This study examines the segmentation and targeting strategies employed by food delivery app providers in Jakarta. It aims to identify the key factors influencing consumers' intentions to continue using these services across different market segments. A cluster analysis modeling approach is applied to group consumers based on specific characteristics. The findings provide valuable insights for marketers to design strategies that better align with the unique needs of consumers, considering both demographic and psychological factors. This enables marketers to adopt a more targeted approach in effectively addressing the preferences of each consumer segment. Additionally, the study highlights the importance of understanding the dynamics of the evolving demand within Indonesia's food delivery service sector. Ultimately, the research not only supports app providers in enhancing customer satisfaction but also fosters stronger loyalty towards their services. By leveraging a data-driven approach and more precise segmentation, food delivery app providers can refine their marketing strategies to engage consumers in a more relevant and sustainable manner.

Tourism have a significant role in global economic development and is a key driver of sustainable development, particularly in developing countries like Indonesia. This study examines the relationship between tourist satisfaction, price sensitivity, and competitive sustainability within the context of Small and Medium Enterprises (SMEs) in Indonesia's tourism villages. Using a quantitative approach and structural equation modeling (SEM) with SmartPLS, the study analyzes data from SME actors in tourism villages. The findings reveal that tourist satisfaction positively influences competitive sustainability by fostering loyalty and repeat visits, which enhance the long-term viability of tourism destinations. Similarly, price sensitivity significantly impacts competitive sustainability, emphasizing the importance of strategic pricing in fostering competitiveness in the tourism sector. These results underscore the necessity for SMEs to prioritize service quality and adopt effective pricing strategies to remain competitive and sustainable in the evolving tourism industry. The study contributes to the literature by highlighting the interconnected roles of satisfaction and pricing in achieving sustainable competitive advantage for tourism SMEs.

This research aims to analyze environmental conditions in Jakarta and identify practical solutions to air pollution, water pollution, and waste management. The research methods include air and water quality monitoring with modern sensors, analysis of emissions data, and interviews with stakeholders. Simulation models evaluate the impact of various interventions, such as public transportation improvements and pollution control technologies. The research results show that Jakarta faces significant challenges, with pollutant concentrations often exceeding safe limits. Simulation models estimate that reducing vehicle emissions and using renewable energy could reduce air pollution by up to 30% within five years. Pilot projects such as sensor-based air quality monitoring systems and household waste separation programs are progressing positively. However, budget constraints and resistance to change are still obstacles. The conclusions of this research emphasize the importance of integrating modern technology, strengthening environmental policies, and active community involvement. This research also offers a model that can be implemented by other cities in developing countries. Suggestions include policy adjustments, increased financial support, and community education programs to increase awareness and participation in environmental improvement.

The culinary richness of an area is one of the attractions for tourists. Nowadays, quite a few tourists deliberately come to a destination to get the experience of enjoying delicious local and foreign food, to see firsthand the potential for authentic production. This research aims to test the influence of the variables destination image, food quality, and local food repurchase intention. The sample used in this research was Gen-Z who often do culinary arts with a total of 328 respondents. Research data was obtained from the results of filling out a questionnaire and analyzed using SEM analysis techniques with the help of the SEM PLS program. This research method is a quantitative approach, where the sample determination uses non-probability sampling with purposive sampling. The hypothesis will be tested using an ordinal scale on a Likert scale. Research hypothesis testing was carried out using a Structural Equation Model (SEM) approach based on Partial Least Square (PLS) to measure Validity and Reliability as well as the Structural Inner Model and Outer Model. The results of this research show that (1) Destination image has a positive and significant effect on repurchase intention for local food; (2) Food quality has a positive and significant effect on repurchase intention of local food.

This study aims to analyze the influence of trust, information quality and risk perception on online purchase decisions. This research is a quantitative research with a research design using exploration. The population in this study is the overall consumer of online shop services in South Jakarta. The sampling method in this study uses purposive sampling using the Roscoe (1975) approach in determining the number of samples. The data analysis method in this study uses SEM-PLS. Based on the results of the study, it was found that trust, information quality and risk perception play an important role in influencing online purchase decisions. It was also found that the perception of risk had a significant negative effect on purchase decisions.

The maximum potential of sustainable tourism development is significantly impeded by the 53 pilot tourism villages in Bogor Regency. In order to address the low percentage of tourist villages that are still pioneering, it is imperative to prioritize the enhancement of local communities' awareness and understanding of tourism. It is anticipated that the establishment of community-based tourism villages will bolster the local economy, enhance community welfare, and promote local wisdom as a critical component of sustainable tourism initiatives. The purpose of this research is to investigate the impact of governance, social welfare, and local community involvement on sustainable tourism villages. Quantitative research techniques are employed to provide more thorough, valid, trustworthy, and objective data. The samples were collected from 259 village communities in six experimental pioneering tourism villages in Bogor Regency. Factor and regression analyses were used for the data analysis. The study's findings indicated that the sustainable tourism village is positively correlated with governance, social welfare, and local community involvement. The strong relationship between these factors underscores their importance in promoting the success and desirability of tourist villages.
