Abstract

Naturally, zeolite is a cation exchanger but this property is also depending on porosity, tetrahedral density and frame density. Cation exchange effectiveness can be changed by structure, Si/Al ratio and effective pore size. Tetrahedral group, T, in zeolite is negative charged and can be substituted isomorphycally by other group like PO2+. The new structure can be functioned as anion or cation exchanger. The exchange capacity of both ions depends on Si/Al/P ratio from the substitution process. The alumina-silica-phosphate (ASP) compound has been made from zeolite from Cikalong, Tasikmalaya, with ammonium dihydrogen phosphate (ADHP) with substitution rate between 30-40%. This product has been tested to Pantura groundwater, in Bekasi and Karawang areas, which have groundwater type of NaCl, CaCl2, MgSO4 and CaCl2/CaSO4. ASP tests on ground water samples show decreasing content of Ca, Mg, Na and K cations in ground water by 32.94%, 3.35%, 2.52% and 23.60% respectively. Sulphate anion also decreases by 15.39% but chloride anion shows no changes. Dig-up well of CaCl2 type also shows a reduction of Ca, Mg, Na and sulphate contents by 46.26%, 18.37%, 16.39% and 10.84%, respectively. Dig-up well of CaSO4 type shows Ca, K and sulphate contents decrease of 89.71%, 33.31% and 5.26%, respectively. CaSO4 dig-up well can be changed to Mg-mix type after processing by ASP compound. Cation exchange capacity of ASP compound to Ca is higher than to K, Mg and Na (Ca>K>Mg>Na). Due to a high cation exchange capacity to K and Mg, ASP compound may be used to reduce the hard water level.

Abstract

This research was conducted to evaluate that the effect of zeolite addition in ration on egg quality in phase two of production. This experiment was arranged in a completely randomize design with 5 zeolite levels in rations (0; 2; 4; 6 and 8%) and 4 replications. The total hens were 40 of CP 909 (60 weeks of age), and this experiment was done 4 weeks. The parameters that: feed consumption, the shell thickness, fat of yolk levels, and cholesterol of yolk levels. The data were analyse by using Analysis of Variance, and orthogonal polynom test was used , analysis were in 5% significant degree. The result of this research showed that zeolite addition in ration until 8% had significant effect (P0.05) on cholesterol of yolk levels and feed consumption.

Abstract

Directly reuse of fly ash waste from electricity power plant as soil conditioner is often not recommended, because of its content on heavy metals elements. This research studied the existence of metal elements, Ni, Pb, Cr and Cd in the zeolitization products of fly ash produced in PLTU Suralaya. Zeolitization process was conducted hydrothermal using NaOH solutions of 3N and 4N at temperature of 90oC and 120oC and heating time of 12 hours, 24 hours and 48 hours. 10 kinds of zeolite products were identified as a mixture of zeolite Na-PI, Na6(Si10Al6O32).12H2O and zeolite Na Hydroxysodalite, Na6(SiAlO4)6.4H2O, which had cation-exchange capacity much higher than the original fly ash. Metals ions content of Ni, Pb, Cr and Cd in the zeolite products, analyzed by AAS, were found much decrease compared to its content in the fly ash. Further study on leaching of metals ions from the zeolite products with water on pH neutral did not show a significant losses of these metals ions.

Abstract

Manure contains micro and macro nutrients which are essential for plant growth. During the decomposition process and after application to the soil, nutrients in manure especially nitrogen is easily volatile to the atmosphere and leaching by water. Zeolite has a high adsorption to ammonium ion, so the application of zeolite together with manure may improve the plant growth. The objective of this research is to evaluate the effect of manure and zeolite addition to the growth and absorption of plant nutrients of Ipomoea reptans. This research was conducted in green house of Department of Soil Science, Faculty of Agriculture, Bogor Agricultural University, from June until October 2004. Cultivation was conducted in two period. Immediately after the plant were harvested in first period, plant media were cultivated for the second period without addition of fertilizers. Addition of 20 ton/ha zeolite to the plant media influence the growth and absorption of nutrient higher than the other zeolite treatments. Nutrient residue of zeolite treatment is higher than the treatment without zeolite which is shown by higher production of Ipomoea reptans in the second planting period. Application of zeolite increase the growth of plant. Application of zeolite together with chicken manure gave higher growth and production compared with cattle manure.

Abstract

Zeolite used in so various area and inclusive of livestock. The using of zeolite is related to zeolite characteristic as molecule absorber and cation exchange capacity. In return for cation, because metallic binding which owning is easy to release and also easily replace by cation of other. Zeolite ability as molecule absorber caused by its structure is hollow where other molecule that selectively can dissociate molecule which size measure is bigger can fill the cavity. Nature zeolite ability causes it a lot of used for the good livestock area as part of feed and as media of plant for livestock feed and also to improve environmental quality of farm. Zeolite use in research of various livestock type show livestock appearance repair improvement and low feed price. Zeolite use to improve environmental quality also show real result through rate reduction irrigate dirt, dirty air and dirt ammonia rate degradation in cage and also lessen aroma coming from ammonia (NH3) and sulphide hydrogen (H2S) as ferment micro organism result in feces.

Abstract

Framework structures of clinoptilolite and mordenite phases in natural zeolit from Bayah have been succesfully analysed using Rietveld Method. The diffraction intensity data were collected using X-Ray Difractometer (XRD) at P3IB-BATAN. The refinement of the clinoptilolite and mordenite phases have been carried out and the results show that there are poly cation K-Mg clinoptilolite phase, with space group symmetry of C2/m No.12, monoclinic crystal system and poly cation Ca-Na mordenite phase, with space group symmetry of Cmcm No.63, orthorombic crystal system. Chemical formulas of clinoptilolite and mordenite phases are (K5,17 Mg0,16) (Al6Si30O72). 24H2O and [(Na 5,63 Ca 1,13) (Al8Si40O96). 22H2O per unit cell respectively. Fitting quality (goodness-of-fit) gave a value of Rwp = 10,34%.

Abstract

Sweet potatoes are more sensitive to fertilization of Nitrogen (N) and Potassium (K), among other macro nutrient elements. Theoretically, in order to produce one ton of this comodity, at least 3 kg N, 9 kg K, and 2 kg P are needed. But in fact actually, urea as a Nitrogen source that might be added to soil commonly evaporated in other way the KCl as the Potassium fertilizer easily leached down from soil profile and thus the plant productivity much lower. Objectives of this research are to study the influence of zeolites addition to increasement of nutrient absorption in soil by Sweet Potatoes. The research was conducted from February - June 2003 in District of Katibung, Jati Agung, Merbau Mataram, then from March-July 2003 in District of Panjang, and April-August 2003 in District of Waway Karya by using Complete Randomized Block Design with 3 replication. Each plot consists of 7 planting area (sized 35 m2) and planting distance is 100 cm x 25 cm, or plant density 140/plot. Zeolites is applied in application level of 30 % from total weight of fertilizer 350 kg/Ha. Bedeng size measure 30 cm and wide 60 cm. Zeolite used with dose 30 % from or equals to 105 kg zeolites/ Ha, Result of crop yield that showed by tuber weight both the small sized or the large sized tuber are optimalized in treatment C which 105 kg/ha zeolite. It could be explained because addition of zeolites in fertilizer increase the nutrient absorption by the crop planted. In all research locations, treatment C yielded the most beneficiary production of Sweet potatoes. Tuber root weight in Chinesse Fertilizing treatment lower than other fertilizer because the nutrients are much slower released in the soil profile.
