Abstract. This paper describes how collective memory and level of place attachment can be explored using social media data to develop a sustainable travel destination in the city of Yogyakarta. Yogyakarta is famous as a tourist destination city for tourism in Indonesia. One of the reasons why people visit an object at travel destination is to recall the memory of the place. Memory is important for creating memorable space and places as it differentiates one place to another. Memorable places could grow as a symbol and an identity of a district in the city. This paper explores the collective memories recorded as status in the social media. The study identifies the distribution of such locations or nodes representing the memory footprint of the city of Yogyakarta, which can be achieved by determining the quality level of nodes based on the level of place attachment. Analysis is done by looking at the number of caption status by location and time. Qualitative description is used to present the level of place attachment based on the content of the status captioned. The study shows that level of place attachment seems not to be influenced by the popularity of an object. However it affects how strong a travel destination might be sustainable in future development.

Abstract. Currently the concept of smart city comes not only at the level of discussion, but some cities have stepped in the stage of implementation. Many of promised benefits will be met for the needs of urban residents if the city applies this concept. Conversely, many professionals and scholars are still in doubt about readiness of a city in the application of this concept. Dimension of friendliness of the real city certainly will have some limitations in a smart city that relies more on interactions with information and communication technology (ICT). This new paradigm becomes background of this paper in viewing the friendliness dimension of a smart city based on city residents' perceptions. This paper uses case of 2 cities that have different level of readiness in the application of smart city. They are Yogyakarta City and Magelang City, both are located in Central Java. The method applied in this paper is quantitative method based on perceptual answer of respondents structured in a Likert Scale. Importance Performance Analysis (IPA) is then used to look at the attributes of smart city's dimension which will show the relationship of the level of city friendliness and the level of city readiness in an application of smart city. The result briefly shows that the level of city sensitivity in the application of smart city is very influential in viewing the friendliness of the city. The city that is better equipped to meet the needs of its population according to the dimensions of the smart city based on its existing characteristics has higher friendliness. Time period of applying a smart city concept as the City of Yogyakarta has done longer before Magelang City, is not a guarantee that the city then has a better level of friendliness. The urban citizens have appropriate affective aspect to articulate between what they need and what the city has provided.

This study aims to formulate a concept for an online rendering website based on renderers’ experience on using rendering software (V-Ray, Enscape and Lumion). Rendering software is essential to professionals (architects and 3D visualisers) and students alike. We conduct a survey of students, architects, and 3D visualisers regarding their rendering experience. There are various complaints about rendering: lengthy, costly hardware parts, and hardware incompatibility. We see a solution in providing an online-based rendering service on a website by implementing cloud computing technology. Accordingly, further research needs to uncover other possible solutions to provide the ultimate rendering experience.
