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.

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.

Abstract

This study aimed to determine the phylogenetic relationship of coral trout groupers (Plectropomus spp.) in the waters of Liang Village, Banggai Kepulauan Regency, based on morphological characters. The research employed a descriptive exploratory method with quantitative and qualitative approaches. Samples were collected using purposive sampling, obtaining 15 individuals representing five species: Plectropomus leopardus, Plectropomus oligacanthus, Plectropomus maculatus, Plectropomus areolatus, and Plectropomus leavis. Morphological observations included 25 morphometric characters, 11 meristic characters, and 4 qualitative characters. Data were analyzed using Principal Component Analysis (PCA) to identify the main morphological characters contributing to variation among species, followed by cluster analysis using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) to assess phylogenetic relationships. The results indicated that the physicochemical conditions of the waters in Liang Village were suitable to support coral trout grouper populations. PCA results showed that the first two principal components (PC1 and PC2) explained 73.31% of the total morphological variation, with interorbital length, dorsal fin base length, and body depth contributing most significantly to species differentiation. The UPGMA dendrogram revealed that Plectropomus leopardus exhibited the closest phylogenetic relationship with Plectropomus areolatus and Plectropomus oligacanthus, while Plectropomus maculatus showed the greatest morphological divergence and formed a separate cluster. These findings demonstrate that morphological characters are effective in revealing phylogenetic relationships among Plectropomus species in the studied waters.

Abstract

The rapid development of digital technology in education demands innovative learning models that combine flexibility, interactivity, and collaboration to enhance student engagement and learning outcomes. This classroom action research aimed to analyze the effectiveness of a blended learning model integrated with the cooperative Teams Games Tournament (TGT) approach in improving students’ learning outcomes and active participation in Biology subjects. The study was conducted in two cycles involving 28 students of class XI H at SMAN 4 Palu during the 2024/2025 academic year. Data were collected through observation sheets and cognitive learning tests. The results showed a significant improvement in both teacher performance and student learning outcomes. The average teacher activity increased from 78.2% (Good) to 93.7% (Very Good), while students’ classical mastery rose from 53.57% to 79%, with the N-Gain improving from “Low” (0.29) to “Moderate” (0.49). Statistical analysis using the Wilcoxon Signed-Rank test confirmed a significant difference between pre-test and post-test scores (p < 0.001), with an effect size (r = -1.000) categorized as very large. Additionally, students’ active participation increased from “Fairly Active” to “Active” in most aspects. These findings indicate that integrating blended learning with the TGT model effectively enhances both cognitive achievement and engagement in Biology learning.

Abstract

Many carbohydrates are produced from the Cassava plant (Manihot esculenta Crantz) and have an essential role for humans. Cassava is used not only as a food source but also as industrial raw material, ethanol, and animal feed. To avoid the rapid deterioration of post-harvest Cassava products, Casava is very potential to be developed into various processed products and industrial raw materials. The development of the snack or snack industry has proliferated, both in type, taste, and packaging. The results of interviews conducted by a service team with the home industry Cake group in Toaya Vunta village showed that many cassava plants still have not been used optimally. This service aims to provide training and mentoring workshops on making Cassava crackers (Cassava crackers) of various flavors to mothers of the home cake industry group in Toaya Vunta village. Through the community service program, the Toaya Vunta village home industry group can be assisted in training and workshops to manufacture more modern Cassava chips with different flavors to improve their knowledge and skills. The method in this activity is to use the method of lectures, demonstrations, discussions, practices, and observations, which are the results of the activities. This activity has three stages: material presentation, direct practical assistance in making cassava chips, and the packaging process. The results of this service can improve the knowledge and skills of the home industry group of mothers in making cassava chips with various flavors. Based on these results, it is hoped that it can improve the family economy as well as support the development of creative economy businesses and community empowerment in Toaya Vunta village
