Abstract

Kappaphycus alvarezii is one of Indonesia's export commodities because it has high economic value as food and industry. One area in East Java which is the center of seaweed cultivation is Sumenep regency such as Saronggi and Bluto. Currently Sumenep Regency is an area for oil and gas exploration and exploitation. Types of pollutants resulting from these activities cause pollution in aquatic environments such as lead (Pb), mercury (Hg) and cadmium (Cd). The heavy metals found in the waters can be absorbed and accumulated in the seaweed thallus. The purpose of this research is to know the heavy metal content of Pb, Hg, Cd, chlorophyll-a, and cell morphology in E. cottonii in Bluto and Saronggi waters. This research is survey and descriptive research. The results showed that there are differences in heavy metal content of lead in E. cottonii, seawater, and sediments in Bluto waters and Saronggi waters. The waters of Bluto have a lower amount of chlorophyll-a than the Saronggi Waters. Cell wall thickness in E. cottonii in Saronggi Waters has thinner cell walls than Bluto waters. Measurement of water quality in Bluto and Saronggi waters through temperature, pH, salinity, brightness and DO parameters. The measurement results from both waters are not any striking difference and under optimal conditions.

Abstract

This study aims to examine the factors affecting the use behavior of the Flip.id application using the UTAUT2 framework. The results indicate that performance expectancy, effort expectancy, and social influence positively affect behavioral intention. Meanwhile, facilitating conditions and behavioral intention positively influence use behavior. The study found that facilitating conditions and performance expectancy are the strongest antecedents in this research. The findings also reveal a negative effect of hedonic motivation on behavioral intention, while price value does not influence behavioral intention to use the Flip.id application. The moderation testing of experience on facilitating conditions and hedonic motivation shows a positive relationship. However, perceived credibility does not moderate the relationship between behavioral intention and use behavior. Based on the findings, it is evident that the ease of application use, adequate facilities, usefulness, and recommendations play crucial roles in increasing behavioral intention. Conversely, emotional and financial aspects do not demonstrate significant importance for users. This study provides implications for Flip application developers to enhance functional features, user education, and other facilities that support transaction processes within the application.
