Jawaban:

To calculate the amount of UREA, SSP, and MOP required for 2 hectares of eggplant field, we need to know the recommended amount of NPK fertilizer per hectare.

Assuming the recommended dose of NPK fertilizer for eggplant is 150:70:50 kg/ha, then for 2 hectares, the total amount of NPK fertilizer required is:

N = 150 kg/ha x 2 ha = 300 kg

P = 70 kg/ha x 2 ha = 140 kg

K = 50 kg/ha x 2 ha = 100 kg

Now we can calculate the amount of UREA, SSP, and MOP required to provide the required amount of N, P, and K:

Amount of UREA = (N / 0.46) = (300 / 0.46) = 652.17 kg

Amount of SSP = (P / 0.16) = (140 / 0.16) = 875 kg

Amount of MOP = (K / 0.60) = (100 / 0.60) = 166.67 kg

Therefore, for 2 hectares of eggplant field, we need 652.17 kg of UREA, 875 kg of SSP, and 166.67 kg of MOP to provide the recommended dose of NPK fertilizer.

Penjelasan:

Luas lahan terong seluas 2 hektar sama dengan 20.000 meter persegi (m²).

Untuk menghitung kebutuhan pupuk, kita harus menghitung terlebih dahulu berapa banyak N, P, dan K yang dibutuhkan untuk luas lahan tersebut dengan rumus:

N = dosis NPK x luas lahan x kadar N

P = dosis NPK x luas lahan x kadar P

K = dosis NPK x luas lahan x kadar K

Diketahui:

Luas lahan = 20.000 m²

Dosis NPK = 150:70:50

Kadar N di Urea = 46%

Kadar P di SSP = 16%

Kadar K di MOP = 60%

Maka,

N = 150/100 x 20.000 x 46/100 = 13.800 kg

P = 70/100 x 20.000 x 16/100 = 2.240 kg

K = 50/100 x 20.000 x 60/100 = 6.000 kg

Dari hasil tersebut, kita dapat menghitung kebutuhan pupuk UREA, SSP, dan MOP dengan cara:

UREA = N/kadar N di Urea

SSP = P/kadar P di SSP

MOP = K/kadar K di MOP

Maka,

UREA = 13.800/46% = 30.000 kg atau 30 ton

SSP = 2.240/16% = 14.000 kg atau 14 ton

MOP = 6.000/60% = 10.000 kg atau 10 ton

Jadi, untuk lahan terong seluas 2 hektar dengan dosis rekomendasi NPK 150:70:50, dibutuhkan 30 ton UREA, 14 ton SSP, dan 10 ton MOP.
