Abstract

Mental models in chemistry concepts are defined as student’s comprehension of three levels of chemical representations, including macroscopic, submicroscopic, and symbolic levels. This study aims to identify, review, and evaluate research concerning mental models in chemistry concepts through specific research questions. The research method used is a systematic literature review (SLR) by analyzing relevant articles from Google Scholar, Eric, Scopus, and Crosscref, focusing on publications from the the past decade (2013–2023). A total of 52 articles were obtained from the analysis based on the inclusion and exclusion criteria. The findings indicate that most studies aim to understand students' mental model profiles related to chemistry concepts. High school students are predominantly involved as research samples. The most used data collection tool is diagnostic tests. Mental models are primarily studied in physical chemistry, particularly in chemical equilibrium, adopting various theories, especially the Sendur, Toprak, and Pekmez (2010) model. Factors influencing the formation of students' mental models include internal factors such as prior knowledge, experiences, attitudes, and motivations, and external factors such as the environment, incomplete textbooks, and inappropriate teaching strategies.

Abstract

Indonesia controls 75%-80% of the world's carbon stocks, so the amount of carbon stocks must be utilized optimally. This study aims to determine carbon stocks, potential emissions, and economic value of carbon stocks in each land use. The method used is secondary data analysis and field checking. The data collected were Sentinel 2A acquisitions in 2020 and 2022, Digital Elevation Model (DEM), and land use land cover in 2020-2023. Data analysis used SNAP and ArcGIS 10.8. The tool used for data analysis is spatial analysis map algebra. The results showed mixed dryland agriculture has the most extensive carbon stock, at 2,614,178 tons/ha, with potential emissions of 9,585,320 tons/ha. The most minor carbon stock is in mining land use, which is 0 tons/ha with potential emissions of 0 tons/ha. The highest C02 value in USD is the forest land use group. In the Secondary Dryland Forest, Secondary Swamp Forest, and Plantation Forest groups, it is 17,517,400.50 USD, while the lowest is mining land use, which is 0 USD. Overall, the CO2 value of land use in the study area is 34,246,314.45 USD. Integrating remote sensing data analysis and field surveys in geospatial technology is one of the new approaches to studying carbon stocks and CO2 emissions in topsoil from various land uses.

Abstract

This study aims to determine the cultivation of sangkuriang catfish (Clarias gariepines) for 59 days. The method used in this study is observation by collecting primary data directly from the field. During the study, the highest pool water temperature was found in the second week of 29.11 oC and the lowest temperature of pool water was found in the third week of 28.22 oC. The temperature of the pool water in the morning is lower than in the afternoon. This is influenced by sunlight that directly enters the pond which results in an increase in the metabolic process of the catfish body. The pH of Sangkuriang catfish farming pond ranges from 7.8-7.25. If the highest pH value indicates that the waters are alkaline, on the contrary, if the low pH value indicates acidic, the conclusion is that the salinity treatment of the medium does not have a significant enough effect (P<0.05) on the survival rate of catfish. Sangkuriang catfish is a type of fish that is able to survive and breed in conditions where water is less oxygen and low pH levels, in the first week the oxygen degree is 1.25 and the lowest at 0.65. Catfish tend to be more active in warm water temperatures, but they can also survive in winters with lower temperatures. However, they may become less active and require extra attention to ensure the water temperature remains within limits they can tolerate.
