Abstract

Cyanobacteria exhibit a wide range of fatty acid profiles, which vary significantly among different species and strains. This study aimed to characterize the fatty acid profile of cyanobacteria isolated from Cagar Alam Pulau Dua (CPAD) Sanctuary in Serang, Banten. The isolates, previously identified as Lyngbya sp. and Aphanothece sp., were grown on ASN-III medium and harvested at the beginning of the stationary phase. Cyanobacterial lipids were extracted using two methods, i.e., the Bligh and Dyer method and the Soxhlet method. The composition of cyanobacterial fatty acid was analyzed using gas-liquid chromatography (GLC). The result showed that Lyngbya and Aphanothece have a higher saturated fatty acid composition than unsaturated fatty acid. Lyngbya contains 33.154% SFAs and 7.304% UFAs, while Aphanothece contains 55.172% SFAs and 44.783% UFAs. The saturated fatty acids in Lyngbya and Aphanothece are lauric acid, myristic acid, palmitic acid, and stearic acid, while the unsaturated fatty acids found are oleic acid and linoleic acid. The study paves the way for further research into the industrial applications of cyanobacterial fatty acids, particularly in biofuel production, nutraceuticals, and other biotechnological fields.

Abstract

Arbuscular mycorrhizal fungi (AMF) form mutualistic interactions with plants, including Cynometra cauliflora (Namnam), a tropical indigenous species from the Fabaceae family. This study explores the educational potential of this biological relationship to enrich high school biology education under the Kurikulum Merdeka framework. Field research was conducted at PT Chandra Asri’s Biodiversity Park in Cilegon, Banten Province, Indonesia, an area with rich local biodiversity and a tropical rainforest climate.  The study used a qualitative content analysis approach following an exploratory-descriptive model. Nine naturally growing C. cauliflora individuals were selected for morphological observations and root sampling. Morphological characteristics were documented following standard botanical protocols, while AMF colonization was assessed through root clearing, Phillips and Hayman staining method, and microscopic observation. The percentage of AMF colonization was calculated using the gridline intersect method. Habitat characterization to understand the ecological context. Curriculum analysis reviewed Indonesian biology standards, textbooks, and scientific literature to map potential integrations. Key concepts such as mutualism, nutrient cycling, biodiversity conservation, and plant physiology were identified for curriculum enrichment. The findings suggest that studying C. cauliflora and its AMF association can effectively support Capaian Pembelajaran (Learning Achievement Targets), fostering student skills in scientific methods, environmental awareness, and critical thinking. Incorporating local examples promotes contextual and inquiry-based learning, aligning with the spirit of the Kurikulum Merdeka and strengthening students’ ecological literacy. In conclusion, the mutualistic relationship between C. cauliflora and AMF offers a valuable, locally relevant scientific model for enhancing biology education. It bridges scientific knowledge, cultural understanding, and sustainability, preparing students for real-world ecological challenges.

Abstract

Education is a conscious and planned effort to create a learning atmosphere and learning process that enables students to actively develop their potential, including knowledge, capability, creativity, independence, and a noble character. This study aimed to analyze the effect of Team Games Tournament (TGT)-type cooperative learning on students' interest and learning outcomes regarding the concept of viruses and their role in life. The method employed in this research was a descriptive approach with a quantitative orientation. The research subject involves students of a high school in Serang, Banten. The study showed that the application of the TGT in the learning process significantly increased students' interest and their learning outcomes. Students were more active and competitive between learning groups. In conclusion, the TGT has a positive effect on students’ interest and learning outcomes.

Abstract

The guided inquiry learning model, often called guided discovery learning, is an educational approach that emphasizes student engagement and active learning through exploration and problem-solving under the guidance of a teacher as an instructor. Through guided inquiry learning, this research aimed to examine the correlation between students’ communication skills and scientific literacy ability on the environmental pollution sub-concept. The method used in this research was correlational. The participants in this study were the 10th-grade students of a Senior High School in Serang, Banten. The communication students ' communication skills and scientific literacy abilities were measured by observation sheets and essay questions, respectively. The result showed that the communication skills (oral and written) of the students were categorized as good, with a mean value of 82.27. Meanwhile, students' scientific literacy was categorized as moderate, with a mean value of 82.71. Pearson Product Moment correlation analysis showed that there was a very strong correlation between both values, with a correlation coefficient of 0.890. The linear regression test result showed that communication skills contributed to the student's scientific literacy by as much as 79.2%. It is suggested that applying the guided inquiry model could develop communication skills and students' scientific literacy.
