Published: October 2021

Perlunya manajemen pengawasan dan kontrol kualitas terhadap peredaran susu segar di masyarakat, adalah merupakan upaya mencegah adanya pemalsuan susu dengan bahan lain dan cemaran yang dapat mengkontaminasi susu sehingga menjadi tidak layak untuk dikonsumsi. Penelitian ini dilakukan pada bulan September sampai Oktober 2019, bertujuan untuk mengetahui gambaran kualitas susu segar ditingkat Koperasi Unit Desa (KUD), Tempat Penampungan Susu (TPS) dan Peternak di Kecamatan Dau Kabupaten Malang. Sampel susu segar diperoleh secara langsung dari lokasi Peternakan, TPS dan KUD sebanyak 30 sampel. Data yang diperoleh dianalisa secara deskriptif analitik. Hasil analisa kualitas susu segar dengan menggunakan uji organoleptik adalah meliputi warna, rasa dan aroma tidak menunjukkan adanya perubahan atau normal. Sementara hasil analisa uji alkohol, derajat keasaman, sedimentasi, lemak, redukatse (MBRT) masih dalam kisaran normal sesuai Standar Nasional Indonesia (SNI). Pada Uji total bakteri (TPC) untuk masing-masing sampel susu segar dari KUD, TPS dan Peternak rata-rata jumlah bakteri adalah 5,2 ± 2,5 x 10⁴cfu/ml yang masih dibawah standar SNI yaitu kurang dari 1,0 x 10⁶ cfu/ml. Sehingga dapat disimpulkan bahwa susu segar yang beredar di Kecamatan Dau Kabupaten Malang dalam keadaan aman, baik dan layak untuk dikonsumsi. Higiene peternak/pemerah beserta ternaknya, sanitasi kandang dan peralatan pemerahan susu serta penyimpanan hasil susu yang baik merupakan faktor penting terpeliharanya kualitas susu segar yang dapat menjamin keamanan masyarakat dalam mengkonsumsi susu segar tersebut.

Published: October 2021

River flood events have recently been increased due to many reasons such as climate change and excessive land usage. Thus, one of the greatest challenges is to control the flooding in urban areas. River flooding has become a phenomenon worldwide in general and in Iraq specifically. This is associated with the rapid increase of urbanization as well as mismanagement of land utilization; especially those located near the river banks, in addition to lack of consideration in terms of the design and implementation of drainage networks. In Iraq and especially in Al-Anbar governorate, studies in the field of flood simulation control have been rare. This study aims to suggest a fast and accurate methodology for local authorities, by providing a proposed solution and prediction of flooding area in the case study of the Fallujah barrage. Global Mapper software has been used to produce simulation photos on flooding area. Earth Explorer USGS website has been used to download water body data; and Global Digital Surface website has been used to extract and download the surface elevation data. The result of the simulation photos has predicted valuable information about the flooding area and proposed a general vision on the areas that are under threat of flooding. Four main areas were exposed to flooding, area 1, area 2, area 3, and area 4; A total flooding area of 11.89 km2. The total maximum operational level for the barrage was designed to be 44.79 m above sea level. Also, the recommended maximum operation level for the barrage was 43 m ASL.

Published: October 2021

For the sake of enhancing the mechanical properties and durability of asphalt concrete, many studies suggest adding different admixtures, such as waste materials in the form of filler. These admixtures have a significant influence on the performance of asphalt concrete by plying a roll in filling the voids between particles and sometimes as a cementitious material. This study aims to improve the strength of asphalt concrete by adding crushed animal bone to the mix after carbonization at a temperature of 800 Co. Seven different percentages (10, 20, 30, 40, 50, 60, and 100%) of animal bone ash as a replacement for the filler percentage were added to the optimum asphalt concrete mix. A number of tests were conducted on asphalt concrete specimens to measure Marshall stability (MS), Marshall flow value (MF), voids filled with asphalt percentages (VFA), air void percentages (VA), voids in mineral aggregate percentages (VMA), and maximum theoretical specific gravity (GMM). From the results, the maximum stability of 14.85 KN was reached when using animal bone ash of 20% as a partial replacement for the conventionally used filler (limestone). In general, there are some improvements in the physical properties of asphalt concrete with animal bone ash, which can be related to the increase in the bond between the particles of aggregates and the bitumen material.

Published: October 2021

The aim of this work is to study the mechanical behavior of the sediments extracted from the Koudiet Meddaouar, Timgad dam (Algeria), for a possible valorization in the field for building works in order to minimize this phenomenon which is currently a concern for the operators and the persons in charge of the mobilization of the water resources. This siltation therefore severely limits its storage capacity and consequently it’s operating life. The extraction of the sediments accumulated in the dam's reservoir is therefore imperative, on the pain of seeing it perish in the medium term. These sediments are, however, of great geotechnical and mechanical value. The results of the tests conducted in the laboratory have enabled us to identify the different sediments from a physical and geotechnical point of view In front of the difficulties noted in the control of the silting up of the dams in Algeria, a very important quantity of silt being deposited annually in the dams. In order to achieve our objective, different mixtures of silt with or without lime treatment, cement glass fibers and powdered fibers were studied for the possible manufacture of Compressed Earth Bricks (CEB). The results obtained show that some of the mixtures present very interesting results in the different tests (compression and bending), verifying the conditions of the standards in force and thus allowing their use in the field of the manufacture of building materials.

GA-Optimized Multivariate CNN-LSTM Model for Predicting Multi-channel Mobility in the COVID-19 Pandemic
Authors: Widiputra Harya 
Published: October 2021

The primary factor that contributes to the transmission of COVID-19 infection is human mobility. Positive instances added on a daily basis have a substantial positive association with the pace of human mobility, and the reverse is true. Thus, having the ability to predict human mobility trend during a pandemic is critical for policymakers to help in decreasing the rate of transmission in the future. In this regard, one approach that is commonly used for time-series data prediction is to build an ensemble with the aim of getting the best performance. However, building an ensemble often causes the performance of the model to decrease, due to the increasing number of parameters that are not being optimized properly. Consequently, the purpose of this study is to develop and evaluate a deep learning ensemble model, which is optimized using a genetic algorithm (GA) that incorporates a convolutional neural network (CNN) and a long short-term memory (LSTM). A CNN is used to conduct feature extraction from mobility time-series data, while an LSTM is used to do mobility prediction. The parameters of both layers are adjusted using GA. As a result of the experiments conducted with data from the Google Community Mobility Reports in Indonesia that ranges from the beginning of February 2020 to the end of December 2020, the GA-Optimized Multivariate CNN-LSTM ensemble outperforms stand-alone CNN and LSTM models, as well as the non-optimized CNN-LSTM model, in terms of predicting human movement in the future. This may be useful in assisting policymakers in anticipating future human mobility trends. Doi: 10.28991/esj-2021-01300 Full Text: PDF

Published: October 2021

One source of learning in universities is a digital library. In the era of industry 4.0, most universities have implemented digital libraries in supporting the learning process. However, the reality shows that digital library management is still ineffective. Therefore, the implementation of digital libraries needs to be evaluated for determining the digital library effectiveness used as learning resources in supporting the learning process in universities. Many evaluation tools are used to evaluate the effectiveness of digital libraries but have not provided accurate recommendation results to support decision-making. This research presents an innovation in the form of an evaluation tool that can be used to evaluate the digital library effectiveness in universities. That evaluation tool is called the Alkin-WP-based digital library evaluation software. This software is a desktop platform that contains aspects of measuring the digital library effectiveness by referring to the components of the Alkin evaluation model and the WP (Weighted Product) method. This research aimed to show the effectiveness level of the utilization of Alkin-WP-based digital library evaluation software. This research method was R & D (Research & Development) which refers to the ten development stages of the Borg and Gall model. In this research, development was focused only on a few stages, included: usage trials, final product revision, dissemination, and implementation. The subjects involved in assessing the implementation/utilization of the Alkin-WP-based digital library evaluation software were 35 people, in the usage trials were six people, in product revision were three people, and at the stage of dissemination were 15 people. The tools used to collect data were questionnaires and interview guidelines. The data analysis technique used was descriptive quantitative. The effectiveness level of utilizing the Alkin-WP-based digital library evaluation software was 88.34%. It showed that the evaluation software had effective. The impact of this research results on the scientific field of educational evaluation is being able to show the existence of a new evaluation tool based on educational evaluation and artificial intelligence. That evaluation tool can easier for library heads to make policies for revamping digital library services based on accurate recommendations. Doi: 10.28991/esj-2021-01308 Full Text: PDF

Published: October 2021

Bingöl merkezinin tarihi çevre ve şehircilik bakımından gelişimi odaklı çalışmalar, bu güne kadar dolaylı ve az sayıdaki akademik çalışmalar ile sınırlı kalmıştır. Ancak geçmişten günümüze kadar doğudan batıya ve kuzeyden güneye birçok ulaşım yolarının merkezinde yer alan bu coğrafyanın merkezini teşkil eden Bingöl şehrinin ve yakın fizikî çevresinin değişim ve gelişim seyri ile bu değişime etki eden unsurlar merak konusu olmuştur. Bu incelemede, Bingöl şehri veya bölgeye merkezlik eden yerleşim birimlerinin değişim tarihleri, sebepleri, yerleşim alanları ve konuşlanmış oldukları alanların şehirleşme ve yerleşim bakımından durumları gözlemlenmiştir. Bu açıdan bakılınca, şehrin veya bölgenin tarih öncesi dönemlerden bugüne taşıdığı adları, coğrafî konumu, jeomorfolojik yapısı, demografik, idarî, askerî, siyasî, sosyal, coğrafî, kültürel vb. şartlarının devirler boyunca şehir ve çevresinin değişimi ve gelişimine etkileri önem kazanmıştır. Bu çerçevede yapılan inceleme, ilk çağlardan ortaçağlara kadar Bingöl ovası ve çevresinde günün şartlarına uygun önemli ve stratejik yerleşim ve yapılaşma şekillerine yer verildiğini göstermiştir. Ancak takip eden dönemlerde Bingöl ve merkezî bölgesinin çevre ve gelişim bakımından muhtelif nedenlerle ıssızlaşmaya başladığını ortaya koymuştur. Bölgenin idarî merkezini oluşturan yerleşim birimi, bu ıssızlaşmaya binaen köy niteliğine sahip bir özellik kazanmıştır. Yerleşim birimi ve yakın alanı, geniş bir şehircilik imkânı ve anlayışına sahip olamamıştır. Bu şartları ile yaygın ve kendine özgü geniş bir fizikî ve kültürel etki oluşturamamıştır. Bu durum büyük ölçüde Osmanlı Devri’nin ve Cumhuriyet Dönemi’nin ilk yarısına kadar devam etmiştir. Ancak yakın zamanlarda şehirle ilgili bir çevre ve şehircilik anlayışından bahsedilebilir olmuştur.
Cumhuriyet Dönemi’nde şehrin kuruluş yeri, gelişim dönemleri ile nakledilen yeni yeri jeomorfoloji ve afetlere maruz kalma açısından araştırılmıştır. Şehrin bugün bulunduğu alanın jeomorfolojik özellikleri ile gelişme doğrultusunun jeomorfoloji ile uyumlu olup olmadığı ortaya konulmuştur. Burada, şehir yerleşimini etkileyen doğal afetler, resmi özel yapılaşma, vb. durumlar da gözden geçirilmiştir. Bu amaç doğrultusunda çalışma alanına ait topoğrafya haritalarından Sayısal Yükseklik Modeli (SYM) oluşturulmuş (10*10 m), SYM’den yükselti basamakları ve eğim haritaları elde edilmiştir. SYM’den eğim ve yükselti özellikleri elde edilerek şehir, kuruluş yerinin elverişliliği bağlamında değerlendirilmiştir. Çalışmada Bingöl şehir yerleşmesinin geçmişten günümüze maruz kaldığı ve kalabileceği doğal afetler ortaya konmuş ve çözüm önerileri sunulmuştur. Bingöl şehir yerleşmesinin gelişme dönemleri ve doğrultusu için farklı dönemlere ait Landsat TM 5 ve Landsat 8 OLI-TIRS uydu görüntüleri kullanılmıştır. Çalışmada 1985, 1990, 2000 ve 2010 yıllarına ait Landsat TM 5, 2019 yılı Landsat 8 uydu görüntüleri kullanılmıştır. Uydu görüntülerinin farklı bantları ARCGIS 10.1 programı ile birleştirilmiş (Composite Bands), şehrin gelişme dönemi ve doğrultusu belirlenmiştir.

Greenbug resistance in barley landraces from Uzbekistan
Authors: Radchenko E. E. , Dyatlova K. D. , Akimova D. E. , Zveinek I. A. 
Published: October 2021

Background. The greenbug (Sсhizaphis graminum Rondani) can significantly reduce the yield of barley and other cereals in the southern regions of Russia. Cultivation of resistant varieties can significantly limit the pathogen’s harmfulness. At the same time, specific interaction with the genotypes of the host plant, characteristic of S. graminum, requires a continuous search for new resistance donors to broaden the genetic diversity of barley cultivars. Materials and methods. The resistance of 178 accessions of barley landraces from Uzbekistan to the Krasnodar greenbug population was tested in laboratory experiments. Juvenile plants were infested with aphids of different ages, and when the susceptible control died (cv. ‘Belogorsky’), resistance was assessed on a 0 to 10 (plant death) rating scale. Plants with a damage rate of 1–4 points (up to 30% of the leaf surface being damaged) belonged to the resistant class; damage rate of 5–8 points indicated moderate resistance of plants, and that of 9–10 meant susceptibility. In addition, we assessed the aphid damage of the winter barley cultivar ‘Post’, protected by the previously identified resistance gene Rsg1.Results and conclusions. We identified 52 barley accessions as heterogeneous for the studied trait. In six accessions, plants with high (points 3 to 4) and moderate (5 to 8) resistance were identified; 6 accessions were differentiated into 3 phenotypic classes: resistant, moderately resistant, and susceptible; and in 40 accessions the manifestation of the resistance component varied within 5 to 7 points (from 31 to 60% of the leaf surface being damaged). The distinctly expressed resistance of 12 accessions is controlled by alleles of resistance genes that differ from Rsg1. After selection for resistance, the identified accessions can be used in breeding.
Analysis of the genotype × environment interactions and assessment of the adaptability potential in barley under the conditions of the Northern Trans-Urals
Authors: Tetyannikov N. V. , Bome N. A. 
Published: October 2021

Background.Crop yield is a compound and complex character in breeding programs. A stable high yield is determined by the genotype, environmental impacts, and their interaction. A comprehensive assessment of cultivars based on their adaptability, plasticity and stability makes it possible to select among the studied assortment the most promising, potentially high-yielding and environmentally flexible plant forms adaptable to a wide range of environmental conditions.Materials and methods. Evaluation of 146 accessions representing two-row (subsp.distichonL.) and six-row (subsp.vulgare) barleys (Hordeum vulgareL.) was performed in 2015–2017 to measure the adaptability, stability, plasticity and homeostasis of barley yield. Experimental data were statistically processed using the methods of the two-way ANOVA and correlation analysis.Results and conclusion. It was established that barley yield formation was almost equally determined by the genotype (34.3%), environmental conditions (31.9%), and genotype × environment interactions (33,7%), showing that the tested barleys were relatively well adaptable to climate changes in the Northern Trans-Urals. Barley yield was more closely associated with grain weight per plant (r = 0.72) and the number of productive stems per area unit (r = 0.63), and to a lesser extent with seed germination rate in the field (r = 0.39) and 1000 grain weight (r = 0.37). Strong correlations were observed for the yield with the adaptability coefficient (r = 0.94), environmental plasticity index (r = 1.00), and compensatory capacity (r = 0.96). Cvs. ‘Abyssinian 14’ (k-23504, var.pallidum) and ‘Kharkovsky 70’ (k-23683, var.nutans) exhibited a set of adaptive and productive properties.

Mathematical modeling of a self-propelled scraper at the beginning of soil set
Authors: Kovalevskyi Sergii 
Published: October 2021

The process of filling of scoop of dragshovel consists of a few operations which periodically repeat oneself in the working loop. Each of these stages is accompanied the different moving of dragshovel and his separate knots, conditioned actions of external forces, at cutting and load of soil in a scoop, that needs separate consideration of the tense state of dragshovel equipment in a few calculation positions.
The analysis of the modes of ladening of metallokonstrukcii of dragshovel during implementation of basic operations of digging allows to define the rational modes of operations of machine.
For the decision of the put tasks the calculation chart of self-propelled dragshovel was developed in the process of zaglubleniya of knife in soil, on the basis of which taking into account the grounded limitations and scope terms, a twomass mathematical model, having degrees of freedom in horizontal and vertical directions, is created. With the purpose of simplification of mathematical model the angular vibrations of tractor and dragshovel were not taken into account, in connection with their small influence on the operating loadings at zaglublenii of scoop.
Realization of mathematical model allowed to get the charts of dynamic change of horizontal and vertical force, operating in the hinges of hauling frame. Swaying character of loadings rotined that maximal values were arrived at almost for the identical interval of time in the first semiperiod, and horizontal and vertical efforts increase with the increase of intensity of resistance digging.
The results of researches rotined that forces operating in the front hinge of hauling frame grow with the increase of intensity of resistance digging, arriving at the maximal values of 195 and 78 kN. Horizontal efforts to a great extent exceed vertical and increased with growth of intensity of resistance digging. The rate of increase of maximums of horizontal force can be considered even, because at megascopic intensities from 150 to 250 kN/m, most values grow approximately on 32 %, that enables to draw conclusion about expedience of work with the less rates of movement of dragshovel, taking into account loading of metallokonstrukcii.
The rate of growth of maximums of vertical force can be considered even, approximately on 7 %, with the increase of rate of climb of knife of dragshovel, that far fewer as compared to growth of efforts, operating in horizontal direction. Therefore diminishing of speed of zaglubleniya will not result in the substantial diminishing of loading on the hauling frame of dragshovel.
