Abstract

Science learning is closely linked to students' scientific writing skills. While science education imparts scientific concepts and theories, scientific writing enables students to structure and express their understanding of these concepts and theories. Despite this, scientific writing skills among junior high school students tend to be in the low category. This study aimed to investigate the impact of using student worksheets based on question prompt scaffolding on the scientific writing skills of junior high school students. The research employed a quasi-experimental design with a post-test only control group. Data were collected using tests, with essay tests assessing scientific writing skills across various indicators such as clarification, observation, measurement, claims, causation, argumentation, and generalization. The results from an independent sample t-test indicated a significance value of p Sig. (2-tailed) of 0.028, which is less than 0.05, suggesting a significant difference in the average scientific writing scores between the experimental and control groups. Thus, it can be concluded that student worksheets based on question prompt scaffolding significantly enhance the scientific writing skills of junior high school students in science learning.

Abstract

Currently, waste processing is a problem because it is not yet optimal. The high content of nitrates and nitrites results in environmental pollution which can cause losses because it affects health and biodiversity. One effort to control environmental pollution is phytoremediation using calla lily (Zantedeschia aethiopica) to remediate nitrate and nitrite levels that do not comply with quality standards so that pollution can be minimized. This research aims to determine the effectiveness of calla lily as a phytoremediation agent for landfill leachate nitrate and nitrite. This experimental research method uses a Completely Randomized Design (CRD) which consists of three treatment levels, namely variations in calla lily biomass of 0 grams, 200 grams, and 400 grams with 3 repetitions, and measurements of nitrate and nitrite levels are carried out on day 1, day 2. 3, and 7. The results showed that the most optimal percentage reduction in leachate nitrate levels occurred in the P1 on the day 7, namely 45%, while the most optimal percentage reduction in leachate nitrite levels occurred in the P1 on the day 7, it was 53%. The final nitrate content after the research was in accordance with the quality standards of PP RI No.22 of 2021, while the leachate nitrite content after treatment still exceeded the quality standards of PP RI No.22 of 2021. Calla lily has the potential to reduce nitrate and nitrite levels due to landfill leachate pollution.
