With the development of modern electronics and the increase in processing power it is now possible to install many and diverse sensors in a single type of machinery. Temperature, vibration, pressure, voltage, etc. they are variables that are commonly monitored in rotating machinery. These variables together contain all the information related to the condition of the machine. In case of a malfunction, this will be reflected in one or more of the monitored variables. These changes can be so subtle that they can not be noticed directly in the time series. Therefore, it is necessary to transform this information into a new and more useful representation. In the present work an alternative methodology is exposed for the analysis and diagnosis of malfunctions present in components of rotating machinery. This methodology is based on the processing of time series obtained from the sensors installed in the machinery, without considering the model of this. The extraction of nonlinear parameters is presented as an alternative, among which the maximum exponent of Lyapunov stands out, as an indicator of the state of the machine. In conjunction with traditional parameters it makes it possible to detect faults masked due to non-linear behavior of dynamic systems.

Published: March 2021

This study will highlight the elements of Islamic values and Malay traditions in the artworks of 20th and 21st-century Malaysian artists, namely Mastura Abdul Rahman, Haron Mokhtar, and Ruzaika Omar Basaree by discussing the elements of Malay values and Islamic traditions in respect of their artworks. The analyses focused on the artworks from 1980 to 2014, specifically Haron Mokhtar’s “Zahir Mosque”, Ruzaika Omar Basaree’s “Siri Dungun” and Mastura Abdul Rahman’s “House of Harmony” and “ Interior No. 29”. These artists’ works were delivered according to the manifestation of the National Cultural Policy 1971, which highlighted the Islamic and local identity as the main idea and theme of the artworks of local artists. This study has used qualitative methods, which are documentation and observations of each work in the artists’ catalogue as a process of collecting primary data. Meanwhile, secondary data were gathered through referencing academic works like books, journals, and magazines on Islamic values and Malay traditions in visual arts paintings. The analyses found that these works used Islamic art elements, like the “Thuluth” khat in “Zahir Mosque”, as well as the combination of colour and flora motifs on “Siri Dungun”. At the same time, they feature cultural elements, such as “congkak” and “Labu sayong” and traditional Malay ornamental design, which represent the Malay culture and philosophies.

The current re-emergence of global maritime activity has sparked initiative from various nations in re-examining their socio-political and cultural position of the region. Often this self-reflection would involve the digging of the deeper origin and preceding past of a nation from historical references and various cultural heritage materials. From this, realisation of the pattern in maintaining an empire or enterprise from the immediate ancestral society could be turned into a model or benchmark in developing the present and future planning of the nation. In the context of Islamic civilisation development along the Indo-Pacific seaboard the Omani and Malay nations are the two integral entities that had assumed their central role as seafarers, traders, rulers, and travellers in maintaining the dynamics of the region and this happened as early as the Islamic period of the 9th and 10th century CE up till 16th and 19th century when series of European colonial infiltration disrupted greatly the balance of this classical network. The Kitab at-Tarikh Silsilah Negeri Kedah, for instance, presented a vivid story of an Omani captain and his ship in the early 1700s who had met Kedahan people. The cultural heritage of the Arabian Gulf brought mainly by the Omanis could even be found there such as a fabric product known as Baju Maskat and a kind of delicacy known as Halwa Maskat which signal that the cultural hegemony of the Omanis indeed exceeded their immediate political boundary.
THE ADAB OF COMMUNICATION IN CHARACTERS OF HIKAYAT KHOJA MAIMUN
Authors: Hamdan Rahimah
Published: March 2021

Children and Adolescent Literature have yet to find its precise definition in the corpus of Modern Malay Literature. In this regard, the works whose characters consist of adults continue to be enjoyed by children until they eventually complicate the definition of Children’s Literature. Thus, many Western folklore works such as Cinderella, Rapunzel, and others have become the focus of children's reading in Malaysia. Something needs to be done so that reading materials that encounter the East and Islamic values are served to these young people. Therefore, Hikayat Literature through the text of the Hikayat Khoja Maimun needs to be highlighted to replace Western folklore. The objective of this study is to identify characters that communicate in Hikayat Khoja Maimun and analyze the adab of communicating between the characters based on six (6) communication methods in Surah Luqman. The methodology of the study is by text analysis with three main activities to complete the objective of the study which is; to explain the character that communicates in the text of Hikayat Khoja Maimun, to identify the framework for analyzing the communication in Hikayat Khoja Maimun and to analyze the communication between the main characters based on six (6) methods of communication in the Quran through Surah Luqman i.e. through the call, symbolism, repetition, explanation, attention, and selection of idols. The study found that Hikayat Khoja Maimun reserved six (6) adab communicating in Surah Luqman. This denotes that through well-mannered communication, all matters can be delivered easily and successfully. Indeed, Hikayat Khoja Maimun as one of the works in Malay Hikayat Literature serves not only to teach but also to entertain the audience. Finally, it is time that the child reading material in Malaysia being replaced by the magnum opus inherited from generations rather than relying on Western folklore which is far deviating the audience from adab and desired values.

Yabancı Dil Olarak Türkçe Öğretiminde Sözlük Kullanımına Yönelik Öğrenci Görüşleri
Authors: HALAT Sercan , FIRAT Hatice
Published: March 2021

Bir dili konuşabilmek için gerekli olan temel ve en önemli unsur gelişmiş bir söz varlığıdır. Söz varlığının geliştirilmesi sürecinde öğrencilerin, kelime öğrenirken en çok kullandıkları öğrenme araçlarının başında ise sözlükler gelmektedir. Sözlük kullanımı sayesinde öğrenciler hem kelimeleri kendi bağlamları hem de konuşma ve yazma başta olmak üzere dilin temel beceri alanları içerisinde kullanmayı öğrenir. Bu nedenle öğrencilerin, yabancı bir dili öğrenme sürecinde sözlükleri etkili bir biçimde nasıl kullanabileceklerini de öğrenmeleri gerekmektedir. Öğrenciler genellikle sözlükleri kullanırken, basılı ya da çevrim içi fark etmeksizin sözlük kayıtlarında sağlanan zengin bilgilerden, tarama esnasında faydalanamamaktadırlar. Sözlük girdilerindeki bu önemli bilgilere erişilememesine sebep olarak öğrencilerin sözlük kullanma becerilerinin yeterince gelişmemiş olması veya sözlüklerin hedef kitlenin ihtiyaçlarına uygun biçimde hazırlanmamış olması gösterilebilir. Sözlüklerin verilen dönütler doğrultusunda öğrencilerin ilgi ve ihtiyaçlarına uygun biçimde hazırlanması ve sözlük kullanımına yönelik açıklayıcı bilgi ve eğitimlerin verilmesi hâlinde bireyler, yabancı bir dili kullanırken kendilerini daha yetkin hissedeceklerdir. Buradan hareketle çalışmada, yabancı dil olarak Türkçe öğrenenlerin sözlük kullanımına ilişkin görüşleri, sınıf içinde ve dışında sözlük kullanımına yönelik görüş ve tercihleri araştırılmıştır. Alanyazında yabancı dil olarak Türkçe öğrenenlerin sözlük kullanımına ilişkin görüşlerini geniş kapsamlı şekilde ortaya koyan araştırma sayısı yok denecek kadar azdır. Betimsel tarama modelinin kullanıldığı bu araştırmanın çalışma grubunu Jagiellonian Üniversitesi (Polonya) Türkoloji bölümü, Gazi Üniversitesi ve İstanbul Aydın Üniversitesi Türkçe Öğretim, Uygulama ve Araştırma Merkezlerinde (TÖMER) 2018-2019 eğitim-öğretim yılı güz ve bahar yarıyılında öğrenim gören 332 öğrenci oluşturmaktadır. Çalışmada veri toplama aracı olarak uzman görüşleri doğrultusunda, araştırmacılar tarafından geliştirilen ve üç temadan oluşan öğrenci görüşleri anketi kullanılmış, veriler analiz edilerek yorumlanmıştır.
SHORT-TERM DEBT AND FIRMS' EARNINGS MANAGEMENT CHOICES: THE CASE OF VIETNAM
Authors: Vang Quang Dang , Tran Van Hung
Published: March 2021

The primary purpose of this research is to explore the link between short-term debt and firms' earnings management choices. It focuses on understanding how and when short-term debt will improve or reduce the earnings management activity of companies. Our proxy for real earnings management is based on the measure developed by (Roychowdhury, 2006). Using a sample of listed firms in the period of 2009-2018 in Vietnam, the study determines an important positive correlation between short-term debt and real activities manipulation. Our results further show that firms having lower levels of short-term debt tend to use real earnings management activities, but those that have higher levels of short-term debt are prone to use accrual-based earnings management method rather than altering real activities, inducing an inverted U-shaped relationship between short-term debt and real earnings management.
Effect of crop geometry and in situ soil moisture conservation practices on yield attributes and yield of upland rice (Oryza sativa L.)
Authors: Alekhya Gunturi , Jayakrishnakumar V
Published: March 2021

Rice is the most widely grown crop in India. With the decreasing availability of water for irrigation, farmers are now switching towards water efficient production systems such as upland rice. Moisture stress at critical stages is one of the major reasons for low productivity of upland rice. So, the present study was conducted at college of Agriculture, Vellayani, Thiruvananthapuram, Kerala Agricultural University, Kerala, India. The experiment was conducted in RBD with nine treatments including two crop geometries viz., normal planting (20 cm x 10 cm) and paired row planting (10 cm x 10 cm) with 40 cm between paired rows, three rows of cowpea are grown in between two paired rows and in situ soil moisture conservation practices viz., live mulching of cowpea, hydrogel application and coirpith compost application were compared and analysed statistically on yield parameters and yield. Results revealed that, the treatment T9 (Paired row planting with live mulching of cowpea, hydrogel and coir pith compost application) favorably influenced the yield characters and yield of upland rice through proper conservation of moisture and improved availability of nutrients. The treatment T9 recorded the highest grain and straw yields of 3825 and 7700 kg ha-1 respectively with a harvest index (0.48) and was significantly superior to other treatments. It also recorded the highest moisture content in the soil as well as the maximum uptake and availability of nutrients.
Diagnosis and management of green algae in low land paddy fields of Cauvery delta zone, Tamil Nadu
Authors: Jeya Bharathi M , Raju M , Elamathi S
Published: March 2021

Rice is a prime food crop for Asian countries. Wet land rice cultivation contributes maximum grain yield than dry land rice. Cauvery delta is a predominant area for rice cultivation in Tamil Nadu. Green algae growth during Kuruvai (June -August) season is a serious problem in wet land rice. These algae growth create anaerobic condition and prevent rice root respiration. The entire rice root was uprooted and floated on the stagnated water during initial stage. There is no preliminary study for green algae control in rice field. Soil and water samples were collected and analyzed for the nature of occurrence. Laboratory and field experiments were conducted to find out the remedial measures. The results of soil and water sample analysis showed that use of bore well water and dumping of phosphatic fertilizers leads to salt accumulation which favours the green algal growth. The results of the laboratory experiment revealed that the CuSO4 londox power, propiconazole and hexaconazole showed moderate inhibition on 5th day after treatment. The findings from field experiment indicated that use of conoweeder, alternate wetting and drying and CuSo4 drenching @ of 2.5 kg/ha when green algae appearance has just noticed or 5.0 kg/ha when severe growth occurred was effective in managing the green algae. Among all measures, alternate wetting and drying is the best management practices. CuSO4 drenching reduces around 70% of the growth. Even though CuSO4 react negatively with algae growth, soil pH changes and salt concentration play a major role on the CuSO4 action towards green algae. In order to maintain soil health condition, biofertilizer application, crop rotation, green manure trampling to be practised to recover the soil from alkaline pH, removal of accumulated salt and to control the algae growth using CuSO4.

Published: March 2021

A traditional scented rice (cv. Radhunipagal) was tested under varied spacing (20 cm × 20 cm, 20 cm × 15 cm, 15 cm × 15 cm and 20 cm × 10 cm) and seedling age (25, 35 and 45 days) during wet (kharif) season of 2018 at B.C.K.V., Nadia, West Bengal. Seedling age caused significant variation in life duration and summed GDD from 147.9 days and 2436°C day (25-day aged) to 162.0 days and 2753°C day (45-day aged), but with maturity in same meteorological week. Square planting (15 cm × 15 cm or 44 hills m-2) resulted in highest grain yield (2.52 t ha-1), which was 2.85, 11.01 and 4.56% greater over wider (20 cm × 15 cm and 20 cm × 20 cm) and closer spacings (20 cm × 10 cm). Radhunipagal rice raised with 25-days old seedlings recorded the highest grain yield (2.53 t ha-1) and maximum heat use efficiency (0.90 kg ha-1 °C day-1), and that yield was 0.12 and 0.22 t ha-1 greater over the crops planted with 35 and 45-days old seedlings during wet season. Spacing could not influence the cooking and processing quality (gelatinization temperature, kernel elongation ratio and aroma) except protein content of milled rice in the study. Radhunipagal paddy planted with 45-day aged seedlings recorded maximum protein content (6.36%) and alkali spreading value (score 3.27).
HISTORIOSOPHICAL ASPECTS OF THE MONETARY GLOBALIZATION
Authors: SHAROV Oleksandr
Published: March 2021

This article is devoted to the monetary globalization – it is a concept that was at first designed and introduced in academician use by the author in the previous article (Journal of European Economy, vol. 19, No. 3, 2020, pp. 395–408). While the first article considered its geoeconomic aspects – namely the geographical spreading and universalization of the monetary relations, this article focuses on historiosophical aspects – that is, understanding the patterns of development of monetary relations in the context of their globalization. It is emphasized that the emergence of money occurred near simultaneously in different civilizations and the European model was not predestined to become a standard for the world monetary system, but its superiority was ensured in the complex centuries-old globalization process. This concerned not only the formation and spread of monetary relations in the world, but also their universalization, which played a very important role in economic globalization. In this regard, the author points to the role of the state, especially in the last stages of globalization, starting with the formation of the gold standard in the 19th century and ending with the introduction of the Bretton-Woods monetary system and modern processes of its modernization.
UNDERSTANDING EMU ASYMMETRIES AND THEIR ECONOMIC AND POLITICAL IMPLICATIONS
Authors: CASAGRANDE Sara
Published: March 2021

The Covid-19 emergency makes the seriousness of the unsolved political and economic issues that emerged during the European sovereign debt crisis even more evident. Today more than ever it is necessary to answer questions related to the fragility of the EMU architecture: why was the EMU created with an asymmetric structure? What was the role of EMU architecture and European policies during the crisis? Do EMU asymmetries threaten the survival of the Eurozone? The European integration process took place on the basis of a permissive consensus determined by the expectation of successful economic outcomes, without a true democratic legitimacy. Under such conditions, a fiscal and political union was not possible. The EMU proved to be a competitive arena, within which economic and political asymmetries were difficult to manage. An analysis of these asymmetries allows conclusions to be drawn regarding the risks associated with further economic and institutional integration.

Published: March 2021

This article describes a set of algorithms for so-called balancing of numerical matrices, which were developed by the author. Each section consists of several algorithms that are divided into different levels. The order of these levels depended on the chronology of the creation of certain algorithms. Chronology also affected the complexity of these balancing algorithms, so it can be argued that the algorithms are described in order from the simplest level to the most complex. It is important to emphasize that the purpose of the article is to describe the actions on matrices that determine the balancing algorithm of a certain level, and practical application will be the next step.

Published: March 2021

Rapid advancements in the infrastructure of Information and Communication Technology (ICT) have led to radically new but ubiquitous technology; cloud computing. Cloud computing has gracefully emerged offering services that possess on-demand scalability, huge computing power, and a utility-like availability, all at a relatively low cost. It has unsurprisingly become a paradigm shift in ICT, gaining adoptions in all forms of application i.e., personal, academic, business, or government. Not only for its cost-effectiveness but also for its inherent ability to meet business goals and provide strategic ICT resources. More recently there have been advances in cloud computing leading to the evolution of newer commercial cloud services, one of which is the Mobile backend as a Service (MBaaS). The MBaaS is important and required for a robust mobile application back-end data storage and management. Its wide adoption and importance stem from its ability to simplify application development and deployment. Also, MBaaS is robust, with the ability to cope with errors by providing nifty tools and other features. These enable rapid scaffolding of mobile applications. This paper reviews Mobile backend as a Service (MBaaS) and provides required background knowledge on some cloud services and their providers to enable stakeholders to make informed decisions and appropriate choices.
Development and Accuracy Test of a Fused Deposition Modeling (FDM) 3D Printing using H-Bot Mechanism
Authors: Hadisujoto Budi , Wijaya Robby
Published: March 2021

Additive manufacturing process known as the 3D printing process is an advanced manufacturing process including one of the components to support industrial revolution 4.0. The initial development of a 3D printing machine at Sampoerna University is the background of this research. The 3D printing setup of Fused Deposition Modeling (FDM) was built using H-bot moving mechanism by considering the rigidity aspect. The FDM printing method is selected due to its cost and reliability. In this early development, the brackets were custom made using a 3D printer with Polylactic Acid (PLA) material. The result showed that the software worked properly in accordance with the assembled mechanical and electrical parts. The 3D printer could print simple objects such as planes and cubes with small dimensions. However, the printing specimen still lacked accuracy caused by the less rigidity of linear rail brackets, less coplanar belt arrangement, and error in some electronic components.

Published: March 2021

We developed a single ultrasound probe to simultaneously measure blood pressure and changes in the diameter of the radial artery to estimate the wall viscoelasticity during flow-mediated dilatation (FMD). This probe can be used for the early diagnosis of arteriosclerosis. This paper introduces the pulse transit time method to accurately measure changes in blood pressure during FMD. Using the single ultrasound probe and the proposed method, in vivo experiments involving three subjects were conducted, and reasonable results on blood pressure were obtained. Thus, the usefulness of the pulse transit time method was experimentally confirmed.

Published: March 2021

The rate of Soybean (Glycine max) oil (SBO) extraction with a ternary solvent mixture (water, ethanol, and ethyl acetate) optimised with I-optimal Design (IOD) under the Mixture Methodology of the Design Expert (12.0.1.0). The data obtained were analysed statistically. The effect of extraction time (60-180 mins) and temperature (65-70 °C) on SBO was investigated and data obtained were used to evaluate the suitable kinetic and thermodynamic properties of the extraction. The maximum Rate of Oil Yield (32.35 mg/min) was achieved at the solvent mixture of 9.17% water, 6.67% ethanol, and 84.17% ethyl acetate. The Quadratic model best describes the Rate of Oil Yield, with a correlation coefficient (R2) of 0.9922 and an Adjusted R2 of 0.9825. The rate equation for the extraction process is a first-order reaction with ‘n’ value of 1.12756 (≅1.000) while the activation energy (Ea) and Arrhenius constant were 6508.1 kJ/mol and 38.901 s-1, respectively. The study has demonstrated the suitability of I-Optimal Design for the investigation of the Rate of Oil Yield from soybean and the result could be employed in oil extraction process design.

Low-level and medium-level leg injury patients can be operated wheelchair independently in the clinical region. The construction of an electric wheelchair is one of the solutions to operate electric wheelchair by the patients themselves. The motor is an essential part of an electrical wheelchair for driving from one place to another place. The response of the system is very important for the optimization of the system. The existing methods fail in gradual sensitivity during motion and lack of response time to the user. This article is consist of a design for optimizing the existing DC motor transfer function for the smart wheelchair. The perfect angular tuning of the derivative controller provides a better executing time for our proposed model. The smoother responses from the smart wheelchair are obtaining by the dynamic response of closed-loop control. The design of DC motors is to drive smart wheelchair as per the needs. Besides, the construction of a mathematical model for proposing a system involves the DC motor drive to the smart wheelchair arrangement. The proposed model gives independent mobility of smart wheelchair with less response time and better sensitivity. Here, the mathematical model provides the details of immediate response to the user and less execution time of the complex system process. Finally, the authors discussed future improvements to the current DC motor design in the proposed system.

PT. SI is an FMCG (Fast Moving Consumer Goods) of seasoning and foods corporate in Indonesia. PT. SI’s products such as MNG (Mono Natrium Glutamate), Seasoning Flour (SF), a range of condiments, coconut milk, and instant seasoning. PT SI has SF product’s selling data from 2017 until 2020. However, that data yet to be used optimally. That data could be processed further for the organization’s advantage. For example, to knowledge the trend that’s happening, and, for predicting sales value with doing some forecasting and designing DRP. Based on the calculation of the forecasting, we’re obtained the best results using Double Exponential Smoothing by Brown, whereas Mean Absolute Percentage Error’s value is the smallest between the other methods. DRP’s methods make scheduling for the demand of products for determining times and the amounts that needed, and determining plans for arriving products to anticipates sales. With the scheduling, therefore, the distributions can go smoothly and meet the needs of every distribution center. For acknowledging the amounts of trucks that we use, the sums of PORelease is divided with the trucks’ capacities which are 18 tonnages for one delivery, therefore, the delivery costs that we got are multiplied by the transport’s cost for every destination. For distribution costs, company costs are as much as Rp. 20,831,275,897 whereas with DRP method acquired the value for Rp. 17,611,094,522 margins 15,45% from company cost.

PLN Unit Induk Pembangunan Kalimantan Bagian Timur (PLN UIP Kalbagtim) is a company that is responsible for electricity needs in the East Kalimantan region. PLN UIP Kalbagtim covers three types of projects. There are power projects, substation projects, and transmission projects. However, many of these projects experienced delays in their Commercial Operation Date (COD). PLN UIP Kalbagtim only measures the risk level generally and does not measure the root causes of the possible occurrence of this risk. Based on these problems, a study was conducted to identify the projects that experienced delays the most using the Pareto diagram, then analyzed the factors and root causes of the delay using a fish-bone diagram, then using the Analytical Hierarchy Process method, data processing was done to obtain the probability value of each root event. Furthermore, using the Fault Tree Analysis method, the probability value of delay is calculated until the smallest value is found. From the research that has been done, it can be concluded that the transmission project in the form of SUTT is the project that most often experiences delays due to machine, man, material, method, and money factors. The factor that must be set as the priority or focus of the company is the money factor and the root of the incident in it will also be automatically deleted so that the possibility of delays is reduced from 52.71% to 25.28%.
