Judul: Landscape Services Management of Water Resource and Thermal Comfort of City Park in Jakarta
Abstrak: Jakarta terus mengalami peningkatan kepadatan kota yang menyebabkan Ruang Terbuka Hijau (RTH) berkurang. Dampak yang terjadi adalah penurunan kualitas lanskap dan kenyamanan hidup karena adanya keterbatasan resapan air dan peningkatan suhu. Hal tersebut dibuktikan oleh Indeks Kualitas Lingkungan Hidup Jakarta 2022 yang berada pada kategori sedang. Taman kota mampu memberikan kontribusi yang signifikan sebagai penyedia jasa lanskap dalam menjaga keseimbangan siklus air dan mengatur iklim mikro. Penelitian ini bertujuan menganalisis jasa lanskap pengaturan tata air dan kenyamanan termal pada Taman Bambu, Taman Cattleya dan Taman Langsat, lalu menyusun rekomendasi pengelolaan lanskapnya. Perangkat i-Tree Eco digunakan untuk analisis jasa lanskap tata air menggunakan plot sampel. Temperature Humidity Index (THI) dilakukan untuk mengetahui kategori kenyamanan melalui pengukuran suhu dan kelembapan. Penyusunan rekomendasi strategi pengelolaan jasa lanskap dilakukan dengan analisis Strengths, Weaknesses, Opportunities, and Threats (SWOT). Hasil analisis i-Tree Eco menunjukkan pohon di ketiga taman kota mampu mengurangi limpasan 51,28 m³/tahun dengan nilai yang diperkirakan Rp1.944.573,61. Hasil analisis THI menunjukkan Taman Bambu memiliki THI 30, Taman Cattleya memiliki THI 30,4, dan Taman Langsat memiliki THI 30,2, ketiganya menunjukkan kategori kenyamanan yang tidak nyaman. Berdasarkan hasil analisis SWOT, ketiga taman kota berada pada Kuadran V, yakni pengelolaanya harus disusun berdasarkan hold and maintain strategy., Jakarta continues to experience increasing urban density, leading to a reduction in Green Open Spaces (GOS). This has decreased landscape quality and living comfort due to limited water infiltration and rising temperatures, evidenced by Jakarta's 2022 Environmental Quality Index, which is categorized as moderate. City parks play a significant role in provisioning landscape services by maintaining water cycles and regulating microclimates. This study aims to analyze the landscape services related to water resource and thermal comfort in Taman Bambu, Taman Cattleya, and Taman Langsat, and formulate recommendations for its landscape management. The i-Tree Eco was used to analyze water resource service using sample plots. The Temperature Humidity Index (THI) was used to determine the comfort category through temperature and humidity measurements. Recommendations for landscape management strategies were formulated using Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis. The i-Tree Eco analysis results show that trees in the three city parks can reduce runoff by 51,28 m³/year, with an estimated value of IDR 1.944.573,61. The THI analysis results show that Taman Bambu has a THI of 30, Taman Cattleya has a THI of 30,4, and Taman Langsat has a THI of 30,2, all indicating an uncomfortable category. Based on the SWOT analysis results, the three city parks are in Quadrant V, suggesting that their management should be developed based on a hold and maintain strategy.
