Juananda, Bima and Dr. Ir. Abdul Wahid Hasyim, MSP. and Kartika Eka Sari, ST., MT. (2022) Evaluasi Kebutuhan Ruang Terbuka Hijau Berdasarkan Temperature Humidity Index di Kota Surabaya. Sarjana thesis, Universitas Brawijaya.
Abstract
Kota Surabaya diarahkan sebagai Pusat Kegiatan Nasional dan akan dikembangkan lagi sehingga memiliki skala pelayanan internasional (RTRW Kota Surabaya Tahun 2014-2034), sehingga terjadi perkembangan pembangunan yang diikuti dengan pertumbuhan penduduk dan laju perekonomian yang cepat menyebabkan bertambahnya luasan lahan terbangun dan dapat berdampak mengurangi luasan ruang terbuka hijau. Ketersediaan ruang terbuka hijau dapat mempengaruhi suhu dan kelembaban udara sehingga berpengaruh juga terhadap tingkat kenyamanan iklim mikro atau biasa disebut dengan Temperature Humidity Index (THI) (Zubair, 2017). THI sendiri merupakan tingkat kenyamanan termal pada suatu wilayah yang memiliki rentang kenyamanan sebesar 21⁰C-26⁰C (Emmanuel, 2005). Penelitian ini bertujuan untuk mengevaluasi terkait kebutuhan RTH di Kota Surabaya berdasatkan THI dengan menggunakan analisis regresi linear berganda sehingga didapatkan model untuk mengidealkan THI di Kota Surabaya. Adapun pendekatan yang dilakukan adalah dengan menggunakan pengideraan jauh memanfaatkan citra Landsat tahun 2020. Proses pengolahan data dengan melalui beberapa tahapan pengolahan NDVI, pengolahan klasifikasi tutupan lahan, pengolahan suhu permukaan, pengolahan THI dan menggunakan analisis regresi linear berganda. Setelah melalui tahapan tersebut ditemukan bahwa tutupan lahan berupa badan air, lahan terbangun serta vegetasi tinggi memiliki pengaruh terhadap THI. Model regresi yang didapatkan adalah Y = 27,275 – 28,756X5 – 14,030X1 + 1,642X3. Dengan catatan Y (THI rata-rata), X1 (badan air), X3 (lahan terbangun) dan X5 (vegetasi tinggi). Model tersebut memiliki nilai koefisien determinasi sebesar 82,0%. Setelah model regresi didapatkan, maka dapat diketahui kebutuhan RTH (yang berupa vegetasi tinggi) untuk mengidealkan nilai THI di Kota Surabaya sehingga menjadi nyaman.
English Abstract
The city of Surabaya is directed as a National Activity Center and will be developed again so that it has an international service scale (RTRW of Surabaya City 2014 -2034), so that development developments are followed by population growth and a fast economic rate causing an increase in the area of built-up land and can have an impact on reducing the area. green open space. The availability of green open space can affect the temperature and humidity of the air so that it also affects the comfort level of the microclimate or commonly referred to as the Temperature Humidity Index (THI) (Zubair, 2017). The meaning of THI itself is thermal comfort in an area that has a comfort range of 21⁰C-26⁰C (Emmanuel, 2005). This study aims to evaluate the need for green open space in the city of Surabaya based on THI by using multiple linear regression analysis in order to obtain a model to idealize THI in the city of Surabaya. The approach taken is to use remote sensing utilizing Landsat imagery in 2020. The data processing process goes through several stages of NDVI processing, land cover classification processing, surface temperature processing, THI processing and using multiple linear regression analysis. After going through these stages, it was found that land cover in the form of water bodies, built-up land and high vegetation had an influence on THI. The regression model obtained is Y = 27,275 – 28,756X5 – 14,030X1 + 1,642X3. With a record Y (average THI), X1 (body of water), X3 (built-up land) and X5 (high density vegetation). The model has a coefficient of determination of 82.0%. After the regression model is obtained, it can be seen that the need for green open space (in the form of high vegetation) to idealize the THI value in the city of Surabaya is 22.42% of the total area of the city of Surabaya and is divided into all sub-districts.
