Published: June 2020

Peatland areas generally have raw water with different characteristics compared to ordinary raw water. Peat water is acidic (pH 2 – 4), blackish brown in colour (250 – 600 TCU) and contains various other pollutants so it cannot be processed with conventional technology. The aim of this paper is to publish the capability of IPAG60 to treat raw peat water. This technology uses a simple and applicable process in producing processed water that is suitable for clean water and drinking water according to quality standards. The formulation of the purifying material applied was able to remove organic matter and other pollutants with high efficiency (more than 90%). The results of research conducted on several types of peat water coming from different locations such as Kalimantan and Sumatra show that IPAG60 is capable to treat peat water into clean water meeting the standards. The use of IPAG60 is not only limited to treating peat water, but also for various conditions of inland surface water.

Published: June 2020

Developing area is a multidimensional process and often has minimum attention in water management aspect. Sentul City is an example of an area in Bogor Regency that is growing rapidly but has problems in water management. The limitation of raw water is caused by the lack of groundwater and frequent disruption in the water distribution system. This causes the raw water supply depends on the Local Water Company of Bogor Regency. In fact, Sentul City has the potential to conduct independent raw water from its high rainfall. Therefore, rainwater harvesting is needed through stormwater management, one of its application is by the rain garden. The objective of this paper is to present the research result of the rain garden model recommendation that is suitable to be applied in Sentul City. The used methods are mapping the existing site conditions, analysis of the rain garden suitability, calculate the rain garden dimensions, and modeling the rain garden. This study conducted in Lake Indah, Lake Teratai, Siliwangi Street, M.H Thamrin Street, and Plaza Niaga 1. The rain garden analysis and dimensions are affected by the soil, topography, catchment area, and runoff volume of the site. The required rain garden surface area is 171.50 m2 at Lake Indah, 312.48 m2 at Lake Teratai, 6,449.88 m2 at Siliwangi Street, 6,573.01 m2 at M.H Thamrin Street, and 896,51 m2 at Plaza Niaga 1, while the required rain garden depths are 15-30 cm and 45-60 cm.

Sustainable household water-saving and demand management options for Kabul City
Authors: Shokory J A N , Rabanizada E
Published: June 2020

Increasing water demand has led to water scarcity in many urban areas in the arid and semi-arid regions. Indeed, population growth and the expansion of urban and industrialized areas have put great pressure on water resources. Currently, Kabul city is facing groundwater shortage, which is the main source of potable water. Due to rapid urbanization and population growth, and climate impacts, the groundwater level is lowered (∼ 1m/year), which has led to many wells drying out in recent years since 1998. Therefore, this study focuses on alternative options to sustain water resources and achieve water sustainability through implementing water-saving practices, including tapping new water resources (rainwater harvesting), and some of the options (faucet aerators, low-flow showerheads, and dual flush toilets), others as gray-water reuse. To analyze the potential of rainwater in Kabul city, long-term precipitation data from 1960-1980 and 2006-2013 from several stations around the city are used. The rooftops of the dwellings assumed to account for 30% of the total land area, according to the State of Afghanistan City 2015 report. Moreover, existing household water efficiency is compared to the most efficient available technologies. The result indicated 346 mm annual average precipitation, and 38.0 million m3/Year the potential precipitation volume that could be harvest from dwellings rooftops in Kabul city. Moreover, the rainwater harvesting could produce an average of 29 L/capita/day (LCD) of water for domestic usage, with a maximum of 75 LCD in February, a minimum of 5 LCD in September, and an annual 9593 L/capita/year (LCY). If we manage the maximum months, then it could produce the full domestic usage (38.1 LCD) until July. Furthermore, in terms of demand management, we have performed a case study on Macrorayon’s (1st, 2nd, 3rd, 4th) apartments that if low flow fixtures were utilized, how much water could be saved? The Macrorayon Department estimates the service population of its system at 100,000 people, the volume of consumption calculated to be 12,500 m3/day (125 LCD). Results show that after application of low flow fixtures, per capita consumption can be reduced to 57 LCD, 2.08 MCM/Year would be saved; and an additional population of 119,298 people would be covered by water supply. The result of this study is essential for policymakers to adopt current and future water challenges in Kabul city.

Published: June 2020

This paper is about the improvement of the E-Request Transcript system used by POLISAS to be a systematic and effective system. The improvement is implemented to solve the current problem, whereby, students need to access the E-Request Transcript system according to the graduation session in individual file. This situation makes it difficult for the administrators to access more than one E-request transcript system if the application is from different sessions. It is because of the data-access issues to generate reports. To achieve the system improvement, an integrated database using the query optimization technique is implemented. Next, the query statement is analysed to produce an optimum performance. Research results show that the technique is able to improve the query time processing, thus resolving the issues discussed. A user acceptance test for this system consists of a black box test and a beta test has been deployed. A black box test was conducted to test the main menu functions in the E-Request transcript and is found to be able to succeed. Furthermore, the beta test is carried out using a survey form distributed to all students who have graduated. Survey questionnaire showed that 57% of respondents were satisfied using this system and 14% were very satisfied with this system. All respondents have provided a good scaling rate for all items assessed. For overall system assessment, the mean score obtained is 3.78 which is interpreted as a good rate based on the scale of interpretation used. In conclusion, this system has met the needs of consumers as well as simplifying their business based on surveys conducted.

Dengue is a mosquito-borne viral disease that is surging and becomes worldwide serious issues. Currently, due to lack of specific treatment or vaccine against dengue, many forms of vector control remains a key strategy for dengue fever prevention. In response to the issue, this paper introduces an AedesTech Mosquitoes Home System (AMHS) that is equipped with a special trade secret formulation or also called as Insecticide Growth Regulator (IGR) and combines with Internet of Things (IoT) technology for vector control. An IGR is a pheromone-like liquid formulation that is a chemical that serves to stimulate and have sexually attract the male and female that will attract and lure adult female mosquitoes to lay eggs in them, and the adult mosquitoes will soon die after lying eggs. Those eggs that already laid with the chemical will not hatch or die at an expected of 99% rate, or go beyond the pulp level. Our sustainable approach offers for two (2) novel features. First, to monitor the collection of Aedes eggs in our MHS, we develop a mobile apps called AedesTech Apps (ATA) for Aedes eggs auto-counting and data collection are stored in cloud based server. Second, to monitor the level of liquid formulation (IGR) in AMHS, we utilize an Arduino water based sensor to real time track the IGR level status and we called as Intelligent Mosquito Home System (iMHS). Our iMHS will automatically alert the user when refill is needed. Both technologies are related to IR 4.0 that could be a new approach for preventing and monitoring of dengue outbreaks. This sustainability approach are environmental friendly and cost saving that provide the solution to the world’s global issue of dengue. The results by our ATA tool indicate a satisfactory figure with only 0.01 to 0.04 percent of error rate compared to existing ICount and EggCounter tools. Meanwhile in our iMHS with water based sensor, testing results reveal that the battery lifetime solely depends upon the setting of interval time of sending data to cloud server. Results show for a half an hour interval, battery could last for a half of a month whereas for an hour interval time set, it could last for a month.

Published: June 2020

This paper demonstrates an improved image steganography that hides grayscale secret image into grayscale cover image using RDWT and QR decomposition. The proposed scheme made use of the human visual system in the information hiding process. Both cover and secret image are being divided into non-overlapping image blocks with identical block size. Entropy values generated from every image block will be sorted from the lowest value to the highest value. The embedding process starts by embedding the secret image block with lowest entropy value into the cover image block with lowest entropy value. The process goes on until all image blocks have been embedded. Embedding secret image into cover image according to the entropy values causes differences that HVS can less likely to detect because of the small changes on image texture. The proposed scheme gives higher PSNR values and better image quality.

Ensuring the processability of construction disposal during design
Authors: Pavlov A P , Mitrohin N N
Published: June 2020

The level of organization of recycling and recycling processes in Russia has been assessed. The questions of the level of consumption of resources in production are presented, which gives an idea of the potential possibilities of unification not only of design solutions, but also of the nomenclature of used materials. It has been established that technological efficiency of recycling provides not only reduction of total costs for the recycling process itself, but also allows to more fully use the potential of working capacity of parts laid down during their production. The possibilities of ensuring the processability of the product design during its disposal at the design stage are considered. One of the most effective methods of ensuring the processability of the structure during recycling is to use the system of repair kits during design, which allows simultaneously increasing the processability during production, operation and repair. The proposed approach makes it possible to significantly reduce not only the time spent in repair of ground-based transport and technological means (GTTM), but also to significantly realize the possibility of providing technological effectiveness in recycling GTTM themselves and their units and parts. The use of repair kits formed at the design stage allows increasing efficiency not only during maintenance and during repair of GTTM, but also during their utilization and recycling.

Published: June 2020

The subject of the study is to optimize the compositions containing frost-resisting complex organic and inorganic additives (FRA) that provide the required level towards freezing temperature when constructing cement-mineral layers (CML) of road dressing (pavement). As a prerequisite to carry out these studies is the necessity to preserve the liquid phase in CML during asphalt laying at low (subzero) air temperatures, as well as ensuring a given level stated to the performance criteria and durability of road dressing layers. In our studies, we applied the comprehensive approach to the experiment, concluding in a choice of FRA components and in the use of experiment planning. The influence of functional additives and their quantitative composition on the freezing temperature (Tz
) during the experiment optimization in line with the D-optimal second-order plan has been considered. A mathematical model of the process has been obtained. We have found that the most significant mixture is the content of sodium formate (SF), compared to calcium chloride (CaCl2) and a superplasticizer based on the polycondensation product of naphthaleisulfonic acid and formaldehyde (C-3), the amount of which varies in the series 3>1>0.3. The obtained results on optimization allow to choose FRA compositions that provide the ability to perform construction works in conditions of subzero temperatures up to −15.6 °C.
Refined assessment of strength of concrete pavement probabilistic method
Authors: Stepushin A P , Chistyakov I V , Goryachev M G , Sadovnikova Y S , Kyaing A K
Published: June 2020

The object of research is the method of calculating the strength of cement concrete airfield pavement. According to the current regulatory documents, the calculation of the strength of the coating is carried out according to the first limit state, taking into account the internal forces arising in the slab from the impact of the wheel load and temperature. The repeated impact of loads from the wheels of the main supports of various types of air is replaced by the influence of the main support of the heaviest aircraft, causing the greatest bending moment in the design section of the plate. However, the calculations do not take into account the stochastic nature of such factors as the take-off weight of aircraft, the plate thickness, the bed ratio of the elastic foundation, the probability of the combined effect of operating loads from the main bearing wheels and temperature in the calculated section of the plate, as well as the probability distribution of loads from the aircraft spectrum across the width of the airfield elements. The article proposes a method for taking into account the probabilistic-statistical variability of operating loads, physical and mechanical properties of materials and the geometric characteristics of the plate, recommended when developing a new regulatory framework for the design of rigid airfield pavements. The method of statistical linearization of random functions of several random arguments was chosen as the research method. Using the mathematical apparatus of the theory of random functions, the statistical coefficient of the working conditions of the plate is analytically determined, and a numerical analysis of the obtained analytical solution is carried out. It has been established that with the same unfavorable combination of variability of basic arguments, the calculated absolute value of the statistical coefficient of the working conditions of the slab is more influenced by the coefficient of variation of the slab thickness than the coefficient of variation of the strength of cement concrete in bending. The condition for calculating the required thickness of the hard airfield slab of monolithic cement concrete is determined.

The unified transport system of Vietnam includes road; rail; river; sea and air transport. Road freight transport has a particularly important role and provides for the delivery of goods, especially in large cities. Transport problems and the problem of improving the quality of freight transport in Viet Nam are classified as difficult and still not resolved. The paper analyzes the role of road freight transport in the economy. Here we propose a refined approach to determining the rationing of fuel consumption of trucks and its features in Vietnam conditions. By assessing the influence of various factors on fuel consumption, it is possible to increase the accuracy of standardization and reduce fuel consumption.

Published: June 2020

This article raises questions about the processes of bibliometric ICT-tools used by the scientific community in the automobile and road industry. This refers to scientific developments in the field of digitalization, in the operation of motor vehicles services, maintenance and design of highways, safety and traffic management. Modern ICT-methods can be implemented in the form of work with abstract and bibliographic databases, such as Web of Science, Scopus, Russian Science Citation Index, which show scientometric indicators of the publication activity of scientists, individual groups of researchers, organizations and journals. The following areas have been studied in the areas of scientometric databases: automotive industry, road complex and traffic flow management. Our study is devoted to the search for the above areas in the bibliography and the development of methods for providing a separate study to build its scientific activities and publication activity on an international scale. The study revealed that the above areas also include many other areas that, one way or another, affect the interests of other scientific fields. Due to the fact that the scope of scientometric databases is different, in order to study the scientific activities of scientists or journals, it is necessary to consider all indicators comprehensively in all databases. The rating trajectory of Doctor of Engineering Sciences, Professor M. Yashina, was also constructed, according to Web of Science, Scopus and Russian Science Citation Index.

Published: June 2020

The tire tread (inflated) may have a convex (toroidal) shape. At present, there is practically no data on the influence of this structural parameter of the tire on its power and kinematic characteristics when rolling with a slip. The solution to this problem, given in this paper, is based on the consideration of contact phenomena in the friction pair “elastic wheel – rigid support surface”. As a result, relationships that make it possible to determine the lateral force, the turning moment acting in the contact area, the friction loss in the contact area for wheels with different toroidalities as a function of the slip angle and the longitudinal tangential force realized in the contact area are obtained; conclusions about the influence of the convexity on the lateral force, the stabilizing moment and the power of friction losses in the contact area are drawn.

The urgency of the problem of removing burrs from parts of coaxial radio components is due to the fact that, according to technical requirements, burrs are not allowed on these parts, and on materials beryllium bronze, brass, alloy 29 NK used for their production, it is not possible to exclude the appearance of burrs during processing by cutting. The analysis of the influence of technological heredity of the number and size of burrs obtained on the CNC automatic turning operation to the choice of the method of deburring. The parameters of the burrs that affect the choice of the method of deburring, and the degree of their influence on the choice of a particular method are determined. On the CITIZEN bar lathes, an experimental selection of the cutting tool and processing modes was carried out in order to minimize the number and size of burrs on parts made of beryllium bronze, brass, alloy 29 NK. The installation of selected processing modes and tools will ensure the production of parts of coaxial radio components at the turning stage with a minimum number and size of burrs, which will reduce the laboriousness and time of deburring.

The article is dedicated to the description and discussion of theoretical models that may be used for calculating the level of service indicators for road network. Authors developed the approach for calculating the level of service indicators for urban road network sections with signalized intersections. The core of the proposed models of assessing the level of service is based on the method, developed by American experts for main roads and adapted by the authors for the city roads. The approach to assessing the level of service is based on the advanced analytical model of the fundamental diagram, describing various phases of traffic flow. Herein authors introduce the concept of a laminar traffic flow in the sections of the road network, which is implemented for the level of service calculating.

One of the urgent tasks is to determine the composition of the bus fleet to serve each route. At the same time, it is necessary to be able to vary the type and number of buses that have different technical characteristics, in this regard, in the framework of the study, the issues of optimizing bus movement modes on city routes were considered. Basically, on the city route network, buses stop at all stopping points. However, quite often there is a situation when there is a sufficiently large unevenness of passenger traffic at various stopping points. In this regard, design schemes for analyzing the effectiveness of combined and shortened routes are proposed. Key relationships include empirical estimates of passenger flows. The parameters of the models are the volume of the bus fleet, the irregular production of buses, the probability of a denied boarding at individual stopping points.
