Abstract

North Sumatra is one of the provinces in Indonesia that has a wealth of natural resources in the form of natural beauty.  One place whose potential natural beauty stands out is the Simarjarunjung area, which is on the north side of Lake Toba. The purpose of this study was to analyze the spatial distribution of tourist objects, natural tourism amenities, and infrastructure in the Simarjarunjung nature tourism area. This research method uses spatial analysis. There are 11 tourist attractions located in the Simarjarunjung natural tourism area that have the potential to be utilized by the manager for natural tourism activities. My Maps technology from Google is used to facilitate access to information so that it is expected to have a positive impact. One of them is the promotion of tourist attractions so that they can be easily accessed by anyone through online networks. The availability of data on the distribution of tourist attractions, attractions and facilities / infrastructure resulting from this research is expected to be a means to be able to increase visitor access to find out information about tourism contained in Simarjarunjung tourist attractions. Each tourist attraction in the Simarjarunjung area has various attractions and tourist facilities, each of which is the attraction and uniqueness of each tourist attraction

Abstract

The Gunung Leuser National Park (GLNP) area, among others, consist of tropical lowland-forest ecosystems that becomes the habitat of Sumatran orangutans (Pongo abelii). The GLNP is located at Aceh dan North Sumatra Provinces and lies on 830,268,95 hectares of land. To date, the area is not free from the pressure of forest degradation, such as encroachment and land conversion to plantations. This is a perturbing condition, especially concerning the biodiversity in its lowland-forest ecosystem. The vegetation composition that renders the succession of Sumatran orangutans in the GLNP lowland-forest was obtained by conducting vegetation analysis on the restoration sites in the forest. The analysis method adopted on this research was the grid-path method. Two transect lines, 1,000 metres each, were made for this purpose. Each line consisted of 10 plots with a distance of 100 metres between plots. The measurements were made on the growth rate of seedling, sapling, pole, and tree. The data were then processed to determine the Important Value Index (IVI), Diversity Index, Richness Index of vegetation, and Dominance Index of the research area. The results showed that the vegetation composition that rendered the succession of lowland-forests of GLNP consisted of 58 species and 26 families. Ficus fistulosa had the highest IVI at the growth-stages of seedling and sapling. And Macaranga tanarius had the highest IVI at the growth-stages of pole and tree. The species Diversity Index (Shannon-Wiener index) of the vegetation on the restoration site in lowland forests of GLNP showed moderate values at the growth-stage of seedling and pole, and high values at the growth-stages of sapling and tree. The Richness Index of vegetation showed moderate values at the growth-stages of seedling and pole. As for at the stages of sapling and tree, it showed high values. The Dominance Index of the restoration site in lowland forests of GLNP showed high values at all growth-stages.
