“…The finding confirms that the ease and convenience of using applications in learning is an essential component (Richardson et al, 2021;Teo & Noyes, 2014). Previous research stated that users believe that mobile phone applications are easy to use and understand and can use them skillfully; therefore, they want to adopt them (Chandrathilaka et al, 2021;Susanti et al, 2020). Other research also stated that the more comfortable users are in using an application, the more they are interested in using it (Hariyanti et al, 2020;Pratama et al, 2020).…”

In 21st century learning, the development of smartphone-based applications to support education, especially literacy, has become a basic need. This study aims to analyze the factors that factor in user acceptance of an Android-based application called Kumandang, Reading Aloud Activities. This type of research is survey research. The subjects of this study were ninety participants consisting of teachers, parents, and guardians. The research instrument used in this study was a questionnaire sheet. The technique of data collection is the distribution of questionnaires. The data analysis technique uses a structural equation model with the help of the SMARTPLS application. The study model uses UTAUT2, which consists of several indicators, including; Performance Expectations (PE), Business Expectations (EE), Social Influence (SI), Facilitation Conditions (FC), Price Value (PV), Hedonic Motivation (HM), and Habits of Behavioral Intentions (H). The results showed that business expectations (EE) related to the ease and convenience of using Kumandang positively affected user acceptance. In addition, hedonic motivation (HM) related to fun and entertainment also affects parents' intention to use the Kumandang application. The results also show that performance expectations (PE), social influences (SI), facilitating conditions (FC), habits (H), and price effects (PV) do not affect parents' acceptance of using the Kumandang application.

In this study, a hybrid manufacturing technique was proposed to fabricate composites of acrylonitrile butadiene styrene (ABS) with Bidirectional woven glass fiber mat (GF)/ABS and GF/Bidirectional woven carbon fiber mat (CF)/ABS. The composites were fabricated using fused deposition modeling 3D printing, followed by hot compression molding, and their flexural, impact, and dynamic mechanical behaviors were examined. Results indicated that composites with GF and ABS combinations had shown the highest maximum flexural strength (64.46 MPa) and impact strength (0.089 J/mm2). The hybrid composites showed intermediate performance between ABS and GF/ABS composites, with higher flexural strain before failure than ABS and GF/ABS. A comprehensive analysis utilizing scanning electron microscopy was carried out to evaluate the adhesion characteristics of the fiber‐matrix interface in impact‐tested samples. Dynamic mechanical analysis showed that GF/ABS composites had offered superior E′, E″, and tanδ than the hybrid configuration. The peak tan delta values obtained from ABS, GF/ABS, and GF/CF/ABS composites were utilized to determine their respective glass transition temperatures. The observed values for ABS, GF/ABS, and GF/CF/ABS composites were 109.65, 69.95, and 71.5°C, respectively. Some potential applications for the composites fabricated in this study could include the development of lightweight and strong components for aerospace or automotive industries.

Many teachers still experience problems in teaching early reading using the SAS method in the 21st Century. This problem is exacerbated by the sudden change in the teaching system due to the Covid19 Pandemic, which affects the implementation of boldly carried out learning. Therefore, this study aims to analyze whether teachers have applied the SAS method in early reading learning in the 21st Century during bold learning or not. This type of research is survey research with a quantitative descriptive approach. The number of samples was 64 parents of students who were randomly selected using the probability sampling technique of simple random sampling type. Sampling in the study was calculated using the minimum sample table according to Krejcie and Morgan. The instruments used include questionnaires, observations, and interviews. The research data shows an increase in each initial learning meeting using the SAS method in the 21st Century during bold learning. It is proven by the results obtained in the first meeting, which were very good, the second meeting was very good, the meeting was very good, and the meeting was very good. In addition, the data on the spread of distribution shows that all parents say that the average tendency of teachers to apply the SAS method in the 21st Century in learning is in the good brave category.
