The Effect of Problem Based Learning Model Based on Problem Solving Strategy on Critical Thinking Ability
Full text linkPhysics instruction that relies solely on conventional learning models is one of the factors contributing to students’ low critical thinking skills. This study aimed to examine the effect of the Problem-Based Learning (PBL) model based on a Problem-Solving Strategy on the critical thinking skills of eleventh-grade students at State Senior High School 2 Merauke in the topic of particle motion dynamics. This quantitative study employed a quasi-experimental research method using a pretest–posttest control group design. The sample consisted of class XI-4 as the experimental group and class XI-6 as the control group, selected through purposive sampling. The research procedure comprised three main stages: the preparatory stage (problem identification, literature review, development of instructional modules, and construction and validation of research instruments), the implementation stage (administration of the pretest, implementation of the intervention, and administration of the posttest), and the final stage (data analysis and formulation of conclusions). This study adopted Facione’s indicators of critical thinking skills, based on their relevance and alignment with the operational definition of critical thinking employed in this research. The results showed that the experimental class achieved a higher percentage than the control class, demonstrating that the PBL model based on a Problem-Solving Strategy had a greater impact on improving critical thinking skills compared to conventional learning models

Passion Or Pressure? A Closer Look At How Gen Z Relates To Their Work
Full text linkGen Z is widely portrayed as a generation that seeks meaning and personal fulfillment in their work. But does this truly stem from genuine passion—or from internal and social pressures? This study investigates Gen Z’s work motivation by comparing two forms of work passion: harmonious and obsessive. Using data from 422 Gen Z employees across Indonesia, collected via online surveys, a paired sample t-test revealed that respondents reported significantly higher levels of harmonious passion (M = 26.22, SD = 4.80) compared to obsessive passion (M = 21.45, SD = 5.14), t(421) = 22.77, p < .001, with a large effect size (d = 1.11). These findings suggest that Gen Z is more likely to pursue work as a self-directed, meaningful endeavor rather than one driven by pressure or identity attachment. The study offers a timely reflection for Gen Z on the nature of their work engagement and provides organizations with practical insights on how to attract and retain passionate young talent. This research contributes to the broader discourse on generational work values and highlights the importance of fostering authentic motivation in the emerging workforce
Salvaging The Marginalized: Supporting Service Teachers’ Skills in Extensive Reading Pedagogies for Nomadic Pastoralist Children in Kenya
Full text linkThe societal impacts of enhancing teacher capacity in the underserved Arid and Semi-Arid Lands (ASAL) are significant in improving education policy and practice; yet, few studies have investigated the continuous professional support that teachers need to provide quality and inclusive education in such contexts. This research reports on the implementation of a teacher capacity-building action research project aimed at supporting primary school children's Extensive Reading (ER) activities in the context of underserved and least developed areas of the ASAL in Lodwar, Turkana County, Kenya. The trainees in the ER programme were 30 teachers from ten primary schools. Study results indicate that teachers were able to help learners develop self-directed ER, which was a positive step towards initiating a reading culture in English as a Second Language (ESL). Moreover, the reading comprehension results showed that ER had somewhat gradual significance in increasing ESL learning outcomes. However, students’ motivation to read requires the sustained development of new reading strategies, accompanied by a continuous monitoring plan, to achieve considerable improvement
Identifikasi Degradasi Tutupan Lahan dan Kerapatan Vegetasi di Kabupaten Murung Raya Melalui Algoritma NDVI: Identification of Land Cover Degradation and Vegetation Density in Murung Raya Regency Using the NDVI Algorithm
Full text linkABSTRACT
As a strategic upstream area of the Barito River, Murung Raya Regency currently faces serious environmental challenges due to massive land clearing and development activities. This study aims to analyze the condition and density of vegetation in Murung Raya Regency using the Normalized Difference Vegetation Index (NDVI) from 2023 Landsat 8 satellite imagery. The results show that the total study area is 20,211.68 Ha, which is heavily dominated by Non-Vegetation (44.19%) and Very Low Vegetation (44.18%) classes, totaling 17,864.54 Ha or 88.39% of the total area. Spatially, these low NDVI values strongly correlate with bareland, infrastructure networks, and land clearing activities. Meanwhile, high-density forest only accounts for 8.84%, primarily in the northern region. These findings emphasize the urgent need for spatial planning policy evaluation and forest area protection in the upstream to ensure the sustainability of ecological functions in the future.

Variasi Tekstur Tanah dan Bahan Organik Berdasarkan Kerapatan Tajuk Studi Kasus pada Hutan Kota Muhammad Sabki, Kota Jambi: Variation of Soil Texture and Organic Matter Based on Canopy Density A Case Study in the Muhammad Sabki City Forest, Jambi City
Full text linkABSTRACT
This study aims to examine the variation in soil texture and organic matter content across different canopy density levels in Muhammad Sabki Urban Forest, Jambi City. A purposive sampling method was applied to determine three plots based on canopy density (dense, moderate, sparse). Soil texture was analyzed based on sand, silt, and clay fractions, and organic matter content was obtained from secondary data. The results show that soils in dense and moderate canopy plots were dominated by clay textures and had higher organic matter content, at 7,28% and 6,40% respectively. In contrast, sparse canopy plots exhibited more varied textures and lower organic matter content (5,05%). Higher canopy density tends to increase organic matter accumulation and influence finer soil textures.

Navigating professional identity: A case study of Indonesian EFL non-certified teachers
Full text linkThe Indonesian government has enhanced educational quality and teacher professionalism via teacher certification. This research investigates the professional identity of Indonesian EFL (English as a Foreign Language) teachers, who have not been certified, and how they perceive their teaching career and professionalism. This research employs a qualitative case study design to explore the reflective practices of ten teachers who do not possess certification (or have not undergone a certification program). The data collection involved two primary methods: a modified questionnaire comprising six aspects of teacher professional identity and semi-structured interviews. The research findings suggest a tough professional identity beyond formal credentials, particularly the satisfaction and fulfilment of teachers without certification. Collaborative initiatives between the government, educational institutions, and relevant stakeholders are suggested to create a more conducive and rewarding teacher environment

Cooperative principles in Markobar oral tradition: A socio-pragmatic study for cultural education
Full text linkThe research aims to examine the form of maxims violation in “Markobar” activity, review the factors of violations, and identify the main reasons from a socio-pragmatic perspective for cultural education. The research design is descriptive-qualitative approach. The data were obtained from sentences on Markobar activities in the book “Panduan Markobar dalam Budaya Mandailing” comprising 25 texts as well as interviews with participants. Violations of the cooperative principle in the oral tradition of Markobar occur for several reasons, i.e., 1) Flouting maxim. This occurs by expressing gratitude to God and greeting the Prophet Muhammad. Speakers tend to hide things due to cultural factors; 2) Infringing maxim is not found; 3) Opting out of maxim, the speaker is not willing to provide information to the interlocutor in a straightforward manner; 4) Suspending maxim, listener should not expect to hear but the speaker clarifies what he means to make the interlocutor understand. Research in socio-pragmatic studies needs to be carried out to explain its intentions, objectives as a cultural education and revitalization.
