Abstract

As an essential non timber wood product in Indonesia, optimization of cajuput (Melaleuca cajuputi) development can be determined through land suitability studies. BKPH Yogyakarta is a government organisation that managing forest area in Daerah Istimewa Yogyakarta Province. Playen Forest Area is one of BKPH Yogyakarta managing area that used for developing cajuputi. Geographic Information System (GIS) is one of the tools that can be used to handle spatial data. The purpose of this study was to determine the distribution of land suitability classes for cajuput in BDH Playen. A parametric approach was used to determine the land suitability class. Two methods in the parametric approach used are the storie and root square land index. From the research, the land index value of the stories equation tends to be smaller than the root square equation. The results of the root square method are considered more relevant to the conditions in the field, where the cajuputi stands in BDH Playen can still produce commercially. There are 3 (three) land suitability classes for cajuput in BDH Playen, namely marginally suaitable (S3), currently not suitable (N1) and permanently not suitable N2. The broad percentage of the total land suitability classes S3, N1 and N2 is 61.7%, 16% and 22.3% respectively. Rainfall becomes a limiting factor in all three classes of land suitability. In the land suitability class N1 and N2 there are several limiting factors, namely the problem of soil tends to be alkaline, shallow soil depth, drainage is hampered.

Abstract

Cities have a common characteristic in the form of land utilisation, which is dominated by built -up areas. Tourism is an essential aspect of city development because it can involve the identity of the city. Historical buildings, landmarks, shopping centres and museums are generally interesting places for tourists to visit. Yogyakarta, the research area, is synonymous as a city of culture and of students. Knowledge of the spatial clustering patterns of tourists can be one of the references for urban development. Social media data were used in the study as an alternative to direct data collection, which requires considerable resources. Flickr and Twitter were used as proxies to dete rmine the distribution of tourists, and the DBSCAN and HDBSCAN clustering algorithms were used to determine the centres of tourist activity. Furthermore, Flickr data were analysed temporally to determine the impact of the COVID-19 pandemic on tourism in Yogyakarta City. The clustering of social media data results shows that there are several city hotspots, besides the already well -known tourist attractions. Apart from city landmarks, several other tourist hotspots were revealed through the clustering process, such as accommodation, shopping centres, entertainment venues and souvenir shops, which also support tourism activities. The impact of COVID-19 on tourism in Yogyakarta City can be reflected through the number of uploaded photos by tourists on Flickr, which has decreased since March 2020. [ABSTRACT FROM AUTHOR]
