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

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Cikalong mordenit natural zeolite with the average of cation exchange capacity (CEC) 154,2 meq/100 g has been used on modification trial. This modification attempts to increases the rate of anions absorbtion of zeolite in solution. On this research, zeolite is modificated using HDTMA through stirring process on beaker glass. Before the modification start, zeolite is set on pH 5 using sodium acetate solution. Variables on this research are: zeolite size (–10+18 mesh, -18+28 mesh, and –28+48 mesh), and HDTMA dosage (50%, 100%, and 200%). Furthermore modification of zeolite is tested it’s suphaate and chromate ions absorbtion rate. The modification of zeolite showed that the range of HDTMA weight percent that covers the surface of zeolite is 4,21 – 13,49% with the range of exchange ion capacity rate 137,05 – 143,00 meq/100 g. The best result of the absorbtion rate test is the -28 + 48 mesh zeolite with HDTMA dosage 200% for 49,46 mg/100g (5,15 mmol/kg) sulphate and for the cromat ion on -10 + 18 mesh zeolite with 50% HDTMA dosage, the absorbtion rate is 61,05 mg/100g (6,36 mmol/kg).

Abstract

Investigation has been done for chilli (keriting and hot beauty type) preservation using natural silicate (zeolite). Zeolite from Cikancra (mordenite and clinoptilolite type is prepared in various particle sizes and activated at different temperatures. The activated zeolite is tested for its ability to absorb water. It is found that zeolite with particle size of -100 +140 mesh and activated at 400ºC has the highest capability for water absorption. This zeolite is then used in the preservation tests. Zeolite can extend the preservation of chillies up to 18 days for ‘hot beauty’ type and 23 days for ‘keriting’ type. Vitamin C plus (Vit.C + organics) content of chillies after preservation is also increased to 378.29 mg/100g (keriting) and 606.87 mg/100g for hot beauty. During preservation period, pH of hot beauty chilli is constant while pH of keriting chilli is decreased from 5.66 to 5.39. Carbohydrate content is increased for keriting chilli from 2.18% to 2.33% but it is decreased for hot beauty chilli from 2.77% to 2.01%. Total soluble solid (TSS) content of both chillies is decreased to below 0.95%. Water content of fresh chillies, for keriting type is 79.73% and for hot beauty type is 88.40%. Unexpectedly, fungi’s are formed in small parts of chillies during preservation. However, in general, the preservation tests in closed system have produced fresh chillies with high nutrition content.
