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

The research has been conducted to study the effect of adding zeolite to the ration on the production performance of mice (Mus musculus). The litter of the first (LS12) and second (LS2) from the same mice which received rations added with zeolite for a long period of time were used in this experiment. The rations with different level of zeolite ( 0,3, 6 and 9%) were used for male and female experimental mice from LS1 and LS2. Randomized Complete Design (RCD) with two factors, namely level of zeolite and sex, with six replication used in this experiment. The result showed that added zeolite to the ration did not affect feed consumption but significantly increased body weight gain and feed efficiency, reduced water and protein content of feces but significantly increased protein digestibility. Mortality rate in this experiment was very low ( 1.6 – 2.41%). It could be concluded that added zeolite to the ration up to 9% give better performances of the experimental mice.

Abstract

Requirement of refractory materials for manufacturing industry and metal smelting is increasing along technology development. Brass smelting needs a larger size ceramic crucible which is known by the name “kowi”. Therefore, it needed a refractory material from local raw materials are higher quality, which has a low porosity, high density, and high mechanical strength. In this study was conducted increasing refractory quality of alumina silicate as a material for manufacturing a brass smelting kowi by infiltration technique. The raw materials such as kaolin, alumina, and magnesium oxide that has been determinate composition were brooded, printed, half-baked burned, infiltrated with a various concentrations, and then burned again, physical and chemical characteristic testing, and also used a Scanning Electron Microscope (SEM) to show morphology of refractory alumina silicate that have been infiltrated. The result showed that refractory alumina silicate was increase the qualities with porosity value of 11,36%, density value of 2,34 kg/m3, water absorbent of 4,85%, and mechanical strength of 129,072 kg/cm2 which can be used as “kowi” material for brass smelting industry.

Abstract

Zeolite generally have a very high exchange ion capacity and capability to catch ions. Therefore, zeolite is used on agriculture to reduce ion movement around the root zone and to increase the use of fertilizer by plant. A research have been established on 1999/2000 using zeolite from two sites that represent two type of soil, Planosol soil from Jakenan (Pati) and Podsolic soil from Tamanbogo (Lampung).Group randomize design with three repetition is used on this research. Fertilizer treatment on this research are 60-100 % P or K and 0-40% zeolite, 100% P or K + 200- 300% kg/ha zeolite. The final result of this research showed that in order to produce high quality of paddy on podsolic soil need the P fertilizer. The zeolite been given along with P fertilizer worth while to increases efficiency, even though it did not positively increasing yield. Adding 300 kg/ha zeolite can reduce the use of fertilizer around 20% P. The Same thing happened to fertilizer K on planosol. Zeolite plus which enriched by a number of minerals giving a better result compare to the one without enrichment. On greenhouse atmosphere, though dosage of zeolite plus (5-10 t/ha) used to increase exchange ion capacity on soil, producing rice around 11.9 t/ha. But on the field, the production decreases cause by heavier disease attack due to the too crowded plantation and too damp condition around the canopy. This is why it is necessary to give the right zeolite plus dosage, not just to increases efficiency, but also to make it financially reachable by the farmer.

Abstract

Naturally, zeolite is a cation exchanger but this property is also depending on porosity, tetrahedral density and frame density. Cation exchange effectiveness can be changed by structure, Si/Al ratio and effective pore size. Tetrahedral group, T, in zeolite is negative charged and can be substituted isomorphycally by other group like PO2+. The new structure can be functioned as anion or cation exchanger. The exchange capacity of both ions depends on Si/Al/P ratio from the substitution process. The alumina-silicaphosphate (ASP) compound has been made from zeolite from Cikalong, Tasikmalaya, with ammonium dihydrogen phosphate (ADHP) with substitution rate between 30-40%. This product has been tested to Pantura groundwater, in Bekasi and Karawang areas,which have groundwater type of NaCl, CaCl2, MgSO4 and CaCl2/CaSO4. ASP tests on ground water samples show decreasing content of Ca, Mg, Na and K cations in ground water by 32.94%, 3.35%, 2.52% and 23.60% respectively. Sulphate anion also decreases by 15.39% but chloride anion shows no changes. Dig-up well of CaCl2 type also shows a reduction of Ca, Mg, Na and sulphate contents by 46.26%, 18.37%, 16.39% and 10.84%, respectively. Dig-up well of CaSO4 type shows Ca, K and sulphate contents decrease of 89.71%, 33.31% and 5.26%, respectively. CaSO4 dig-up well can be changed to Mg-mix type after processing by ASP compound. Cation exchange capacity of ASP compound to Ca is higher than to K, Mg and Na (Ca>K>Mg>Na). Due to a high cation exchange capacity to K and Mg, ASP compound may be used to reduce the hard water level.
