Abstract

This study examines the influence of advertising and service quality on the purchase decision of Traveloka online flight tickets among the people of Kupang, East Nusa Tenggara, Indonesia. A quantitative approach with a causal design was employed. The population consisted of all Kupang residents who had ever purchased flight tickets through Traveloka, and a sample of 96 respondents was determined using the Rao Purba formula. Data were collected through questionnaires and analyzed using multiple linear regression, t-tests, F-tests, and coefficient of determination. The results show that advertising has a positive and significant partial effect on purchase decisions (t = 2.801, p < 0.05), and service quality also has a positive and significant partial effect (t = 2.693, p < 0.05). Simultaneously, both variables significantly influence purchase decisions (F = 7.270, p < 0.05). However, the adjusted R² value is only 0.117, indicating that advertising and service quality explain just 11.7% of the variance in purchase decisions. Descriptive analysis shows that respondents perceive both advertising and service quality as high, with mean index scores of 87.3 and 82.6 respectively. The study concludes that while advertising and service quality are important determinants, other factors such as price, trust, and word-of-mouth likely play larger roles. Traveloka should maintain its advertising effectiveness and improve responsiveness to customer complaints. Future research should include additional variables to better explain purchase decisions.

Abstract

Strengthening the competitiveness of Small and Medium Enterprises (SMEs) through branding strategies is a crucial issue amidst limited market access and low product differentiation, particularly in local economy-based areas such as Rote Ndao Regency. This study aims to analyze the application of branding models to increase the selling value of SME products and identify relevant strengthening strategies based on local wisdom. The research employed a qualitative approach with a case study design, using data collection techniques such as in-depth interviews, observation, and document analysis with selected SMEs using purposive sampling. Data analysis was conducted through interactive data reduction, presentation, and conclusion drawing. The results indicate that the application of branding elements, including brand identity, positioning, brand communication, storytelling, and brand experience, significantly increases the selling value of SME products. SMEs that implement branding in a more structured manner tend to have higher perceived value, stronger market appeal, and broader market penetration capabilities. However, limited resource capacity, low branding literacy, and minimal use of digital technology remain major obstacles to optimizing this strategy. The implications of this research emphasize that branding is not merely a promotional tool, but rather a strategic asset based on internal resources capable of creating sustainable competitive advantage. Therefore, policy interventions such as intensive mentoring, strengthening digital capacity, and integrating local values ​​into branding strategies are needed to encourage the transformation of SMEs into more competitive markets.

Abstract

This study analyzes the legal inconsistency in the delimitation of continental shelf boundaries in the Timor Sea involving Indonesia, Australia, and Timor-Leste. It focuses on the contrast between the Indonesia–Australia Continental Shelf Agreement of 1972, which applies a special circumstances approach based on geological features, and the Australia–Timor-Leste Maritime Boundary Treaty of 2018, which adopts the median line principle in accordance with the United Nations Convention on the Law of the Sea (UNCLOS) 1982. This research employs a normative legal method, examining international treaties, legal doctrines, and relevant judicial decisions. The findings indicate that the difference in delimitation methods results from both the absence of trilateral negotiations and the evolution of international maritime law. The application of geological considerations in the 1972 agreement has led to a delimitation outcome that significantly disadvantages Indonesia, while the 2018 treaty reflects a more equitable and modern legal approach. This inconsistency creates legal uncertainty and raises concerns regarding fairness in the allocation of continental shelf areas. The study further demonstrates that Indonesia has strong legal grounds to seek renegotiation or adjustment of the 1972 agreement, particularly in light of the principles of equity and distance-based criteria under UNCLOS 1982. A consistent application of these principles is essential to ensure fairness and legal certainty in maritime boundary delimitation.
