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…

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.…

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…

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).…

Effect of zeolites spreading on litters to broiler performances under different floor spaces had been performed in five weeks. As many as 324 chicks of a day-old Hubbard strain were fed rations contained 3,000 "“ 3,100 Kcal/Kg ME and 21% crude protein during starter period and fed the ration contained 20% crude protein with similar energy during finisher period. The chicks were randomly allocated to three different floor spaces (10, 12, and 14 heads/m2) and three different zeolites spread-litters (0.0, 2.5, and 5.0 kg zeolites/m2) under completely randomized design with factor 3 x 3 and 3…

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…
