Abstract

The use of silica fertilizer still has been included in cultivation technology: however, nutrient status for paddy soil is rarely reported in Indonesia. It is necessary to carry out a research on the determination of nutrient status and the influence of silica fertilizer on rice production. The aims of this research are to investigate the effect trass on soil chemical properties, discover of silica fertilizer on rice production and determine the nutrient status of Si by Cate Nelson and Contiunous Curves. The results showed that the effect of trass has a significant on soil chemical properties such as pH H2O and available Si. The nutrient status of Si was estimated by using several different extractants namely H2O; CaCl2; Ammonium Acetate pH 4.8; and Acetate Buffer pH 4 gives a critical limit value of 13, 17, 34, and 37 mg kg-1, equivalent to 28 mg kg-1, 36 mg kg-1, 73 mg kg-1, and 79 mg kg-1 SiO2, respectively. Meanwhile, the Si availability in the medium class based on Continuous Curves Method extracted by H2O; 0.01 M CaCl2; NH4OAc pH 4.8; and Na-acetate pH 4 were 18-34, 33-41, 44-79, and 42-81 mg SiO2 kg-1, espectively. Burned trass with dose of 10 g kg-1 gives the highest rice production of 44.19 g pot-1 equivalent to 7.07 ton ha-1.

Abstract

APPLICATION OF ELECTROOSMOSIS FOR DEWATERING OF SLUDGE FROM WASTE WATER TREATMENT. Wastewater treatment produces semi-solid residue (sludge) that must be handled carefully during dumping and discharge to avoid polluting the environment. A low cost and easy treatment of dewatering is needed. This research aimed to apply electroosmosis technique for dewatering sludge in order to seek for parameters that can efficiently reduce water content of sludge, including range of voltage, type of electrodes, and distance between electrodes; and to determine the effect of electroosmosis processes on changes of chemical characteristics of sludge. The results showed that: (1) electroosmosis dewatering occurred on the sludge taken from waste water treatment of landfill but not on sludge from water purification plant (PDAM), (2) direct current voltage of 30 volts was the optimum voltage, (3) copper rod cathode provided electroosmosis process as good as stainless steel cathode and both were better than the woven stainless steel cathode, (4) the dewatering time to reduce 1200% (w/w) water content to about 400% was about 40 hours for sludge of 2500 cm3 in volume (laboratory bench scale), (5) the anode need to reinserted gradually approaching the cathode due to current lost when the water content at the anode point reached 400% and sludge at the point shrink, and (6) some chemical elements in the sludge decreased significantly after treatment. Pengolahan limbah cair menghasilkan residu berupa bahan semi padat yang dikenal sebagai sludge. Sludge tersebut juga perlu dikelola penyimpanan dan pembuangannya agar tidak mencemari lingkungan. Salah satu pengelolaan sludge yang perlu dilakukan adalah pengeringan (dewatering). Salahsatu teknik dewatering yang mungkin diterapkan ialah teknik elektroosmosis, yaitu teknik yang memanfaatkan adanya pergerakan air pada media poros di dalam medan istrik searah. Penelitian ini bertujuan untuk mencari parameter sistem dewatering secara elektroosmosis yang dapat menurunkan kadar air sludge paling efisien dan untuk mengetahui pengaruh elektroosmosis terhadap karakteristik kimia sludge. Hasil penelitian menunjukkan bahwa: (1) pengeringan sludge terjadi pada jenis sludge IPAL TPA namun tidak pada jenis lumpur PDAM; (2) tegangan listrik searah sekitar 30 volt merupakan tegangan optimum; (3) katoda batang tembaga menghasilkan proses elektroosmosis yang sebanding katoda batang stainless steel dan lebih baik dibanding katoda stainless steel anyam; (4) waktu pengeringan dari kadar air awal 1200% (b/b) hingga kadar air akhir sekitar 400% untuk volume sludge 2500 cm3 (skala laboratorium) sekitar 40 jam; (5) anoda perlu dipindahkan secara bertahap mendekati katoda karena arus terputus pada saat sludge di titik anoda mencapai kadar air sekitar 400% dan mengalami pengerutan; dan (6) kadar beberapa unsur kimia dalam sludge menurun secara signifikan setelah perlakuan.

Abstract

Productions of crude palm oil (CPO) produce waste which include the empty oil palm fruit bunch (EOPFB), palm oil mill effluent, shells, and fiber. The combustions of shell and fiber as boiler feed produce waste in the form of boiler ash. Boiler ash is very potential to use as an additive to improve quality of the EOPFB compost. The objectives of this research were to study : 1) effect of boiler ash on the quality of the EOPFB compost, 2) effect of  EOPFB compost on the chemical properties of Ultisol, and the yield of mustard. The first experiment was about quality improvement of compost from EOPFB by the addition of boiler ash. The treatments applied were four dose levels of boiler ash: K1= 0%, K2 = 15%, K3 = 25%, and K4 = 35%. The second experiment was greenhouse pot experiment. This experiment was consisted of thirteen treatments with three replications arranged in completely randomized design (CRD). The treatments applied were: four types of compost from the first experimental results aplied to the soil with four dose levels, i.e : 0, 10, 20 and 30 Mg ha-1. The results showed that the addition of boiler ash at the beginning of the composting process improved the quality of  the EOPFB compost: which increased pH, amount of humic acids, macro and micro nutrients content and decreased content of Pb. The aplication of all compost –K1, K2, K3, K4– to Ultisol increased pH H2O, P2O5, organic-C, total-N, exchangeable-Ca, exchangeable-K and yield of mustard and decreased  exchangeable-H, exchangeable-Al. Moreover the yield of mustard was increased about 84% (33.9 g plant-1) with K4 at doses 20 Mg ha-1 and 85% (34.1 g plant-1) with K3 at doses 10 Mg ha-1.

Abstract

Coal ash and humic substances can be used as soil ameliorant in the reclamation of formerly mined land. Due to its high pH and nutrients content, coal ash can be used to improve the chemical properties of the soil, such as increasing of pH, and increasing the levels of nutrients availability in the soil. Humic substances may also be used to complement, as they can increase the release of nutrients from the coal ash. Thus, the objective of this study was to assess the influence of coal ash and humic substances on soil chemical characteristics, nutrient absorption, and plant growth. This study was conducted in two locations - in a nursery area, involving two treatment factors: coal ash at different dosages (0, 200, and 400 g polybag-1), and humic material also at varying dosages (0, 0.04, and 0.08 g C polybag-1); and in a post-mining field using similar treatments: coal ash dosage (0, 2.5, and 5.0 kg planting-1 hole) and humic material dosage (0, 0.56, and 1.12 g C planting hole-1). The results showed that coal ash and humic materials significantly increased the soil pH, available P, and exchangeable K, Ca and Mg. Coal ash also contained a number of heavy metals but in quantities that are far below the limits set by both Indonesian Government Regulation and the US Environmental Protection Agency (USEPA). The above soil amelioration effects mean that. applicaton of coal ash and humic substances can significantly increase the growth of Jabon trees in the reclaimed post-mining land.[How to Cite: Ade MO, Sudarsono, Iskandar and DT Suryaningtyas. 2014.

Abstract

This research was aimed to determine the differences of physical and chemical characteristics from three natural zeolites from Tasikmalaya, Bayah and Lampung areas and to examine the characteristics of the natural zeolite adsorption capability to the micro-nutrients. The zeolite characterization analysis included some variables i.e. mineral types, morphologyand pH, CEC (Cation Exchange Capacity), BSP (Base Saturation Point), Cu and Zn content of zeolite.  Analysis of natural zeolite adsorption characteristics were done by Batch System. Data interpretation were done by  using the isothermal adsorption equation of Langmuir, Freundlich and Brunauer-Emmett-Teller (BET).The results showed that zeolite from Bayah and Tasikmalaya had a similiar morphology and it was categorized as mordenite types and platy structure, while zeolite from Lampung was a clinoptilolite type and tabular structure. The CEC of Tasikmalaya zeolite (137.58 cmol(-)kg-1) was higher than Bayah (96.75 cmol(-)kg-1) and Lampung (87.72 cmol(-)kg-1). Adsorption capability at the Langmuir equation of Cu by Bayah zeolite (47.619 mg g-1) was higher than Lampung (33.333 mgg-1) and Tasikmalaya (28.571 mg g-1). Effective adsorption of Zn by Bayah zeolite 19.417 mg g-1 was higher than  Lampung (16.949 mg g-1) and Tasikmalaya (1.395 mg g-1).

Abstract

 Topsoil in post-mined land generally has a low fertility level. Its availability is not always in sufficient quantities to meet minimal needs for mine reclamation, so substitute materials and ameliorants are needed to increase its quantity and quality. Fine coal and fly ash-bottom ash (FABA) are wastes expected to reduce the demand for topsoil and, at the same time, may improve topsoil quality. This study aimed to examine the application of fine coal as a topsoil substitution and its effect on changes in the chemical properties of topsoil and the growth of jabonv (Anthocephalus chinensis). The study was conducted in a greenhouse with a completely randomized design model with two factors. The first factor was fine coal with four levels of 0, 10, 20, and 50% from the topsoil (w/w), and the second factor was FABA with three levels of 0, 500, 1000 g/15 kg of growing media. The jabon plant was grown for 24 weeks. The results showed that up to 50% fine coal could be used as a topsoil substitution. The interaction of fine coal and FABA increase pH, organic C, total N, cation exchange capacity, available P, base saturation, exchangeable cations, and micronutrients, and reduce the amount of exchangeable Al in the soil. FABA with a dose of 1000 g/15 kg of growing media and 50% fine coal was the best treatment to increase the growth of the jabon plant.

Abstract

Nitrogen (N) and potassium (K) are macronutrients that plants need for better growth and yield. However, they are readily lost from the soil through volatilization, denitrification, and leaching, aside from being absorbed by plant roots. Thus, a Controlled Release Fertilizer (CRF) may be formulated and applied to maximize the beneficial effects of N and K fertilization. This study aimed to describe the release pattern of ammonium nitrogen (NH4 -N), nitrate nitrogen (NO3 -N), and K from CRF through the laboratory incubation method. Two types of CRF - CRF A (16-16-16) and CRF B (30-6-8), with a non-CRF (Mutiara NPK16-16-16) as Control – were used. Each fertilizer was tested at 600 and 1200 kg ha-1 doses. The results showed that the NH4 -N release was very high at 40 – 60% but declined to almost 0% after 14 weeks. The NO3 -N release rate was 17 – 40% during the first week, followed by a steady increase to nearly 100% by the 14th incubation week. Potassium release ranged from 20% to 30% in the first week, then rose to 30 – 70% at Week 14. Overall, CRF (30-6-8) at a dose of 1200 kg ha-1 showed the slowest rate of nitrogen release.

Abstract

Bauxite is one of the most mined minerals in the world and plays an important role as a raw material for aluminum production. The implementation of bauxite downstream policy has an impact on the expansion of bauxite mining area and bauxite post-mining land. The expansion of mining activities can cause an increase in the impact of environmental damage, one of which is the emergence of critical land in post-mining areas. Bauxite post-mining land often experiences problems with soil physical and chemical properties, which cause soil unable to support growth and fulfill plant nutrition needs. Alternatives that can be implemented is the use of adaptive plant seedball and Fly Ash-Bottom Ash (FABA) enriched compost utilization as ameliorant material. Post-mining land reclamation technology is the key to achieve successful reclamation and support the optimization of sustainable bauxite downstream programs in Indonesia.
