Unsaturated polyester (UP) resin containing aromatic ring was blended with vinyl ester (VE) at wide range composition (10, 20, 30, 40,and 80 wt.%) using mechanical blending method. The blends were cured at room temperature using methyl ethyl ketone peroxide (MEKP) (4 wt.%) as catalyst initiator without the presence of catalystaccelerator. The effect of vinyl ester composition on theenhancement of mechanical and thermal properties of unsaturated polyester/vinyl ester blends was investigated.The polymer blends were characterized by Fourier Transform Infra Red (FTIR)spectroscopy, tensile testing, hardness testing, scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). IR spectra showed UP and VE peaks. The curing copolymerization reactionoccurred at vinyl (C=C) bonds. The addition of vinyl esters enhanced mechanical and thermal properties. The UP/VE blends showed homogeneous morphology, transparent and copolymer thermoset blend.

Objective: The rising popularity of gamification as an academic topic can be attributed to the growing affordability of Internet access through smartphones. One major challenge for gamification applications is maintaining student engagement and active participation. This research investigated whether students’ engagement and reading comprehension significantly correlated with using Quizlet for vocabulary learning at a public senior high school in Gresik. Method: This research used a correlational research design. The subject of this study consisted of 30 students who used Quizlet for vocabulary learning. The research instruments were a questionnaire and a data sheet on students’ reading scores collected from their teachers. The researcher used Descriptive and Pearson correlation through the SPSS Statistics 16.0 program to analyze the data. Results: This research revealed that students’ engagement was moderate while using Quizlet for vocabulary learning. Then, the correlation coefficient was 0.429*, and the significance 2-tailed value was 0.018. From the sig-value, there was a significant correlation between the two variables, and the correlation value showed that the correlation was positive in the moderate category. Students' engagement and reading comprehension while using Quizlet for vocabulary learning had a significant correlation with a moderate correlation, and this indicated that an increase followed most students' engagement increase in their reading comprehension. Novelty: This study significantly contributes to understanding how students' engagement influences their reading comprehension when using Quizlet for vocabulary learning. It also establishes a positive and statistically significant correlation with a coefficient of 0.429underscores that higher engagement levels correspond to improved reading comprehension outcomes.

Augmented Reality is a technology that is commonly used by businesses to market their products. The technology allows customers to test products online in order to deliver a more enjoyable purchasing experience. The study is aimed at investigating the impact of vividness and perceived informativeness, as a characteristic of AR, on brand attitude through perceived enjoyment. There are 204 respondents chosen using purposive sampling technique. They are women who used Augmented Reality when purchasing cosmetics online. The study used a path analysis with the assistance of Amos software. According to the findings, perceived enjoyment can strengthen the influence of vividness and perceived informativeness on brand attitude.
Research background: It is important for companies to pay attention to the value of co-creation in order to encourage innovation and the development of new products where the source of ideas for innovation and new products comes from consumers. Participation in value co-creation is voluntary and depends on the consumer’s willingness to be involved, so there needs to be motivation within the consumer to carry out value co-creation. Therefore, it is necessary to understand the consumer’s personality which can encourage co-creation. Purpose: This study aims to analyze the factors that influence online value co-creation in e-commerce platforms. This study attempts to examine the value co-creation that occurs online by emphasizing the interaction between consumers. In addition, the researcher examines the role of personality traits on value co-creation. Research methodology: The population in this study are consumers aged 16 to more than 40 years who have experience in purchasing products in e-commerce and have given ratings, reviews, or comments on products and services in e-commerce. The Purposive sampling technique was used to select the sample of 152 consumers. PLS-SEM was used as an analytical technique. Results: The results reflect that personality traits and beliefs are the driving factors for online co-creation. This study also reveals that trust does not act as a mediator in the influence of personality traits on value co-creation. Conscientiousness is the dominant trait in the influence of personality traits on trust and value co-creation. This study only uses two dimensions of personality traits, namely conscientiousness and agreeableness. Future research should consider using the five dimensions of personality traits. The implication of this research is to enrich knowledge about the factors that influence the occurrence of value co-creation online and it is projected for marketers to provide ease of use features for further co-creation. Novelty: This research discusses interactions between consumers in e-commerce as a form of co-creation that has not been widely done.

Energy is a very important in modern life and need innovations to develop it. One innovation is the application of energyfor storage devices, such as batteries, capacitors, fuel cells, etc. For 30 years, the application of the NASICON (Na1+xZr2SixP3-xO12) into the NASICON gas sensor material was successfully prepared by using solid-state method. The raw materials such as SiO2, Na2CO3, ZrO2, and NaH2PO4 with a little methanol were mixed in Ballmill equipment. The silica powder was made by the extraction of bagasse ash by using sol-gel method. The x-ray diffraction patternshowedthat the result of silica extraction was amorphous and the NASICON structure wassynthesizedto bemonoclinic. The scanning electron microscopy results indicated that silica had non-uniform surface morphology and the NASICON had good surface morphology only on the form of Na3Zr2Si2PO12. The ionic conductivty of NASICON wasshown on LCR Nyquist plot of the three compositions. The highest NASICON conductivity was found inthe composition of x = 2.0, i.e. 1.142x10-8 S/m.
