Abstract

Zeolite is a group of hydrated silical alumino mineral from alkaline specially sodium (Na), Potassium (K), Calcium (Ca), and Magnesium (Mg). More then 2000 years since it found the first time by Cronstedt on the year 1756 in Sweden have been found more then 50 type of natural zeolite and 150 type synthetic zeolite. The use of zeolite covers a wide range of field due to its ability as absorber, catalyst and ion exchange. However, the use of natural zeolite have several limitation such as limited source, a very high variation mineral composition, and crystal size, porosity and un uniform pore diameter. On the other hand, synthetic zeolite is created to overcome the difficulty and weaknesses of natural zeolite. Several technological research and development have been carried out to increases the economic value of zeolite by exploitation and modifying zeolite capacity as absorber, catalyst and ion exchanger. Zeolite have been used on agriculture, cosmetics, and other industries.

Abstract

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.

Abstract

The quality of zeolite deposits at some locations are not the same, whereas in its utilizations, such as the utilization for the fertilizer carriers, the standard quality of zeolite should be fulfilled, for instances the cation exchange capacity should have a minimum value of 120 meq/100 gram, particle size should be –10, +48 mesh, the zeolite grade was 50% of the tuff, and the moisture content was 8% in which its referred to the SNI 13-4696-1998, and that for the fowl and cattle food additives, the standard quality of the cation exchange capacity should be minimum value of 160meq/100gram, the particle size of –28,+100 mesh, the zeolite grade 50%, and the moisture content of 5% which is related to SNI 13-4897-1998. Nowadays, there is not all zeolites for the industry utilizations have the standard yet, whereas the each of zeolite used should reach the quality standards. The process to attain the technical specification properties of the standard quality used for the commodity is called standardization. Standardization aspects include the procedures, the technology used, the environmental aspects, and the examinations used to be accurate and accredited. Based on the standard of the technical specifications, zeolites used will then be as commodities with assured qualities.

Abstract

God has given us rain / water as a mercy gift. Why, we are human being make it become a disaster? Why our efforts to overcome floods, pollutions until now, did not give good results yet? Because, the most precious gift has been given by God, free! And often, we can not appreciate something got free. That’s why, we are used, on purpose, to flow the rain water to drainage, small / big river and last, to the sea/ ocean. Natural Zeolites, which are treated physically & chemically (TNZ) can be used succesfully, as media water filter and gas / air (adsorbent) purifier. A certain type of TNZ can neutralize the acid rain and make its void (channel) pores as prisoner for the heavy dangerous metals. If we install the pipe of factory ehimney horizontally (not vertically) and insert the ZA granules in the muffler that way, then we will make our air, fresh and clean. Grey Water which come out from the domestic waste water, will be changed into clear (transparant) clean water, if filtered through TNZ filter bed, while Biolite will change the black water into excellent organic Fertilizer. Biolite is a liquid product, produced from Zeolite powder and probiotic bacterie & additives. The Zeolite powder will adsorb the colour & bad smells and the bacterie will reduce the faeces volume of the Black Water. By using a new (innovative) Domestic Waste Water Treatment Plant (DWWTP) you can easily recycle and reuse the final effluent. Beside this DWWTP will give you excellent organic fertilizer as added value, the investment & operational costs are much reduced & efficient compare to the old (conventional) one. So, you can rely on Zeolite minerals (TNZ, ZA) & its derivat Biolite, not only as soil conditioner, but also to make you sure, that your plants will grow fertile. It is our duty to maintain this Earth, as God create it in a prosperous & equilibrium status.
