Abstract
Urbanisasi yang pesat dan perubahan iklim telah memperkuat efek urban heat island di kota-kota Indonesia, meningkatkan tekanan panas pada level pejalan kaki di pusat-pusat kota tropis yang padat. Mean radiant temperature (MRT) merupakan determinan utama kenyamanan termal luar ruang, namun bukti berbasis skenario desain yang mengkuantifikasi efek pendinginan berbasis vegetasi masih terbatas untuk konteks Indonesia. Penelitian ini memodelkan kondisi MRT baseline Kecamatan Genteng, sebuah hotspot UHI yang persisten di pusat Kota Surabaya, dan mengevaluasi kinerja pendinginan dari skenario optimasi kanopi pohon jalan yang sesuai dengan regulasi. MRT baseline disimulasikan menggunakan SOLWEIG dalam kerangka kerja UMEP-QGIS, dengan forcing data meteorologi ERA5-Land untuk hari cerah yang representatif, dan dibandingkan dengan sepuluh titik hasil pengukuran lapangan di berbagai sub-distrik Genteng; sembilan dari sepuluh titik berada dalam rentang kesepakatan ±5°C yang dapat diterima. Skenario kanopi pohon kemudian dirancang mengikuti standar pohon jalan Indonesia (Permen PU No. 05/PRT/M/2012), menambahkan 550.787 m² (55,08 ha) kanopi baru bersih sekitar 12,5% dari luas kecamatan dan dievaluasi ulang menggunakan SOLWEIG. Skenario ini menurunkan rata-rata MRT pada jam puncak (13:00) sebesar 7,29°C (12,1%) dan rata-rata MRT pada jendela waktu siang hari (07:00–17:00) sebesar 5,85°C (11,7%), sekaligus memangkas durasi harian paparan panas ekstrem (MRT > 55°C) dari 5,64 menjadi 4,01 jam (~29%). Pendinginan lokal di dalam zona penanaman melampaui 22°C. Temuan ini menunjukkan bahwa strategi pohon jalan yang sesuai regulasi, yang dapat diimplementasikan dalam ruang milik jalan (rumija) yang ada, menawarkan jalur praktis untuk menurunkan mean radiant temperature pada level pejalan kaki di distrik CBD tropis yang padat.

Rapid urbanization and climate change have intensified urban heat island effects in Indonesian cities, elevating pedestrian-level heat stress in dense tropical urban cores. Mean radiant temperature (MRT) is a key determinant of outdoor thermal comfort, yet design-scenario evidence quantifying vegetation-based cooling remains limited for Indonesian contexts. This research models the baseline MRT condition of Kecamatan Genteng, a persistent UHI hotspot in central Surabaya, and evaluates the cooling performance of a regulation-compliant street tree canopy optimization scenario. Baseline MRT was simulated using SOLWEIG within the UMEP-QGIS framework, forced with ERA5-Land meteorological data for a representative clear-sky day, and compared against ten field-measured points across Genteng's sub-districts; nine of ten fell within the accepted ±5°C agreement band. A tree canopy scenario was then designed following Indonesian street-tree standards (Permen PU No. 05/PRT/M/2012), adding 550,787 m² (55.08 ha) of net new canopy approximately 12.5% of the district and re-evaluated in SOLWEIG. The scenario reduced peak-hour (13:00) mean MRT by 7.29°C (12.1%) and daytime-window (07:00-17:00) mean MRT by 5.85°C (11.7%), while cutting the daily duration of severe heat exposure (MRT > 55°C) from 5.64 to 4.01 hours (~29%). Localized cooling within planting zones exceeded 22°C. These findings demonstrate that a regulation-compliant street-tree strategy, implementable within existing road right-of-way, offers a practical pathway to reducing pedestrian-level mean radiant temperature in dense tropical CBD districts.
