Peace of mind is a very universal expression of happiness experienced by people. Peace of mind has a very strong bond with dhikr, which is a verbal and spiritual worship activity that is expressed by saying certain sentences using the heart to mention Allah's name without an outward sound. The purpose of this study is to find out the method of practicing the Qadiriyah Naqsyabandiyahi Order and the impact of remembrance of kahfi on peace of mind for the practitioners of the Qadiriyah Naqsyabandiyah Order in Air Limau Village. This research method uses descriptive qualitative research methods, with data collection techniques, namely by observation, interviews, and documentation. The results of this study indicate that the Qadiriyah Naqsyabandiyah Order is a combination of two orders, namely the Qadiriyah Tarekat and the Naqsyabandiyah Order. The Qadiriyah Naqsyabandiyah Order was founded by Sheikh Ahmad Khotib Syambas Ibn Abd.Ghaffar al-Sambasi al-Jawi (d.1878 AD) in 1857 AD. The procedure for the congregation is by coming to a murshid to take bai'at or making a promise to practice it. the teachings of the Qadiriyah Naqshbandiyah Order. The activities of the Qadiriyah Naqsyabandiyah Order by practicing the remembrance of Jahar, remembrance of khafi, khataman, manaqiban, riyadoh, and pilgrimages to the tomb of Mursyid. The visible impact when finished dhikr khafi is that it can cause a sense of energy in the soul, relieve stress, be solemn in worship, be passionate about worship, and always surrender to Allah for all trials or calamities and tests that come from Allah SWT.

Τhe Turkish Nominal Syntagmatic Sets 'Ad tamlaması': A Linguistic Approach in Turkish Second Language Acquisition and Teaching
Authors: MAVRİDOU Vasiliki
Published: January 2023

This paper investigates the second language (L2) acquisition of the Turkish category Ad tamlaması (AT). AT consists an umbrella term which is encountered in Turkish grammars and L2-Turkish coursebooks to refer to three forms of Nominal Syntagmatic Sets (NSS), namely a) N-(n)In N-(s)I(n), b) N N-(s)I(n) and c) N N-(y) . This paper is trying to examine whether the apparently formal similarity of these 3 Nominal Syntagmatic Sets Ad Tamlaması (NSS-AT) in Turkish can be correlated with a respective degree of ease in L2 acquisition and simultaneity in L2 teaching or not. The main aim of this paper is to delineate the differences of these three NSS forms by testing them upon 12 morpho-syntactic criteria. The test results will show how much syntactically analytic and semantically transparent each of these sets is. We will conclude that the formal differentiation of the 3 NSS types does not always correspond with functional- semantic differentiation, which has implications on the difficulties these forms create in L2-learners. We will show that in the L2 learning process of the 3 NSS-AT forms, we expect a learning step ahead in the analytic N-(n)In N-(s)I(n) form compared to non-analytic compounds such as the N N-(s)I(n) form and more blurred cases such as the N N-(y) form, which shares properties of both Noun Phrases (NPs) and compounds. From a didactic scope, we come to assume that the traditional interconnection of the three NSS-Ad Tamlaması forms in Turkish L2-teaching and L2-learning methods should be put aside and rather give its place in alternative more anti-holistic approaches which would uncover the hidden syntactic properties of the 3 forms rather than stress the similarities between them.

Published: January 2023

The earthquake and tsunami disasters in Aceh Province, Indonesia led to several injuries, deaths, unfound bodies, and high property losses on 26 December 2004. This hazardous period has reportedly become a valuable case for Syiah Kuala University, where various solutions are being considered for eradicating subsequent occurrences. Therefore, this study aims to determine the implementation patterns of the disaster curriculum developed and applied at Syiah Kuala University, to achieve a DPC (Disaster Preparedness Campus) reputation and enhance DP (Disaster Preparedness) among community members, especially students. A qualitative verification method outlined as a description was used, due to being an inductive approach to the entire experimental process. Data collection was also carried out through observation and literature review, as well as several interviews with the following, (1) The head of the technical implementation unit general course of Syiah Kuala University, (2) The coordinator and lecturer of disaster and environmental knowledge course, and (3) The students of Syiah Kuala University studying the course. After this process, a Delphi method was used to analyze the data obtained, with the outcomes confirmed by a competent expert. Based on the results, three important steps were found to improve disaster preparedness among the people of Aceh and Syiah Kuala University students, namely (1) The establishment of the Tsunami Disaster Mitigation Research Center in 2006, (2) The establishment of the Master Program Study of Disaster Science in the university's Postgraduate Program in 2010, and (3) Development of the general course of disaster knowledge and environment in 2016, which was a compulsory requirement for all students from various faculties, departments, and programs. This indicated that Syiah Kuala University was the first campus to mandate a disaster science course in Indonesia. These results are expected to improve disaster preparedness for students, with Syiah Kuala University becoming a DPC (Disaster Preparedness Campus) in Indonesia.

Nos processos formativos de professores, a dinamização de vivências lúdicas constitui-se uma estratégia teórico-metodológica na ação de ensino-aprendizagem dos fundamentos da educação infantil no âmbito da formação e prática docente de futuros professores que se encontram com o outro nos espaços da universidade e da escola de educação básica para compartilhamento de saberes, experiências e aprendizagens da docência. Esses momentos serão narrados neste relato de experiência que tem por objetivo analisar os sentidos da dinamização de vivências lúdicas na formação e prática docente de futuras professoras que participaram das diferentes metodologias de ensino-aprendizagem utilizadas nas aulas de Pesquisa e Estágio em Educação Infantil pelas professoras formadoras desse componente curricular, pela bolsista de ensino e pelas estudantes do 6.° semestre do turno matutino do curso de Pedagogia do Departamento de Educação (DEDC) de Guanambi, Campus XII da Universidade do Estado da Bahia (UNEB), no primeiro semestre de 2018. As vivências lúdicas durante as aulas constituíram-se em um importante momento de reflexão sobre como as acadêmicas poderiam pensar seu planejamento para as crianças da educação infantil, etapa na qual teriam que realizar as atividades de estágio. É importante pensar a formação docente a partir da relação teoria e prática, do trânsito entre universidade e educação básica, da indissociabilidade dos saberes curriculares, acadêmicos e experienciais.
A percepção dos estudantes cotistas sobre os currículos dos cursos da Universidade Federal do Rio Grande do Sul com maior densidade entre vagas e inscritos
Authors: Silva Thalles Ricardo de Melo , Lui Lizandro
Published: January 2023

O artigo se inscreve nas discussões sobre as ações afirmativas nas Instituições de Ensino Superior (IES). Tendo como universo de estudo a Universidade Federal do Rio Grande do Sul (UFRGS), o objetivo é analisar de que modo o estudante cotista percebe o currículo dos cursos com maior densidade entre vagas e inscritos. No estudo, entende-se o currículo como um elemento construído historicamente como um mecanismo institucional de reprodução social. Por outro lado, a percepção dos estudantes cotistas está relacionada ao seu habitus, que é constituído por variáveis econômicas, sociais e culturais. Utiliza-se o estudo de caso como abordagem metodológica. Mediante entrevistas aprofundadas, entrevistaram-se 5 estudantes dos cursos com maior densidade da UFRGS. Três razões nortearam a análise sobre a percepção curricular: a densidade do currículo, a composição deste e a avaliação. Por mesclarem uma rotina de trabalho e estudos devido à situação socioeconômica, os cotistas entrevistados percebem o currículo como denso. As variáveis educacionais, por outra via, influenciam as avaliações, que geram dificuldades, principalmente, no início do curso. Por fim, a composição curricular é resultado de uma seleção, que exclui algumas vivências do público cotista. Embora essas razões levem à identificação de mecanismos de reprodução, por meio do ingresso do público cotista, há conflitos que permitem a possibilidade de mudança institucional.

Introduction: Asthma is heterogenous disease characterized by chronic airway inflammation. COVID-19 pandemic has an impact on health services where telemedicine could provide alternative method to evaluate patient’s condition, reduce risk of infection and disease transmission. The aim of this study is to analysis knowledge, asthma symptoms control and risk factors among the asthmatic patients via telemedicine
Methods: Data was obtained from telemedicine of 28 asthmatic patients in the context of community services. Inclusion criteria is stable asthmatic patients who conducted medical interview via videocall application. Cross sectional data were taken including demographic, knowledge of subjects, profile of subjects, and assessment of asthma symptoms control and assessment of poor outcomes. Data were analyzed descriptively and variables were analyzed using chi-square.
Results: Subjects consisted of 28 stable asthmatic patients. The average of asthma onset was 17.96 years old. Clinically profile showed that 67.86% subjects were not routinely controlled, 64.29% had never performed pulmonary function test, 67.86% subjects didn’t know the level of asthma control symptoms. Evaluation based on GINA symptoms control only 39.29% were in good control condition, 35.71% were partially controlled and 25% in uncontrolled condition. Use of inhaler device recently or previously prescribed on 67.86% subjects. Evaluation of knowledge about asthma still unsatisfactory, 67.86% subjects didn’t know about their modifiable risk factors, 96.43% didn’t know about written action asthma plan, 60.71% didn’t know about asthma exercise. Self-medication was associated with poor asthma control (p=0,036) and knowledge about modifiable risk factors related to asthma symptoms control (p=0,041).
Conclusion: Self-medication is related to uncontrolled asthma and knowledge of modifiable factors is related asthma symptoms control. It is important to educate the patient about the modifiable risk factors of asthma and how to manage it. Patient knowledge about their disease is still lacking, and there is a need for ongoing education to achieve good asthma control. Alternative intervention through telemedicine especially for continuing education and may therapeutic strategies can be performed as an effort to obtain well controlled asthma in community. Telemedicine, particularly in asthma management may benefit as an alternative approach of healthcare service in the context of pandemic era.

Abstract: Fecal sludge can be treated by conventional treatment such as pond stabilization which is commonly used to reduce organic concentrations. However, nutrients such as NH3 are still widely measured in the effluent. One of the sewerage treatments in the city of Jakarta, for example, experienced this condition. This study aims to design an appropriate technology to increase the efficiency of nutrient ammonia and total suspended solid (TSS) removal at Duri X IPLT. The unit added in the selected effluent treatment is Granular Activated Carbon (GAC). Design considerations are the characteristics of activated carbon, operating conditions (discharge and contact time), and operating mode (fixed-, expanded-, or fluidized-bed, pumped, or gravity flow). The Carbon Usage Rate for removing ammonia and TSS is 1.384 g/L and 0.378 g/L, respectively. Maintenance is required so that the granular activated carbon (GAC) unit can continue operating and functioning properly. Blockages in carbon transport pipes can occur in many pipes. This can occur due to a too-small pipe, a short bend radius of the pipe, a lack of speed, and a lack of cleaning of the pipe. The eroded pipe is also a common problem that often occurs in unlined mild steel and fiberglass reinforced plastic (FRP), usually in sharp bends.

METHOD OF FORECASTING THE DIRECTION OF PROCESSING HYDROCARBONS
Authors: Sater Nabil Abdel , Grigorov A.
Published: January 2023

In the article it is offered to rationalize work of installations on processing of hydrocarbonic raw materials, at the expense of its classification on types, using criterion of forecasting (KP) of the direction of processing. This approach will generally contribute to the rational use of technological equipment, reducing the metal consumption of devices and processing schemes, reducing energy costs by recovering excess heat and reducing heat exchange with the environment, efficient use of pumping equipment. At the same time, the general culture of production will increase and the harmful load on the environment will be reduced. Experimental studies have shown that the relative dielectric constant (ε), kinematic viscosity (ν20, mm2 / s) and Conradson coking (хk,%) of hydrocarbons, significantly depend on its chemical and fractional composition. In view of this, the proposed CP should be based on the above indicators. Experimental studies have allowed determining certain limit values of KP in accordance with which, hydrocarbons can be attributed to a certain type: type 0 –; type 1, 2 –; type 3 –; type 4 –.

On the basis of the calculated values of KP, in the future, it is possible to develop rational schemes of technological processing of hydrocarbons, which will be related to the fuel, oil and combined direction (option). Depending on the needs of certain types of petroleum products, the target components obtained in the implementation of these schemes are hydrocarbon gases, motor and boiler fuels, lubricating oils, petroleum coke, bitumen, by-products – degradation gases, paraffin, resins and asphaltenes.
FEATURES OF THE APPLICATION OF HEAT STORAGE ELEMENTS WITH A PHASE TRANSITION IN THE REGENERATIVE HEAT EXCHANGERS OF GLASS FURNACES

Published: January 2023

Increasing the air temperature in regenerative heat exchangers is one of the most effective means of increasing the efficiency of glass furnaces and reducing their fuel consumption. The value of losses with flue gases in furnaces remains quite high and amounts to 25–40 %. As a result, the question arises in the modernization of flue gas utilizers of glass furnaces, the purpose of which is to increase the amount of heat extracted from flue gases without a significant change in overall dimensions, as well as the aerodynamic characteristics of heat exchangers. One such measure is the use of heat storage elements with a phase change in the packing of regenerators. A feature of such materials is the presence of «residual» heat of the phase transition, i.e., such a packing will receive and transfer more heat by this amount compared to the traditional one. However, when solving this problem, the question arises of choosing a fusible material that satisfies the operating conditions of the packing of regenerative heat exchangers of glass furnaces. The paper analyzes the thermophysical properties of some inorganic substances, the characteristics of which make it possible to use them as a fusible material for packing elements. However, at the moment, inorganic compounds of barium sulfate BaSO4 and sodium sulfate Na2SO4 in combination with magnesite and periclase refractories have acquired practical use for high-temperature installations (regenerative heat exchangers of blast-furnace metallurgical production). Such materials have shown good thermal stability and stability under thermal cycling. The study of the possibility of using materials with a phase transition for heat storage elements of packings is associated with the need for mathematical modeling of complex heat exchange processes in the working space of regenerative heat exchangers under conditions of a quasi-stationary mode of their operation. Therefore, the final conclusions about the effectiveness of the modernization of regenerative heat exchangers by using packing with a phase change can only be made based on the results of additional studies, which will determine the influence of a whole complex of various factors that affect the performance of heat storage elements of this design.
Numerical modeling of the processes of irreversible deformation of rings under explosive loading
Authors: Tatarinova Oksana , Breslavsky Dmytro
Published: January 2023

the quasi-static problem is discussed. The equations of the incremental theory of plasticity are used to describe fast deformation. The numerical simulation method is implemented based on the use of the Arbitrary Lagrange-Euler (ALE) approach, in which the sequence of boundary value problems in the current configuration of the solid is solved using the Finite Element Method. An axisymmetric finite element of a triangular cross-section was used for modeling. The main system of equations is presented, which, when using the Finite Element Method, describes the deformation of axisymmetric bodies in the current configuration. At each stage of the calculation in the current configuration, the initial problem is solved numerically using the finite difference method. When the limiting value of the strain tensor components is reached, according to the ALE algorithm, the finite element model is rebuilt with the implementation of new boundary conditions. To build a computational model, the RD program was used, in which a two-dimensional model of a section of an axisymmetric body is surrounded by a mesh of special elements. A presented approach for the implementation of the specified boundary conditions of an axisymmetric body in finite element modeling is discussed. Calculations of irreversible deformation were carried out in a program developed on the basis of using the FEM Creep software package in the case of finite strains. Comparison of the numerical simulation data with the experimental results of other authors, obtained in the investigations of the explosive loading of aluminum rings set on a sphere, is presented. The experimental data are processed and the constants included in the constitutive equation, using the hardening law, are determined. Satisfactory agreement between the calculated and experimentally obtained values of the radial strain of the rings at different times is shown.

Published: January 2023

To investigate nonlinear bending of the functionally graded (FGM) plates with complex shape and resting on elastic foundation a variational-structural method (RFM) is proposed. Mathematical statement of nonlinear boundary value problems of plate bending is carried out in the framework of the classical geometrically nonlinear plate theory. To solve a sequence of linear boundary value problems obtained as a result of the linearization of the original nonlinear system of equations by the method of successive loadings and the Newton method, the method of R-functions was applied. Testing, as well as comparison of the obtained results with the results of other authors, made it possible to establish the reliability and effectiveness of the developed approach and apply it to study the stress-strain state (SSS) of thin plates with complex shape. A computational experiment was carried out for thin hexagonal plates with mixed boundary conditions for various types of external load and elastic foundation characteristics. The relationship between the greatest deflection of the plate and the load is obtained. The results are presented in the form of graphs.
Elastic properties and strength criterion of reinforced composite
Authors: Bohatyr Mykhailo , Lvov Gennadiy
Published: January 2023

Woven composite materials are increasingly being used in various fields of modern technology. Unlike composites reinforced with straight fibers, they have a higher shear stress loading strength and improved impact strength characteristics. Woven composites have good technological properties. Blanks with carbon or glass fabrics are well laid out on tooling in the manufacture of thin-walled structural elements of complex shapes. The technological advantages of woven composite materials have determined the economic feasibility of their widespread use in the aviation industry and the automotive industry. The paper presents a numerical method for identifying the elastic and strength characteristics of woven carbon fiber based on the results of a micromechanical analysis of a representative volume based on the known properties of the matrix and fibers. Numerical experiments on uniaxial tension in the x, y, and z axes directions have been carried out. Modeled shift in three coordinate planes. The strength characteristics of the representative volume of the composite under conditions of tension and compression in three directions, shifts in three planes, and three biaxial tensions are determined.
STRESS ANALYSIS IN A CONVEYOR BELT FOR THE MAXWELL MODEL OF ELASTIC ELEMENT
Authors: Pihnastyi Oleh , Sobol Maksym Olehovych
Published: January 2023

The mechanism of propagation of longitudinal dynamic stresses in a conveyor belt, the material of which corresponds to the Maxwell model of an elastic element, is considered. The features of the occurrence of longitudinal vibrations in the material of the conveyor belt for the section of the transport system equipped with asynchronous motors are considered. It is shown that the acceleration of the conveyor belt occurs as a result of an abrupt change in the traction moment of the asynchronous electric motor when the power consumption of the conveyor section changes. The process of acceleration/deceleration of the conveyor belt is periodic and is determined by the uneven distribution of material along the transport route. This imposes additional restrictions on the synthesis of algorithms for optimal control of the conveyor belt speed. Accounting for uneven distribution of material along the transport route is based on an analytical PiKh-model of the conveyor section. To analyze the longitudinal vibrations in the conveyor belt section of the transport system, the wave equation is written and the boundary conditions are substantiated. An estimate of the propagation velocity of longitudinal vibrations in the conveyor belt is given. A solution of the wave equation based on the method of successive approximations is obtained, which determines the dynamics of the propagation of dynamic stresses along the conveyor belt. An estimate of the value of the characteristic acceleration time of the belt, which determines the continuous mode of operation of the transport conveyor section, is given. The scientific novelty of the results obtained lies in the improvement of the control systems for the flow parameters of the transport system in the presence of restrictions associated with the occurrence of longitudinal vibrations in the conveyor belt. The practical significance of the results obtained lies in the construction of a methodology for calculating the limitations of the acceleration/deceleration mode of a conveyor belt unevenly loaded with material along the transport route.

Published: January 2023

Strength indicators determination of mechanical pedals structural components of vehicles, in particular the elements of their fastening to the corresponding locations cable drive, is relevant due to the need to comply with the requirements for maximum efforts in accordance with UNECE Regulations No. 13 and No. 35 on the one hand and ensure a sufficient margin of safety according to the technical operating conditions cable drives - on another hand. The topic considered in article acquires additional practical benefit from the point of view of assessing the margin of mechanical pedal components safety under critical operating conditions, which are the basis of boundary conditions in the formation of the task - strength analysis of certain parts by the finite element method in ANSYS environment.

It should be understood that the above analysis is only one of mandatory stages of pedal simulation tests, because, being a relatively simple unit, a mechanical pedal really must be designed in such a way that critical loads should destroy the least critical replaceable elements of the assembly, but not the drives and their corresponding aggregates activated via remote control cable.
A universal algorithm for linear and quadratic programming in the problems of contact deformation of cable-stayed structures with one-way connections
Authors: Grischenko Volodymyr
Published: January 2023

Problems in production activities that require optimization problems are extremely numerous and very diverse. Optimization approaches are most often associated with the search for the best version of a structure or building. Mathematical methods for solving such problems are developing rapidly and are widely used. They actively and productively penetrate into many areas of scientific research, into engineering and design developments, are an important tool for improving design efficiency throughout the entire process of creating structures. The search for the best design solution is reduced to the selection of a set of parameters that provide a stationary value of the objective function. A wide range of extreme problems of practical orientation, as a rule, in mathematical models contains restrictions on design parameters of the equality-inequality type. In general, their set makes up the content of such a section of mathematics as Mathematical Programming. Due to the fact that there is no single solution method, diversity in research approaches has formed, which divides them into groups, classes, etc. Linear programming (LP), as one of the sections, with a linear objective function and constraints is well studied and successfully applied. Methods of solving problems of nonlinear programming, which includes quadratic programming, are more complex. Therefore, the development of convenient computational schemes is relevant. The essence of this work is that the statements of 2 optimization problems are formalized in a single and convenient form of a symmetric matrix dependence, which makes it possible to obtain an effective (in our opinion) algorithm for their implementation. Namely, a unified scheme for solving both LP and KP problems based on matrix algebra operations is proposed. Quadratic programming (QP), as the second section, also has wide possibilities, in particular, it allows considering the practical tasks of calculating VAT in the mechanics of a deformed solid body under the conditions of contact interaction. Such problems, in particular, include cable-stayed structures with one-way connections and span lengths that can reach tens or hundreds of meters. As an example, the behavior of a model cable-stayed span structure under varying wind loads is considered. The given results may be of interest.
On the modeling of boundary conditions for determining the critical speeds of rotation of rotors
Authors: Trubayev Oleksandr , Larin Andrew
Published: January 2023

The article is devoted to the definition of boundary conditions that allow achieving adequate results when calculating the critical speeds of rotation of rotors based on finite element models. Experimental determination of the frequencies of free vibrations of a laboratory rotor on ball bearings was carried out using a vibration measuring complex developed by the authors. Numerical studies of the free vibrations of a laboratory rotor and a cylindrical pipe with a wall thickness to length ratio of 1/10 were performed on the basis of a three-dimensional finite element model under various boundary conditions. Movable and fixed cylindrical hinges corresponding to floating bearings are used as supports in the calculation scheme of the laboratory rotor. Due to the fact that the dimensions of the bearings along the length of the shaft are small compared to the total length, it is assumed in the calculation model that the shaft is hinged along the edges at separate points of one circle on each bearing. Shaft mounting options at two, four and eight points are considered. The options for fastening a cylindrical pipe in the extreme sections at two points, a quarter of a circle and a full circle are considered. Comparison of experimental and numerical results, solutions obtained analytically and on the basis of the finite element method is carried out. An analysis of the modes of natural vibrations showed that with various options for fixing a cylindrical pipe, vibration modes arise associated with the deformation of the pipe as a shell. For example, when fixing a pipe along a quarter of a circle, among the forms №1-№10, only the second corresponds to the deformation of the pipe as a beam. The results of the study of free vibrations of a laboratory rotor show that the best option for boundary conditions, which makes it possible to approach the results of the experiment, is fastening on each bearing at two points located on the neutral line of the cross section when the rotor is bent. Numerical studies of the eigen frequencies of a cylindrical pipe show that it is with this type of boundary conditions that one can obtain results that are closest to the analytical solution.

Published: January 2023

Learning activities at the Creative Media State Polytechnic after the pandemic period, especially in the design department of the game technology study program, were held in blended learning. Blended learning is the right choice of learning because it needs adaptation from lecturers and students, where previously learning was held fully online, now it is held online and offline. Blended learning activities can be very effective and efficient in their implementation if the learning process is well prepared. One of the learning activities carried out is independent learning activities. Therefore, this study aims to produce a learning application that can be used as an independent learning module so that students can learn without being assisted by anyone just by using this independent learning module. The approach taken is the ADDIE development method. The ADDIE development model consists of five stages, namely analysis, design, development, implementation, and evaluation. Expert response to this learning application is a crucial thing to do. This application is evaluated by an expert with a background in graphic design, learning media, and communication. The independent learning module application was successfully developed and implemented in semester 3 of the 2-dimensional game programming course.

Thiagarajan using 4 stages, namely: the definition stage (Define), the planning stage (Design), the development stage (Develop), the dissemination stage (Disseminate). The research sample was class XII students totaling 38 students. Research instruments include questionnaires and needs analysis in this study using observation, interviews and questionnaires. The technique used in the analysis of this research data is quantitative descriptive analysis. Learning media using Canva can increase student learning motivation. The use of this media is very effective, both offline and online. The development of Canva learning media is also based on phenomena in the field, namely that there has not been development of learning media using Canva for use at MAN 1 Pontianak, as a result it is necessary to develop learning media using Canva that are valid and practical. The purpose of this study is to share learning media using Canva which is used at MAN 1 Pontianak. It is hoped that this learning media can be used by teachers, especially guidance and counseling teachers for learning in advanced study material classes.

During the Covid-19 pandemic, the trend of blended learning increased rapidly. The Indonesian government provides various supporting facilities for blended learning, one of them is a learning account. Unfortunately, this surge in demand for and provision of supporting facilities has not been matched by sufficient skills to properly organize online learning. Many teachers do not know how to utilize ICT in learning. The author took the initiative to develop teacher professional development activities to improve digital skills. These activities were developed using the technological Pedagogical Content Knowledge (TPACK) and using the Analyze, Design, Develop, Implement, Evaluate (ADDIE) model. It can be concluded that these activities can be duplicated again with some adjustments. First, this training is suitable for teachers at the K12 level. If it will be used for PAUD/TK teachers, this training needs to be redesigned. Second, it would be much better if the institution where the teacher works provide dedicated hours for professional development which are also counted into teaching/additional teacher hours.
