Authors: Fajar Dinar Maftukh , Sholehuddin Muhammad , Habibbulloh Muhammad
Published: February 2025

One device that is commonly used to demonstrate electrostatic phenomena is the Van de Graaff generator. However, this device is found to be expensive, relatively large, hard to move, and not available in many school laboratories. This paper aims to describe the experiment of creating a simple portable handheld Van de Graaff generator produced by employing second and easily available materials in the local market. This device collects charges from two materials that rub against each other. The combination of chosen materials listed in the triboelectric series determines the type of charge on the generator. This research used the experimental method by continuously testing the prototype to find the best result using the following steps: start, theory, design, material selection and assembly, testing, completion, and finish. A charge conduction experiment and a charge type test through a simple Coulomb experiment or an electrostatic polarity detector successfully tested the final product. The results showed that the device could effectively demonstrate basic electrostatic phenomena, making it a practical and affordable alternative for classroom demonstration.
Developing a Multi-Representation-Based Physics Mobile Learning to Enhance Critical Thinking and Creative Problem-Solving Skills: A Storyboard
Authors: Zakiyah Sri , Suwarma Irma Rahma , Rusdiana Dadi
Published: February 2025

This investigation aims to develop an M-Learning-based learning design for high school pupils in the context of a soundwave lesson specifically to increase critical thinking (CT) skills and creative problem-solving (CPS) ability. This learning media design is created through the ADDIE process, comprising five stages: analysis, design, development, implementation, and evaluation. In this paper, we will elaborate on the analysis and design phases. The analysis phase involves a preliminary examination of the teaching materials necessary for mobile learning. The design stage also involves selecting the proposed prototype's overarching design and creating storyboards. Three of the five subchapters that have been developed have the potential to employ CPS features, while CT features are feasible to integrate into all chapters. These findings suggest that physics mobile learning can be designed to incorporate CT and CPS specifically in the lesson on soundwave.

Authors: Habibah Habibah , Syam Muliati , Komariyah Laili
Published: February 2025

One problem in the school environment is the lack of information to improve attitudes that reflect environmental concerns. There is a need for methods to improve student's learning outcomes and pro-environmental behavior. This research aims to determine whether there is an increase in applying pro-environmental teaching materials to the educational objectives and behavior of high school students in Samarinda. This study used a pretest-posttest design with a single group and a quantitative methodology. Thirty-four people were selected for the sample using the purposive sampling technique. The data-gathering method includes questionnaires about environmental care behavior on global warming material, essays, and multiple-choice tests. The research was implemented over five class sessions using pro-environmental teaching materials developed by Anwar (2023), which included group discussions and interactive activities to raise awareness of global warming. Students' progress was assessed through regular observations and post-discussion evaluations. According to the study, student learning outcomes improved from 45.48 on the pretest to 77.79 on the post-test, resulting in a 0.57 rise in N-Gain and a moderate classification. Additionally, environmental care behavior enhanced from 44.85% on the pretest to 88.23% on the post-test, earning it a moderate classification with a 0.39 rise in N-Gain. As a result, the high school students in Samarinda demonstrated a considerable improvement in both behavior and learning outcomes when pro-environmental instructional materials were used. The study results can be used to improve the curriculum's ability to promote environmentally conscious behavior and awareness through development and adaptation. In summary, using pro-environmental instructional materials greatly enhances students' pro-environmental behavior and learning results in the context of global warming content.

Authors: Kurniasih Lutfi , Samsudin Achmad , Aminudin Ahmad
Published: February 2025

This study aimed to develop Physics Learning Media assisted by Rebuttal Texts (PhyLeM-ReT), integrated with the Predict, Observe, Explain, Apply, and Write (POEAW) model for work and energy material. The development research design employed in this study was ADDIE (Analysis, Design, Development, Implementation, and Evaluation). The participants were 30 tenth-grade students from a private high school in Bandung. A student response questionnaire to the media was implemented, which comprised 19 statements (10 positive and nine negative) and was evaluated using a Likert scale. This study implemented Rasch analysis. The result showed that 25 students agreed with the positive statements and disagreed with the negative statements related to interest in learning physics, the use of media, enthusiasm for learning, and usefulness in understanding concepts. Thus, PhyLeM-ReT integrated with the POEAW model facilitates students' comprehension of energy and work material. The developed media can also serve as an alternative for teachers in teaching, specifically enhancing and transforming students' conceptions. This research is crucial in an era where misconceptions regarding physics persist, as it aims to offer effective alternative learning media that can address these obstacles. Additionally, this research presents opportunities for further development in integrating comparable methods into other subject areas of physics that necessitate a profound conceptual approach.

Future research is expected to emphasize the SPS indicators and better organize students to play a more active role in learning activities.
Technology Focus: Formation Evaluation (February 2025)
Authors: Wang Haijing
Published: February 2025

Formation evaluation combines well logs, core and fluid analysis, and interpretation techniques to characterize subsurface formations. It spans the entire life cycle of a field, from exploration to abandonment, and bridges all subsurface disciplines. As reservoir complexity and energy-transition demands grow, the industry is developing new logging technologies, integrating multidisciplinary functions, and conducting new experiments to address new challenges. This Technology Focus highlights three papers from conventional, unconventional, and carbon-storage projects.

New logging technologies are leading the way for well placement in conventional reservoirs. Paper SPE 222993 discusses the use of modern ultradeep azimuthal resistivity (UDAR) tools for horizontal well placement in low-resistivity, low-contrast, and thinly laminated clastic reservoirs. This work combines prewell modeling, a new near-bit UDAR transmitter design, and an optimized inversion algorithm to enable real-time decision-making and maximize reservoir exposure.

Pore pressure in unconventional reservoirs significantly affects well performance. Paper URTeC 4042140 examines regional pore-pressure variations in the Permian Basin’s producing strata, highlighting vertical and lateral heterogeneities on a basinwide scale. The Midland Basin Spraberry is near or below the hydrostatic pressure gradient, whereas the Wolfcamp Formation is mostly overpressured. These observations could be of great importance for estimating recoverable resources.

In carbon-storage projects, the potential loss of CO2 injectivity in saline aquifers from brine dryout and salt accumulation near the wellbore remains uncertain. Paper SPE 219993 designs laboratory and digital analyses of sandstone cores to calibrate petrophysical and dynamical properties upon salt precipitation and flow reduction. The cores undergo repeated brine infiltration and drying cycles, followed by high-resolution 3D imaging and pore-scale simulation to visualize and quantify the effect of salt accumulation on permeability. The calibrated results can be integrated into reservoir models to evaluate injectivity impairment caused by salt clogging.

Subsurface Data Reveal Pore-Pressure Variations in Shale Basins
Authors: Carpenter Chris
Published: February 2025

_

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper URTeC 4042140, “Regional Pore-Pressure Variations of the Wolfcamp, Dean, Spraberry, and Bone Spring Formations of the Midland and Delaware Basins in the USA,” by Shuvajit Bhattacharya, Ray Eastwood, and Katie Smye, The University of Texas at Austin, et al. The paper has not been peer reviewed.

_

The authors study regional pore-pressure variations in the Leonardian and Wolfcampian producing strata (Wolfcamp, Bone Spring, Avalon, Dean, and Spraberry) in the Midland and Delaware Basins of West Texas and southeast New Mexico. Pore pressure is analyzed with a variety of subsurface data, including sonic logs and completions data. Results show that pore pressure is consistently higher in the Wolfcamp Formation (especially Wolfcamp B, C, and D) and Delaware Basin Bone Spring S3 than the Spraberry Formation in the Midland Basin.

Introduction

Over the years, several studies have been conducted on pore pressure in different shale reservoirs in the Permian Basin. A few recent studies used 3D seismic data to estimate and map pore pressure in the Permian. However, few published studies exist on basinwide variations of pore pressure in producing shale formations in the Permian. Uncertainty persists as to why pore pressure is different in age-equivalent formations in the Delaware and Midland Basins.

The authors study regional pore-pressure variation in selected Leonardian and Wolfcampian shale formations at the basin scale, integrating well logs, completions, and reservoir data. The challenges and opportunities presented by different kinds of subsurface data in estimating pore pressure are discussed. Pore-pressure-gradient maps reveal vertical and lateral changes in pore pressure in the Permian Basin.

Methods

Pore pressure of the Wolfcamp, Dean, Spraberry, Bone Spring, and Avalon Formations in the Midland and Delaware Basins was studied with a combination of sonic logs, instantaneous shut-in pressure (ISIP), diagnostic fluid injection tests (DFIT), mud weight, and other approaches.

Pore Pressure From Sonic Logs.

Two methods were used for obtaining pore-pressure estimates from sonic logs: Eaton’s approach and the SOPI method that uses sonic, offset well, porosity, and formation-resistivity data. Although resistivity logs were more prevalent than sonic logs in the Midland and Delaware Basins, the presence of both induction logs and laterologs was encountered; mixing the results from both data types would complicate workflow and interpretations.

Using Eaton’s approach, a shale normal compaction trend line varying with depth was established. Departures from this trend were used to compute pore pressure using observed sonic travel time.

For the SOPI method, wells with petrophysical multimineral model results that accurately characterized variations in lithology and porosity for the formations of interest were used. The sonic log response was forward-modeled using the derived mineral composition and porosity from petrophysical inversion.
Bamboo for Future
Authors: Yadav Alok
Published: February 2025

Bamboo, celebrated for its rapid growth and versatility, is emerging as a crucial resource in addressing key global challenges such as climate change, biodiversity loss, and economic inequality. Its high carbon sequestration capacity positions bamboo as a powerful tool for climate change mitigation, with certain species absorbing up to 62 tonnes of CO2 per hectare annually. Bamboo’s role in ecosystem restoration is equally significant, offering benefits like soil stabilization, water regulation, and habitat creation. Additionally, bamboo supports rural economies through sustainable industries such as construction, biofuels, and handicrafts. However, challenges remain, including gaps in research, a lack of standardized methodologies for carbon accounting, and the need for effective management to prevent ecological disruptions. Future efforts should focus on expanding research, developing global standards, and integrating bamboo into international climate policies to fully unlock its potential for environmental and economic sustainability.

Impact of Exogenous Sugars on the Potency of Selected Secondary Metabolites in Non-Starchy Amaranth (Amaranthus hybridus L.)
Authors: Iwuala Emmanuel
Published: February 2025

The biosynthesis of secondary metabolites plays a significant role in determining the value of medicinal herbs, with sugar metabolism frequently influencing overall metabolic processes. To investigate the regulatory mechanisms, exogenous sugars (sucrose, glucose, and fructose) were applied to the leaves of Amaranthus hybridus L., a highly valued and multifunctional vegetable plant, both individually and in combination (sucrose + glucose + fructose), along with a control (water). Our findings revealed that exogenous sugars enhanced the accumulation of starch and soluble sugars, while also increasing enzyme activities associated with carbohydrate assimilation. Additionally, plant biomass was significantly boosted by combined exogenous sugars, sucrose alone enhanced the photosynthetic rate, and the combined sugars accelerated the accumulation of phenols and flavonoids. Metabolomic analysis further confirmed that exogenous sugars increased the levels of phenolic and flavonoid compounds. The levels of UDP-glucose pyrophosphorylase (UGP) and hexokinase (HKX) were elevated by exogenous sugars and showed a strong correlation with their metabolic activities, which in turn stimulated the synthesis of specific secondary metabolites. These results provide valuable insights into the key factors contributing to the value formation of A. hybridus and suggest a potential approach to enhancing its quality.

Published: February 2025

Ukrainian universities operate under uncertain conditions and numerous challenges during wartime, significantly affecting their stability. This paper aims to identify and classify the key risks to the stability of Ukrainian universities during wartime and propose proactive tools for their mitigation. The study focuses on financial, personnel, and social risks, which are highlighted as the most critical under current circumstances. The data were sourced from the official websites of 10 universities, Open Budget, and the official websites of the Ministry of Finance of Ukraine and the State Statistics Service of Ukraine. The methodology combines theoretical analysis and statistical evaluation, including calculating marginal income – representing the portion of income covered by variable costs – and the operating margin ratio, defined as the ratio of marginal income to total income. Financial risks include a 7.9% reduction in education budget allocations, decreased subsidies, and insufficient state support. Personnel risks are analyzed through indicators, e.g., uncompetitive average hourly wages, leading to staff attrition and reduced motivation. The findings propose a multi-level classification of risks, categorizing them into external and internal with subcategories such as financial, personnel, and social ones. Non-traditional financial measures, such as unpaid leave and allowance reductions, were observed as short-term crisis strategies but require further evaluation to assess their long-term impact. The paper contributes to academic discourse by outlining challenges to university stability during wartime and providing a foundation for future research into effective risk mitigation strategies.

A népesedéspolitikával kapcsolatos elvárások és a családtámogatások ismertségének változása Magyarországon 2010–2016 között
Authors: Kapitány Balázs
Published: February 2025

Elemzésünkben a népesedéspolitikával kapcsolatos országos reprezentatív adatgyűjtések eredményeit hasonlítjuk össze. Annak ellenére, hogy a vizsgált időszakban több jelentős család- és népesedéspolitikai intézkedés került bevezetésre, kibővítésre, és a demográfiai témákkal a közbeszéd is hangsúlyosan foglalkozott, a kapott adatok szerint ezek a változások alig érzékelhetőek a népesedéspolitikával kapcsolatos vélekedések és az egyes családtámogatások ismertségének szintjén. Az értékekben, vélekedésekben megfigyelhető esetleges kisebb elmozdulások ráadásul nem minden esetben „logikus” irányúak. Ez arra utal, hogy a demográfiai kérdésekkel kapcsolatos vélekedések és ismeretek tekintetében meglehetősen nagy stabilitás uralkodik a magyar közvéleményben, a vélekedések csak kis mértékben befolyásolhatóak a közviták, illetve az egyes szakpolitikai intézkedések által. Ennél talán aggasztóbb az az eredmény, hogy a családpolitikai támogatási rendszer elemeinek ismertsége kapcsán szintén nem magas, és nem is növekvő eredményeket figyelhetünk meg. Ez utóbbi pedig gátja lehet a hatékony közpolitikáknak.
Ascorbic acid and calcitriol as alternative preventive strategies for myocardial damage in type 2 diabetes mellitus: an in vivo study using diabetic and atherosclerotic rat models
Authors: Saputra Jefri Dwi , Heriansyah Teuku , Sofyan Hamny , Dimiati Herlina , Mudatsir Mudatsir
Published: February 2025

BACKGROUND: Type 2 diabetes mellitus can increase the production of reactive oxygen species (ROS) and genetic transcription factors, such as nuclear factor kappa beta (NF-κB). These phenomena may enhance the progression of atherosclerosis. Additionally, NF-κB can induce apoptosis of pancreatic beta cells and accelerate disease progression.

OBJECTIVE: To investigate the role of calcitriol and ascorbic acid on NF-κβ expression in vivo in aortic and myocardial tissues of Wistar rats.

METHODS: This randomized experimental study involved 24 male Wistar rats of the Rattus norvegicus strain, divided into four groups: NC (negative control), PC (positive control), AG (ascorbic acid group), and CG (calcitriol group). The study spanned 90 days, including a 30-day intervention period. Aortic and myocardial samples were processed into histological preparations and stained using immunohistochemical techniques. NF-κB expression was assessed using an intensity scoring method.

RESULTS: The CG group demonstrated the lowest NF-κB immunoexpression in myocardial tissue (0.27 ± 0.08), followed by the AG (0.37 ± 0.05), NC (0.68 ± 0.08), and PC (1.13 ± 0.34) groups, with statistically significant 3sbetween the groups (p < 0.05). In aortic tissue, the CG group also exhibited the lowest NF-κB expression (0.30 ± 0.18), followed by the AG (0.50 ± 0.09), NC (0.97 ± 0.05), and PC (1.23 ± 0.38) groups, with statistically significant differences between the groups (p < 0.05). Similar trends were observed in the immunohistochemical staining of the NF-κB antigen in myocardial and aortic tissue samples. Calcitriol administration was more effective than ascorbic acid in reducing NF-κB expression in both myocardial (p < 0.05) and aortic tissues (p < 0.05).

CONCLUSION: Both ascorbic acid and calcitriol reduce NF-κB expression in the aorta and myocardium, with calcitriol showing greater effectiveness than ascorbic acid.

Keywords: Ascorbic acid, calcitriol, endothelial dysfunction, immunohistochemistry, antioxidant, NF-κB expression

Authors: Setiawan Dion , Prasetya Indra , Anjarwani Setyasih , Rizal Ardian
Published: February 2025

Background: Permanent right ventricular (RV) pacing is a standard for high-grade atrioventricular (AV) block treatment. However, it may result in left ventricular (LV) dilatation, systolic dysfunction, and heart failure (HF) as a consequence of ventricular dyssynchrony and an abnormal myocardial contraction pattern. Pacing-induced cardiomyopathy (PICM) can develop months or years after implantation of a permanent pacemaker (PPM) in patients who have long-term and high-burden RVP.

Case Illustration: We reported a case of a 56 years old Asian female having a record of PPM on VVIR mode implantation due to a high grade AV block presented with shortness of breath and bilateral leg swelling.

Conclusion: Echocardiography showed a significant decrease in LV systolic function less than two years after PPM implantation. Coronary angiography showed widely patent vessels; subsequently, His-Bundle Pacing (HBP) was scheduled on the patient.

Keywords: Atrioventricular Block, Right Ventricular Pacing, Pacing-induced Cardiomyopathy

The fermentation time plays a crucial role in the development of functional properties in fermented products, including kefir. This study investigates the effect of fermentation time on the nutritional, microbiological, and sensory properties of Roselle-based kefir popsicles. Fermentation times of 0, 18, 24, and 30 hours were analyzed for changes in acidity, viscosity, turbidity, fat content, ash content, Total Phenolic Content (TPC), Total Flavonoid Content (TFC), anthocyanins, antioxidant activity, calcium concentration, and Lactobacillus spp. population. Sensory evaluation assesses consumer preferences based on appearance, mouthfeel, flavor, aroma, color, and overall acceptance. The results showed that longer fermentation times, especially 30 hours, increased acidity, viscosity, and other nutritional parameters. However, popsicles fermented for 18 hours were most preferred by consumers due to their balanced sensory attributes. This study highlights the role of fermentation time in enhancing both the nutritional value and sensory appeal of Kefir Roselle-based popsicles, suggesting their potential as functional foods.

Authors: Sukirjo Sukirjo , Dwiningrum Siti Irene Astuti , Purwanta Edi , Sholeh Badrus , Sutikno Sutikno
Published: February 2025

School resilience must be strengthened for schools to be resilient and adaptable to change. To improve school resilience, change management is required. School resilience will be effective if it is supported by teacher and student resilience. Strengthening bonding, setting clear and consistent boundaries, teaching life skills, providing caring and support, set and communicating high expectations, and offering opportunities for meaningful participation are all components of school resilience. Individual resilience, on the other hand, consists of seven components: emotional regulation, impulse control, empathy, optimism, causal analysis, self-efficacy, and reaching out. If there is a synergy of work at the macro, mezzo, and micro levels, the school resilience policy will be formed. The objective of this research is to determine the level of school resilience and the change management strategies needed to strengthen the resilience of Indonesian schools in Jeddah, Saudi Arabia. The sequential explanatory mixed method approach (Cresswell) was used as the research method, and the subjects of this study were Saudi Arabia teachers and high school students. The findings of this study concluded that the average school resilience profile, as perceived by teachers and students, was in the moderately resilient category, which aligned with the individual resilience levels of teachers and students. In order to strengthen all aspects that must be owned by the school, such as the existence of fundamental values, synergy of social roles, development of competencies and skills, literacy knowledge, social punishment, and the existence of excellent programs designed by schools in a sustainable manner, the school must be able to apply the phases of change management supported by the synergy between roles.

Microteaching aims to ensure students as prospective educators deserve to experience real teaching-learning situations. However, in light of recent advancements in educational technology and the increasing integration of online learning, it has been carried out online. This study aims to analyze students’ competence of the online microteaching practice. This is classroom action research. Three determined indicators have become the basis to construct a questionnaire with a Likert scale. There are 132/150 students participating in this study. A descriptive statistical test was used to analyze the data, and students’ opinions were also recorded to strengthen the results. Almost all students (98.4%) pretty much understand the microteaching practice, and quite well (97.7%) understand how to use the online application for online microteaching practice, also they are satisfied (99.9%) with the quality of online microteaching practices. In simple real-life learning practices, of the 132 respondents, only 68.1% mastered the characteristics of their students, 60.6% applied learning tools, and 60.6% implemented periodic assessments.We concluded that students’ competence towards online microteaching practice is good, and they are aware of the advantages and disadvantages of conducting an online class. However, the skills demonstrated by students in online situations were different and inconsistent with those demonstrated in offline situations.

A learning model not only offers theoretical insights into environmental protection, but also encourages the practical application of justice value in the context of law enforcement. This study seeks to develop a law enforcement learning model based on Pancasila justice value to increase environmental awareness at Yogyakarta State University, Indonesia. The study employed a a mixed-methods approach, integrating qualitative and quantitative methods within a research and development (RD) design. The data were collected using questionnaires, observations, and document analysis. The population consisted of students who took civic education courses at Yogyakarta State University in 2023. A sample was selected using proportionate stratified random sampling, dividing the university’s faculties into groups based on cultural similarities, including the Faculty of Social, Legal and Political Sciences; Faculty of Economics and Business; Faculty of Education and Psychology; and Faculty of Languages, Arts and Culture. The results revealed three main findings. First, civic education at Yogyakarta State University required further development in terms of materials, methods, media, resources, and evaluation. Second, the development of a law enforcement learning model based on the justice value of Pancasila to increase environmental awareness involved initial, core, and closing activities. These activities included identifying environmental problems, introducing environmental law materials, selecting problems for class research, gathering and documenting information, developing class portfolios, presenting portfolios, and reflecting on the learning experience. Third, the model demonstrated effectiveness and had a significant impact on increasing student’s environmental awareness at Yogyakarta State University, effectively increasing their understanding in both theory and practice.

English-medium instruction (EMI) has become popular in educational settings worldwide and has attracted the attention of scholars, prompting scholars to investigate factors influencing student comprehension in EMI classroom.  It is important to understand the factors that influence student understanding in EMI classrooms. This paper identifies the factors influencing students' use of English in EMI classrooms. The data of the study was collected based on the results of interviews with English language teachers in Astana, and a thematic analysis was performed according to the methodology proposed by Braun and Clarke. It was determined that Task comprehension, Teacher's level of English, Terminology and Lesson Comprehension affect the students' English language comprehension according to teachers' perceptions. It was found that the identified factors can have both positive and negative effects. This study is aligning with broader issues on the internationalization of higher education and the growing prevalence of English as a global language (Fang et.al., 2023) It synthesizes research findings to identify key factors influencing student understanding in EMI classrooms from the perspective of teachers, highlighting key insights and further research recommendations.

This study investigated the academic experiences of visually impaired students at Hail University, addressing a critical gap in understanding accessibility challenges in Saudi higher education. The research aimed to identify barriers in three key areas: learning material accessibility, exam accommodation effectiveness, and faculty awareness of student needs. Using a qualitative phenomenological approach, semi-structured interviews were conducted with five visually impaired students, selected through purposive sampling. Data was collected through in-depth interviews and validated using member checking and peer debriefing techniques. Thematic analysis revealed several significant barriers: (1) inconsistent accessibility of digital course materials, with 80% of students reporting difficulties with PDF documents and presentation slides; (2) limitations in exam accommodations, particularly insufficient time allowances and inadequate screen reader compatibility; and (3) varying levels of faculty awareness, with only 20% of instructors proactively addressing accessibility needs. The study's novelty lies in its comprehensive examination of the intersection between digital accessibility, academic accommodations, and faculty preparedness in a Middle Eastern university context, providing insights previously unexplored in Saudi Arabian higher education. The findings contribute to developing evidence-based recommendations for improving institutional support systems and faculty training programs, ultimately enhancing educational experiences for visually impaired students in similar institutional contexts.

This study aims to (1) determine the necessity of a learning leadership model for vocational school principals to realize student well-being in the context of Merdeka Belajar, (2) develop a theoretically and empirically valid learning leadership model for vocational high school principals (SMK) to achieve student well-being within the context of Merdeka Belajar, and (3) assess the effectiveness of the learning leadership model for vocational high school principals in achieving student well-being within the Merdeka Belajar framework. This research employed the Research and Development method, consisting of four phases: the initial phase, the planning phase, the testing, evaluation, and revision phase, and the implementation phase. The testing subjects in this research were carried out in three stages, namely an initial trial involving 10 experts and education practitioners. Data collection techniques were conducted through focus group discussions, questionnaires, documents, observations, and interviews. The validity and reliability of the questionnaire instruments used expert validation. The validity of qualitative data was confirmed through informant review and data triangulation models. Quantitative data analysis was done using descriptive analysis techniques, while qualitative data was analyzed using an interactive analysis model. The research findings indicate that the KPK-SW model is highly necessary. The level of importance according to users, including the Head of the Education Department of DIY scored 4.44, school supervisors scored 4.39, evaluations from the Secondary Education Office scored 3.32, and education experts scored 4.38. The total average score is 4.38, meaning that this model is very important and suitable for use.

Published: February 2025

Air pollution poses a serious threat to public health and the environment, making accurate monitoring and prediction
crucial. This research focuses on Air Quality Index (AQI) prediction using machine learning (ML) techniques. We analyze
pollutant levels, including PM2.5, NO₂, CO, and O₃, along with meteorological factors such as temperature, humidity, and wind
speed. The dataset is collected from cloud-based sources, preprocessed, and split into 80% training and 20% testing sets [1].
Various ML models—Linear Regression, K-Nearest Neighbors (KNN), and Lasso Regression—are applied and evaluated using
Mean Squared Error (MSE) and Mean Absolute Error (MAE). The results demonstrate that KNN outperforms other models in
AQI prediction. This study highlights the potential of ML in environmental management, enabling timely interventions for air
pollution contro[2].
