Effect of Acrylamide and Potassium Persulfate on The Characteristics of Water Hyacinth-Carrageenan Bead Gel Using Microwave Grafting Method
Get PDFThe cellulose of water hyacinth (Eichhornia crassipes) was utilized as raw material in bead gel production. In this research, hydrogel was prepared by grafting of acrylamide (AA) monomers onto the water hyacinth cellulose as the backbone using the microwave to produce hydrogel. This research aimed to determine the influence of adding AA and potassium persulfate (PPS) as an initiator on characteristic of swelling capacity in water. The cellulose powder obtained from the stem of water hyacinth was immersed in NaOH solution (1.5 N) for the delignification process for 10 min. The resulted cellulose was mixed with water and varying additions of 4, 7, dan 10 g acrylamide (AA) and 0.05, 0.10, and 0.15 g PPS to undergo grafting reaction. The obtained gel was washed and soaked in the acetone to remove the unreacted AA and PPS. The resulting precipitated solid was dried and called Water Hyacinth Cellulose Grafted Polyacrylamide (WH cellulose-g-PAA). The mixture of carrageenan with WH cellulose-g-PAA underwent crosslinking using aqueous KCl and CaCl2 after passing through palm oil layer to form bead gel. The properties of the dried bead gel were tested for functional groups using FTIR and for swelling capacity in water. Based on the FTIR test results, it can be concluded that AA monomers were successfully grafted onto the water hyacinth cellulose backbone. The addition of AA that is too low or too high will reduce the swelling capacity, as well as PPS

Did Trust in Government Induce the Impact of Loneliness and Self-Control on Student’s Compliance during Social Restriction Implementation? A moderator analysis
Get PDFThe mitigation strategy employed in addressing the prolonged pandemic situation in Indonesia yielded a discernment: collaborative efforts between individuals and the government were imperative to achieve the desired objectives. Despite the emergence of numerous psychological challenges among individuals during the pandemic, the pivotal role of public compliance became particularly evident during the implementation of social restrictions. Government initiatives to mitigate risks would not attain optimal effectiveness without substantial support from the public, either through trusting the government or adhering to regulatory measures. This study seeks to elucidate the moderating role of government trust in the impact of loneliness and self-control on students' compliance with social restriction policies during the Covid-19 pandemic. Conducted in early 2022 using a cross-sectional design, the study encompassed 401 undergraduate students from various regions in Indonesia. Employing Moderated Regression Analysis (MRA), the results demonstrated that trust in the government significantly moderated the effects of loneliness and self-control on student compliance (F(6, 403) = 101.017, p<0.001). The findings revealed that students were more inclined to comply with social restriction policies, even when experiencing loneliness, if they maintained trust in the government. This study underscores the significant role of government trust, particularly in situations necessitating cooperative behavior from the public in adhering to policies
