      Abstract
      Akibat adanya gangguan, ekosistem akan merespon dengan melakukan pemulihan vegetasinya. Secara teori, ekosistem yang asli dapat berperan sebagai sumber biji bagi tempat-tempat yang sudah mengalami perubahan ekosistem. Penelitian ini bertujuan menganalisis komposisi dan keragaman jenis dari soil seed bank di HPGW, menganalisis pengaruh kedalaman tanah terhadap soil seed bank, serta menganalisis perubahan komposisi jenis pada regenerasi tumbuhan baru setelah adanya gangguan. Penelitian ini dilaksanakan pada bulan November 2024 – Maret 2025. Tahapan pada penelitian ini meliputi proses analisis vegetasi, pengukuran unsur klimatis dan edafis lokasi penelitian, uji perkecambahan, serta pengamatan perubahan komposisi vegetasi. Hasil penelitian ini menunjukkan soil seed bank dari kedua zona menumbuhkan jenis-jenis herba yang beragam. Perbedaan kedalaman tanah dalam pengambilan sampel soil seed bank terbukti tidak menunjukkan perbedaan yang signifikan, dilihat dari hasil uji Mann-Whitney pada kedua zona yang memiliki p-value > 0,05. Kedua zona mengalami perubahan vegetasi hasil regenerasi pasca gangguan.
       
      As a result of disturbance, the ecosystem will respond by restoring its vegetation. In theory, native ecosystems can act as a source of seeds for places that have experienced ecosystem changes. This research aims to analyze the composition and diversity of soil seed bank species in GWUF, analyze the effect of soil depth on soil seed banks, and analyze changes in species composition in the regeneration of new plants after disturbances. This research was conducted in November 2024 - March 2025. The stages in this research include the process of vegetation analysis, measurement of climatic and edaphic elements of the research location, germination tests, and observations of changes in vegetation composition. The results of this research show that soil seed banks from both zones grow various types of herbs. Differences in soil depth in soil seed bank sampling were shown to show no significant differences, as seen from the results of the Mann-Whitney test in both zones which had a p-value > 0.05. Both zones experienced changes in vegetation resulting from post-disturbance regeneration.
