Abstract

The existence of green open space in urban areas is very important in influencing the conditions of thermal comfort. The objective of this research was to analyze the relationship between green open space and human comfort for the city of Yogyakarta. We employed Temperature Humidity Index (THI) with input air temperature and relative humidity. The THI value was obtained from four green open space categories those are point, line, area and non-green space. The results showed that the green open space has a positive effect on lowering the air temperature through the cooling effect and providing more comfortable conditions than the place with non-green open space. Based on this research, the city of Yogyakarta could be categorized as quite comfortable.

Abstract

Green space area has contributed to increase atmospheric condition in surrounding area. Here we would like to test the cooling effect of small green area located in IPB campus Darmaga. We monitored air temperature at the morning (6 am) and afternoon (2 pm) for period March-June 2013 in three different sites in campus. Totally, we collected 658 observed data. Our results showed that partial shade area (PSA) and site were the most influenced factors that contributed to the cooling effect. It appears that the cooling effect was found until a distance of 50 m from each monitoring site.  The cooling effect varied among sites, but it is consistent that the maximum effect occurred during afternoon. Our analysis confirmed that PSA has contributed to the cooling effect until 28%. Other factors that contributed to the cooling effect were vegetation characteristics and geometric configuration of the canopy. Further, our findings revealed that greenspace area is valuable to minimize high temperature effect from traffic street.

Abstract

Tujuan dari penelitian ini adalah untuk menganalis pola hubungan ketersediaan ruang terbuka hijau dengan suhu di Kota Palu. Metode penelitian adalah berdasarkan data ekstraksi dan analisis matematis. Beberapa hasil penelitian yang diperoleh (1) bahwa kurun waktu 13 tahun dari tahun 1997 sampai dengan tahun 2010 ditemukan bahwa ruang-ruang hijau terbuka menurun dari 48,86% menjadi 29,48%, (2) penurunan ruang-ruang hijau terbuka yang diketahui akan meningkatkan suhu udara maksimalsecara signifikan, dan (3) Persentase ideal hutan kota adalah 18 648 ha (47%) dari luas kota Palu.Kata kunci : ruang terbuka hijau, suhu
