Abstract

Critical reasoning plays a crucial role in analyzing and evaluating available information and in formulating appropriate solutions to issues arising in communities today. This role can be enhanced through a place-based socioscientific issues (SSI) approach. This study aims to enhance prospective natural sciences teachers’ critical reasoning through a place-based SSI approach in West Kalimantan in two contexts: the use of kratom (Mitragyna speciosa Korth.) and tuak (rice wine). This study employed a quasi-experimental, non-equivalent control group pretest–posttest design and involved 64 students at Universitas Tanjungpura. Data were collected using a test comprising critical reasoning dimensions: information evaluation, complexity identification, information sources credibility assessment, and multiperspective. The profile of prospective natural sciences teachers’ critical reasoning showed improvement across all dimensions. The effectiveness of the place-based SSI approach showed a statistically significant improvement (p-value < 0.05) on the dimensions of complexity identification (large effect size), information sources credibility assessment (medium effect size), and multiperspective (medium effect size). The information evaluation dimension was insignificantly different (p-value > 0.05), despite a medium effect size. The findings show that a place-based SSI approach is effective for enhancing prospective natural sciences teachers’ critical reasoning. This study strengthens the SSI-based learning literature, develops scientifically literate citizens, and increases the quality of teacher education programs. Furthermore, this study contributes to Sustainable Development Goals (SDGs), particularly SDG 4 (Quality Education), by increasing the number of individuals with the skills necessary to navigate the ever-changing times and by enhancing the quality of prospective natural sciences teachers in West Kalimantan.

Abstract

Mandai—traditionally made from Artocarpus integer mesocarp—originates from Central, South, and East Kalimantan and has been adopted in West Kalimantan. However, data on the microbiological and nutritional properties of West Kalimantan mandai have yet to be revealed. Therefore, this study aims to analyze the microbiological and nutritional properties of mandai. Mandai samples were obtained from one traditional producer. The analysis of microbiological properties included bacterial isolation, followed by molecular identification through 16S rRNA gene sequencing and phylogenetic analysis. The analysis of nutritional properties includes the determination of proximate, crude fiber, amino acid, and essential mineral profiles. Microbiological properties showed that the mandai contains four Enterobacter species. However, no lactic acid bacteria (LAB) were detected in the samples. Meanwhile, the nutritional properties indicate a high concentration of moisture, ash, and essential minerals; low levels of total fat, protein, and carbohydrates; as well as the existence of L-serine and L-tyrosine. The total energy obtained is 15.50 kcal/100g. Therefore, it can be concluded that although mandai contains nutritional values, the presence of Enterobacter poses a food safety risk. As the first to analyze the microbiological and nutritional properties of mandai obtained from West Kalimantan, this study benefits science and society, as the unexpected finding of Enterobacter emphasizes the urgency of production process standardization. Moreover, this study correlates with Sustainable Development Goals (SDGs) 2 and 3 due to the main focus of this study, which reveals crucial information regarding the safety of consuming mandai, which can benefit health from the nutrients it contains.
