Abstract
Population increase and urbanization of cities in all countries in recent decades, therefore, ensuring the development of the urban environment has become an important and relevant issue. The article considers the possibility of using a geographic information system (GIS) to ensure the functioning of the city’s transport systems and the selected basic tools of spatial analysis: transport accessibility of the area, air pollution (emissions), noise pollution, energy consumption, route and transport network, traffic and transport network infrastructure. The main components of GIS in the field of transport are analyzed. In addition, it uses methods for collecting, researching, synthesizing, analyzing, evaluating and presenting data on the transport environment of the city. The development of the urban environment is associated with the creation of transport systems that require large costs for movement and economic feasibility.

Method of an automated rapid assessment of the total required revenue in calculating the electric power distribution tariffs
Authors: Shvedova V Y 
Published: November 2020

Abstract
The current electric power distribution tariff-setting processes are too complicated and subjective, and transaction costs in the power distribution industry make up to 50% of all the costs. The method of an automated rapid assessment of the Total Required Revenue of Distribution Network Operators suggested in the article is based on the identified dependencies between the Total Required Revenues of Distribution Network Operators, their cost items and operational indicators taking into account the possibilities of automated data collection from existing and sustainably operating state information systems. On the one hand, such an approach does not require additional expenses on creating and supporting new databases. On the other hand, it allows simplifying the information exchange between Distribution Network Operators and regulating organizations, to reduce the number of papers necessary for calculating electric power distribution tariffs, and to increase the rapidness of tariff-setting processes. As a result implementation of an automated rapid assessment of the Total Required Revenue in distribution tariff-setting processes allows reducing transaction costs and increasing the objectivity of calculations.

Abstract
Investments in real estate are considered by investors as the best way to preserve and increase capital in the long term. Investing in real estate allows the investor to dispose independently of the acquired property at his discretion, including giving and inheriting, and using it for investment purposes - to lease or resell for profit. It is proposed to analyze the algorithm of actions to facilitate the decision-making on the investment purchase of residential real estate and to work out some “unchanged” points of the algorithm that can help in making this decision. Based on this, the stages that are included in this algorithm are analyzed, as well as three types of strategies for investing in residential real estate. A program is considered that allows calculating the profitability of investing in an object for an investor for each type of strategy, using certain factors associated with the property.

Published: November 2020

Abstract
The article presents the results of research of a simulation model of the process of organizing the movement and maintenance of trains at the Railway Station. The model is built as part of a discrete-event approach using the theory of queuing systems and is implemented using the GPSS Studio simulation tool. The simulation model makes it possible to evaluate the efficiency of a Railway Station (workload of personnel, time and delays in servicing trains and performing operations at different stages) to make optimal decisions on organizing the movement of trains and shunting operations taking into account the current situation. Experimental studies of the model were performed on different input data, an analysis of the adequacy of the model was carried out by comparing the experimental results of the workload of the station personnel and the time of operations with the real data of a Railway Station in one of the cities of Russia.

Abstract
Soils are warming as air temperatures rise across the Arctic and Boreal region concurrent with the expansion of tall-statured shrubs and trees in the tundra. Changes in vegetation structure and function are expected to alter soil thermal regimes, thereby modifying climate feedbacks related to permafrost thaw and carbon cycling. However, current understanding of vegetation impacts on soil temperature is limited to local or regional scales and lacks the generality necessary to predict soil warming and permafrost stability on a pan-Arctic scale. Here we synthesize shallow soil and air temperature observations with broad spatial and temporal coverage collected across 106 sites representing nine different vegetation types in the permafrost region. We showed ecosystems with tall-statured shrubs and trees (>40 cm) have warmer shallow soils than those with short-statured tundra vegetation when normalized to a constant air temperature. In tree and tall shrub vegetation types, cooler temperatures in the warm season do not lead to cooler mean annual soil temperature indicating that ground thermal regimes in the cold-season rather than the warm-season are most critical for predicting soil warming in ecosystems underlain by permafrost. Our results suggest that the expansion of tall shrubs and trees into tundra regions can amplify shallow soil warming, and could increase the potential for increased seasonal thaw depth and increase soil carbon cycling rates and lead to increased carbon dioxide loss and further permafrost thaw.

Abstract
As one of the most widespread raptors in Asia, Crested Serpent Eagle (Spilornis cheela) are genetically varied. However, due to the limited studies on genetic aspects, the genetic difference based its geographic distribution are difficult to define. A thorough phylogenetic analysis is needed to create a coherent taxonomic definition for the sake of conservation; starts with phylogenetic analysis based on cytochrome-c oxydase subunit I (COI) gene as the standardized genetic marker to define species. This research was aimed to resolve within species phylogenetic diversity and to explain the relationship between species based on COI gene. Total DNA was isolated from blood samples. The BLAST confirmed PCR amplified COI gene fragments were visualized on 0.8 agarose gel. Sequencing was carried out by FirstBase Laboratory Malaysia. Phylogenetic analysis was done using AMOVA and MEGA7 software in Neighbor Joining method with Kimura-2 parameter. Reconstructed phylogenetic tree confirmed the divergence between three samples and another S. cheela from other regions respective to their geographic distributions. There was 0,014 genetic distance between samples and S. cheela and 0,015 between S. cheela and other species among genus Spilornis. This research also revealed that S. cheela and S. holospilus were not significantly varied.

Abstract
Appropriate propagation technology to promote bamboo sustainability is important in supporting conservation and industrial needs. As part of smart ecotourism package based on the integrated charcoal and bamboo tourism at Lake Toba, this research aimed to develop appropriate propagation for the selected bamboo species. Various bamboo species were collected and propagated by both ex vitro and in vitro propagation. Survival rate of the selected bamboo shoots after 3 months in the ex vitro planting medium was in the range of 25 to 50% of 10 – 25 planted shoots, from the highest to the lowest rate were Bambusa sp., Dendrocalamus asper, Oxythenantera abyssinica, and Balcoa 36. Meanwhile, the efficiency of the shoot formation in the in vitro medium was in the range of 7 to 13%, from the highest to the lowest percentage were D. asper, Gigantochloa cf robusta, O. abyssinica and Bambusa sp. Various types of explant (leaves disc, shoots tips, and nodal segment) from G. robusta and O. abyssinica were induced in six different combinations and concentrations of induction callus medium. Explant from nodal segment of G. robusta and O. abyssinica showed a positive response, i.e., 6% and 20% consecutively, in the Murashige & Skoog (MS) medium containing 4 mg/L of 2,4-D and 0.5 mg/L of IBA. The nodal segment explant of G. robusta was also able to form callus (13%) on the MS medium containing 6 mg/L of kinetin. A similar efficiency percentage was also obtained from O. abyssinica nodal segment explant on the MS medium containing 3 mg/L of 2,4-D and 2 mg/L of kinetin. This research opens a possibility of cultivating bamboo by in vitro propagation and generating new variety of bamboo with desirable characteristics.

Abstract
Lesser-used wood species of jabon (Anthocephalus cadamba) and binuang (Octomeles sumatrana) are potential to be alternative resources to meet wood demand. Wood samples of these two species served as research materials to evaluate wood quality, mainly radial variation of fiber quality and juvenile-mature transition. Fiber quality was analyzed following Rachman and Siagian (1976). Radial variation of fiber and vessel length were used as parameters to estimate juvenile-mature transition using polynomial and segmented regression models. The results showed that jabon and binuang fiber are classified as Quality Class II and I for pulp and paper manufacturing, respectively. Juvenile-mature transition of jabon wood occurred in the segment 6 and 7, while the whole of binuang wood was still juvenile. Boundary between juvenile and mature wood on these wood species was affected by parameter and method applied.

Abstract
Mosquitoes are known for their bites which caused discomfort and its role as vector for various dangerous diseases that has been the bane of humanity since antiquity. One of them is Culex quinquefasciatus which facilitates the spread of arbovirus and nematodes that caused debilitating impact for human life. To eliminate mosquito, the study for evaluating plant-based mosquito larvicidal extract of Cerbera odollam extract against C. quinquefasciatus was conducted. Twenty-five second instar of C. quinquefasciatus were subjected to the crude and fractionated extracts of C. odollam, and the larval mortality was observed at 24, and 48 h of exposure. The results showed that the crude extracts of leaves, rinds, and stem bark exhibited low larvicidal activities. Interestingly, crude extract of the seed kernel exhibited high larvicidal activity. We found that the fractionated extract derived from the seed kernel extract using ethyl acetate and n-hexane exhibited high larvicidal activities, suggesting that C. odollam extract could be promoted as a material for larval control.

AbstractCellulases are the enzymes that hydrolyze β-1,4 glycosidic bonds in cellulose molecules into simpler molecules such as glucose. The cellulase complexes derived from microbes have been considered as a potential source for biochemical, biotechnology, and bioindustry. Thus, they are broadly used in industries for leather tanning, food, medicine, and detergent formulations. The important group of cellulase-producing fungi, such asPenicillium, is reportedly able to produce high levels of cellulase and hemicellulase complexes. This study aimed to determine the characterization and activity of cellulase enzymes produced by fungiPenicilliumand analyze their cellulase activities, both qualitatively and quantitatively. The fungal strain used in this study was obtained from the Indonesian Culture Collection (InaCC) with the accession number of InaCC F15, InaCC F16, and InaCC F17. The parameters used for investigating the enzyme characteristic and activity were incubation time, index of substrate concentration on carboxymethyl cellulose (CMC), temperature, pH, and the effect of the addition of several metal ions as activators and/or inhibitors. The semi-qualitative analysis showed that the clear zone was formed in the surrounding colony ofPenicilliumInaCC F16 with a cellulolytic index was at 3.3. The optimum cellulase activity was obtained on two days incubation period, the temperature of 40°C, pH 5, and substrate concentration at 2%. The addition of metal ions at a concentration of 1mM showed that enzymes were activated by cations CoCl2, CuCl2, MgCl2, and inhibited by NaCl and ZnCl2.

Abstract
The higher consumption of fuel, especially fossil fuels, will lead to depletion of fuel reserves and high air pollution, which causes environmental pollution. Therefore, it is necessary to find alternative fuels that are environmentally friendly and abundant availability in nature, so-called biofuels. One type of biofuel is bioethanol. Raw materials that can be produced into bioethanol are biomass or lignocellulosic material. Elephant grass is one type of lignocellulosic material that has high cellulose content (40.85%). The objective of this study was to determine the optimum pulp concentration by adding Tween 20 to the saccharification process with two types of commercial yeasts (fermipan and mauripan) in the fermentation process. The pulp variations used were 20, 25 and 30% w/v with Tween 20 concentrations 0% and 1%/v. The results showed an increase in pulp concentration, and the addition of Tween 20 by 1% could increase the ethanol content compared to controls (Without Tween 20). The highest ethanol content was produced at 30% pulp concentration (13.09%) with addition 1% of Tween 20 in the saccharification process and fermipan yeast in the fermentation stage, and it could achieve ethanol content of 13.94%(v) when using Mauripan yeast.

Abstract
Tuberculosis is considered one of the leading death causes in the world by a single infectious agent, Mycobacterium tuberculosis (Mtb). The search for a new biologically active compound for the treatment of Tuberculosis is an urgent need due to the rise of multidrug-resistant phenomena. Endophytic fungi were known for a vast reservoir for bioactive secondary metabolites. Endophytic fungi, Diaporthe sp. GNBP-10 associated with gambier plant Uncaria gambier Roxb was able to produce two natural bisantharaquinone, (+)-1,1’-Bislunatin (Bis) and (+)-2,2’-Epicytoskyrin A (Epi), possessing strong antibacterial activities against the various pathogen. In this study, the biological activity screening of (Bis) and (Epi) will be extended by evaluating their activity against Mtb H37Rv. The in-vitro assay was conducted via determination of Minimum Inhibitory Concentration (MIC), nutrient-starvation Mtb, Biofilm Mtb formation, and Mtb-infected macrophage assay. Meanwhile, the in-silico screening was done by docking and Adsorption, Distribution, Metabolism, and Exertion (ADME) studies. Bis and Epi showed promising anti-tubercular activity, as shown by the MIC value of Bis, which is the same as rifampicin (standard drug) at 0.422 μM. Meanwhile, Epi carried out the same MIC value as isoniazid (standard drug) at 0.844 μM. Further investigation on in-vitro assay resulted in Epi and Bis, which were observed for having the ability to combat nutrient-starvation and biofilm of the Mtb model with relatively moderate activity in bacterial reduction with log reduction between 1-2 folds. The cytotoxicity study revealed that Bis possessed high toxicity at all tested concentrations, while the toxicity of Epi decreased as the tested concentrations decreased. Both compounds could reduce the number of Mtb infected into macrophages in 2 folds log reduction. The in-silico result via docking study shows that both compounds have good affinity with pantothenate kinase (PanK) enzyme with a glide score of -8.427 kcal/mol and -7.481 kcal/mol for Epi and Bis, respectively. This study suggests that Epi displayed a potency to be developed further as an anti-mycobacterial compound as it is shown by in-vitro assay, cytotoxicity, and in-silico study. Despite possessing good anti-mycobacterial activity, further studies such as QSAR (Quantitative-Structure Activity Relationship) is needed to improve the physicochemical properties of Epi while maintaining its biological properties.
