Abstract

Science education in the digital era continues to face challenges in optimally developing students’ science process skills and information technology competencies. The lack of instructional models that effectively connect theoretical concepts to real-world contexts remains a barrier to achieving 21st-century competencies. This study aims to analyze the effectiveness of implementing the Case Based Learning (CBL) model in integrating students’ science process skills and information technology capabilities. This research employed a quantitative approach with a quasi-experimental design. The study involved 50 tenth-grade students divided into two groups: an experimental group and a control group. Data were collected using a science process skills test and an observation sheet to assess information technology skills. Data analysis was conducted using an independent sample t-test to determine significant differences between the two groups. The results revealed an increase in the average scores for both science process skills and information technology abilities. This improvement indicates that the CBL model encourages students to engage more actively, think critically, and relate learning to real-life situations. The findings conclude that the CBL model is effective in enhancing students’ science process skills and information technology competence. The implication is that CBL can be recommended as an innovative instructional strategy for science education that is contextual and aligned with the demands of the 21st century.

Abstract

Penelitian ini bertujuan mengamati stabilitas ekspresi protein AdhF36 Salmonella typhi pada perlakuan osmolaritas dan pH dengan metodeeksperimen laboratorium-eksploratif. Hasil penelitian ini menunjukkan perbedaan ekspresi protein AdhF36 Salmonella typhi pada perlakuan osmolaritas dengan pH. Hasil SDS-PAGE menunjukkan bahwa pita protein AdhF36 tetap terekspresi pada perlakuan osmolaritas 50-350 mM, sebaliknya pita protein ini tidak terdeteksi pada perlakuan pH 4,5-6,0. Hal ini didukung oleh hasil uji Western Blot yang berhasil mendeteksi protein AdhF36 hanya pada perlakuan osmolaritas. Hasil ini membuktikan bahwa Salmonella typhi lebih toleran terhadap perubahan osmolaritas dibandingkan dengan pH.

Abstract

This study aims to analyze the phylogenetic relationships among six species of fiddler crabs (Uca spp.) found in Lalombi Village, Banawa Selatan Subdistrict, Donggala Regency, based on morphological characters. A descriptive-exploratory approach was employed, with purposive sampling to select representative specimens. Eighteen morphometric characters were measured from three individuals of each species: U. triangularis, U. perplexa, U. dussumieri, U. annulipes, U. tetragonon, and U. bellator. Data were analyzed using Principal Component Analysis (PCA) and UPGMA clustering with the aid of PAST software version 4.03. The PCA results revealed that carapace length (CL), anterior carapace width (ACW), and posterior carapace width (PCW) contributed significantly to total morphological variation. Cluster analysis indicated a close phylogenetic relationship between U. tetragonon and U. triangularis, as well as between U. perplexa and U. bellator. U. annulipes appeared intermediate between the two groups, suggesting a moderate level of relatedness. In contrast, U. dussumieri formed a distinct branch, likely due to its markedly larger body size compared to the other species. These findings affirm that morphometric characters are valuable in elucidating phylogenetic relationships within the genus Uca and support taxonomy based on morphological traits.

The research method used is the true experimental method (Experimental Research) using a completely randomized design (CRD). The number of samples used was 24 mice consisting of 6 groups and 5 replications. The normal control group (KO) was only fed and watered ad libitum, the positive control group (K+), negative control (K-) and the PI, PII, PIII treatment groups were induced with LDL for 17 days. The positive control group (K+) was given simvastatin 0.026 mg/20 BW. The normal control group (KO) and the negative control group (K-) were fed and watered ad libitum, the PI, PII, PIll treatments were induced with red coconut tembuluk extract with different concentrations. Treatment group I (PI) was induced with a concentration of 40% red coconut tembuluk extract, treatment group II (PII) was induced with a concentration of 60% red coconut tembuluk extract, and treatment group III (PIII) was induced with a concentration of 80% red coconut tembuluk extract. The observation data were analyzed using the One-Way ANOVA test. The results of the study showed that the administration of red coconut turmeric extract had an effect on reducing blood cholesterol levels in mice induced by LDL (pork fat). The red coconut turmeric extract that was effective in reducing blood cholesterol levels was a concentration of 40% (PI) where the average result of blood cholesterol level measurements was 118.4 mg/dl.

Abstract

This study aims to analyze the relationship between diet and physical activity with the nutritional status of students of SMP Negeri 19 Palu. This study used a cross sectional design with a quantitative approach and analytic observational type. The subjects were 77 students of class VIII (aged 13-15 years) who were selected using simple random sampling technique. Data were collected using FFQ (Food frequency Questionnaire) to assess diet and APARQ (Adolescent physical Activity Recall Questionnaire) for physical activity, both validated instruments from previous studies. As well as anthropometric measurements (height and weight) using the Body Mass Index (BMI) to determine nutritional status. The results of the analysis using the chi-square test showed that there was a significant relationship between diet and nutritional status (χ²(3) = 8.772; p = 0.032), and between physical activity and nutritional status (χ²(4) = 9.919; p = 0.042) Respondents with a good diet and moderate to vigorous physical activity tended to have normal nutritional status, while poor diet and light physical activity were more common among students with abnormal nutritional status. These findings suggest that diet and physical activity play an important role in determining the nutritional status of adolescents. The implications of this study emphasize the importance of educational intervention programs in the school environment to support healthy lifestyles and prevent nutritional problems among students.

Abstract

This study aims to identify Bacillus sp. in cassava tapai fermentation that has potential as a probiotic ingredient. The type of research used is descriptive exploratory using the Standard Plate Count (SPC) method, Gram staining, and biochemical testing with the Microbant System 12B. Cassava tapai samples were obtained by fermenting them for 5 days. Fermentation of cassava tapai was carried out in the Biology Education Laboratory. The results of the study showed that (1) The Standard Plate Count test yielded the highest value on the 4th day of observation at 231x10-2 CFU/ml, while the lowest value was observed on the 1st day at 162x10-2 CFU/ml. (2) Gram staining of the bacterial isolates revealed Gram-positive rod-shaped morphology. (3) Biochemical testing using the Microbant System 12B showed the ability to ferment several types of carbohydrates such as sorbitol, sucrose, lactose, arabinose, adonitol, and salicin, but it cannot ferment inositol, malonate, rhamnose, raffinose, and arginine. Thus, it can be concluded that the bacteria identified from cassava tapai fermentation can ferment in accordance with the physiological capabilities of Bacillus sp.
