Indonesia possesses extraordinarily high biodiversity, including numerous bird species inhabiting tropical rainforests. This study aimed to inventory and characterize birds in Citalahab Village, Gunung Halimun Salak National Park, one of Indonesia's largest tropical rainforest areas. Surveys were conducted on May 2 and 3, 2024, using transect methods. The research identified 70 bird species from 6 orders, with Passeriformes being the most abundant. The relative abundance index highlighted the dominant presence of the Collocalia linchi in the region. Environmental factors such as vegetation type and temperature significantly influenced bird distribution and diversity. The findings underscore the critical role of forest habitat conservation in preserving bird species diversity. This research contributes valuable insights into the understanding of bird diversity in Indonesian tropical rainforests and advocates for further conservation efforts.

Pengaruh Pemberian Berbagai Konsentrasi Timbal (Pb) terhadap Pertumbuhan Bibit Mangrove Rhizophora stylosa

Mangroves are a type of higher plant found in coastal areas that play many roles, one of which is as a bioaccumulator of harmful pollutants. One such harmful pollutant is the heavy metal Lead (Pb). This study aims to determine the effect of various concentrations of lead on the growth of mangrove seedlings, specifically Rhizophora stylosa. This research is an experimental study using a Completely Randomized Design (CRD). There were four lead concentration treatments: K0 = 0 ppm (control); K1 = 0.1 ppm; K2 = 1 ppm; K3 = 10 ppm; and K4 = 100 ppm. Each treatment was repeated five times, resulting in 25 experimental units. The seedlings used were Rhizophora stylosa, approximately 8 months old, with an average height of 70 cm and an average of 8 leaves. The growing medium used was homogenized mud soil. Before the experiment, the plants were acclimatized for 1 week. The treatment involved a solution of Pb acetate administered every day for 6 weeks. The parameters measured included plant height increase (cm), leaf area (cm²), increase in the number of leaves, increase in the number of shoots, and increase in stem diameter (cm). Based on observations over the 6-week treatment period, the average stem growth was between 0.12-0.28 cm, with no increase in stem diameter, an average leaf area increase of 0.14-0.38 cm², an increase in shoots by 1-3, and an increase in the number of leaves by 2-6. The ANOVA results at a significance level of 5% indicated that lead concentrations of 0-100 ppm did not significantly affect the growth of Rhizophora stylosa seedlings.

Riri Hariani — Sun, 21 Jul 2024 00:00:00 +0000

Science learning in schools often emphasizes rote memorization of content, rather than applying knowledge in real-life contexts. The objective of this research is to explore the development of teaching materials based on mangrove ecotourism and their effectiveness in science education. The method employed in this study is literature review. Articles were reviewed through a national-level literature search using selected sources (databases), namely Google Scholar. The search terms included "mangrove ecotourism," "ecosystem," "science," and "teaching materials”. Ten articles published in national or international journals within the last 10 years were utilized. The research findings indicate that mangrove ecotourism materials can be effectively used in junior high school science education. Through interactive and field-based activities, students can grasp ecological concepts, biodiversity, conservation, and sustainability. Integrating mangrove ecotourism into the science curriculum not only enriches learning experiences but also enhances students' awareness and concern for the environment.

Identifikasi Sumber Belajar Lokal untuk Mendukung Inovasi Pembelajaran Biologi

This research aims to identify local learning resources as an effort to support innovation in high school biology teaching in Mataram City and West Lombok Regency. This study involves exploration using observation and interviews with teachers and students to collect data on the potential of local learning resources and their application in biology education. The results indicate that there are various potential local learning resources, such as school gardens, city parks, urban forests, coastal areas, and local agro-tourism sites. The identification and utilization of these local learning resources have proven to enhance students' interest and motivation, as well as provide a more contextual and relevant learning experience. Data analysis shows that while there is significant potential in utilizing local learning resources, there are still challenges in its implementation.

Review: Penerapan Model Pembelajaran PjBL untuk Meningkatkan Keterampilan Proses Sains dan Hasil Belajar Peserta Didik pada Mata Pelajaran Biologi

Nining Suryani — Wed, 31 Jul 2024 00:00:00 +0000

21st-century learning is focused on the development of students' moral and intellectual character as well as various skills to face diverse challenges. One student-centered learning model is Project-Based Learning (PjBL). In project-based learning, students engage in tasks that encourage them to solve real and relevant problems within the context of the real world, rather than merely absorbing information. This research aims to analyze the application of the PjBL model in enhancing science process skills and student learning outcomes in high school biology subjects. This type of research is a literature review. The study was conducted by reviewing 20 articles from national and international scientific journals using databases such as PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. The keywords used in the literature search were: project-based learning, PjBL, science process skills, and learning outcomes. The results indicate that the implementation of the Project-Based Learning (PjBL) model in high school biology subjects can improve science process skills and student learning outcomes.

Upaya Meningkatkan Pemahaman Konsep Matematika Siswa Melalui Penerapan Model CORE di MA NW Putra Narmada Tahun Pelajaran 2023/2024

Sabrun Sabrun — Wed, 31 Jul 2024 00:00:00 +0000

This study was conducted as an effort to enhance students' understanding of mathematical concepts through the application of the CORE (Connecting, Organizing, Reflecting, Extending) model at MA NW Putra Narmada, West Lombok Regency. This research is a Classroom Action Research (CAR) carried out in two cycles with stages of planning, implementation, observation, and reflection. The subjects of this research are 34 students from the 10th grade at MA NW Putra Narmada. The research instruments used are observation sheets and test sheets. The data collection techniques employed are testing and observation. The data analysis techniques used are both quantitative and qualitative data analysis. The results of this study indicate an improvement in the understanding of mathematical concepts among the 10th grade students of MA NW Putra Narmada after applying the CORE learning model. Test results show an increase in students' understanding of mathematical concepts in cycle I to 57% with a sufficient category, while in cycle II, it increased to 95.00% with an excellent category. Observation results show 68% in cycle I with a good category and 96.00% in cycle II with an excellent category.
