Representative scales were established, based on the zoom level of Google Maps, for generating a catalogue of indicators from the scale-image relationship, into the Google Earth visualization system. It was possible to analyze some functionalities of the visualization system proposed, such as the depth of detail from image resolution and the images return. Therefore, samples of four land use were analyzed. Furthermore, to associate the multilevel mechanism of the visualization in Google Earth, a digital ruler was used as a tool that measures the pixels per inch into the screen. In consequence, it is possible to analyze the changing behaviour from one screen to another. With this, it is feasible to associate a specific mechanism to improve the relationship between the handling of several images covering a limiting territory, and the scales that best represents the themes described. Finally, 893 samples were analyzed in 32 points of the territory, between the coordinates 14° to 33° N and 86° to 119° W. Finally, the error percentage, the variance, and the standard deviation were estimated for determining the variation between the values calculated in different samples.
Infrastructure plays an important role in the tourism sector as a provider of facilities to provide facilities to tourist sites. The study area is in the Donorejo village, Central Java. Donorejo village has one of the most famous caves in Central Java, namely Goa Seplawan. The study was conducted with in-depth interviews with local residents and tourist visitors, as well as measurements and direct examination of the paths that are on site. Quality assessment of road conditions is carried out qualitatively. The assessment is based on the experience and standardization of each respondent which is then re-matched with the results of the study at the location and the Road Condition Index Matrix (RCI). There are three main paths to Seplawan Cave, namely through Hamlet Rejosari, Denansri, and Katerban. The main road passes through Hamlet Rejosari in good condition, but very steep. On the other hand, Denansri and Katerban hamlets have poor conditions. Road improvements have increasing the number of visitors to Goa Seplawan. In 2018 there were 9, 889 and in 2019 became 13, 882. This number shows that road construction has an impact on increasing the number of visitors at tourism sites in the Donorejo village.
Export activities are important to the economic growth of the country, especially for developing countries. The city of Cilegon in Banten Province is the main city for the manufacturing industry in Indonesia, mainly for its iron and steel products. This study aims to determine the proportion of exported goods for the manufacturing industry in the City of Cilegon and make suggestions for further development. Data used are BPS publications 2016-2020, LQ is calculated to know the basis of the economic sector in the city. According to the calculation, the manufacturing industry in the City of Cilegon shares 59.70%, the highest among other regions. Commodities that dominated the export trade are footwear, plastic products, iron and steel products, while the US, China, and Japan were the countries that had the highest FOB. To escalate export performance and intensity, it is necessary to consider market and competitors’ networks, improvement of education and transport infrastructure, along with environmental and social-cultural impacts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
