Abstract

Lampung Indonesia is one of the provinces on the island of Sumatra, which has a flora conservation area located in Liwa Botanical Garden, West Lampung Regency. One of the flora species in the area with a high level of diversity is the orchid plant. The Dendrobium is the largest orchid species, where the public widely hunts this orchid for an economic reason due to the beauty of its various flower shapes and colors. Given the high level of human encroachment, this can threaten the existence of natural orchid plants, causing loss of their original habitat and causing the extinction of orchid species. Based on data in Liwa Botanical Garden, there has been no further identification of natural orchids as a plant conservation effort. To protect and immediately save these natural orchids, it is necessary to identify the Dendrobium orchid species based on the leaf morphological approach. This research will be conducted in April-September 2020. Observations of leaf morphology include leaf shape, leaf tip shape, leaf base shape, leaf edge, leaf reinforcement, leaf arrangement, leaf surface texture, leaf symmetry, and leaf sitting based on guidelines for ornamental plant characterization books. Observations as secondary data were added to the character of the pseudobulb shape and orchid habitat. Observations as secondary data were added on the habitat character of pseudobulbs and orchids. The implementation of this activity is still in the period of the Covid-19 pandemic, so most of the activities are carried out online. The coaching and training phase was conducted through internal virtual discussions on Tuesday, July 7, 2020, while the coaching phase was conducted through meetings or verbal communication via telephone groups and WhatsApp. Based on the evaluation data, it is known that there is an increase in knowledge and understanding of training participants by 21.64 points. The percentage increase in value before and after training is 34.72%. Orchid-related activities at Liwa Botanical Garden were never carried out, thus imparting knowledge to Liwa Botanical Garden technicians and workers on the development of natural orchid identification methods based on the morphological character in local natural resource conservation in the 4.0 industrial revolution era.

Abstract

Phylogenetics is known as a study related to biological science. Phylogenetics provides facilities in the fields of human epidemiology, ecology, and evolutionary biology. In evolutionary science, this field of science is used to integrate spatial data in detecting the journey of living things over time. In health biology, the development of this science is also used to detect the spread of disease/pathogens from a region to the global direction. Phylogenetic analysis is able to describe the origin of the disease, the pattern of distribution, and speciation. In the pandemic analysis, several diseases that have been analyzed are the Chikungunya virus outbreak in 2007, Ebola and H3N2 influenza virus in 2014, and the SARS-CoV-2 virus in 2020. The study results reveal that the SARS-CoV-2 virus has three variants of lineage groups, namely types A, B, and C. The Covid-19 virus type A was first discovered in Wuhan City, China. Meanwhile, the type A virus mutation is seen in the United States and most of these viruses have also been found in corona positive patients from Australia. The Covid-19 type B virus was detected in patients living in East Asia, while the Covid-19 type was concentrated in the European region.

Abstract

Anggrek (Orchidaceae) merupakan salah satu tanaman hias yang digemari karena bentuk dan warna bunganya yang bervariasi serta dapat digunakan sebagai bunga potong, tanaman pot, atau elemen taman. Penyakit infeksi masih menjadi kendala utama dalam budidaya tanaman anggrek di Indonesia. Odontoglossum ringspot virus (ORSV) merupakan salah satu jenis virus yang paling banyak dilaporkan menginfeksi tanaman anggrek dan tersebar luas di dunia, termasuk di Indonesia. Infeksi menyebabkan perubahan warna dan bentuk daun serta bunga. Penelitian ini dilakukan dengan menginjeksi virus secara mekanis pada anggrek Phalaenopsis amabilis atau Dendrobium Salaya Fancy. Penelitian ini bertujuan untuk mengetahui gejala dan terjadinya penyakit, serta ketahanan anggrek terhadap ORSV. Hasil penelitian menunjukkan bahwa setiap anggrek memiliki gejala penyakit yang parah, tingkat keparahan penyakit pada kedua tanaman anggrek sekitar 80% serta reaksi Phalaenopsis amabilis sangat rentan dan respon Dendrobium Salaya Fancy toleran terhadap ORSV. Hal ini membuktikan bahwa Phalaenopsis merupakan jenis virus anggrek yang paling mudah terinfeksi dibandingkan Dendrobium.

Abstract

Orchid is one of the popular ornamental plants that widely grown in Indonesia. However, the process of orchid cultivation is often hampered by virus infections. The virus that often infects the orchids is Odontoglossum ringspot virus. Viruses that enter orchid cells and replicate will activate the orchid’s defense response. This defense response is characterized by the increase of peroxidase activity. The peroxidase enzyme works in the formation of lignin to thicken cell walls and prevent viruses from entering other cells. In addition, the orchid defense response can also be activated through induced systemic resistance by inoculation of Ceratorhiza sp. as endophytic mycorrhizae. In this study, Factorial Complete Randomized Design (CRD) was used with 2 factors. Factor 1 is the type of orchid (Phalaenopsis amabilis and Dendrobium discolor) and factor 2 is the type of treatment (inoculation of mycorrhizae, virus, and mycorrhizae-virus). The orchid’s resistance level is determined by the analysis results of peroxidase activity using spectrophotometer. The results obtained indicate that all treatment combinations strongly influence the increase of peroxidase activity. Peroxidase activity of Phalaenopsis amabilis is 1.42 [(Umg) / min] and Dendrobium discolor is 1.64 [(Umg) / min] in average. Peroxidase activity on Dendrobium discolor was higher than on Phalaenopsis amabilis. This indicates that Dendrobium discolor has a higher level of resistance when compared to Phalaenopsis amabilis.Proses budidaya anggrek seringkali terkendala oleh infeksi virus. Adapun virus yang paling banyak menginfeksi anggrek adalah ORSV. Virus yang masuk ke dalam sel anggrek dan bereplikasi akan mengaktifkan respon pertahanan anggrek. Respon pertahanan ini ditandai dengan peningkatan aktivitas peroksidase. Respon pertahanan anggrek juga dapat diaktifkan melalui induksi resistensi sistemik dengan inokulasi Ceratorhiza sp. sebagai mikoriza endofit. Dalam penelitian ini digunakan Rancangan Acak Lengkap (RAL) Faktorial dengan 2 faktor. Faktor pertama adalah jenis anggrek (Phalaenopsis amabilis dan Dendrobium discolor) dan faktor kedua adalah jenis perlakuan (inokulasi mikoriza, virus, dan mikoriza virus). Tingkat ketahanan anggrek ditentukan dari hasil analisis aktivitas peroksidase menggunakan spektrofotometer. Hasil yang diperoleh menunjukkan bahwa semua kombinasi perlakuan sangat berpengaruh terhadap peningkatan aktivitas peroksidase. Aktivitas peroksidase Phalaenopsis amabilis rata-rata 1,42 [(U/mg)/ menit] dan Dendrobium discolor 1,64 [(U/mg)/ menit]. Aktivitas peroksidase pada Dendrobium discolor lebih tinggi dibandingkan dengan Phalaenopsis amabilis. Hal ini menunjukkan bahwa Dendrobium discolor memiliki tingkat ketahanan yang lebih tinggi jika dibandingkan dengan Phalaenopsis amabilis.
