This study aimed to determine the effect of biochar, compost, and organic pesticides on the growth and yield of shallot, and the activity of microorganisms in the soil. The study was conducted in Klampok Village, Wanasari, Brebes Regency from January to July 2020 using a complete randomized block design with nine treatments which were a combination of biochar, compost, organic pesticides, recommended dose of pesticides, and farmers’ dose of pesticides. The shallot seed used was the Bima Brebes variety. Soil characteristics, compost nutrient contents, plant growth, shallot yield, and total soil bacteria population were measured. The study showed that the yield of shallot was 16.7 tons/ha obtained from adding compost and recommended dose...

The number of anthropogenic activities in the area causes the accumulation of heavy metal contamination in the soil. This study aimed to determine the heavy metal content of Cadmium (Cd) in three regencies of shallot production centers in Central Java. The study was conducted in three regencies of shallot production centers in Central Java: Pati, Demak, and Brebes Regency. Soil samples were taken by the purposive sampling method. The highest Cd content was found in Brebes Regency at 3.53 mg kg-1, and the lowest was in Pati Regency with a value of 1.10 mg kg-1. The value of the geoaccumulation index shows the presence of Cd contamination from anthropogenic activities. In Pati and Demak Recency contaminated with Cd with moderate to heavy status, Brebes Regency showed Cd contamination as serious. The high content of Cd in the Brebes Regency with severe contamination status is thought to be due to the intensity of cultivation and the increased use of agrochemicals, fertilizers, and pesticides.

The study purposed to assess the level of metal contamination using statistical analysis, contamination factor (CF), geo-accumulation index (I-geo), and load pollution index (PLI). In this research, a total of 18 topsoil samples were taken and analyzed for the several metal concentrations are Pb, Cd, Cr, Co, and Ni. The concentration of heavy metals in soil samples was in the order of Cr > Ni > Pb > Co > Cd. The I-geo values of Pb, Co, Ni, and Cr indicated uncontaminated soils, while I-geo values for Cd showed level contamination in soil was uncontaminated to moderately contaminated. The values of pollution load index (PLI) indicated that these observed samples in agricultural soils for shallot in Wanasari, Brebes Regency were uncontaminated.

Improvement of agricultural land quality using fitoremediation is needed to overcome heavy metal pollution. The reasearch aims to make remedies for paddy field polluted by cadmium (Cd) and copper (Cu) using plants that have the ability to absorb heavy metals in order to increase the quality of the land. This research was conducted at the screen house of Indonesian Agricultural Enviroment Research Institute, using a Randomize Block Design (RBD). Hyperaccumulator treatment plant, consisting of T1: mendong (Fimbristylis globulosa), T2: grass types tekian (Cyperus platystylis), T3: jugul (Borreria laevis), T4: spinach (Amaranthus spp.), T5: mustard (Brassica juncea), T6: bundung ganal (Scleria poaeformis), T7: purun tikus (Eleocharis dulcis), T8: karapiting (Polygonum hydropiper), T9: hiring-hiring (Rhynchosphora corynbosa), and T10: purun kudung (Leperonia mucrunata).

This study aims to analyze the distribution of heavy metals in agricultural land in Batu City and analyze the public health risks associated with metal concentrations in agricultural land. This study used a survey method for taking soil samples with a total of 292 points for taking soil samples. The analyzes performed included spatial analysis, correlation analysis, multivariate analysis, cluster analysis, and health risk analysis. The results of this study indicate that the concentrations of heavy metals Cd, Co, and As in agricultural land in Batu City have exceeded the critical limits (3, 25, and 2 mg kg-1). The spatial distribution shows that Pb, Cd, Co, Cr, Ni, Cu, and Zn are almost evenly distributed in all classifications. Multivariate analysis showed the presence of natural and...

Its superior commodities include paddy rice, tea, tobacco, coffee, and vegetable plants. In the practice of agricultural activities, it is inseparable from the use of inorganic fertilizers and persistent chemical pesticides that cause heavy metal contamination in agricultural land. Industrial waste around agricultural land that enters the water body also contributes to the accumulation of heavy metals in the soil of the water for irrigation. This study aimed to determine the distribution of heavy metal content of Pb, Cd, Ni, Co, Cr, and As on the agricultural land of Wonosobo Regency. The study was conducted on the agricultural land of Wonosobo Regency. As many as 312 soil samples were taken from a layer of sports (depth of 0-20 cm) of agricultural land in ten sub-districts of Wonosobo Regency. Soil sample analysis included heavy metals Pb, Cd, Ni, Co, Cr, As, organic Carbon, CEC, and soil textur...

Pertumbuhan industri yang meningkat dengan pesat di wilayah Daerah Aliran Sungai memungkinkan terjadinya pencemaran berbagai jenis logam berat di lahan sawah. Tujuan penelitian ini adalah mengkaji kemampuan tanaman mendong (Fimbristylis globulosa) yang ditanam dengan inokulasi bakteri penghasil eksopolisakarida Azotobacter maupun arang aktif dalam menurunkan kandungan kadmium (Cd) dan timbal (Pb) dari tanah serta meningkatkan serapannya di tanaman mendong. Penelitian rumah kaca ini menggunakan Rancangan Acak Kelompok dengan empat perlakuan yang diulang tiga kali. Hasil penelitian menunjukkan bahwa saat mendong berumur 4 minggu, inokulasi Azotobacter dengan dan tanpa arang aktif menurunkan kandungan Pb tanah, tetapi baik Azotobacter maupun arang aktif tidak mempengaruhi kadar Cd dan Pb di tajuk dan akar mendong. Namun, empat minggu kemudian, Azotobacter ma...

In general, tailings contain very low organic carbon and plant nutrients but are high in mercury and have extreme soil acidity. The objective of this study was to observe the growth of various legume cover crops (LCC) and the change of Hg in tailing inoculated with Azotobacter-Trichoderma. The field trial was conducted on Buru Island of Maluku by using a split-plot design with three replications. The main plot was LCC species, composed of Centrosema pubescens (CP), Mucuna sp. (MC), and Crotalaria sp. (CR); the subplots were microbial inoculants composed of two formulations of Azotobacter-Trochoderma inoculants. The results showed that the Mucuna sp. and consortia Azotobacter-Trichoderma (2:1) had the highest survival rate in the tailings and Hg uptake by 8.83 mg kg-1 per plant. Consortia Azotobacter-Trichoderma inoculant with the ...

EPA ( Environmental Protection Agency ) menerangkan bahwa Arsen (As) bentuk organik (mengandung karbon), misalnya monosodium methanearsenate dan dinatrium methanearsenate digunakan dalam pestisida untuk aplikasi pertanian. Salah satu dampak dari paparan pestisida yangmengandung Arsen (As) adalah anemia. Mengingat beras masih merupakan makanan pokok di Indonesia, penelitian ini perlu dilakukan. Dengan mengetahui kandungan As dalam beras yang dihasilkan dari lahan sawah yang terkontaminasi As, maka dapat diketahui sejauh mana beras tersebut aman untuk dikonsumsi oleh manusia.
