Abstract

Kota Surabaya memiliki fluktuasi peningkatan suhu sejak tahun 1980 hingga 2014, dengan pola spasial terkonsentrasi dari utara ke selatan. yaitu pada kawasan pusat kota. Pada siang hari pada titik lokasi Plasa Tunjungan, Kawasan Pasar Turi dan Jl. Pahlawan dapat mencapai 41°C. jika dilihat dari Temperature Relative Humidity> 26 oC menciptakan lingkungan yang tidak nyaman. UHI dapat dilihat dari city form dan city function, city form yang meliputi geometri, penggunaan material, dan ruang terbuka hijau, sedangkan city function meliputi penggunaan energi, penggunaan air, dan polusi udara. Sebagai wilayah kawasan strategis ekonomi dan pusat kegiatan, penting untuk mengetahui upaya penanganan UHI di kawasan CBD Kota Surabaya yaitu UP.Tunjungan. Metode penelitian dilakukan dengan memetakan suhu permukaan di kawasan CBD Kota Surabaya (UP. Tunjungan) dengan TIRS (Citra Landsat 8), kedua menganaisis karakteristik city form dan city function pada kawasan CBD Kota Surabaya (UP. Tunjungan), ketiga menganalisis faktor-faktor yang mempengaruhi suhu permukaan dengan analisis regresi linier berganda, serta interpretasi hasil untuk menghasilkan konsep manajemen UHI. Rentang suhu permukaan UP. Tunjungan rata-rata berkisar antara 30.12 – 35.71oC. Suhu terpanas berada pada kawasan yang padat permukiman dan perdagangan dan jasa yang tidak terdapat RTH dan sungai. Keberadaan RTH mampu menurunkan suhu lokal 1,13-1,76oC, sedangkan daerah aliran sungai mampu menurunkan suhu lokal 0,88-1,720C. Keberadaan UHI disebabkan oleh nilai SVF (Sky View Factor), luasan sungai, ketinggian bangunan, emisi CO2 dari kegiatan permukiman, transportasi dan perdagangan dan jasa. Upaya konsep manajemen UP. Tunjungan dilakukan dengan menjadikan konsep POAC sebagai payung dalam mengurangi urban heat island. POAC terdiri dari proses perencanaan, pengorganisasian, pelaksanaan, dan pengawasan. Dalam tahapan perencanaan dilakukan melalui penetapan skyline di UP.Tunjungan, perencanaan pentahapan pembangunan angkutan massal cepat, pengembangan lahan compact pada penggunaan lahan mixed used secara vertikal dan penetapan harga tiket parkir pusat kota serta mengganti bus kota dengan electrical solar bus. Pengorganisasian dilakukan melalui pemetaan stakeholder, sosialisasi kegiatan rencana kota kepada seluruh stakeholder, melakukan dialog koordinasi multipemangku kepentingan, serta merumuskan program prioritas berbasiskan partisipatif masyarakat. Tahapan pelaksanaan dihasilkan berdasarkan kegiatan yang telah dilakukan Kota Surabaya namun butuh pengembangan terutama pada pusat kota. Tahapan pelaksanaan dilakukan dengan pengembangan urban farming berbasis organik, kampung green and clean, pengoptimalan fungsi sungai sebagai penurun suhu permukaan, serta menerapkan green energy dan green building pada setiap bangunan. Upaya pengawasan dilakukan melalui pemantauan secara berkala kualitas air dan udara pusat kota, penerapan insentif dan disinsentif investasi pembangunan dan teknologi yang ramah lingkungan, mensyaratkan bangunan green energy dan green building dalam mengeluarkan IMB, penetapan pajak progresif kepemilikan kendaraan bermotor, serta menetapkan jarak sempadan sungai minimal 3 meter dari tanggul terluar dan pengendalian alih fungsi di dalamnya. ============================================================================== Surabaya City has a fluctuating temperature increase from 1980 to 2014, with a concentrated spatial pattern from north to south, is the downtown area. in the daytime the location point Tunjungan Plaza, Pasar Turi and Jl. Pahlawan, can reach to 41°C. More than 26°C of Temperature Relative Humidity would create an uncomfortable environment. Urban Heat Island (UHI) can be seen by the city form and city function. City form is determined by the geometry, material usage, and open green space. While the city function can be seen from energy use, water use, and pollution of an area. As an economy strategic area and urban core activity, it is important to determine the cause of rising temperatures, for manage of UHI in the CBD area of Surabaya is UP.Tunjungan. The research’s methods are mapping the surface temperature of Surabaya’s CBD area (UP, Tunjungan) with TIRS (Landsat 8), analyzing the characteristics of city form and city function (of UP. Tunjungan), then analyzing factors affects the surface temperature by multiplying linear regression analysis, and interpretation of the results to produce a UHI management concept. The average allowance ranged between 30.12 - 35.71oC. Temperature in excess of 330C indicates the occurrence of UHI. The hottest temperatures are in the area of dense settlement and trade service. Green space may decrease the local temperature from 1,13-1,76oC, while rivers may decrease local temperature 0,88- 1,720C. UHI is caused by the SVF (sky view factor) value, the extent of the river, building height, CO2 emissions of settlement activities, transport and trade and services. Management concept UP. Tunjungan is done by making the concept POAC as principal to reduce UHI. POAC consists of the process of planning, organizing, implementing, and monitoring. planning management by setting skyline in UP.Tunjungan, phasing development plan of rapid mass transit, compact land development on land use mixed used vertically, set the price of parking tickets in downtown and replacing city buses with electric bus. Organizing management through mapping of stakeholders, socialization activities of the city plan to all stakeholders, coordination of multi-stakeholder dialogue, and formulate program priorities based on community participation. Stages of implementation generated by activities that have been performed Surabaya but need further development, especially in downtown UP. Tunjungan. Implementation management by process can be done through with development of organic urban farming, settlements green and clean, optimizing the function of the river as the lowering of the surface temperature, and implement green energy and green building.Controlling management by efforts conducted through regular monitoring water and air quality in downtown, incentives and disincentives of investment in development environmentally friendly and ecofriendly technology, requires the building of green energy and green building in releasing IMB (building permit), the implementation of a progressive tax vehicle ownership, and determine the distance river border minimal 3 meters from the outer dike and control over the function in it.
