Antioksidan adalah suatu zat yang dapat menetralisir atau menyerap radikal bebas. Antioksidan berdasarkan sumbernya terbagi menjadi dua yaitu antioksidan alami dan antioksidan sintesis. Penelitian ini bertujuan untuk mengetahui aktivitas antioksidan pada kombinasi ekstrak etanol lidah buaya (Aloe vera L.) dan ganggang hijau (Ulva lactuca L.) dan nilai IC50 pada kombinasi ekstrak etanol lidah buaya (Aloe vera L.) dan ganggang hijau (Ulva lactuca L.)Jenis penelitian ini adalah eksperimental untuk mengetahui aktivitas antioksidan pada ekstrak tunggal dan kombinasi ekstrak lidah buaya (Aloe vera L.) dan ganggang hijau (Ulva lactuca L.) dengan perbandingan 1:1; 1:2 dan 2:1 dengan menggunakan metode DPPH. Hasil Pengujian aktivitas antioksidan d...

The research in this thesis uses a mixedmethod which is a mixed type of research, namely a combination of qualitative andquantitative which produces data in the form of words or sentences and also producesdata in the form of numbers or percentages of the observed subjects. The subjectsstudied were students of the Islamic Religious Education study program, Faculty ofTarbiyah and Teacher Training, IAIN Ambon, which consisted of 12 female students whostill wore the veil. Data collection methods used include interviews, questionnaires anddocumentation. Based on the results of the study found that: The motivation of studentsof the Islamic Education Study Program Faculty of Tarbiyah and Teacher Training IAINAmbon in using the veil is divided into two, namely intrinsic motivation which includes:mastery goals and need for achievement and extrinsic motivation which includes:...

Sunscreen is a cosmetic ingredient that functions as a physical or chemical function as a barrier to the penetration of UV rays into the skin. Plants that can function as sunscreens because they have phenolic compounds, one of which is green algae (Ulva lactuca L).This type of research is an experimental study using UV-Vis spectrophotometry to determine the ability of sun cream to inhibit UV radiation to the skin. The purpose of this study was to formulate sunscreen cream from ethanol extract of green algae (Ulva lactuca L.) and measure the best SPF (Sun Protecting Factor) value of various concentrations of green algae (Ulva lactuca L.) ethanol extract sunscreen cream.The results of the study the SPF value of formula 1 (cream base) was 1.5077, which means formula 1 has no activity as sunscreen, formula 2 (3% green algae extract) with formula 2 (3% extract extra...

Besides providing environmental-friendly process, green synthesis of nanoparticles using plant extract provides synergistic effect of the secondary metabolite in such antibiotic activity. The study with an intensification process in nanoparticles formation is also gaining great attention. This research deals with the green synthesis of silver nanoparticles using Datura metel flower extract for the antibacterial agent. The use of ultrasound-assisted method for the synthesis was investigated. Methods: Synthesis of silver nanoparticles (AgNPs) using Datura metel flower extract under ultrasound- assisted method has been conducted. Evaluation of the successful synthesis was done using UV-visible spectrophotometry, particle size analyzer, x-ray diffraction, and transmission electron microscopy. The prepared AgNPs were tested as an antibacterial against S. aureus, K. pneumoniae, S. pyogenes, and E. co...

The synthesized nanoparticles were detected by UV-Vis spectrophotometric analysis, x-ray diffraction, scanning electron microscope, and transmission electron microscope. The effect of ultrasound method on physicochemical properties of the nanoparticles was compared to the use of reflux method. The influence of the character on biological activity of the nanoparticles were tested for their antibacterial activity against Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus, and Streptococcus pyogenes bacteria. Chemical activity of the nanoparticles was also evaluated as antioxidant by using radical inhibition by using 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH) assay. The results showed that Clitoria ternatea flower exhibited reduction capability to form nanoparticles with the particle size ranging at 18-50 nm. In general, the ultrasound produces smaller particle size compared with reflux method for both silver and gold nanoparticles. The smaller particle size obtained from the ultrasoundassisted method compared to the Reflux method was found to give higher antibacterial activity toward tested bacteria. The nanoparticles demonstrated the antioxidative activity as shown by the DPPH inhibition at more than 50%. The results suggest that the use of Clitoria ternatea flower extracts as reducing agent and ultrasound-assisted synthesis are fit as a green method for the synthesis of silver and gold nanoparticles.

This research was conducted in SMA Negeri 5 Buru District Lilialy Kabupaten Buru, from September 1, 2020 to October 1, 2020. This research is a qualitative descriptive research with data collection techniques in the form of observations, interviews and documentation. The collected data is then analyzed qualitatively including: data collection, data reduction, data display and verification and affirmation of conclusions. The results showed that the use of multimedia can increase students' learning motivation in Islamic Religious Education subjects in the classroom X SMA Negeri 5 Buru, where students appear to focus on following the learning process, recording the subject matter, and are happy with the learning using multimedia, students easily explain or answer the teacher's questions PAI boldly and actively in the learning process. Supporting factors and inhibition factors of multimedia use in increasing students' learning motivation in Islamic Religious Education subjects in the Classroom X SMA Negeri 5 Buru among others, for supporting factors, namely the availability of leptop and computer, infokus, electricity, clean school walls, clean classrooms, and the ability of PAI teachers who are very good in integrating concepts with multimedia in the learning process as well as the availability of special classrooms designed for learning activities using multimedia infokus. As for the inhibition factor is infokus available only one, so it will be constrained when used by other teachers, then electricity is often out and internet access is often sluggish.
