      Abstract
      Tailing dengan kandungan logam berat yang tinggi dapat merusak sifat kimia tanah dan umumnya memiliki pH yang tidak stabil. Penelitian ini bertujuan mengaplikasikan pupuk organik padat dalam memperbaiki kualitas lahan bekas tambang emas dan mengurangi kadar logam berat Pb yang ada di limbah hasil pertambangan emas menggunakan tanaman jarak pagar (Jatropha curcas L.) sebagai parameternya. Tailing diambil dari PT Antam Emas Bogor. Terdapat 3 perlakuan nisbah campuran pupuk organik padat terhadap tailing, yaitu A (100:0), B (50:50), dan C (0:100). Parameter uji pada media tanam adalah pH dan Nitrogen Fosfor Kalium (NPK), sedangkan pengamatan pada tanaman jarak pagar meliputi pengukuran tinggi tanaman dan pertambahan jumlah daun. Nilai NPK yang memiliki nilai tertinggi ialah pada perlakuan A, diikuti oleh B, dan C. Hasil ini menunjukkan pemberian pupuk organik padat pada tanaman akan berpengaruh pada pertumbuhan tinggi dan jumlah daun pada tanaman Kata kunci: NPK, pupuk, tailing
       
      Tailings with a high heavy metal content can damage the chemical properties of the soil and generally has an unstable pH. This research aims to apply solid organic fertilizer to improve the quality of ex-gold mining land and reduce levels of the heavy metal Pb in gold mining waste using jatropha plants (Jatropha curcas L.) as the parameter. Tailings waste is taken from PT Antam Emas Bogor. There are 3 ratio treatments of solid organic fertilizer mixture to tailings, namely A (100:0), B (50:50), and C (0:100). The test parameters on the planting media are pH and Nitrogen Phosphorus Potassium (NPK), while observations on Jatropha plants include measuring plant height and increase in the number of leaves. The NPK value that has the highest value is in treatment A, followed by B, and C. These results show that giving solid organic fertilizer to plants will affect the height growth and number of leaves on the plants. Keywords: fertilizer, lead, NPK
