To make it worst, the food security depends on synthetic fertilizer in which the raw materials are derived from fossil materials, i.e., natural gas to produce synthesis gas (syngas) via steam reforming.
There are some materials that could be utilized as sorbent for ammonium such as activated carbon and zeolites.
Natural zeolites are low cost materials that can be easily founded throughout the world.
Material and Methods 2.1 Materials and chemical reagents The natural zeolites were collected from the sedimentary bed in Pasir Gombong, Bayah, Indonesia.

Different operating materials result in the different load amplitudes and periods.
The three main types of operating materials are shown as follows. (1) Large block materials, such as large pieces of ore, large stones on quarry or construction site, are of characteristics of wide range of size variation, irregular shape and uneven density.
The load changes vehemently. (2) Dense materials, such as primary soil, cement, clay on construction site, are uniform texture.
During the test of typical working conditions, block materials, dense materials and loose materials are respectively represented by the rock, the primary soil and loose soil.
The field, materials and driving operation of this test are supposed to be ideal cases.

The increasing demand, mainly from the automobile industry, for materials which combine high strength, high ductility and low specific weight makes steels with the TWIP (TWinning Induced Plasticity) effect a promising material to meet these requirements.
There are several investigations of materials like aluminum, copper and some steel for which k values of about 1 have been found [8,10].
