Abstract

This research aimed to study spatio temporal behavior of the female ricefield rat, Rattus argentiventer, including home range, range spans, habitat use and daily activity. Twelve rats were released in two locations of a ricefield area from June 11th until July 24th, 2001. The movement of each rat was monitored using radio-tracking three times a day. The result was used for calculating home range size, range spans, habitat used and daily activities of female field-rats, using the computer program Ranges V. The results showed that the average female ricefield-rat’s home ranges and range spans were 0.84  0.16 Ha and 184.54  22.7m respectively. During daylight, the rats spent 82%, 16% and 2% of their activity living in dikes, in villages and in ricefield respectively. On the contrary, during the night 95%, 3% and 2% of the rats were active in the ricefield, villages and dikes respectively.

Abstract

This study aims to explore the understanding and application of the integration of Islamic values ​​in mathematics learning in elementary schools. Using a descriptive qualitative approach with a phenomenological design, this study involved interviews, observations, and documentation to obtain the views of mathematics teachers who teach in elementary schools with a religion-based curriculum. The results showed that teachers' understanding of the integration of Islamic values ​​varied, with some teachers emphasizing more on ethical and moral aspects, while others focused on spirituality and the order of the universe reflected in mathematics. The integration of values ​​such as honesty, patience, and responsibility is considered to be able to enrich students' understanding of mathematics material while shaping their moral character. However, the challenge faced is how to effectively connect mathematical concepts with religious values ​​in the existing curriculum. Active and project-based learning methods have proven effective in integrating Islamic values, although teachers still face difficulties in implementing them. This study is expected to contribute to the development of learning models that integrate religious values ​​in mathematics education in elementary schools.

Abstract

Learning is evolving rapidly in the 21st century, as evidenced by advancements in science and technology (IPTEK), including the use of comics as a medium for learning mathematics. The incorporation of ethnomathematics comics based on the architectural features of Masjid Al-Akbar Surabaya serves as an innovative learning tool to address issues such as unengaging media and students’ reluctance to learn mathematics. This study aims to: (1) examine the process of developing ethnomathematics comics about the Al-Akbar Mosque of Surabaya to help elementary school students recognize the names and characteristics of geometric structures; (2) assess the feasibility of these comics as a learning medium; and (3) analyze teachers' and students' responses to their implementation in the classroom. This study employs a research and development (R&D) approach using the ADDIE development model, which consists of four stages: analysis, design, development, and implementation. Data collection methods include documentation, surveys, observations, interviews, and literature reviews, while data analysis combines qualitative descriptive and quantitative techniques based on expert validation and Likert-scale responses. The results indicate that (1) the three initial stages of the research process—analysis, design, and development—were successfully carried out according to the established framework; (2) validation data from material experts, linguists, and learning media specialists rated the comics as "highly feasible"; and (3) responses from class II-A teachers, expert teachers, and four class II-A students also confirmed a "highly feasible" rating. These findings suggest that the developed ethnomathematics comics based on the Al-Akbar Mosque are effective and appropriate for elementary school students in learning about geometric structures. This research contributes to mathematics education by integrating ethnomathematics into instructional media, fostering cultural appreciation while enhancing students' understanding of geometric concepts. Additionally, it provides a structured framework for developing ethnomathematics-based learning resources that can be adapted to other cultural and architectural contexts.

Abstract

Effective education requires an approach that encourages ability to analyze critically, particularly when learning mathematics which is often considered challenging by students. Problem Based Learning model is considered capable of developing students' critical thinking abilities through real problem solving and collaboration. The purpose of this study is to find out how the Problem Based Learning approach affected the critical thinking abilities of Grade X students at SMAN 1 Driyorejo in the subject of arithmetic sequences throughout the 2024–2025 school year. The research employs an appropriate experimental design, namely the pretest-posttest control group design, and takes a quantitative approach.. The sample includes two classes: class X-6 as the experimental group implementing the Problem Based Leaning model, and class X-7 as the control group applying conventional teaching methods. Critical thinking assessments were used to gather data both before and after the intervention. To ascertain whether there was a significant difference between the two groups, the data were examined using a t-test. The findings indicated that the average pretest scores for the control and experimental classes were 31,91 and 58,71, respectively, while the average posttest scores were 46,48 and 90,05. Before testing the hypothesis, students' critical thinking test scores must be checked for normality and homogeneity to ensure the data is normally distributed and has the same variance. The data analysis's findings demonstrate the worth of t_count>t_table, result is |-19,826>-1,995 | for pretest questions and the value of t_count>t_table, result is |-48,278>-1,995| for posttest questions. Thus, when compared to conventional teaching approaches, the data analysis results demonstrate that the Problem Based Learning model significantly improves students' critical thinking abilities.Keyword: Problem Based Learning, Critical Thinking Abilities, Arithmetic Sequence

Abstract

Hematoxylin-eosin is widely utilized in the field of animal microtechniques. However, the need to develop alternative dyes from natural sources such as plants has gained attention. Several studies have shown that many plants contain secondary metabolites with the potential to be developed as natural dyes. Lonchocarpus cyanescens and Syzygium cumini are promising candidates as alternative dyes for hematoxylin, while Lawsonia inermis and Hibiscus sabdariffa have shown potential as substitute dyes for eosin. These plants contain various secondary metabolites, including anthocyanins, flavonoids, chlorophyll, betalains, alkaloids, saponins, tannins, carbohydrates, proteins, phenolics, terpenoids, quinones, coumarins, xanthones, and resins. L. cyanescens exhibits a strong binding affinity to cells and tissues, particularly testicular tissue. Dyes derived from Syzygium cumini have been shown to provide a good staining result for rat liver cells. In contrast, dyes from Lawsonia inermis can stain cytoplasmic components and muscle fibers. Additionally, the dye from Hibiscus sabdariffa is capable of staining various biological components, including sperm, nerve cells, and blood cells. The dye preparation process involved extraction from different plant organs, such as leaves, flowers, and fruit. These findings suggest that secondary metabolites from these four plants hold significant potential for development as natural dyes to replace hematoxylin-eosin in histological applications.

Abstract

This research aims to calculate thoroughness among data points and analytical simulation curves in discussing corona discharges' (I-V) characteristics. The electrode construction used is the twin towers with dividing angles to the plane (TTDA-P) model in air, with negative DC polarity. An asymmetrical electrical CCP model in the electrode design uses research variations, including active electrode center clamp angles of q = 300, 450, and 600 and active and passive electrode distances (d) of 0.002 m, 0.005 m, and 0.008 m. The simulation curve comes from the analytical formulation of the reduced capacitance type (inserting a multiplying factor k to the sharp corners of the active electrode), with the simulation program being a Python GUI program. The experimental results produced an appropriate error value (t-test value £0.05) and a high percentage of tangent points value. The best curve was achieved at q = 450 and d = 0.008 m, with a t-test value of 0.0313 and the highest percentage of significant tangent points of 92.31%. For all variations q, there is a tendency that the smaller the value of d (the gap length among two electrodes), the greater the deviation distance between the simulation curve and the data points.

Abstract

This study aims to describe students’ critical thinking abilities in solving numeracy problems in terms of four learning styles: activist, theorist, pragmatist, and reflector. A qualitative descriptive approach was employed, involving students who represent each learning style as classified by the Honey and Mumford model. Data were collected through numeracy tests and in-depth interviews to explore students' reasoning processes and critical thinking indicators. The findings indicate that students with an activist learning style tend to excel in the reasoning indicator, as they are able to explain their problem-solving strategies clearly and appropriately. However, their solutions often lack thoroughness, with some steps being overlooked. Students with a theorist learning style show strengths in the inference indicator, demonstrating the ability to provide logical explanations and clearly articulate cause-effect relationships. Those with a pragmatist learning style also lean towards the reasoning indicator, offering straightforward and practical explanations of their chosen strategies. Meanwhile, reflector-type learners display a preference for the inference indicator as well, outlining their steps but expressing uncertainty and hesitation in their answers. In conclusion, students’ critical thinking abilities in numeracy tasks are influenced by their learning styles, with each style showing a different emphasis on specific critical thinking indicators. This research contributes to the field by: (1) providing insights into the relationship between learning styles and critical thinking indicators in the context of numeracy; (2) informing educators on how to tailor instructional strategies to align with students’ learning styles in order to enhance critical thinking; and (3) offering a foundation for future studies aimed at developing numeracy-based learning tools that accommodate diverse learning preferences.
