Abstract

This study aims to measure and analyze the level of STEM literacy among prospective physics educators using Rasch measurement theory. A quantitative approach with a descriptive design was employed. The research instrument consisted of a STEM literacy test comprising multiple-choice questions and essays, and the data were analyzed using Winstep software version 5.7.1 to assess the validity and reliability of the measurement instrument. The results reveal that only a small number of prospective physics educators exhibit very high STEM literacy, while the majority demonstrate moderate to low levels of competencies and attitudes toward STEM literacy. The measurement instrument was confirmed to be valid and reliable according to Rasch parameters. These findings highlight the need for targeted interventions to enhance digital literacy, multidisciplinary skills, technology integration, and scientific competence among aspiring educators. Educational institutions are thereby urged to better prepare future educators to teach and promote STEM literacy effectively among students.

Abstract

Salmonella spp. are Gram-negative rod-shaped bacteria commonly found in the gastrointestinal tract of humans and animals and are recognized as one of the major causes of foodborne diseases. This study aimed to identify the presence of Salmonella spp. in gado-gado sold in the canteens of Tadulako University. This research employed a descriptive exploratory laboratory design. Samples were collected from five different canteens using a random sampling technique. Microbiological analyses were conducted through presumptive and confirmatory tests using the Most Probable Number (MPN) method, Total Plate Count (TPC), Gram staining, cultivation on selective Salmonella–Shigella Agar (SSA), and biochemical testing using Triple Sugar Iron Agar (TSIA). The MPN results showed an average value of 4,900 MPN/mL of sample, while the TPC reached 35,800/ml sample. These values indicate that the food product does not meet the microbiological safety standards established by the Indonesian Ministry of Health, as the TPC exceeds the maximum permissible limit of 104 CFU/mL.

Abstract

Escherichia coli is a Gram-negative bacterium from the family Enterobacteriaceae found in the human body and is used as an indicator of hygiene in water, food, or beverages. The purpose of this study was to identify the presence of E. coli in ice dawet sold in the Palu City area. This study used a descriptive-exploratory design with the Most Probable Number (MPN) method, Total Plate Count (TPC), and biochemical testing using Triple Sugar Iron Agar (TSIA) medium. Samples were collected from five locations in the Palu City area using simple random sampling. Based on the results, the Most Probable Number (MPN) test produced an average value of 18.700 MPN/mL of sample, while the Total Plate Count (TPC) test showed an average value of 26.800 CFU/mL of sample, indicating that the samples did not meet the standards set by the Indonesian National Standard (SNI) under the Ministry of Health, which states that the maximum allowable microbial contamination in beverages is 0/100 mL. Confirmatory tests on Eosin Methylene Blue Agar showed colony growth with a metallic green sheen and reddish coloration, characteristic of Gram-negative bacilli. The results of the Triple Sugar Iron Agar biochemical test were positive, indicating biochemical characteristics consistent with E. coli. Therefore, the findings confirm the presence of E. coli in the analyzed samples.

Abstract

Butterflies are a group of insects belonging to the order Lepidoptera, commonly known as scale-winged insects. This study examines the kinship relationships of butterfly species (Lepidoptera) based on morphological and morphometric characters in Malonas Village, Dampelas District, Central Sulawesi, an area that has not been previously documented. The objectives of this study were to identify butterfly characters through morphological and morphometric analyses and to construct kinship patterns that reflect the level of phylogenetic similarity among butterfly species. The research was conducted using a descriptive exploratory method. Sampling was carried out across all areas of Malonas Village, including residential areas, rivers, forests, and plantations, using a roaming survey method with free collection techniques, resulting in 10 butterfly species with a total of 30 individuals. Morphological and morphometric analyses included measurements of wing dimensions and major body parts. Data were analyzed using Principal Component Analysis (PCA) and the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) to determine kinship patterns. The UPGMA analysis showed that all species had a relatively high level of similarity, with a similarity value of approximately 0.78, indicating close relationships among species. PCA results revealed that two principal components (PC1 and PC2) explained 67.0% of the total morphological variation, accounting for 45.3% and 21.7%, respectively. Loading plots indicated that morphometric characters related to wing size and proportions were the main contributors to the formation of the principal components. Biplot graphs demonstrated species grouping based on similarities in morphological and morphometric characters, as well as positive correlations among variables within the same quadrant. The results of this study confirm that wing morphometric characters play an important role in explaining morphological variation and phylogenetic relationships of butterflies in Malonas Village.

Abstract

This research investigated the impact of the project-based learning (PjBL) model on the social-emotional skills. A quantitative approach with a quasi-experimental pretest-posttest control group design was utilized. The study population included all grade eight students at SMP Negeri 4 Palu during the 2025/2026 academic year. Cluster random sampling was used to select the sample, resulting in two groups: Class VIII-A (experimental group, n=27), where the PjBL model was applied, and Class VIII-B (control group, n=30), which received traditional instruction. Social-emotional skills were measured using a questionnaire that assessed the five key CASEL competencies and demonstrated high reliability (α = 0.87). Data analysis involved the Shapiro-Wilk test for normality, Levene’s test for homogeneity, and the Mann-Whitney U test for hypothesis testing, as the data did not meet normality and homogeneity assumptions. The findings revealed a Mann-Whitney p-value of 1.000 (p > 0.05), leading to the acceptance of the null hypothesis. Therefore, it was concluded that the PjBl model did not significantly affect students’ social-emotional skills.
