Abstract. Semiotic analysis of advertising aims to uncover the hidden meanings behind visual and textual elements presented in promotional content. This study explores the semiotic features in smartphone advertising, focusing on Oppo as a case study. This study uses a comparative framework to analyze the similarities and differences between Oppo advertising and competing brands. The analysis is conducted through Charles Sanders Peirce's triadic model, consisting of representamen, object, and interpretant, as well as Roland Barthes' concepts of denotation and connotation. This study identifies symbolic, iconic, and indexical signs used in Oppo advertising to build brand identity and attract target audiences. Key findings reveal how visual elements, color schemes, and slogans emphasize innovation, premium quality, and emotional connection. Comparative insights highlight Oppo's differentiation strategies, such as integrating cultural nuances and leveraging aspirational imagery, to strengthen its market position. The results of this study provide a deeper understanding of how semiotic strategies influence consumer perception and purchasing behavior, as well as provide practical implications for marketers and advertisers. This study bridges the gap between semiotic theory and its application in modern advertising, providing a comprehensive perspective on the power of signs in shaping brand narratives.

PT. Pelayaran Cahaya Papua Dumai Branch is one of the companies operating as a Shipping Agency (ship agency) which provides domestic and international services. PT. Pelayaran Cahaya Papua also provides ship services such as ship needs (reflagging, fresh water, bunker), and also provides services for processing ship certificates that are entering their expiry date. The discussion presented in this paper is the Ship Sanitation Control Exemption Certificate (SSCEC) Certificate Extension Procedure at the Class I Port Health Office (KKP) by PT. Dumai branch of the Papua Light Cruise. In the Ship Sanitation Control Exemption Certificate (SSCEC) Certificate Extension Procedure, the company deals directly with relevant agencies, both government and private (companies). By having a good relationship with the shipowner (ship owner) who has been given the authority to make a Letter of Appointment (LOA) agreement to agent their ships, the Company can more freely convey information regarding ship certificates because information regarding ship certificates has a very important role in managing the arrival and departure of ships. To obtain data, the author used 2 (two) types of observation methods in collecting data, namely direct observation of field study and library study. Thus the author can conclude that the procedure for extending the Ship Sanitation Control Exemption Certificate (SSCEC) at the Class I Port Health Office (KKP) has been running smoothly.

This quantitative research uses a descriptive survey method. Data collection using non-probability methods and purposive sampling methods was carried out by distributing questionnaires to 100 followers of the Tik Tok account @shopee_id.

The results of hypothesis testing in this research show that the Social Media Marketing variable (X) influences the Purchase Interest variable (Y). This is proven by the tcount value of 8.914 > ttable 1.987 and the significance value = 0.000 < 0.05. So it was concluded that the level of significant influence of social media marketing variables on purchasing interest was 44.8%, while the remaining 55.2% was influenced by other variables not examined in this research.
