Komodifikasi Berita Iklan Natif Tumpahan Minyak Pertamina pada Program Berita Metro TV
Native advertising has been used in television programs that are inserted in news programs that discuss real problems. Native advertising does not highlight the promotional or commercial aspects by adopting the form and function of the news. This study aims to analyze the mechanism of using native advertising in the news of the Pertamina crude oil spill on Metro TV. Using the framework of Vincent Mosco's Media Political Economy Theory, this study dissects how news content is transformed into an economic commodity that serves the interests of advertisers. The research was conducted through a qualitative approach with a case study method, using in-depth interview techniques, analysis, and observation of news broadcasts. The results of the study show that Pertamina's oil spill news has undergone an intensive process of content commodification through a built-in content format and formed political economic relations that are able to intervene in the newsroom. This relationship resulted in a softening of journalistic narratives that prioritized the company's positive image. This process proves that the political economy mechanism through native advertising has converted the function of social media control into an instrument of corporate image recovery.

Review on Polyurethane Solubilization in Deep Eutectic Solvents (DES) for Plastic Recycling
Deep eutectic solvents (DES) are a novel category of environmentally friendly solvents created by the interaction of hydrogen bond donors (HBDs) and acceptors (HBAs) in precise molar ratios, exhibiting unique physicochemical characteristics. DES have low volatility, non-flammability, and great stability, making them ecologically benign substitutes for traditional solvents. The essential physical qualities of DES, including density, viscosity, and thermal stability, are pivotal to its operation. These characteristics are affected by parameters like as temperature, component mix, and molar ratios, enabling customisation for particular purposes. DES have shown considerable promise in several domains, including electrochemistry, material synthesis, and environmentally friendly chemical processes, owing to their adaptability and safety. In the realm of polyurethane (PU) solubilisation, deep eutectic solvents (DES) have notable potential. The solubilization process is ascribed to the breakdown of the polymer’s hydrogen bonds and the dissolving of urethane connections by the DES components, helped by their strong hydrogen bond network. By customising DES characteristics, researchers may enhance the breakdown process for PU, offering a sustainable solution to plastic waste issues. The basic features, physical and chemical properties, wide range of uses, and potential for developing PU solubilisation technologies of DES are highlighted in this paper.
