ABSTRAKSalah satu industri yang menghasilkan limbah cair yang mengandung logam berat adalah industri kertas dan pulp. Tujuan penelitian ini adalah untuk mengidentifikasi logam berat yang berada di lahan pertanian di sekitar industri kertas dan pulp di Kabupaten Malang. Penelitian dilaksanakan dengan mengambil beberapa sampel tanah dan air dilahan pertanian di sekitar industru tersebut. Penelitian dilaksanakan pada bulan Mei-Juni 2023. Hasil pengujian laboratorium menunjukkan  bahwa logam berat ditemukan pada sampel tanah pada lahan pertanian di sekitar industri kertas dan pulp yaitu timbal (Pb) dengan kandungan sebesar 3064 mg/liter, yang  melebihi nilai ambang batas, sedangkan kandungan Cadmium (Cd) (<0,0020 mg/liter) di bawah ambang batas, kandungan Corganik sedang dan pH tanah agak masam. Pada air limbah industri kertas dan pulp juga ditemukan kandungan Pb yang melebihi ambang batas, sedangkan kandungan Cd tidak melebihi nilai ambang batas. Hasil C Organik tanah masuk dalam kategori sedang dan untuk parameter pH H2O masuk dalam kategori agak masam. ABSTRACTOne of the industries that produces liquid waste containing heavy metals is the paper and pulp industry. The aim of this research is to identify heavy metals in agricultural land around the industry in Malang Regency. The research was carried out by taking several soil and water samples on agricultural land around the industry. The research was carried out in May-June 2023. Laboratory test results showed that heavy metals were found in soil samples on agricultural land around the paper and pulp industry, namely plumbum (Pb) with a content of 3064 mg/liter, which exceeds the threshold value, while the Cadmium (Cd) (<0.0020 mg/liter) is below the threshold, the C organic content is moderate and the soil pH is slightly acidic. In wastewater from the industry, it was also found that the Pb content exceeded the threshold value, while the Cd content did not. The soil C organic is in the medium category and the pH parameter H2O is in the slightly acidic category. ÂReferences
