Formaldehyde is a carcinogenic compound that harmful to health and often misused as a food preservative in Indonesia. However, in most of the foods including fish, formaldehyde can be formed endogenously or naturally during storage. Recently, Moonfish (Lampris guttatus) from Indonesia has been exported. Meanwhile, during delayed transportation to importing countries, moonfish need to be kept frozen up to several months This condition leads to the formation of formaldehyde. The aim of this research is to study the pattern of endogenous formaldehyde formation in moonfish during the frozen storage period. The study was conducted by observing the formation of endogenous formaldehyde as well as the formation of DMA (dimethylamine), TVB (total volatile base), TMA (trimethylamine), and TMAO as parameters related to the formation of endogenous formaldehyde in moonfish. The parameters were observed periodically shortly after the fish died until six months in frozen storage. The results showed that the content of formaldehyde, TVB, TMA, and DMA in moonfish during six months of frozen storage increased every month. The formation of natural formaldehyde in the moonfish was inline with quality degradation. Moonfish is still suitable for consumption based on its freshness level up to one month in frozen storage, but based on the formation of formaldehyde, the level of consumption should consider the calculation of maximum daily intake based on specified reference dose.

This study aims to determine the effect of expectancy effort, social influence, performance expectancy, website design, experience, Internet banking and Internet usage skill in the use of Internet banking in Bandung Raya, Indonesia. Partial Least Square was used to examine the model used in this study. The results show that expectancy effort does not have a significant effect on performance expectancy in the use of Internet banking, social influences do not have a significant effect on performance expectancy in the use of Internet banking but performance expectancy has a significant effect on effort expectancy and social influences in the use of Internet banking. Website design has a significant influence on the behaviour of Internet banking websites. Website design has a significant impact on the use of Internet banking through mediation of performance expectancy. Prior experience has a significant effect on effort expectancy in the use of Internet banking. Prior experience has significant influence performance against expectancy in the use of Internet banking. Prior experience has a significant effect on website design in the use of Internet banking. Internet skill does not have a significant effect on performance expectancy in the use of Internet banking. [ABSTRACT FROM AUTHOR]
