Abstract

Mangroves plants such as Rhizophora apiculata are known to possess a diverse array of bioactive compounds with antioxidant and photoprotective properties. This study aimed to evaluate the anti-UV activity and bioactive composition of the ethyl acetate extract of R. apiculata leaves. The extraction was performed using the maceration method over 3 24 hours with ethyl acetate as the solvent. UV absorption was assessed using UV-Visible spectrophotometry, while compound identification was carried out through Gas ChromatographyMass Spectrometry (GC-MS). The extract exhibited significant UV absorption in the 290320 nm range, with Sun Protection Factor (SPF) values ranging from 2.5300.03 (low protection) to 37.0800.47 (high protection), indicating strong potential as a natural sunscreen agent. GC-MS analysis revealed several bioactive constituents, including lupeol, friedelan-3-one, cyclohexane-1,3,5-triphenyl, -tocopherol, and 1,3,5,7-cyclooctatetraenecompounds recognized for their UV-absorbing and antioxidant activities. The synergistic action of these phytochemicals is believed to contribute to the extracts overall photoprotective efficacy.Keywords:Rhizophora apiculataBioactive compoundsAnti-UVExtractEthyl Acetate

Abstract

This Study Aims To Obtain The Information And Data Of The Implementation Of Academic In Improving Teacher Competences. The Method Used In This Research Is Descriptive Method With Qualitative Analysis Approach. The Results Showed That: (1) The Education Office And The Supervisors Involved In The Preparation Of Academic Supervision Program By Analyzing The Earlier Programs. The Main Objective Of Academic Supervision Activities Is To Develop Teacher Capacity In Learning Aspects; (2) The Supervision Techniques Include Class Visit, Group Discussion, And Individual Discussion; All Of Which Are Still General; (3) Supporting Factors Include Motivating Teachers To Uphold The Urge And Willingness To Teach And Equipping Them With Various Teaching Methods. The Inhibiting Factors Include The Lack Of Time Allocation For Academic Supervision. A Supervisor Handles Up To 10 Schools. Thus, Not All Teachers Get Utmost Supervision.

Abstract

Expression speech acts are a form of a person's natural expression of what is actually felt. The speech acts of expression of Aceh tsunami survivors provide important information about how the survivors perceived the 2004 tsunami event. Expressing what they thought, believed and felt when they experienced the tsunami. Was the tsunami the apocalypse or a warning from God? One form of speech act of expression is self-centered speech act of expression, which is the speech act of expression of survivors to themselves. How are the forms and functions of self-centered expressive speech acts produced by Aceh tsunami survivors. A qualitative research method with a pragmatic approach is used to examine the data sources, namely 105 manuscripts of the experience stories of the survivors of the 2004 Aceh tsunami collected in a book entitled Tsunami and Their Stories by the Provincial Archives of Nanggroe Aceh Darussalam. The data in this study are excerpts of speech acts of expression of the Aceh tsunami survivors. The data were collected through documentation study, namely reading carefully, identifying, marking, and sorting the data into specific topics. Data analysis was conducted using a qualitative data analysis model, namely reducing data, presenting data, and drawing conclusions. The results showed that the survivors of the 2004 Aceh tsunami expressed 11 forms of self-centered expressive speech acts. The survivors expressed their emotions in accordance with social, cultural, and religious norms. In the context of a religious Acehnese society, the various speech acts of the survivors' expressions reflected a strong faith and acceptance of the disaster as part of God's will. Islam and Acehnese culture build the construction of speech acts of expression centered on the survivors of the 2004 Aceh tsunami. Keywords: self-centered speech acts of expression, Aceh tsunami survivors, Islamic values and Acehnese culture

Abstract

Sea cucumbers are a type of marine organism with significant economic worth and potential applications as nutraceuticals. This marine organism possesses possibly useful chemicals, making it a viable alternative for the fisheries product processing businesses. The objective of this study was to assess the efficacy of the methanol extract of Holothuria atra in preventing the formation of calculi and its ability to inhibit the growth of bacteria. Extraction was performed using the maceration method with methanol as the solvent over a period of 72 hours The analysis revealed the presence of four bioactive components in the methanol fraction: alkaloid, triterpenoids, flavonoids, and saponins. In vitro anticalculi activity was assessed by measuring the decomposition of kidney stones (Ca) using an atomic absorption spectrophotometer (AAS). The maximum decline of calcium stones was regarded at a concentration of 500 ppm of sea cucumber extract. The disc diffusion method was employed to assess the antibacterial activity against Escherichia coli and Staphylococcus aureus. The inhibition zone diameter was measured at all concentrations (25%, 50%, 75%, and 100%), indicating their potential as antibacterial agents. The greatest level of antibacterial effectiveness against Escherichia coli was observed at a concentration of 50%, resulting in a zone of inhibition of 1.90 mm. In contrast, the most significant antibacterial activity against Staphylococcus aureus was observed at a concentration of 25%, resulting in a zone of inhibition measuring 4.50 mm.Keywords:Holothuria atraExtractMethanolAnticalculiAntibacteria

Abstract

Sea cucumber (Holothuria atra) was used as a reducing and capping agent in the green synthesis process to produce silver nanoparticles (AgNPs). The antioxidant activity of the generated silver nanoparticles was then evaluated. Seacucumber extract was mixed with the AgNO3 solution and homogenized using a magnetic stirrer to create the silver nanoparticles. It was determined that silver nanoparticle production had occurred using a UV-Vis spectrophotometer. Before being examined for antioxidant activity, the generated nanoparticles were first given a characterizing using Fourier Transform Infra Red (FTIR) spectrometers. The maximum uptake was obtained at wavelengths of 440 cm-1 using a UV-Vis spectrophotometer. Functional groups that play a role in the synthesis of nanoparticles were -OH- C=O, and C-O groups. The free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) with an absorbance maximum (517 nm) was used for antioxidant properties. The antioxidant assay showed that Silver nanoparticles had higher antioxidant activity than sea cucumber extract alone, with an IC50 value of 4 ppm.Keywords:AntioxidantSeacucumberGreen SynthesisSilver NanoparticlesDPPH
