Purpose- The purpose of this research is to find out the impact of social media Instagram on microgreens’ product knowledge and purchase intention by using several components of the AISAS model.Design/Methodology- Respondents in this study were 15 to 45 years old and were followers of Instagram accounts that disseminate knowledge and market microgreens’ products. This study uses a simple random sampling method. This study employs a variance-based structural equation modeling (SEM) analysis, that is partial least squares (PLS). The data from this research were analyzed using SmartPLS 3.0 software.Findings- The results revealed that social media significantly affected attention, Interest, and Search. Search has a significant and positive impact on increasing knowledge of microgreens products. Knowledge of microgreens products has a significant impact on purchase intentions of microgreens products. Originality- This research produces new findings regarding consumer behavior on microgreens and their influencing factors. Practical Implications- The results of this study can be used as a reference to find marketing methods and develop the most effective strategies to attract microgreens consumers.
Dragon fruit stem is prone to the infection of various pathogenic fungi and Trichoderma harzianum had been reported as an effective biological control agent against plant pathogenic fungi. This study was aimed to evaluate the ability of T. harzianum in controlling various pathogenic fungi infecting dragon fruit stem. This study was conducted using Completely Randomized Design (CRD) with three replicates. Pathogenic fungi was isolated from infected dragon fruit stem, then characterized morphologically to identify the species of those pathogenic fungi. The isolated fungi were subjected to in-vitro and in-planta antagonistic assay containing T. harzianum culture. The resulted growth inhibition in each fungal isolate was observed for a week by comparing the diameter of pathogenic fungi. Based on morphological characteristics, the dragon fruit stem was predicted to be infected by several pathogenic fungi, such as Phytium sp. (isolate A), Fusarium sp. (isolate B), Alternaria sp. (isolate C) and Rhizoctonia sp. (isolate D). Result of in-vitro antagonistic assay showed that T. harzianum conferred different suppression efficacy against all isolated pathogenic fungi ranging from 59-66%. Moreover, application of T. harzianum in-planta had resulted promising fungal growth inhibition up to 50% against all pathogenic fungi.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
