Irregularity of geometric and physical parameters in thin-walled structures leads to significant concentrations of stresses and creates dangerous zones for the spread of cracks or plastic deformations. Under the influence of a tense state, they are similar to gills. Stress concentration zones in areas of irregularity have a significant impact on the tensile strength and durability of thin-walled structures. Traditional analytical and numerical methods known at this time are less effective in investigating the stress-strain condition of corrugated thin-walled structures. It is, therefore, necessary to develop new effective methods for solving the tasks of this class. Currently, for engineering calculations, there is virtually no comparison of simple and convenient formulas for determining the critical compressive load taking into account the peculiarities of the design. The scientific novelty of the paper is that to achieve the set goal, it will be used for the first time in the general theory developed for the calculation of buildings and structures, known as the "Theory of elasticity in ordinary differential equations." The paper will show that the accuracy of this new theory is adequate to the classical elongation theory and at the same time dramatically simplifies the solution of any problem in the calculation of tiles, which is achieved by converting them to conventional differential equations. The general methods of compiling differential equations, the methods of its simplification, for the calculation of membranes with cross-sectional incisions, and the calculation of plates under conditions of nonlinear deformation are discussed. Methods for solving differential equations with variable and momentum coefficients are specified. An algorithm and a program for the analysis of the stress-strain state of spatial structures and their elements are developed. The practical value of the paper lies in the possibility of using developed methods and programs for the design and construction of buildings, as well as for the stability tasks of slabs with holes, and panels used in construction as typical assembly elements. The given mathematical algorithm and program for specific tasks, which are distinguished by simplicity, can be used by design and research organizations in the calculation and design of plates and membranes.

The Lesser Evil: Plutonium-239 or Uranium-235? A Study on F0 Atomic Bomb Survivors
Authors: Lin Yuhui
Published: December 2023

‘All models are wrong, but some models are useful.’ Radioactivity is a life-detrimental exposure that increases individuals’ susceptibility to cancer onset. The plasticity of the aging rate, expressed as d(log μ(x))/dx, has been informally acknowledged, often conflated with mortality rate μ(x) or risk log μ(x). A formal examination of this plasticity is lacking. The mortality schedule of irradiated F0 atomic bomb survivors in Hiroshima (U-235) and Nagasaki (Pu-239) at age exposure 40 - 45 (ATE45) can unveil the characteristics of hazard trajectories by isotope type and dosimetry. Based on the advantage derived from background radiation, an alternative population was employed during the comparative study. A dose-dependent relationship between radioactive isotope types and the rate of aging was presented in the frailty framework; _γ-Gompertz-Makeham_. Among survivors within the 0-5mGy range, an apparent pseudo-benefit initial mortality risk, linked to the distance from the epicenter, implies that mortality selection is influenced by both impact severity and natural frailty. Moreover, the standardized mortality ratio indicates a more pronounced impact of Pu-239 on age-specific mortality trajectories compared to U-235. In the 0-5mGy range, Pu-239 shows 11% (M) and 37% (F), while U-235 exhibits 4% (M) and 0.5% (F). Upon intense radiation exposure, variation in the human rate of aging exists within a 10-km radius from the epicenter, and gender sensitivity may be a significant contributor to mortality selection.
A note on Hempel’s paradox
Authors: Di Prospero Alfonso
Published: December 2023

In this paper, Hempel’s paradox is revisited, a paradox that arises from the observation of a black raven which inductively confirms the generalization “All ravens are black”, but can also be interpreted as supporting the statement “All swans are white”. The proposed resolution leverages the non-monotonic nature of inductive inference, suggesting that two distinct inferences from the same observation are not required to yield the same outcome. This exploration underscores the importance of the non-monotonic nature of induction, hinting at its reflection of the contextual and situated nature of human knowledge. There are many underlying epistemological questions that I do not consider here for the sake of simplicity. I have dealt with them in previous works. Of course all these remarks are only a sketch of a better developed theory that is still to be realized.

Manajemen Pendidikan Dalam Bingkai Otonomi Daerah (Analisis Terhadap Sistem Pendidikan di Daerah)
Authors: Ibrahim Mulyadi
Published: December 2023

Mengingat luasnya wewenang yang diberikan pemerintah pusat terhadap daerah dalam mengelola pendidikan sehingga banyak menimbulkan masalah khususnya dalam mengimplementasikan undang-undang No. 22 Tahun 1999. Ini menunjukan bahwa urusan pendidikan diserahkan kepada daerah dan daerah memiliki wewenang penuh dalam mengatur dan mengelola pendidikan yang ada di daerahnya, apakah ia pendidikan dasar maupun ke perguruan tinggi. Kendatipun demikian apakah benar pelaksanaannya sesuai dengan amanah undang-undang? Justru yang terjadi adalah sebaliknya. Masalah ini muncul terutama pada pendidikan tinggi terus beranggapan bahwa pemerintah daerah tidak ada wewenang dan mempunyai hak terhadap menajemen pendidikan tinggi, sehingga daerah tidak memperdulikan sama sekali terhadap keberlangsungan pendidikan tinggi. seharusnya daerah harus paham betul dengan adanya otonomi daerah maka otonomi pendidikan menjadi sebuah keniscayaan bagi daerah.

The creation of any structural element begins with the design of basic geometric parameters. In the article, the method of designing and determining the main elements of the structure of the main ribs of the wing with conditions of static strength were reviewed, and a method of three-dimensional parametric modeling was developed. The rib is one of the most important elements of the wing, which act significant flight loads, and the main ribs additionally act concentrated forces. The article analyzed the design features of the rib design of the wing of the transport category aircraft. An analysis of the current loads on the main rib was performed, shear and bending diagrams were determined. During realize high-lift devices, the aerodynamic flow of the wing changes significantly, which leads to a change in the stress-strain state of the wing. This relates not only to the increase in lift due to a change in the curvature of the wing and an increase in the wing area, but also due to a change in the position of the center of pressure relative to the chord of the wing. Therefore, to determine the loads, the aerodynamic characteristics, obtained by the numerical method in the ANSYS program, were used. In order to remain competitive, the aviation company needs to ensure the high quality of the manufactured equipment, its quick modernization and modification or change of the model series. The use of CAD/CAM/CAE/PLM systems at all stages of the life cycle of aviation parts, including the design and production stages, can significantly improve the quality of the created parts and reduce the cost of performing work related to design and production, while maintaining high rates of work. The method of three-dimensional parametric modeling of the main machined wing rib was developed using the Siemens NX computer integrated system, which allows to significantly reduce the stage of modeling typical elements of the aircraft airframe structure using the created three-dimensional parametric model of a typical structural element

According to the improved model of the thermal interaction of laser radiation and the processing material, a study of the change in the maximum temperature at different depths of the surface layer was carried out on the example of tool steel U12A. The rate of change of the maximum temperature and temperature stress as a function of the heat flux density of laser radiation (LV) was also studied. The range of LV density was taken within q=108...1011 W/m2 for different times of its action, which corresponds to the conditions for the possible occurrence of NS. The study of the dependence of the rate of change of the maximum temperature on U12A steel on the density of the heat flow at different depths showed that during all times of its action, rates of temperature change of more than 107 K/s are realized, which indicates that, according to this criterion, the formation of NS is possible over the entire range of densities heat flow and at all investigated depths. To determine the possibility of accelerating the formation of NS, the values of temperature stresses in the zone of action on U12A were calculated at a density of 108...1011 W/m2 at different depths with an action time of t=10-4 ...10-10c. Which showed that the direct formation of NS from the action of temperature stresses is practically impossible, however, at a time of 10-5...10-4 of their values, they approach those required at a heat flux density of 1011 W/m2. In order to determine the technological parameters that ensure the production of NS, spatial dependences of the volume of NS on the heat flux density and the time of its action were constructed for the radius of the spot R=10-6 m (Fig. 8) and R=5•107 m (Fig. 9) . It was determined that obtaining NS is more realistic for the size of the spot 5•107 m, although the probability of obtaining them is also low. In fig. 10 and 11 show similar dependences for the grain size on the heat flux density and the time of its action for the spot size R=10-6 m and R=5•107 m when acting on U12A tool steel. The obtained spatial pictures allow, knowing the required grain size, to choose the technological parameters that allow them to be implemented. All this will be required during the development of the technology for obtaining strengthening nanostructured coatings on the cutting tool.

Authors:   Kamyanets-Podilskіy National Ivan Ogііеnko University, Pidhirna Larysa
Published: December 2023

The purpose of the article is to research, reconstruct and analyze the personal biography of Mykola Zabello – a representative of the Ukrainian emigrant community, an em- ployee of the illegal residency of SC of UPR in exile “Istanbul Platform” and, at the same time, an agent recruited by the OGPU under the pseudonym “Nadiia”. The research methodology. To reconstruct the personal biography of M. Zabello, the author used biographical, prosopographi- cal, and retrospective methods, as well as the methods of deduction, analysis, and synthesis. In the course of the study, the principles of historicism, criticality, and systematicity were used in combination with the method of systematization, historical-genetic, and synchronous methods. The method of periodization and the historical-comparative method were applied. A special methodological role is assigned to the method of verifi cation of the source base. Th e scientifi c novelty of the research lies in the fact that, for the fi rst time in Ukrainian historiography, in the context of the activities of the Ukrainian exile special services, in particular, the “Istanbul Platform”, an attempt has been made to reconstruct and analyze the biographical world of one of its employees, M. Zabello, who was also the co-head of the Ukrainian emigrant community in Istanbul, one of its prominent fi gures, and a recruited agent of the OGPU. Th rough the prism of the personal biography of the agent “Nadiia”, the author examines the negative factors that had an impact on the success of the Ukrainian exile special services. Conclusions. Th is article, operating with a biographical typology, represents a study and reconstruction of the personal bi- ography of an employee of “Istanbul Platform”, an agent of the OGPU M. Zabello. By reproduc- ing the personality map of the agent “Nadiia”, the author explores the life narratives that formed his biographical world: mental, social, and religious characteristics that formed his personality: family status, political views, idealism, natural inclinations, the ability to adapt to new circum- stances, the ability to integration into a new society and facing challenges.
Military minister Oleksandr Rohoza: legislative and regulatory activities
Authors:   Pavlo Tychyna Uman State Pedagogical  University, Rohozha Mariya
Published: December 2023

The purpose of the study is determined by the need to research the existing source array of archives and publications to identify the directions of law-making and rule-making activities of Minister of War Oleksandr Rohoza (1858-1919) and his subordinate ministry ap- paratus for building the army of the Hetman State in the social and political conditions of its existence at the time. Th e research methodology is based on the principles of historical reli- ability, objectivity, systematicity, scientifi city, multifactoriality, and comprehensiveness; as well as the research methods: general scientifi c-analytical, synthetic, logical, classifi cation; histori- cal – problem-chronological, comparative-historical, historical-genetic, retrospective, periodiza- tion; interdisciplinary – source studies, archival studies, terminological analysis. Th e scientifi c novelty lies in outlining the activities of the Minister of War, the Ministry’s apparatus headed by him to regulate by laws and by-laws the structure of the military units created, the day-to- day activities of the army, and the organization of combat training in the diffi cult conditions of the formation of the Ukrainian State. Conclusions. Understanding the phenomenon of the era of the Ukrainian State, led by Pavlo Skoropadskyi, a professional military man, would be impossible without the importance of the formation of the army, as one of the main conditions for ensuring the progressive process of Ukrainian state-building. Th at is why the appointment of General Oleksandr Rohoza, an educated and experienced soldier, to the post of Minister of War, is considered causal. He initiated the organizational work on the creation of the Ministry’s apparatus; the appointment of professional military personnel to key positions provided the con- ditions for the law-making and rule-making process of the creation of the military. Th e mate- rial available in the archives and narrative sources on the meetings of the Council of Ministers gave suffi ciently convincing grounds for asserting the following. Th e Ministry of War, headed by Oleksandr Rohoza, its administration, and departments in the areas of activity, due to the avail- able opportunities, even due to the increase of socio-political instability due to various reasons, carried out work on the multifaceted legal and regulatory support of the creation of the army. Th is is confi rmed by the fact that during the days of the Ukrainian State, 48 draft laws and by- laws were developed, submitted for consideration, and transferred to the army in the diffi cult conditions of the growing political confrontation during 7 months.

Published: December 2023

The purpose of the article is to characterize the main activities of the Vinnytsia Pedagogical Institute based on archival documents, in particular, to analyze the personnel com- position, the state of educational activity and research work, to show the fi nancial situation of the institution in general, and the participants of the educational process in particular. Public-political and cultural-educational activities remained out of the author’s attention, which will be the subject of a separate publication. Th e methodological basis of the research is the principles of historicism, systematicity and comprehensiveness, problem-chronological and diachronic methods. Th e scien- tifi c novelty of the publication lies in the fact that for the fi rst time, based on archival materials of the fund of the party organization of the Vinnytsia Pedagogical Institute, the main areas of activity of this institution of higher education have been analyzed. Conclusions. Th e party organization of the Pedagogical Institute, in addition to ideological and ideological and educational work, tried to control other areas of the higher education institution’s work. At the meetings of the party bureau, personnel issues were considered, personal cases of party teachers who violated party discipline were heard, and the state of career guidance work and the progress of student admissions were analyzed. Th e subject of the discussion was the organization of the educational process: attention was paid to improving the quality of teaching, improving the pedagogical skills of teachers, using visualization in lectures, ensuring full-fl edged independent work of students, etc. Measures were taken to bring the activities of scientifi c and pedagogical workers closer to the practice of school- work and to improve the professional training of students. A number of documents characterize the state of the scientifi c work of individual teachers, in particular, their writing of theses, scientifi c and popular science works, etc. Th e material and technical base was expanded and strengthened: study areas increased, students received a new dormitory, a dining hall was put into operation, and some teachers received apartments. Most of these changes occurred in the 1960s. However, it was not possible to fully resolve the issue of providing the institute with an educational space, and teachers with housing, at that time.

Compare the infl uence of women “before” and “aft er” the war, what specifi c changes took place. The methodological basis of the research is based on the princi- ples of objectivity and historicism. During the research, comparative, analytical methods and the method of gender monitoring have been used during the research. Th e scientifi c novelty is based on the involvement of sources and historiography related to the participation of women in the struggle for obtaining voting rights in Great Britain during the Great War, the need to supplement modern Ukrainian research on this issue, to expand the knowledge base, is also im- portant. Conclusions. Th is issue is revealed with the help of documentary materials (memoirs, periodicals). On the examp le of specifi c female images of leading fi gures (in particular, Emmeline Pankhurst, Christabel Pankhurst, Nancy Astor and others), the features of the suff ragist move- ment, which operated in Great Britain before the beginning of the Great War and during it, are analyzed. Th e research used materials from newspaper periodicals from the time of the First World War, the original documents were translated in order to make the research accessible to Ukrainian historical science. The author investigated the participation of women in the political sphere and represented this process on a modern level. Th e methods of women’s struggle for suf- frage are revealed and the reactionary actions of British politics towards feminism are presented. The article analyzes the «Act on People’s Representation» issued in 1918, which granted women limited voting rights. Th e purpose of the article is to explore how the First World War af- fected women’s suff rage in Great Britain. British women were the fi rst to rise in the fi ght for suf- frage among European women. Their activism inspired other women to struggle as they sought to change their situation. Th e study of women’s history is one of the leading and important prob- lems in European historical studies, therefore, in the future, with the involvement of European and international experience and studying the practices of Western European gender studies, which studies will be relevant and widespread in Ukraine as well. Ensuring equality in Ukraine is an urgent problem that needs to be solved. Th erefore, the progressive experience of British women in the struggle for voting rights can be very useful.

The problem that often occurs in hospitals is that regulations related to hospital environmental health still need to be popular in the community. However, the development of technology and science has made agricultural tools and machines experience development and renewal and adapt to environmental conditions. Many types of fly control are available, such as fly traps in temporary garbage shelters in hospitals. This study analyzes operational needs and problems encountered by implementing fly trap technology in hospitals. This study consisted of three stages: budgeting, calculating the Kepner-Tregoe Situation Appraisal (KTSA), and the Kepner-Tregoe Potential Problem Analysis (KTPPA). The total operational costs required for this tool are IDR 887,496.00. Where this cost includes the component of preventing problems that must be faced in fly trap operations. Identification of tool constraints in operation consists of damage to the net on the fly trap, garbage piling up due to overloading in the garbage container, blockage of the entry path for flies to the fly trap, and the garbage collector coming into contact with the waste at the TPS. There are four potential problems in implementing fly traps that we previously identified, where there are possible causes, preventive actions, and contingent actions that can be taken to overcome these potential problems.

Sugar cane is a plant that is processed into crystal sugar because it contains high sugar content. Sugar production produces waste, one of which is molasses waste. This study aims to obtain molasses into a catalyst using the carbonization method and the sulfonation method. The sulfonation method uses variations in the concentration of 2, 4, 6, 8, and 10 N H2SO4 solution and variations in sulfonation time of 2, 4, and 6 hours to get the best molasses catalyst. Catalyst characterization includes surface acidity by acid-base titration, FT-IR, and SEM-EDX. This research also aims to produce biodiesel yield using the best molasses catalyst. The results of surface acidity analysis showed that the best molasses catalyst was obtained at 10 N H2SO4 concentration with 6 hours at 0.907 mmol/gr. FT-IR test results showed the presence of O=S=O functional groups at wave numbers 1149.74 cm-1 and 1038.57 cm-1. SEM and EDX analysis results showed that the molasses catalyst after sulfonation had smaller pores and more sulfur groups on the carbon sheet. The yield of biodiesel produced using a molasses catalyst was 84.51%.

Published: December 2023

Persons with disabilities are vulnerable, and their rights are often ignored. Persons with disabilities have the right to visit tourist sites. Bukittinggi City is a tourist city in West Sumatra Province. Its most popular tourist areas is the Jam Gadang tourist area and its surroundings, which include Jam Gadang, Fort De Kock Fort, and the Kinantan Wildlife and Cultural Park. People with disabilities are rarely seen in the Jam Gadang tourist area and its surroundings, both at tourist attractions and on the pedestrian paths connecting the three tourist attractions. This research aims to determine the fulfillment of accessibility for persons with disabilities in the Jam Gadang tourist area and its surroundings regarding tourist access and pedestrian access. Data was collected through field observations and questionnaires. The analysis was descriptive quantitative using scoring analysis. The result shows that the fulfillment of accessibility in the study area is generally "inadequate" and "not appropriate". Persons with disabilities have difficulties accessing tourist attractions and pedestrian paths. Facilities are available, but inaccessible, unaccommodating, unaffordable, and do not meet the expectations of disability groups. These physical barriers make it difficult for them to access study locations. The spatial exclusion hinders their participation in the tourism area.

Currently, almost every household in Indonesia has a motorbike, this is certainly a business opportunity. One of the most important components of a motorbike is the tire which functions to reduce vibration and protect the wheel from wear and damage. The business environment operating in the automotive sector needs to create high-quality goods or services to increase customer satisfaction. Costs in the company's productive processes must be reduced to achieve effectiveness. The object of this research is the XYZ Tire Workshop located in East Jakarta. In a day, the XYZ Ban workshop can provide up to 25 to 30 motorbike tire changes. Meanwhile, the workforce on duty is only 2 mechanics and the quantity of tools is limited. This causes delays and makes customers have to wait quite a long time before their motorbike can be worked on. The Single Minute Exchange of Dies (SMED) method which is included in lean tools is the key to reducing set-up process time. In general, SMED aims to standardize and simplify operating processes. The SMED technique is used as an element in Total Productivity Maintenance (TPM) in various studies to achieve lean manufacturing. Based on research data, the set-up time before implementing SMED was 177 seconds. After implementing the SMED method, the setup time was 126 seconds. This shows that the SMED method can reduce set-up time by 51 seconds.

Productivity is the most vital part of the food industry as it is one of the priority industries in Indonesia. PD. Saluyo is an industry that produces tofu, which needs to increase production efficiency to meet market needs. The problem in the tofu production process is the high waiting time during soybean soaking. The approach used in this research is lean manufacturing by mapping the process using Value Stream Mapping so that Value Added, Non-Value Added and Necessary Non-Value Added activities can be mapped. Further, Value Added, Non-Value Added and Necessary Non-Value Added data processing is weighted in VALSAT to determine the most significant waste and mapped through PAM. The mapping results obtained a VA of 3,29%, NVA of 90,64% and Necessary Non-Value Added of 6,06%. Based on the results of the VALSAT calculation, the most significant waste is found in time waiting and unnecessary motion. These results are re-mapped in PAM for further analysis using the Cause-Effect Diagram. The analysis results of PAM and the Cause-and-Effect Diagram proposed improvements to change the soaking process method using hot water and create a new SOP to adjust to the proposed production process. The results of the proposed improvements can increase the value added by 0,07% from 3,29% to 3,36%.

RISE 6.2 offers new perspectives on the Irish border. Bringing together contributions from different disciplines and cultural fields – history, political science, film studies, constitutional law and the theatre – it seeks to provide a multifaceted and complex discussion of a phenomenon that is all too often simplified in the political discourse before and after the 2016 Brexit referendum. Following the agenda suggested by the short film-essay Hard Border (2018), directed by Juliet Riddell and performed by Stephen Rea, this themed issue of RISE approaches the Irish border by differentiating between internal and external – Irish and Northern Irish, British and continental – perspectives and by exploring historical dimensions as well as contemporary engagements with a border whose increasing (discursive and material) invisibility following the Belfast/Good Friday Agreement of 1998 has been crucial to the ongoing peace process.
Лечение скученности фронтальной группы зубов на нижней челюсти системой прозрачных кап (элайнеров) с учетом параметров оптимальной формы зубной дуги пациента
Authors: Тимчук Я.И. , Титкова В.В.
Published: December 2023

Стабильность ортодонтического лечения повышается при сохранении исходного трансверзального размера зубных дуг в области клыков, и особенно на нижней челюсти. Достижению этой цели способствует использование современной ортодонтической конструкции – элайнер-системы.
Цель исследования. Определить наиболее информативные методы измерения диагностических моделей и тактику лечения сужения нижнего зубного ряда в переднем отделе c использованием элайнер-системы.
Объекты и методы исследования. Объект исследования – форма нижнего зубного ряда в переднем отделе. Исследование проводилось на базе кафедры ортодонтии БГМУ. Обследованы и приняты на лечение 28 пациентов обоего пола в возрасте 18-35 лет с сужением зубной дуги в переднем отделе на нижней челюсти до 7 мм. Все пациенты были разделены на 2 группы: 1-я группа – исправление формы нижней зубной дуги в переднем отделе без увеличения межклыкового расстояния; 2-я группа – исправление формы нижней и верхней зубных дуг в переднем отделе с увеличением межклыкового расстояния.
Результаты исследования и их обсуждение. Лечение только в нижнем зубном ряду с использованием элайнер-системы целесообразно проводить при дефиците места в переднем отделе зубной дуги не более 5 мм с применением межапроксимальной сепарации, расширения межклыкового расстояния и сошлифовывания суперконтактов после ортодонтического лечения либо сохранять ширину зубного ряда в области клыков на протяжении всего лечения.
Заключение. Успех ортодонтического лечения скученности передней группы зубов на нижней челюсти заключается в сохранении оптимальной индивидуальной ширины межклыкового расстояния и контроле данного параметра на протяжении всего лечения. Достижению этой цели способствует использование современной ортодонтической конструкции – элайнер-системы.

В настоящее время мезиальный прикус (МП) является одной из наиболее сложных аномалий по морфологическим, функциональным и эстетическим изменениям в зубочелюстно-лицевой области.
Цель исследования. Определить особенности диагностики и лечения МП согласно новому клиническому протоколу.
Результаты исследования и их обсуждение. Выделяют три степени выраженности МП, определяемые на основании соотношения передних и боковых зубов и параметров лучевого метода исследования (телерентгенографии головы в боковой проекции), а также соотношения и положения резцов верхней и нижней челюсти. Основой современной ортодонтии является грамотно составленный индивидуальный план лечения. Выбор адекватных методов диагностики, на основании которых осуществляется планирование лечения – чрезвычайно важный этап всей последующей работы. Главные принципы диагностики МП: выявление факторов, влияющих на его возникновение и развитие на зубоальвеолярном и (или) гнатическом уровне, определение степени выраженности, а также показаний к лечению, выбор метода лечения и тактики врача-специалиста; проведение дифференциальной диагностики МП; выявление взаимосвязи стоматологического и общего здоровья с наличием МП.
Заключение. Для лечения пациентов с МП разработан и клинически обоснован новый комплекс лечебно-диагностических мероприятий, позволяющий значительно улучшить функциональное и эстетическое состояние зубочелюстной системы обследуемого, а также снизить риск осложнений.

Published: December 2023

The COVID-19 morbidity code is used to determine the primary condition and secondary condition of a COVID-19 patient condition obtained during an episode of health care that is very important in hospital reporting, where from the morbidity data, the number of patients discharged (live and dead) and the formulation and health programs is obtained. At the same time, the COVID-19 death code is the main source for filling out patient death certificates. Death certificates will be used to report deaths, which are very useful for hospitals to evaluate service quality and the need for medical personnel and equipment to determine the morbidity and mortality code in COVID-19 patients at the Imelda Indonesian Workers General Hospital Medan in 2021. The method used in this research is observation and structured interviews. The results in this study are the number of patients from January to March 2021 who confirmed COVID-19, including 44 morbidity patients and 8 mortality patients, with suspected COVID-19 including 31 mortality patients. COVID-19 health workers, however, do not implement mortality coding for COVID-19 patients. The Imelda General Hospital of Indonesian Workers carries out the provision of a morbidity code for COVID-19 patients but does not carry out the provision of a mortality code for COVID-19 patients.
