Northern Bandung Area (KBU) plays a vital role and function to surrounding areas as a groundwater catchment area. The West Java Province Spatial Plan (RTRW) stipulates KBU as the Provincial Strategic Area (KSP) for environmental protection. The spatial control governance over the KBU is currently regulated by the Governor Regulation Number 2 Year 2016 about Guidelines for Controling the Northern Bandung Area as the the West Java Province Strategic Area. The KBU development ought to take environmental carrying capacity into account concerning the completion of environmentally based spatial use programs in the KBU. This study aimed to analyze the environmental carrying capacity of land use, and to formulate program recommendation of desired spatial use in KBU. Conservation index method was used to analyze environmental carrying capacity necessary to spatial use program recommendation. The results showed that the land use coverage in 2015 decreased actual conservation function, creating an increase of critical conservation areas by 68.37% and by 69.78% in 2018. In contrast, the conservation index on the land use plan in the RTRW showed a decrease in critical conservation area to 35.90% in 2029. However, such a declining figure has not been supported by environmental programs in the land use plan implementation required to increase the good conservation class by 42.27% while it recorded by 10.78% in 2018. It can be concluded that the IKA and IKC studies showed a distribution expansion of critical lands in KBU, and the IKR analysis proved that the land use plan in the RTRW would reduce critical conservation areas.

Objective: This study aims to identify the potential of traditional cultural arts and their interaction with sustainable tourism in the UNESCO Geopark Ciletuh-Palabuhanratu Geopark through the Parahyangan Cultural Panglayungan Cibenda Village, Ciemas District, Sukabumi Regency. Theoretical framework: The research is centered on exploring how tradition and sustainability can be integrated into the development of tourism destinations, particularly in the Ciletuh Pelabuhanratu Geopark, utilizing the concepts of Sustainable Tourism Development and Traditional Values in Tourism. Method: Through research with a qualitative approach based on the Huberman and Miles model which aims to obtain valid and reliable results, using data triangulation in the form of crosscheck of sources. Results and conclusion: Furthermore, it was obtained that traditional cultural arts have an interrelation and interaction with sustainable tourism, namely the positive impact on traditional cultural arts activities with environmental and environmental sustainability, economy, and social life of the community.   Originality/value: The development of geoparks as sustainable tourism destinations is becoming a priority considering the nature and characteristics of these destinations that emphasize attention to a number of aspects such as economy, environment and preservation (including culture), as well as the empowerment of communities around the destination. This is in line with the location of the geopark which is always in a rural area rich in natural tourism and local culture. However, research on art, culture and tourism, it seems that more specific and specialized research on art, culture, and tourism is still not widely done.

This study explores how Instagram is utilized as a strategic communication tool to campaign for environmental engagement, specifically in promoting river cleanup initiatives among youth audiences. By employing a quantitative content analysis of eleven Instagram posts related to river cleanup efforts conducted between December 2024 and June 2025, we examine audience interaction metrics such as views, reach, likes, and engagement across different age groups. The findings highlight that the 18–34 age demographic is the most responsive to environmental messaging on social media, accounting for over 70% of total engagement. Posts featuring direct community involvement, promotional content, and educational messaging were identified as key content pillars driving higher interaction rates. These pillars demonstrate the importance of message framing in digital environmental advocacy. The study affirms Instagram’s potential as an effective platform for fostering eco-conscious behavior and youth participation through visual storytelling and targeted communication strategies.

Research mapping related to river revitalization has been carried out on areas experiencing severe pollution to provide a roadmap for knowledge and answers to a number of environmental issues surrounding rivers. Therefore, this study aims to map a number of research publications regarding the Citarum River, which is an important area for people in West Java. This river is currently the most polluted in Indonesia, which led to the implementation of the revitalization program initiated by the government known as "Citarum Harum". The bibliometric method was used in this research to determine annual trends, keywords, field grouping, and location. The results showed a fluctuating increase in the number of research publications on the Citarum River. Furthermore, the mapping results showed that topics, study groups, and locations related to this river were unevenly distributed. These findings indicated the need for coordination from the “Citarum Harum” program coordinator or government to develop a research roadmap and direct the researcher to examine topics and raise issues related to locations that are yet to be studied.
