Nipah Panjang Village in Kubu Raya Regency, Indonesia, has diverse mangrove forest vegetation. Meanwhile, the mangrove forest in Nipah Panjang Village has the potential threat of deforestation, so it is necessary to develop a management strategy. A mangrove management directive can be compiled with mangrove biophysical data and the social conditions of the surrounding community. Therefore, this study aims to examine the distribution of mangrove forest areas and their utilization by the community in Nipah Panjang Village. The method used in this study was GIS analysis to determine the distribution of mangrove forest areas. In this study, observations and interviews were carried out to determine the use of mangrove forests. The study results show that from 2013 through 2018, there was around 3.12 Ha of deforestation. Deforestation that occurred was much lower than the previous year. It was due to the implementation of a devolution policy that granted village forest permits in Nipah Panjang Village. Currently, the forms of utilization of mangrove forests in Nipah Panjang Village are the farming (apiculture)  of kelulut honey, forest honey farming, and crab farming with the concept of silvofishery and the development of ecotourism. This form of utilization needs to be maximized so that the community's welfare increases, ultimately maintaining the mangrove forest.

Indonesia’s coastline, particularly Kendal Regency in Central Java, faces critical mangrove degradation due to land-use changes and rising sea levels. This study aims to asses the condition and erosion impacting Kendal's mangrove ecosystems to inform future conservation strategies. Using remote sensing technology, multi-spatial and multi-temporal imagery from 2005–2023 was analyzed and validated with field observations to evaluate mangrove species composition, structure, and land changes. The mangrove area increased by 52% in three locations, with the Bodri River delta (Pidodo Kulon and Pidodo Wetan villages) showing the most significant growth at 76.69 hectares. Ngebum Beach (Mororejo) had the largest proportional increase, reaching 185%. The ecosystems are moderately diverse, containing at least 11 mangrove species, though Rhizophora dominates due to extensive planting efforts. Despite stable conditions, these ecosystems face threats from deforestation for aquaculture, the primary driver of land erosion, compounded by rising sea levels. Although mangrove areas have expanded significantly, ongoing challenges include erosion, anthropogenic pressures, and limited species diversity. Future strategies must involve multi-stakeholder collaboration to implement sustainable practices, promote species diversity, develop erosion mitigation models, and conduct awareness campaigns to ensure the resilience of Kendal’s mangrove ecosystems.

The hotel industry is currently facing a digital transformation driven by technological advancements and changing consumer behavior. This research aims to explore how digital transformation in hotel management can optimize the guest experience in the industry 4.0 era. The research methodology primarily relies on a comprehensive literature review and analysis of industry documents to provide a robust and broad foundation for this study. The findings indicate that integrating technologies such as property management systems (PMS), Internet of Things (IoT), artificial intelligence (AI), and data analytics can enhance operational efficiency, service personalization, and data-driven decision-making in hotel management. However, the implementation of digital transformation also faces challenges, such as significant investments, cybersecurity, and resistance to change. Case studies of hotels that have successfully adopted digital technologies reveal best practices and valuable lessons, including the importance of top management support, strategic alignment, and stakeholder engagement. This article contributes to the literature by integrating the diffusion of innovation (DOI) theory and the technology acceptance model (TAM) to develop a conceptual framework that explains the adoption and success of digital transformation in hotels. The research findings have practical implications for hotel managers in designing and implementing digital transformation initiatives. Although this research primarily relies on secondary data sources, future research can adopt a multi-method research design incorporating primary data to provide further insights into this phenomenon.

Jembrak In this era of globalization, service is the main key in building positive relationships between service providers and consumers. One of the critical aspects in providing services is attitude or Service Attitude, namely the attitude shown by individuals or organizations in providing services to the community.
