Abstract

The development of the business world has advanced very rapidly in the current era of globalization, where there is a lot of competition between companies that have the same business. One of the businesses that developed from the creations of children from the Gorontalo area is Karawo. Karawo is a symbol of Gorontalo's cultural identity, to this day not only has consumers in its own area but consumers outside the Gorontalo area. So it is important for companies to pay attention to attractiveness in terms of consumer purchasing decisions. Several factors that influence purchasing decisions include buyer awareness of a brand, product price and perceived quality. By using a mathematical model using a quantitative approach with a regression analysis method, it can describe whether there is an influence of brand awareness, price and perceived quality on consumer purchasing decisions at Gerai Rumah Karawo and the magnitude of the influence. The data collection technique was by distributing questionnaires to 68 respondents. The research results show that brand awareness, price and perceived quality simultaneously influence consumer purchasing decisions at the Rumah Karawo Outlet by 69.5%.

Abstract

Chicken meat spoilage during storage can be monitored and prevented using smart packaging that contains active antioxidant and antibacterial compounds. This research aims to determine the effect of shallot skin extract concentration on the antioxidant and antibacterial activity of anthocyanin cellulose films for active packaging development. The method used to test antioxidant activity was the DPPH (1,1-diphenyl-picrylhydrazyl) method, while the antibacterial activity test used the liquid diffusion method. Antioxidant activity test results showed that the cellulose-anthocyanin film has an IC50 value of 1.36 µg/mL which was classified as very strong antioxidant activity. The antibacterial activity thest showed that overall the cellulose-anthocyanin film could inhibit the growth of bacteria, both Staphylococcus aureus and Escherichia coli bacteria. Shallot skin extract can be used as anthocyanins source which have antibacterial and antioxidant activity for smart packaging development.
