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…

One of the application of zeolite as a multi-function mineral is the use as catalyst. Investigation to utilize Indonesian natural zeolite as a catalyst will increase the added value and gives a chance to reduce the dependency of imported catalyst. One of the main property, which allow zeolite to be used as a catalyst, is a high silica-alumina ratio, where Si/Al >10. As a preminalry stage to form a catalyst zeolite, research has been carried out to increase the Si/Al ratio of natural mordenite from Cikalong, Tasikmalaya. The method applied is dealumination process, which is followed by…

One of the livestock that has potential to be developed in fulfill the meat requirement is the pig. The excellent traits of the pigs are prolific, high carcas percentage (65-80% of live weight), very efficient in converting feed in to the products. Zeolite is a mine commodity that very potential can be used as mineral source in diets. The minerals has specific characteristic which had high absorption and cation exchange capacity. Zeolite can be used in the diets for increasing feed efficiency. The aim of the research was to study the effect of level zeolite from different sources in the diets…

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

Zeolite has been known for improvement of soil fertility through increasing the cation exchange capacity. The objective of this research is to evaluate the application of zeolite for improvement of growth media and growth of oil palm seedling. The research has been conducted in the oil palm seedling research area of Aek Pancur using completely randomized design. The soils used for media are Typic Paleudults, Typic Udipsamments, and Typic Hapludults. The treatment composed of 4 zeolite dossages 0,50, 100, and 150 g/polybag. The results showed that application of zeolite to soils improved the…

The research was carried out to exploit the use of zeolite for phosphate absorption in the water. The result shows absorption of phosphate into 35 mesh Zeolite from Bayah and 5 ml/minutes stream velocity is 78 to 82 % while that into 50 mesh zeolite from Sukabumi and 5 ml/minutes stream velocity is 80 to 87 %. The saturated zeolite can be regenerated by 0,5 N NaOH.
