Abstract

This study aims to analyze the effect of guided inquiry learning strategies on students' critical thinking skills in ecosystem material at SMP Negeri 3 Wera. The research design used was a quasi-experimental design with a non-equivalent control group involving pretest and posttest in both the experimental and control groups. The data collection technique was carried out by distributing instruments in the form of critical thinking essay tests (pretest post-test) and observation sheets for student and teacher activities during the learning process. The data analysis technique used the Kolmogorov-Smirnov normality test and Levene's homogeneity test as prerequisite tests, then hypothesis testing (t-test) and N-gain to see the comparison between the pretest and post-test using SPSS-25.. The results showed that the critical thinking skills of students in the experimental group improved significantly compared to those in the control group. The N-Gain score of the experimental group was categorized as moderate, while the control group was categorized as low. The guided inquiry learning strategy effectively encouraged students to actively identify problems, develop hypotheses, collect data, and draw conclusions independently. This learning model can be applied effectively even in schools with limited resources.

Abstract

This research was conducted to respond to the need for the use of natural dyes that are more environmentally friendly and safer for health than synthetic dyes. One alternative is the use of natural dyes by utilizing the bark of the noni root (Morinda citrifolia Linn). The purpose of this research is to produce natural dyes from the bark extract of the noni root for use on ikat weaving yarn. The method used is a case study with the technique of thread washing stage, extraction and dyeing stage, color fixation stage, drying, observation of results, then the data is analyzed descriptively narrative. The results of the study show that extraction is carried out by the process of removing impurities in the yarn, dyeing fixation and drying. This natural dye extract is produced from boiling the bark of the noni root for 60 minutes and the dyeing is done traditionally and fixation is done using lime and tunjung as much as 1% which respectively produces a pink color on the lime and a reddish brown color on the tunjung. The use of the bark root of the noni can be used as an alternative natural dye for yarn used as the basic material for making ikat woven fabrics.

Abstract

This study aims to determine how vinega solution affects the structure and hardness of chicken thigh bones. Bones are composed of two main materials, namely calcium carbonate, which provides strength, and collagen, which makes them slightly flexible. When bones are immersed in a vinegar solution containing acetic acid, a chemical reaction called decalcification occurs, which is the dissolution of calcium carbonate from the bones. As a result, bones that were originally hard lose their mineral composition and become more flexible and easier to bend because only elastic collagen tissue remains. In the experiment, chicken bones were soaked in vinegar for five days, then changes in color, texture, and bone hardness were observed. The results showed that the bones became softer, paler in color, and less likely to break when bent. Through this experiment, it was understood how a simple chemical reaction can change the physical properties of hard objects such as bones, as well as providing insight into the importance of calcium in maintaining bone strength. This experiment also taught the close relationship between chemistry and biology in practical terms in everyday life.

Abstract

This study aims to identify the level of flora and fauna diversity in the Puncak Harfat tourism area, Kampung Usaha Jaya, East Misool District, Raja Ampat Regency, Southwest Papua. The research employed a mixed-method approach, combining qualitative and quantitative techniques in data collection and analysis. The study was conducted over one month in March 2025, with samples consisting of all flora and fauna found in the eastern part of Puncak Harfat. Data were collected through field observations and interviews, and then analyzed using the Shannon–Wiener Diversity Index, Simpson’s Dominance Index, and Margalef Species Richness Index. The findings revealed 21 species of flora, with orchids and Nepenthes mirabilis identified as dominant species, highlighting the significance of this area as a natural habitat for local flora conservation. For fauna, 15 species were identified, dominated by marine biota such as corals (Acropora, Staghorn Coral) and Amphiprioninae fish, reflecting a diverse ecosystem. The diversity indices of flora (H’ = 2.6721) and fauna (H’ = 2.330) indicate moderate to high categories, while the dominance indices for flora (C = 0.3006) and fauna (C = 0.2655) show no extreme dominance of a single species. Margalef’s richness indices (R = 5.14 and R = 3.44) further confirm the high species richness in the area. Thus, these findings affirm that the Puncak Harfat ecosystem is stable, productive, and suitable to be maintained as a biological conservation site.
