Abstract

Background: Increased lipase activity can increase the amount of monoglycerides and fatty acids absorbed by the body, this is what affects obesity. If pancreatic lipase activity is inhibited, the production of fatty acids will decrease, consequently the level of fat in the blood will also decrease.Objective: To study anti obesity potential of a single herb or a mixture of green tea and other herbs (Syzygium polyanthum. Lv, Artocarpus communis.Lv, Cinnamomum verum..Lv, Manilkara zapota.Lv, Tectona grandis.Lv) by the in vitro inhibition assay of the lipase enzyme activityMethod: A single (8 herbs) or a mixture of three herbs powder (12 formulas) was put into a tea bag with a total weight of 1.5 g to be brewed in 100 mL bottled mineral water at 70⁰-90⁰C for 10 minutes. In vitro lipase enzyme inhibition assay were conducted to measure the ability of these samples as lipase inhibitor. Orlistat used as positive lipase inhibitor. Results: There was a difference results of lipase inhibition activity between the sample of a single and a mixture of herbs. Interestingly, the results shows that formula 3 (mixture of green tea, Manilkara zapota and cinnamon). has 53.942 % inhibition, formula 9 (a mixture of green tea, Syzygium polyanthum and cinnamon) has 67.322 % inhibition and formula 12 (a mixture of green tea, Tectona grandis and cinnamon) has 56.612 % inhibition which close to lipase inhibitory activity by standard Orlistat.Conclusion: The mixture of green tea and two other herbs has a lipase inhibitory activity similar to Orlistat, when compared to the single herb. The highest lipase inhibitory activity is found in formula 9.

Abstract

Lovastatin is an anti-cholesterol agent that was produced by Aspergillus terreus using solid state fermentation (SSF). During this fermentation process, sulochrin is also produced as an unwanted co-metabolite. However, our previous result showed that sulochrin had potential as antidiabetes because it is an inhibitor agent of α-glucosidase. In this paper, we reported our observation on lovastatin and sulochrin production pattern in relation with inhibitor α-glucosidase activity during eleven days fermentation of A. terreus koji (SSF) ethyl acetate extract. Koji obtained from solid state fermentation with rice as the substrate and incubated at room temperature, sample is taken daily for eleven day (D-1 to D-11). Lovastatin and sulochrin production was measured by Liquid Chromatography- Mass Spectrometer based on their molecular weight m/z 404.5 and 332.3 respectively. The inibitory activity is measured by inhibition model of koji extract against α-glucosidase (EC 3.2.1.20) from Saccharomyces cereviceae. The results show that lovastatin production was started on the day 2 (0.04 mg/g) and achieving the optimal production on day 7 (11.46 mg/g), while sulochrin production was started on day 4 (0.60 mg/g) and keep produced until the end of fermentation period at Day 11 (3.11 mg/g). Koji extract was started to show inhibitory to α-glucosidase activity on Day 5 (IC50= 23.34 μg/mL) and keep showed activity until Day 11 (IC50=3.33 μg/mL). These results suggest that inhibitory activity of koji extract to α- glucosidase activity have relation with sulochrin biosynthesis production.

Abstract

This research aims to analyze the sarcasm language style used in the 2024 presidential candidate debate, with a focus on the speeches and interactions between the candidates. This research uses a case study method with a close observation technique which involves the process of observing and recording information directly from the data source, namely the 2024 presidential candidate debate video obtained from the YouTube site @KPURepublikIndonesia to identify and classify the style of sarcasm used in the presidential candidate debate. The results of the analysis show that there is one style of propositional sarcasm, one style of illocutionary sarcasm, one style of prefix sarcasm, and one style of lexical sarcasm. With the presence of sarcasm in the 2024 presidential debate, the audience's perception and reaction to this strategy tends to be skeptical. The majority of respondents considered the use of sarcasm to be less important and had the potential to create a less constructive discussion atmosphere. Although a small number consider it important, most do not place much emphasis on the strategy.AbstrakPenelitian ini bertujuan untuk menganalisis gaya bahasa sarkasme yang digunakan dalam debat calon presiden (capres) tahun 2024, dengan fokus pada pidato dan interaksi antara kandidat.

Abstract

A This study discusses society's stereotypes about the ability of the blind.The stereotypes in question are general views and negative prejudices against the abilities and independence of the blind, so as to reduce their chances of being prioritized for facilities and not getting the opportunity to be empowered.The purpose of this study is to understand the factors that influence stereotypes about the ability of the blind and provide recommendations to reduce these stereotypes.The research method used is an online survey of respondents who are members of the general public from various backgrounds.The results of this study indicate that society's stereotypes regarding the ability of the blind are still very strong and are driven by internal and external factors of the blind themselves, such as social factors, lack of public knowledge about the ability of the blind, as well as self - faith that arises from the blind themselves.Not surprisingly, there are still many who think that blind people are less powerful when compared to sighted people.Therefore, efforts need to increase public awareness and knowledge about the abilities of the blind and eliminate existing stereotypes.
