Ameliorasi Iklim melalui Revegetasi Lahan Star Energy Geothermal, Sukabumi, Jawa Barat

Abstract

Program revegetasi lahan SEGS ditujukan untuk memperbaiki atau memulihkan kondisi vegetasi yang terdegradasi. Program penanaman atau pemeliharaan ini dilakukan melalui kerjasama dengan TNGHS. Penelitian ini bertujuan mengkaji ameliorasi iklim dari program revegetasi dengan indikator perubahan suhu permukaan serta kerapatan tajuk. Penelitian ini dilaksanakan pada Februari-April 2024. Alat dan bahan yang digunakan meliputi Avenza Maps, GPS, peta lokasi, Microsoft Office (Word dan Excel), Google Earth, ArcGIS 10.8, ERDAS Imagine 2015, dan citra Satelit Landsat Sukabumi. Analisis data dilakukan dengan identifikasi tutupan lahan, analisis suhu permukaan, analisis FCD, dan analisis hubungan kerapatan tajuk dengan suhu permukaan. Hasil penelitian menunjukkan bahwa terdapat tren penurunan suhu permukaan dan peningkatan kerapatan tajuk dalam waktu 10 tahun. Selain itu, terdapat hubungan terbalik antara kerapatan tajuk dengan suhu permukaan dengan korelasi sebesar -65,76%. Hal tersebut menandakan adanya keberhasilan revegetasi pada lokasi penelitian yang ditunjukkan adanya proses ameliorasi iklim dan peningkatan kanopi hutan.

The SEGS land revegetation program is aimed at improving or restoring the condition of degraded vegetation. This planting or maintenance program is carried out in collaboration with TNGHS. This research aims to examine climate amelioration from the revegetation program with indicators of changes in surface temperature and canopy density. This research was carried out in February-April 2024. The tools and materials used included Avenza Maps, GPS, location maps, Microsoft Office (Word and Excel), Google Earth, ArcGIS 10.8, ERDAS Imagine 2015, and Landsat Sukabumi Satellite imagery. Data analysis was carried out by identifying land cover, surface temperature analysis, FCD analysis, and analyzing the relationship between canopy density and surface temperature. The research results show that there is a trend of decreasing surface temperature and increasing canopy density within 10 years. In addition, there is an inverse relationship between canopy density and surface temperature with a correlation of -65.76%. This indicates the success of revegetation at the research location, which is indicated by a process of climate amelioration and an increase in the forest canopy.
