Mining operations disrupt the equilibrium of terrestrial ecosystems, leading to a decline in soil fertility and overall environmental quality. The adverse effects of such activities can severely impact forest ecosystems, resulting in disturbances to physical, chemical, and biological conditions. Consequently, initiatives aimed at restoring soil health to its pre-mining state are essential, often involving revegetation efforts. The cultivation of red jabon trees in nutrient-deficient and less fertile soils necessitates the incorporation of organic matter to enhance soil quality, typically achieved through the application of compost. This study aimed to evaluate the effects and optimal ratios of compost mixed with ex-gold mining soil on the growth of red jabon seedlings. The experimental design included four treatment groups and five replications, yielding a total of 20 experimental units. The treatments for compost application were as follows: D1 = control (no compost), D2 = 10% compost 90% ex-gold mining soil, D3 = 30% compost 70% ex-gold mining soil, and D4 = 50% compost 50% ex-gold mining soil. The parameters observed included survival rate, height growth, diameter growth, dry weight of the plants, and root-to-crown ratio. The findings indicated that the application of compost significantly influenced the growth of red jabon seedlings. Notably, treatment D4 (50% compost 50% ex-gold mining soil) yielded the most favorable results, achieving a survival rate of 100%, a height increase of 16.56 cm, a diameter increase of 2.21 mm, a dry weight of 40.73 g, and a root-to-crown ratio of 4.84.

Conclusion

The provision of compost fertilizer in the planting media of former gold mines significantly impacts the growth of Anthocephalus macrophyllus seedlings.The treatment with a composition of 50% compost and 50% former gold mine soil (D4) was identified as the optimal treatment for the growth of red jabon seedlings.This resulted in a 100% survival rate, a height increase of 16.56 cm, a diameter increase of 2.21 mm, a dry plant weight of 40.73 g, and a root-crown ratio of 4.

Future Research

Penelitian lebih lanjut perlu dilakukan untuk mengkaji pengaruh berbagai jenis kompos, seperti kompos dari limbah perkotaan atau limbah pertanian, terhadap pertumbuhan jabon merah di lahan bekas tambang emas. Hal ini penting untuk menemukan sumber kompos yang lebih berkelanjutan dan ekonomis. Selain itu, penelitian perlu difokuskan pada interaksi antara kompos dengan mikroorganisme tanah, khususnya mikoriza, untuk meningkatkan efisiensi penyerapan nutrisi oleh tanaman. Studi mendalam mengenai mekanisme adaptasi jabon merah terhadap kondisi tanah bekas tambang, termasuk toleransi terhadap logam berat, juga sangat diperlukan. Penelitian ini dapat dilakukan dengan menganalisis ekspresi gen yang terlibat dalam detoksifikasi logam berat atau dengan mengidentifikasi varietas jabon merah yang memiliki tingkat toleransi lebih tinggi. Terakhir, perlu dilakukan penelitian mengenai efektivitas kombinasi antara aplikasi kompos dengan teknik bioremediasi lainnya, seperti fitoremediasi, untuk mempercepat proses pemulihan lahan bekas tambang emas dan meningkatkan keanekaragaman hayati.
