Abstract

Fenomena urban heat island (UHI) di kawasan perkotaan mendorong perlunya pengembangan ruang terbuka hijau (RTH) sebagai strategi adaptasi. Penelitian ini bertujuan merumuskan arahan pengembangan RTH yang adaptif untuk mengurangi UHI di Kecamatan Tegalsari, Kota Surabaya. Tahapan penelitian meliputi: (1) penilaian kinerja RTH eksisting dalam menurunkan suhu, (2) identifikasi faktor-faktor yang memengaruhi efektivitas pendinginan RTH, dan (3) perumusan arahan pengembangan RTH. Analisis kinerja menunjukkan RTH dengan pohon bertajuk padat dan lebat mampu menurunkan suhu rata-rata 0.44–0.46 ℃, RTH semak/rumput 0.08 ℃, sedangkan cool pavement hanya 0.01 ℃. Lima variabel eksternal berpengaruh signifikan meliputi: luas RTH, kerapatan vegetasi, proporsi area hijau sekitar, jarak tanam pohon, dan dominasi jenis vegetasi. Luas, kerapatan, dan dominasi pohon berkorelasi positif dengan pengurangan suhu. Sementara, proporsi hijau sekitar dan jarak tanam pohon berkorelasi negatif . Dari temuan ini,direkomendasikan arahan peningkatan luas dan kerapatan RTH, optimalisasi jarak tanam (1–1.5 m), serta penjadwalan pemeliharaan rutin. Selain itu, arahan spesifik disusun untuk lima tipe kawasan RTH (jalur hijau, taman aktif, taman pasif, lapangan, lahan terbuka) dengan integrasi peran DKRTH, insentif partisipasi masyarakat, dan kemitraan swasta. Implementasi arahan ini diharapkan mampu memaksimalkan fungsi ekologis RTH dan menurunkan intensitas UHI di Tegalsari.

The urban heat island (UHI) phenomenon in urban areas necessitates the development of green open spaces (GOS) as an adaptation strategy. This study aims to formulate adaptive GOS development guidelines to mitigate UHI in Tegalsari District, Surabaya City. Research stages include: (1) assessment of existing GOS performance in reducing temperature, (2) identification of factors affecting GOS cooling effectiveness, and (3) formulation of GOS development guidelines. Performance analysis shows that GOS dominated by dense, leaved trees can lower temperatures by an average of 0.44–0.46 °C, shrub/grass GOS by 0.08 °C, while cool pavement only by 0.01 °C. Five external variables significantly influence cooling performance: GOS area, vegetation density, proportion of surrounding green area, tree planting distance, and species dominance. Area, density, and tree dominance correlate positively with temperature reduction, whereas surrounding green proportion and planting distance correlate negatively. Based on these findings, recommendations include increasing GOS area and density, optimizing planting distance (1–1.5 m), and scheduling routine maintenance. Additionally, specific guidelines are developed for five GOS types (green corridors, active parks, passive parks, sports fields, open plots), integrating the role of the Surabaya GOS Agency (DKRTH), community participation incentives, and private-sector partnerships. Implementation of these guidelines is expected to maximize the ecological function of GOS and reduce UHI intensity in Tegalsari.
