N2  - Kegiatan penambangan emas berdampak dalam menurunkan kesuburan
tanah. Hal ini menyebabkan lahan pascatambang sulit ditumbuhi tanaman karena
kurangnya kandungan unsur hara hingga kematian pada tanaman. Identifikasi FMA
lokal sangat penting dalam mempercepat proses keberhasilan revegetasi lahan
pascatambang. Penelitian ini bertujuan untuk mendapatkan sebaran, frekuensi dan
keragaman jenis FMA pada rhizosfer areal revegetasi lahan pascatambang emas PT
Natarang Mining dan menganalisis perbedaan keragaman jenis FMA pada dua
lokasi dan umur penanaman yang berbeda. Pengambilan sampel tanah
menggunakan teknik purposive sampling secara non proporsional dengan plot
berukuran 20m x 20m yang ditentukan pada sebaran vegetasi yang tumbuh di
lokasi. Lokasi pengambilan pengambilan sampel tanah ditentukan pada lahan
revegetasi tahun 2018 (Site-1) dan 2015 (Site-2). Spora FMA diperoleh
menggunakan metode saring basah. Sifat kimia tanah dengan parameter pH, N total,
P-tersedia, dan C-Organik dianalisis di laboratorium. Data yang diperoleh dianalisis
menggunakan analisis deskriptif.
Hasil penelitian menunjukkan bahwa terdapat 3 genus yang ditemukan, yaitu
Acaulospora sp (5 tipe spora), Gigaspora sp (8 tipe spora), dan Glomus sp (6 tipe
spora). Jumlah sebaran spora FMA pada kedua lokasi memiliki sebaran yang
bervariasi. Pada site-1 ditemukan 314 spora/250 gr tanah dengan 17 tipe spora,
sedangkan pada site-2 ditemukan sebanyak 257 spora/250 gr tanah dengan 12 tipe
spora. Jenis spora FMA yang paling banyak pada site-1 adalah genus Acaulospora
sp dengan kelimpahan relatif 49,04% dan frekuensi relatif 37,50%. Pada site-2 jenis
spora FMA yang paling banyak adalah genus Glomus sp dengan kelimpahan relatif
87,16% dan frekuensi relatif 37,50%. Keanekaragaman spora FMA pada kedua
lokasi tergolong sedang. Kondisi sifat kimia tanah tampaknya berpengaruh
terhadap jumlah dan tipe spora FMA yang ditemukan pada lokasi penelitian.

Gold mining activities have an impact on reducing soil fertility. Because the
post-mining land to be difficult growing cause of the lack of nutrients and the death
of the plant. Identification of local AMF is very important in accelerating the
successful process of post-mining land revegetation. This study aims to obtain the

distribution, frequency and diversity of AMF species in the rhizosphere of the post-
gold mining revegetation area of PT Natarang Mining and to analyze the differences

in the diversity of AMF species at two locations and at different planting ages. Soil
samples were taken using a non-proportional purposive sampling technique with a
plot measuring 20 m x 20 m determined on the distribution of vegetation growing
in the location. Soil sampling locations on revegetation land in 2018 (Site-1) and
2015 (Site-2). AMF spores were obtained using the wet filter method. Soil chemical
properties with parameters of pH, total N, available P, and C-Organic were analyzed
in the laboratory. The data obtained were analyzed using descriptive analysis.
The results showed that there were 3 genera found, namely Acaulospora sp
(5 spore types), Gigaspora sp (8 spore types), and Glomus sp (6 spore types). The
distribution of AMF spores at both locations varied. At site-1 found 314 spores/250
g of soil with 17 types of spores, while at site-2 found as many as 257 spores/250 g
of soil with 12 types of spores. The most abundant type of AMF spores at site-1
was the genus Acaulospora sp with a relative abundance of 49.04% and a relative
frequency of 37.50%. At site-2 the most abundant AMF spores were the genus
Glomus sp with a relative abundance of 87.16% and a relative frequency of 37.50%.
The diversity of AMF spores at both locations was moderate. The condition of the
chemical properties of the soil affected the number and type of AMF spores found
at the study site.
