Abstract: Kegiatan sektor panas bumi yang menggunakan bahan bakar fosil menghasilkan CO2 yang dapat menimbulkan efek rumah kaca dan pemanasan global. Pelestarian lingkungan pasca tambang telah dilakukan oleh Star Energy Geothermal Salak dengan cara melakukan program revegetasi lahan. Penelitian ini bertujuan untuk mengkaji hubungan antara kerapatan tajuk dan iklim mikro dengan indikator suhu udara, kelembapan udara, dan intensitas cahaya matahari pada lahan revegetasi. Analisis data dilakukan dengan pengukuran suhu dan kelembapan udara, pengukuran intensitas cahaya matahari, pengambilan foto Leaf Area Index (LAI), dan metode analisis regresi linear berganda. Hasil penelitian menunjukkan bahwa terdapat hubungan antara suhu udara dan kelembapan udara sebagai variabel terikat dengan intensitas cahaya matahari dan LAI sebagai variabel bebas yang dapat dilihat dari hasil analisis regresi linear berganda. Model regresi dapat menjelaskan sebesar 43% perubahan pada variabel suhu udara dan sebesar 40% perubahan pada variabel kelembapan udara dapat dijelaskan oleh variabel independen dalam model. Selain itu, hasil akhir menunjukkan tajuk pohon yang rapat dapat memperbaiki kondisi iklim mikro di Star Energy Geothermal Salak.
Geothermal sector activities that use fossil fuels produce CO2 which can cause the greenhouse effect and global warming. Environmental preservation has been carried out by Star Energy Geothermal Salak by conducting a land revegetation program. This study aims to assess the relationship between canopy density and microclimate with indicators of air temperature, air humidity, and sunlight intensity on revegetated land. Data analysis was carried out by measuring air temperature and humidity, measuring sunlight intensity, taking photos of Leaf Area Index, and multiple linear regression analysis methods. The results showed that there is a relationship between air temperature and air humidity as the dependent variable with sunlight intensity and LAI as independent variables which can be seen from the results of multiple linear regression analysis. The regression model can explain 43% of changes in the air temperature variable and 40% of changes in the air humidity variable can be explained by the independent variables in the model.In addition, the final results show that dense tree crowns can improve microclimateconditions at Star Energy Geothermal Salak.
