<![CDATA[The research was conducted at laboratory of 2nd Crop Production, Lampung State Polytechnic using water added to zeolit in rubber processing and crumb rubber quality testing in PKST Kedaton. PTP Nusantara VII. The most important things in crumb rubber processing are water utilizing in latex dilution. Using lot of water in latex dilution can be straight away on rubber quality such as colour index, PRI, ash content, and dinginess content. The experiment was conducted on factorial method with completely randomized block design consist of two factors (4 x 5 with 3 replications. The first factor is water application (A) with A1 = well deep water, A2 = river water, A3 = fond water and A4 = latex serum. The second factors is dosage of zeolit (Z) with Z0 = without zeolit, Z1 = 2, 50%, Z2 = 5.00%, Z3 =10.00% and Z4 = 15.00% on water dilution. The result of the experiment showed that zeolit can increase pH and DHL of water, and rubber weight, but no effect on dinginess content, PO/PRI, and volatile matter. Zeolit application until 10.00% on latex serum can maintain the colour value of rubber and the other quality was not shown any different.]]>

<![CDATA[Seawater contains large amounts of cations. Since this resource is abundant and cheap, it can be a laudable source of plant nutrients. The objective of this study was to investigate the extent to which zeolite could sorb and desorb nutrients in different concentrations of seawater. Results indicated that Zeolite sorbed Na and Mg. The highest percentage of Na and Mg sorbed was 76.19 and 36.69%, respectively obtained for 10% seawater. The desorption study indicated that the higher the seawater concentration used during the sorption, the higher the Na and Mg desorbed. Passing diluted seawater through zeolite leached out K and Ca to the extent that the effluent was concentrated with the cations. This by-product solution can be used as a source of plant nutrients. However, high concentration of such cations in the solution caused high pH and EC, which means that the solution has to be diluted to meet the requirements of plants.]]>

<![CDATA[The aim of this experiment was to find the effect of supplementation of zeolit and was to find the optimum level of zeolit in rations on quail performance. This experiment used 80 female Coturnix coturnix japonica of five weeks old with average body weight 145,44 ± 6,72 g (cv 4,62%). The data were analysed using Completely Randomized Design and polinomial ortogonal test. The treatments was divided to four supplementation zeolit rations treatment (0%,2%,4%,6%). Each treatment had five replication and each replication used four quails. Results of this study indicated that supplementation of zeolit (0 - 6%) in rations gave not significantly different (P ≥ 0,05) to feed consumption but gave significantly different (P < 0,05) to hen day egg production (Ŷ = 46,48 + 4,86X "“ 1,09 X2; 0≤ X ≤6; R2 = 0,90) and significnatly different (P < 0,05) to feed convertion (Ŷ= 4,85-0,44 + 0,10X 2; 0≤X≤6;R2 = 0,97). Level supplementation zeolit 2,22% was optimum to hen day egg production (51,86%) and level supplementation zeolit 2,09% was optimum to feed convertion (4,39).]]>

<![CDATA[Some natural zeolite types have been exploited for long time to improve the quality of mine waste water. This research was to study the effect of natural zeolite from Lampung (Indonesia) to improve the quality of acid mine drainage from gold-mine in South Sumatra. The size of zeolite is 0,045-0,090 mm and it consist of the clinoptilolite, type. The zeolite column was made from PVC pipe with the length of 20 cm and the diameter of 10,2 cm. The zeolite column was leached in saturated condition during 12 weeks and was divided into four times intake of leached samples. Waste mine water taken from the location of Barisan Tropical Mining (Rawas gold project, Indonesia) on 21 and 23 July 1998. The water samples from pit Berenai contain relatively high iron ( 28 mg/l) and mangan of 9 mg/l, while zinc is less than 2 mg/l. The water generally very acid (pH 2,9) and contained the sulphate until 250 mg/l and the value of salinity of 28 mS/cm. The water sample from sediment pond and mining river generally contained iron, mangan and zinc lower compared to Berenai pit. Leached through zeolite column in the end of experiment contained of iron less than 1 mg/l, while manganese only a little changing. For water sample from Berenai pit, the column of zeolite reduced the sulphate content become 66 mg/l, decreased the salinity to less than 18 mS/cm, and increased the pH to 6,5 or more. The results indicated that natural zeolite from Lampung can be used to improve the quality of acid mine drainage. However, the application of the zeolite for larger scale still need detailed study.]]>

<![CDATA[Fresh or clean water is a primary need in housing life. Clean water is used in all housing activities starting from daily needs, they are food and drink; healthy needs for example taking a bath, washing and so on, it is included non primary needs for instance watering plant, washing motorcycle or car and etc. By Increasing population growth, housing need is higher so that many simple housing like Rumah Sangat Sederhana, RSS are established in suburb. Sometimes the location of housing is landfill of swam or field area. In Fulfilment of clean water, developer usually establish shallow well. For example Gelora Persada Housing, Rajabasa, Bandar Lampung. The quality of shallow well in farmer swam or field usually have high organic content that produce bad taste and smell, high turbidity, acid (low pH), and contain high iron (Fe) element. In research was conducted in shallow well of Gelora Persada Housing, Rajabasa, Bandar lampung by using rapid sand filter wich is completed by active carbon and zeolite as adsorbance so that gained to decrease turbidity level from 23,9 NTU become 6,51 NTU; can increase pH value from 6,24 to 6,44 and it also can decrease iron (Fe) content from 3,04 mg/lt become 0,74 mg/lt.]]>

<![CDATA[Gold mining is one of the important mining in Indonesia, besides the mining of coal, nickel, copper, etc. Gold mining in Pongkor (PT Antam) applied deep mining system. Besides producing gold as the main product, mining activity also produces waste in the form of tailing obtained from its processing. Tailing is mining residue, whose gold and silver contents have been extracted, and the tailing has somewhat inferior chemical properties if returned to nature as planting media. Organic matter and zeolite are known as ameliorant which may be used as materials for improving physical and chemical properties of tailings. The objectives of this research were to study the effects of zeolite and compost application on the chemical properties of tailing, growth of sengon plants, and absorption of lead (Pb) by plants. Zeolite with the dosages of 0%, 10%, 20% and 30%; and compost with dosages of 0%, 10%, and 20% were added to tailings then used for planting seedling of sengon (Paraserianthes falcataria L. Nielsen). The results showed that tailing from gold mining of Pongkor had neutral pH values; high content of Ca and Pb; but very low CEC, organic-C, total- N, and bases other than Ca. Addition of zeolite and compost improve the chemical properties of tailing for growing plants. Zeolite had effect in increasing CEC, K and Ca; where as compost had effect in increasing all nutrient elements. Addition of zeolite and compost increased the height, diameter and crown width of sengon plants observed, although did not show significant effect (at α level of 5%), and was able to reduce Pb absorption in root and plant crown.]]>

<![CDATA[To determine the growth seeds of Dendrobium plant with mixture application media of coconut coir, fern, zeolite, and liquid fertilizer supplement have been done by the research in greenhouse Agricultural Faculty, University of Lampung. The treatment was arranged in a 2x5 factorial. The treatment was arranged in Randomized Perfect Design Group, with three replications. The first factor is mixture of growth media: coconut coir and fern (m1); coconut coir, fers, and zeolite (m2). The second factor is the application of liquid fertilizer supplement Hortigro Green with 5 levels of concentration: 0.5 g l-1 (h1); 1 g l-1 (h2), 1.5 g l-1 (h3), 2 g l-1 (h4); and 2.5 g l-1 (h5). The results showed that the mixture media of coconut coir, fern, and zeolite is producing bulb Dendrobium higher of 1,15 cm (16,39%) than without giving zeolite. Application of Hortigro fertilizer until 2,5 g l-1 still increasing the bulb height, leaf number, and length of the top three leaves of Dendrobium linearly. Application of Hortigro fertilizer every 1 g l-1 on a mixture media of growth with zeolite increasing the length of the top three leaves of 0.49 cm while in mixture growing of media without zeolite was increasing the length top three leaves of 1.63 cm. Application of zeolite in a mixture growing media was producing root structure better than the application without zeolite (Fig. 4).]]>
