Abstract

The integration of digital technology into education is rapidly expanding. However, the use of technology in learning is often uneven. Limited literature on Schistosomiasis among students contributes to a lack of understanding about this disease. This study aimed to develop a valid, practical, and effective e-module for identifying Schistosoma japonicum worm eggs in human feces in North Lore District, Central Sulawesi. The ADDIE model was employed for the e-module's development, which included stages of needs analysis, design, development, and evaluation. The media and material validity test yielded highly valid results. The e-module's practicality was assessed as highly practical for use in teaching. The effectiveness of the media was determined to be highly effective, with an n-gain test score of 0.76, indicating a high level of learning. Based on these findings, the e-module is deemed valid, practical, and effective for use in biology education. This study is anticipated to be a reference for future researchers developing similar products in other biology subjects.

Abstract

The Sunda pangolin, also known as Manis javanica, is a vulnerable mammal that can be found in Java, Sumatra, and Kalimantan. Unfortunately, due to hunting, poaching, land changes, and forest fires, particularly in Kalimantan, this species is now categorized as endangered on the IUCN Red List. To support conservation efforts and sustainability of the Sunda pangolin, it is crucial to gather more evidence about its ecological study and habitat. Therefore, this study aimed to determine the characteristics of the habitat and distribution of the Sunda pangolin in the Bukit Tangkiling Nature Park, Central Kalimantan. We surveyed between February and June 2022 using a Visual Encounter Survey (VES) combined with burrow count methods and camera traps. The survey included vegetation, potential nest and prey, and abiotic factors for the Sunda pangolin. We found a total of two individuals using a camera trap in plot 1 and direct observation in plot 3. Additionally, we located five potential Sunda pangolin nests. According to the distribution map, the Sunda pangolin can be found in hilly and valley areas, with an estimated population of 7.14 individuals/Ha. Vegetation analysis revealed an importance value index (IVI) of 148.84% for Acacia mangium. Based on PCA results, the abiotic factors of air and soil humidity support the existence of the Sunda pangolin and its nests. We also identified eight species of Hymenoptera and one species of Isoptera, which are potential food sources for the Sunda pangolin. Overall, this study provides essential information to support conservation efforts and sustainability of the Sunda pangolin in Kalimantan.

Abstract

Plastic is one of the main pollutants in the ocean due to its persistent nature. Plastic in waters can be broken down into pieces <5 mm in size, called microplastics, and enter the bodies of aquatic biota such as shellfish. The objectives of this research was to analyze the abundance and identify the characteristics of microplastics in blood clam and green mussel from Pasar Beringharjo, Yogyakarta City. The method in this research is to sample shellfish from Pasar Beringharjo. The shellfish samples obtained had their meat removed and soaked in 10% KOH for 3 days. The isolation results were filtered and the microplastics obtained were observed under a light microscope to determine their abundance and characteristics. The polymers that make up microplastics are analyzed by FTIR. The abundance and characteristics of microplastics between shellfish kinds were compared using the Mann Whitney test. The results showed that the abundance of microplastics in blood clam (average 839.25 ± 144.24 microplastics/individual) was higher compared to green mussel (average 703.75 ± 159.21 microplastics/individual), but not significantly different (p>0.05). The form of microplastic that dominates in both kinds of shellfish is fragments. The most common color of microplastics found in both kinds of shellfish was black and brown. The size of microplastics in both kinds of shellfish is dominated by the range 0-100 µm. FTIR results indicate the type of nylon polymer (polyamide). Microplastics in blood clam and green mussel from Pasar Beringharjo, Yogyakarta City have almost the same abundance and characteristics.

Abstract

Probiotics are living microorganisms which have beneficial effects. One of the benefits is enhancing immunity. Therefore, probiotics are often supplemented into food, medical, and aquaculture products. B. subtilis KM16 as endospore-producing bacteria have been known to increase probiotic resistance to confront the unstable conditions of the digestive tract. Spore formation of Bacillus is supported by the optimal condition of growth medium and incubation periods. The sufficient availability of carbon, nitrogen, and mineral source in the growth medium, and environmental conditions can support the formation of optimal endospores. This research aimed to determine the suitable sugar composition of a medium and optimum incubation time suitable for endospores formation of B. subtilis KM16. Glucose and maltose were utilized as a carbon source in several concentration as a growth medium for B. subtilis KM 16. The incubation time was 48 and 72 hours. The viable number of vegetative cells was not significantly different for the type of sugar and incubation periods. Based on the glucose concentration, 0.2% glucose exhibited the uppermost number of cells, while 1% glucose concentration caused the decrease of vegetative cells. In this study, 0.2% glucose with 48 hours incubation period showed the highest percentage of sporulation frequencies, up to 48%, but it was not significantly different from the other glucose concentration. The medium that contains 0.2% glucose with 48 hours incubation period is the best medium for the utilization of B. subtilis KM16 cells and spores as probiotic candidates.

Abstract

Habits of mind is one of the dimensions of long-term learning that allow productive actions to occur and can produce positive student character in solving problems in their lives. The importance of habits of mind is in contrast to the ability of habits of mind of students in one of the high schools in Bandung City which is still low. Based on this, the researcher aims to analyze the biology learning process carried out by teachers to further understand the factors that influence students' habits of mind. The method used in this research is quantitative descriptive. The sample was chosen using convenience sampling, so that 34 samples were obtained from class X students and biology teacher at one of the state high schools in Bandung City. The research results show that the low level of students' habits of mind is because teacher has not implemented how to develop students' habits of mind in classroom learning. Differentiated learning, student centers, reflection activities, and learning independence in using resources are the next researchers' recommendations for interventions to improve students' habits of mind.

Abstract

This study explores the integration of three innovative learning approaches, namely Problem-Based Learning (PBL), Teaching at the Right Level (TaRL), and Culturally Responsive Teaching (CRT), in improving learning outcomes in Science in grade 8. In education as a pillar of state-building and character-building, these approaches provide a foundation for effective and meaningful learning. PBL places students as agents of learning by providing real challenges, while TaRL adapts learning to students' ability levels, and CRT utilizes students' cultures and experiences for more meaningful learning. An experiment at Junior High School 25 Semarang showed significant improvements in student learning outcomes, learning motivation, and student character. Quantitative analysis confirmed the improvement in learning outcomes, while interviews revealed positive changes in students' learning motivation and character. However, challenges in learning implementation were also shown, including the need to increase diversity in teaching methods, pay attention to students' needs, and create an interactive learning environment. This study shows that the integration of PBL, TaRL, and CRT is promising in improving science learning outcomes and shaping students' characters. However, continuous efforts to improve the quality of learning and the role of teachers are essential to achieving optimal learning goals and creating a bright and characterful generation.
