Abstract

Perubahan iklim dan pemanasan global telah menyebabkan peningkatan suhu dan kelembapan di wilayah perkotaan, khususnya di daerah padat penduduk Unit Pengembangan (UP) VI Tunjungan, yaitu Kelurahan Embong Kaliasin, Kecamatan Genteng Kota Surabaya. Penelitian ini bertujuan untuk menganalisis kenyamanan termal indeks Universal Thermal Climate Index (UTCI) melalui pemodelan 3D perkotaan Level of Detail (LOD) 1 menggunakan data LiDAR dan orthofoto untuk menganalisis pengaruh profil bangunan. Data yang digunakan meliputi pengolahan data DSM dan DTM untuk menghasilkan nDSM (Normalized Digital Surface Model) sebagai ketinggian bangunan, serta orthofoto untuk digitasi. Pengolahan kota tiga dimensi pada ArcGIS Pro ini akan dilakukan uji validasi menggunakan pengukuran ketinggian bangunan dengan Total Station dengan perhitungan Root Mean Square Error (RMSE). Hasil RMSE validasi ketinggi bangunan adalah 0,25 meter. Hasil RMSE tersebut masuk dalam standar akurasi LOD 1. Simulasi kenyamanan termal UTCI dilakukan menggunakan software ENVI-met dengan parameter suhu udara, kelembapan, kecepatan angin, dan arah angin dari data Badan Meteorologi, Klimatologi, dan Geofisika. Untuk simulasi input database material pada ENVI-met tiap area tidak menggunakan material yang berbeda, sehingga material bangunan belum mendekati kondisi eksisting lingkungan profil bangunan. Hasil simulasi kenyamanan termal UTCI menghasilkan rata rata 39,42 (°C) sampai 43,10 (°C). Untuk hasil suhu udara yang mempengaruhi kenyamanan termal UTCI menghasilkan nilai rata-rata sebesar 33,45 (°C) sampai 36,14 (°C). Sedangkan untuk hasil simulasi kecepatan angin menghasilkan nilai rata-rata sebesar 2,20 (m/s) sampai 3,49 (m/s). Hasil kenyamanan termal tersebut menunjukkan bahwa kenyamanan termal di Kelurahan Embong Kaliasin merepresentasikan klasifikasi kenyamanan termal panas tinggi. Profil bangunan seperti orientasi massa bangunan, rasio H/W (tinggi bangunan terhadap jalan), sky view factor, luas dan bentuk bangunan, kepadatan bangunan, serta material memengaruhi kenyamanan termal ruang luar.

Climate change and global warming have caused an increase in temperature and humidity in urban areas, especially in the densely populated area of Development Unit (UP) VI Tunjungan, namely Embong Kaliasin sub-district, Genteng District, Surabaya City. This study aims to analyze the thermal comfort of the Universal Thermal Climate Index (UTCI) index through 3D urban modeling Level of Detail (LOD) 1 using LiDAR data and orthophotos to analyze the influence of building profiles. The data used include DSM and DTM data processing to produce nDSM (Normalized Digital Surface Model) as building height, as well as orthophotos for digitization. This three-dimensional city processing in ArcGIS Pro will be validated using building height measurements using Total Station with Root Mean Square Error (RMSE) calculations. The RMSE result of the building height validation is 0.25 meters. The RMSE result is included in the LOD 1 accuracy standard. The UTCI thermal comfort simulation was carried out using ENVI-met software with parameters of air temperature, humidity, wind speed, and wind direction from data from the Meteorology, Climatology, and Geophysics Agency. For the simulation of material database input in ENVI-met, each area does not use different materials, so the building materials have not approached the existing conditions of the building profile environment. The UTCI thermal comfort simulation results produce an average of 39.42 (°C) to 43.10 (°C). For the results of air temperature that affects thermal comfort, UTCI produces an average value of 33.45 (°C) to 36.14 (°C). Meanwhile, the results of the wind speed simulation produce an average value of 2.20 (m/s) to 3.49 (m/s). The thermal comfort results indicate that thermal comfort in Embong Kaliasin Village represents a high heat thermal comfort classification. Building profiles such as building mass orientation, H/W ratio (building height to road), sky view factor, building area and shape, building density, and materials affect the thermal comfort of outdoor spaces.
