Abstract

Vetiver grass (Chrysopogon zizanioides, Poaceae) is the leading commodity in Garut Regency, Indonesia, the second-largest producer in the world of vetiver oils. The content of vetiver oils is strongly influenced by the environment, for example, drought stress. Drought stress causes plants to adapt by producing secondary metabolites such as essential oils. This experiment aimed to analyze growth, phytocomponents and obtaining the best quality of vetiver grass accessions under drought stress. The results showed that root and shoot dry biomass were significantly affected by the interaction between drought stress duration and vetiver grass accession. The root dry biomass of Kamojang accession decreased by 25.4%, while Cilawu increased by 5% for 4 days of drought stress. The root length and shoot length were not significantly affected by the treatment. The highest root/shoot length ratio was Verina, and the lowest one was Cisarua. The highest increase in proline occurred in Cilawu accession (85.7%), while the lowest was Verina (6.67%). Essential root oils contain 53 types of phytocomponents, dominated by sesquiterpenes, being khusimol, the highest type. The Cilawu is the best accession based on growth and content rendement.

Abstract

Cyprinus carpio is an economically crucial freshwater commodity in Indonesia and across the globe. Fish demand has a rising trend, which not in line with productivity. Innovation and aspects of food safety are the primary keys to increasing productive capacity. Therefore, the utilization of Manihot utilissima leaves as an alternative to improve national fish's productivity rate is a worthy consideration. They have multiple nutrients, including protein and fat needed by C. carpio seeds. This study aims to determine the optimal dose of M. utilissima supplementation to increase the productivity of C. carpio seeds. The methodology consisted of four treatments (0.5 mL/250 g, 10 mL/250 g, 15 mL/250 g) with four replications for 21 days. The outcome showed that P4 treatment (15 mL) could increase the relative growth rate by 21.10%/day, and it decreased the feed conversion ratio by 0.84. However, there is no significant effect on the survival rate. The study concludes that P4 treatment (15 mL) has positively increased the relative growth rate of C. carpio, and decreased its feed conversion ratio.

Abstract

The true frog species, Odorrana hosii, found in West Sumatera Indonesia, has high morphological differentiation and also estimated has high genetic variation. A total of 35 O. hosii at a seven location have analyzed using DNA microsatellite markers. Genetic variation of five microsatellite loci provided the highest value of expected heterozygosity (He) for the population in Padang (He= 0.618), while the lowest was the population in Merapi (He= 0.427). There are genetic differences in moderate levels among populations of O. hosii in West Sumatra (FST= 0.108) with inbreeding intrapopulation value (FIS= -0.559), and high value of gene flow among the populations (Nm = 2.061). This study becomes the first molecular data for establishing effective population management conservation.

Abstract

Eucalyptus urophylla is one of the typical plants of the Province of East Nusa Tenggara,  Indonesia whose distribution includes the islands of Timor, Alor, Wetor, Flores, Adonara, Lomblen, and Pantar. The best land for the growth of E. urophylla is an area with rainfall above 1000 mm every year. E. urophylla dominate the island of Timor hence the potential to absorb carbon and store it in biomass as part of climate change mitigation. This study aims to determine the allometric equation model to predict the potential of E. urophylla stem biomass. Calculation of the amount of stem biomass based on allometric equations is an analytical method used in this study. The sample trees used in equation modeling is 100 trees as a result of the inventory. The equations that can be used to estimate the biomass potential of the stem of  E. urophylla in Timor Island were ln  = -2.12 + 2.472 ln ( ) and (R2= 0.98); ln  = -3.617 + 1.046 ln  and (R2= 0.99); and ln  = -3.510 + 2.157 ln ( ) + 0.983 ln  and (R2= 0.99). The stem biomass potential with the model I amounting to 276.877 tons ha-1, model II of 279.671 tons ha-1, and model III of 280.209 tons ha-1.

Abstract

The new coronavirus (SARS-CoV-2), which caused the global pandemic Coronavirus Disease-2019 (COVID-2019), has infected nearly 206 countries. There is still little information about molecular compounds that can inhibit the development of infections caused by this disease. It is crucial to discover competent natural inhibitor candidates, such as antiviral peptides, because they have a variety of biological activities and have evolved to target biochemical machinery from different pathogens or host cell structures. In silico studies will be carried out, including protein-peptide docking and protein-protein docking, to identify, evaluate, and explore the affinity and molecular interactions of the Magainin-1 and Magainin-2 peptide molecules derived from frog skin (Xenopus laevis) to the main protease macromolecule (Mpro) SARS-CoV-2, and its effect on the ACE-2 receptor (Angiotensin Converting Enzyme-2 Receptor). Protein-peptide docking simulations show that both peptide molecules have a good affinity for the active site area of the SARS-CoV-2 Mpro macromolecule. These results were then confirmed using protein-protein docking simulations to observe the ability of the peptide molecule in preventing attachment to the ACE-2 receptor surface area. In silico studies show that Magainin-2 has the best affinity, with a bond free energy value of −3054.53 kJ/mol. Then the protein-protein docking simulation provided by Magainin-2 prevented the attachment of ACE-2 receptors, with an ACE score of 1697.99 kJ/mol. Thus, through in silico research, the Magainin peptide molecule can be further investigated in the development of new antiviral peptides for the treatment of infectious diseases of COVID-19.
