Abstract

The purpose of this study was to determine the effect of the discovery learning model on students' critical thinking skills in the IPAS (Science and Social Studies) subject, specifically on the topic of the States of Matter and Its Changes.The research method employed was a Quasi-Experimental design using the Non-equivalent Control Group Design. The study was conducted in the 4th grade of Madrasah Ibtidaiyah Islamiyah Ciwaru, where students were divided into an experimental group (receiving the discovery learning treatment) and a control group. The object of this research was the students' critical thinking skills. Data collection techniques included essay tests in the form of pretest and posttest, as well as observation. Data analysis was performed quantitatively using the t-test to determine the significance of the difference in the mean scores of the pretest and posttest between the two groups. The results showed a significant increase in critical thinking skills in the experimental class. The mean posttest score for the experimental class (86.63) was substantially higher compared to the control class (63.27). Based on the t-test analysis, the difference in the pretest and posttest scores between the two groups was significant, with a significance value (2-tailed) of 0.000 (p 0.05). The conclusion of this study is that the implementation of the discovery learning model is effective and can improve the critical thinking skills of 4th-grade students on the topic of the States of Matter and Its Changes.

Abstract

The purpose of this study is to determine the diversity of taro plants in the Sayal village area of the Saifi district in Sorong regency. The type and design of this study is descriptive exploratory, which aims to describe the diversity of taro plants. It was conducted in May 2022, in the Sayal village area of the Saifi district, South Sorong regency. The sample for this study was all taro plant varieties classified under theColocasia genus.  Data collection was carried out through the selection of study objects (STO) and the observation and scoring of taro morphological characters. Data were analyzed quantitatively using descriptive methods by calculating the similarity index to determine the level of similarity and varietal diversity. The results of this study can be summarized as follows: there are three types of taro plants in the Sayal village area of the Saifi district, Sorong Regency, from three villages, namely Komagaret village(Bogor taro), Baibet village (Belitung taro), and Sayal village(swamp taro).

Abstract

The study aims to determine the effect of tea dregs waste on the growth of pak choy plants. The study was conducted using quantitative methods and a Completely Randomized Design (CRD) with four tea dregs dosage treatments, namely 0 grams, 40 grams, 60 grams, and 80 grams per liter of nutrient water, each with three replications. The parameters observed included plant height, number of leaves, and fresh weight of the plant. Data were collected using an observation sheet, then analyzed using ANOVA at a significance level of 5 percent, followed by Duncan's test to determine significant differences between treatments. The results showed that the provision of tea dregs waste had a positive and significant effect on the growth of pak choy (p 0.05). The 80 gram treatment (P3) produced the best growth with an average plant height of 6.3 cm, number of leaves 7.1 strands, and fresh weight 7.4 grams. Increasing the dose of tea dregs increased the availability of macronutrients such as nitrogen, phosphorus, and potassium, thereby supporting photosynthetic activity, vegetative tissue formation, and increasing plant biomass. Despite showing positive results, the use of tea dregs in this study served as a nutritional supplement and cannot fully replace commercial hydroponic nutrients.

Abstract

This study aims to examine the application of a maritime ethnoscience approach in science learning through a systematic literature review (SLR) of publications from 2017 to 2025. Of the 60 articles searched through Google Scholar and Scopus, 21 passed the selection process based on the inclusion criteria. The analysis shows that most studies focused on junior high school students, utilizing direct ethnoscience learning models, 4D development, and Problem-Based Learning (PBL). This review confirms that the application of maritime ethnoscience is effective in improving students' conceptual understanding, scientific literacy, critical thinking skills, and awareness of the marine environment. However, the limited concentration of research on a single educational level suggests opportunities for further study at the elementary, high school, and tertiary levels. These findings emphasize the urgency of integrating maritime local wisdom into science learning, not only to strengthen cultural identity but also to equip students with 21st-century competencies.
