A Comprehensive Survey on Comparisons across Contextual Pre-filtering, Contextual Post-filtering and Contextual Modelling Approaches

Recently, there has been growing interest in recommender systems (RS) and particularly in context-aware RS. Methods for generating context-aware recommendations are classified into pre-filtering, post-filtering and contextual modelling approaches. In this paper, we present the several novel approaches of the different variant of each of these three contextualization paradigms and present a complete survey on the state-of-the-art comparisons across them. We then identify the significant challenges that require being addressed by the current RS researchers, which will help academicians and practitioners in comparing these three approaches to select the best alternative according to their strategies

KALIBIRU TOURISM VILLAGE DEVELOPMENT AS KULONPROGO ECOTOURISM

This article or writing aims to, 1) identify the potential and development of Kalibiru natural tourism, 2) assess the suitability of ecotourism development in the Kalibiru tourist area, and 3) develop a strategy for managing Kalibiru natural tourism for future plans. The problem is focused on the people of Kalibiru who are very dependent on the existence of the surrounding forest. The permit granted by the government for the use of community forests is the basis for the Kalibiru Nature Tourism organization in terms of the use of environmental services in protected forests. Proper management must be applied to prevent and reduce future side effects. To meet the needs of tourists, it is hoped that they will be able to develop ecotourism management so that they can meet the needs of tourists while still preserving nature. In order to approach this problem, theoretical references are used from natural attractions and tourism potential. The data were collected through the research data collection method by observing the assessment variables, collecting secondary data and interviews. The data that has been obtained will be processed and analyzed qualitatively. This study concludes that, 1) Kalibiru natural tourism has potential/feasible to be developed on condition that it continues to make improvements as well as improvements, especially in the accommodation, marketing and market share sectors so that tourism development can be maximized. 2) Kalibiru nature tourism is suitable for implementing ecotourism development, and 3) the strategies undertaken to develop Kalibiru ecotourism are categorized into 3 aspects, namely human resource developmen

Anthropocene monument as an ecotourism destination in the Special Region of Yogyakarta, Indonesia

Purpose — This study aims to analyze the procurement and processing of plastic waste from the Piyungan Integrated Waste Disposal Site (TPST) for the construction of Monument of Anthropocene (MoA) as a means of promoting ecotourism, while also examining the obstacles encountered during the monument-building process. Method — This research utilizes qualitative descriptive methods, which involve describing a phenomenon occurring within the community. The study was conducted at the Anthropocene Monument, employing data collection techniques such as observation, documentation, and interviews, with an interview conducted with the curator of the Anthropocene monument. The acquired data is analyzed using the Miles and Huberman analysis, encompassing data reduction, data presentation, and drawing conclusions. Result — The building process of MoA involves the use of bricks made from plastic waste. In addition to its function as a building, MoA serves as a multifaceted hub that fosters learning, exploration, information sharing, knowledge exchange, and collaborative efforts in production and work. MoA represents a form of ecotourism that showcases a strong sense of responsibility towards the environment and local culture by transforming plastic waste into valuable resources, both as raw materials in the form of bricks and as works of art. As an ecotourism site, MoA also offers three programs, namely art, culture, and circular economy. Contribution — This research makes a valuable contribution to the existing literature on ecotourism as an innovative approach to plastic waste management in less explored tourist areas in Indonesia. Moreover, the study specifically introduces MoA as a new and unique tourist destination

Pengelolaan Taman Wisata Umbul Square Berbasis Ekowisata di Kabupaten Madiun, Jawa Timur

– Umbul Square merupakan salah satu destinasi wisata yang terletak di Madiun, Jawa Timur. Salah satu daya tarik dari wisata ini adalah pemandian air panas alami yang berasal dari belerang. Selain memiliki pemandian air panas, Umbul Square ini ternyata memiliki nilai sejarah, karena umbul ini sudah ada dari masa pendudukan Belanda. Namun, dilihat dari segi pengelolaan, destinasi wisata ini memiliki wahana wisata yang menghasilkan polusi udara, sehingga bisa merusak alam yang ada di Umbul Square. Selain itu, belum adanya pengelolaan sampah yang tepat, sedangkan destinasi wisata ini memiliki nilai sejarah yang seharusnya dijaga kelestarian lingkunganya. Salah satu langkah yang tepat untuk mengelola kelestarian dari wisata ini adalah dengan mengelola secara ekowisata, selain memperhatikan aspek wisata, sosial dan ekonomi juga memperhatikan lingkungan. Penelitian ini menggunakan metode kualitatif deskriptif dengan analisis SWOT. Hasil penelitian diperoleh beberapa strategi pengelolaan yang bisa diterapkan, seperti melakukan pengolahan sampah dengan membedakan sampah sesuai kategori, meminimalisir penggunaan wahana yang menghasilkan polusi dan menambah atau mengganti dengan wahana-wahana yang ramah lingkungan serta hemat energi. Selain itu, pengelola juga bisa membuat Fasilitas pendukung dengan menggunakan bahan-bahan ramah lingkungan, seperti kayu, bamboo dan bahan alam lainnya
