Abstract

SubDAS Cibeureum merupakan bagian dari DAS Citarum. SubDAS Cibeureum merupakan bagian dari Kawasan Bandung Utara. Seiring pertumbuhan penduduk yang meningkat, pembangunan pun terus terjadi sehingga mengubah tutupan lahan dari hutan menjadi pemukiman, jalan, industri, bahkan kawasan ini sangat diminati untuk dijadikan tempat wisata padahal disisi lain area ini harus dilindungi karena merupakan kawasan resapan air. Selain perubahan lahan, perubahan iklim juga akan mempengaruhi potensi air. Oleh karena itu untuk melihat pengaruh perubahan lahan dan iklim terhadap potensi air dilakukan perhitungan ketersediaan air menggunakan metode neraca air thornthwaite. Parameter yang digunakan adalah data curah hujan dan suhu dari stasiun BMKG Bandung  tahun 2007-2017 dan data penutupan lahan Jawa Barat tahun 2009, 2012 dan 2017. Rata-rata curah hujan periode 2007-2009 sebesar 2084.7 mm/tahun, periode 2010-2012 sebesar 2664.3 mm/tahun, sedangkan periode 2013-2017 sebesar 2583 mm/tahun Rata-rata evapotranspitrasi periode 2007-2009 sebesar 1188.94 mm/tahun, periode 2010-2012 sebesar 1194.41 mm/tahun, dan periode 2013-2017 sebesar 1210.71 mm/tahun. Karena adanya perubahan lahan, maka koefisien run off meningkat dari 0.26 (2009), 0.31 (2012), dan 0.375 (2017). Dari hasil perhitungan didapat bahwa dari tahun 2007-2012, kawasan ini mengalami perubahan lahan yang mengakibatkan kenaikan debit run off dan perubahan iklim yang mengakibatkan kenaikan debit presipitasi efektif. Dan dari hasil penelitian didapat bahwa ketersediaan air meningkat pada tahun 2012 karena curah hujan yang meningkat cukup besar pada periode tahun 2010-2012

Abstract

The use of virtual reality as a marketing tool for conventional tourism has seen an increasing adoption, as it enhances the engagement between virtual tourists and the showcased destinations. This study evaluates the effectiveness of Virtual Reality (VR) in enhancing the tourism experience at Alamendah Tourism Village, Bandung. A quantitative approach was used, with data collected through structured questionnaires distributed to 385 potential tourists who had experienced the village’s VR tour. Structural Equation Modeling (SEM) was employed to analyze the relationships between system quality, immersive perception, authenticity, satisfaction, and visit intention. The analysis process was supported by the SmartPLS application. The results indicate that system quality significantly influences immersive perception and authenticity, which in turn affects tourist satisfaction and visit intention. Moreover, immersive perception was found to mediate the relationship between system quality and authenticity. This study concludes that investment in high-quality VR technology and the creation of authentic immersive content is essential for tourism village managers to enhance tourist engagement and satisfaction. These findings suggest that VR can optimize the unique features of tourism villages, such as cultural authenticity and natural beauty. Additionally, VR can offer a deeper and more fulfilling experience when enjoying tourism in the village. Therefore, the implementation of VR can serve as a strategic tool to boost tourist loyalty and long-term success in the tourism village sector.
