Banten Province has a city, namely Tangerang, to be precise in the northern part of Banten City. There are many tourist attractions that we can visit in the city of Tangerang, such as natural scenery, historical places, natural scenery, photo spots and culinary tours. With various tourist attractions in the city of Tangerang, it attracts tourists who want to travel to these places. With so many interested tourists visiting the city of Tangerang, the existing hotel is one of the destinations for tourists who are visited for a place to stay and rest. This has had an impact on the increasing number of hotels in the area, which has led to an increasing variety of choices for tourists. To make it easier for tourists to choose a hotel according to their needs, a decision support system is needed in choosing a hotel to use for a place to stay and rest. Tourists can choose hotels according to their desired needs by using a decision support system with various criteria. The decision support system applies the initial criteria weighting by using the AHP method and hotel alternative ranking using the TOPSIS method. The system has been tested and implemented by distributing questionnaires to 30 respondents using the USE Questionnaire and applying the Sala Likert Method to perform the questionnaire calculations, and the final result obtained in the calculation of the questionnaire is 84.51%.

A Modified Hybrid Integral Equation to Electromagnetic Scattering from Composite PEC-Dielectric Objects Containing Closed-Open PEC Junctions
Authors: Liu Jinbo , Chen Hongyang , Zhang Hui , Yuan Jin , Li Zengrui
Published: August 2021

To efficiently analyze the electromagnetic scattering from composite perfect electric conductor (PEC)-dielectric objects with coexisting closed-open PEC junctions, a modified hybrid integral equation (HIE) is established as the surface integral equation (SIE) part of the volume surface integral equation (VSIE), which employs the combined field integral equation (CFIE) and the electric field integral equation (EFIE) on the closed
and open PEC surfaces, respectively. Different from the traditional HIE modeled for the objects whose closed and open PEC surfaces are strictly separate, the modified HIE can be applied to the objects containing closed-open junctions. A matrix equation is obtained by using the Galerkin’s method of moments (MoM), which is augmented with the spherical harmonics expansion-based multilevel fast multipole algorithm (SE-MLFMA), improved by the mixed-potential representation and the triangle/tetrahedron-based grouping scheme. Because in the improved SE-MLFMA, the memory usage for
storing the radiation patterns of basis functions is independent of the SIE type in the VSIE, it is highly appropriate for the fast solution of the VSIE that contains the HIE. Various numerical experiments demonstrate that during the calculation of composite objects containing closed-open PEC junctions, the application of the modified HIE in the VSIE can give reliable results with fast convergence speed.

Published: August 2021

A three-layered transmitting focusing gradient meta-surface (FGMS) has been proposed, which can achieve broadband gain enhancement from 8.2 GHz to 10 GHz. The element of broadband transmitting FGMS has high transmitting efficiencies that over 0.7 and achieve [0, 2π] phase range with a flat and linear trend in the operating band. The FGMS can transform the spherical waves into plane waves. Three patch antennas working at 8.2 GHz, 9.1 GHz, and 10 GHz respectively are placed the focus of broadband FGMS as the spherical-wave source to build a broadband planar lens antenna system. It achieves a simulation gain of 15.44 dBi which is 7.51dB higher than that of the bare patch antenna at 10 GHz with satisfying SLLs and beamwidths. However, it enhanced the gain of the bare
patch antenna in a wide operating band. Finally, the FGMS and the patch antenna are fabricated and measured. The measured results are in good agreement with the simulations.
A Low-Profile Broadband Circularly Polarised Wide-Slot Antenna with an Artificial Magnetic Conductor Reflector
Authors: Fan Fangfang , Fan Xiao , Wang Xiaoyu , Yan Zehong
Published: August 2021

In this letter, a novel broadband circularly polarisation (CP) wide-slot antenna with an artificial magnetic conductor (AMC) as the reflector is presented. The wide-slot antenna is composed of a knife-shaped radiator and an improved ground plane. A broadband CP
characteristic can be achieved by slotting the ground plane to make it an asymmetric ground shape. However, the average gain of the wide-slot antenna is only about 3 dBic because of bidirectional radiation. An AMC reflector is adopted to enhance the gain of the wide-slot antenna without introducing a high profile similar to the PEC reflector. In addition, the four metal plates are vertically placed around the antenna to broaden the
axial ratio (AR) bandwidth of the antenna with the AMC reflector. The measurement results show that the 3dB AR bandwidth of the proposed CP antenna is 32.4% (2.35GHz─3.26GHz), the average gain is 6.5dBic in the AR bandwidth and the value of VSWR in the AR bandwidth is less than 2. The size of the antenna is 0.84λ0× 0.84λ0× 0.13λ0 at the centre frequency of 2.805 GHz. The proposed antenna has a low profile, broad AR bandwidth and high gain, thereby being a good candidate for various wireless communication systems.

Published: August 2021

This article presents a 2×1 CPW ultra wideband rectangular slot antenna array (UWB-RSAA) with a modified circular slot shape to support a high data rate for wireless communications applications. The proposed antenna array dimensions are 0.7λ×0.8λo×0.064λo at the resonant frequency 1.8 GHz. It is fabricated on Rogers RO4003 substrate and fed by using a coplanar waveguide (CPW). A graphene layer is added on one side of the substrate to realize frequency reconfigurability and improve the array gain. The proposed array acquires -10 dB impedance bandwidth of the RSAA that extends from 1.7 GHz to 2.6 GHz, from 3.2 to 3.8 GHz, and from 5.2 GHz to 7 GHz. The proposed array achieved a realized peak gain of 7.5 dBi at 6.5 GHz at 0 Volt bias with an
average gain of 4.5 dBi over the operating band. When the graphene bias is increased to 20 Volt, the antenna bandwidth extends from 1 GHz to 4 GHz and from 5 to 7 GHz with a peak gain of 14 dBi at 3.5 GHz and an average gain of 7.5 dBi. The linearly polarized operation of the proposed array over the operating bands makes it suitable for short-range wireless communications .

Published: August 2021

A public key encryption cryptography system can be utilized to generate ciphertext of a message using a public key. However, this public key encryption cryptography system cannot be utilized if you want to generate ciphertext using several different keys. Solving the problems above can use the Chosen Ciphertext Secure Public Key Threshold Encryption scheme but are the securities from Threshold Encryption really strong in securing messages, therefore the above problems can be analyzed for Data Security Against Chosen Ciphertext Secure Public Key Attacks Using Threshold Encryption Schemes. The work process starts from Setup which functions to generate the server's private key and public key. Then, the process is continued with ShareKeyGen which functions to generate private keys based on the user's identity. After that, the process continues with ShareVerify which serves to verify the key generated from the ShareKeyGen process. The process will be continued again with Combine which serves to generate a private key that will be used in the decryption process. After that, the process will continue with the encryption process of the secret message. The ciphertext obtained will be sent to the recipient. The receiver verifies the ciphertext by running ValidateCT. Finally, the ciphertext is decrypted by running Decrypt. The software created can be used to display the workflow process of the Threshold schema. In addition, it makes it easier to test intercepts of ciphertext messages to other users so that generic securities analysis is carried out in testing the resulting ciphertext. The results of the implementation of  Threshold Encryption algorithm scheme can protect important personal data, because it involves human rights, namely the right to access, the right to delete, the right to correct, the right to be corrected and the right to transfer personal data safely from attacks.

Almost all 1.6 billion people in developing countries have no access to electricity; approximately 85% of the people live in rural areas. Poor people and people in marginal areas, presently depend on natural resources such as wood, charcoal, dung etc. to provide energy for cooking and heating. By 2030, in this category is expected to rise from 2.4 to 2.6 billion people. The result will be greater local competition for traditional energy. So, the rural development can be achieved by promoting locally available renewable energy to meet the basic electricity needs. Decentralised production units are appropriate wherever locally renewable sources of energy are available. Efficient use of traditional and commercial fuels. The main focus of this paper is to present the energy management techniques and different applications of solar energy utilization for the rural people in India to eradicate the poverty in addition to this the role of youth, educationalists, researchers, scientists, politicians and bureaucrats etc. to eradicating poverty in the nation.
Catchment-to-Intake-Point Economic Valuation of Water Resources Using a Hybrid Method
Authors: Mar Iman Abdul Hamid
Published: August 2021

Catchment-to-intake-point (CTIP) economic valuation of water resources is an important aspect of sustainable forest management. With a total of about 94,851 ha of forest catchment area, the state of Johor has among the largest inland water bodies and, thus, water resources in Malaysia. However, the economic valuation of CTIP water resources is rather undeveloped in this country. This paper introduces a hybrid method of CTIP economic valuation of water resources from forest catchment areas based on state-wide Cobb-Douglas translog production function and residual methods, by taking the state of Johor, Malaysia, as a case study. Data on Gross Domestic Product (GDP), labour (L), capital (K), water (W), energy (E), and raw materials (M) were collected for the state of Johor from various secondary sources. Using a pro-rata price in 2014, the total value of CTIP water resources for an assumed lease period of 60 years at 4% per annum is RM 70,272,825.14. This is equivalent to the use-value of water of RM 1,171,213.75 per annum which is an additional source of income to the state government.
Erudition after neonatal gastric transposition for esophageal atresia at 10 years of follow-up
Authors: Sharma Kanika , Sharma Shilpa , Gupta Devendra Kumar
Published: August 2021

Background: Gastric transposition (GT) is a well-established procedure of esophageal re­placement (ER) for children with esophageal atresia. ER in the neonatal period is sparsely reported. We report characteristics of children who have undergone neonatal GT and have completed ten years of follow-up.
Methods: The cross-sectional study was conducted which included all children who under­went neonatal GT at the institute and have completed a follow-up of at least 10-years. An­thropometry, oral contrast study, Hepatobiliary Scintigraphy, Gastroesophageal reflux study, Gastric emptying test, spirometry, and blood investigations were done for all the children.
Results: Four children (three male and one female) were included in the study. The mean age at ER was 5.3 ±2.2 days with a mean birth-weight of 2.43 ±0.13 kg. Two children had prima­ry GT, while the other two had GT following a leak in primary anastomosis. During the mean follow-up of 180.25 ±43.5 months, none of the children required esophageal dilatation or other surgical intervention or procedures. All children were below 3rd centile for weight-for-age while all except one were below 50th centile for height-for-age. There was no stricture on oral contrast study, however, one child had grade III reflux on GER scan. Persistent duode­nogastric reflux on HIDA scan was seen in one child. Three children had restrictive parame­ters on spirometry. Symptomatically, all reported poor weight gain, one had left vocal cord palsy with hoarseness, and one had chest-wall protuberance.    
Conclusions: Neonatal gastric transposition is a feasible alternative to delayed esophageal replacement for neonates with esophageal atresia with limited complications.

Efficient implementation of error correction codes in modular code
Authors: Kucherov N. , Kuchukov V. , Golimblevskaia E. , Kuchukova N. , Vashchenko I. , Kuchukova E.
Published: August 2021

The article develops an efficient implementation of an algorithm for detecting and correcting multivalued residual errors with a fixed number of calculations of the syndrome, regardless of the set of moduli size. Criteria for uniqueness are given that can be met by selecting moduli from a set of primes to satisfy the desired error correction capability. An extended version of the algorithm with an increase in the number of syndromes depending on the number of information moduli is proposed. It is proposed to remove the restriction imposed on the size of redundant moduli. Identifying the location of the error and finding the error vector requires only look-up tables and does not require arithmetic operations. In order to minimize the excess space, an extended algorithm is also proposed in which the number of syndromes and look-up tables increases with the number of information moduli, but the locations of errors can still be identified without requiring iterative computations. By using the approximate method, we have reduced the computational complexity of the algorithm for calculating the syndrome from quadratic to linear-logarithmic, depending on the number of bits in the dynamic range.
Software maintenance improvement in small software companies: Reflections on experiences
Authors: Stojanov Z.
Published: August 2021

Software maintenance has been recognized as the most demanding and costly phase in the software life cycle. Software maintenance tasks, although require a more complex set of skills and knowledge, are far less interesting to software engineers than software development tasks. In addition, insight into the scholarly literature revealed that the knowledge basis on software maintenance is significantly less than the knowledge base on software development. Due to the obvious constraints of small software companies, they do not have time, people, and other resources for assessing and improving their software maintenance practice. This paper presents the author’s reflections on experience in assessing and improving software maintenance practice in an indigenous micro software company.

Published: August 2021

The article presents studies carried out in 2018–2019 and 2019–2020 in the southern foothill zone of the North-West Caucasus in the fields of the selection and primary seed produc- tion department of the Adygh Research Institute of Agriculture. The aim was to study the actual, biological or potential yield of winter soft wheat varieties cultivated in the region, as well as the ratio of the mass of the grain part and the harvested straw - the yield index. The studied varieties were divided into groups according to plant height: semi-dwarfs (up to 90 cm), short-stemmed (up to 105 cm), medium-sized (up to 120 cm). According to the results of the studies carried out, differences in the studied characteristics were revealed. In the group of semi-dwarf varieties, the grain yield varied from 7,25 to 8,05 t/ha, short-stemmed 7,78–8,91 t/ha, medium-sized 7,34–9,60 t/ha. The highest grain yield was shown by the Vekha variety (9,60 t/ha) belonging to the group of medium-sized varieties, from the short-stemmed Maikopchanka varieties (8,91 t/ha) stood out, Kalym semi-dwarf varieties (8,05 t/ha). The biological yield in the experiment varied from 9,37 to 15,29 t/ha. From semi-dwarf varieties, Grom stood out (14,06 t/ha), short-stemmed varieties – Mafe (10,8 t/ha), medium-sized varieties – Vekha (15,29 t/ha). The difference between the actual and biological grain yield of varieties belonging to the short-stem group was the smallest in comparison with the varieties of the semi-dwarf and medium-grown group. On average, over two years of research, the harvesting index was 46,9–53,2%. Semi-dwarf winter wheat varieties had the maximum value of this indicator. In the group of short-stemmed Grom and Graf varieties, the ratio of the mass of the grain part to the harvested straw varied from 46,8% (Velena) to 50,5% (Alekseich). The harvesting index for medium-sized varieties was at the level of 46,9–51,8%. The Vekha variety, which showed the maximum value, stood out from this group.

Expanding the range of products of therapeutic and prophylactic orientation is a priority direction of the state policy in the field of healthy nutrition. Products enriched with functional components improve the general state of the body, have high organoleptic characteristics in combination with increased biological value. The production of synbiotic ice cream is one of the promising trends in the dairy industry. Due to its unique composition and technological peculiarities, the ice cream retains the desired organoleptic and functional properties. Pro- and prebiotic components in it are conserved by freezing, and activated only when they enter the organism. It has been established experimentally, that high concentrations of monosaccharides have an inhibitory effect on the development of probiotic cultures, therefore, the purpose of the research is to simulate the fermentation process of the ice cream enriched with prebiotic components, in order to determine optimal characteristics and establish rational syrup concentrations. Lactic bacteria of Lactobacillus acidophilus species that remain active in a wide temperature range and suppressing pathogenic microflora, as well as berry syrup with a high concentration of vitamins and minerals have been used as components that ensure the functionality of the product. Phased addition of syrup has been recommended for the ex- periment. As a result of the research, a model recipe for synbiotic ice cream has been developed, the quantitative regularities of the influence of various concentrations of fructose syrup on the process of fermentation of compound have been determined, organoleptic characteristics of soft-serve ice cream have been investigated, a power-law model of the dependence of the duration of fermentation on the mass fraction of fructose syrup has been obtained. It has been found that a decrease in the initial concentration makes it possible to shorten the technological cycle and regulate the acidity index.

Post-harvest processing of the leaf mass of various agricultural crops has general patterns. The peculiarity of the structure of the leaves is that the amount of water contained in the leaf blade and in the midrib is approximately the same, but the area of the evaporating surface of the midrib is 10–15 times less than the area of the evaporating surface of the leaf plate. Therefore, the difference in drying modes for these parts of the leaves justifies the need for different physical methods of influencing them. The aim of the research was to substantiate experimentally the general principles of moisture removal from the leaf mass of various agricultural crops using microwave radiation. Processing in the microwave field was carried out for 1,0; 1,5; 2,0; 2,5 minutes. The treated leaf layers were dried naturally. Leaves dried by convection under natural and artificial conditions, only without microwave treatment, served as a control sample. For the post-harvest processing of plantain leaves, a combined drying method is recommended, where in the first phase the leaves are treated with microwave radiation for 2,0–2,5 minutes, depending on the thickness of the leaf layer, and then in the second phase under natural conditions for 8 hours. Microwave – processing followed by convective drying in natural conditions is considered the most compromise method for drying beet tops leaves both in terms of drying time and in terms of the energy intensity of the process. On the basis on the results of the research, the application of the most rational processes of post-harvest processing of leaf mass of agricultural crops was substantiated, which consists in their processing by microwave radiation, followed by convective drying in a natural way.

The rapid development of the latest innovative technologies that improve human life have tragic consequences. The irreversible and cruel reverse side of the progress is the emergence of various diseases and pathologies. Cardiovascular diseases occupy a leading position in the morbidity and mortality of people of different ages in the world. Functional food products can be used to prevent diseases of the heart, the blood vessels and the thyroid gland. One of the ways to increase immunity of the population can be the expansion of specialized food production that are balanced in the content of macro- and microelements, take into account the peculiarities of metabolic processes, pathological conditions that occur at different ages in people. Pork, enriched with microelements in its lifetime, is a promising raw material for improving the technology of organic pork production. The developed technology for obtaining organic meat raw materials has passed various tests in the farms of the Krasnodar Territory, which are the main suppliers of pork for the manufacture of specialized functional products. For the manufacture of a specialized meat product, meat without lard has been used. The article presents studies of nutritional and biological value, nutritional adequacy of pork and by-products enriched while alive. Specialized pasteurized meat products enriched with microelements (iodine and selenium) have been developed, and the qualitative composition of a specialized meat product has been disclosed, which can be used to prevent cardiovascular diseases and diseases of the thyroid gland. Experiments have been carried out on laboratory animals (white rats) to confirm the biological effectiveness of a specialized meat product.

Objective: To conduct a community-based cross-sectional survey to determine the prevalence of human immunodeficiency virus (HIV) among pregnant women in taluka Ratodero, Larkana, and two adjacent talukas: Sajawal, district Kambar Shahdadkot and Garhi Yasin, district Shikarpur.

Methods: The study was conducted among pregnant women in the three talukas of rural Sindh: Ratodero, Garhi Yasin, and Sajawal, from October 16, 2020 - December 23, 2020. A total of 1,157 pregnant women were interviewed at their homes and tested using the AlereTM HIV Combo rapid finger prick test. The study captured women's sociodemographic, economic, and health characteristics, including age, education, employment, number of children, home or hospital delivery, antenatal care use, antenatal trimester, history of blood transfusion, and HIV test result. Descriptive statistics were calculated: percentages for categorical variables and mean ± standard deviation (SD) for continuous variables.

Results: It was found that 0.35% (4/1,157) of women were HIV-positive, of which 3 were in Ratodero, Larkana, and 1 was in Garhi Yasin, Shikarpur. The average age of women was 28.7 ± 4.0 years. Most of the women (n=1067; 92.2%) of women did not attend a school, and 99.0% (n=1145) had never had a formal job. The average gestational age was 7.6 (±2.2) months. More than three-quarters of the women participating in the study (n=894; 77.3%) were not registered with a formal healthcare facility for antenatal care.

Authors: Juldin Muhammad , Alfa Akbar
Published: August 2021

AbstractConcrete is a composite material (mixture) consisting of cement, coarse aggregates, fine aggregates and water. The concrete formation mixture is designed in such a way as to produce fresh concrete that is easy to work with and meets the plan's compressive strength after hardening.The cement used is PCC type cement, although the composition of cement in concrete is only about 10%, but the role of cement is very important in concrete. Aggregates are mineral granules originating from nature or artificial which have a function as a mixture of fillers in concrete. The aggregate of the concrete mixture filler is divided into fine aggregates used from Javanese Inhu and coarse aggregates from Tanjung Balai Karimun. The fine aggregate is usually in the form of sand that passes through a filter with a diameter of 4.75 mm or 5 mm, while coarse aggregates do not pass through the filter. The water used is well water from Kateman District, Keritang District and Tembilahan District, Indragiri Hilir Regency, Riau Province.The compressive strength of concrete is the amount of load per unit area which causes the concrete specimen to break and there is no more carrying capacity. The average compressive strength of 28 days of cube specimens with well water in Kateman District = 491 kg / cm2, Keritang District = 469 kg / cm2 and Tembilahan District City = 475 kg / cm2.
