Abstract

Bad sanitation environment on student neighborhood area causes the decreasing of ground water quality, whereas the ground water is the main water source of that area. Physical, chemical, and biological parameters showed that the ground water which consumed are contaminated by organic matters from safety tank, ground particles and heavy metal (Fe and Mn). Fe and Mn rates on the well water are 0,0066-0,1657 mg/l dan 0,035-0,072 mg/l. While Fe and Mn ratea on waste water are 0,2193-0,7102 mg/l dan 1,90-4,70 mg/l. Dissolve solid suspention rate on the ground water and domestic waste water are 0,0066-0,1657 mg/l dan 0,035-0,072 mg/l respectively. Chemically, it was below the permitted limit 0,3 mg/l and 0,1 mg/l, but physically the ground water looks coloured, tested and smell. These may be caused by littering and too crowded neighborhood and organic matter intrusion to the well. One of the alternative to decrease the metal rate and dissolve solid suspention on water ground is using zeolite. Ground water analysis showed that zeolite can decreases the Fe and Mn rates from 0,92 ppm to 0,07 ppm and from 0,34 ppm to 0,048 ppm (around 85-90 %).

Abstract

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.

Abstract

Nowdays, mining and energy are still as important sectors for contributing state economics. However, mining activitis usually make environmental problems because most of mining use open pit mining technique that causing the change for the landscape comprising topography, cover vegetation, hydrology pattern, and distruction of soils. In the consequence, the ecosystem of mining area and its surrounding will disturb. The disturbances will more clear if the overburden containing unstable minerals in oxidize condition (such as pyrite and chalcopyrite) release acid mine drained that disturbing biota growth. Zeolite is aluminosilicate mineral group having unique structure, high cation exchange capacity, porous, and adsorp of ammonium ion and water. With those properties, zeolite can be used as (a) absorp of undesirable elements or compounds such as heavy metals, (b) carrier of nutrients such as ammonium ions, and (c) increasing buffer capasity of soils. This paper will dicuss the prospect of zeolite as material for remediation of abandoned mine land.

Abstract

Indonesia is one of countries which is rich in zeolite deposits. Volcanic activities in this country millions years ago released much of volcanic tuff as source of zeolite materials. The most important of zeolite characteristics are high cation exchange capacity (CEC), capability to absorb ammonium ions, and their unique porous structures. Those characteristics can be used for many utilities of zeolite for agriculture such as soil ameliorant, slow release agent of nitrogen fertilizer, and growth media of horticultural plants. Application of zeolite as soil ameliorant gave good effect if applied in low CEC soil such as Oxisol, Ultisol, and some Inceptisol with high dossage of 10-15 ton/ha. Although zeolites improved the soil characteristics and crop production, only a few farmers used zeolites due to economical reasons. Therefore, other techniques should be developed for stimulating farmers to use zeolites. Application of zeolite with lower dosage can be mixed directly with urea in ratio of 1:1 or 30% if the mixtures are pelletized. Zeolite can be applied in company with other soil ameliorants such as compost, liming, and humic acid.

Abstract

Slow Release Fertilizer (SRF) is a modification fertilizer which aims to improving subtances efficiency on fertilizers by organizing the release slowly or gradually. The methods which used to made a SRF has any variety such as enlarging size, smoothing fertilizer surface, mixing with another difficult soluble materials, and covering fertilizer with certain ingredients so releasing fertilizer under soil more slowly. Some materials can be used as SRF materials are zeolite and humic acid. Zeolite is a silicate mineral which have a high cation exchange capacity (CEC) (varying between 80-180 meq/100g), fit hollow space to ammonium ion size so it have high adsorption capacity to ammonium ion. Meanwhile, humic acid which extracted from inorganic materials has a high CEC too. In this study, urea fertilizer has easily lost characteristics because of leaching and evaporation was conducted by covering zeolite and humic acid. The study aimed to find a proper dosage from combinations of urea, zeolite, and humic acid (UZA) for the paddy and to find proper applications of UZA for paddy. The experiment was conducted in green house with paddy variety Ciherang as an indicator plant. Paddy was fertilized with a standard dosage of N fertilizer from UZA with humic acid value of 0%, 1%, 2%, 3%, 4%, and 5%. UZA fertilizer can improving paddy growth and productivity. UZA fertilizer with 1% humic acid dose is a the best dosage for paddy. The spread distribution of UZA was better than buried on the mud.

Abstract

Although zeolites have been known since the 50s the application of zeolites in Indonesia started in the 80s after promotion by the Mineral Technology Research Centre. Before that period, zeolites were only used as construction materials for wall decoration. Zeolites became popular after publication of zeolite research into many aspects of possible applications. Applications of zeolites are based on their characteristics. Initially natural zeolites were used as fillers in the paper industry, ion exchangers in water treatment, separation of nitrogen and oxygen, sorbents in drying, and construction materials. At the same time, applications of zeolites were developed as feed additives for animals and for water treatment in shrimp ponds. In some countries, zeolites have been used as industrial materials, improvement of agricultural production, and environmental protection. In agriculture, applications of zeolites can be used directly to soils as materials for growth media, mixed with manures during decomposition process, and for mixing with urea as slow release agent. The number of zeolite factories in Indonesia is still low and they produce zeolites in powder and grain forms. In recent years, some zeolite factories have been built to produce zeolites for material of industry, agriculture and environmental protection. The most important effort for zeolite factories is how to produce high quality of zeolite. The prospect of zeolite applications in agriculture is very good as (1) soil amelioration for low cation exchange capacity of soils, (2) material for mixing with fertilizer, (3) material as growth media for horticulture and seedling plantation plants, (4) material for improvement of compost quality, (5) material for water treatment of fish ponds, (6) food additives for animals.

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.

Abstract

Nitrogen is essential nutrient for plants, deficiency of nutrient causes plants could not growth normally. Nitrogen is easily lost from soil so to reduce his lost by forming fertilizers available in slow form (slow release). Some materials can be used to create a slow release of which having high cation exchange capacity (CEC). Zeolite and humic acid are materials which have a highest CEC so it make possible to use as a slow release materials. The study aimed to determine the rate and pattern of nitrogen release from mixture formulas Slow Release Fertilizer (SRF) and urea-zeolite and humic-acid (UZA) and comparing rate of nitrogen release with urea pril. The study conducted in laboratory with incubation experiment during 14th weeks. Determination ammonium and nitrate was conducted by extracting the soil with extractant hydrodistillation 0.1 N HCl + 1 N KCl. The result showed that a higher humic acid concentration was given on fertilizer causes a nitrogen release become ammonium and nitrate more slowly. SRF H5 (urea:zeolit, 70%:30% with humic acid of 5%) have a slowest nitrogen release rate rather than five types of Slow Release Fertilizer (SRF) formulas which containing a humic acid. However, SRF H1 and H3 fertilizer (with humic acid of 1% and 3%) have a most efficiency nitrogen release rate rather than five types of Slow Release Fertilizer (SRF) which is containing a humid acid.

Abstract

Soils in Indonesia are mostly classified as Ultisol having physico-chemical properties such as low pH, low organic matter and very low in nutrients. As a result, the agricultural production on land is very low. Today the use of chemical fertilizers without addition of organic matter to cause a decline in soil organic matter content, soil physical properties become increasingly hard due to structural damage and no development of most soil microorganisms. In such conditions, the soil becomes no more responsive to fertilization so that agricultural production including food crops is leveling of. Therefore, efforts to overcome the barriers of soil properties to increase production of food crops must be done. Recently busy talking people active ingredients that can increase agricultural production spectacular. The material is humic acid extracted from organic materials. The result of this study showed that application of 10 liter/ha humic acid to the soils through zeolite as carrier increased the production of paddy by 15% and corn by 10%. The increase of crop production is due to the development of root then stimulating the absorption of nutrients
