstrak: Individu yang memasuki masa remaja akan menghadapi tekanan akademik yang lebih besar dibandingkan dengan masa sebelumnya sehinggga dapat menyebabkan timbulnya stres. Stres yang disebabkan oleh tekanan akademik ini disebut stres akademik. Penelitian ini bertujuan untuk menganalisis pengaruh keterlibatan orang tua dan konsep diri akademik terhadap stres akademik remaja di wilayah perdesaan dan perkotaan. Penelitian ini melibatkan 227 siswa kelas 8 (109 perdesaan dan 118 perkotaan) dari SMPN 1 Rumpin, SMPN 1 Ciseeng, SMPN 4 Kota Bogor, dan SMPN 9 Kota Bogor. Pemilihan sekolah dan sampel dilakukan secara purposive. Data dikumpulkan dengan teknik self-report, lalu dianalisis menggunakan analisis deskriptif, uji beda, uji korelasi, dan uji regresi linier berganda. Hasil penelitian menunjukkan keterlibatan orang tua dan stres akademik remaja perkotaan lebih tinggi dibandingkan remaja perdesaan. Sementara itu, konsep diri akademik remaja perdesaan dan perkotaan tidak berbeda sgnifikan baik pada dimensi kepercayaan diri akademik maupun usaha akademik. Selain itu, hasil menunjukkan bahwa semakin tinggi konsep diri akademik dan semakin baik komunikasi orang tua-sekolah, keterlibatan di rumah, dan keterlibatan di sekolah maka semakin rendah stres akademik remaja. Selain itu, konsep diri yang tinggi akan menurunkan stres akademik remaja. Sementara itu, keterlibatan orang tua tidak berpengaruh signifikan terhadap stres akademik remaja di wilayah perdesaan dan perkotaan.

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
