Istiqomah, Rani Nur (2019) Pengaruh Tutupan Lahan Terhadap Kenyamanan Termal Iklim Mikro Kota Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Dampak perkembangan fisik kota akan berpengaruh pada peningkatan suhu bumi (IPCC, 2007). Suhu merupakan salah satu unsur Iklim mikro. Apabila terjadi perubahan pada salah satu unsur iklim mikro, akan mempengaruhi kenyamanan termal. Kota Malang mengalami peningkatan suhu permukaan sebesar 0,04 oC setiap tahunnya sedangkan, jumlah tutupan lahan tidak terbangun berupa RTH mengalami penurunan 2,8%. Perubahan ini akan berdampak pada kenyamanan termal yang dihitung dengan Temperature Hummidity Index/ THI (Effendy 2007). Berdasarkan persebaran THI di Kota Malang, pola THI semakin menjauhi pusat kota semakin nyaman. Hasil analisis THI menunjukan bahwa, Kelurahan Sukoharjo, Kasin, Tulusrejo, Ciptomulyo, dan Kotalama dinyatakan tidak nyaman karena memiliki nilai THI >26. Kondisi ini terjadi karena semakin ke pusat kota, jumlah tutupan lahan tidak terbangun semakin tinggi. Berdasarkan analisis Regresi linier berganda didapatkan pengaruh luas tutupan lahan dengan THI di masing-masing kecamatan. Adapun variabel yang berpengaruh positif pada peningkatan THI disetiap kecamatan dipengaruhi oleh luas tutupan lahan terbangun. Sedangkan nilai THI berpengaruh negatif pada tutupan lahan badan air dan tutupan lahan vegetasi. Adapun sala satu model pengaruh tutupan lahan terhadap kenyamanan termal iklim mikro di Kecamatan Klojen yakni, Y = 21,319+(0,049).X1+(-0,055)X2+(-0,306). X3+ (-0,251). X4. Setiap terjadi peningkatan pada luasan X1 (lahan terbangun), akan terjadi peningkatan nilai THI sebesar 0,049.
English Abstract
The impact of city’s physical development will affected on rising earth temperature (IPCC, 2007). Air temperature is one of the elements from microclimate, if this changes will affect to the Micro Climate Thermal Comfort. Malang has an experienced in increase surface temperature of 0,04 oC every years while, the amount of coverage in unbuilt land in the type of RTH decreased by 2,8%. This change will have an impact on thermal comfort calculated by the Temperature Humidity Index / THI (Effendy,2007). Based on the distribution of THI, Malang City has an increasingly distant pattern towards the city center, where Kelurahan Sukoharjo, Kasin, Tulusrejo, Ciptomulyo, and Kotalama are declared uncomfortable, because they have THI values> 26. This condition occurs because, the amount of land cover in center of city is getting higher. Based on the analysis of Multiple linear Regression Alghifari (2009), the effect of land cover area with THI in each district was found, Where the variables have a positive effect on the increase in THI in each sub-district affected by the extent of built up area. While THI value is negatively related to land cover of water bodies and vegetation land cover. One models of land cover influance on micro thermal comfort in Klojen district is, Y = 21,319+ (0,049) .X1 + (- 0,055) X2 + (- 0,306). X3 + (-0.251). X4. Every increase in the area of X1 (land built), there will be an increase in the value of THI of 0.049 in Klojen district.
