Abstract

Framework structures of clinoptilolite and mordenite phases in natural zeolit from Bayah have been succesfully analysed using Rietveld Method. The diffraction intensity data were collected using X-Ray Difractometer (XRD) at P3IB-BATAN. The refinement of the clinoptilolite and mordenite phases have been carried out and the results show that there are poly cation K-Mg clinoptilolite phase, with space group symmetry of C2/m No.12, monoclinic crystal system and poly cation Ca-Na mordenite phase, with space group symmetry of Cmcm No.63, orthorombic crystal system. Chemical formulas of clinoptilolite and mordenite phases are (K5,17 Mg0,16) (Al6Si30O72). 24H2O and [(Na 5,63 Ca 1,13) (Al8Si40O96). 22H2O per unit cell respectively. Fitting quality (goodness-of-fit) gave a value of Rwp = 10,34%.

Abstract

Sweet potatoes are more sensitive to fertilization of Nitrogen (N) and Potassium (K), among other macro nutrient elements. Theoretically, in order to produce one ton of this comodity, at least 3 kg N, 9 kg K, and 2 kg P are needed. But in fact actually, urea as a Nitrogen source that might be added to soil commonly evaporated in other way the KCl as the Potassium fertilizer easily leached down from soil profile and thus the plant productivity much lower. Objectives of this research are to study the influence of zeolites addition to increasement of nutrient absorption in soil by Sweet Potatoes. The research was conducted from February - June 2003 in District of Katibung, Jati Agung, Merbau Mataram, then from March-July 2003 in District of Panjang, and April-August 2003 in District of Waway Karya by using Complete Randomized Block Design with 3 replication. Each plot consists of 7 planting area (sized 35 m2) and planting distance is 100 cm x 25 cm, or plant density 140/plot. Zeolites is applied in application level of 30 % from total weight of fertilizer 350 kg/Ha. Bedeng size measure 30 cm and wide 60 cm. Zeolite used with dose 30 % from or equals to 105 kg zeolites/ Ha, Result of crop yield that showed by tuber weight both the small sized or the large sized tuber are optimalized in treatment C which 105 kg/ha zeolite. It could be explained because addition of zeolites in fertilizer increase the nutrient absorption by the crop planted. In all research locations, treatment C yielded the most beneficiary production of Sweet potatoes. Tuber root weight in Chinesse Fertilizing treatment lower than other fertilizer because the nutrients are much slower released in the soil profile.

Abstract

The decrease of hardness (Ca, Mg) and heavy metal (Fe, Mn, Zn) contents in raw water was conducted by flowing the sample water through the activated zeolite bed column. Treated water obtained from the experiment obviously met the parameter in standard requirement of drinking water. Activated natural zeolite from Cikalong, Tasikmalaya is able to decrease the content of Ca, Mg, Fe, and Mn in the sample water through the cation exchange process by percolation method with the optimum flow rate of 5 volume bed/hour on the zeolite with the particle size of -10+18 mesh especially for decreasing the hardness (Ca and Mg content). On the other hand, optimum condition for decreasing Fe and Mn contents are reached on the zeolite with the particle size of -10+18 mesh and water flow rate of 10 volume bed/hour. The final treated water contained 0,08 ppm Mn and 0,024 ppm Zn, meanwhile the hardness and other cations have been reduced below the required limit value (0,30 ppm for Fe, 0,10 ppm for Mn, and 0,05 ppm for Zn).

Abstract

The objective of this research was to study the growth and efficiency of broiler productivity. The research was conducted through the application of zeolite spreading treatment into the broiler housing in Non-ruminant Research Station of Animal Science Laboratory of Papua State University. Study was arranged by Randomized Sample Design with four treatments: P0 (control; without zeolite spreading); P1 (once time spreading during the research period); P3 (three times application of spreading during the research period); and P5 (five times of spreading or once a week during the research period). The application of zeolite spreading was not significantly influenced the rate growth of broiler, though there is a tendency increasing weight gain along with the increased in zeolite spreading level on the litter base. P3 (three times of zeolite spreading during research) produce the feed efficiency of 0.53. Economically, Income Over Feed Chick and Zeolite Cost (IOFCZC) per head per housing unit with the application of zeolite spreading more demand compared to housing units without spreading treatment.

Abstract

Zeolite is one kind of mining commodity that can be used in feed. Zeolite is used as molecule filter and ion exchange, so the usage of zeolite until certain level will increase protein efficiency and decrease cost efficiency. The main purpose of this research was to compare the effect of zeolite levels (0%, 3%, 6%, and 9%) in feed on the performances of post weaning mice (M. musculus), i.e. dry matter consumption of feed, protein consumption, daily weight gain, feed convertion, water and protein content of feces. Based on the analysis result, the usage of zeolite until 9% was highly significant (P

Abstract

Planting media and host crop play an important role in determining inoculum mass production of Mycorrhiza arbuskula (CMA). Planting media used in this research consist of zeolite, sand, and soil and the host crop are S. bicolor, S. splendida, C. javanica, C. pubescens. Host crop S. bicolor could be respectively replaced by S. splendida with zeolite as the best planting media in order to produce mass of CMA. In the other hand, mass production of CMA by the combination of S. splendida and soil as planting media could work well under condition that inoculum added in twofold dosage. Using of P. javanica and C. pubescens with zeolite as a planting media was found as the best combination. And the combination of C. pubescens and soil as a planting media could be used also under condition that inoculum added in twofold dosage.

Abstract

Fertilizer is one of nutrient sources that very important for increasing agricultural production besides improvement of soil properties by application of soil amendments such as zeolites and compost. Addition of zeolites increase the cation exchange capacity (CEC) and fertilizer effeciency while compost used as source organic matter and nutrients in the soil. Estiaty (2005) showed that application of 20 ton/ha zeolite and chicken manure compost 10 ton/ha with basal fertilizers of N, P, K 200 kg/ha respectively is the best dosage for Ipomoea reptans. From the second period showed that there was higher nutrient residue in the soil applied by zeolite and chicken manure compost. These facts were shown from better plant growth and production in the soil applied by zeolite in the second period. The objective of this experiment is to calculate the residue of nutrients from the application of zeolite and chicken manure in the first planting before. The experiment was conducted by application of N, P, and K fertilizers in different rates in the soils after using first planting with zeolite and chicken manure. Ipomoea reptans was used as indicator plant. Experiment was conducted in two stages; first planting such as Estiaty (2005) treatments following by second planting with N, P, K in different dosages. This experiment was conducted in green house of Cikabayan, IPB Darmaga Campus while soil and plant analysis was conducted in the laboratory of Department of Soil Science and Land Management. The result showed that zeolite and chicken manure increase the efficiency of N, P, K fertilizers in the second planting. In the second planting of Ipomoea reptans, the need of N, P, K fertilizers were only half of the first planting with the production of nearly the same. Application of zeolite and chicken manure was not only increase the efficiency of N but also increase the available of P and K in the soil.
