Abstract

Greening is one of the efforts to create environmental clarity in flood-prone areas. These activities can support the beauty and environmental sustainability. One of the main factors causing soil damage is the flow of water onto the earth's surface when it rains. Floods are caused by heavy rains that result in excess water. Trees play an important role in flood protection. This is because trees can store water that seeps into the ground. Trees have many benefits in life such as preventing floods, cleaning the air and being a source of food for other organisms. There are flood-prone areas around Sahilan Darussalam Village which have recently been inundated with water such as river banks, village offices and their surroundings. In the Sahilan Darussalam Village area there are areas that lack greenery, especially around schools, so to improve environmental sustainability and prevent flooding, the greening was carried out by KUKERTA students at the University of Riau based on research results obtained so as to create an area around the village that is anti-disaster.

Abstract

Misconceptions about buffer solutions are an important issue in chemistry learning because they can affect students’ understanding of advanced concepts related to acid–base equilibrium. This study aims to identify students’ misconceptions about Grade XI buffer solution material at SMA Negeri 15 Pekanbaru. This study used a descriptive analytical method with a quantitative approach. The research sample consisted of 122 Grade XII students at SMA Negeri 15 Pekanbaru who had studied buffer solution material. Data were collected using a five-tier diagnostic test instrument consisting of 20 items as well as interviews using a purposive sampling technique. The results showed that students’ misconceptions about buffer solution material as a whole reached 26.71% and fell into the low category. Based on the concepts analyzed, misconceptions about the definition of buffer solutions reached 27.14%, the properties of buffer solutions 30.60%, the working principles of buffer solutions 16.39%, differences among buffer solutions 25.41%, pH calculations for buffer solutions 30.21%, the role of buffer solutions in the human body 25.00%, and methods of preparing buffer solutions 32.24%. The identified sources of misconceptions came from books at 12.581%, teachers 8.45%, personal reasoning 65.19%, peers 10.28%, and the internet 3.82%. The conclusion of this study affirms that students’ misconceptions about buffer solution material are still found in several concepts, especially in preparation methods, properties, and pH calculations of buffer solutions. These findings provide a practical contribution for chemistry teachers in designing more appropriate learning strategies and diagnostic evaluations to reduce misconceptions about buffer solution material.
