Abstract

This study aims to determine: 1) evaluate the distribution of total N and the distribution of heavy metals Cu and Zn in paddy fields in the Cikijing River Irrigation Area, Rancaekek District, 2) the amount of total N and the distribution of heavy metals Cu and Zn in paddy fields in the Cikijing River Irrigation Area, Rancaekek District. The experiment was conducted in paddy fields contaminated with factory waste in the Cikijing River Watershed, Rancaekek District and followed with the analysis of the soil at the Laboratory of Soil Fertility and Plant Nutrition, Faculty of Agriculture, Padjadjaran University. The experiment was conducted in February 2017 to November 2017. The determination of sample points is based on Homogeneous Soil Map Unit (SLH), which is made by overlay map on the map of soil types, slope maps and land use maps of research areas. The number of samples is 8, which is located on the 5 villages. The variables observed and measured in this study included total N and heavy metals Cu and Zn. The results showed that the total N in the research area was low and moderate, but at some location points there was a very low N content, while heavy metal Cu at several locations was above the quality standard and heavy metal Zn was above the quality standard.

Abstract

This study aims to determine1) the amount of nutrient content of Sulphur in a paddy field in the irrigation channel of Arca Kirit dam in Banyumas Regency, 2) nutrient distribution of Sulphur in paddy field in the irrigation channel of Arca Kiri dam in Banyumas Regency, and 3) recommendations of Sulphur fertilizers in paddy field in the irrigation channel of Arca Kiri dam in Banyumas Regency. The research was conducted in paddy field, in the irrigation channel of Arca Kiri dam in Banyumas Regency, then continued with analysis of the soil in the Institute of Determining Technology of Agriculture (BPTP), Yogyakarta. The research carried out by the determination of sample points based on a purposive random sampling be based Land Homogenous Unit (SLH). Land Homogenous Unit arranged by overlaying the Administrative Map, Slope Map, and Soil Type Map. The number of samples is 8, which is located in 5 villages. The variables were observed namely the nutrient content of Sulphur, EC, pH (H2O), and BS of land. The results showed that the nutrient content of Sulphur from both SLH relatively high, there were SLH A1 reach 86.20 ppm and SLH A2 reach 85.33 ppm. Sulphur fertilizer recommendations for SLH A1 is 10.64 kg S/ha and SLH A2 is 14.60 kg S/ha.

Abstract

Penelitian ini bertujuan untuk: 1) mengevaluasi sebaran pencemaran ketersediaan logam berat (Pb, Cd dan Cr) dari pembuangan limbah pabrik tekstil terhadap tanah sawah di daerah pengairan Sungai Cikijing Kecamatan Rancaekek, 2) mengkaji kandungan ketersediaan logam berat (Pb, Cd dan Cr) dan bahan organik yang terdapat pada tanah sawah di daerah pengairan Sungai Cikijing Kecamatan Rancaekek. Penelitian dilaksanakan pada lahan sawah tercemar logam berat dari limbah pabrik tekstil dari pengairan sungai Cikijing Kecamatan Rancaekek dan dilanjutkan dengan analisis tanah di Laboratorium Kesuburan Tanah dan Nutrisi Tanaman Fakultas Pertanian Universitas Padjadjaran. Penelitian dilakukan dengan penetapan titik sampel didasarkan kepada sistem purposive random sampling. Jumlah sampel adalah 50 yang terletak pada 4 desa. Variabel yang diamati dan diukur dalam penelitian ini meliputi variabel utama yaitu kandungan ketersediaan logam berat (Pb, Cd, dan Cr) dan variabel pendukung meliputi C-organik tanah. Hasil penelitian menunjukkan bahwa kandungan ketersediaan logam berat setiap lokasi sampel masih berada dibawah batas kritis untuk logam berat Pb, Cd dan Cr.
