Abstract

This study aims to analyze the effectiveness of the question-and-answer method in mathematics learning. The research method employed is a literature review using a descriptive qualitative approach. Findings from several relevant studies indicate that the question-and-answer method enhances students' learning outcomes, fosters active participation, and strengthens critical thinking and communication skills. Variations in its implementation, such as multi-directional questioning, chain questioning, and experiment-based questioning, enrich classroom interaction and help students grasp abstract mathematical concepts. Furthermore, the method promotes an interactive learning environment where students are encouraged to think critically, reflect on their understanding, and actively engage with their peers. The collaborative nature of the question-and-answer technique supports the development of social skills, making it an effective tool for both cognitive and social learning. Therefore, the question-and-answer method can be considered an effective instructional strategy to improve the quality of mathematics learning, particularly in enhancing problem-solving abilities, fostering a deeper understanding of mathematical concepts, and improving student-teacher interactions.

Abstract

The Human Development Index (HDI) functions as a key indicator for assessing the level of welfare and overall quality of life of the population within a specific region. This study aims to examine the socio-economic factors influencing HDI at the provincial level in Indonesia using a Gaussian kernel regression approach. A nonparametric method is employed due to its flexibility in capturing nonlinear relationships between the response and predictor variables without the need to assume a specific functional form. The analysis utilizes secondary data, including education, poverty, per capita expenditure, expected years of schooling, open unemployment rate, and gross regional domestic product for each Indonesian province. The findings from this study indicate that educational factors, particularly mean years of schooling and expected years of schooling, exert the most significant impact on HDI improvement. The estimated Gaussian kernel regression model demonstrates a coefficient of determination of 0.9954 and a residual standard error of 0.3468, reflecting a very high predictive accuracy and relatively low error. These results suggest that Gaussian kernel regression is an effective nonparametric approach for analyzing human development in Indonesia.

Abstract

The shrimp farming industry in Indonesia is predominantly dominated by Vannamei shrimp (Litopenaeus vannamei), also known as white shrimp. This shrimp species is favored due to its fast growth rate and high economic value. However, the intensive farming practices often lead to various diseases, particularly those caused by parasitic infections. Ectoparasitic infections can create wounds on the shrimp’s body, making it easier for other pathogens like fungi, bacteria, and viruses to invade. This study aims to identify the types and levels of ectoparasite infestations on Vannamei shrimp to understand their impact on shrimp health and farm productivity. The research method used is a literature review, gathering data from various sources such as scientific journals, books, research reports, and technical notes related to shrimp farming. The findings of the study show that the presence of ectoparasites can serve as an important indicator to assess the health of the farming environment. High levels of parasitic infestations indicate suboptimal environmental conditions, such as poor water quality or improper management practices. Therefore, early identification of ectoparasites is crucial to prevent the spread of diseases and ensure the sustainability of Vannamei shrimp farming in Indonesia.

Abstract

Mathematics anxiety is a psychological barrier that negatively affects students’ performance and self-confidence. A valid and reliable measurement tool is required to identify this condition accurately. This study aims to examine the construct validity of the Mathematics Anxiety Rating Scale 30 (MARS-30) using a Monte Carlo simulation approach. The research employed first-order confirmatory factor analysis (CFA) through R software with a simulated sample of 300 respondents. The findings revealed that the overall measurement model achieved excellent fit indices, as indicated by Normed χ², RMSEA, SRMR, and CFI, all within the optimal range. Nevertheless, only 8 out of 30 items (26.7%) met the validity criteria, while the remaining 22 items were found invalid. This result suggests that although the global model fit was adequate, most items of MARS-30 did not consistently represent the construct of mathematics anxiety. The implication of this study highlights the necessity of revising the instrument by refining item wording, adjusting indicators, and conducting further testing to ensure stronger construct validity. A more valid instrument will enable educators and researchers to design targeted pedagogical interventions for reducing mathematics anxiety and supporting students’ learning outcomes.

Abstract

Mathematics learning plays an essential role in developing students’ logical, systematic, and analytical thinking skills. One of the higher-order thinking abilities that serves as a main focus in mathematics education is mathematical reasoning. This ability is closely related to the process of mathematical proof, which functions to justify the truth of a statement logically. This study aims to examine the relationship between the understanding of proof concepts and the development of mathematical reasoning among junior high school students through a library research approach. Data were obtained from various sources such as textbooks, journal articles, research findings, and relevant educational documents. The analysis was conducted using the content analysis method to review both conceptual and empirical findings from the literature. The results indicate that understanding the concept of proof not only helps students comprehend the logical structure of mathematics but also contributes to the development of deductive and reflective reasoning skills. Engaging in proof activities enables students to shift from merely imitative reasoning toward independent logical construction (creative reasoning). However, teaching proof at the junior high school level still faces several challenges, such as students’ limited understanding of basic logic, time constraints, and the lack of teacher training in teaching proof effectively. Therefore, learning strategies that emphasize students’ thought processes, provide opportunities for exploration, and integrate proof activities into meaningful learning contexts are needed.

Abstract

The growing demand for natural, sustainable personal care products has driven interest in perfumes formulated with plant-based essential oils and natural fixatives. This study aims to develop and evaluate base-note perfumes using essential oils extracted from three Indonesian aromatic leaves—lemongrass (Cymbopogon citratus), basil (Ocimum basilicum), and kaffir lime (Citrus hystrix)—combined with jasmine (Jasminum sambac) oil as a fixative. Essential oils were extracted by hydrodistillation, and three formulations were prepared, each containing a 30:70 blend of essential oil to ethanol. The perfumes underwent organoleptic testing by 15 trained panelists, along with evaluations of fragrance longevity (over 12 hours) and stain effects on paper substrates. Among the formulations, the blend of kaffir lime and jasmine (Formula 2) exhibited the highest average scores across sensory parameters, including fragrance intensity and freshness. It also retained a perceptible aroma for more than 12 hours and showed minimal staining. The results indicate that natural perfumes made with local essential oils and jasmine fixatives can meet consumer expectations for quality and performance. This study highlights the potential of Indonesian aromatic plants in sustainable perfumery and suggests avenues for future innovation in natural fragrance design.
