Abstract

Digital infographics can be an alternative visual learning media that can be used both inside and outside the classroom. Content related to bacteria in relevant learning media is very important, as bacteria can be found almost everywhere, including on the exoskeletons of houseflies. Therefore, the aim of this study is to develop a digital infographic based on the identification of bacteria on the exoskeletons of houseflies using the ADDIE development model. Product validation was carried out by 3 experts, and implementation was conducted with 32 tenth-grade students at SMAN 20 in Gowa Regency. This digital Eubacteria infographic is a visual representation of research conducted in the FMIPA UNM laboratory. It illustrates six different types of bacteria identified from the exoskeleton of houseflies, complete with microscopic images and a brief description of each bacterium's characteristics. The infographic is packaged as an application accessible via Android smartphones. The results of the study show that the digital infographic was rated as very valid with an average score of 94%, very practical with an average score of 96%, and highly effective with an N-gain value of 0.8. This study indicates that the use of contextual learning media can improve students' learning outcomes.

Abstract

The housefly (Musca domestica) is a vector that can spread bacteria through its body organs. This study aims to identify the bacteria on the exoskeleton of houseflies. The samples were collected from boarding houses, Biology department and postgraduate program of Universitas Negeri Makassar using insect nets. Morphological observations were conducted on selective media (EMBA, MSA, and TCBSA), followed by Gram staining and biochemical tests. The results revealed six types of bacteria: Enterobacter sp., Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, Vibrio cho­­lerae, and Vibrio parahaemolyticus. Escherichia coli was found on houseflies collected from boarding houses. Staphylococcus aureus, Staphylococcus epidermidis, and Escherichia coli were identified on houseflies from the postgraduate campus. Meanwhile, Enterobacter sp., Staphylococcus aureus, Vibrio cholerae, and Vibrio parahaemolyticus were found on houseflies from the Biology department campus. These findings indicate that houseflies from the Biology department campus harbored a greater quantity and diversity of bacteria compared to samples from other locations.
