Status of macro and micro nutrients from deposited tailings in reclamation area, PT Freeport Indonesia, Timika S Taberima; R Sarwom
Journal of Degraded and Mining Lands Management Vol 3, No 3 (2016)
Publisher : Brawijaya University

The reclamation program of deposited tailings (SIRSAT) is the obligation of the mining concession holder PT Freeport Indonesia (PTFI). The monitoring of soil and plant qualities regularly is part of the study of the success or performance of mining reclamation. The objective of research in the reclamation area was to study the uptake of macro and micronutrients in inactive tailings, andrepresentative plants that grow up on it. The result showed that pH was alkaline in the land of MP21 with its plants of M. sagoand C.nucifera, MP27 with Matoa (P.pinnata), both of the representative locations with tailings/soil depth of 0-20 cm and 20-40 cm, except the surface layer of MP21 has lower pH, i.e. neutral. The organic matter tends to be higher at MP21 with M. sago, followed by C. nucifera, while at MP27 with P. pinnata was very low on the surface layer (topsoil) and the bottom layer. MP27 was reclaimed in 2003 with P. pinnata, however these plants tend to be abnormal after being planted more than 10 years. While MP21 with M. sago and C. nucifera was more fertile due to high content of organic matter. Besides that, the tailings deposition at MP21 had became inactive tailings for longer, and were used for the land reclamation activities since 1992/1993. The uptake of macronutrients, especially K was high, which was found in both productive and old leaves in the representative plants of inactive tailings and natural soil. While the old leaves of P. pinnata produced the highest content of S, i.e. > 0,1%. Mnwas the highest in both of old leaves of C. nucifera (379,50ppm) and M. Sago(558 ppm) which were planted in the natural soil. These concentration levels were higher than normal criteria (> 300 ppm Mn). The uptake of Zn includes normal criteria, except in the productive leaves (170,67ppm), and also the old leaves (160.33 ppm), or exceeds of the normal criteria (> 100 ppm Zn) found in P. pinnata MP21.

Publisher : Brawijaya University

Increased productivity and the expansion of planting area to potential land are two strategies to increase soybean production. Swamp land is one of potential land. Acidic soil, poor fertility, and toxicity become limiting factors for soybean development in this area. Objective of this research was to determine effect of liming, organic and NPK fertilizer application on soybean yields in swamp land. On-farm trial had been conducted on swamp land of C type in South Kalimantan. Treatments consisted of two factors, laid out in randomized complete block design, replicated three times. The fist factor was three doses of manure (0, 2.5, and 5.0 t/ha). The second factor was four combinations of NPK fertilization dosage, (1) 0-0-0, (2) 22,5-36-30, (3) 22,5-54-60, and (4) 45-72-60 kg N-P2O5-K2O per hectare. Combinations of these two factors were tested on two environments, without and with liming. Results revealed that soil acidity, poor P, K, Ca, and Mg, and high aluminum saturation became limiting factors for soybean growth and yield in swamp land of type C in South Kalimantan. Amelioration using 2.5 t/ha manure, liming with dolomite equivalent to 20% of Al saturation, and NPK fertilizer at dose of 45 kg N - 72 kg K2O – 60 kg P2O5 /ha improved soil properties and soybean growth, and increase productivity to 2.4 t/ha.

N availability in the soil is determined by the rate of mineralization. N mineralization can be estimated using several models. Aim of research is to compare of two kinetics models for estimating N mineralization affected by different inputs of organic matter and soil fertility in Typic Hapludults. Research used completely randomized design with two factors. The first factor was land use : (1). Soil from land cultivated by cassava crops for less than 10 years, and (2). Soil from land cultivated by cassava crops for more than 30 years. The second factor was type of organic matter: (1). Groundnut biomass, (2). Maize biomass, (3). Groundnut-maize biomass, with ratio of 1:1, (4). Groundnut – maize biomass, with ratio of 2:1, (5). Groundnut – maize biomass, with ratio of 1:2, and (6). Without organic matter. The result shows that based on the value of R2, first-order kinetics equation is more suitable to decribe N mineralization than double-pool kinetics equation because R-square value higher than double-pool kinetics and is positively correlated with N mineralization parameters (N0, k and N0.k).

Publisher : Brawijaya University

The hedgerow systems are the agroforestry practices suggesting any positive impacts and negative impacts on soil characteristics. This study evaluated the effects of hedgerows on the unsaturated hydraulic conductivity of soil with the Libardi method approach. This study was conducted in North Lampung for 3 months on the hedgerow plots of Peltophorum dassyrachis (P), Gliricidia sepium (G), and without hedgerow plot (K), with four replications. Each plot was watered as much as 150 liters of water until saturated, then the soil surface were covered with the plastic film. Observation of soil moisture content was done to a depth of 70 cm by the 10 cm intervals. Soil moisture content was measured using the Neutron probe that was calibrated to get the value of volumetric water content. Unsaturated hydraulic conductivity of soil was calculated by using the Libardi Equation. Data were tested using the analysis of variance, the least significant different test (LSD), Duncan Multiple Range Test (DMRT), correlation and regression analysis. The results showed that the hedgerow significantly affected the soil moisture content and unsaturated hydraulic conductivity. Soil moisture content on the hedgerow plots was lower than the control plots. The value of unsaturated hydraulic conductivity in the hedgerow plots was higher than the control plots. Different types of hedgerows affected the soil moisture content and unsaturated hydraulic conductivity. The positive correlation was found between the volumetric soil moisture content and the unsaturated hydraulic conductivity of soil.

West Sumbawa Regencyis one of the regencies that are rich of natural resources managed by PT. Newmont Nusa Tenggara. However, local communities around the gold mine areas have generally to date been poor. This study was aimed to (1) examine the effect of material poverty, physical weakness, isolation, vulnerability, and powerlessness on poverty, and (2) describe the distribution of rural povertybased on land slope mapsin gold mine areas in West Sumbawa Regency.This study applied a survey technique, observation, and structured interviews to collect data. The processing and analysis of data was carried out by a quantitative method using a multiple regression analysis. The results of the study showed that the factors significantly affecting the poverty among rural communities around gold mine areas were material poverty, physical weakness, isolation, vulnerability and powerlessness (R2 = 0.715). However, the mostly dominant factor affecting the poverty was powerlessness (t = 19.715). Meanwhile, the distribution of poverty based on topographic sites showed that the poverty occurred in villages with plain topography (Goa Village), terrain topography (Maluk Village), wave topography (Belo Village), and hilly topography (Sekongkang Bawah Village). The poverties occurred in all the villages were mostly affected by powerlessness with t values of 3.489, 13.921, 11.828, and 6.504, respectively. This condition was due to minimum access and communication by local communities to local government and the gold mining company of PT. Newmont Nusa Tenggara

Publisher : Brawijaya University

The article is devoted to the task today to improve the effectiveness of blasting during construction of horizontal and inclined mine excavations. Construction of new and reconstruction of existing mines requires large volume of excavation works, which length can reach tens of kilometers for only one project. Drilling and blasting workings allow not only to break out rocks from a frontal part of an excavation, but also cause an internal effect, which can lead to undesired damage that, in turn, often lead to increased expenses for excavation operations and safety problems for personnel. Calculation methods for blasting and explosion operations is a topical issue in mining industry as they allow to improve characteristics of excavation works and safety of explosion operations. Dozens of scientists offer their design, which reflects the vision of the problem and its solution. There are many methods for calculating the parameters of drilling and blasting, but so far not developed a uniform methodology of calculation, which would encompass all the factors and explained the mechanism of formation of cracks around the explosive charge and the process of breaking rock. The paper presents a novel methodology for calculations for blasting and explosion operations. That methodology comprises various specifics of rock geology and mining engineering during works in horizontal and vertical excavations. In this paper given an algorithm for calculation two main areas of destruction: crushed zone and fracturing zone. In addition, article outlines main aspects of Mining Engineering Development from Antiquity until present days and presents the dynamic of mineral resources.

Publisher : Brawijaya University

In developing countries including Ethiopia changing pattern of rainfall, increasing temperature, recurrent drought, massive land degradation, and poor performance of agricultural sector contribute for failure to meet the growing demands for food for the rural communities and left dependent on foreign food aid and seasonal migration. This study aims at examining the perceived impacts of climate change and disaster risk management by rural communities in Ethiopia. Cross-sectional socio-economic data were used. Dejen district was purposively selected as it is highly susceptible to climate related problems. Stratified and snowball sampling techniques were employed to select a sample of 398 households. Household survey was employed to collect data on climate change impacts perceived by local communities. Focus group discussions were carried out using guiding questions and seasonal calendar. Key informant interviews were used to triangulate households’ perceived climate change impacts. Field observations were used to observe biophysical, economic, social, and institutional features of the district. The results indicate that crop pests, soil erosion, crop disease, frost, drought, flood, hailstorm, and erratic rainfall were the major contributing factor for the loss of 50,555 quintals of agricultural cops over the period 2009-2016. The community seasonal calendar indicate that erratic rainfall, hailstorm, dry period, flood, landslide, livestock disease, crop disease and pests, and human diseases were the major climatic events in the study areas of rural communities. The lowland households were more susceptible to climate change impacts. Policy priority should be given based on the agro-ecology and households livelihood assets vulnerability levels

The textile industry produces sideline output in the form of dangerous waste. The textile industrial waste containing heavy metal, one of which is Chromium (Cr). Chromium is very dangerous metal for environment, especially chromium hexavalent that has properties of soluble, carcinogenic, and toxic. The pollution of chromium in soil is a problem that the action to be taken with the technology of bioremediation. Phytoremediation of soil contaminated with chromium using Mendong plant (Fimbrystilis globulosa), combined with association of microorganisms Agrobacterium sp I3 and compost. This study was conducted in field experiment plots using a completely randomized block design. Data were analyzed using Anova followed by Duncan and correlation tests. The results showed that the Mendong plant was an effective phytoremediator of soil contaminated with chromium and it can be used as a chromium accumulator plant. The highest decrease of soil chromium content of 58.39% was observed on the combined artificial fertilizer, Agrobacterium sp I3 and Mendong plant treatment (P1B1T1). Removal effectiveness of chromium at the treatments using Mendong plant was higher than without the Mendong plant. Chromium uptake in shoots was higher than in roots of Mendong plant. Bioremediation increased the total bacterial colonies, decreased soil pH, and increased cation exchange capacity of the soil. The growth of the Mendong plant was in a good condition during the process of bioremediation.

Rice productivity is having a problem related with climate change phenomenon, mainly the global warming. The rising of temperature in some country threat the rice production. The increasing of temperature is a major limiting factor that affects yield through the growth and development of rice plant. This study was aimed to examine the response of rice (Oryza sativa L.) to elevated night temperature with the application of Pyraclostobin. A glasshouse experiment that was conducted from March to August 2015 at Brawijaya University Research Station of Jatikerto – Malang, used nested plot design with three replications and two treatments. The first treatments were the night temperature level (normal temperature, increased 2oC, and increased 4oC). The second treatments were the concentration of Pyraclostrobin (0 ppm, 400 ppm and 800 ppm). Results of the study showed that the increase of temperature at night for about 2oC and 4oC, as well as application of Pyraclostrobin, affected growth and yield of rice. Application of Pyraclostrobin by concentrations of 400 ppm and 800 ppm effectively reduced yield loss by increasing night temperature of 2oC, which resulted in 20.20% and 24.93%, respectively, in comparison with the control; while the increase of night temperature by 4oC have resulted 26.86% and 33.33% in comparison with the control. Pyraclostrobin was effective in maintaining percentage of the filled spikelets by the increase of temperature at night for about 2oC and 4oC.
