Animal-plant interactions are crucial for understanding the ecological dynamics and predicting ecosystem changes. This study explores the role of the invasive plant Maesopsis eminii in the Bodogol Nature Reserve, Gunung Gede National Park, West Java, Indonesia, focusing on its interaction with diurnal vertebrate species. Primates, including Javan gibbon and Javan langur, were identified as primary consumers of Maesopsis eminii, with Javan gibbon showing the highest consumption rates. Dietary analysis revealed that both primate species utilized M. eminii fruits and leaves, whereas Javan gibbons relied more on Maesopsis eminii than Javan langurs. Other vertebrates, such as squirrels and birds, are occasional visitors with minimal fruit consumption. This study highlights that Maesopsis eminii is a primary resource of Javan gibbon, Javan langur, and Javan surili. This nearly year-round fruiting plant is crucial for supporting primate populations, especially given its contribution to their diet. Considering the mutualistic interaction between Maesopsis eminii and its visitors, the Javan gibbon was the only species that probably dispersed seeds through endozoochory, making this primate species a crucial part of the dispersal of Maesopsis eminii in Gunung Gede National Park. Because invasive plants can threaten native flora and fauna, future studies must emphasize balancing the beneficial and detrimental effects.

Pertumbuhan media pers yang pesat di Indonesia pasca reformasi tahun 1998, telah menimbulkan tantangan besar. Dari perkiraan Dewan Pers terkait jumlah media di lapangan sekitar 40-50 ribu, hanya kurang dari 10 persen yang memenuhi standar profesional sebagai media pers. Artinya, produksi berita belum sesuai standar professional, yakni belum mengikuti kaidah-kaidah jurnalistik dan mengikuti kode etik jurnalistik. Dengan tidak melakukan verifikasi atau mencampur-adukan opini-opini pribadi dalam “berita” yang ditulis, maka akan dihasilkan berita yang tidak berkualitas bagi masyarakat, sekaligus produksi hoax menjadi marak. Pada saat yang sama, kehidupan pers di Indonesia juga harus berhadapan dengan teknologi digital yang mempengaruhi cara orang memproduksi konten berita. Saat ini semua orang, termasuk orang yang tidak memahami etika dapat menulis informasi bagi publik. Inilah yang mendorong penulis melakukan Pengabdian Kepada Masyarakat dengan melakukan sosialisasi Kode Etik Jurnalistik, sebagai upaya meningkatkan literasi media yang dapat mengedukasi masyarakat bagaimana mengenali berita yang benar dan membedakannya dengan hoax. Target sasaran pengabdian adalah pelaku UMKM Taman Jajan Permata Pamulang, di Tangerang Selatan, yang menggunakan social media dalam memasarkan produk mereka. Dengan metode pemaparan materi, simulasi dan group discussion di antara peserta, juga dengan narasumber, peserta dapat memahami dan mengidentifikasi berbagai jenis berita, apakah itu hoax atau bukan.

Several ecosystems have currently experienced damage due to several factors, both natural and due to human activities. Efforts to minimize this damage can be done made by encouraging students to be aware of the natural resources around them, one of which is based on local wisdom. This study aims to analyze the relationship between knowledge of the concept of an ecosystem based on local wisdom and environmental sensitivity with ecological behavior. This study uses a quantitative descriptive approach with a survey method. Respondents consisted of 168 students of class X IPA SMAN 97 Negeri Jakarta, who were taken using a simple random sampling technique. Data testing in this study includes normality, homogeneity, and linearity for correlational and regression analysis. The results of the study showed that there was a positive and strong correlation between knowledge of ecosystem concepts based on local wisdom and ecological behavior, which was 64,8%. Based on these results, the implication in this research is that knowledge of ecosystem concepts based on local wisdom can be increased through strong ecological behaviors.

The broad scope of biology and the many sources of biology reading requires eleven grade students to think critically about sorting out information to develop and support students' critical thinking skills. CirGi is an integration of the cooperative integrated reading and composition (CIRC) learning model and guided inquiry (GI) that emphasizes reading and writing activities, accompanied by guidance from the teacher. This study aimed to analyze the influence of CirGi's learning model on students' critical thinking skills. This research uses a quasi-experiment method with pre-post control group design. The sampling technique used purposive sampling, namely 104 high school students. Data collection was carried out using instruments of critical thinking skills in the form of essays, questionnaire responses of students to learning, and observation sheets of syntax implementation. The data analysis technique used was one-way ANCOVA. After controlling for the pretest scores, the CirGi learning model's influence on students' critical thinking skills was influenced. This learning model was appropriate for learning biology, so it can regrow the activities of reading science books that impact students' critical thinking skills.

In Biology learning, technology becomes a tool to facilitate 21st-century learning trends that are digitally oriented, distanced, internet-integrated learning materials, as well as being open and independent. This trend is a challenge because the results of a preliminary study at SMAN 37 Jakarta showed that 42.3% of students experienced a decline in their biology learning outcomes during the distance learning period, especially in the Excretory System chapter. Of these, 61.5% thought the decline was due to low self-regulation. This study aims to develop learning materials in the Excretory System through Moodle to increase students’ self-regulation. The method used is research and development with the Borg and Gall development model using the Moodle platform. The development of learning materials was validated by 5 experts on aspects of the material, learning materials, and language. The result is the scope of the material aspect is 90.4%, the learning material aspect is 90.8%, and the language aspect is 88%, all of which meet the very feasible criteria. The learning materials were tested on 30 respondents and obtained pre-test and post-test scores on self-regulation. The results were tested using the paired sample t-test showed a significance value (p) = 0.001< 0.05. This result illustrated that the use of Excretory System learning materials can increase students’ self-regulation.
