Abstract

Purwodadi Botanical Garden is an ex-situ plant conservation institute, as well as an educational and recreation media. One of efforts to enhance the service is to reduce the noise around. The aim of this study was to compare diversity of tree and groundcover in homogenous and heterogeneous vegetation, and to observe effects of vegetation heterogeneity in Purwodadi Botanical Garden on noise mitigation. This study was conducted in four area; mahogany area, teak area, low-density and high density heteregenous area. Parameters included vegetation quality and noise level measured with sound level meter. Results showed highest diversity index of tree were found in low density heteregenous area (2.66), which was slightly differet than that in high density heterogenous one (2.63). Meanwhile, diversity index was low in homogoneus area (<1.5). Diversity index of groundcover in high density heteregenous and mahogany area were moderate (2.92 and 1.70 respectively), whilst the other two were low. High density heterogenous area was considered the best area that shows noice attenuation to 46 dB with effectivity 104.55%.
