Membangun Aceh Melalui Pendidikan (Studi Analisis Konsep KOPELMA Darussalam Ali Hasjmy)
Authors: Adil M.
Published: October 2020

This study aimed to investigate the background of the establishment of KOPELMA Darussalam, the concept of KOPELMA Darussalam proposed by Ali Hasjmy, and the relevance of Ali Hasjmy's educational thoughts with Aceh’s development through education. The study used a library research design, employing the primary data from Ali Hasjmy’s writings and the secondary data from two figures who had lived with and were close to Ali Hasjmy. The data were analyzed by using a descriptive analysis method. The results of the study revealed that Ali Hasjmy founded KOPELMA Darussalam as a manifestation of his educational, cultural, and political thoughts. This, in turn, gave birth to a big concept to Aceh’s development towards modernization, equipped with Islamic sharia, Acehnese culture and traditions, and science, after Aceh was hit by prolonged social conflict. The concept of KOPELMA Darussalam proposed by Ali Hasjmy intended to create KOPELMA Darussalam as a symbol of peace and love, a place to produce faithful and devoted humans to the religion and the nation, a place to establish science for humanity, a place to build "Pancasila"-instilled citizens, a symbol for the collapse of educational secularism and dichotomy of science in Aceh, a source of the realization of the Acehnese aspirations (i.e., of the ideals of justice and prosperity), an oasis of knowledge, and a manufacturer of people with devoted souls and spirit to the religion and the nation. To date, Ali Hasjmy's educational thinking about "The Ideal Concept of Darussalam (Abode of Peace)" is still relevant with the basis for Aceh's development through education.

This research is included in qualitative research by pointing to field research. That is research which focuses more on the results of data collection to informants who have been determined, the data sources used are primary and secondary data using qualitative data analysis. The results of the study show that divorce practices have taken place in Kuala Baru Subdistrict only through the village government, and rarely come to court. Then, the understanding of the Kuala Baru people about the giving of iddah is still very minimal, so they think that if they are divorced there are no rights and obligations of husband and wife. Therefore, based on the provisions of Islamic law the custom that occurs in the Kuala Baru community about the absence of a living iddah for a wife who is denied by raj'i is very contrary to Islamic law, even al-'urf also rejects the habits of the Kuala Baru community, and also the benefit is very detrimental to women, because their rights are not fulfilled.

Commercial Artificial Sweeteners Affect Spermatogenesis in Mice
Authors: Fatma Al-Qudsi  , Alaa Al-Dossary
Published: October 2020

The use of artificial sweeteners has increased in recent years. More young people are using them as a non- caloric sweetener in coffee or tea. They are also present in many manufactured food products such as biscuits and cakes. Many studies explored the potential biological effects of artificial sweeteners. However, most studies explored single types of artificial sweeteners, while very few were done on the actual commercial artificial sweeteners compounds present in the market and used the normal permitted daily dose. Spermatogenesis is one of the important biological functions that leads to the production of the male germ cells, the sperms. Studies showed that male infertility has increased in recent years. - The aim of this research was to study the effect of commercial artificial sweeteners on mouse spermatogenesis. Male albino mice were divided in two main  groups:  1.Control  group  and  2.Treated  group.  Each  group  was  then  divided  into  4  groups  (C1,C2,C3  and C4)  and (T1,T2,T3 and T4 ). Treated Swiss albino male mice were orally given 50mg/kg commercial artificial sweetener solution for four weeks. While the controls were given distilled water. Artificial sweeteners caused multiple malformations in spermatozoa such as a ring shape at the end of the sperm tail, coiled sperm, short tail and cytoplasmic droplet seen in the mid-piece compared to the controls. Alteration of spermatogenesis process was seen in treated testis histological sections compared to the controls, by the increased number of deformed seminiferous tubules, the shrinkage in their size and the disappearance of the membrane surrounding some of the seminiferous tubules causing their fusion. Our results showed that daily consumption of 50mg/kg of commercial artificial sweeteners affects the spermatogenesis process in mice and produces malformed sperms.

Introduction/Objective. Diabetic nephropathy leading to end-stage renal disease is a major health problem worldwide. Hemodialysis (HD) treatment is associated with glycemia variations. Diabetic patients on HD might benefit from a non-invasive online glycemia monitoring system. The aim of this study was to assess the glucose concentration from the matrix of the spent dialysate fluid using near-infrared (NIR) spectroscopy. Methods. Blood samples and spent dialysate were collected in the 15th minute of the HD treatment from 15 patients. The spent dialysis fluid was characterized by a NIR spectrometer in the range of 900?1300 nm. In order to apply the artificial neural network (ANN) and train it, the MATLAB NFTOOL program was used. The testing and training of the ANN were executed using the NIR spectrum of the spent dialysis fluid as input, and the glucose concentration as output. Results. A significant correlation in excess of 93% between the NIR spectrum of the spent dialysate and the blood glucose concentration (3?9 mmol/l) was found. Conclusions. NIR spectroscopy is a non-invasive and reliable method of glycemia monitoring which can be used in maintaining HD patients.

Litterær kompetanse i barnehagelærerutdanningen
Authors: Dyrkorn Fodstad Cecilie
Published: October 2020

Denne artikkelen søker å bidra med kunnskap om barnehagelærerstudenters litterære og didaktiske kompetanse, et fagområde det i liten grad er forsket på, selv om studentene som fremtidige pedagoger skal tilby et variert spekter av bøker og høytlesingssituasjoner til barna i barnehagen. Artikkelen bygger på en undersøkelse av hvordan fire studenter ved barnehagelærerutdanningen samtaler om og diskuterer tre ulike bildebøker, og forskningsspørsmålet er: Hvilke former for analytisk og didaktisk kompetanse om bildebøker kommer til uttrykk i tolkningsfellesskapet mellom studentene på barnehagelærerutdanningen? Basert på Örjan Torells (2001) operasjonalisering av litterær kompetanse i kompetanseområdene «konstitusjonell kompetanse», «utføringskompetanse» og «overføringskompetanse», viser denne undersøkelsen at studentene anvender både utføringskompetansen og den konstitusjonelle kompetansen i analysen av de tre bøkene, men på ulik måte. Overføringskompetansen anvender studentene først og fremst inn mot didaktiske refleksjoner, og de ser ut til å vektlegge denne kompetansen som en inngang til å engasjere barn i samtaler om bøkene. Et vesentlig funn er at når studentene i tolkningsfellesskapet danner en helhetsforståelse av en bok, synes dette å ha en medvirkende positiv effekt på hvordan de ser for seg boka i didaktisk sammenheng.
English abstract

Literary Conversations in Early Childhood Teacher Education
This article seeks knowledge about the literary and didactic competence of early childhood teacher students. This field is scarcely researched, although the students, as future educators, will offer a varied range of books and reading situations to children in preschool. The article examines how four students in Early Childhood Teacher Education talk about and discuss three different picture books. The research question is: What kinds of analytical and didactic competence about picture books are expressed in the interpretation community between the students in the Early Childhood Teacher Education? Based on Örjan Torell’s (2001) operationalization of literary competence in the areas of “constitutional competence”, “performance competence” and “literary transfer competence”, this study shows that the students apply both the performance competence and the constitutional competence in the analysis about the books, but in different ways. The literary transfer skill is primarily linked to didactic reflections, and the students seem to emphasize this competence as an input to engage children in conversations about the books. An important finding is that when the students in the interpreting community form a comprehensive understanding of a book, this seems to have a positive effect on how they envision the book in a didactic context.

Published: October 2020

Introduction. The selected research topic urgency is due to the need for a quick assessment of the condition and reliability of materials used in various designs. The work objective was to study parameters of the influence of the defect on the response of the surface of the medium to the shock effect. The solution to the inverse problem of restoring the radius of a defect is based on the combination of a computational approach and the use of artificial neural networks (ANN). The authors have developed a technique for restoring the parameters of a defect based on the computational modeling and ANN. Materials and Methods. The problem is solved in the flat setting through the finite element method (FEM). In this paper, we used the linear equations of the elasticity theory with allowance for energy dissipation. The finite element method implemented in the ANSYS package was used as a method for solving the boundary value problem. MATLAB complex was used as a simulation of the application process (ANN). Results. A finite element model of a layered structure has been developed in a flat formulation of the problem in the ANSYS package. The problem of determining unsteady vibrations under pulsed loading for different radius variations of the defect is solved. Positional scanning of the research object is applied. Graphical dependences of the vibration amplitudes of points on the surface on the defect radius are plotted. Discussion and Conclusions. As a result of studying the dependences of vibration responses on the defect radius, the authors have developed an approach to restore this parameter in a flat structure based on a combination of the FEM and ANN. The research has shown that the amount of data used is sufficient for successful training of the constructed ANN model and identification of a hidden defect in the structure.

Authors: Lagerev I. A. , Tarichko V. I. , Panfilov A. V.
Published: October 2020

Introduction. The paper considers the creation and application of digital twins at various stages of the life cycle of mobile transport and transshipment rope complexes (mobile ropeways), the equipment of which is mounted on the basis of wheeled or tracked chassis of high load capacity. The work objective is to improve safety in using such transport systems based on real-time forecasting of potential failures. This will prevent the occurrence of emergencies in a timely manner.

Materials and Methods. The structure of the digital twin of the mobile transport and transshipment rope complex is proposed. Approaches to the analysis of ongoing work processes in order to prevent accidents have been developed. They are based on simulation modeling of the system dynamics using new complex mathematical models built through the system approach.

Results. The developed method was tested on a large-scale layout of a mobile transport and transshipment rope complex created by 3D printing methods. A mathematical model of this system was developed; it was used to construct a digital double of the experimental model. The possibility of predicting failures in the layout is shown experimentally through the example of a rope slipping case. To do this, the actual value of the load suspension point coordinate obtained through the video stream processing method was compared to the predicted value calculated using a digital twin.

Discussion and Conclusions. The research results provide the creation of an industrial digital twin of a mobile transport and transshipment rope complex mounted on cross-country wheeled chassis.
Physicomathematical modeling of the formation features of fillet welds of bridge metal structures under submerged-arc welding
Authors: Mosin A. A. , Erofeev V. A. , Sholokhov M. A.
Published: October 2020

Introduction. The weld formation under the submerged-arc welding of bridge metal structures is investigated. The work objective is to study possibilities to increase the welding performance during the arc welding of fillet seams.

Materials and Methods. Methods of computer analysis are used to optimize the technology. With their help, a physicomathematical model of fillet weld formation under the submerged-arc welding has been developed. It is based on a system of equations for thermal conductivity and equilibrium of the weld pool surface. In this system, the formation of an arc cavern is determined through the flux boiling isotherm under the action of the arc column radiation; heat transfer by the flux vapor inside the arc cavern and the influence of the spatial position on the formation of the weld pool are taken into account.

Results. New mathematical relationships that describe physical phenomena under the submerged-arc welding of fillet welds are proposed. The key feature of the proposed model is in the fundamental difference between the submerged-arc welding and the gas-shielded arc welding, i.e., during submerged-arc welding, the arc burns in a gas-vapor cavern that appears due to the melting and evaporation of flux. Numerical simulation of the temperature distribution during production of the fillet welds in 1F and 2F positions is carried out. The process constraints under the single-run welding of the fillet welds are specified. It was determined that the single-run submerged-arc welding of fillet welds in 1F position exhibits high-quality formation of welds for almost the entire range of metal sheet thicknesses. During production of fillet welds in 2F position, high-quality formation is provided only for sheet thicknesses up to 8 mm. At heavy thicknesses, the formation of the seam is disrupted due to the melt flow from the vertical wall. In this case, the leg length decreases; a typical undercut is formed; so the weld will be asymmetric and less strong.

Discussion and Conclusions. Comparison of the numerical analysis results with actual data on welding modes under the production of bridge metal structures shows that the existing fillet welding technologies have already reached their maximum efficiency rate. Further productivity gain is possible by forming oversized legs only with multiarc or multielectrode welding methods.
