2019, International Journal of Engineering Research & Technology (IJERT)

Introduction: Noise is one of the problems that occur in cities and brings adverse effects to human health and the environment. Telajakan is one of the traditional green open spaces in Bali that physically provides beauty and fresh air also can be used as a noise barrier. Methods: This is experimental research with the aim to find differences in the intensity of noise inside and outside of Telajakan. The location of the study was in the city of Denpasar. Noise intensity is measured from two places. One meter in front of Telajakan and one meter behind Telajakan. Intensity of noise is measured by a sound level meter. Results: The average measurement results with a distance of one meter in front of the Telajakan are 53.0 ± 4.76 db. The average measurement results with a distance of one meter behind Telajakan are 38.25 ± 10.27 db. With the presence of Telajakan (green open space) there is a decrease in the average noise of 14.75 ± 8.22 db. Conclusion: Telajakan as a Balinese cultural heritage that can be used as a noise barrier. Telajakan as a green space Balinese architecture that is full of aesthetic, security, social and spiritual meanings. INTRODUCTION Noise is one of the problems that occur in cities. This is because it has a bad impact on humans and the environment. The lack of Green Open Space is one result of noise. Green open space not only functions as the lungs of the city, but green open space is also a noise barrier in cities. The sources of noise vary, ranging from buildings such as industrial plants and highways, that is the sound of vehicles. City Green Open Space is a part of urban spatial structure that functions as a green urban area that is physically beneficial, namely providing beauty and fresh air between the density of buildings and also socially beneficial as a place of interaction and social activities. However, the large level of urbanization in the city has an impact on the high utilization of space or land and has resulted in changes to the open space of the city. Telajak is one of the traditional open spaces (karang suwung and karang tuang) besides natah, the sanctity radius of the temple, setra, town square, and others. Telajakan is a line arranger between the roadside wall (penyeker) and a gutter (jelinjingan) which is decorated with traditional plants for spiritual and economic activities. Telajakan as a legacy of Balinese ancestry is a front garden of houses in Bali that is full of aesthetic meanings, security, social and spiritual meanings. 2 Telajakan is a strip of traditional green space between the wall of a housing compound and a ditch/pedestrian path in a roadside (Figure 1). The width of telajakan is determined by Balinese traditional architecture, which case between 1.0 and 2.2 meters, and by Bali Regulation No. 10/1999, which case between 0.5 and 2.0 meters. Traditionally Telajakan has multiple functions such as provision of plant and flower materials for Balinese daily rituals, regulation of storm water from the property, and offering semi-public space for street vendors and neighbors 6. With regards to the functions of telajakan, literature review shows that the primary functions of the plants in telajakan are religious and economic. Plants are used for religious ceremonies, medicinal purposes, spice, aesthetics, and micro economy. Telajakan provides a space to place the penjor during traditional ceremonies. 7
