Published: February 2025

Objective: The study aimed to characterize frozen-thawed sperm proteins and their correlation with sperm kinematics, acrosome integrity, and mitochondrial membrane potential (MMP) in Indonesian Toraya buffalo bulls.
Materials and Methods: Semen was obtained from six Toraya buffaloes classified as Saleko and Bonga 4–10 years old. The frozen semen was analyzed for sperm motility, sperm kinematics, viability, abnormalities, membrane integrity, intact acrosome, MMP, DNA integrity, and sperm protamine (PRM) deficiency. Sperm protein concentration (Prot. Con) was determined by the bicinchoninic acid, and protein molecular weight (MW) was determined using 1D sodium dodecyl sulfate-polyacrylamide gel electrophoresis with 4%–20% gradient gel and 6.5–240 kDa protein marker.
Results: The results of this study showed that the quality of frozen semen from Toraya buffalo bulls is in a good category and suitable for use in artificial insemination programs. The sperm quality differed significantly (p < 0.05) between individuals, immunofluorescence examination of intact acrosome, PRM deficiency, intact MMP, and intact DNA showed no significant difference (p < 0.05). Pearson correlations in this study showed that sperm Prot. Con has a significant correlation (p < 0.05) with acrosome integrity. The sperm protein band (Prot. Band) correlated significantly (p < 0.05) with sperm kinematic parameters and intact MMP. The average sperm Prot. Con of Toraya buffalo was 77.29 ± 39.26 μg/ml and 4–13 Prot. Bands with 6–240 kDa of MW were detected, with Prot. Bands of 16, 50, 70, and 115 kDa having higher intensity.
Conclusions: Frozen-thawed sperm protein is correlated with sperm kinematics, acrosome integrity, and MMP. The proteins were found to correlate with sperm quality and fertility in Toraya buffalo bulls.

Published: February 2025

Objective: This research aimed to evaluate in vitro ruminal fermentation, methane (CH4) emissions, and the relationship between the nutritional content and CH4 emissions of tropical feedstuffs to formulate low CH4-emitting feeds for ruminants.
Materials and Methods: Eighteen feedstuffs, including roughages (3 crop residues, 2 silages, 3 common grasses, and 4 leguminous fodder) and 6 concentrates, were evaluated using the Hohenheim Gas Test. Approximately 200 mg of feed were incubated with a rumen fluid-buffer solution for 72 h to test gas production (GP) and 120 mg for 24 h to determine the CH4 con-centration in the gas. Digestibility of organic matter (dOM) and metabolizable energy (ME) were calculated using GP data.
Results: Leguminous fodder contained the highest crude protein (CP) concentration (166–314 gm/kg dry matter (DM)), followed by common grasses (52–147 gm/kg DM) and silages (94–106 gm/kg DM), but the lowest concentration of detergent fiber fractions. Crushed wheat and maize had higher dOM and ME (87.8% and 90.9%, and 14.4 MJ/kg DM and 13.8 MJ/kg DM, respectively), and their CH4 concentration (% of GP) and CH4 emissions (L CH4/kg dOM) followed a similar trend as the other feedstuffs. The dOM and ME of German grass and Ipil-ipil were higher, whereas the CH4 concentration and CH4 emissions were lower compared to crop residues and other common grasses. The CH4 emissions originating from the feedstuffs were positively correlated with the concentration of neutral detergent fiber and GP and negatively correlated with CP.
Conclusion: Our result provides an opportunity to select feed ingredients with higher digestibility and concurrently less CH4 emissions in formulating diets for ruminants when using commonly available feed resources in many tropical countries. This may enhance animal productive performances while reducing the impact of animal production on the environment.

Published: February 2025

Objective: Fertilization rate of artificially inseminated cows using sexed and conventional semen in different seasons in South Papua.
Materials and Methods: Eighty crossbred cows aged 4–4.5 years with body condition score 3.8 were divided into groups A (summer = 40 cows) and B (rainy season = 40 cows). Each cow in each season was artificial insemination (AI) using sexed frozen semen and conventional semen. Frozen semen was evaluated for post-thawing motility (PTM), cell membrane integrity, and acrosome damage before synchronization using 5 ml PGF2α plus vitamin E. Using a visual gun, we identified cows in estrus on days 4–7 post-synchronization. Pregnancy of cows was detected using N5Vet ultrasound on days 35 and 55. The interaction between season, semen type, and fertilization level was analyzed using standard error and two-way ANOVA, assisted by SPSS 21 software.
Results: The wet season Temperature-Humidity Index (THI) level averaged 77.12 ± 1.19, and the summer season THI level averaged 82.67 ± 1.25. PTM quality averaged 60%–65%, viability 61%– 71%, sperm membrane integrity 62%–65%, and acrosome integrity 88%–91%. Conception rates (CR) value of rainy season (p < 0.05) with summer season. In addition, the services per conception (S/C) value in the rainy season (p > 0.05) is the same as in the summer. This study’s S/C and CR values were within normal limits, and the pregnancy rate reached 65%–86%. Pregnancy detection can be observed on day 35, and the fetal heartbeat is visible.
Conclusion: Post-AI fertilization using conventional semen was better in all seasons. The double dose of sexed semen can increase the fertilization rate in summer.

Objectives: Tuberculosis (TB) affects humans and animals regardless of species type, causing huge economic losses and deaths worldwide. However, the mechanisms and risk factors of zoonotic transmission are not well known in Pakistan. The current study aimed to identify the potential risk factors associated with TB in farmers and their animals, particularly exposure to infected animals in Lahore District, Pakistan.
Materials and Methods: The study consisted of two components utilizing the concept of One Health. In the first component, a retrospective case-control study of human subjects (cases = 25, control = 25) was conducted from December 2021 to July 2022. In the second component, a cross-sectional analysis of the cattle owned by selected participants (TB cases and healthy controls) was completed in the Lahore district. A single intradermal tuberculin skin test was used to determine TB infection in cattle.
Results: A total of 25 TB cases and 25 healthy controls were enrolled. Males in cases were found (OR = 0.01, 95% CI: 0.0002–0.29, p = 0.014) less likely to get TB, cases older than 35 years (OR = 1.13 (95% CI: 1.05–1.24, p = 0.004), unmarried cases (OR = 32.20, 95% CI: 2.92–819.03, p = 0.014), being a smoker (OR = 21.87, 95% CI: 2.80–395.82, p = 0.011), and keeping animals inside the home (OR = 9.92, 95% CI: 1.29–134.61, p = 0.047) were identified as significant predictors of TB in humans in the final multivariable logistic regression. Out of 175 tested animals, 3/65 animals belonging to the cases and 1/110 animals belonging to the controls were found positive. The animals belonging to the TB cases were (OR = 7.76, 95% CI; 0.79–76.02) more likely to have a positive Single Comparative Intradermal Tuberculin Test. The prevalence of bTB in animals belonging to the cases was 4.6% (95% CI, 1.26–12.58) compared to 0.9% (95% CI, 0.04–4.67) in animals of the control group.
Conclusion: This study identified potential risk factors that could contribute to the complex wave of TB transmission between humans and animals. Our findings could provide data to inform policy-making and intervention strategies to reduce TB’s burden in both populations. Embracing a holistic One Health perspective is imperative to effectively combat this shared health threat.
Assessment of PRRSV and PCV2 seroprevalence and antigen prevalence in minipigs at laboratory-animal production facilities
Authors: Lee Yoon , Kim Ji , Jo Woori , Kang Tae , Sung MinKyoung , Kim KilSoo , Park Na , Lee Gwang
Published: February 2025

Objective: Pigs are used in various biomedical research fields because of their anatomical and physiological similarities to humans. While farm pigs are raised outdoors for several months, minipigs are typically raised in indoor barrier facilities for several years. Although numerous studies have investigated the prevalence of major pathogens, including porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2), in farm pigs, similar studies targeting minipigs are lacking.
Materials and Methods: We imported 57 minipigs to our institution from three experimental animal production facilities and immediately assessed the serological and antigenic prevalence of PRRSV and PCV2.
Results: PRRSV and PCV2 had seroprevalences of 80.7% and 94.7%, respectively, with 0% antigen positivity rates for PRRSV types 1 and 2 and high-pathogenic PRRSV and PCV2. Two factors could account for the high seroprevalence rates: the majority of individuals may have been vaccinated despite official claims from the origin facilities or exposed to PRRSV and PCV2. Preventing microbial infections is crucial for obtaining accurate and reproducible results.
Conclusion: As the first investigation of microbial prevalence in minipigs, our findings indicate that minipigs raised in barrier facilities are not necessarily free from vaccines or infections. These results will significantly enhance the credibility of future biomedical research.

Published: February 2025

In recent years, there has been an increasing interest in smart city concepts in response to a growing demand for more sustainable and efficient urban spaces. In this paper, an in-depth exploration of load forecasting in an innovative city framework is carried out through the building of a software application with a graphical user interface (GUI) and prediction using long short-term memory (LSTM). To fulfill their role in enabling intelligent cities, accurate load forecasting is needed to enable energy management, reduce peak demand, and allow for well-informed decisions and energy distribution optimization. Specifically, in this work, we consider the application of LSTM to load forecasting systems within the context of a smart city. Since LSTM has a high capability in capturing complicated temporal structures, it is indeed an efficient approach to load forecasting, especially considering long-term dependencies. We focus on the strength of LSTM in comparison with the traditional statistical analysis and other machine learning techniques, most notably, LSTM’s ability to handle nonlinear and dynamic load behavior typical in innovative city energy systems. The GUI is the system's front end where the user enters the data, and at this point, we have the city officials, energy managers, and the community people and get their customized load forecast. The discussion of the outcomes of the experiment with the cross-platform GUI application and the improved LSTM forecasting model is given. Based on the evaluation of the model in terms of accuracy and performance, the research is done in an accepted manner to predict the complex load pattern in a smart city environment by proving the efficiency of the LSTM model. The effectiveness of different decisions in various cases is evaluated to consider the influence on decision-making processes and energy optimization; various cases demonstrate how the proposed GUI application is helpful in facilitating better management of energy. This research will, therefore, endeavor to create knowledge in the area of energy management to foster the development of effective intelligent cities.

Authors: Dania Rita , Bamgbade Adebisi , Isiaka Abdulmajid
Published: February 2025

Various traditional methods have been applied to detect cracks, these are prone to errors, require high human capital, high cost of equipment is involved and it is time consuming. In recent times, more sophisticated technologically based methods have been developed and used in the detection and analysis of cracks, inclusive of more advanced Artificial Intelligence (AI) technology. This study is aimed at evaluating the AI based Crack detection software for crack analysis. Cracks images were identified and captured using an android based smart phone from some selected residential buildings within Abuja and Benin-City. These crack images were analysed using Automated Building Exterior Crack Inspection Software (ABECIS). The software produced image segmentation and categorization. After the analysis, it consequently generated a report containing the confidence type, crack type, maximum confidence score, percentage of crack coverage and crack length. The cracks lengths for the selected images were also measured manually. The results indicate discrepancies between the crack lengths estimated by the software and those measured manually. The calculated Mean Absolute Error (MAE) is 0.84 while the Root Mean Square Error (RMSE) is 1.02. It was observed that greater error occurred in measuring the lengths of horizontal crack type. Despite these variations, ABECIS can significantly detect and measure the lengths of cracks to a reasonable degree of accuracy. The use of ABECIS saves time, cost, better analysis and portable record keeping for future review and maintainability of structural works for sustainable society. Therefore, it is recommended that the use of AI technology using ABECIS software can be advanced and promoted within the Nigerian construction industry for crack detection and analysis for effective maintainability and sustainability.

Las complejas relaciones de trabajo en España. Actores, organizaciones e instituciones en una inestabilidad funcional
Authors:   Universidad Pública de Navarra, Hernández de Frutos Teodoro
Published: February 2025

Cada año se produce una negociación institucional que afecta a millones de personas y familias en aspectos tan importantes como los salarios, las jornadas de trabajo, los despidos, las promociones, los traslados, la formación o las vacaciones. Son las relaciones de trabajo, vocablo este último, no nos olvidemos, que procede etimológicamente de la raíz latina tripalium o gran esfuerzo con que se roturaban las tierras con el arado romano. En este contexto, el libro tiene la firme intención de ahondar en algunos de los problemas fundamentales de lo que se considera el núcleo duro de dichas relaciones. El hilo principal que atraviesa la investigación de las relaciones laborales apunta a que el trabajo es más que una mercancía y un conjunto de recursos humanos. Del mismo modo, una suposición crítica que subyace en la obra es la existencia de un conflicto de intereses inherente entre empleados, empleadores y Estado que proviene de un choque de intereses económicos. El punto fuerte de esta obra es presentar una visión particular del mercado laboral español, fundamentalmente desde el ángulo de la negociación colectiva, las reformas laborales, la influencia de los mercados mundiales de la economía, que en su tiempo se denominó división internacional del trabajo, posteriormente globalización y en la actualidad cadenas de valor global; del uso y efectos de las tecnologías de la información y comunicación, que conducen las relaciones de trabajo hacia la transformación digital; del papel que desempeñan los sindicatos, en tanto que instituciones laborales y actores sociales; del rol de los empresarios como actores unitarios de negociación a partir de una evolución corporativista; de la formación continua, necesaria a lo largo de la vida laboral y de la actualización de los conocimientos de la fuerza de trabajo; de las habilidades y competencias necesarias para unos recursos humanos que se han quedado obsoletos y que se debaten entre la oferta y la demanda en lo que se conoce como desajuste; y, finalmente, del encaje de la inmigración y, más en concreto, de la situación de la población inmigrante que busca incorporarse al mercado laboral español.

In the evolution of humanity, with each new generation, children with a different level of consciousness come into this world. Due to the influence of historical events, modernization and the use of modern technologies, we are witnessing the flourishing of generational inequalities in which the educational methods of parents are differentiated. The changes of contemporary times are also markedly reflected in the diverse forms of family upbringing. In this paper, we present aspects of parental parenting, but also the impact of early childhood education and upbringing in institutional settings such as day nurseries or maternity centres. We will try to re/reconstruct the image of family education of contemporary parents, living in a globalized (European) society, which, moreover, is subject to transformational changes. Contemporary family education should actively and adequately participate in the upbringing and education of their children from an early age as an important indicator of the formation of the child's personality in the future. Therefore, we also focus on the importance of activating the relationship between the family and the maternity centers, education by means of nurseries, increasing the communication channels between them and finding out the level of psychological satisfaction of families with the educational services provided to the child. The aim of our study is to highlight and analyze the impact of parental education and the action of institutional facilities on the child's personality at an early age. Throughout the thesis, we have compiled scholarly sources, research findings from the Web of Science database, as well as exploratory analyses on the most widely used Slovak platforms and discussion forums in the period 2018 - 2023.

In this article, the authors analyze the matters related to AI-based and standard learning management systems (LMSs), investigate their role in education, and note their relevance in the organization of students’ training at universities. The authors consider LMSs as resources in the teaching-learning process during the coronavirus pandemic when universities have entirely moved to online education, highlighting LMSs’ essential and fundamental relevance. Moodle and Claroline were instruments and online platforms that provided additional support to learners in a distance-learning mode at that period. Delivering knowledge to learners, tailoring the content of the study, and making educational materials available to learners are much more effective with the LMS, in our view, not only in the online mode but also in a blended learning format. The research contributes to an in-depth understanding of how AI-based and standard LMSs such as Moodle, Claroline, and EdApp help teachers monitor the learning process remotely and help students feel supported in learning.
Consequences of Social Media on the Onset of Depression and Anxiety among Teachers from Junior Schools and Students from Teachers' Families and Relatives: A Comprehensive Cross-Section Survey
Authors: Alhomaidan Homaidan
Published: February 2025

Background:-Social media offering opportunities for connectivity, information sharing, and entertainment. However, alongside the benefits, there is a negative impact of social media use on mental health, particularly concerning depression and anxiety. This study determined the consequences of social media on the onset of depression and anxiety among teachers from junior schools and students from their families and relatives.
Methods:-This is a cross-sectional survey applied on the teachers (n=263) from junior schools and students (n=99) from their families and relatives from Qassim population of Saudi Arabia. A standardized instrument was applied to quantify the social media usage. Depression and anxiety levels were quantified using the Patient Health Questionnaire–9 (PHQ-9), the Generalized Anxiety Disorder Questionnaire–7 (GAD-7), respectively.
Results:-Among teachers, a majority displayed minimal depression (55.1%), with some showing mild (26.6%), moderate (10.3%), and severe depression (8.0%). Students also exhibited 56.6% minimal depression, followed by mild (16.2%), moderate (17.2%), and severe depression (10.1%). Regarding anxiety, teachers reported minimal (39.9%), mild (40.3%), moderate (12.5%), and severe (7.2%) anxiety. Similarly, students displayed anxiety levels as minimal (48.5%), mild (29.3%), moderate (10.1%), and severe (12.1%). The levels of depression and anxiety among studied teachers and students were not statistically comparable (p>0.05).
Conclusion:-This is the first study evaluating the effects of social media usage on the onset of depression and anxiety among teachers in junior schools and students from their families and relatives. A majority of both teachers and students experienced minimal levels of depression and anxiety due to their social media usage. Overall, these findings suggest that teachers from junior schools and students from their families in Qassim did not exhibit significant impacts of severe depression and anxiety from their social media use.

TiO2-based up-conversion materials dually doped with 0.2%Er3+ and 10/12%Yb3+ were synthesized using the sol-gel method. The samples were subjected to a calcination process at 500 °C for 2 hr. X-ray diffraction, scanning electron microscopy, UV-VIS diffuse reflectance spectroscopy, and X-Ray Photoelectron Spectroscopy were employed to investigate the effect of dopant concentration on the morphology, crystal structure, and up-conversion properties of the prepared samples. The results indicate that the prepared doped samples retained the anatase TiO2 crystalline phase and did not show any significant difference in morphology. Moreover, the band gap energy of TiO2 was found to decrease from the typical 3.2 eV (pristine TiO2) to 3.17 and 3.03 eV for the 0.2%Er3+ with 10 and 12%Yb3+ dopants, respectively, which can be attributed to the presence of Yb4f valence edge states. The Er4f state exhibited a transition absorption state in the near-infrared light range, indicating its crucial role in the potential up-conversion mechanism of the prepared doped samples.

The work is focused on the oxygen detection of colorimetric oxygen indicators by covering the indicator surface with different plastic wrap types. The layer of colorimetric detection was composed of titanium dioxides nanoparticles (TiO2), citric acid, methylene blue (MB) and polyvinyl alcohol (PVA). The precursor suspension was operated at 250 rpm by dry and wet milling process for 30 and 45 min. After that TiO2/MB composite was coated by the spin coating technique with a spin speed of 3000 rpm and 5 film layers on a glass substrate. The oxygen indicator with TiO2/MB composite film was presented in a blue film as indicated initial state. Then, plastic wraps with different types as polyvinylidene chloride (PVDC), polyvinyl chloride (PVC) and polyethylene (PE) were covered on the indicator surface to monitor its physical morphology, optical properties, and oxygen detection. Color changing in bleach and color state and oxygen detection of the indicators with the different plastic wraps were monitored by the snapshots in each hour for the cyan percentage analysis in the CMYK system. Meanwhile, the presence of bleach/color state in the indicators was confirmed by UV-Vis spectrophotometer focusing on the absorption range of MB dye to identify its state. The optimized covering plastic wrap on TiO2/MB colorimetric indicator was obtained by polyvinyl chloride that showed the identical indicator efficiency compared with the original indicator without the plastic wrap owing to good oxygen gas flow on its membrane. While the retardation of color changing in the indicator occurred by the polyethylene wrap on its surface due to the unique property of blocking oxygen gas flow.

The backgrounds of fraud and corruption in the Dutch Caribbean

The subjects fraud and corruption play an important role in the recent debate on the constitutional changes within the Netherlands Antilles and the ‘status aparte’ of Curaçao and Sint Maarten. The Netherlands and the various islands keep passing the blame on one another when it comes to fraud and corruption. It seems there is little willingness to look at the underlying causes or to express self-criticism. In this article an attempt is made to outline what is really going on in the field of fraud and corruption in the Caribbean part of the Kingdom. Several investigations on fraud and corruption committed by politicians in the past fifteen years will be addressed. Furthermore several socio-cultural, political and economic factors that play a role in causing fraud and corruption are being discussed. In this way the author hopes to contribute to a more constructive debate about the issue of fraud and corruption.

Radicals and ‘the powers that be’ in the Netherlands

This article presents a short historical introduction of the Dutch radical movement in the 1840s. What kind of people were these radical-democrats? Where did they come from? And what did they want? Moreover, this case study shows how government framed these radicals, and what actions were taken against them. It becomes clear, that from a historical perspective the continuity and similarities between the 1840s and the present are at least as remarkable as the differences.

Nuisance on the square; the architecture of public space

Public spaces are often seen by policy makers en researches as places that are essential for a social cohesive society. In daily life public spaces tend to be jungles where citizens rather stay away. Research in Rotterdam shows that much people indeed do not feel at home on ‘their’ squares. This situation can be improved by another view on the fysical construction of public spaces and squares in particular. Places where you can only play soccer are often confiscated by one group. For instance benches can make a place more attractive for different groups.
Absolute Positivism

Absolute Positivism

The paper argues that we miss the point and strength of Kelsen’s Pure Theory of Law if we take it to drive a middle way between reductionism and moralism. Rather conversely, the Pure Theory is a radical theory. It tries to overcome the opposition between reductionism and moralism by making clear that both opponents rest on the same ill-conceived convictions about legal validity. Both take it that the law cannot be normative by itself. In contrast, the Pure Theory tries to find a new approach to the understanding of law that takes seriously the constitutive functions of law. It tries to understand the validity of law as resting in law itself. As such it is an attempt to find a philosophically satisfactory formulation of what can be called absolute positivism.
Een analyse van het arrest ZZ (HvJ EU 4 juni 2013, zaak C-300/11) en de moeizame verhouding tussen geheime procesvoering en het recht op een eerlijk proces

Een analyse van het arrest ZZ (HvJ EU 4 juni 2013, zaak C-300/11) en de moeizame verhouding tussen geheime procesvoering en het recht op een eerlijk proces

In juni 2013 wees het Hof van Justitie een arrest naar aanleiding van een grotendeels geheime procedure op gronden van staatsveiligheid over de vraag hoe zo’n procedure zich verhoudt tot fundamentele beginselen van een eerlijke procesvoering, zoals onder meer terug te vinden in het Handvest van de grondrechten. De casus ziet op de toelating tot een lidstaat en ligt zodoende in de sfeer van het vreemdelingenrecht.

Het dilemma waar het Hof van Justitie voor stond, betreft een vaker gezien beslispunt waarvan de kern lijkt neer te komen op een ‘balancing act’, waarbij twee fundamentele beginselen worden afgewogen; dat van bescherming van de staatsveiligheid (of andere gegronde redenen voor een deels min of meer geheime procesvoering) tegen het recht op een eerlijke (en daarmee openbare) procedure. Zo bezien kan de uitspraak die hier besproken wordt wel eens bredere gevolgen hebben, ook voor onze rechtsorde. Dit artikel zoekt naar die mogelijke gevolgen.

Stefano Melloni: grenzen aan de nationale grondwettelijke grondrechtenbescherming bij uitvoering van een EAB

Het Hof van Justitie heeft zich in de zaak Melloni uitgesproken over de door de Spaanse constitutionele rechter opgeworpen vraag of de nationale rechter in het kader van een overleveringsprocedure aan de verzoekende staat – alvorens toestemming te verlenen de betrokken persoon over te leveren –, aanvullende eisen in de sfeer van de grondrechtenbescherming mag stellen die niet in het Kaderbesluit inzake het Europees aanhoudingsbevel staan vermeld. Deze bijdrage bespreekt de antwoorden van het Hof van Justitie op de door het Spaanse Constitutionele Hof gestelde prejudiciële vragen onder meer in het licht van de vaste rechtspraak van het Hof van Justitie over de voorrang van het recht van de Unie en duidt de betekenis van deze uitspraak met name in het licht van het bepaalde in artikel 53 van het Handvest.

This article aims to understand how Basic Education teachers perceive social inequality in education. Ten teachers from public schools participated in this qualitative, exploratory research. The information was obtained from an online questionnaire containing closed and open questions. The answers to two of the three open questions of the questionnaire were considered in this article. The Discursive Textual Analysis was chosen as an analytical method, based on the following a priori categories: i) situations experienced by teachers regarding social inequality in the school context; and ii) strategies developed by teachers to alleviate the implications of social inequality in education. The results have pointed out that teachers perceive such inequality through material deprivation and issues related to demotivation and family reality. As to the strategies used by teachers to mitigate this phenomenon, student welcoming actions and didactic-methodological adaptation are highlighted. The conclusions have shown the need for sensitive behavior on the part of teachers to identify the phenomenon and create alternatives to promote learning in an egalitarian manner.

For pupils, education is a lifelong process that ends when they develop into adults. Arabic language classes, which cover hearing, speaking, reading, and writing, are offered at religious education institutions ranging from elementary schools to universities. For pupils in class 2 of the PPTQ Al-Asy'ariyyah junior high school Tahfidz program, Kalibeber Wonosobo, the author restricts the issue of adopting and refining maharah kitabah learning utilizing the Imla' technique with the book Hayya Nata'allamu imla'. Unlike trials where the researcher is the primary instrument, this research uses it to investigate the circumstances of natural objects. Two methodologies were used in the research: experiments using both qualitative and quantitative methods.
