IOP Conference Series: Materials science and engineering 2021年第1期1143卷

作者： Evi Gravitiani Nuri Resti Chayyani Sunu Herwi Pranolo Prabang Setyono Ary Setyawan Postgraduate Program on Economic and Development Studies Universitas Sebelas Maret Surakarta Indonesia Department of Chemical Engineering Universitas Sebelas Maret Surakarta Indonesia Department of Civil Engineering Universitas Sebelas Maret Surakarta Indonesia Department of Environmental Science Universitas Sebelas Maret Surakarta Indonesia

Indonesia is one of the biggest oil palm producing countries. Solid waste from processing palm oil into crude palm oil (CPO) includes palm shells. This palm shell waste can be used as an alternative to diesel fuel for aggregate heating. This study aims to analyze the investment of the use of palm shells as an asphalt burner replacing diesel. Primary data were obtained from field and laboratory identification. In contrast, secondary data were obtained from relevant agencies, the Department of Public Development and Public Housing, PT Bara Energi Biomass and PT Damai Citra Mandiri. The method used is a quantitative descriptive analysis by calculating the annual costs and benefits over the machine's life, ten years. This study uses the Cost-Benefit Analysis. Four investment criteria are calculated: (1) Net Present Value (NPV), (2) Benefit-Cost Ratio (BCR), (3) Payback period (PbP), (4) Internal rate of return (IRR). The results found that palm shells' use as an asphalt burner for diesel substitutes showed high costs and top benefits. The calculation of economic feasibility with investment criteria shows that the NPV has a positive value, which means it is feasible. BCR shows a ratio of costs and benefits is more than one; it indicates that investment in asphalt production activities is feasible. The calculation of investment in replacing diesel fuel with palm shells shows a positive value of PbP since the first year. The internal rate of return shows that the investment value has met the minimum standard of general interest or replacement.

Recently, there is a new trend to consider wastewater as a precious resource. Since phosphorus is a limited non-renewable element, and MAP (Magnesium Ammonium Phosphate - MgNH4PO4.6H2O) is a valuable slow-release fertilizer, the recovery of phosphorous as MAP has received special attention from scientists all over the world. However, the application of this process with municipal wastewater is still a challenge, due to low concentration of phosphorus and high volume of municipal wastewater. This study investigates the potential of reclaiming MAP from municipal wastewater by combination of adsorption and crystallization. Soybean milk residue (okara) was loaded with Zirconium (Zr) to prepare the adsorbent (ZLO). Adsorption and desorption experiments were conducted in a semi-pilot scale ZLO packed colum system. Effects of P: N: Mg molar ratios, chemical sources and temperature on the formation of MAP were examined in an attempt to identify the optimal crystallization conditions. The attained precipitate was characterized using XRD, SEM, FTIR techniques. It was found that the ZLO packed column adsorption-desorption system could pre-concentrate phosphorus from municipal wastewater up to 28.36 times, fitting well the minimum requirement (50 mg P/L) for the economical MAP recovery. Up to 95.19% of dissolved phosphorus in desorption solution was recovered at pH = 9, Mg: N: P molar ratio = 2:2:1, using a combination of MgCl2.6H2O and NH4Cl. The harvested MAP exhibited high purity (92.59%), high P-availability (89% by mass), and extremely low levels of heavy metals. The results prove that it is viable to recover MAP from municipal wastewater by employing ZLO as adsorbent, followed by crystallization. This paves the way for mining phosphorus from municipal wastewater and reducing okara as an agricultural byproduct in a green way. © 2019 Published under licence by IOP Publishing Ltd.

Economic globalization and population growth have greatly challenged energy, water and land resources to meet demand at national and supra-national level. A growing share of this demand is met through trade. The Belt and Road, a major global initiative of China, with trade as one of its core fields is of particular importance due to greater potential of economic growth, substantial population size and varying degree of resource availability. The initiative reflects a new phase of globalization yet resources management with nexus thinking has received little attention. The increasing economic interdependence of national economies have contributed to rise in production and trade of goods and services, these activities require the input of energy-water-land and generate disturbances in the environment. The multi-regional input-output approach is utilized, to assess resources use by production as well as consumption (for the year 2010). A nexus strength indicator was developed to show the simultaneous use of multiple resources in economic system, conceived as resource nexus. The ternary diagrams were used for screening resources combinations along with *** revealed that China has strong nexus strength that indicates large usage of the three resources together. Besides China, the East European countries were also positioned mostly at the center of ternary plot suggesting somewhat equal contributions of energy, water and land to the resource nexus. On the contrary, countries that appeared at the margins of the plot indicated one or two stronger nexus components in the three resources system. For instance, Russia largely used land, South Korea was entirely driven by energy while India mostly used water in the ternary mix. Due to differences in industrial structure, trade policy priorities and technology use, the resource nexus matters are not the same among countries. The nexus strength indicator established that strong nexus caused by intensive use of e

MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes (IACTs), designed to detect very-high-energy gamma rays, and is operating in stereoscopic mode since 2009 at the Observatorio del Roque de Los Muchachos in La Palma, Spain. In 2018, the prototype IACT of the Large-Sized Telescope (LST-1) for the Cherenkov Telescope Array, a next-generation ground-based gamma-ray observatory, was inaugurated at the same site, at a distance of approximately 100 meters from the MAGIC telescopes. Using joint observations between MAGIC and LST-1, we developed a dedicated analysis pipeline and established the threefold telescope system via software, achieving the highest sensitivity in the northern hemisphere. Based on this enhanced performance, MAGIC and LST-1 have been jointly and regularly observing the Galactic Center, a region of paramount importance and complexity for IACTs. In particular, the gamma-ray emission from the dynamical center of the Milky Way is under debate. Although previous measurements suggested that a supermassive black hole Sagittarius A* plays a primary role, its radiation mechanism remains unclear, mainly due to limited angular resolution and sensitivity. The enhanced sensitivity in our novel approach is thus expected to provide new insights into the question. We here present the current status of the data analysis for the Galactic Center joint MAGIC and LST-1 observations. © Copyright owned by the author(s) under the terms of the Creative Commons.

Mining in the world consists of modern and traditional mining. Various studies have discussed how field workers were precarious at being exposed to Covid-19 in modern mining. Many studies discuss ways of modern mines overcoming Covid-19, but discussion of research related to the impacts of Covid-19 on traditional mining has not been carried out. This study addressed the effect of the Covid-19 pandemic on traditional oil mining in Wonocolo, Bojonegoro Regency. This work is a descriptive study using observation and in-depth interviews and reviewing secondary data related to conventional mining activities. The results showed that the Covid-19 pandemic has an indirect effect on traditional oil mining activities in Wonocolo. The pandemic caused a decrease in demand, a drop in selling prices, lower production, and temporary closure of wells in Wonocolo traditional mining. In contrast, Covid-19 did not directly affect miners' activities since the miners believed that Covid-19 could not infect them due to the very extreme condition in the mining area that the Coronavirus would not survive.

Hydrogen sulfide reduction by conductive concrete with MFCs strain

引用

IOP Conference Series: Materials science and engineering 2020年第1期965卷

作者： M Fukushima K Promunuan S O-Thong T Suzuki T Imai Division of Environmental Engineering Graduate School of Science and Technology for Innovation Yamaguchi University Japan Biotechnology Program Faculty of Science Thaksin University Phatthalung Thailand

The objective of this study is to reduce the production of Hydrogen sulfide (H2S) in sewer pipe by using conductive concrete and electricity-producing bacteria (EPB). This work was mainly focused on evaluating the effect of inoculation of EPB isolated from sewage sludge from municipal wastewater treatment plant for decreasing production of H2S. The experimental results showed that inoculation of EPB could decrease the concentration of H2S, indicating that produced H2S in an anaerobic sludge sediment layer (bottom of sewer pipe) was biologically oxidized by EPB. These results demonstrated that conductive concrete can provide an electron pathway from anaerobic sludge sediment in the bottom of sewer pipe to oxygen dissolved in surface water, and as a result the electron generated from hydrogen H2S oxidation in anaerobic environment was accepted by oxygen via conductive concrete.
