Abstract

This study is conducted to investigate the improvement of inquiry ability variation of students after applying inquiry learning model in 30 Junior High School, Makassar. Inquiry variation is amount of counseling intensity or guidance that is given by teacher in a learning. Inquiry variation can be seen based on five inquiry essential features such as applying question, deciding and collecting relevant evidence, making explanation based on the evidence, connecting the explanation with scientific references and communicate it. This research uses documentation study method. The sample of the research are 74 students of seventh grade that are taken by using random class sampling technique. Data collection technique uses observation sheet of inquiry ability variation. The data processing technique uses descriptive method. Data analysis result shows the improvement in five inquiry essential characteristics. It can be seen in the comparison between the first and the last meeting. In the first meeting, all of the inquiry essential characteristics were given by teacher, while in the last meeting, students can do the characteristics by themselves. However, it is only one characteristic that still need guidance from teacher like essential characteristic in deciding and collecting relevant evidence. The result of the study shows that the application of inquiry learning model can help students in improving inquiry ability variation that is better than the using of conventional learning model.

Abstract

This study aims to analyze the characteristics of the items based on the classical test theory approach. This research is exploratory research with a quantitative approach. The data used in this study were data from the 2015 Science Subject National Examination for Junior High School in Daerah Istimewa Yogyakarta (DIY) province. The samples taken in this study were 9054 students. Test takers are grouped into high groups and low groups based on the total score obtained. Estimation of item parameters using Excel and QUEST. The results of the analysis show that based on the classical test theory approach, the average item difficulty level ) in the high group is in the easy category, while in the low group, it is in the medium category, the average item differential index ( ) shows that the test ability to distinguish students with high abilities and low abilities in both the high and low groups is in the unfavorable category; and the reliability coefficient of the test (ρ) in the high group has high reliability, and the low group has perfect reliability

Abstract

Purpose of the study: This study aimed to develop and optimise a technologically relevant non-thermal acid-induced maturation process for giant gourami by identifying effective citrus acid formulations and immersion durations that enable controlled myofibrillar protein denaturation for scientifically standardised and traditional Dekke Naniura processing. Methodology: A laboratory-based semi-controlled experimental design was applied using fresh gourami fillets immersed in organic acids derived from lime (Citrus aurantiifolia) and lemon (Citrus limon) juices at different ratios and immersion times. Maturation progression was evaluated using a semi-quantitative visual index (0–100%) supported by triplicate mean ± SD measurements. Observations included colour transformation, flesh firmness, and macroscopic protein denaturation, while microscopic assessment and mechanical texture analysis validated structural myofibrillar changes. Statistical analysis using one-way ANOVA and Tukey’s HSD determined significant treatment differences. Main Findings: The optimal condition was a formulation containing 75% lime juice and 25% lemon juice with an immersion duration of 1,140 minutes, achieving 96% maturation. This treatment produced homogeneous myofibrillar protein denaturation, uniform colour transformation, and increased flesh firmness under non-thermal conditions. Single-acid treatments showed slower and less uniform maturation, indicating a synergistic effect of mixed citrus acids. The dense muscle fibre structure and high myofibrillar protein content of gourami contributed to enhanced structural stability during maturation. Statistical analyses confirmed significant differences among treatments at most immersion times. Novelty/Originality of this study: This study proposes a reproducible and chemically optimised non-thermal maturation model integrating semi-quantitative, microscopic, and mechanical analyses, providing a scientifically validated framework for modern adaptation of traditional Batak naniura processing.

Abstract

Indigenous marine resource management provides culturally embedded knowledge that can enrich contextual science education and promote sustainability awareness. However, the scientific reconstruction of customary marine practices into structured science learning resources remains limited. This study aimed to reconstruct the ethnoscience knowledge embedded in sasi lola (Trochus niloticus) on Sermata Island, Southwest Maluku, Indonesia, and map its relevance to contextual junior secondary science learning and sustainability awareness. An ethnographic approach was employed in Regoha Village, with three purposively selected key informants representing customary, religious, and village authorities. Data were collected from May 2026 through participant observation, semi-structured interviews, and documentation. Data were analyzed using Spradley’s domain, taxonomic, componential, and cultural-theme analyses, supported by source and method triangulation, member checking, and expert review. The findings indicate that sasi lola integrates ecological, technical, normative, and institutional knowledge through seasonal closure–opening cycles, collective harvesting restrictions, molo (diving) practices, customary sanctions, and community benefit sharing. These practices were reconstructed into science concepts related to animal growth and reproduction, population, habitat, biodiversity, abiotic factors, and hydrostatic pressure, and connected with environmental, social, and economic dimensions of sustainability awareness. The resulting reconstruction matrix demonstrates the potential of sasi lola as a culturally relevant and contextual science learning resource for archipelagic schools.
