Abstract

This study aims to describe the influence of parental income on students' learning motivation. This study uses a descriptive qualitative approach. The subjects of this study consisted of 30 students in grade VII. The results showed that the majority of students came from families with low incomes, and this had an impact on students' low learning motivation. The level of parental income influenced the learning motivation of students in the subject of science (Biology) in grade VII at SMP Negeri 20 Sigi. The researcher found several students whose parents had low incomes so that it influenced the students' learning motivation, from the 30 samples that the researcher used, there were 26 students with low incomes with incomes <Rp.500,000 and those with high incomes were 4 students with incomes of Rp. 1,000,000 - Rp. 1,999,999. The average student learning motivation only reached 36%, which is included in the very low category. Internal factors (31%) and external factors (42%) both play a role in decreasing students' learning motivation. Interventions such as scholarships and support from parents and schools are needed to increase students' enthusiasm for learning. Thus, it can be concluded that the learning motivation of class VII students at SMP Negeri 20 Sigi is very low.

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

Education plays a critical role in shaping the cognitive, affective, and psychomotor development of students. In the 21st century, students are expected not only to acquire knowledge but also to develop the ability to think critically, solve problems, and apply concepts in real-life situations. For this reason, this study aims to determine the effect of applying the problem-based learning model assisted by mind mapping on student learning outcomes in ecosystem lesson. This research employed a quasi-experimental approach using the Pretest-Posttest Non-Equivalent Control Group Design, involving both control and experimental classes. The study population included all tenth-grade students at SMA Negeri 1 Biau. Through purposive sampling, four classes were selected, totaling 121 students. Learning outcomes data were collected using a test instrument comprising 30 multiple-choice questions. The data were analyzed using the Mann-Whitney statistical test at a significance level of 0.05. The analysis results revealed that the use of the problem-based learning model combined with mind mapping had a statistically significant impact on student learning outcomes, with a p-value less than 0.05 (0.000 < 0.05). Therefore, it can be concluded that the integration of mind mapping within the problem-based learning model has a positive influence on learning achievement. These findings suggest that this instructional approach is effective and can be implemented in lessons focused on ecosystem.

Abstract

The growing demand for functional foods has encouraged the development of dairy products enriched with natural bioactive ingredients to improve nutritional value and health benefits. This study aimed to analyze the nutritional composition and antioxidant activity of yogurt enriched with butterfly pea (Clitoria ternatea L.) extract. Yogurt was prepared from fresh goat milk with varying concentrations of butterfly pea extract and evaluated for protein, fat, carbohydrate, moisture, ash, vitamin C contents, antioxidant activity, and sensory acceptance. Proximate analysis, UV–Vis spectrophotometry, and the DPPH method were used for chemical determinations, while a hedonic test assessed color, taste, aroma, and texture. Results showed that increasing butterfly pea extract significantly decreased protein and fat contents but increased vitamin C and antioxidant activity, with the highest values observed in yogurt containing 60% extract and 4% formulation (N60K2). Moisture and ash contents were not significantly affected. Sensory evaluation indicated that yogurt with 60% extract and 2% formulation (N60K1) was preferred regarding color, taste, aroma, and texture. Considering compliance with the Indonesian National Standard (SNI) and consumer acceptance, N60K1 was the optimal formulation. The findings suggest that butterfly pea extract can enhance the functional properties of yogurt, particularly its antioxidant potential, while maintaining acceptable sensory quality. This provides insights for developing functional dairy products with natural plant-based bioactives.

Abstract

Honey is a valuable natural product with nutritional, medicinal, and economic importance, but its high commercial value makes it prone to adulteration, which threatens consumer trust and product quality. This study aimed to evaluate the effectiveness of simple purity tests in identifying adulteration in honey samples collected from several regions in Central Sulawesi Province. A total of 12 honey samples from different bee species and floral sources were analyzed using seven tests, namely solubility, cloudiness and foam, heating, hexagonal pattern, seepage, raw fish, and onion tests. The results showed that most tests successfully distinguished pure honey from adulterated samples. Specifically, the solubility, cloudiness and foam tests, as well as heating, and raw fish tests indicated that 66.67% of the samples were pure, while the hexagonal pattern, seepage, and onion tests confirmed purity in all samples (100%). These findings demonstrate that simple, low-cost methods can provide reliable initial screening of honey purity and are suitable for routine use in local communities where advanced laboratory facilities are limited. The application of these tests is expected to support honey quality assurance, protect consumer trust, and promote the sustainable development of the beekeeping industry in Central Sulawesi.

Abstract

Bats play an important role in ecosystems as pollinators, seed dispersers, and insect pestcontrollers. Indonesia has the highest bat diversity in Southeast Asia, with Sulawesi as a globalendemicity hotspot. However, data from Central Sulawesi remain limited, particularly amid threats ofhabitat degradation and hunting toward bats. This study aims to assess the diversity and habitatpreferences of Yangochiroptera and Yinpterochiroptera in Bualemo sub-district, Central Sulawesi. Datawere collected for 31 nights in June and July 2024 using mist nets and harp traps across plantationsnear cave, plantations, secondary forests, and rivers. A total of 474 individuals from 5 families and 23species were identified. Yangochiroptera consisted of 113 individuals from 4 families and 13 species.Meanwhile, Yinpterochiroptera consisted of 361 individuals from one family and 10 species, withCynopterus luzoniensis and Rousettus amplexicaudatus as the most frequently found species. TheShannon-Wiener diversity index (H' = 1.534-2.210), indicating moderate diversity, while the evennessindex (E = 0.489-0.705), suggesting more balanced distribution in vegetated habitats.Yinpterochiroptera were mainly found in plantations rich in food sources, such as Ficus trees, whileDobsonia exoleta and Harpyionycteris celebensis were restricted to secondary forests. Yangochiropteradisplayed distinct habitat preferences. Rhinolophus sp.a dominated plantations near cave, whereasRhinolophus sp.b occurred only in secondary forests. These preferences were influenced by foodavailability, vegetation structure, and environmental conditions such as rainfall and moon phase. Thesefindings emphasize the importance of conserving various habitat types to maintain the diversity andstability of bat populations, while raising public awareness of their ecological role.

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.
