Abstract

Zeolite synthesis from coal fly ash PLTU Tanjung Jati Japara was conducted by hydrothermal alkali. Preparation was done on fly-ash that has been refluxed with 1M of HCl and without refluxed. NaOH with certain concentration (2, 3, and 4M) was mixed with coal fly-ash by ratio 10 ml each 1 gram of fly ash into Teflon tube 100 ml at autoclave stainless-steel. Then, autoclave was heated on the oven at temperature of 120-1600C. Synthetic zeolite ouput was qualitative tested by using infrared spectroscopy, X-Ray diffraction, and SEM. The result showed that NaOH concentration, temperature, and hydrothermal alkali period of coal fly ash was affecting characterization of zeolite ouput. The temperature which use for optimally hydrothermal processes exist on range 140 –160oC. The increase of temperature causes improving crystallization of zeolite products. Hydrothermal synthetic product from fly ash is alumina-silica compound which are a mixture of some crystals such as P zeolite, Y zeolite, sodalite, mullite, and quartz.

Abstract

Coal fly ash (CFA) is the waste of coal usage that requires serious attention on handling because it is have the large quantity and containing a dangerous substances for environmental. The interesting method of waste processing of CFA is using CFA as zeolite raw material because CFA have a rich silicate and alumina. In this study, CFA is used as a raw material for zeolite synthesis nanoporous (ZSM-5) so that expected could be a solution for waste processing of CFA and also could be deliver a valuable materials that needed on many applications. Based on the result of characterization XRD and SEM, was known that structure of ZSM-5 and other zeolites (Na12Al12Si12O48.27H2O and Na0,3Al2,564Si100O203,996) have been successfully synthesized on hydrothermal processing at temperature of 97°C and the pressure of 1,3 bar.

Abstract

Coal fly ash was treated with alkali (NaOH) water solution by heating up to about 100 oC for 12 and 24 hours. The coal fly ash used in this experiment was obtained from PLTU (Steam Power Electric Station) Suralaya, West Java, Indonesia. It was passed through a wire sieve with filter size of 46 mm. The NaOH solutions were reacted 0.5, 1.0, 1.5, 2.5, 3.5 and 4.5 M. The final products of the reactions were designated as ‘artificial zeolites’. Result of this experiment indicated that the cation exchange capacity (CEC) of ‘artificial zeolites’ were increased by increasing NaOH concentration up to 2,5 M. Higher CEC value of the 24 hours treated coal fly ash than that of the 12 hour treated ones. The CEC of ‘artificial zeolites’ increased by about 50 time for the coal fly ash. The XRD (X-ray Diffraction) pattern of the coal fly ash treated by 2,5 M NaOH which had highest CEC value were present new crystalline matters (possibility phillipsite) with sharp diffraction peaks at 2.7, 3.2, 3.3, 4.1, 5.1, 7.1 Å. The infrared (IR) spectrum of the ‘artificial zeolite’ exhibited the broad absorption band around 1,000 cm-1 and at about 3,500 cm-1. The analyzed ‘artificial zeolite’ showed steep descent around 100 oC in TG (Thermogravity), a small endothermic peak below 100 oC and a deep endothermic peak from 130 oC in DTA (Differential Thermal Analysis), representing presence of micropore structure of new zeolite species (probability phillipsite). The scanning electron micrograph of the ‘artificial zeolite’ showed spherical structure with chinks formed in the 2,5 M NaOH treatment.

Abstract

Research has been done to evaluate the addition of zeolite to manure fertilizer. This research is aimed to review the advantages and disadvantages of zeolites as manure fertilizer additive. Investigation is carried out by different variables: zeolite particle size, zeolite concentration and curing time. The results show that zeolite particle sizes of –7 +10 mesh and –20 +48 mesh did not significantly different. Zeolite – compost mixture can dry very fast, just in 2 weeks curing time the residual water content is only 5-6%, while that on the controlled compost (without zeolite) is still 70%. Higher zeolite concentration will speed up the compost drying process. On the other hand, zeolite addition will increase the potassium content by 1.7–2% but it also increases NH3 volatilization, which will result in a lower N content. Higher zeolite concentration will give lower N content in the composite. It can be concluded that zeolite addition is suggested not applied to the fresh compost but just before the compost will be used in order to increase the nutrition efficiency.

Abstract

Zeolite is one kind of mining commodity that can be used in feed. Zeolite is used as molecule filter and ion exchange, so the usage of zeolite until certain level will increase protein efficiency and decrease cost efficiency. The main purpose of this research was to compare the effect of zeolite levels (0%, 3%, 6%, and 9%) in feed on the performances of post weaning mice (M. musculus), i.e. dry matter consumption of feed, protein consumption, daily weight gain, feed convertion, water and protein content of feces. Based on the analysis result, the usage of zeolite until 9% was highly significant (P

Abstract

The used of zeolite mineral as soil ameliorant on agricultural had been known since long time ago. Cation exchange capacity (CEC) of zeolite is ≥ 100 cmol(+) kg-1 which regulated on SNI No 13-3494 1994 is a determining quality of zeolite test. However, it is very reasonable to be revised. There are several reason why determining CEC of zeolite on SNI No 13- 3494-1994 must to be revised, because there is an error as possible as on determining CEC of soil. The research aimed to study the measurement of CEC zeolite for agricultural which conducted on five laboratories were (1) Bogor Agricultural University by using stirring (shaking)-sentrifusi decantation methods, (2) Service Soil Laboratory at Indonesian Soil Research Institute by using percolation method that measured by calorimetric auto analyzer, (3) Soil Laboratory at Indonesian Soil Research Institute by using percolation method that measured by spectrometry, (4) PT. Sucofindo, and (5) Research and Development Centre for Mineral and Coal Technology by using percolation method. The result from quality test of CEC zeolite A and zeolite B from five laboratories was significant different, because the difference procedures of the method such as zeolite quality (grade and types), zeolite fineness, and ratio of zeolite to ammonium acetate solution. The criteria of CEC zeolite for agricultural on SNI recommended to be revised on five types are (1) ≥ 100 cmol(+) kg-1(class A); 100 - 80 cmol(+) kg-1 (class B); 80 – 60 cmol(+) kg-1 (class C), 60 – 40 cmol(+) kg-1 (class D), &lt; 40 cmol(+) kg-1 (class E). The result from test of zeolite effectiveness on green house condition showed that distributing of zeolite soil ameliorant could improving grain yield pithy about 19,41% with the average weight of grain pithy with zeolite are 73,30 gram/pot, while without zeolite are 61,22 gram/pot. Giving the combination of ZKK with manure increasing higher the dry weight loose maize is 8,44 tons/ha than without giving the ZKK is 5,65 tons/ha.

Abstract

Bad sanitation environment on student neighborhood area causes the decreasing of ground water quality, whereas the ground water is the main water source of that area. Physical, chemical, and biological parameters showed that the ground water which consumed are contaminated by organic matters from safety tank, ground particles and heavy metal (Fe and Mn). Fe and Mn rates on the well water are 0,0066-0,1657 mg/l dan 0,035-0,072 mg/l. While Fe and Mn ratea on waste water are 0,2193-0,7102 mg/l dan 1,90-4,70 mg/l. Dissolve solid suspention rate on the ground water and domestic waste water are 0,0066-0,1657 mg/l dan 0,035-0,072 mg/l respectively. Chemically, it was below the permitted limit 0,3 mg/l and 0,1 mg/l, but physically the ground water looks coloured, tested and smell. These may be caused by littering and too crowded neighborhood and organic matter intrusion to the well. One of the alternative to decrease the metal rate and dissolve solid suspention on water ground is using zeolite. Ground water analysis showed that zeolite can decreases the Fe and Mn rates from 0,92 ppm to 0,07 ppm and from 0,34 ppm to 0,048 ppm (around 85-90 %).

Abstract

Nitrogen fertilizer is one of the fertilizer type which is required for plant growth. This fertilizer is easily dissolved and the ions are not clay bonded, that it is often washed out by rain, evaporated or changed to other forms which can not be used by plants. In order to increase the efficiency of N-fertilizer, the loss of N must be minimized. In other hand, it is well known that natural zeolites have the capability as adsorbents and cation exchangers, such as for ammonium ion. Investigation has been carried out to analyze the capability of natural zeolite from Cikancra, Tasikmalaya to store ammonium ion from ammonium sulfate fertilizer. This research can be used to predict the quantity of zeolite to be added to the soil if we use ammonium sulfate fertilizer. The natural zeolite applied has been selected of the highest cation exchange capacity (CEC) value zeolite from various particle sizes and activation method. The highest CEC, of 150.92 meq/100g is gained by activation at 105oC of particle size –20 +48 mesh. The optimum CEC of natural zeolite against ammonium sulfate fertilizer is 146.11 meq/100g in 0.2 N (NH4)2SO4 solution. Therefore, the quantity of ammonium sulfate fertilizer (ZA), which can be stored in 100g zeolite is 19.306 g.
