Abstract

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 70%. Higher zeolite concentration will speed up the compost drying process. On the other hand, zeolite addition will increase the potassium content by 1.7"“2% but it also increases NH3 volatilization, which will result in a lower N content. Higher zeolite concentration will give lower N content in the composite. It can be concluded that zeolite addition is suggested not applied to the fresh compost but just before the compost will be used in order to increase the nutrition efficiency.

Abstract

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 on pigs growing-finishing periode. The result showed that the used 6% zeolite level had significant effect on average daily gain and optimal point level used is 4,8%. There were no significant effect of zeolite sources on pig performance. Generally the performance of pigs received feed containing zeolite from L better compared others sources (B,S and N).

Abstract

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 calcinations and ion exchange. This process is expected to modify the Na-zeolite from natural mordenit to be a NH4-zeolite which can be transformed to a catalyst zeolite. Dealumination process is carried out using HNO3, with variable concentration and time at temperature of 85°C. Thereafter, zeolite is calcined at 700°C and is followed ion exchange process using NH4NO3. The current stage of research has been succeeded to increase the Si/Al ratio of natural mordenite from Si/Al @ 5 to Si/Al > 10. The process condition applied is dealumination with 8N HNO3 for 24 hours at 85°°C and is followed by calcinations at 700°C for 2 hours. Ion exchange is proceeded with 5% NH4NO3 for 2 hours and is followed by another calcinations at 400°C for 2 hours.

Abstract

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 properties of soils, especially cation exchange capacity. Application of zeolite as soil amelioration in the seedling of oil palm did not significantly improve the growth and absorption of nutrients during 11 months. In general, application of zeolite with the dosage of 100 g/polybag improve the growth and absorbtion of nutrients compared to without zeolite application. On the othe hand, application of 150 g zeolite/polybag decrease the growth and absorbtion of nutrients.

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.

Abstract

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.
