Abstract

This research aims to explore the ways in which teachers address the challenges of learning mathematics for children in primary schools by referring to behavioristic theory. This theory emphasizes the central role of stimuli and reactions in influencing learning behavior, and the application of both positive and negative reinforcement to improve students' motivation and understanding. The approach adopted was a descriptive qualitative method using case studies in various primary schools. The results indicated that behavior-focused methods, such as providing repeated practice of problems, immediate feedback, use of concrete tools, and regular application of rewards and punishments, can improve students' enthusiasm and mathematics learning outcomes. However, teacher-driven learning and lack of innovation are barriers to implementation. Therefore, a combination with other methods is needed to make the learning process more thorough.

Abstract

The low activity of students in biology learning is the main challenge in efforts to improve the quality of science learning in secondary schools. This study aims to analyze the effectiveness of the application of the Project Based Learning learning model in increasing student activity and learning outcomes in respiratory system materials at SMA Negeri 2 Langowan. This research is a Class Action Research that is carried out in two cycles, each of which includes stages of planning, action, observation, and reflection. The subjects of the study were 13 students in grade XI. The instruments used include student activity observation sheets and the final test of the cycle based on description questions. The results showed that in the first cycle, only 38.46% of students achieved learning completeness with an average score of 60. However, after improving the strategy in cycle II through active mentoring, learning motivation, and strengthening group work, completeness increased to 92.30% with an average score of 84.69. These findings indicate that the Project Based Learning learning model is able to build student activeness through contextual, collaborative, and hands-on experience-based learning. The increase in activeness is reflected not only in test results, but also in students' active participation in discussions, group presentations, and project completion. The implications of this study show that Project Based Learning is feasible to be implemented as an innovative learning strategy to improve the quality of student interaction and engagement in biology learning on an ongoing basis.

Abstract

The development of the education curriculum in Indonesia reflects a paradigm shift in strengthening scientific literacy, which plays an important role in shaping critical thinking patterns and student analysis to face the challenges of the 21st century. This study aims to examine the development of the concept of scientific literacy in the Indonesian national curriculum policy from the era of the School Level Curriculum (KTSP), the 2013 Curriculum, to the Merdeka Curriculum. The study was conducted through a literature study method on 20 relevant scientific articles published in the period 2013 to 2025. The results of the study show that scientific literacy in the KTSP is still implicit, limited to contextual learning approaches and direct experience. In the 2013 Curriculum, strengthening scientific literacy began to be realized through a scientific approach that encouraged students to develop critical thinking skills, understand scientific concepts, and carry out scientific processes systematically. Further transformation is seen in the Merdeka Curriculum, where scientific literacy is not only focused on cognitive aspects, but is also linked to character values ​​and contextual problem solving through strengthening the Pancasila Student Profile and project-based learning. In general, this study concludes that there is a paradigm shift from knowledge-oriented science literacy to holistic and applied science literacy. This finding emphasizes the importance of continuity between policy curriculum, teacher professional development, and implementation of strategies in the field to optimize students' achievement of science literacy.

Abstract

The low learning outcomes of students in Biology learning at SMA Negeri 1 Tutuyan is the background for the need for learning innovations that are able to increase active participation and conceptual understanding. This study aims to analyze the effectiveness of the Group Investigation learning model in improving student learning outcomes in Cell materials. The research used a pseudo-experiment method with a one group pretest-posttest design. The research sample amounted to 35 students from class XI Science who were selected purposefully. The instruments used were multiple-choice tests, pre-tests and post-tests of 25 questions for each test. The results showed an increase in the average score from 23.14 in the pre-test to 83.14 in the post-test. Inferential data analysis using the t-test showed a t-calculated value of 89.55, far above the t-table at a significance level of 5%. The category of student learning outcomes has also undergone significant changes, from a very low majority to a high and very high majority. The application of the Group Investigation model encourages students to be active in investigation, group discussions, and independent learning, which strengthens their collective and individual mastery of the material. These findings prove that the Group Investigation model is effective in improving learning outcomes, and can be implemented as a learning strategy in the Independent Learning Curriculum. This study contributes to the development of cooperative learning models in the context of Biology learning at the high school level, and can be replicated in other materials and levels to strengthen its effectiveness.

Abstract

The quality of human resources is an important aspect in regional development, which is reflected through the Human Development Index (HDI). HDI is influenced by various factors, including the economic conditions and education of the community. This study aims to analyze the effect of Gross Regional Domestic Product (GRDP) per capita and Average Length of Schooling (RLS) on HDI in South Kalimantan Province. The data used comes from the Central Statistics Agency (BPS) with a coverage of 13 regencies/cities during the period 2018 to 2023. The analysis method used is multiple linear regression with the help of R Studio software. The results of the study show that both GRDP per capita and RLS have a significant effect on HDI, both simultaneously and partially. The resulting model has an adjusted R² value of 0.8627, which indicates that 86.27% of the variation in HDI can be explained by these two variables. The classical assumption test including linearity, conditional zero error expectation, absence of multicollinearity, autocorrelation, homoscedasticity, and residual normality shows that the model used has met all the criteria as the Best Linear Unbiased Estimator (BLUE). Thus, this regression model is valid for use in estimating and making inferences on the factors that influence the HDI in South Kalimantan Province. This finding confirms that increasing education and economic growth are strategic steps in accelerating human development in South Kalimantan.

Abstract

Shrimp shell waste is a potential marine biomass resource rich in bioactive compounds such as astaxanthin and chitin, yet remains underutilized in the livestock sector. This study aimed to evaluate the effect of incorporating shrimp shell meal into duck (Anas sp.) feed rations on the yolk color intensity of duck eggs. The experimental design applied a completely randomized design (CRD) with a single factor and four treatments: D0 (100% rice bran, control), A1 (rice bran + 2% shrimp shell meal), A2 (rice bran + 6%), and A3 (rice bran + 10%), with a 21-day observation period. The primary parameter measured was yolk color intensity, assessed visually using a standardized color scale. The results indicated that the addition of shrimp shell meal significantly enhanced yolk color intensity, with the highest pigmentation observed in the A3 treatment. Astaxanthin, functioning as a natural carotenoid pigment, was biologically absorbed and distributed into the yolk via lipophilic pathways, while chitin supported gut health and nutrient absorption efficiency. This study aligns with the principles of the circular economy by valorizing marine processing waste as a functional feed ingredient. A 10% inclusion rate was found to be visually optimal; however, further studies are required to assess its physiological impacts and economic feasibility in broader production contexts.
