Increase in Polyphenolic Substances from Fermented Robusta Coffee Pulp (Coffea canephora L.) by Using Indigenous Actinomycetes
No full textThe fermentation of the coffee fruit processing into coffee beans leaves the fermented coffee pulp which still contains polyphenol secondary metabolites. This study aimed to analyze the total flavonoid content (TFC) and total phenolic content (TPC) of fermented robusta coffee pulp (Coffea canephora L.) by using indigenous Actinomycetes. The ability of fermented extracts to inhibit free radical DPPH (2,2-diphenyl-1-picrylhydrazyl) also were done. In this study, coffee cherries were fermented in the solid-state fermentation cultivation (SSF) using isolates HJ4.5b, P2b(b).3 and P2b(b).18 which in previous studies were reported to have cellulolytic and xylanolytic activities. Determination of molecular identification base on 16S rRNA gen showed the isolates HJ4.5b and P2b(b).3 have similarities to the genus Streptomycetes, while P2b(b).18 has a homologous base arrangement with a rare actinomycetes genus Micromonospora. Fermentation using P2b(b).3 on the 9th day of fermentation indicated the highest percentage increase in TFC (295.54%) with IC50 18.41 µl/ml and having an antioxidant activity index (AAI) value of 2.14 which was included in the very strong antioxidant activity category

Research method of this research used qualitative content analysis. In this research, the data source includes scenes in the film The House That Jack Built 2018. Meanwhile, the data for this research are 40 image screenshots or visuals from the scenes presenting symbols. The data collection used in this research is a document study, this research is done by choosing the scenes identified as symbols and containing symbols. The data display of this research is presented in description. The theory used in this research is semiotic that focused on triadic semiotic proposed by Charles Sanders Pierce. The research findings show that conventional symbols and personal symbols are found in this film. Conventional symbols in this include colours, famous figures, nature, acts and expressions, places or settings, clothing, and the last is objects. while for personal symbols the author found including negative colours, an illustration of a human shadow, the smile corpse of a child named "Grumpy",the bodies in the cold storage room ,an old man named “Verge” wearing black clothes,Verge serving as Jack's guide , then finally pose like in the painting The Barque of Dante . These symbols are not just carelessly put into the film, but these symbols have meanings that are connected to the plot of the film, including symbols that symbolize the characters in the film. Because these symbols sometimes confuse the audience about their meaning, the writer does this research so that readers can understand the meaning of the symbols in the film.85 PagesSkripsi Sarjan

Congenital Malformations in Chicken Embryos After Oxybenzone Exposure
No full textTopical use of oxybenzone, commonly found in sunscreens, can be absorbed by the skin, and long-term use may cause endocrine disruption, cancer, and teratogenic effects. However, its potential teratogenic effects on embryonic development have not been well-studied. This study aims to determine the impact of oxybenzone exposure on the early stage of embryonic development. Chicken embryos aged 72 hours (20 Hamburger-Hamilton/HH stage) were exposed to a pure oxybenzone for 24 hours at varying concentrations (0, 1, 5, 10, and 20 ppm), each group consisting of 3 embryos. Embryo preparations were made using the wholemount method. Morphological abnormalities were observed with a stereo microscope, and descriptively morphometric measurements were analyzed using ImageJ software. Statistical analysis used One-way ANOVA and Tukey’s test for normally distributed data, while Kruskal-Wallis H and Mann-Whitney U test for non-normally distributed data. This study found that oxybenzone significantly enlarged the embryo, telencephalon, and eye. Several abnormalities were observed in the embryos exposed to oxybenzone, including incomplete closure of the anterior neuropore, concavity in the anterior and lateral of the mesencephalon, and depressions in the tail bud. This study concludes that oxybenzone acts as a teratogen, causing abnormalities in embryonic development, particularly in the central nervous system
Metagenomic Analysis of Bacterial Communities in the Musi River Estuary, South Sumatra, Indonesia
No full textUnderstanding the diversity, function, and ecological dynamics of bacterial communities depends on unique transitional environments, estuaries. Knowledge on bacterial taxa in the Musi River estuary, South Sumatra still eludes, however. This effort aims to identify bacterial species in estuary waters using metagenomic analysis based on 16S rRNA gene. Surface water samples from three study locations were analysed by DNA isolation, nanodrop spectrophotometer qualitative assessment, 16S rRNA gene amplification, electrophoresis, and Illumina NovaSeq sequencing. Results showed that Proteobacteria predominated at all sites, followed by Campilobacterota, Cyanobacteria, and Bacteroidota. At the class level, Gammaproteobacteria was most common, followed by Alphaproteobacteria and Campylobacteria. Dominant bacterial orders were Campylobacterales, Rhodobacterales, and Pseudomonadales while the most common families were Arcobacteraceae, Rhodobacteraceae, and Pseudomonadaceae. The most plentiful genera were Rheinheimera, Pseudomonas, and Pseudarcobacter. Variations in bacterial spread among stations suggest environmental factors including salinity, nutrient availability, and human activities influencing microbial community composition. Ternary plots, heat maps, and krona diagrams were employed to disclose distinct patterns of bacterial community dispersion in the estuary. This paper underscores the importance of metagenomic research in illuminating microbial diversity in estuarine environments and its impact on ecological dynamics and water quality
Perlindungan Hukum Terhadap Pembatalan Keberangkatan Konsumen Atas Pelayan dan Jasa Travel Umroh Dan Haji yang dfi Akibatkan Covid-19 (studi Kasus PT. Riau Bertuah Tour And Travel)
No full textThe presence of Covid-19 has had a major impact on paralyzing activities in various sectors. One of those affected was the religious sector, namely the cancellation of all Hajj and Umrah pilgrimage activities for the international community, especially Indonesia. This was reinforced by the issuance of a decision by the Minister of Religion of the Republic of Indonesia to cancel the 2020 Hajj pilgrimage. This cancellation is detrimental to pilgrims and service providers because their respective rights and obligations cannot be fulfilled, especially since Covid-19 is included in the force majeure category. The method used in this research is socio-empirical. Taking the object of study in terms of law which has empirical value, to answer questions that have been prepared by observation as done by the author, namely interviews with pilgrims and service providers. After the data has been obtained, it is grouped into primary data, secondary data, and tertiary data. Then the data is grouped according to the type of problem to be studied and the material obtained from the interviews will be presented by the author as a description for discussion. Based on the results of the study it can be concluded that pilgrims (consumers) do not get their rights fulfilled and service providers cannot fulfill their obligations due to the Covid-19 pandemic. However, service providers continue to be accountable to their consumers by defending their rights and acting in good faith so that consumers feel that their rights are still being protected
