Abstract

This study focuses on the development of game-based learning instruments using the Baamboozle educational game for teaching digestive system material to eleventh-grade students. The need for this study arose from observations and interviews conducted with biology teachers at Hang Tuah Belawan Private High School, which revealed that the traditional teaching methods currently employed are ineffective in enhancing student interest and comprehension of complex digestive system material. The research methodology used in this study is the Four-D development model (Define, Design, Develop, Disseminate), which falls under the umbrella of development research or research and development (R&D). Data were collected through interview sheets, expert validation sheets, questionnaires for students and teachers regarding the use of learning instruments, as well as pretest and posttest sheets to evaluate effectiveness. Data analysis was conducted using the Likert scale, and the results were categorized based on the scale's interpretation criteria to conclude the validity, practicality, and effectiveness of the instruments. The findings indicate that the game-based learning instruments developed using Baamboozle games are highly valid, practical, and effective. This study makes a valuable contribution to the advancement of innovative teaching methods that combine educational game technology with complex biological concepts. The implications of this study are significant for future research and practice in educational technology, particularly in terms of enhancing student engagement, promoting the creation of interactive game-based learning content for various subjects, and exploring the long-term effectiveness of game-based learning in science education at the secondary level.

Abstract

The comprehension of concepts is crucial in educational activities and serves as the basis for achieving learning outcomes. However, students often encounter difficulties when it comes to understanding biological concepts, especially those related to the nervous system. This study aims to evaluate the impact of using the Problem-Based Learning model, with the support of the Kahoot application, on students' understanding of concepts related to the nervous system. The research design employed a Quasi Experiment approach, utilizing a Two Group Pretest and Posttest Design. Cluster random sampling was used to select the participants. A 20-question multiple-choice test was employed as the research instrument to measure conceptual understanding. Descriptive analysis techniques, including the calculation of mean, median, mode, and standard deviation, were employed for data analysis. Prior to hypothesis testing, normality and homogeneity tests were conducted to ensure data validity. An independent t-test was utilized for hypothesis testing. The descriptive analysis demonstrated that the average posttest score in the experimental group was 81.09, compared to 54.53 in the control group, indicating higher scores in the experimental group. The results of the t-test (2-tailed) yielded a significant value of 0.000 < 0.05, leading to the rejection of the null hypothesis (Ho) and accepting the alternative hypothesis (Ha). This suggests that the Problem-Based Learning model, in conjunction with the Kahoot application, has a positive impact on students' understanding of concepts.

Abstract

Nutrient Agar (NA) is a growth medium for heterotrophic microorganisms made from meat extract, peptone and agar, but commercially it is relatively expensive. As an alternative, researchers innovated using white sweet potatoes (Ipomoea batatas) which are rich in carbohydrates, protein, fat and natural fiber as a growth medium for Escherichia coli bacteria. The aim of this research is to examine the use of white sweet potato flour as a growth medium for Escherichia coli bacteria, and compare it with a medium that is added with meat broth. This research used the experimental research method twice with three repetitions of sweet potato flour, namely 10gr (w/v), 15gr (w/v), 20gr (w/v) and NA control. After conducting research on white sweet potato flour, it was found that the water content test results met the standards of around 8.56–9.66%. The panelists' organoleptic test stated that white sweet potato flour had a smooth texture, yellowish white color, slightly sweet aroma. The solubility test proved that white sweet potato flour does not dissolve in water, and the pH test showed a value of 6.8, the percentage of carbohydrates contained was 74.32%, and protein 1.36%. The results obtained by the number of bacterial colonies with the best treatment without broth were F3 (20 gr white sweet potato flour) 25.5 x 106 CFU and the best treatment with the addition of broth was F2 (sweet potato flour + 15 gr broth) 28.7 x 106 while the NA control showed results of 25.6 x 106 CFU. It can be concluded that white sweet potato flour meets all test standards so that it can be used as an alternative growth medium for bacteria, especially Escherichia coli.

This study aimed to determine the antimicrobial activity of herbal toothpaste formulations containing betel leaf (Piper betle L.) extract against Streptococcus mutans and to evaluate the physical characteristics of the resulting preparations. The research employed a laboratory experimental design with variations in betel leaf extract concentrations of 5%, 10%, and 15%, each conducted in four replicates. The analyses included phytochemical screening, antimicrobial activity testing using the disc diffusion method, and evaluation of the toothpaste preparations, including pH measurement, organoleptic assessment, homogeneity testing, foam formation analysis, and viscosity determination. The results of the phytochemical screening indicated that the betel leaf extract positively contained triterpenoids, flavonoids, saponins, phenolic compounds, and alkaloids. The antimicrobial activity test demonstrated that the betel leaf extract produced average inhibition zones of 16.4 mm, 22.7 mm, and 25.6 mm at concentrations of 5%, 10%, and 15%, respectively. The evaluation of the toothpaste formulations showed pH values ranging from 8.04 to 8.42, which fall within the Indonesian National Standard (SNI) range of 4.5–10.5. The preparations exhibited a semi-solid and homogeneous texture, with the highest foam height of 20.6 mm observed at the 15% extract concentration, and viscosity values within the required acceptable range. In conclusion, the herbal toothpaste formulation containing betel leaf extract demonstrated strong antimicrobial activity against Streptococcus mutans and met the required physical parameters for toothpaste preparations. Therefore, it has potential to be developed as an alternative herbal toothpaste based on traditional natural ingredients suitable for oral health applications.
