Abstract
Penelitian ini dilatarbelakangi karena adanya perubahan iklim yang terjadi di Kota Semarang sehingga perlu adanya model infrastruktur hijau dalam upaya mewujudkan ketahanan di Kota Semarang, yang dapat diterapkan pada pengaruh keberadaan taman di perkotaan melalui kontribusi ekosistem yang ada didalamnya. Salah satu elemen pendukung karakteristik taman kota yang dapat dikaji melalui kerapatan vegetasi tumbuhan pada taman. Untuk mencegah adanya dampak perubahan iklim dapat dikaji melalui tingkat kerapatan vegetasi yang menjadi salah satu elemen pendukung pada karakteristik suatu taman kota dengan pemanfaatan citra Landsat. Evaluasi respon infrastruktur hijau taman kota melalui kerapatan vegetasi yang menjadi ekosistem didalamnya menjadi sangat penting untuk dianalisis karena merupakan tolak ukur dalam penentuan kebijakan dalam melakukan pemeliharaan dan pengelolaan RTH terkait pentingnya komposisi jenis vegetasi yang mengandung klorofil tinggi dan dapat mengurangi pencemaran udara dan meningkatkan kenyamanan lingkungan melalui penilaian suhu permukaan di lingkungan sekitar. Tujuan penelitian ini untuk menganalisis karakteristik taman kota melalui indeks vegetasi dalam upaya mewujudkan ketahanan Kota Semarang. Metode kuantitatif dengan menggunakan data sekunder untuk memperoleh (1) rekaman data citra Landsat 8 untuk analisis indeks vegetasi NDVI (Normalized Difference Vegetation Index) terkait variabel indeks vegetasi & persentase tutupan hijau (2) analisis land surface temperature (LST) terkait tingkat suhu permukaan tanah di Kota Semarang,(3) analisis indeks kenyamanan/ temperature humidty indeks (THI) untuk variabel pendekatan tingkat kenyamanan di lingkungan sekitar, dan (3) observasi & dokumentasi lapangan untuk uji validasi & verfikasi hasil pemetaan. Analisis yang digunakan dalam penelitian ini yaitu analisis deskriptif, analisis indeks vegetasi NDVI (Normalized Difference Vegetation Index), analisis Land Surface Temperatur (LST), analisis Temperature Humidity Index dan analisis regresi linear berganda. Hasil penelitian menunjukkan taman pasif memiliki hubungan indeks vegetasi dan indeks kenyamanan yang signifikan selama 2 (dua) periode musim dibandingkan taman aktif dengan pengaruh sebesar 67,2% di periode akhir musim penghujan dan pengaruh sebesar 74,7% diperiode akhir musim kemarau. Kata kunci:taman kota, infrastruktur hijau, indeks vegetasi, suhu permukaan The background of this study is because of the climate change that occurred in Semarang City so that there needs to be a green infrastructure model in an effort to realize resilience in Semaran City, that can be applied to the influence of the existence of the park in urban areas through the contribution of the ecosystem is inside. One of the supporting elements of the characteristics of urban parks that can be assessed through vegetation density in the garden. To avoid the impact of changes in levels can be reviewed through the level of vegetation density which is one of the supporting elements in the characteristics of urban parks using Landsat imagery. Evaluation of the green infrastructure of urban parks through vegetation density which is an ecosystem in it becomes very important to be analyzed because it is a benchmark in the framework in planning and managing green open space related to the composition of vegetation types that contain high chlorophyll and can be used for air pollution and increased safety Estimated Surfaces in the Neighborhood. The purpose of this study is to analyze the characteristics of urban parks through the vegetation index in an effort to realize the resilience of Semarang City. Quantitative methods using secondary data to be obtained (1) recording Landsat 8 image data for NDVI vegetation index analysis (Normalized Difference Vegetation Index) related to vegetation index variables & green cover percentage (2) land surface temperature analysis (LST) in Semarang City, (3) analysis of the comfort index / damp temperature index (THI) for variables of comfort level in the surrounding environment, and (3) observation & field tracking for validation test & verification of search results. The analysis used in this study is descriptive analysis, analysis of NDVI vegetation index (Normalized Difference Vegetation Index), analysis of Soil Surface Temperature (LST), Temperature Humidity Index analysis and multiple linear regression analysis. The results showed that the passive garden of the index of vegetation relations and comfort index was significant for 2 (two) season periods comparing the active garden with the influence of 67.2% in the late rainy season and increasing by 74.7% in the late dry season.
