KAJIAN UNSUR HARA P, K, DAN S PADA TANAH TERDAMPAK ERUPSI
GUNUNG SINABUNG YANG DITUMBUHI JAGUNG DI KECAMATAN
NAMAN TERAN KABUPATEN KARO

ABSTRAK
Ketersediaan unsur hara P,K, dan S memiliki peran penting untuk produktivitas
tanaman jagung. Erupsi Gunung Sinabung berpengaruh menurunkan ketersediaan
unsur hara pada tanah khususnya P, K dan S. Penelitian ini bertujuan untuk
mengetahui harkat unsur hara P, K, dan S pada tanah terdampak erupsi Gunung
Sinabung yang ditumbuhi jagung di kecamatan Naman Teran Kabupaten Karo,
Sumatra Utara.Penelitian ini menggunakan metode survey dengan 4 titik
pengambilan sampel. Tanah tidak terkena dampak erupsi (A0), tanah terdampak
erupsi jarak 3 km (A1) tanah terdampak erupsi jarak 6 km (A2) tanah terdampak
erupsi jarak 9 km (A3). Parameter yang diamati, pH H2O, C – organik, P – tersedia,
K – tersedia, Sulfur, P- Total, K-Total, tekstur, dan KPK. Analisis data dilakukan
dengan melakukan perhitungan berdasarkan hasil analisis laboratorium dan
dilakukan matching dengan perharkatan masing-masing unsur. Hasil penelitian
menunjukkan unsur hara P-tersedia pada A2 memiliki haarkat yang rendah. K-
tersedia pada jarak 6 km memiliki harkat yang rendah. Unsur hara S pada jarak
terdekat (A1) memiliki harkat yang sangat tinggi. Jarak tersebut juga berpengaruh
terhadap pH, tekstur tanah pasir geluhan, C-organik, KPK tanah dominan rendah, P-
total yang memiliki harkat tertinggi pada jarak 3 km. K-total keseluruhan memiliki
harkat yang sangat rendah.
Kata kunci: Kerusakan, Fosfor, Kalium, Sulfur, Jagung dan Erupsi.

STUDY OF P, K, AND S NUTRIENTS IN SOIL AFFECTED BY THE
ERUPTION OF MOUNT SINABUNG WITH CORN GROWING IN NAMAN
TERAN, KARO DISTRICT
By: Fanny Natasya Endamia br Ginting
Supervised by: Lelanti Peniwiratri and Didi saidi
ABSTRACT
The availability of P, K, and S nutrients has an important role in the productivity of
corn plants. The eruption of Mount Sinabung had the effect of reducing the availability
of nutrients in the soil, especially P, K, and S. This study aims to assess the levels of P,
K, and S nutrients in the rehabilitation soil of the eruption of Mount Sinabung which is
grown with corn in Naman Teran sub-district, Karo Regency, North Sumatra. This
study used a survey method with 4 sampling points. Land not affected by eruption
distance (A0), eruption recovery land distance 3 km (A1) eruption recovery land
distance 6 km (A2) eruption recovery land distance 9 km (A3). Parameters observed
were pH H2O, C – organic, P – available, K – available, Sulfur, P-Total, K-Total,
texture, and KPK. Data analysis was carried out by calculating based on the results of
laboratory analysis and matching with the value of each element. The results showed
that available P nutrients in A2 had a low level. K-available at a distance of 6 km has
a low price. The S nutrient at the closest distance (A1) has a very high value. This
distance also affects pH, soil texture of loamy sand, C-organic, low dominant soil CEC,
and P-total which has the highest value at a distance of 3 km. K-total as a whole has a
very low rating.
