Social media serves as a platform or a new area for developing innovation responsive to business advancement. As individuals are the source of knowledge in organizations, individual learning is the focus of organizational learning and development. Ambidexterity is an activity that requires individual learning. The study was carried out in Greater Jakarta, Indonesia. A personal survey questionnaire with convenience sampling was used to collect white-collar workers in Greater Jakarta. Rasch Model Analysis, specifically Person Measure Analysis, was used to filter for bias in the responses because the data was collected through personal references or self-report questionnaires. Structural Equation Modeling (SEM) is used to test hypotheses based on the collected data. According to the statistical results, ambidexterity and social media learning experience significantly impact innovative behavior. It implies that ambidexterity and social media learning experience can improve white-collar workers' innovative behavior. Ambidexterity has a significant impact on the learning experience on social media. It implies that a person with greater ambidexterity will engage in more intense knowledge exploration and exploitation through social media. The study's findings also show that social media experience without ambidexterity has the least impact on innovative behavior. It implies that social media experience without exploratory and exploitative activities does not lead to innovative behavior.

Also, many companies used social media to create a social media community concerning the products and services provided to strengthen the company's brand. This study surveys as many as 231 respondents and data analysis uses the PLS method utilizing smart PLS software. The result reveals that the use of information technology that is getting faster with high-speed data accessibility enhances the intensity of interaction between the community member with the path coefficient value of 0.605. Furthermore, the use of information technology with high-speed data accessibility also increase the satisfaction of movie trailer viewers with the path coefficient value of 0.392 since it can provide excitement and entertainment. Besides, the increased use of information technology provides higher satisfaction to the audience. The results also show that the presence of a social media community could provide satisfaction for movie trailer viewers with a coefficient of 0.332. The availability of films in the community provides excellent interactive communication between users. This research has focused only on the use of information technology in the respondents who watch movie trailers and is limited to a region of East Java province, Indonesia. Further research is required to be performed, which focuses on different types of social media and context and needs to analyze the comment of the film viewer in order to provide a better benefit on the latest films and for the entertainment company.

Enzymatic assay, based on oxidation-reduction reaction catalyzed by alcohol dehydrogenase, is one of the methods used to determine ethanol concentration. The present study was directed to determine the exact amount of enzyme required to accomplish oxidation-reduction reaction so that the concentration of ethanol in the sample can be determined precisely and accurately. Results of the present study indicate that the lowest unit activity of the enzyme that can be used for ethanol determination is 4000 units/mL, even though longer incubation time compared to the original method was used to ensure reaction completion. Validation of the method confirmed that the assay have acceptable linearity range within 0.01 - 0.06% (v/v) of ethanol with correlation coefficient of 0.9999. Both accuracy and precision parameters fulfill the Association of Analytical Communities (AOAC) International requirement, and therefore can be accepted as a quantitative analysis method. Limit of detection and limit of quantitation for the modified method were 0.0017% (v/v) and 0.0056% (v/v), respectively.

This study attempts to investigate whether Social Media Marketing Activity (SMMA) carried out by companies / brands have a positive impact on their brand equity, e-WOM distribution on social media and customers' purchase intention. The objective of this paper is to investigate the impact of SMMA towards customers' purchase intention. The researchers tried to survey the results of previous studies to give more benefits to the readers and researchers in this area of study. Research data was collected using an online questionnaire survey of 114 participants of Instagram users in Indonesia. The results of structural equation modelling supported the current model’s validity and indicated a positive effect of SMMA towards brand equity. Moreover, brand equity had a positive impact on e-WOM; and e-WOM maintained a positive influence towards customers' purchase intention. Finally, SMMA also has showed a direct impact to customers' purchase intention.

This research aims to examine the influence of top management commitment on the operational performance through the mediating role of the green purchasing and ISO 14000 implementation. This study used a quantitative approach and collected data by distributing 70 questionnaires to textile companies located in the Central Java region, Indonesia. One respondent from the top management level, a manager or general manager represented each company. Off the 70, 48 questionnaires were returned and completed correctly. Data analysis used a partial least square (PLS) technique with SmartPLS software version 3.0. The results show that top management commitment has a significant influence on green purchasing, ISO 14000 implementation, and operational performance directly. The results also show that top management commitment also influences the operational performance through the mediating role of the green purchasing and the ISO 14000 implementation. Additional findings indicate that top management commitment contributes more influence on the operational performance through the mediating role of the green purchasing and the ISO1400 implementation than its direct influence. This study contributes to the current theory on supply chain management and paves the way for the practitioner in enhancing the operational performance of the textile industry.
