<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[Fertilizer is one of nutrient sources that very important for increasing agricultural production besides improvement of soil properties by application of soil amendments such as zeolites and compost. Addition of zeolites increase the cation exchange capacity (CEC) and fertilizer effeciency while compost used as source organic matter and nutrients in the soil. Estiaty (2005) showed that application of 20 ton/ha zeolite and chicken manure compost 10 ton/ha with basal fertilizers of N, P, K 200 kg/ha respectively is the best dosage for Ipomoea reptans. From the second period showed that there was higher nutrient residue in the soil applied by zeolite and chicken manure compost. These facts were shown from better plant growth and production in the soil applied by zeolite in the second period. The objective of this experiment is to calculate the residue of nutrients from the application of zeolite and chicken manure in the first planting before. The experiment was conducted by application of N, P, and K fertilizers in different rates in the soils after using first planting with zeolite and chicken manure. Ipomoea reptans was used as indicator plant. Experiment was conducted in two stages; first planting such as Estiaty (2005) treatments following by second planting with N, P, K in different dosages. This experiment was conducted in green house of Cikabayan, IPB Darmaga Campus while soil and plant analysis was conducted in the laboratory of Department of Soil Science and Land Management. The result showed that zeolite and chicken manure increase the efficiency of N, P, K fertilizers in the second planting. In the second planting of Ipomoea reptans, the need of N, P, K fertilizers were only half of the first planting with the production of nearly the same. Application of zeolite and chicken manure was not only increase the efficiency of N but also increase the available of P and K in the soil.]]>

<![CDATA[Planting media and host crop play an important role in determining inoculum mass production of Mycorrhiza arbuskula (CMA). Planting media used in this research consist of zeolite, sand, and soil and the host crop are S. bicolor, S. splendida, C. javanica, C. pubescens. Host crop S. bicolor could be respectively replaced by S. splendida with zeolite as the best planting media in order to produce mass of CMA. In the other hand, mass production of CMA by the combination of S. splendida and soil as planting media could work well under condition that inoculum added in twofold dosage. Using of P. javanica and C. pubescens with zeolite as a planting media was found as the best combination. And the combination of C. pubescens and soil as a planting media could be used also under condition that inoculum added in twofold dosage.]]>

<![CDATA[The objective of this research was to study the growth and efficiency of broiler productivity. The research was conducted through the application of zeolite spreading treatment into the broiler housing in Non-ruminant Research Station of Animal Science Laboratory of Papua State University. Study was arranged by Randomized Sample Design with four treatments: P0 (control; without zeolite spreading); P1 (once time spreading during the research period); P3 (three times application of spreading during the research period); and P5 (five times of spreading or once a week during the research period). The application of zeolite spreading was not significantly influenced the rate growth of broiler, though there is a tendency increasing weight gain along with the increased in zeolite spreading level on the litter base. P3 (three times of zeolite spreading during research) produce the feed efficiency of 0.53. Economically, Income Over Feed Chick and Zeolite Cost (IOFCZC) per head per housing unit with the application of zeolite spreading more demand compared to housing units without spreading treatment.]]>

<![CDATA[The decrease of hardness (Ca, Mg) and heavy metal (Fe, Mn, Zn) contents in raw water was conducted by flowing the sample water through the activated zeolite bed column. Treated water obtained from the experiment obviously met the parameter in standard requirement of drinking water. Activated natural zeolite from Cikalong, Tasikmalaya is able to decrease the content of Ca, Mg, Fe, and Mn in the sample water through the cation exchange process by percolation method with the optimum flow rate of 5 volume bed/hour on the zeolite with the particle size of -10+18 mesh especially for decreasing the hardness (Ca and Mg content). On the other hand, optimum condition for decreasing Fe and Mn contents are reached on the zeolite with the particle size of -10+18 mesh and water flow rate of 10 volume bed/hour. The final treated water contained 0,08 ppm Mn and 0,024 ppm Zn, meanwhile the hardness and other cations have been reduced below the required limit value (0,30 ppm for Fe, 0,10 ppm for Mn, and 0,05 ppm for Zn).]]>
