Abstract

Effect of Liquid Organic Fertilizer from Nata de coco Waste and Cow Manure in Anaerobic Digester Processing Application in Soil Chemistry Properties of Lettuce PlantingABSTRACT. The objective of this experiment was to study effect of liquid organic fertilizer from nata de coco waste and cow manure in anaerobic digester processing application in soil chemistry properties of lettuce planting. The experiment is conducted at Physical Chemistry and Environmental Laboratory of IPB and in Jabon Mekar Village, Parung, West Java. The treatment of this experiment is application of liquid fertilizer (organic fertilizer) once, twice, and three time a week from effluent anaerobic digester 75% nata de coco waste + 25% cow manure, 50% nata de coco waste + 50% cow manure, 25% nata de coco waste + 75% cow manure, and 100% cow manure compared with control (inorganic fertilizer) on lettuce. The result showed that the application of liquid organic fertilizer from nata de coco waste and cow manure in anaerobic digester processing can increase the soil chemistry properties.

Abstract

Micro Elements in Liquid Organic Fertilizer from Nata de coco Waste and Cow Manure in Aerobic Digester Processing and Its Influence to Lettuce CropABSTRACT. The objective of this experiment are to study micro elements in liquid organic fertilizer and to find optimal interval time of the liquid organic fertilizer application to increase lettuce yield. The experiment is conducted at Physical Chemistry and Environmental Laboratory of IPB and in Jabon Mekar Village, Parung, West Java. The treatment of this experiment is application of liquid fertilizer (organic fertilizer) once (S1), twice (S2), and three time a week (S3) from effluent anaerobic digester 75% nata de coco waste + 25% cow manure (T1), 50% nata de coco waste + 50% cow manure (T2), 25% nata de coco waste + 75% cow manure (T3), and 100% cow manure (T4) compared with control (inorganic fertilizer) on lettuce. The result shows that there are some micro elements in liquid organic fertilizer. The application of liquid organic fertilizer in twice a week in 100% cow manure (T4S2) gives the best lettuce yield (96,587 g).

Abstract

The presence of heavy metal in soil can reduce the productivity of soil and the quality of agricultural products. The effort for handling the Pb heavy metal pollution in soil is by adding ameliorant. An experiment was conducted with objectives to study zeolit, organic matter and carbon active evectivenees to plant growth, Pb absorption and solubility of Pb in soils, The research was held in a center of vegetable plant on Tegal district. Randomized completely block design used with three replications at 1.20 m x 4.50 m (5.00 m2). Treatment were control, zeolite (1, 2 and 3 tons ha-1), organic matter (5, 10 and 15 tons ha-1), and active carbon (0.5, 1 and 1.5 tons ha-1). The observed parameters were plant height, amount of tuber at 2 nd, 4th, 6th, and 8th weeks after cultivation, wet weight, and dry weight of leaves and bulb, availibility of Pb (Olsen-EDTA extract) in soil, and Pb adsorption in leaves and bulb of onion. Quantitatively, the ameliorant can reduce Pb adsorption in leaves and bulb of onion. Zeolite treatment with 3 tons ha-1 is more effective to reduce the Pb adsorption in leaves and bulb of onion.
