Abstract

In an attempt to maintain customer loyalty to Madame Gie Cosmetic, it is necessary to innovate in promotion and marketing. Factors that can affect customer loyalty are brand personality and celebrity endorsers which are also related to brand trust variables. So, the purpose of this study is to examine the effect of brand personality and celebrity endorsers on customer loyalty through brand trust on Instagram followers of the Madame Gie Cosmetic brand.  The approach used is quantitative research with descriptive explanatory and questionnaire filling methods. Research data obtained from 320 respondents. Data processing is done using Smart-PLS software.  Data were analyzed by descriptive analysis, outer model, inner model and hypothesis testing with t-statistic value for alpha 5%. The results of this study are Brand personality has a positive and significant effect on customer loyalty and brand trust.  Celebrity endorsers have a positive and insignificant effect on customer loyalty and brand trust. Brand trust has a positive and significant effect on customer loyalty. Brand personality and Celebrity endorsers have a positive and significant effect on customer loyalty through brand trust. While the general relationship between brand personality, celebrity endorsers, and customer loyalty has been explored in previous studies, the specific findings of this research contribute to the existing knowledge in several ways: Mediating role of brand trust and Specificity to Madame Gie cosmetics. The contribution of these findings may help theoretical advancement, practical implications, and specific insights for Madame Gie cosmetics. In summary, the novelty of the study lies in its identification of brand trust as a mediator, while its contributions include theoretical advancement, practical implications, and specific insights for the brand.

Abstract

Energy sustainability is crucial for mitigating climate change and reducing dependence on fossil fuels. This research evaluates a hybrid renewable energy system combining photovoltaic (PV) technology and wind turbines to meet the electricity demand of Wahid Hasyim University's Faculty of Engineering, totalling 555,000 VA. Using HOMER Pro software, the study identifies the optimal configuration based on technical, economic, and environmental aspects. The hybrid system integrating PV, wind turbines, batteries, and converters achieves the lowest Net Present Cost (NPC) of $214,877 and a Levelized Cost of Energy (LCOE) of $0.0185/kWh, outperforming grid-only systems. Environmentally, the system significantly reduces carbon dioxide (CO2) emissions, from 559,226 kg/yr in conventional systems to 62,452 kg/yr. Solar energy contributes 56% of electricity generation, leveraging stable solar radiation of 4.28–5.54 kWh/m²/day. Additionally, an annual surplus of 156,350 kWh can be sold back to the grid, enhancing operational efficiency. This study demonstrates that hybrid renewable energy systems deliver long-term cost efficiency and significantly mitigate climate impacts. It provides a sustainable energy model for campuses in Indonesia and worldwide, particularly in regions with abundant solar resources.

Abstract

Purpose: Increase the added value of coconut fiber waste in Rejosari village by processing waste using appropriate technology into cocopeat products. Method: This service activity uses the Participatory Rural Appraisal (PRA) Model method, Participatory Technology Development Model, Community Development Model and Education in the implementation of its activities. Practical Application: The use of appropriate technology is expected to facilitate the processing of coconut coir waste into cocopeat. This technology can help process coconut fiber into fine granules in a short time. Conclusion: The application of appropriate technology in processing coconut coir waste into cocopeat can increase the value of the waste which was initially less than optimal. The processing of coconut fiber waste into cocopeat is expected to increase the income of the Rejosari Village community.
