Abstract

Low student’s problem-solving skills in the topic of alternative energy are reflected in their difficulties in understanding contextual problems and relating them to physics concepts. Therefore, the Cooperative Problem Solving (CPS) model integrated with the Two Stay Two Stray (TSTS) learning strategy was implemented as an alternative learning approach. This study is intended to analyze the improvement and the effect of integrating the TSTS strategy within the CPS model on students’ problem-solving skills. The research employed a quasi-experimental method with a Non-Equivalent Control Group Design involving two classes: an experimental class (CPS–TSTS) and a control class (CPS). The research instrument consisted of essay tests based on problem-solving skill indicators. The data were analyzed using N-gain calculation, independent sample t-test, and effect size analysis. The results indicate that both classes experienced improvement, with the average N-gain of the experimental class being 0.6722 and the control class 0.6250, both categorized as moderate. However, there was no significant difference in the improvement between the two classes. The integration of the TSTS strategy contributed to the improvement of students’ problem-solving skills, although the effect was still in the small category.

Abstract

The construction of the Jalur Jalan Lintas Selatan (JJLS) in Girijati Village, Purwosari District, Gunungkidul Regency, aims to improve regional connectivity but also has the potential to trigger land degradation and soil erosion. This study aims to map vegetation density and determine the land cover coefficient (C factor) as a basis for erosion mitigation. The method applied is remote sensing analysis using Landsat 8 satellite imagery from January 2026, processed with the Normalized Difference Vegetation Index (NDVI) algorithm. The results indicate that areas surrounding the JJLS development are predominantly characterized by moderate to sparse vegetation, particularly in the central and southern parts (DTH 1A and DTH 1B). In contrast, the northern area (DTH 2) is dominated by dense vegetation, which is relatively more resistant to erosion. These findings suggest the need for conservation strategies such as revegetation, terracing, and proper drainage maintenance in areas surrounding the road infrastructure to minimize surface erosion rates.

Abstract

The primary purpose of polymer injection is to reduce the water-oil mobility ratio. Commonly used polymers are polyacrylamide and polysaccharides. By increasing the viscosity of the injection fluid, polymer injection can improve sweep efficiency, thereby increasing oil recovery. Petroleum refining relies heavily on macroscopic and microscopic compression efficiency. This study aims to determine the compatibility test results between mesonapalustris and chitosan to determine whether good compatibility test results are obtained. The method used in this study is a laboratory experiment with observation. Compatibility was evaluated based on visual observation and qualitative stability indicators, with no effect across all salinity and concentration ranges. Quantitative indicators showed viscosity retention of >90% at and temperature. This demonstrates the potential of biopolymers as alternative agents in polymer flooding, with an increase in oil recovery of 15–20% OOIP.  Compatibility testing of polymer solutions in formation water is carried out to determine whether the polymer solution is completely soluble in the formation water. The test is carried out by dissolving the polymer in formation water with salinities of 10,000, 15,000, and 20,000 mg/L and polymer concentrations of 500, 1,000, and 2,000 mg/L. The solution is then placed in a bottle and observed for complete dissolution or sedimentation. Based on the results and discussions, experimental laboratory testing of black seaweed jelly and chitosan revealed compatibility results, which showed that all polymer solutions, both black seaweed jelly and chitosan, were compatible with various salinities of formation water, indicating that all polymer solutions were completely dissolved, no precipitation occurred and this suggests potential applicability of biopolymers as alternative agents in polymer flooding.

Abstract

This study aims to describe how a didactical design based on the Teaching at the Right Level (TaRL) approach, supported by flashcard media, can bridge third-grade students’ concrete and symbolic multiplication abilities at SDN 2 Labuapi. This research employed a qualitative method using a didactical scenario research design. The subjects of this study consisted of one third-grade teacher and 24 third-grade students at SDN 2 Labuapi. Data were collected through observation, interviews, and tests. The findings showed that in the first meeting, all levels achieved an average score of 100. In the second meeting, differences in average scores began to emerge across each level. The average score of the low level was 80, the medium level was 92.5, and the high level was 97.5. In the third meeting, students’ average scores showed further improvement. The average score of the low level increased to 95, while both the medium and high levels once again achieved a score of 100. In the fourth meeting, the average scores of the medium and high levels remained at 100, while the low level showed another improvement, reaching approximately 97.5. This study contributes significantly as a source of ideas and scientific literature for other researchers regarding the TaRL approach, conceptual representation, students’ cognitive processes, and the role of learning media.

Abstract

Drill spacing determination is one of the important aspects of coal exploration planning because it directly affects geological confidence, resource estimation, and exploration cost efficiency. This study was conducted on Seam F of the Muara Enim Formation in Musi Banyuasin Regency, South Sumatra. The objective of this study is to evaluate the quantitative variability of coal thickness and quality and to determine the optimum drill spacing as a basis for future exploration planning.  The analyzed parameters include coal thickness, ash content, total sulfur, and calorific value. The dataset consists of 115 collar points for coal thickness and 71 collar points for coal quality, with an average existing drill spacing of approximately 422 m. The methods used in this study include descriptive statistics, omnidirectional variogram analysis, global estimation variance (GEV), and relative error (RE). Drill spacing simulation was carried out using spacing scenarios ranging from 100 m to 3000 m to evaluate changes in estimation uncertainty with increasing drill hole distance. The results show that Seam F has an average thickness of approximately 3.19 m with a coefficient of variation (CoV) of 0.06, indicating low thickness variability. Coal quality parameters also show relatively low variability, with CoV values of 0.04 for ash, 0.05 for total sulfur, and 0.01 for calorific value. However, geostatistical analysis indicates that each parameter has different spatial continuity characteristics. Total sulfur has a nugget ratio of 11.7%, indicating relatively good spatial continuity, whereas calorific value has a nugget ratio of 60.8%, indicating stronger local variability. The GEV and RE analyses show that estimation uncertainty increases as drill spacing becomes wider. Based on RE thresholds for coal resource classification, the recommended optimum drill spacing for Seam F is 550 m for measured resources, 825 m for indicated resources, and 1,650 m for inferred resources. This study shows that the integration of descriptive statistics, variogram analysis, GEV, and RE can provide a quantitative and objective basis for determining drill spacing in future coal exploration planning.

Abstract

This study aims to describe the early literacy skills of first-grade students at SDN Inpres Kaworo, Bima Regency, and to analyze various teacher efforts in overcoming students' reading and writing difficulties. This study focuses on aspects of letter recognition, phonemic awareness, spelling ability, and basic writing skills as the foundation of early literacy in elementary school students. This research method uses a qualitative approach with descriptive methods. The research subjects consisted of first-grade students and class teachers at SDN Inpres Kaworo, Bima Regency. Data collection techniques were carried out through observation, interviews, and documentation to obtain a comprehensive picture of students' literacy skills and the learning strategies implemented by teachers. Data analysis was carried out through the stages of data reduction, data presentation, and systematic drawing of conclusions based on field findings. The results of the study indicate that students' early literacy skills are at various levels, especially in letter recognition, phonemic awareness, spelling ability, and early writing skills. These differences in abilities cause variations in students' learning speeds during the learning process. Literacy barriers found include difficulty distinguishing similar letters, limitations in spelling words, and errors in capitalization and letter shapes that do not comply with rules. Supporting and inhibiting factors are also influenced by learning motivation, student concentration, classroom conditions, and family support at home. Teachers' efforts include implementing phonics and syllabication methods, using letter and picture cards, repeated reading exercises, gradual writing exercises, and individual correction. Learning strategies are reinforced with a differentiated approach, strengthening motivation, and creating a conducive classroom atmosphere. Parental involvement also supports the improvement of students' literacy skills. The final results show a gradual improvement in basic literacy skills in first grade students.

Abstract

The low critical thinking ability of students is a significant problem in science learning in elementary schools, especially because learning is still dominated by conventional methods and the use of less interactive media. This condition results in a lack of active student involvement in understanding concepts in depth. Therefore, media innovations are needed that are able to integrate concrete visualization and interactivity. This study developed an Augmented Reality Flashcard media based on the Assemblr Edu application that not only emphasizes the feasibility aspect, but also tests the effectiveness of its use in learning. This study aims to determine the validity, practicality, and effectiveness of the Augmented Reality Flashcard learning media based on the Assemblr Edu Application to improve the critical thinking skills of sixth grade students at SDN 6 Sila. This research method uses the ADDIE development method consisting of five stages including analysis, design, development, implementation, and evaluation. The validation results of material experts obtained a score of 92%, and media experts obtained a score of 94% in the very valid category. The results of the student response questionnaire were 92.61%, and the teacher response was 85.45% in the very practical category. The results of the students' pretest and posttest using the N-Gain calculation obtained an N-Gain value of 0.66, which is in the moderate category, indicating an increase in students' critical thinking skills. Thus, it can be concluded that the augmented reality flashcard learning media is very valid, very practical, and effective.

Abstract

Land degradation is one of the main factors causing the decline in global biodiversity, which impacts ecosystem stability and the sustainability of environmental functions. Land restoration is a strategic approach in achieving ecosystem recovery while supporting the targets of the Sustainable Development Goals (SDGs), especially Goal 15 (Life on Land). This study aims to examine the effectiveness of various land restoration strategies through soil conservation, revegetation, and strengthening environmental legal aspects based on a literature review. The method used is a systematic literature review with a comparative analysis of previous studies from 17 selected studies encompassing global case studies from Asia, Africa, and Europe. The results of the study indicate that soil conservation is effective in reducing erosion by more than 50% and increasing soil moisture retention, mixed revegetation can accelerate biodiversity recovery compared to monoculture, while legal aspects play a role as a determinant factor in the sustainability of restoration although its implementation still faces institutional challenges. The research synthesis confirms that successful land restoration requires an integrated ecosystem-based approach, active human intervention, and strong and adaptive policy support.
