Abstract

Silver nanoparticles have been studied for its application in wound healing therapy, while aqueous extract of Plantago major L has been studied also for its antibacterial and wound healing activity. This study aimed to obtain silver nanoparticles (AgNPs) through a green synthesis pathway using aqueous extract of Plantago major L. The initial study was performed to optimize the three concentration points of Plantago major L. aqueous extract, namely 0.125%, 0.25% and 0.5% and three synthetic temperature points (60 °C, 70 °C, and 80 °C). The formation of AgNPs were confirmed using a UV-Vis spectrophotometer which shows a peak at a wavelength of 445 nm. The obtained silver nanoparticles were then characterized using Dynamic Light Scattering (DLS Nano), Scanning Electron Microscope (SEM) dan X-Ray Diffraction (XRD). The study showed that the extract concentration of 0.25% with an optimum temperature of 70 °C was the optimal combination to produce the best AgNPs, based on the organoleptic parameters (as the color of silver was produced), the highest yield with weight of 9.13 mg and particle size of 129.20 nm with Polydispersity Index (PDI) of 0.25. The morphology of AgNPs showed the spherical shape and the crystallization of AgNPs showed a diffractogram pattern similar to the silver standard using X-Ray Diffraction (XRD). Antibacterial activity of AgNPs was tested against three bacterial strains, namely Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa and was measured with diffusion method using paper disc. The antibacterial activity testing showed that AgNPS has better antibacterial activity than silver nitrate and is equivalent to its comparative antibiotics, gentamicin sulfate for gram-negative bacteria and Chloramphenicol for gram-positive bacteria.

Abstract

Skripsi ini membahas tentang konflik dalam novel “fadaytuki yā layla”karya Yūsūf al-Sibā‘ī.Penelitian ini bertujuan mengidentifikasi konflik yang terdapat pada novel, serta menganalisis penyebab terjadinya konflik dan konflik yang menyebabkan klimaks. Jenis penelitian yang digunakan adalah penelitian pustaka.Metode pengumpulan data menggunakan metode penelitian kepustakaan, melalui teknik catat secara cermat, sedangkan metode analisis data dengan menggunakan metode analisis deskriptif yaitu memberikan gambaran yang jelas tentang permasalahan yang sesuai data yang ada. Berdasarkan penelitain yang dilakukan, ditemukan konflik internal dan eksternal.Adapun konflik internal berwujud rasa khawatir, pertentangan ide dan kekecewaan.Konflik eksternal terdiri atas konflik fisik dan konflik sosial.Konflik fisik berwujud kematian mendiang Layla yang meninggal karena jatuh dari kincir angin.Adapun konflik sosial berwujud kekesalan, ketakutan, heran dan keterpaksaan.Penyebab konflik pada novel ini terbagi pada dua bagian konflik iternal dan eksternal, penyebab konflik internal adalah pertentangan diri kejiwaan.Adapun penyebab konflik eksternal adalah memaksakan kehendak dan perbedaan keinginan.Sedangkan konflik yang menyebabkan terjadinya klimaks dalam novel “fadaytuki yā layla”karya Yūsūf al-Sibā‘īberwujud karena Ibrahim memiliki rasa bersalah yang tinggi atas kematian adiknya yaitu Layla kecil dan Ibrahim tidak dapat menjelaskan perasaannya kepadaLayla yang membuatnya meninggal dunia.

Abstract

This article employs a literature review research method to comprehend and explore theories from various sources related to the research. The literature review is conducted through four stages, namely preparing the necessary tools, compiling a working bibliography, organizing time and readings, and recording research materials. In data collection, a search and collection method is utilized, sourcing information from various outlets such as books, journals, and previous research. Literature is critically analyzed to support recommendations and ideas. The results and discussion highlight the philosophy of communication, ontology, epistemology, axiology, and logic within the context of communication science. Focusing on the philosophy of science, ontology describes the nature of communication, epistemology discusses ways of acquiring knowledge, axiology examines the benefits of scientific knowledge and ethical values, while logic emphasizes principles of correct thinking and reasoning. The article also discusses communication phenomena, self-concept, and the functions of human communication, relating them to the evolving paradigms and theories in the realm of knowledge.

Abstract

The use of social reality construction theory as an addition to social exchange theory is a significant step towards understanding more deeply the impact of social media on interpersonal communication. Social reality construction theory offers a powerful perspective on how social media can shape individuals' perceptions of the reality around them. In this research, the literature method is used with a focus on reviewing and analyzing literature related to the impact of social media on interpersonal communication. The research aims to conduct a critical review of interpersonal communication theory and analyze how this theory has implications for social relationships in the digital era. This research shows that overall, changes in patterns of social relations that arise as a result of social media can be understood through the lens of social exchange theory. Social media provides a platform for information exchange, support, and social interaction, however, the impact is the emergence of dynamics that can sometimes sacrifice the depth and quality of traditional interpersonal relationships.

Abstract

The involvement of women in the productive business sector will lead to social change. The entry of women into the labor market or productive work affects household economic activities, resulting in changes in the family's economic structure. This became the rationale for this PKM activity to be carried out. The partners for this activity were a group of housewives in RT 65, Karang Anyar sub-district and Beringin Area, which became the basis for the premise that it was very necessary for this group of housewives to be provided with entrepreneurial skills and product-making skills that could be developed to improve the family economy. The problems of this group of housewives include: there is no guidance in increasing the empowerment of housewives, community activities have not been directed at increasing the knowledge and skills of housewives in terms of their contribution to improving family welfare, community activities that have narrowed into productive economic activities have not been implemented, Entrepreneurial activities for housewives are very limited and have not been developed and there is no stimulant assistance in the form of training and tools that are in accordance with their interests and skills as an incentive to apply their potential. The solution taken is training in product manufacturing skills and an understanding of entrepreneurship.
