Judul: Vegetation Analysis as Microclimate Control and Noise Reduction in Bogor Botanical Gardens
Abstrak: Bogor Botanical Gardens has several functions, such as education, conservation, environmental services, and tourism. In addition, the Bogor Botanical Gardens is also one of the green areas that are functioned to maintain the environmental quality of Bogor City. The purpose of this study was to analyze the level of comfort with microclimate parameters (temperature and humidity), vegetation density and analyze the effectiveness of vegetation in the Bogor Botanical Gardens in reducing noise and compare it with the applicable noise standards. The research method used is direct observation data, in the form of microclimate data (temperature and humidity) and noise levels. The distribution of temperature and humidity is a parameter in seeing comfort in KRB, which is calculated by the Temperature Humidity Index (THI) dan Heat Stress Index (HSI) equations. Measurement of microclimate values (temperature and humidity) and noise at 3 measurement locations (inside and outside the park), using digital anemometers and sound level meters. The results showed that the distribution of THI values above 26°C indicated that the Bogor Botanical Gardens was in the uncomfortable category. Heatstressisstill under the hazard category and vegetation is quite effective in reducing noise at all measurement points. The condition of the Bogor Botanical Gardens does not function well as a city park forthe purpose of controlling microclimate, but it is effective in reducing noise. Distribution of heat stress index values with warning and extreme warning categories and still in the non-hazardous category. The composition of the vegetation can be added by the presence of a garden dividing wall with a road, it can reduce noise at least 7% dBA from the noise source and a maximum of 30% dBA from the noise source at all measurement points.

Judul: Ecological Analysis Of City Parks For Sustainability In Bogor City.
Abstrak: Taman kota sebagai salah satu jenis ruang terbuka hijau publik memiliki peran penting dalam meningkatkan kualitas lingkungan perkotaan dan mendukung keberlanjutan kota. Untuk mengetahui sejauh mana pelaksanaan fungsi ekologi dan persepsi serta preferensi masyarakat perlu dilakukan evaluasi secara menyeluruh terhadap aspek-aspek tersebut. Penelitian ini bertujuan untuk mengidentifikasi vegetasi, menganalisis kesesuaian fungsi ekologis, dan menganalisis persepsi pengguna dan preferensi terhadap lanskap di setiap taman untuk kelestarian Kota Bogor. Penelitian ini berlokasi di tiga taman di Kota Bogor, yaitu Taman Heulang, Taman Sempur, dan Alun-alun Kota Bogor. Metode penelitian ini dibagi menjadi dua metode yaitu analisis fungsi ekologis dan analisis persepsi dan preferensi pengunjung pada masing-masing taman. Fungsi ekologis akan dianalisis dengan membandingkan kondisi eksisting dengan kriteria baku fungsi ekologis, sedangkan analisis persepsi dan preferensi masyarakat mengenai ekologis taman akan dianalisis dengan pengumpulan data melalui kuesioner. Hasil evaluasi ini menunjukkan bahwa Taman Heulang merupakan taman terbaik dalam hal pengurangan kebisingan, modifikasi temperatur (teduh) dan fungsi penahan angin. Taman Sempur memiliki vegetasi yang cukup baik dalam memenuhi fungsinya sebagai pengubah suhu (teduh) dan pengatur kelembaban. Alun-alun Kota Bogor merupakan taman terbaik dalam hal fungsi pengatur kelembaban udara dan cukup baik dalam fungsi penahan angin dan pengurangan kebisingan., City parks as a type of public green open space have an important role in improving the quality of the urban environment and supporting city sustainability. To find out the extent of the implementation of ecological functions and the perceptions and preferences of the community, it is necessary to carry out a comprehensive evaluation of these aspects. This research aims to identify vegetation, analyze the suitability of ecological functions, and analyze user perceptions and preferences for the landscape in each park for the sustainability of Bogor City. This research was located in three parks in Bogor City, namely Heulang Park, Sempur Park, and Bogor City Square. This research method is divided into two methods, namely ecological function analysis and analysis of visitor perceptions and preferences in each park. Ecological function will be analyzed by comparing existing conditions with standard criteria for ecological function, while analysis of community perceptions and preferences regarding park ecology will be analyzed by collecting data through questionnaires. The results of this evaluation show that Heulang Park is the best park in terms of noise reduction, temperature modification (shade) and wind barrier function. Sempur Park has vegetation that is quite good at fulfilling its function as a temperature changer (shade) and humidity regulator. Bogor City Square is the best park in terms of air humidity control function and quite good in terms of wind barrier and noise reduction functions.
