Published: March 2022

Loyalitas pelanggan, keputusan membeli kembali serta kepuasan merupakan salah satu konsep yang paling sering diteliti oleh akademisi. Kesetiaan, pembelian kembali dan kepuasan pelanggan memiliki dampak yang kuat terhadap kinerja perusahaan dengan memberikan keunggulan kompetitif, semakin banyak pelanggan setia, maka tingkat kepuasan pelanggan meningkat. Meskipun sebenarnya penelitian (hubungan antara loyalitas pelanggan, pembelian kembali dan kepuasan) ini dilakukan secara ektensif, namun semuanya tampak kompleks dan multidimensional, sehingga sulit dipahami dengan baik.Pada penentuan tipe pelanggan berdasarkan review komentar online, fitur yang dihasilkan dari dokumen review tersebut sangat banyak. Sehingga akurasi klasifikasi rendah.Adapun beberapa teknik seleksi fitur dengan metode filter yaitu dokumen frequency dan ChiSquare. Metode Chi Square lebih sering digunakan untuk pengklasifikasian dengan dokumen yang banyak bila dibandingkan Information Gain. Semakin banyak jumlah dokumen yang digunakan dalam klasifikasi dapat meningkatkan nilai F-Measure klasifikasi teks dengan metode Chi Square.Berdasarkan analisa di atas maka penulis akan menggunakan metode Naive Bayes dengan Correlation-Based Feature Subset Selection (CFS). Dengan metode tersebut, diharapkan akan menghasilkan klasifikasi pelanggan dengan nilai akurasi yang baik untuk digunakan dalam review produk.Dengan menggunakan Cfs mengalami peningkatan nilai recall dari 88,50%, menjadi 94,78%. Dengan demikian membuktikan bahwa algoritma ini mampu menjawab NB cukup optimal digunakan untuk mengklasifikasikan pelanggan pada dataset komentar toko online
Women in Public Sphere after The Implementation of Islamic Sharia in Aceh
Authors: Roviana Sri , Udasmoro Wening , Nurlaelawati Euis
Published: March 2022

This article discusses several activities intended for Acehnese women after the implementation of Islamic sharia. Activities aimed at women in public spaces have an impact on the marginalization and narrowing of women's public spaces. This article also explicitly provides an overview and analysis of what actually happened to Acehnese women so that it appears that there is a problem of the domination of male power over women based on religious, cultural, and political arguments. The purpose of this article is for the public to understand that the Aceh government has made policies aimed at women in the public sphere with the support of Wilayatul Hisbah, which has an impact on the marginalization of women. It is found that after the implementation of Islamic law in 2001 until now, in Aceh, there have been domestication of women with various regulations (qonuns) as well as text interpretations which are used as legitimacy by the power of conservative ideology on progressive understanding. This article makes Aceh a focus area. This article is based on the literature as a secondary source as well as interviews with experts.
The Practice of Tabut in Bengkulu: A Shared Tradition of Sunni And Shia
Authors: Valentine Femalia , Warsah Idi , Morganna Ruly , Daheri Mirzon
Published: March 2022

This study explains how the existence of Tabut is interpreted so that it becomes a tradition in the Sunni’s community. It is important to understand how this ritual is maintained in the midst of the Sunni-Shia’s conflicts which continue to occur. The present study was qualitatively conducted using a field research method. The members including the leaders of Keluarga Kerukunan Tabut (KKT) and those of Tabut Pembangunan as the community handled by the government were engaged as the participants of this study. The data collection techniques deployed interviews, observations, documentation, and literature reviews. The present study revealed that the existence of Tabut’s tradition which is claimed to be a tradition originated from Shia’s teachings is able to maintain its presence in Bengkulu. This existence survives in the middle of Bengkulu’s society that is predominantly Sunni. This tradition is capable of being a peaceful path between Sunni and Shia in Bengkulu because each of them succeeds in creating social interactions through the Tabut’s tradition as human relations and the symbol they interpret. As an implication, this study highlighted that a religious or cultural activity can be a medium of social bondage in the midst of cultural diversity. This study contributes to being a reference for those who have interests in anthropological, social, and religious fields.
Expression of Love for Ahl Al-Bayt in Acehnese Society
Authors: Hakim Lukman , Rijal Syamsul
Published: March 2022

Theologically, the Acehnese ordain themselves as loyal followers of Sunni Islam, but there are Shi’a elements in their culture. To date, there are some traditions of expressing love for the Ahl al-Bayt (Prophet Muhammad’s family) which is one of the main characteristics of the Shi'a. This research is based on the hypothesis that several cultural practices in Aceh contain Shi’a elements. This study seeks to reveal the cultural practices of the Sunni followers in Aceh in expressing their love for the Ahl al-Bayt. This study uses a qualitative approach with a descriptive analysis method from a combination of library and field data. This study found that, historically, the acculturation process of Shi'a culture into the Sunni followers in Aceh has coincided with the process of the arrival of Islam in the Indonesian Archipelago. This is possible given the position of Aceh in the history of Islamization in the Indonesian Archipelago. This acculturation has left traces of culture inspired by Shi’a such as the tradition of Ashura porridge, Boh Husayn cake. All these traditions have been preserved because these Shi'a values contain expressions of love for the Ahl al-Bayt who also have a place in the hearts of the Sunni adherents in Aceh.
Ethnic Stereotyping and Intra-Religious Conflict: The Experience of Muslims in Sambas of the Indonesian West Borneo
Authors: Kurniawan Syamsul , Sirait Sangkot , Muslim Azis
Published: March 2022

This paper aims to explore the impact of ethnic differences and ethnic stereotyping on the atmosphere of peace, written based on the conflict event between Muslims of different ethnicities (ethnic Malay of Sambas and ethnic Madurese) in Sambas in 1999. This paper, based on my research from 2018, is qualitative research with data obtained from observation, interviews, and documentation. Regarding the method, this research used a qualitative method that leads to a case study model as an investigative method. Meanwhile, for data analysis, the interactive data analysis method using the theory of self-categorization was employed. Based on the findings of the study, ethnic differences and stereotypes had a significant impact on the escalation of conflict between Muslims in Sambas in 1999. These ethnic differences and stereotypes essentially emerged as a consequence of the way a person or group of people of a particular ethnicity categorizes a person or group of people of another ethnicity.
Selection by differential mortality rates
Authors: Cecconello M. S. , de Assis R. A. , de Assis L. M. E. , Venturino E.
Published: March 2022

In this work, a partial differential equation model for evolutionary dynamics is presented that describes changes in densities of phenotypes in a population. We consider that the traits of individuals of a population are distributed at an interval of real numbers where a mortality rate is assigned for each value of this interval. We present some conditions for stability of stationary solutions and apply the model in theoretical scenarios of natural selection. Particularly we approach cases of stabilising, disruptive and directional selection, including the scenario of the survival of the flattest. Some computational simulations are performed to illustrate the results obtained.
Iterative methods for extended general variational inequalities
Authors: Benhadid Ayache
Published: March 2022

In this paper, we suggest and analyze a new approximation schemes (3) to solve the extended general variational inequalities (2), which were introduced by Muhammad Aslam Noor (see[7, 9]). Using the projection operator technique, we establish the equivalence between the extended general variational inequalities and the fixed-point problem. This equivalent formulation is used to discuss the existence of a solution of the extended general variational inequalities. Several special cases are also discussed.

Approximating intuitionistic fuzzy fractals by densifiability techniques
Authors: García Gonzalo
Published: March 2022

We present a sequence of sets converging, under suitable conditions and respect to the Hausdorff intuitionistic fuzzy metric, to the attractor set of certain intuitionistic fuzzy iterated function systems. For this goal, we will introduce a fuzzy version of the so called α-dense curves which have been used by the author to approximate, with arbitrarily small and controlled error, the attractor set of certain (metric) iterated function systems. In this way, we relate the above mentioned concepts of the intuitionistic fuzzy metric spaces with the α-density theory.

We suggest viable solutions, aimed at improving the robustness of experimental research in sociology, taking advantage from consolidated rigorous praxis developed in other disciplines.
Dogma Antropocenului în reevaluare: înapoi la scepticismul educat
Authors: SCHNEIDER Henrique
Published: March 2022

The Anthropocene is a proposed geological epoch dating from the commencement of significant human impact on Earth’s geology and ecosystems, including, but not limited to, anthropogenic climate change. While this is not an academically established definition, as of yet, it is said to have begun in the 1950s. This article posits that the concept is erroneous in at least two ways. First, it relies on a normative and activist appropriation of science. Second, it disregards the system-property of the ecosystem, which consists in the continuous interaction between the system and its parts, or agents. Above all, however, the Anthropocene as a notion is a case study exemplifying how activist agendas appropriate science and academia while ignoring an important feature of scientific research: scholarly scepticism and scrutiny.

The use of solid teak wood has always been the choice of casing manufacturers for communication technology tools. This type of teak wood has the requirements for durable class and maximum strength class. Other types of wood are considered less qualified, one type of wood is Mindi wood, whereas Mindi wood actually looks beautiful. In the digital era, various forms of manufacturing casings made of plastic are offered, of course, plastic materials have a negative impact on the environment and seem cheap. Wood is a solution for providing materials in the manufacture of environmentally friendly casings of exclusive value. In order to achieve an exclusive concept in the era of fashion trends, the right method is needed in its cultivation, so this design uses a method that includes several stages, including, a) Observation and analysis stage, b) The imagination stage consists of exploration and experimentation of techniques and materials. , c) The stage of developing the imagination which is focused on the maturation of the concept as a result of the evaluation of the problem, d) The stage of implementing the design decisions that are ready to be worked on. The above method is then called the method of creating Practice-Ied Research. The design achievements along with the current trend and fashion era emphasize the character and contemporary lifestyle, but will also display a sentimental character that seems nostalgic for the past. Tend to accentuate the ancient and exclusive impression that offers the uniqueness of the wood grain, this is often referred to as a retro style product.Penggunaan kayu untuk produk industri saat ini telah nyata mendukung peningkatan Produk Domestik Bruto (PDB) dari sektor non minyak. Hal demikian ditandai dengan maraknya beragam produk estetis ataupun fungsional oleh pelaku bisnis berbahan kayu. Sebagian besar para pelaku mengacu pada trend dan fashion yang mencerminkan karakter dan gaya hidup kekinian, tetapi jarang sekali menampilkan karakter sentimentil yang seolah-olah bernostalgia ke masa lalu. Penggunaan kayu jati solid kelas satu selalu menjadi pilihan sehingga mengabaikan kayu-kayu yang lain, padahal kayu Mindi justru tampak sifat lokalitasnya, sehingga cenderung menonjolkan kesan kuno dan eklusif yang menawarkan keunikan serat kayu.  Guna menuju pencapaian konsep kuno diperlukan sejumlah experiment dan metode yang tepat dalam penggarapannya, yakni: a) Tahap observasi dan analisis, b) Tahap imajinasi, c) Tahap pengembangan imajinasi, d) Tahap implementasi. Metode tersebut kemudian disebut dengan metode penciptaan Practice-Ied Research.

Merebaknya virus Covid-19 memang memberi dampak yang sangat signifikan bagi kehidupan manusia tidak kecuali aspek pendidikan anak usia dini. Pendidikan anak usia dini yang semula dilakukan dengan tatap muka berubah menjadi jarak jauh, pendidikan yang semula dilakukan secara bersama-sama kini dilakukan secara mandiri di rumah masing-masing. Intinya banyak terjadi perubahan di dunia pendidikan anak usia dini bahkan mungkin tidak pernah terbayangkan sebelumnya termasuk aspek bermain anak yang menimbulkan dampak psikis dan sosial motorik bagi tumbuh kembang anak. Kebijakan pembelajaran jarak jauh yang ditetapkan oleh pemerintah pun tidak mampu mengatasi permasalah pendidikan anak usia dini yang merupakan generasi penerus bangsa, meskipun akses internet telah tersedia, pembelajaran jarak jauh secara daring masih menyimpan tantangan dan belum mampu menjawab kebutuhan bermain anak usia dini. Tantangan serupa pun dihadapi oleh orang tua yang harus beradaptasi dengan lingkungan pembelajaran anak di rumah. Untuk memenuhi kebutuhan pendidikan anak usia dini serta menunjang proses pembelajaran anak diperlukan ruang belajar yang mendukung dan membuat anak bersemangat dalam bermain di masa pandemi. Peran lingkungan pembelajaran dengan mengatur setting ruang yang cocok untuk aktifitas bermain anak perlu untuk di kaji lebih dalam. Penelitian ini akan fokus pada pola adaptasi yang dilakukan oleh playgroup maupun orang tua dalam mensiasati ruang bermain anak usia dini.

Objectives: To assess the factors that influence the frequency of dental hygiene in adults with cerebral palsy, determine the caregivers’ difficulties in performing dental hygiene, and relate to their sociodemographic characteristics. Methods: In this observational cross-sectional study, a questionnaire was applied to 257 caregivers from 27 institutions who participated voluntarily. Information on dental hygiene practices, sociodemographic characteristics, and caregivers’ difficulties in performing dental hygiene was obtained. Data were analyzed with SPSS® version 25 with a significance level of 5%. Nonparametric tests were used to define predictors of frequency and difficulties of brushing by caregivers and determine prevalence ratios and confidence intervals. Spearman’s correlation was used to study the relationship between variables. Results: Brushing was performed twice a day by 23.7% of caregivers and never by 21.8%. The caregivers with less training in dental hygiene performed brushing more frequently (OR=0.247; p=0.001). Brushing frequency was lower in the presence of bleeding, lack of cooperation by adults with cerebral palsy, and when caregivers had higher education and age. The following problems were relevant for the relationship between difficulty in performing brushing and frequency: “pulling the head away” (p<0.001) and “not opening the mouth” (p=0.005). Conclusions: The predictors influencing dental hygiene frequency were younger age and a higher education level of caregivers. The lack of collaboration, as well as “pulling the head away,” by people with cerebral palsy increases the difficulty of performing oral hygiene.

Authors: Gunawan Juniati , Susilo Hermawan
Published: March 2022

This study aims to seek theㅤinfluenceㅤof corporateㅤsocialㅤresponsibilityㅤdisclosures (CSRD) on share prices with the company's reputation as intervening variable. The samples are derived from all of the consumer goods industries, which areㅤlistedㅤonㅤIndonesiaㅤStockㅤExchange during 2014-2018. Content analysis method is used to measure the company’s corporate social responsibility disclosures based on company’s annual reports and/or sustainability reports. Unlike previous studies, this research applies the Sustainability Accounting Standard Board (SASB) as the disclosures list to award the scores. Panel regression method and Eviews 9 were applied as analytical tools. Findings shows that CSRD does not influence the corporate reputation, but in contrast, CSRD influence significantly and positively to the share prices, and so does the corporate reputation. However, CSRD does not influence the share prices when it is mediated by the corporate reputation as intervening variable. When CSRD and Reputation were examined together, controlled by ROA, these variables positive significantly influence the corporate share price.

Authors: Youns Majed D. , Abdulla Abdulla I. , Attya Salih M.
Published: March 2022

This paper presents LQR and GA controllers which applied to control the speed of a DCmotor and to maintain the rotation of the motor shaft with particular step response. Inthe state space, the control strategy is the states feedback and the most used techniquesare the LQR. Liner quadratic regulator (LQR) provides an optimal control law for alinear system. It’s a control strategy based on minimizing a quadratic performanceindex. In despite of the good results obtained from these method, the control design isnot a straight forward task due to the trial and error method involved in the definition ofweight matrices. In such cases, may be hard tuning the controller parameters in order toobtain the optimal behavior of the system. In this work, it proposes a states feedbacktechnique in which there are no trial and error processes involved and the control designis carried out to fulfill specifications, for minimize overshoot and minimize settling andrising times. The proposed technique is based on the use a genetic algorithms. Theobtained results show that is possible to design controllers which fulfill designspecifications.

Thermosyphon is considered a heat transfer device in which its operating principle depends on theevaporation and condensation of a working fluid which use the gravity forces to ensure the fluidcirculation. In the present paper, thermosyphon has been constructed to simulating the actualapplications to study the characteristics of heat transfer and its influence on the variation of crosssection shape. This paper, includes the procedure of a series experiments for three iron tubes invertical position with different cross section shape (square, rectangular and circular) having thesame hydraulic diameter and total length. Many factors have been investigate to distinguish theireffect on the heat transfer coefficient and temperature distribution on the surface. These variablesare: various cross section shape, heat input and coolant flow rate of the condenser, with themethanol as working fluid of fixed rate at operating pressure which is near to the atmosphericpressure. It has been demonstrated that from the total comparison of all shapes in the sameconditions, the performance of the square thermosyphon is higher than that of circular andrectangular thermosyphon, respectively. Also, it has been found that the highest value of the heattransfer coefficient at the square thermosyphon (1812W/m2oC) when it is compared with thepractical results of the other two types geometric shapes.

Mass Transfer And Hydrodynamics In A Split-Column Airlift Photobioreactor
Authors: Zmat Amer D.
Published: March 2022

Overall gas-liquid mass transfer coefficients of oxygen gas (KLa) at different axiallocations of the riser and downcomer of a split-column Airlift Photobioreactor wereinvestigated using FOXY Fiber Optic oxygen sensor supported by NeoFox viewer software.The effect of bubble dynamics on mass transfer was considered. A 4-point optical probe wasused to measure local interfacial area (a) and other bubble dynamics parameters for both theriser and the downcomer of a split-column airlift photobioreactor. Having both overall masstransfer (KLa) and interfacial area (a) measured at different locations, local oxygen masstransfer coefficient (KL) can be determined for each location along the riser and thedowncomer of the airlift bioreactor. Effects of different operating conditions (0.3 – 2.8 cm/ssuperficial gas velocity) on both mass transfer and bubble dynamics of the riser and thedowncomer have been investigated for air-water system. It was found that both local masstransfer and gas-liquid interfacial area are considerably varying from the bottom to the top ofthe riser and the downcomer of the bioreactor. It was found that local mass transfer coefficientvaries by 100% from the bottom to the top of the riser at low superficial gas velocity (1 cm/s)and by 30% at relatively high velocities (2-2.8 cm/s). The Trend of the variation of the KLa inthe downcomer section of the column is very different from that of the riser, as it was noticedthat insignificant mass transfer takes place at the lower part of the downcomer. The results ofmass transfer and bubble dynamics in the riser and the downcomer of the studied conditionswill be presented and discussed.
Parametric Simulation on Enhancement of the Regenerative Gas Turbine Performance by Effect of Inlet Air Cooling System and Steam Injection
Authors: Alkumait Aadel A.
Published: March 2022

Iraq being one of the developing countries of the world considers energy efficiency and the impact of its generation on the environment an imperative process in improvement of its power generation policies. Iraq bearing high temperatures all year long results in reduction of air density, therefore, Inlet air Cooling and Steam Injection Gas Turbines are a striking addition to the regenerative gas turbines. Regenerating Gas turbines tend to have a high back work ratio and a high exhaust temperature, thus, it leads to a low efficiency in power generation in hotter climate. Moreover, STIG and IAC through fog cooling have known to be the best retrofitting methods available in the industry which improve the efficiency of generation from 30.5 to 43% and increase the power output from 22MW to 33.5MW as the outcomes of computer simulations reveal. Additionally, this happens without bringing about much extensive change to original features of the power generation cycle. Furthermore, STIG and spray coolers have also resulted in power boosting and exceeding generation efficiency of gas turbine power plant.

Authors: Haido James H
Published: March 2022

The consideration of novel response spectrum analysis to check the reinforced concrete RC buildings resistance towards the seismic risks in Iraq has not been investigated so far. Due to the increasing of frequent earthquakes with moderate intensity in north of Iraq, caution should be taken into account in building design especially with considering the design codes. Where, there are no specific Iraqi standards of earthquake for building design. Thus, the proposing of new response spectrum relationship matching the properties of Kurdistan region (north of Iraq) soil is considered essential with considering of novel stiffness or inertia reduction factors for concrete sections. Present endeavor is devoted to develop new design spectra dynamic analysis of RC multistory building located in Duhok city-Iraq. Influence of proposed concrete section reduction factors on the analysis outcomes has been investigated also. Great role has been observed for introducing of stiffness reduction factors in present seismic analysis represent in magnifying of lateral deformation of building of more than 50%. Proper matching was obtained between current proposed spectrum design outputs and that for other analytical approaches.

The present drying beds of Al-Dubaiee waste water treatment station is not enough, thus, the present study is performed. In this work, many experiments have been made in order to find out the optimum thickness of the drying bed and to find suitable filtration agents from local materials. Moreover the effect of flocculent agents is tested. The results show that optimum thickness is 30 cm of brick and 25 cm of sand. Ferric concentration of 100 mg/l gives the best results. It is also found that drying efficiency is improved with reducing specific filtration resistance. The effluent waste water is found suitable for agriculture purpose concerned heavy metal concentration. Special drying bed (handy slop towards center) is constructed and it is found that the required area is reduced by 50%.

Published: March 2022

This study used the definitions of irrigation systems evaluation parameters: application efficiency; application adequacy and application uniformity, in addition to the storage efficiency, the deficit coefficient and deep percolation losses. It was adopted the linear distribution of the infiltration depths for cases that intersects the line of the distribution infiltration depths with the depth required in the root zone. It was determined a several equations for the expression of each of the storage efficiency and deficit coefficient first: as a function of both the application adequacy and application uniformity second: as function of both the application adequacy and application efficiency third: as function of both the application adequacy and deep percolation losses. These equations lead to ease of use and recruitment of these transactions, both in the evaluation of irrigation systems or follow-up infiltration depths within the root zone leaching of a particular crop during the growing season to find a function of productivity.

Published: March 2022

The effect of polypropylene fibers, steel fibers and hybrid polypropylene - steel fibers which consist of (50% polypropylene fiber+50% steel fiber), with various volume fractions 0.25%, 0.75% and 1.25% on the flexural behavior of Reinforced concrete T-beams under static load was investigated in this research.To carry out this research ten concrete mixes were prepared one for reference high strength concrete (without fiber), and the other contain all types and volume fractions of fibers. For eachmix three reinforced concrete T-beams, three cubes (150×150×150mm) and three cylinders (150×300mm) were casted. Water cement ratio was constant 0.38, silica fume with ratio of 10% as a partial replacement by weight of cement and super plasticizer with ratio of 3% by weight of the cementitious material were add to enhance the bond between fiber and cement matrix.28-day compressive strength and split tensile strength tests were made on hardened concrete specimen. The result showed that polypropylene fiber had little effect on mechanical properties of the high strength concrete. Compressive strength and splitting tensile strength of the steel fiber-reinforced concrete improved with increasing the volume fraction, achieving 24.5%, 43%, respectively, at 1.25% volume fraction. On the other hand, the addition of Hybrid fiber to high strength concrete improved compressive strength and splitting tensile stress with slight decrease as compared with the best improvement.All of the reinforced concrete T-beams were tested in flexure using controlled displacement two point loads applied on simply supported T-beams, during this test the load and deflection at mid span were measured. The result shows that the addition of polypropylene fiber had a little effect on the behavior of reinforced concrete T-beam at first steps of loading until yielding load, while, it was more effective in improving ductility and toughness (energy absorption) where the ultimate load and max deflection were increased with increasing volume fraction. The addition of steel fiber increased the cracking load, yield load and ultimate load capacity with increasing volume fraction, at the same time reduce deflection. The ductility improved by the addition of steel fiber, but this improvement decreased with increasing the volume fraction. The addition of hybrid fiber improved crack load, yield load, ultimate load, ductility and toughness at all steps of loading.

The fuzzy controller is one of the intelligent soft computing methods that realize a human being hierarchy sense and expert by building the program that realized it . In this work real time implementation of a fuzzy controller is realized by programming the industrial computer in c++ language. The performed fuzzy controller has two inputs and one output. The inputs are the speed error and change in error with controller output as PWM. The applied program architecture uses the matrix representation and subroutines for data entering the linguistic memberships for both error and change in error and performing rule-base in the inference mechanism using fuzzy logic . The output of the defuzification is pulse width modulation to the chopper drive circuit. The result shows good a fulfillment of the soft computing of the controller and with fast response and the effect of load as a disturbance on the shaft of the motor has been rejected quickly.
