Abstract

Biodiesel is one of the most potential alternative energy for diesel machine since it isrenewable and environmental friendly. Biodiesel can be produced by transesterificationreaction of vegetable oil or animal fat with alcohol and catalyst addition. In this study,biodiesel was produced by transesterification reaction of waste cooking oil andmethanol using a CaO catalyst of blood cockle shells (Anadara granosa). Blood cockleshells (Anadara granosa) can be used as heterogeneous catalysts for biodieselproduction because it contains CaCO 3 that can be decomposed into CaO.Decomposition of the blood cockle shells as heterogeneous catalyst for biodieselproduction was carried out at 900 oC for 5 hours. The yield of biodiesel optimum was81.67% with 3% weight of catalyst, 1:15 of oil and methanol mole ratio, 3 hours ofreaction time and 60±2 oC of reaction temperature.

Abstract

This study aims to implement a strategic communication plan for a target brand at the international level, projected in relation to direct competition. This research uses a methodological design based on a descriptive documentary review with a deductive approach that utilizes secondary sources and surveys for in-depth analysis. In the digital era, communication and marketing strategies must adapt to market dynamics and evolving consumer preferences. Digitalization is changing brands' interactions with consumers, emphasizing personalization, two-way engagement, and the use of technology such as artificial intelligence. The target market for men's products is now more diverse, including men and individuals exploring gender fluidity, requiring brand strategies to adapt to this diversity. Surveys indicate that comfort and quality are the primary factors in selecting men's underwear, with price and design as additional considerations. Social media has a significant influence on purchasing decisions, even though the ideal images used by brands often do not represent everyday consumers. Technology enables more effective advertising and data-driven personalization. An effective communications strategy requires clear goals, detailed guidelines, and ongoing monitoring. By leveraging digital technology and social media and adapting product and marketing strategies, brands can build more personal and relevant relationships, increasing consumer satisfaction and loyalty.
