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…

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…

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

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…

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

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…

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…
