Judul: Sistem manajemen perkebunan teh rakyat : studi kasus PT Teh Nusamba Indah, Kabupaten DT UII Sukabumi
Abstrak: Studi mengenai sistem manajemen perkebunan teh rakyat adalah menelaah manajemen pengorganisasian kegiatan produksi antara pabrik pengolah teh dengan usahatani teh. Penelaahan didasarkan kepada aspek-aspek manajemen pabrik Tehnusamba, manajemen usahatani teh dan manajemen hubungan fungsional antara Tehnusamba dengan petani teh. Tujuan studi sistem manajemen perkebunan teh rakyat adalah menelaah sistem. pengorganisasian kegiatan produksi teh rakyat yaitu PT Tehnusamba Indah dan usahatani teh rakyat khususnya ditinjau dari aspek perencanaan strategis. Penelaahan sistem manajemen perkebunan teh rakyat dilakukan dengan analisis SWOT yaitu menelaah kekuatan, kelemahan, kesempatan dan hambatan dari ketiga aspek manajemen yang terdapat di dalam sistem manajemen perkebunan teh rakyat. Dari hasil analisis dapat disimpulkan bahwa manajemen usahatani teh rakyat relatif baik, namun belum dapat memenuhi jumlah, mutu serta kontinuitas pemasokan pucuk sesuai harapan pabrik Tehnusamba. Hal ini disebabkan fungsi Unit Usaha Petani Teh dan Kelompok Tani belum dapat diandalkan sepenuhnya sebagai pembina dan usahatani teh anggotanya.

Judul: Pengkajian tentang Keadaan Produksi, Pengolahan dan Pemasaran dalam Perkebunan Teh Rakyat (Studi Kasus di Unit Pelaksana Proyek Teh Wanayasa Kabupaten Banjarnegara, Jawa Tengah)
Abstrak: Dengan diadakannya pengembangan teh rakyat di wilayah kerja UPP Teh Wanayasa sebagai usaha dalam meningkatkan pendapatan petani masih terus dihadapkan pada masalah produksi yang rendah per satuan luas dan harga yang rendah diterima petani. Produksi yang dicapai pada umur tanaman 3 - 10 tahun sebesar 0,2 - 1,2 ton per ha, sedangltan pada tanaman tua yang belum mengalami rehabilitasi, produksinya sebesar 0,2 - 0 , ston per ha. Dari hasil analisa usahatani diperoleh bahwa pendapatan perih tanaman tehitu sebesar Rp. 251 400,- per tahun. Dengan besar biaya per satuan produk Rp. 23,93 dan tingkat R/C Rationya sebesar 1,49 yang memberikan arti bahwa setiap rupiah biaya yang diperlukan dapat menghasilkan 1,49 rupiah penerimaan.

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
