Abstract

This research aimed to isolate and identify the types of bacteria present on the surface of biology education students' mobile phone screens. This was an exploratory study using a bacterial isolation method.Bacteria found on the mobile phone screens were cultivated using MacConkey agar, a selective medium specifically designed to detect and identify Gram-negative bacteria, particularly Enterobacteriaceae like Escherichia coli. The accuracy of the Escherichia coli data from the phone screen samples, after processing with the Microbact System, was 96.39%.Malt Extract Agar (MEA) was also used as a selective medium to detect and identify Gram-positive fungi, such as Candida albicans.Based on these findings, the developed module was deemed highly feasible. A learning medium is considered highly feasible for use if it achieves a presentation rate between 60-100%. With an average score of 82.39%, the module meets this criterion and can be effectively used in learning.

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 improve the critical thinking skills of class X MIA 1 students at SMAN 2 Sirenja through the implementation of the Project Based Learning (PjBL) model in Biology subjects. This research used a Classroom Action Research (CAR) approach, conducted in two cycles, each consisting of planning, action, observation, and reflection stages. Data were collected through teacher and student activity observations, as well as critical thinking skill tests. Research data were analyzed using descriptive statistics. The results showed a significant improvement from cycle I to cycle II. Classical completeness increased from 41.17% to 88.2%, while classical absorption increased from 64.26% to 80.8%. Both teacher and student activities improved, reflecting higher engagement in the learning process. In addition, critical thinking indicators such as analysis, evaluation, and problem-solving showed positive development.Thus, the implementation of the Project Based Learning model proved effective in enhancing students' critical thinking skills and in creating a more active, collaborative, and contextual learning environment.

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 aims to improve student learning outcomes in Biology through the implementation of Project Based Learning (PBL) in class XIA at SMAN I Bunobogu. The method used in this study is a Classroom Action Research (CAR) design consisting of four stages: planning, implementation, teacher observation, and student observation. The subjects of this study were 28 students in class XIA. The data collection instruments used in this study included teacher observation sheets, student observation sheets, and post-tests. The results of this study indicate that the project-based learning model in Biology has significantly improved student learning outcomes. This is demonstrated by the data analysis conducted during the first cycle, which showed a student learning outcome rate of 71%, while the second cycle saw an increase to 93%. Based on the results of this study, it can be concluded that the implementation of the Project-Based Learning model successfully improved student learning outcomes.

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.
