Authors: Dewantara Ananda Bayu , Dahda Said Salim , Dahda Said Salim
Published: June 2024

The manufacturing industry is a key pillar in global economic growth, yet the risk of failure remains a crucial challenge. PT XYZ, a plastic yarn manufacturer in Gresik, faces similar challenges despite achieving success. The production process is not yet optimal, with a defect rate exceeding the standard limit. This research utilizes the FMEA and Kaizen approaches to identify priority failure modes and propose improvements. Analysis indicates that yarn spot defects are the top priority for correction, attributed to insufficient pump pressure. Proposed improvements based on the Risk Priority Number include installing pressure control devices, implementing preventive maintenance, and providing support facilities for operators. Therefore, these improvements are expected to enhance the efficiency and the quality of the plastic yarn production process at PT XYZ Gresik. Keywords: Diagram Pareto, Diagram Fish Bone, FMEA, Kaizen

Published: June 2024

One of the most pressing social problems in the world is poverty. One of the efforts to overcome poverty in Indonesia is to group provinces in Indonesia based on indicators of poor households, so that the government can develop poverty reduction strategies according to provincial groups. Cluster analysis is a process of grouping numbers observations based on certain patterns or similarities from these observations. Cluster analysis is divided into two, namely hierarchical and non-hierarchical cluster analysis. Non-hierarchical cluster analysis that can be used is the K-Modes method. K-modes analysis is clustering which is used to group categorical type data. Based on the results of cluster analysis using the K-Modes method, it was found that cluster 1 is a cluster that meets 9 indicators of poor households so that provinces in cluster 1 need to be prioritized in reducing poverty. The Davies Bouildin Index (DBI) is used to see how good the cluster results are used in the K-modes algorithm. By using the DBI, the best number of clusters was obtained as 2 clusters with a DBI value of 1.94063.

The conflict between Israel and Palestine is the Middle East's longest-running conflict since 1917 and is still ongoing today. This is one of the international conflicts that involves many Arab countries and Western countries in the dispute. The conflict between Israel and Palestine has caused countries in the world to be divided into two camps, namely the pro Palestinian independence camp and the contra camp. The impact of this conflict also creates polarization among Indonesians and forms diverse public opinions on the social media application X. The purpose of this research is to find out how the classification of sentiment of X application users affects the conflict between Israel and Palestine. An analysis that is utilized to convert text-based public opinion data into information is sentiment analysis. The chosen algorithm to separate data classes is the Support Vector Machines algorithm, which can classify data by determining the best hyperplane to provide a separator between opinions that are pro Israel or pro Palestine. After the preprocessing stage, 1000 tweets data were obtained with 800 training data and 200 testing data. The accuracy rate is 93%, precision is 92.93%, recall is 100%, and f-measure is 96.33%. From the results of testing 200 data points, there were 198 pro Palestine opinions and 2 pro Israel opinions, so that it might be said that more individuals favor or support Palestinian independence in the conflict that occurred between Israel and Palestine.

Optimizing Legal Protection: Addressing the Disparity of Sanctions Regarding Personal Names in Birth Certificates as Population Documents
Authors: Maskur Ali , Shabir Muslich , Hapsin Abu , Rismana Daud , Purwanto Joko
Published: June 2024

This article discusses the issue of disparity in sanctions arising from the issuance of the Regulation of the Minister of Home Affairs of the Republic of Indonesia on Name Registration in Population Documents. A case in Tuban highlights a child who was unable to obtain a birth certificate because the name was too long to be entered into the Population and Civil Registration Office system. The regulation imposes restrictions on naming children, requiring a minimum of two words and no more than sixty characters. Non-compliance with this regulation can result in the non-issuance of a birth certificate, potentially rendering the child stateless. This situation contradicts UDHR Article 15, ICCPR Article 24, CRC Articles 7-8, and the 1945 Constitution Article 26 (1) on citizenship. The purpose of this study is to highlight the imbalance between regulatory rules and sanctions, demonstrating how lower-level regulations can violate higher-level rules. This research employs a qualitative, literature-based, and normative-doctrinal approach. Secondary data sources include Permendagri No. 73/2022, the Population Administration Law, the 1945 Constitution, and international regulations related to population and citizenship. The findings indicate that birth certificates reflect the state's responsibility to provide citizens with rights, including the right to identity. However, the sanction of not issuing a birth certificate due to regulatory non-compliance creates a disproportionate disparity in naming rights. Therefore, policy revision is necessary to optimize legal protection, making the system more equitable and in line with legal norms.

The solution provided by information and communication technology to the educational challenges that the education system has faced as a result of the pandemic situation due to the COVID-19 virus has been generally agreed upon and accepted on a planetary scale by the entire academic community. For an important period of time (approximately 1.5 years), the didactic activity took place mainly asynchronously. The implications of this fact on academic performances, the quality of the didactic act, and the well-being of students are addressed in many studies in order to find out answers considered as predictions of future instructive-educational actions. The present study is also included in the same dimension. The results recorded or highlighted the fact that learning in the online system presents both advantages (maximizing the use of time due to the elimination of losses due to travel, domestic comfort, and the exclusive decision to interact) and disadvantages (deficient feedback, investment of intellectual effort to obtain a positive relational agreement); motivation was slightly higher, assessment anxiety and learning efficiency were lower, while comfort and satisfaction with learning did not register significant changes. The preference that students emphasized for the way the didactic activity should be carried out aims at an alternation of synchronous and asynchronous activities in the mixed system, doubled by learning in the online system.

Embodied cognition activities involve active interactions that train the motor system, the perceptual system and physical interactions with the proximal environment. In the language education of young preschoolers, these types of activities train young preschoolers in the process of learning new words, their comprehension and correct pronunciation. The article presents the influence exerted by the „Integrated exploitation of sensory-motor stimuli” educational program with an emphasis on capitalizing on embodied cognition activities, in the early language education approaches of small preschoolers. Early language education through this type of activity proves effective because it encourages children to make connections between words and concepts using tactile, visual and motor experiences. This approach helps to develop strong connections between words and their meanings. The methods used were the observation of the language behavior of the preschooler and the psychopedagogical experiment method, and the applied research tools, the observation grid of the language behavior of the preschooler and the educational program „Integrated exploitation of sensory-motor stimuli”. The study involved 98 small preschoolers, aged between 3 and 4 years, from 3 state preschool education units, from the urban and rural areas of Hunedoara County. The three educational units involved in the research are: „Mircea Sântimbreanu” Secondary School Brad, „Flore de Colț” Extended Program Kindergarten Brad and „Crișcior Extended Program Kindergarten”.
Nieznany twórca słynnej polskiej pieśni – rzecz o Antonim Wincentym Rutkowskim
Authors: Makal–Żmuda Katarzyna
Published: June 2024

Tematyka niniejszego artykułu ukazuje obecny stan badań Autorki nad spuścizną kompozytorską Antoniego Wincentego Rutkowskiego, wybitnego polskiego kompozytora, pianisty i pedagoga, profesora Warszawskiego Instytutu Muzycznego, żyjącego w drugiej połowie XIX wieku. Na ich podstawie Autorka dowodzi o odnalezieniu wydanej we Lwowie pieśni, zatytułowanej „Modlitwa uciemiężonych”, skomponowanej przez Rutkowskiego do słów Kornela Ujejskiego, jako utworu tożsamego ze słynną pieśnią, powszechnie znaną pod nazwą „Z dawna Polski Tyś Królową”. Niniejsze odkrycie obala istniejący współcześnie pogląd o anonimowym autorstwie tego utworu, uznanego za jedną z najważniejszych polskich pieśni maryjnych i patriotycznych. Nadrzędnym celem niniejszej pracy jest udokumentowanie powyższego odkrycia, a także przekazanie istotnej wiedzy, dotyczącej życia i twórczości, a także dostępności dzieł kompozytora, który pomimo niepospolitego talentu, jest jednym z mniej znanych polskich twórców drugiej połowy XIX wieku. Źródłem zachowanych najcenniejszych informacji o Rutkowskim, które stały się przyczyną zainteresowania Autorki niniejszym tematem, jest przekaz pozostawiony przez wybitnego polskiego pianistę i kompozytora, a zarazem polityka i męża stanu – Ignacego Jana Paderewskiego. Esej Jego autorstwa, pochodzący z 1886 roku, zatytułowany „Wspomnienie pośmiertne” rzuca jasne światło na osobowość i sylwetkę twórczą Rutkowskiego, a także stanowi podwalinę charakterystyki dzieł, których Paderewski był wielokrotnym wykonawcą i słuchaczem. Niestety w wyniku przedwczesnej śmierci Rutkowskiego, a także ówczesnej trudnej sytuacji politycznej Polski, będącej krajem pozbawionym suwerenności ze wszystkimi jej następstwami, dorobek twórczy artysty stopniowo ulegał zapomnieniu. Kompozycje, które szczęśliwie przetrwały kolejne zawieruchy wojenne, pozostawały w słabej jakości manuskryptach lub pierwszych, dziewiętnastowiecznych wydaniach i były rozproszone, w posiadaniu polskich i zagranicznych bibliotek. Z powodu utrudnionej dostępności, z czasem przestały być wykonywane. W wyniku prac badawczych podjętych przez Autorkę oraz współpracy redakcyjnej z wydawnictwem Eufonium, obecnie zostały wydane trzy publikacje, będące zbiorami utworów Rutkowskiego, zaś pozostałe są w przygotowaniu. Niebawem ukaże się także płyta zawierająca wszystkie dzieła fortepianowe i kameralne kompozytora, przygotowywana przez wydawnictwo Chopin University Press. Autorka żywi nadzieję, że przedstawione w niniejszym artykule efekty badań staną się asumptem popularyzacji i zainteresowania twórczością Antoniego Wincentego Rutkowskiego – spadkobiercy najwybitniejszych twórców polskiego romantyzmu.

Badaniom pilotażowym zostały poddane kobiety – 50 uczestników zajęć fitness, treningów personalnych, którzy pragną poprawić swoje zdrowie i sylwetkę poprzez aktywność fizyczną. Fitness dla większości z nich jest sposobem na spędzanie czasu wolnego oraz pasją, która daje im możliwość własnego rozwoju fizycznego i psychicznego, co bezwzględnie wiąże się z emocjami, które mogą mieć wpływ stresogenny. Pomimo dużego wysiłku fizycznego, kobiety lubią spędzać czas aktywnie, daje im to dużą satysfakcję. Dostrzegają one wiele korzyści z uczestnictwa w zajęciach fitness oraz posiadają swoje motywy do podejmowania ich. Duża ilość form fitness daje możliwość wyboru zajęć dostosowanych do potrzeb uczestników. Kobiety mocniej zmotywowane, pewniej osiągną korzyści dla swojego zdrowia, samopoczucia oraz sprawności fizycznej. Fitness jest ciekawą forma rekreacji ruchowej, dlatego kobiety często wybierają ten rodzaj aktywności. Fitness to współczesna forma rekreacji ruchowej wybierana przez kobiety w różnym wieku. Fitness jest także dla kobiet w wieku średnim atrakcyjną i potrzebną formą aktywności fizycznej oraz stanowi ważny element w ich życiu, zajęcia fitness kształtują rozwój fizyczny i psychiczny kobiet oraz dają im wiele korzyści, wpływają pozytywnie na jakość życia.

Допінг та його вплив на спортивну конкурентоспроможність
Authors: Мельніков Андрій Вікторович , Шинкарук Віктор Олександрович , Жиров Дмитро Віталійович
Published: June 2024

У сучасному світі спорту використання допінгу стає все більш актуальною темою, що породжує широку дискусію та негативне ставлення. Вирішення цієї проблеми передбачає співпрацю між спортивними організаціями, правоохоронними органами, науковою спільнотою та іншими зацікавленими сторонами для розробки ефективних стратегій контролю, профілактики й відшкодування в разі порушень. Допінг у спорті є поширеною проблемою не лише серед елітних спортсменів, але й у рекреаційних видах спорту. Стаття базується на аналізі наукової та методичної літератури. Хоча в науковій літературі велика увага приділяється виявленню допінгу, мало обговорюється згубний вплив допінгу на конкурентоспроможність спортсменів. Історично проблема допінгу почалася в XIX столітті, але вона значно поширилася після Другої світової війни внаслідок системних командних допінгових програм. Також описані санкції та наслідки для спортсменів, які порушують антидопінгові правила. У статті розглядається і взаємозв’язок між фізичною активністю, здоров’ям і вжи- ванням заборонених препаратів для покращення результатів у спорті. Існує роз- ділення допінгу на різні категорії, такі як речовини та методи, заборонені завжди, та ті, що заборонені лише під час змагань. Поширеність допінгу визначається через опитування або тестування учасників, проте є проблеми, пов’язані з відмінностями у визначеннях допінгу та приймання «заборонених» речовин із соціальних міркувань, а також з обмеженнями збору зразків. Результати досліджень показують значну поширеність вживання допінгу серед спортсменів, з якою потрібно ефективно боротися для збереження чесності й етики в спорті. Допінгові скандали впливають на інтегрітет спорту та викликають сумніви в спортивній справедливості. Відкриття допінг-проблем відомих спортсменів часто шокує світову громадськість і порушує заслужений авторитет спортивних зірок. Мета статті – дослідження впливу допінгу на спортивну конкурентоспроможність. Проте вплив допінгу на спортивну конкурентоспроможність не обмежується лише негативними наслідками. Відчутний натиск на досягнення виняткових результатів і боротьба за перемогу часто приводять спортсменів до вибору нетрадиційних засобів підвищення продуктивності. Це надає широкі можливості для аналізу впливу допінгу на спортивні досягнення та перспективи боротьби із цим явищем.

Published: June 2024

Tras años de recopilar materiales del autor, gracias al afán archivístico de su familia, la Editorial Renacimiento imprime Los años enterrados dentro de su colección “Biblioteca del Exilio”. Aunque ubicada en el nicho de la literatura del exilio, la obra escrita por Ricardo Bastid reverbera tanto en expertos como en estudiantes de formación, así como en cualquier lector deseoso de desenterrar una figura destacable de la posguerra y el exilio tardío. Como afirma Francisco Agramunt en Arte y represión en la Guerra Civil española, Ricardo Bastid “fue un bello ejemplo de inconformismo político y de lealtad a unos principios éticos, ideológicos y democráticos asumidos en su juventud (…) uno de esos intelectuales puros y comprometidos”. A través de un compromiso reflejado en su participación voluntaria en la Guerra Civil, Los años enterrados, obra presentada al Premio Nadal en 1959, contiene en su historia la vida de un escritor que, tras experimentar el exilio en Buenos Aires, donde encontró trágicamente la muerte, ofrece un nuevo panorama de la memoria española.

Degenerative diseases arise when age increases due to the weakening of the body's physiological condition. The purpose of this study was to measure glucose, uric acid, and cholesterol levels in residents of Segunung Village to improve lifestyles and quality of life. As many as 110 residents of Segunung Village were used as subjects in this cross-sectional study. Glucose, uric acid, and cholesterol levels were measured using Point of Care Testing (POCT). A cut-off value of <200 was used to define high cholesterol levels. Only cholesterol levels showed an increase when compared with reference values, while glucose and uric acid levels were normal. Interestingly glucose was significantly correlated with age (r=0.309, p=0.001). The approach using POCT describes the overall condition of Segunung villagers and can be used as a basis for glucose, uric acid, and cholesterol screening tests.

COVID-19 antigen is an alternative test for detecting SARS-CoV-2 infection. Viral load represented by the Cycle Threshold (CT) in the Real-Time Reverse Transcriptase Polymerase Chain Reaction (rRT-PCR) affects the diagnostic performance of the test. Higher CT values result in reduced sensitivity of the SARS-CoV-2 antigen. The main objective of this study was to determine the highest CT value in rRT-PCR that still yielded reactive results in the COVID-19 antigen test. This cross-sectional study was conducted at the Fever Outpatient Clinic in Dr. Cipto Mangunkusumo Hospital from July 2020 to June 2021. Two hundred and thirty-five naso-oropharyngeal swabs were taken from patients with confirmed and suspected COVID-19 diagnoses. About 24.7% of subjects were tested positive. The median highest CT value giving reactive COVID-19 antigen results was 28.22 (13.33-39.16), while the median CT value for non-reactive antigen results was 34.45 (26.08-39.65). At a CT value < 40, the COVID-19 antigen test demonstrated 63.8% sensitivity, 99.4% specificity, 89.3% Negative Predictive Value (NPV), and 97.4% Positive Predictive Value (PPV). At the CT value < 25, the test showed 92.3% sensitivity, 99.4% specificity, 99.4% NPV, 92.3% PPV, 163.4 LR+, and 0.1 LR-. The identified cut-off point for the CT value was 29.82, with a sensitivity of 64.9% and specificity of 81%. In conclusion, COVID-19 antigen is a valuable test for screening patients with symptoms of SARS-CoV-2 infection. Understanding the influence of cycle threshold can enhance the interpretation and reliability of the antigen test.

Authors: Sidhartha Elizabeth , Ronald Thoeng
Published: June 2024

The Urine Albumin/Creatinine Ratio (uACR) is one of the earliest markers of glomerular disorders. A comparative study of semi-quantitative urine uACR and quantitative uACR tests was carried out using Meditape UC-11A test strips on the Sysmex UC-3500 (automated urinalysis instrument) and Roche Cobas 501, respectively. A total of 213 retrospective data of urine chemistry tests were collected. Semi-quantitative urine albumin, creatinine, and uACR data were obtained using Meditape UC-11A strips on Sysmex UC-3500, whereas quantitative data were obtained using Roche Cobas c501. A weighted Cohen's Kappa agreement, sensitivity, specificity, PPV, NPV, and accuracy were analyzed using data from both instruments. The Kappa values for urine albumin, creatinine,  and uACR between the semi-quantitative and quantitative methods were 0.83 (CI 0.771– 0.880), 0.535 (CI 0.417–0.652), and 0.691 (CI 0.606–0.775), respectively. The sensitivity, specificity, PPV, NPV, and accuracy of semi-quantitative methods were 90%, 73.3%, 75%, 89.2%, and 81.2%, respectively. The semi-quantitative uACR test on the UC-3500 showed excellent performance and could be used as a screening test for early detection of impaired kidney function.

Published: June 2024

The aim of this article is to investigate the impediments to creativity perceived by managers, the levels of creativity, its indicators, and personal characteristics conducive to creativity, as well as to elucidate the correlations among them. An experimental study was conducted involving 300 participants. Methods employed include surveying, testing, and mathematical statistical analysis. As the level of creativity increases, participants tend to assess their opportunities more favorably. The expression of creativity depends on the interconnection among the barriers to creativity, indicators of creativity, and personal qualities of creativity. A high level of creativity is manifested when there are fewer barriers and personal qualities such as Imagination and a propensity for Risk-taking. Conversely, the level of expression of creativity is low when there is an interconnection between Creativity and Complexity, Imagination, and creativity barriers such as lack of confidence and conformity to majority opinion.
Academic Procrastination and School Satisfaction: Mediating Role of Academic Stress
Authors: Akbaba Mehmet Fatih
Published: June 2024

This investigation sought to explore the mediating role of academic stress in the linkage between academic procrastination and school satisfaction among Turkish adolescents (N = 362; Mage = 15.22, SD = 1.22). It was found that adolescents' academic procrastination had a negative correlation with school satisfaction, and their levels of academic stress were positively related to satisfaction with school. Utilizing structural equation modeling, the analysis revealed that academic stress served as a partial mediator in the relationship between academic procrastination and school satisfaction. Consequently, the indirect influence of academic procrastination on school satisfaction, mediated through academic stress, was statistically significant.
Effect of flow orientation in experimental studies on FC-770 boiling heat transfer in asymmetrically heated minichannels
Authors: Piasecka Magdalena , Strąk Kinga
Published: June 2024

The article presents experimental results of boiling heat transfer during FC-770 flow in a group of five minichannels with a common heated wall. The flow orientation was changed from 0º to 180º, with a 15° increment. During the experiments, the temperature of its outer heated wall surface was measured by an infrared camera. At the same time, flow patterns were captured through the glass plate opposite the heated wall using a high-speed camera. The purpose of the calculations was to determine local heat transfer coefficients on the contact surface between the working fluid and the heated surface in the central minichannel, using a simplified 1D calculation method. The results in the form of dependences of the temperature of the heated wall and the heat transfer coefficient as a function of the distance from the channel inlet for various flow orientations were analysed. Furthermore, typical boiling curves and two-phase flow patterns were presented. The mean relative error of the heat transfer coefficient was determined for various flow orientation. The dependence of the void fraction as a function of heat flux was illustrated for various angles of minichannel inclination to the horizontal plane. It was observed that the void fraction increased with heat flux and with increasing angle of inclination of the minichannel to the horizontal plane.
Experimental and statistical determination of thermal characteristics of the special design minichannel heat exchanger

Published: June 2024

The paper presents the results of experimental investigation and the new statistical method for the determination of pre-liminary thermal characteristics of a prototype compact minichannel heat exchanger with laminar flows and significant heat transfer in the manifolds. The exemplary heat exchanger consists of 9 straight, parallel, square-shaped channels and two rectangular-shaped manifolds milled on both sides of the single aluminium plate. The design of the investigated heat exchanger is quite particular, as the heat transfer area of both pairs of manifolds provides almost 1/3 of the total heat transfer area. In the new statistical method presented in this paper, the manifolds’ and channels’ heat flows are considered separately. The heat exchanger’s thermal characteristic was obtained statistically on the basis of the experimental results and is presented in the form of the overall heat transfer rate. The developed thermal characteristic model accounts for two effects, among many others, which may affect heat transfer in the exchanger, i.e. the heat loss to the ambient and the significant heat transfer in the manifolds. It is proved that the heat transfer to the surroundings was negligible due to the suitable thermal insulation. In order to demonstrate that the heat transfer in the manifolds is significant, two calculation variants are presented. The relative differences (residuals) between the experimental and statistically corrected heat transfer rates and the coefficient of determination R2 are determined in both variants. In the first variant the heat transfer in the manifold pairs is neglected and in the second model it is included. It was observed that the lack of consideration of the heat transfer in the manifold pairs provides drastic dispersion between the experimental and statistical results. In turn, in the second model, where the manifolds are accounted for, a significant enhancement in the consistency of the results is noticed. The relative residuals are much lower, and the corresponding coefficient R2 is improved from R2 = 0.8827 in the first variant to R2 = 0.9335 in the second one, respectively.

Published: June 2024

This paper presents the results of experimental investigations of the basic thermal property – the specific heat capacity of selected heterogeneous materials – graphene oxide rubber composites. The value of specific heat capacity was measured with a PerkinElmer DSC 8000 differential scanning calorimeter using modulated temperature mode of operation. The heterogeneous material under investigation was the graphene oxide/rubber composite, which is used in the production of roller bearing seals. Two types of rubber have been used as the basic matrix of composites: the hydrogenated acrylonitrile butadiene rubber and the fluoroelastomer. Graphene oxide reduced with sodium hypophosphite was applied as a compo-site filler. The main goals of the work was to expand the database of thermophysical properties of materials and to inves-tigate the influence of material heterogeneity on the results of specific heat capacity measurements obtained with small-sized test samples.
Determination of the heat capacity of a water-ice reservoir as a lower heat source for heat pump - Numerical analysis
Authors: Tarnawskia Piotr
Published: June 2024

The paper presents the design of a heat exchanger immersed in a water-ice reservoir and the determination of its heat capacity as a lower heat source for the heat pump. This is an innovative solution, the first project on this scale in Poland. Heat absorption from the water-ice tank took place in three stages: from water at a temperature range of 20oC to 0oC, from the water-ice phase change at 0oC, and from ice at a temperature range of 0oC to 10oC. The CFD (Computational Fluid Dynamics) analysis of a heat exchanger performance was performed. It required simulation of water natural convection, water-ice phase change, and heat transfer from the ground. The heat flux absorbed in the designed exchanger was calculated based on the current glycol temperature and the implemented COP (Coefficient of Performance) characteristic of the heat pump. This was done via the user-defined function (UDF) available in Ansys FLUENT. The compiled internal software subroutine was defined based on the DEFINE_ADJUST macro. Moreover, the thermal resistance of ice forming on the pipes was included. The numerical analysis indicated that 66097 kWh of heat would be absorbed from the reservoir in 500 hours of exploitation. The volume fraction of water at the end of the simulation was equal to 26.7% and the volume fraction of ice was equal to 73.3%. The CFD simulation confirmed the heat capacity value of the water-ice storage tank which fulfilled the design requirements.
