Abstract
The corn ussually are harvested at high moisture content ( more 25% w.b.), therefore at those conditions the corn will be very susceptible to damage such as attacked by fungi, bacteria, or physical damage. Drying using mechanical dryer is must conducted on those product to prevent deterioration. In Indonesia there are few resirculated column batch dryer machines with screw conveyor for circulation, however the information of the performance of this dryer is very limited. The objectives of this research is to determine the characteristic of corn drying using those machine. The material is using sheeled corn that have initial moisture 25-30% (w.b.). The corns were dried using the recirculated column batch dryer that have capasity of 2 tons/batch. The drying chamber has diameter of 2,0 m and the height of 3 m. Heat source of this drryer is from liquid petroleum gas that was delivered by high capacity of centrifugal blower. Drying temperature was controlled using automated thermostat that connectd to the gas pipe. Drying experiment was conducted using 45 oC, 55 oC and 65°C. The measurement of moisture content is used for the determination of the drying rate and the drying efficiency. The quality determination parameters used are bulk density, damage, and cleanliness. The results show that the dryer air temperature affected the drying rate, the efficiency of drying, and the quality of the material. The best drying rate with temperature 65°C average 4,95% / hour, high efficiention at dryer temperature 55°C and 65°C equal to 86,27% and 83,51%, and best material quality with dryer temperature 55°C.

Published: November 2019

Abstract
Land use and land cover change are one of the crucial climate change drivers in expanding cities. The land use conversion which alters physical and thermal properties of land surface has also affected the air quality of the urban atmosphere. The paper attempted to investigate how the land use land cover modification can be associated with climate and particle matter variation in Selangor for a decade (2007-2017). PM10 concentration, relative humidity, temperature and wind speed were interpolated using Inverse Distance Weighted (IDW) from six monitoring stations in Selangor and compared to chronological land use changes. The results showed that the land use conversion had induced the variation of particulate matter in the monitoring station located at urban and sub-urban areas. For a decade most land use/land cover had been converted from forest to vegetation areas in northern part and urbanization is expanding intensively to the western part of Selangor in year 2017. Both years have recorded high concentration for particulate matter in Kuala Selangor with concentration of 57.28 µg/m3 and 47.16 µg/m3 respectively. The concentration variation distribution is highly affected during monsoonal, where the stations are located is much significant to be affected by meteorological factor and modification of surrounding land use land cover.

Abstract
Satellite observations of CO2 offer a unique opportunities to improve our understanding of the carbon sources and sinks. Due to the lack of studies of carbon dioxide (CO2) concentration in this region, we first confirmed the reliability of the mid-tropospheric Atmospheric Infrared Sounder (AIRS) CO2 data using atmospheric CO2 concentration data from the only available Global Atmospheric Watch (GAW) ground-based station observation in Malaysia. In this study, the spatial and temporal distribution of mid-troposphere CO2 in Malaysia from January 2009 to December 2012 was analyzed based on AIRS satellite product. The results show that the average CO2 concentrations were high in the eastern part of the study area and lower in the west. From January 2009 to December 2012, the mid-tropospheric CO2 concentrations increased gradually with annual growth rate about 1.293 ppmv/a. There was a significant seasonal CO2 variation with peak concentration was observed during the North-East monsoon (NEM) and the lowest was during South-West monsoon (SWM). The temporal distribution of CO2 concentrations was mainly affected by the amount of sunlight and precipitation received during both monsoons. The study suggested that mid-tropospheric AIRS CO2 data product was able to help in understanding the variations of atmospheric CO2 concentrations comprehensively.

Published: November 2019

Abstract
Fungal contamination in the indoor environment has become the major topic nowadays as it has been related to bad health impacts especially to children as they are more susceptible to diseases. An antifungal agent could act as the remediation to ensure indoor environment become less favorable to fungal growth. However, due to insufficient information on the use of antifungal agents in treating indoor fungal contamination, they were not widely considered for environmental application. The purposes of this study are to collect and identify the type of fungi present in indoor environment of preschool building, to obtain the pure culture of the collected indoor fungi in preschool building and lastly to access the efficacy and compare the efficiency of antifungal agents for indoor fungal remediation. The indoor fungi were collected using Anderson air sampler stage 6 at a classroom of Permata PKPS kindergarten. Wet-mount slide technique was used to identify the fungal colonies collected and they were identified up to their genus level. The fungal colonies were identified as Culvularia sp. and Lichtheimia sp. Pure culture of Curvularia sp. and Lichtheimia sp. were successfully obtained. The efficacy and efficiency of the antifungal agents were assessed using disc diffusion technique through the diameter of zone of inhibition formed. The five antifungal agents tested in this study were tea tree oil, lemongrass oil, vinegar, 70% ethanol and Febreze. Four out of five tested antifungal agents exhibited antifungal properties. They were tea tree oil, lemongrass oil, vinegar and Febreze. The finding of this study shows that lemongrass oil was the most effective antifungal agents as it completely inhibited the growth of both Curvularia sp. and Lichtheimia sp. and also have the ability to inhibit the production of spore of Curvularia sp. and Lichtheimia sp. Hence, lemongrass oil should be considered as remediation for fungal contamination in indoor environment to maintain good indoor air quality

Abstract
This paper presents a conceptual study of ASEAN countries, explore the possibility of developing carbon trading futures and options market from an economic perspective. Owing to market-based complementarity and an invisible hand in the economic market to influence the market and the difference in the development level of ASEAN countries, the joint planning of carbon trading mechanism (carbon trading emission rights mechanism) has become a great trend in the future. The ASEAN countries are currently at a stage of high industrial development; it also brings many pollution problems. How to maintain economic stability and even growth without prejudice to the environment is one aspect of the hard work of scholars studying environmental protection and economists jointly. This paper sets a framework for a carbon trading mechanism to study what impact it will have on the market economy and the environment. It is hoped that this creative idea will be realized and benefited mankind and nature in the future.

Published: November 2019

Abstract
Advances in satellite sensors provide new datasets to assist in the observation of air quality at urban and local scales. Quantitative Aerosol Optical Depth (AOD) and qualitative true colour image data from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on the Terra satellite have been widely used to assess air quality. In this study, both 3 km and 10 km MODIS aerosol products were used to provide an overview of the state of fine particulate matter (PM2.5) and coarse particulate matter (PM10) during haze episodes over Peninsular Malaysia covering the period 21 to 26 June 2013. The result showed a high concentration of PM during the haze period based on ground-level data, with an average level of PM2.5 (mean ± standard deviation) of 99.86 ± 23.99, 190.37 ± 105.59, and 205.191 ± 165.76 (µg/m3) in Tanah Merah station, Cheras station, and Putrajaya station, respectively. Meanwhile, the PM10 in the Tanah Merah, Charas, and Putrajaya stations was 100.56 ± 28.17, 181.31 ± 83.70, and 197.99 ± 74.67, respectively. Overall, the results showed a correlation between monitoring station measurements and satellite data. Satellite remote sensing analysis of atmospheric aerosols remain a great method for estimating haze distribution and can be further used to monitor the atmospheric environment in Malaysia.
The problem of pore fracture growth in a marginal part of a gas-bearing coal seam
Authors: Cherdantsev N V 
Published: November 2019

Abstract
The model of geomechanic state of the coal massif inclosing in-seam working driven along a gas-bearing seam is introduced in the paper. The model is built on the basis of the fundamental concepts of deformable body geomechanics and elastic fracture mechanics. It suggests that the massif is in the state of plane deformation loaded with a stress gravity field. It is assumed that strength characteristics of a coal seam are less than the strength characteristics of the inclosing seam rocks but higher than the strength characteristics along their contact. Coulomb-Mohr and Mohr-Kuznetsov strength criteria are taken as the condition for appearing of inelastic deformation. In this connection, the problem of stress-deformable state of a coal rock massif appears to be an elasticoplastic one. The pore gas pressure changes deep down the seam according to the hyperbolic tangent function. The model assumes that when setting the boundary condition on the seam contact with the side rocks the microfractures containing pore methane are oriented in the direction of a maximum principal stress.

Published: November 2019

Abstract
In the article, the authors analyzed the stable trends in the development of export oil supplies from Russia. The purpose of this article is a short-term forecast of the export of Russian oil with differentiations in the areas of supply. Based on the trend modeling until 2025, a forecast of the total volume of oil exports was made with differentiation in the directions of the supply of liquid hydrocarbons. For each direction of supply, forecast confidence intervals are defined within the limits of which Russian oil exports may be found. The authors showed that export supplies of oil to the energy market of the Asia-Pacific region will increase annually and exports to the European market will decline. The article shows that in the structure of oil supplies from Russia, the main growth is accounted for by foreign countries. In 2018, oil supplies in this direction amounted to 239.6 million tons. At the same time, the share of oil supplies to the European market is annually reduced, reaching only 64% in 2018 (80% in 2011), which is associated with the redirection of oil exports to the Asia-Pacific oil market, primarily to China. In this region, the demand for Russian oil is provided by its higher quality and corresponding chemical composition.
