Abstract

Drosera capensis adalah spesies tumbuhan karnivora endemik wilayah Cape, Afrika Selatan yang dikenal memiliki bentuk dan fungsi fisiologis yang khas karena memiliki mekanisme active flypaper traps. Daun D. capensis memiliki tentakel yang dapat mengeluarkan cairan lengket untuk menangkap dan menyerap nutrisi dari mangsa yang diperoleh. Tujuan dari penelitian ini adalah untuk mengetahui keunikan D. capensis dalam memenuhi kebutuhan nutrisinya melalui berbagai interaksi dengan serangga. Metode yang digunakan pada penelitian ini berupa studi literatur (literature review) sistematis dari berbagai artikel dan buku berisi informasi yang menunjang. Koleksi sumber referensi dilakukan melalui berbagai basis data ilmiah seperti Researchgate, ScienceDirect, dan Google Scholar dengan kriteria inklusi dan eksklusi yang relevan. Berdasarkan hasil studi literatur menunjukkan bahwa fisiologi yang unik pada D. capensis yaitu dapat menarik mangsa secara visual (antosianin), extra-floral nectar (EFN), dan penciuman (volatil). Banyak serangga yang melakukan interaksi dengan tumbuhan ini khususnya kelompok Diptera dan Collembola yang menunjukkan adanya interaksi non-mutualistik. Mekanisme active flypaper traps pada D. capensis dilakukan melalui gerakan tigmonasti dengan menggulungkan daun untuk menangkap mangsa. Peristiwa ini dipicu oleh sinyal elektrik dan diikuti dengan aktivasi asam jasmonat yang terkait dengan produksi enzim pencernaan seperti protease. D. capensis juga memproduksi gland cell yang memiliki kandungan asam polisakarida yang membuat D. capensis memiliki lendir yang sangat lengket. Lendir tersebut berfungsi untuk menjerat dan menahan serangga, memfasilitasi transmisi sinyal elektrik, serta membantu dalam distribusi enzim pencernaan.

Abstract

The community in Suci Village, Panti Jember has recognized and cultivated family medicinal plants (TOGA) to provide traditional medicine because of its distance from the city center, limited health facilities and pharmacies. The utilization of TOGA is still limited as herbal medicine through liquid herbal medicine which is less practical and has a short shelf life, so it is necessary to carry out mentoring activities in the development of TOGA for herbal tea leaves. This activity aims to empower the community in Suci Village in optimizing the potential and utilization of local biodiversity as an ingredient for leaf herbal tea. The method of activity implementation included lectures, hands-on practice of making herbal tea leaves and discussions. The Biology lecturer team at the University of Jember introduced the local potential, health benefits of herbal tea leaves, and the production process from washing, drying, packaging, to marketing. The results of this activity showed that the socialization of the potential, benefits and production of herbal tea leaves increased community knowledge by 84% in the utilization of local plants for health and economic potential. In addition, interactive discussions generated additional ideas such as the utilization of beluntas leaves and coffee peels as herbal tea ingredients, as both ingredients are available in Suci Village and have not been optimally utilized. Through this activity, it is hoped that the community in Suci village will be able to develop herbal tea through the utilization of local potential that has health benefits and economic potential through environmentally friendly products.

Abstract

Heat Shock Protein 90 (HSP90) has an important role in regulating heat stress response, plant development control, and defense reactions. The HSP90 gene family has been extensively reported in numerous plant species, but studies on the HSP90 gene in cocoa (Theobroma cacao L.) remain lacking. Continuous global warming and the use of low-grade quality planting materials are the reasons for low cocoa productivity in Indonesia. Based on this, it is necessary to have good adaptability in cocoa as well as the development of new cultivars so that there is no decrease in cocoa productivity. This study aims to identify the HSP90 gene family in cocoa to recognize the HSP90 functioning in cocoa and provide the necessary information to characterize HSP90 at the genome level. Identification of the HSP90 gene family in T. cacao was carried out through analysis of TcHSP90 sequences obtained from various related databases. The results showed that a total of seven TsHSP90 genes are distributed into ten T. cacao chromosomes. Analysis of the TcHSP90 motif showed that HSP90 is conserved in each T. cacao gene. Cis-acting element analysis showed that TcHSP90 has important roles in growth and development as well as abiotic and hormonal stress responses including defense against pathogens. Phylogenetic analysis showed that TcHSP90 has a similar evolutionary distribution to A. thaliana and S. lycopersicum. The results of this study can be used as a scientific foundation and basic knowledge for the development of new T. cacao cultivars that are resistant to biotic and abiotic stresses by selecting suitable candidate genes for T. cacao breeding.
