Abstract Gempol Village is a village on Mount Ungaran that has made efforts to preserve orchid species. Through mentoring and training from the UNNES Research Team which began in 2011, as well as greenhouse facilitation from PT Indonesia Power, the Gempol village community who are members of the Omah Sawah Community began to make efforts to conserve orchid species. The results of the identification of the problems experienced by community groups as foster partners can be grouped into three aspects, namely knowledge and skills of acclimatization of orchids from plant tissue culture, post-acclimatization management/care, and supporting infrastructure for acclimatization of tissue cultured orchids, where these three aspects are interrelated. The methods used include lecture and question and answer activities, practice, and mentoring. The result achieved is that the orchid species acclimatization activity in Gempol Hamlet, Ngesrepbalong Village has been carried out with satisfactory results. Activities are carried out through training and assistance to community groups who are members of Omah Sawah. The results of the evaluation of the participants showed that the participants' understanding and skills improved after this activity was carried out, even providing ideas for participants to apply to cultivated orchids. The result is enough to generate economic income for the participants, because some of their cultivated orchids are sold.

Abstract

The Mx gene is a potential candidate as a genetic resistance marker to the avian influenza virus in chickens. The purpose of this study is to identify the potential of Mx gene as a marker of resistance to avian influenza viruses in various breeds of chicken. The study used an exploratory design using three common chicken breeds. The Kampong chicken, the Hy-Line Brown laying hen strain, and the White Leghorn broiler strain were collected from the local farms, and blood samples were drawn from each. The DNA of each sample was amplified by a pair of Mx gene primers (NE-F2/F and NE-R2/R). The polymerase chain reaction (PCR) product of Mx gene fragment was cut using restriction enzymes RsaI to determine the genotype of the Mx gene. The PCR-RFLP analysis in this study showed that 100% of the broilers were GG genotype. In laying hens, 80% were AG genotype, 10% GG genotype, and 10% of the sample was not successfully analyzed. In the Kampong chicken, 68.4% were GG genotype, and 31.6% were AG genotype. The results showed that DNA mutation identification can be applied to determine the genotype chicken against virus. The genotypes of Mx genes in chickens indicates avian influenza virus resistance; whereas, the chicken phenotype does not suggest their level of resistance.
