Abstract

This study aims to determine the effect of the Problem Based Learning (PBL) model on students’ problem-solving abilities in the reaction rate material at SMA Negeri 07 Gorontalo. The research employed a quasi-experimental method with a pretest-posttest control group design. The subjects consisted of two classes: class XI1 as the experimental group (using the PBL model) and class XI2 as the control group (using conventional learning). The instrument used was an essay test based on problem-solving indicators. The results showed a significant improvement in problem-solving ability in the experimental class compared to the control class. The average posttest score of the experimental class was 74 (categorized as good), while the control class scored 52 (categorized as fair). The t-test results indicated a significant difference between the two groups (p < 0.05), suggesting that the PBL model is more effective in enhancing students' problem-solving abilities than conventional learning methods.

Abstract

Critical thinking skills are an important competency in learning biology, especially in biodiversity materials that require analysis, reasoning, and decision-making. This study aims to determine the influence of the Guided Discovery Learning learning model on the critical thinking ability of grade X students at SMA Negeri 2 Tondano. The method used was a quasi-experimental study with a pretest-posttest control group design. The sample consisted of two classes, namely the control class that was taught using the conventional model and the experimental class that received treatment with the Guided Discovery Learning model. Data were collected through pretest and posttest written tests, and analyzed using normality, homogeneity, and t-test. The results showed that there was a significant difference between the learning outcomes of students in the experimental class and the control class. The average posttest score of the experimental class was 81 higher than the control class of 63.5. In addition, the Tcal value of 4.65 is greater than the Ttable of 2.02 at a significance level of 0.05, which shows that the Guided Discovery Learning model has a positive influence on improving students' critical thinking skills. This result is also strengthened by a decrease in standard deviation which shows an equal distribution of understanding between students. This research contributes to the development of active learning strategies in biology education and suggests the application of this model to improve higher-level thinking skills. This model is also relevant applied to other topics in order to strengthen discovery-based learning and collaboration.

Abstract

Food is a basic need that must be met by every individual. In Indonesia, rice is still the main staple food, but the shift in consumption to rice and wheat which are imported foodstuffs raises concerns about food security. Therefore, the development of local food alternatives such as MOCAF (Modified Cassava Flour) flour from cassava is important. In this practicum, MOCAF flour was made through a cassava fermentation process, followed by making onion cakes using the MOCAF flour. Organoleptic tests and XRF tests were carried out to evaluate the quality of MOCAF flour. The results of the practicum showed that the substitution of MOCAF flour in making onion cakes can produce low-gluten products that have the potential to be a sustainable food alternative.

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

Sacha inchi (Plukenetia volubilis Linneo) is a plant from the Euphorbiaceae family known for its green star-shaped fruit and brown seeds. This plant has high nutritional value and significant antioxidant activity (Nuha and Sriwidodo 2022). This study aims to identify secondary metabolite compounds and determine the total phenolic content of the methanol extract of Plukenetia volubilis Linneo leaves. The samples were extracted using the maceration method, then phytochemical tests and total phenolic content analysis were carried out using the Folin-Ciocalteu method (Sari et al. 2021). The results of the phytochemical test showed that the methanol extract of sacha inchi leaves contained secondary metabolite compounds such as alkaloids, flavonoids, saponins, and tannins. The total phenolic content obtained from the extract was 19.94%, which indicates the potential for high antioxidant activity. The results of this study indicate that sacha inchi leaves have the potential to be developed as a source of natural bioactive compounds that are beneficial to health.

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.
