Abstract

This study aims to assess the effect of green open space (GOS) on the microclimate and thermal comfort in three integrated campuses namely Universitas Gadjah Mada (UGM), Universitas Muhammadiyah Yogyakarta (UMY), and Universitas Pembangunan Nasional (UPN) Veteran. In order to achieve the research objective, three main steps were conducted. First, we mapped the GOS area and density of the three integrated campuses using a high-resolution satellite imagery. Second, three microclimate parameters such as air temperature, relative humidity, and wind speed were measured to each detected green spaces in the morning (08:00 am), at noon (01:00 pm), and afternoon (5:00 pm). Subsequently, the results of microclimate measurements were used to calculate the level of thermal comfort using Thermal Humidity Index (THI) method. Third, we carried out statistical analysis to investigate the correlation between the distribution and the density of GOS and the microclimate conditions. The results showed that a negative (-) correlation occurred between the pattern and density of GOS with temperature and wind speed indicating that clustered GOS significantly reduces the air temperature as well as the wind speed. On the contrary, the relative humidity has been increased. UPN campus has the highest temperature and wind speed and the lowest humidity among other campuses. According to the results of THI, a 100% of the UPN areas are uncomfortable, while at UGM and UMY 42,08% and 11,28% of their area are uncomfortable, respectively. This study found that the existence of GOS has an effect on microclimate depending on pattern and density.

Abstract

Supported by a variety of diversity and landscapes, the development of tourism in the Petungkriyono area is growing rapidly. Optimizing ecotourism services in the Petungkriyono forest without disrupting the ecosystem and damaging the environment can be done by limiting the number of visitors at tourism sites. This study aims to find out information about the tourism capacity of some tourist attractions in the local forest. This study uses the Cifuentes model to predict the maximum number of visitor capacities that can be accommodated in a tourist attraction called Physical Carrying Capacity (PCC), Real Carrying Capacity (RCC), and Effective Carrying Capacity (ECC) with management capacity as a consideration. The results of the study show that from PCC calculations, which means a maximum number of visitors physically provided by the space, Curug Bajing has the highest number of visitors (1,365 people) in a day from four other tourist objects. Rogojembangan Coffee Shop has the fewest visitors (347 respondents). The highest number of RCC calculations is Curug Bajing tourist attraction (1,365 respondents), and the lowest is Rogojembangan Coffee Shop (346 respondents). In addition, ECC calculations show that the highest number of visitors is at Curug Bajing (1,364 respondents), and the lowest is at the Rogojembangan Coffee Shop (345 respondents). For the management of tourism, the results can provide insight into which tourist attractions require further development. Regarding the result, it shows that Curug Lawe tourist attraction has an exceeded carrying capacity, so our results provide a basis for local tourism management and stakeholders to develop more effective strategies in tourism in the local forest, such as controlling and managing the tourism area by limiting visitors, managing the facilities, waste management, and avoid the habitat of endemic fauna so that we can maintain forest sustainability while utilizing natural tourism in the Petungkriyono forest.
