Abstract

The use of Cr (Chromium) in industry and daily life produces toxic waste harmful to humans and the environment. This study aims to evaluate the effectiveness of activated carbon from corn cobs as an adsorbent for Cr(VI) heavy metal. Corn cobs, which contain 40–44% cellulose, were carbonized at 500°C using 6% sodium carbonate and characterized with an IR spectrophotometer. Adsorption tests were conducted by varying pH and contact time to determine optimal conditions. FTIR results revealed functional groups such as C≡C stretch, C=C=C stretch, and C–O bend. After activation, O–H groups appeared, indicating the presence of aromatic compounds, which are typical in activated carbon. The optimum pH for Cr(VI) adsorption was pH 4, with an adsorption rate of 65.35%. The optimum contact time was 60 minutes, resulting in 3.2% Cr(VI) adsorbed and a maximum adsorption capacity of 0.089 mg/g. In conclusion, corn cobs are a promising, eco-friendly, and effective natural material for adsorbing Cr(VI) heavy metal ions.

Abstract

Coal is an organic mineral from ancient plant remains that settles and goes through physical or chemical processes over a period of up to millions of years. Coal is used as a source of steam-powered electrical energy through combustion which produces fly ash waste. fly ash contains various chemical materials such as SiO2; Al2O3; Fe2O3. The potential chemical content makes fly ash which can be used as an adsorbent for heavy metals and dyes by forming silica xerogel. To increase the silica oxide content in fly ash, a washing process is carried out with various solvents. Research on the adsorption of methylene blue dye using silica xerogel from fly ash with variations in contact time. The results showed that silica xerogel from fly ash was able to adsorb methylene blue dye at a contact time of 90 minutes. Adsorption kinetics follows a pseudo second order model with an R2 value that is better than pseudo first order. It can be seen that the R2 value respectively shows a linear regression of 0.703 for pseudo first order and 1 for pseudo second order.

Abstract

This study aims to determine how nano chitosan is produced through the ionic gelation method. The process of making nano chitosan is carried out using variations in chitosan concentrations of 1%, 5%, and 10%, and using a magnetic stirrer. Morphological tests were carried out using Scanning Electron Microscopy (SEM) to observe the shape and size of the particles formed. The addition of TPP (Trisodium Tripolyphosphate) as a crosslinker and certain surfactants are used to increase particle stability. Treatment for ±2 hours showed optimal results in terms of a more homogeneous particle size distribution. Based on the results of SEM observations, it is known that increasing the concentration and time settings and the use of appropriate surfactants can reduce wrinkles in nano chitosan particles. The particle size obtained is in the range of 278–350 nm. Thus, the ionic gelation method has proven effective in producing uniform nano chitosan and has good morphology for further applications.

Abstract

Conceptual understanding is an important aspect of learning biology because it reflects the extent to which students can internalize knowledge and relate it to real life. This study aims to analyse the level of understanding of the concept of biodiversity of students and identify supporting and inhibiting factors in the biology learning process. The research was conducted in class X of SMA Negeri 1 Pineleng with a descriptive qualitative approach. Data was collected through observation, written tests, questionnaires, teacher interviews, and documentation. Conceptual comprehension is measured using three main indicators: the ability to restate concepts, classify objects based on certain properties, and provide examples rather than definitions. The results showed that 87.5% of students had achieved a good level of understanding of classification indicators and giving examples, but only 50% were able to restate concepts completely. The supporting factors identified include learning motivation, parental mentoring, teacher learning strategies, and student absorption. On the other hand, barriers to understanding include lack of enthusiasm for learning, an unsupportive environment, and a lack of parental involvement. These findings confirm that the success of conceptual understanding is determined not only by cognitive aspects but also by comprehensive pedagogical and social support. This research makes an important contribution to the development of more contextual and participatory biology learning strategies, as well as opens opportunities for further research that explores the use of innovative media in strengthening conceptual understanding.

Abstract

Improving students' Biology learning outcomes is a major challenge in the learning process in high school, especially when the material taught is abstract and complex, such as the human digestive system. This study aims to analyze the effectiveness of the Problem-Based learning model assisted by mind mapping in improving the learning outcomes and activities of grade XI students of SMA Negeri 2 Tondano. This research is a Classroom Action Research conducted in two cycles, each consisting of two meetings. Each cycle involves planning, action execution, observation, and reflection activities, with data collection through observation, testing, and documentation. The results of the study showed a significant increase in learning activities and student learning outcomes. The average learning activity increased from 54.6% in the first cycle to 81% in the second cycle, while the percentage of completeness of learning outcomes increased from 59% to 88%. This increase is influenced by the active involvement of students in group discussions, visualisation of concepts through mind mapping, and the role of teachers as facilitators in problem-based learning. These findings indicate that the integration of the Problem-Based model with mind mapping is effective in building critical thinking skills, improving concept understanding, and encouraging active student participation. The implications of this study show the importance of implementing innovative learning strategies to improve the quality of Biology learning in secondary schools.
