Abstract

This study aims to analyze the impact of green policies and environmentally friendly supply chain management on the competitive advantage of manufacturing companies in North Sumatra through the adaptation of green technology as an intervening variable. The method used in this study is quantitative with the Structural Equation Modeling (SEM) approach using Smart PLS software. The data used in this study were obtained through a survey involving manufacturing companies in North Sumatra. The results of the study indicate that green policies and environmentally friendly supply chains have a significant effect on the adaptation of green technology, which in turn has a positive impact on the company's competitive advantage. This study also found that the adaptation of green technology acts as a mediator that strengthens the relationship between green policies, environmentally friendly supply chains, and competitive advantage. These findings indicate that manufacturing companies that implement green policies and manage their supply chains with an environmentally friendly approach can strengthen their competitive position through more efficient and environmentally friendly technological innovations. The implication of this study is the importance of green policies that support the adoption of green technology and environmentally friendly supply chain management in increasing the company's competitiveness in an increasingly competitive market.

Abstract

This study aims to analyze the effect of green marketing techniques on consumer purchase decisions through perception of product quality as an intervening variable in organic product companies in North Sumatra. The method used in this study is a quantitative method using Structural Equation Modeling (SEM) through SmartPLS software. The test results show that green marketing techniques have a significant effect on the perception of product quality, which in turn affects consumer purchasing decisions. In addition, the perception of product quality is proven to be a variable that mediates the relationship between green marketing and purchasing decisions. These findings indicate that companies that implement green marketing techniques can improve the perception of product quality, which ultimately encourages consumers to buy the product. This study provides important insights for organic product companies to optimize green marketing strategies to improve consumer purchasing decisions.

Abstract

This study aims to analyze the effect of Green HR on the Work Environment and Job Satisfaction of employees in environmentally friendly hotels around Lake Toba, as well as the effect of Harmonization of Digitalization of Tax Accounting on Community Economic Welfare through Digital Literacy.

Sustainability-based and environmentally friendly policies increase motivation and work comfort, which in turn increases employee satisfaction. In addition, the digitalization of tax accounting, supported by digital literacy, has a positive impact on improving community economic welfare. These findings support the theory that policies that prioritize sustainability, both in the fields of HR and taxation, can create better results in improving quality of life and work productivity. This study makes an important contribution to the development of policies that support sustainability and digitalization in improving economic welfare and job satisfaction.
