<![CDATA[Nowadays, Indonesia suffer a serious economic crisis. The situation is mainly caused by national industrial development strategy which is depend on import materials, e.g. in agriculture. In the cases, the national need are depend on import fertilizer, so that makes the national food stock become decreasing. This research is designed to offer another alternative in preparing and producing own fertilizer that we need, to solve the problem. New compotition of Animal manure has been made by addition of natural zeolite to gain a high nitrogen content. Characterisation analysis of materials included chemical composition of natural zeolite and manure fertilizer using AAS and Kyedhal analysis, structure analysis by XRD and SEM and CEC. The result of experiments showed that addition of natural zeolite to excrement (animal waste) increased the content of nitrogen and decreased the content of water in manure fertilizer. Ammonia absorption by natural zeolite with particle size of either "“8+14 or 14+20 mesh was almost similar. The nitrogen content of manure fertilizer which mixed with natural zeolite from kedung Banteng, Malang was bigger than that which mixed with natural zeolite from Cikancra, Tasikmalaya. The adsorbtion of water by natural zeolite of both particle sizes was also similar. Manure fertilizer which mixed with natural zeolite from Kedung Banteng was dryer than that which mixed with natural zeolite from Cikancra, Tasikmalaya. The improved animal manure has better properties like a high nitrogen content, dry and not malodorous.]]>

<![CDATA[The simulation analysis of natural zeolite crystal structure have been carried out using RIETAN program. The simulation results provide diffraction pattern of some crystal structure data representing as zeolite materials. There are two sets of input data: First Global parameter: a. parameter to correct the zero-point shift of the diffraction pattern: zero-point error,Z, b. parameter to calculate the background: background parameters. Second: Phase-dependent parameters: a. parameter to adjust integrated intensities:scale factor,S, b. prefered orientation parameters, c. profile parameters:FWHM parameters,d parameters to determine peak position: lattice parameters and e.crystal structure parameters: fractional coordinates. The output data contain some information such as:profile diffraction pattern, R factor, final adjusted parameters and their estimated standard deviations, lattice parameters and unit cell volume, structure parameters, number and weight of each species in the unit cell and density,and summary of reflection such as: hkl, 2 theta, d, observation intensity, calculated intensities and structure factors. These output data provide diffraction patterns for some zeolite phases, i.e.: clinoptilolite, heulandite, mordenite, analcime, phillipsite, chabazite and erionite. Results show that was significant and the application can be used for all kind of zeolites and other crystal materials in general applications. The program can be applied easily and the resulting patterns represent all phases significandly. RIETAN simulation program is expected to help hope that helpful suggestion for all people who are identification and characterisation of zeolites qualitatively.]]>

<![CDATA[Selectivity of zeolite-lampung (ZKK) towards some matrices cations generated from uranium fission products has been investigated using some typical fission product-non-radioactive cations by cation exchange batch-system process. The previous investigation showed that zeolite-lampung is effectively able to absorb cesium ion from radioactive waste, consequently the presence of others cations i.e. generated cations from the uranium fission products are assumed as the competitive cations which may affect the zeolite selectivity on to Cs exchanges, on the otherhand the Cs-exchange capacity of zeolite would decrease. The main matrices cations which present in the natural zeolite are K+, Na+ and Ca2+and those are generated from fission products such as Cs+, Ba2+, Sr2+ and Ce4+ exist in the nuclear spent fuel solution. The ion exchanges of counterpart cations in zeolites with that each of Cs+, Ba2+, Sr2+ and Ce4+ ion or/and its mixtures have been examined. The selectivity of zeolite onto mentioned exchanged cations has been shown by the correlation of fraction of the cations concentration in the zeolite (Az) towards that in equilibrated solution (As). The results show that the raw zeolite Lampung selectivity is decrease in order to Cs+> Ba2+= Sr2+ > Ce4+. The exchanged capacity of zeolite into Cs+ ion is decreased by the presence of combining ions of Ba2+, Sr2+ and Ce4+, and so are those competitive cations.]]>

<![CDATA[The objectives of this research is to know the effects of zeolite and blood flour rate effects as the source of protein on ransom on pig carcass quality. Pig carcass quality is influenced by several factors before and after slaughtering. One of the factors that influences pig carcass before slaughtering is feeding. The right feeding can fulfill the pig needs and increases the pig carcass quality. The average weight of 27 pigs used on this research is 25,59 ± 2,67 kg and the research design is 3´3 complete randomize design which the first factor is zeolite rate (0, 3, and 6%) and second rate is blood flour rate (0, 5, and 10%), so we have nine treatments ransom (R1 to R9) with three repetition on each treatment. The result showed that zeolite rate on ransom did not affect any parameter (P>0,05) and neither the blood flour, except for the loin eye area larger than 10% and without blood flour on ransom with the scores 31,16 ± 4,25; 27,74 ± 3,32, and 29,18 ± 4,85 cm2. The effect of interaction between zeolite rate and blood flour on ransom is very real (P0,05) on carcass percentage and the thickness of pig carcass back fat. The highest and the lowest slaughter weight and carcass weight is the pig whose have R5 and R4. The highest average of back fat thickness and loin eye area is the pig whose have R8 and R4 is the lowest. The pig whose have R7 and R4 each have the longest and shortest carcass while the highest carcass percentage is the pig whose have R4 and the lowest is R6.]]>

<![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-silicaphosphate (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[The zeolite membrane of MFI could be sinthesized on alpha alumina support having an asymmetric structure and a pore diameter of top layer being about 0.1 μm. In this experiment, the method performed was a hydrothermal process being done at temperature 303 K by using Silica colloidal with the the composition of 30% SiO2, 0.04% Al2O3, 0.4% Na2O and NaOH 4N. The membranes produced were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray diffraction (XRD), Energy Dispersive X-ray Spectrofotometer (EDX) and gas permeation, which use some pure gases such as carbon dioksida, methane, n-butane and ibutane. Based on the SEM observation, the top layer of MFI zeolite membrane produced was about 20 μm. The Analysis and mapping by using EDX showed that the zeolite membane was formed on top and inside of the support. Based on the gas permeation test, the permeance of nitrogen increased while the temperature encreased, and the result showed that the permeance ratio of n-butane/i-butane was about 60. Meanwhile, the selectivity of n-butane/i-butane at 300 K was 62. The simulation test of gas separation was performed by applying the mixture of nbutane and i-butane as a model and the temperature variation of 300 K, 340 K and 380 K. In this case, the Test used a pervaporation methode in which helium as inert gas (i.e. sweep gas) and on line analysis by using gas chromatography. The Flux of gas being through the membrane was measured by flow meter. The Selectivity of the mixture of n-butane and i-butane at temperature 300 K obtained was 62, and its selectivity decreased while the temperature increased.]]>
