Abstract

Polystyrene (PS) is commonly employed in insulation, packaging, filters, and medical equipment, with recent studies exploring its potential in fiber membrane production. The electrospinning technique is discussed to synthesize PS fiber membranes with high porosity and controllable diameter. Additionally, incorporating silver nitrate into PS composite fibers is explored for enhanced functionalities such as catalytic activity, high electrical conductivity, and antibacterial activity. However, PS composite fiber membranes with silver nitrate (AgNO3) metal variations are rarely observed. This research aims to modify the microstructure of PS fiber membranes produced using electrospinning by adding silver nitrate (AgNO3) with varying concentrations. PS-Ag fiber membranes are produced using N,N-dimethylformamide (DMF) solvent, which serves as a solvent and a reducing agent for Ag. The results show that the effect of Ag affected the diameter of the PS-Ag fiber membrane, with an average diameter of around 3.67 - 6.93 micrometers. Degradation occurred in these samples at a strong broadening peak near ~1300 cm-1 until ~1600 cm-1 from the Raman results. The FTIR results show that the wavelength of ~3500 cm-1 indicated the presence of OH. The presence of OH indicates that the PS-Ag fiber membrane has the potential for water filtration application

Abstract

Penelitian ini bertujuan untuk menginvestigasi kontribusi rasa syukur (gratitude) dan dukungan sosial terhadap kesejahteraan psikologis ibu bekerja di Indonesia. Penelitian ini menggunakan pendekatan kuantitatif dengan melibatkan 106 ibu bekerja di Indonesia berusia antara 20 hingga 60 tahun. Data dikumpulkan melalui kuesioner daring yang terdiri atas Gratitude Questionnaire–Six Item Form (GQ-6), Multidimensional Scale of Perceived Social Support (MSPSS), dan Ryff’s Psychological Well-Being Scale (versi singkat). Analisis data dilakukan dengan teknik regresi untuk menguji pengaruh antar variabel. Hasil analisis regresi berganda menunjukkan bahwa rasa syukur dan dukungan sosial secara bersama-sama menjelaskan 27,1% variasi kesejahteraan psikologis (R² = 0,271; F = 19,099; p < 0,001). Temuan ini mengindikasikan bahwa model yang digunakan signifikan secara statistik, meskipun sebagian besar variasi kesejahteraan psikologis dijelaskan oleh faktor lain di luar lingkup penelitian ini. Temuan penelitian ini dapat memberikan masukan praktis bagi ibu bekerja untuk meningkatkan rasa syukur, serta bagi pihak-pihak yang terlibat dalam memberikan dukungan kepada ibu bekerja bahwa dukungan tersebut dapat berkontribusi pada peningkatan kesejahteraan psikologis mereka.
