Abstract

Reclamation of former coal mining land is an obligation for mining companies to restore environmental conditions that have been disturbed due to mining activities. PT Bara Energi Lestari has carried reclamation and revegetation efforts in its former mining areas. The use of satellite imagery or remote sensing plays an important role in evaluating reclamation and revegetation activities. Satellite imagery greatly facilitates the evaluation process, particularly in analyzing land cover, improving time efficiency, and providing diverse visual data. Therefore, this study aims to evaluate the progress of revegetation in the reclamation areas of PT Bara Energi Lestari during the third reclamation period (2020–2024) and to assess the success of revegetation efforts through the analysis of the Normalized Difference Vegetation Index (NDVI). The study utilized NDVI data derived from Sentinel-2 imagery acquired from 2020 to 2024, which were spatially analyzed to examine changes in revegetation levels within the reclamation areas over the study period. The results of the analysis show that the revegetation efforts carried out in the reclamation areas of PT Bara Energi Lestari during the 2020–2024 period, which initially planned a reclamation area of 46.31 hectares, were ultimately realized on a reduced area of 43.91 hectares. Based on the analysis, the reclamation area from 2020 showed a vegetation cover of 98%, the 2021 area had 99%, the 2022 area had 89%, while the 2023 area dropped to 16%, and the 2024 area had only 9% vegetation cover.

Abstract

Persoalan bencana gempa bumi sangat erat kaitannya dengan sisi kehidupan masyarakat baik bersifat individual maupun kelompok. Pemahaman akan potensi terjadinya bencana gempa bumi sangat penting di kehidupan sehari-hari. Dalam menangani bencana gempa bumi perlu dilakukan pendekatan secara menyeluruh dengan melibatkan semua elemen masyarakat. Hal ini bertujuan agar terbangun kesadaran akan potensi terjadinya bencana gempabumi. Pengabdian ini telah dilakukan dengan melibatkan salah satu elemen masyarakat yaitu pelajar di Sekolah Menengah Pertama (SMP) Negeri 2 Darul Imarah, Kabupaten Aceh Besar, Provinsi Aceh. Sosialisasi tentang bahaya dan dampak terjadinya bencana gempa bumi sangatlah penting mengingat bencana ini dapat terjadi kapan saja dan dimana saja. Kegiatan pengabdian masyarakat ini bertujuan untuk dapat memberikan informasi tentang penyebab terjadinya gempa bumi dan faktor bencana yang muncul akibat gempa bumi tersebut. Kegiatan sosialisasi ini dilakukan menggunakan metode Participatory Rural Appraisal (PRA) yang dilakukan dengan cara mengajak para peserta kegiatan untuk berpartisipasi dalam proses pengembangan sebuah kegiatan. Setelah mengikuti kegiatan ini, para pelajar diharapkan dapat berhati-hati apabila bencana gempa bumi tersebut muncul serta dapat melakukan tindakan mitigasi akibat bencana yang muncul dari gempa bumi.
