Abstract

This study aims to examine the effectiveness of the addition of Silane Coupling Agent on physical properties (density, moisture content, thickness expansion, and water absorption) and flexural strength in the manufacture of areca nut peel fiber particle board with urea formaldehyde adhesive. The betel nut peel fiber was alkalized using NaOH for 2 hours, then mashed using a grinding machine until it passed a 50 mesh sieve. The betel nut skin fibers that have passed the sieve are then treated with a solution of Silane Coupling Agent. The concentration variations of the Silane Coupling Agent solution were 0%, 2%, 4%, 6% and 8%. The betel nut peel fiber that has been synthesized with a silane coupling agent solution is then mixed with urea formaldehyde resin in a ratio of 30/70 in weight percent. The particleboard compaction process uses a Hydraulic Cold Press compacting machine with a pressure of 5 bar and a holding time of 120 minutes. The results of this study indicate that the silane coupling agent treatment increases the bond between the matrix and filler as shown in the SEM test on particle boards with 8% silane coupling agent treatment. The results of the particleboard test on density, percentage of moisture content, percentage of thickness development have met the standard of SNI 03-2105-2006. The results of the water absorption test have met the ASTM D 570 standard. The results of the flexural strength test on the SCA 6% variation SNI 03-2105-2006 decorative particle board type 8 and the SCA 8% variation have met the SNI standard 03-2105-2006 structural particle board type 10.5.

Riau Province has reported 120 confirmed cases of COVID-19 and Pekanbaru City is the area with the most COVID-19 cases from 12 districts/cities. The World Health Organization (WHO) issued a decision so that people can practice social distancing which is very helpful in breaking the chain of COVID-19 transmission. However, some people in Indonesia still consider social distancing to be just an ordinary recommendation, resulting in the implementation of social distancing not being completely evenly distributed. The purpose of this study were to determine the relationship between knowledge and attitudes towards social distancing and the relationship between attitudes towards social distancing and social distancing behavior as an effort to prevent COVID-19 in young adults in Pekanbaru City in 2020. This study used an analytical observational study design with a cross sectional design. This research was conducted on a young adult population in Pekanbaru City in August 2020. The sampling technique used was cluster sampling with a sample of 120 respondents. Data retrieval on respondents was done by online method. Data analysis was carried out by means of the Spearman correlation test to obtain the p-value and correlation coefficient. The results of the Spearman's rho correlation analysis show that there is a significant relationship between knowledge and attitudes towards social distancing (p-value = 0.000) with a correlation coefficient of 0.899. In addition, there is a significant relationship between attitudes towards social distancing and social distancing behavior (p-value = 0.000) with a correlation coefficient value of 0.880. The conclusion of this study are that there is a significant relationship with a very strong correlation strength and a positive direction of correlation between knowledge and attitudes towards social distancing and there is a significant relationship between attitudes towards social distancing and social distancing behavior as an effort to prevent COVID-19 in young adults in Pekanbaru City in 2020.
