Combined injury: irradiation with skin or bone wounds in rodent models
Authors: Glowacki Julie , Epperly Michael W , Bellare Anuj , Wipf Peter , Greenberger Joel S 
Published: July 2021

Abstract
A radiation combined injury is defined as an injury that occurs in the setting of irradiation, such as those expected after a nuclear accident, radiation dispersal device release (a ‘dirty bomb’), or a nuclear weapon detonation. There is much research on irradiation-associated burns and their healing, but there is less known about other injuries sustained in the context of irradiation. Animal models are limited in their correlations to clinical situations but can support research on specific questions about injuries and their healing. Mouse models of irradiation with skin or bone wounds are validated as highly reproducible and quantitative. They show dose-dependent impairment of wound healing, with later recovery. Irradiation-induced delay of bone wound healing was mitigated to different extents by single doses of gramicidin S-nitroxide JP4-039, a plasmid expressing manganese superoxide dismutase, amifostine/WR2721, or the bifunctional sulfoxide MMS-350. These models should be useful for research on mechanisms of radiation dermal and osseous damage and for further development of new radioprotectors. They also provide information of potential relevance to the effects of clinical radiation therapies.
Sensitivity enhancement via vacuum squeezed injection in Advanced Virgo
Authors: Angelo B D’ 
Published: July 2021

Abstract
Modern gravitational-wave astronomy is based on the Michelson interferometer design, for which a key towards enhancement of the sensitivity is to reduce the noise which arises from different sources. As it was first proposed by Caves, injected squeezed states can be used to reduce the measurement shot noise, thus improving the sensitivity in the high-frequency band. This result was achieved with the German-British interferometer GEO600 in Hannover, and Advanced Virgo joined the third observational run on April 2019 with its operating source of squeezed vacuum producing an improvement in the high-frequency sensitivity up to 3 dB (the horizon for a Binary-Neutron Star detection increases by 2-4 Mpc).

Published: July 2021

Abstract

Bacillus cereus isolated from different food sources. The diarrheal toxin genes such as cytK, hemolytic enterotoxin (hblA, hblC and hblD), non-hemolytic enterotoxin (nheA, nheB and nheC), bceT and entFM in addition to emetic toxin gene were detected by PCR. The cyt K gene was observed in 94.87 % of the isolates. entFM and emetic toxin gene were found very rare in all food samples at the percentage 2.56% and 7.69% respectively. Uncooked rice which has a highest number of bacterial isolation, also showed relatively high percentage of the cytK and bceT genes (90%). These two genes present in 100% of Bacillus cereus isolates in most food samples. Bacteria isolated from burger meat contain all investigated genes.
Automated supplier risk evaluation system

Published: July 2021

Abstract
One key aspect in the manufacturing process is the monitoring of the third-party suppliers, a potential disruption in this component would have an impact on the whole chain of manufacturing and potentially have risks in monetary aspects and reputation loss. Even though stated by contract delivery dates and the quality of the delivery content might vary in between shipments even with well-established providers due to technological changes of changes in the quality process. To minimize this risk and to partially take out the subjective human factor, the current paper proposes the implementation of an impartial observer system that based upon a set of key performance indicators will assign a trust rating to each third party. With the option of both human and machine input, the system can be used as an indicator of how reliable the business with a certain entity is and if the risks would be acceptable for a better price offer.

AbstractIn recent years,Arenga Pinnatafibre has been found with great potential to be used as fibre reinforcement in material matrix composites. This study investigates the effect of fibre contents toward manufacturing defects and interfacial adhesion ofArenga Pinnatafibre reinforced Fiberglass/Kevlar hybrid composite material in boat construction. The composite testing coupons were prepared based on the volume fraction ofArenga Pinnatafibre which are 30%, 45%, 60%, and 75%. The long Arenga Pinnata fibre was placed and arranged into the mould by hand lay-up technique. The testing coupon have been arranged with a thickness of 5mm. Manufacturing defects and interfacial adhesion had determined by Scanning Electron Microscopy (SEM) techniques. The SEM results showed that specimen D (60%) of Arenga Pinnata exhibits the less manufacturing defects with a good interfacial and well bonding between the fibre and matrix among other testing specimens. Meanwhile, specimen E (75%) shows the highest manufacturing defects. As a conclusion, 60% ofArenga Pinnatafibre contents showed less manufacturing defects and exhibited good interfacial adhesion. SEM had significantly determined the manufacturing defects and interfacial adhesion ofArenga Pinnatafibre reinforced Fiberglass/ Kevlar hybrid composite material.

Published: July 2021

Abstract
Parts machined by high cutting speeds can often exhibit high fatigue strength, increased micro-hardness in the surface layers and plastic deformations, due to the tool cutting edge radius associated with the induced stresses. The changing of rake and clearance angles has an important influence on the chip formation, cutting forces, residual stresses, temperatures in both the workpiece and the tool. International research on the influence of geometric parameters of the tool on the entire cutting process, are of particular importance to understand this process development. The approach of this study, considers the parametric realization of the cutting tool profile - a coated TiC turning chisel, which will be used in the finite element simulation of the orthogonal turning process. Deform 2D application, which is a powerful simulation engine was chosen and allows the correct simulation of the cutting process in real machining conditions. Deform 2D enables the automatically meshing and remeshing generation and also the optimization whenever needed and wherever is required a high accuracy, thereby reducing the overall difficulty of the problem and the computational requirements. Using Lagrangian discretization, the machining process was simulated and made possible to observe and present a series of conclusions and own points of view regarding the temperature distribution at the tool tip and in the workpiece, the effective stresses distribution and the cutting force variation under the rake and clearance angles influences.

Abstract
Soil respiration (i.e. from soils and roots) provides one of the largest global fluxes of carbon dioxide (CO2) to the atmosphere and is likely to increase with warming, yet the magnitude of soil respiration from rapidly thawing Arctic-boreal regions is not well understood. To address this knowledge gap, we first compiled a new CO2 flux database for permafrost-affected tundra and boreal ecosystems in Alaska and Northwest Canada. We then used the CO2 database, multi-sensor satellite imagery, and random forest models to assess the regional magnitude of soil respiration. The flux database includes a new Soil Respiration Station network of chamber-based fluxes, and fluxes from eddy covariance towers. Our site-level data, spanning September 2016 to August 2017, revealed that the largest soil respiration emissions occurred during the summer (June–August) and that summer fluxes were higher in boreal sites (1.87 ± 0.67 g CO2–C m−2 d−1) relative to tundra (0.94 ± 0.4 g CO2–C m−2 d−1). We also observed considerable emissions (boreal: 0.24 ± 0.2 g CO2–C m−2 d−1; tundra: 0.18 ± 0.16 g CO2–C m−2 d−1) from soils during the winter (November–March) despite frozen surface conditions. Our model estimates indicated an annual region-wide loss from soil respiration of 591 ± 120 Tg CO2–C during the 2016–2017 period. Summer months contributed to 58% of the regional soil respiration, winter months contributed to 15%, and the shoulder months contributed to 27%. In total, soil respiration offset 54% of annual gross primary productivity (GPP) across the study domain. We also found that in tundra environments, transitional tundra/boreal ecotones, and in landscapes recently affected by fire, soil respiration often exceeded GPP, resulting in a net annual source of CO2 to the atmosphere. As this region continues to warm, soil respiration may increasingly offset GPP, further amplifying global climate change.

AbstractThrixspermumis an orchid that has the characteristics of a very short flowering period. This is one of the obstacles in the conventional identification process that uses morphology, both vegetative and generative. For this reason, a molecular approach is needed as an alternative identification tool for theThrixspermumorchid. For molecular identification, CBOL recommends three markers, namelymatK, rbcL, andITS. In this study, onlyITS2was used sinceITShave been reported for its ability to discriminate plant sample up to species levels. The genomic DNA ofT. longipilosumwas isolated using the CTAB method with minor modification, then used as a template in PCR amplification. The amplicon resulted from the PCR reaction (± 450 bp in size) was purified and further determined using DNA sequencer. The results showed thatT. longipilosumhas a high homology level with its close relatives (per ident 94.07%-96.91%). From alignment analysis, theITS2sequence ofT. longipilosumshowing differences nucleotides located in sequences 3 (A→G), 55 (G/A→T), and 64 (A→G). Meanwhile, phylogenetic analysis showed thatT. longipilosumformed one cluster withT. linusii. This shows thatITS2are highly recommended as a molecular marker to determine the barcode of theT. longipilosum.

Published: July 2021

Abstract
Domestic wastewater is the primary source of river pollution. Every human activity in the house must produce waste. Domestic wastewater from the kitchen, bathing, and washing activities contains organic pollutants. The parameter tested was ammonia. In this study, Multi Soil Layering (MSL) was used as a processing method. This treatment serves to reduce ammonia levels in wastewater. This study aims to determine the removal of ammonia in greywater using the Multi Soil Layering System. Wastewater samples were taken in a residential area of Semarang. In this study, there are 2 stages, namely the preparation and implementation stages. In the seeding and acclimatization process, a batch reactor was used for 14-24 days running. The next stage is the process of running for 20 days with intermittent flow. Soil Mixture Box (SMB) is a mixture of andosol soil and activated charcoal (reactor A), andosol soil and apus bamboo (reactor B), and andosol soil, activated charcoal, and apus bamboo (reactor C). The results of domestic wastewater treatment using the MSL method respectively in the three reactors can remove ammonia by 49%, 51%, and 52%.

Authors: Nadiroh N , Zulfa V , Yuliani S 
Published: July 2021

Abstract
The 6 C’s for the 21st century play an essential role in developing an independent learning curriculum in Indonesia: critical thinking, collaboration, communication, creativity, citizenship/culture, and character education/connectivity. This study explores the eco-literacy of prospective teachers in Universitas Negeri Jakarta, especially during the implementation of the 21st Century Curriculum in Indonesia. The method used in this research is a survey method. The results of the study show that critical thinking was the most challenging part of the 6C’s. Several factors lead to critical thinking becoming the most challenging part of achieving by the prospective teacher. Critical thinking skills include the ability to access, analyze, and synthesize information. A combination of these specific skills will lead to a professional critical thinker. So, this study supports relevant research and provides new empirical data that eco-literacy and critical thinking skills can be learned, trained, and mastered. Within eco-literacy and critical thinking, implementing the 21st-century curriculum in terms of environmental education will contribute to preserving the environment. Therefore, the implementation of eco-literacy must begin early.

Published: July 2021

Abstract
Getting the Adiwiyata predicate is one of the things that schools in Indonesia strive for. But not all schools quickly get this predicate. Preparation and school persistence must be severe to get the Adiwiyata predicate. Many points are assessed in the Adiwiyata program assessment, one of which is implementing curriculum and learning environmental education in schools, whether they are done or not. This study aims to analyze whether the school prepares itself to achieve the goal of being predicated Adiwiyata. This study distributed a questionnaire with 11 questions to principals and teachers of elementary schools in Subang City randomly in 5 districts in Subang. The questions were processed using the cluster analysis, and the level of readiness was analyzed at the point of environmental education-based curriculum implementation. It was found that there were still many schools that had not implemented the environmental education curriculum, both in an integrated manner and in independent subjects. Assistance is needed to carry out supporting learning activities for the Adiwiyata program assessment points. Keywords: environmental education curriculum, adiwiyata.

Abstract
Environmental literacy is a person’s ability to understand and interpret environmental conditions. Based on the understanding and interpretation, the person can decide to maintain, restore, and improve environmental conditions. The goal of environmental literacy is to develop a generation having awareness of and care about the environment, knowledge, skills, attitudes, motivation, and commitment to work individually and collectively to find solutions to environmental problems. This important ability needs to be instilled from an early age because character education in children is long term. This study research uses the literature review method with data collected from books, official reports, organizational websites, and research reports published in national and international online journals. This study aims to examine and describe the steps in instilling early literacy in learning activities in Kindergarten using Kamishibai as learning media. The results of this literature analysis show that instilling environmental literacy using Kamishibai can be integrated in the 2013 Curriculum and can foster students’ awareness of their environment.

Abstract
The National Energy Policy captured the basis for renewable energy development in Indonesia and also specified a national target for the optimal energy mix. For these fundamental reasons, several unprecedented strategies, blueprints, and collaborations are to be explored in the long term. Apparently, one of the key objectives was to exploit natural gas as the primary and eco-friendly energy resource. This profitable gas was projected to significantly contribute a minimum of 22% of total energy toward enhancing economic growth. Approximately, 10 million city gas connections are required by 2025, in order to achieve the set goals. However, a gap exists between the initially planned city gas connections to the distribution network, and the realization during the Covid-19 pandemic in 2020. This global phenomenon poses a challenge to virtually all economic segments, including energy, as the demand plummeted drastically. Based on Indonesia’s National Energy Policy, the first proposed target was to develop 266,070 gas connections. The project was subsequently adjusted to 127,864. Surprisingly, the realization surpassed the new arrangement by over 6% or was about 135,286. However, the figures obviously comprehended 50.84% of the projects were stalled, contrary to the vision of constructing a minimum of 10 million city gas pipe connections in 2025. This study provided a profound description of the impact of the reduction in abovementioned development on the expected outcome, using the multivariable regression method. The results revealed 96.92% of data from the applied variables were able to describe the developed linear model.

Abstract
In 2016-2021, coffee consumption in Indonesia was predicted to increase by 120,000 tons, impacting the increase of coffee waste. Several large coffee industries in Indonesia are located in Taman District, Sidoarjo Regency. The character of the coffee skin waste contains 44.87% organic C; N of 1.69%; P of 0.18%; K 2.49%, and C / N ratio 10-14. This value indicates that the waste can be used as compost because it meets the criteria in SNI 19-7030-2004 concerning Compost from Organic Waste. This narrative review aims to determine the circular economy of bio compost from the coffee industry solid waste to support SDGs point 1 in alleviating poverty in communities around the Sidoarjo coffee industry. The research results showed bio compost I and II is the alternative product in the circular economy (W11). The coffee waste, coffee ground, coffee skin, and coffee returned collects waste in the circular economy (W10). The raw material composition of Bio compost I such as 1.5 kg coffee ground: 1.35 kg of coffee returned:0.15 kg coffee skin+3mL of EM4 and Bio compost II such as 4.6 kg SCG’s:0. 4 kg coffee skin+5 ml EM4. In practice, the circular economy of bio compost I and II can involve Farmer Groups or Youth Organizations around the industry in Taman District, Sidoarjo Regency. Based on data 2020, the total members are 113 people, producing compost of 72,435.5 kg/month with a sales profit of IDR 36,217,750. This practice can support the first point of the SDGs, namely poverty alleviation for communities around the coffee industry. However, studies on the exact circular economy pattern of coffee waste in the Sidoarjo Regency are still needed.

Published: July 2021

Abstract
Child-friendly school is an educational program organized by the government of the Republic of Indonesia to fulfill, guarantee and protect children’s rights. A child-friendly school program, ensuring schools can develop children’s interests, talents, and abilities, prepare children to be responsible, tolerant, respectful, and collaborative. One of the elements of a child-friendly school is from the aspect of school infrastructure it is a). rooms in school buildings are protected from glare and light reflection; b). spaces in school buildings are protected from noise; c). there is sufficient lighting in the classroom. The purpose of this study was to map the readiness of 12 schools that were about to participate in the Adiwiyata school competition, whether appropriate or not. The research was conducted in the Malang Regency Education Office, representing the areas of North Malang Regency, South Malang Regency, East Malang Regency, and West Malang Regency. Data obtained by taking direct measurements to the school using a sound meter. The data obtained were analyzed using descriptive statistics. The conclusion that can be drawn is that the schools proposed to participate in the National Adiwiyata program by the Malang District Education Office do not meet the criteria for child-friendly schools. Suggestions that can be submitted to the Malang Regency Education Office for schools with noise levels above the ideal threshold (55 dB) need to be reconsidered
