Judul: Pengaruh Self-esteem dan Pencarian Informasi terhadap Perilaku Komplain dan Word of Mouth Konsumen Indonesia
Abstrak: Perilaku komplain dan Word of Mouth (WOM) adalah salah satu dimensi keberdayaan konsumen yang perlu ditingkatkan di Indonesia karena kondisi pasar global yang semakin kompleks. Penelitian ini bertujuan untuk menganalisis pengaruh self-esteem dan pencarian informasi terhadap perilaku komplain konsumen dan word of mouth konsumen di Indonesia. Data berasal dari penelitian berjudul "Pemetaan Indeks Pemberdayaan Konsumen (IKK) di Indonesia pada 2016-2017" dengan 2100 responden. Penelitian ini menggunakan teknik multistage random sampling secara sistematic random sampling. Analisis data menggunakan Structural Equation Modeling menggunakan LISREL 8.8. Temuan menunjukkan bahwa variabel pencarian informasi, perilaku komplain dan WOM masih relatif rendah, sedangkan self-esteem memiliki kategori sedang. Tidak ada perbedaan signifikan berdasarkan jenis kelamin dalam pencarian informasi dan perilaku komplain, namun terdapat perbedaan signifikan pada self-esteem dan WOM. Hasil juga mengonfirmasi bahwa self-esteem dan pencarian informasi memengaruhi perilaku komplain dan word of mouth.

Judul: Pengaruh Penanganan Komplain Terhadap Komunikasi Word-of-Mouth
Abstrak: Banyak konsumen yang mengalami masalah atau merasa tidak puas, masih tidak mau melakukan komplain salah satunya karena prosesnya membutuhkan waktu yang lama dan rumit, sehingga strategi penanganan komplain perlu diperhatikan oleh pelaku usaha untuk dapat mempertahankan eksistensi dan memperbaiki hubungan dengan konsumen. Penelitian ini bertujuan untuk mengetahui pengaruh penanganan komplain terhadap komunikasi Word-of-Mouth (WOM). Desain penelitian ini menggunakan studi kuantitatif dan cross-sectional dengan metode survey online yang dilakukan di Institut Pertanian Bogor. Responden dengan jumlah sebanyak 285 orang dipilih secara purposive, dengan syarat yaitu mahasiswa program sarjana Institut Pertanian Bogor yang sudah melewati tingkat pertama, pernah melakukan komplain, dan mendapat tanggapan dari pelaku usaha. Analisis data menggunakan metode SEM melalui program Analysis of Moment Structures (AMOS). Hasil penelitian adalah service recovery performance memengaruhi secara positif perceived justice dan kepuasan penanganan komplain, serta kepuasan penanganan komplain memengaruhi secara negatif komunikasi WOM.

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
