Abstract

The objective of this study is to examine the effect of trust, income, and product knowledge on female college students in their purchase of Wardah cosmetics in Malang City. This research is based on the competitive landscape of the cosmetic market in Indonesia, where access to foreign cosmetic products whose halal status is not guaranteed is very easy. Therefore, the researcher aims to investigate the effect of several selected variables on the purchase of Wardah, a local cosmetic brand that has been certified as halal. This study used a quantitative research design, with the independent variables being trust (X1), income (X2), and product knowledge (X3), and the dependent variable being product purchase (Y). The analytical method used is multiple regression analysis by processing data from 40 respondents in Malang City. The results of the study showed that the income variable (X2), based on its indicators, had a positive and significant effect on the product purchase variable (Y), while the trust variable (X1) and product knowledge variable (X3) had a positive but insignificant effect on product purchase (Y). The researcher concludes that the purchase of Wardah cosmetic products by female college students in Malang City will increase if trust, income, and product knowledge also increase.

Abstract

This study aims to assess the impact of demographic and socio-economic factors on the volume of waste generated in districts/cities in East Java during the 2019-2023 period. The analysis was conducted by considering the population variable as a demographic factor, as well as the average level of education and Gross Regional Domestic Product (GRDP) per capita as socio-economic factors. Waste is one of the main challenges in environmental management, where suboptimal handling can have adverse effects on health, ecosystems, and the economy. This study aims to analyze how socio-economic and demographic factors affect the amount of solid waste generated by the community and also as a basis for the use of variables that can be used for a more effective and efficient predictive model of future waste generation. This study applies the panel data regression statistical method to evaluate the relationship between demographic and socio-economic aspects and the amount of waste, while illustrating the impact of economic activity and social conditions on the environment. The results show that population as a demographic element, as well as education level and GRDP per capita as socio-economic indicators, have a significant positive influence on the amount of waste generated by the community. The results of this study can support policy implications in encouraging new strategies to reduce waste generation and integrate environmental governance.
