Abstract

COVID-19 is a disease caused by viruses of the coronavirus class that are known to enter humans through the Angiotensin Coverting Enzyme (ACE II) receptor protein and transmembrane serine protease (TMPRSS 2). COVID-19 has become a pandemic, so it requires an agent that acts as an anti-Covid-19. Cananga odora is an herb that contains EO (Essential Oils) and is widely grown in Indonesia. EO are known to have antiviral potential.This study aims to explore the potential of EO from C.odora using a molecular docking approach by measuring its inhibition of ACE II (Q9BYF1) and TMPRSS2 (7MEQ). The inhibitory potential was calculated from the binding affinity using Pyrex Autodock Vina software. The docking results are then visualized using Biovia Discovery Studio and PyMOL. Prediction of physicochemical and pharmacokinetic profiles through pKCsm web. The docking results showed that geranyl acetate inhibited ACE II at Lys 562 with a gibs energy of -7.5 kcal. Thebest inhibition of TMPRSS2 by cedrole with energy gibs -6.2 kcal/mol via Pro 375. The active compound C. odorata has a different inhibitory mechanism from the control (chloroquine). The results of the in silico test predict the pharmacokinetic profile of EO from C.odora geranil asetat which has good absorption, distribution, metabolism and excretion values and is non-toxic, and cedrole can cross the blood brain barier.

Abstract

One of the causes of the failure of anemia prevention therapy in pregnant women with the potential for stunting is the side effects of nausea and vomiting from Blood Supplement Tablets so most pregnant women choose not to consume iron supplements given by the government for free. This has opened up opportunities for the discovery of product innovations for probiotic drinks from jalembi juice (red guava, lemon, melon, beetroot) with a starter Lactobacillus plantarum to be developed as a candidate for a health drink to replace anti-anemia anemia for pregnant women. The purpose of this study was to test the total lactic acid bacteria (LAB), pH, and temperature of jalembi juice probiotic drink with L. plantarum starter. This research method was carried out by calculating the total amount of LAB of L. plantarum using the Total Plate Count (TPC), pH, and temperature of the jalembi juice probiotic drink. Data analysis was carried out using a quantitative descriptive approach. The results of this study indicated that the total LAB of L. plantarum contained in the jalembi juice probiotic drink was 1.7 x 108 CFU/ml with an average pH and temperature of 3.38 and 22.4 ºC respectively. This study concludes that the total LAB in the jalembi juice probiotic drink with L.plantarum starter according to the recommended standards can have an effect on body health, which is around 108 -109 CFU/ml.

Abstract

Traditional knowledge seems to be the opposite of modern knowledge. In this position, the knowledge of the local community, especially in weaving works, is the result of processing the ancestral knowledge of the Sumba tribe in East Nusa Tenggara. This study aims to describe the potential of woven ikat not only as a work but also the culture of the people of Sumba as a teaching resource in schools. Ethnoscience is expected to become a bridge between science and culture approaches for students in the 21st century. This research is a type of ethnographic research with an interpretive design. Several methods, namely the in-depth interview method and the literature review method. In-depth interviews were used to explore the potential of Ikat weaving and literature analysis as secondary data in the study of student teaching materials. The study of Ikat weaving as a source of teaching materials includes aspects of coloring techniques, weaving techniques, and ethnomathematics of weaving motifs. The results of this study serve as reference material for learning in schools not only in local content subjects but can be integrated into the core content of Science/Science as well as Mathematics and other subject areas in formal schools.

Abstract

Poultry livestock are generally given feed in the form of corn kernels where the corn kernels contain high carbohydrates but have deficiencies of several amino acids. Amino acid deficiency can be overcome by increasing the protein content in the corn kernels. One way to increase the protein content in corn kernels is to carry out a fermentation process in corn flour solution. Therefore, this study aims to determine the effect of corn starch solution to increase dissolved protein levels in Saccharomyces cerevisiae biomass through a fermentation process. This study used a completely randomized design consisting of 8 treatments and 3 replications. The treatment volumes of corn flour solution were 0 mL, 5 mL, 10 mL, 15 mL, 20 mL, 25 mL, 30 mL and 35 mL. Data analysis used the calculation of variance and the BJND test. The results showed that the highest average dissolved protein content and total cell biomass of S. cerevisiae in the 15 ml treatment were 13.52%/g and 15.63 x 107 CFU/mL, the lowest average was in the 35 ml corn flour solution treatment, namely 0. 90%/gr and 3.01 x 107 CFU/mL. Based on the research, it can be concluded that corn flour solution can increase the dissolved protein content in S. cerevisiae biomass up to volume 15 mL/2 mL fermenter through the fermentation process. Based on the results of this study, it can be used as a basis for considering the use of S. cerevisiae fermenters to increase the nutritional value of corn seed-based animal feed.
