Abstract

This study aims to identify the diversity of invertebrate species in the Sujono Beach area, Lalang Village, Medang Deras District, Batubara Regency. The study, which was conducted on May 27, 2025, used direct observation and survey methods to collect specimens. The collected invertebrates were then identified taxonomically based on morphological, anatomical, physiological, and behavioral characteristics to the phylum, class, and order levels, followed by wet preservation. The results of the study showed significant invertebrate diversity, especially from the Mollusca and Arthropoda phyla. A total of 14 species of Mollusca were identified, including Anadara antiquata , Turritella communis , and Placuna placenta . In addition, 3 species of Arthropods were also found, namely Macrobrachium rosenbergii and Scylla spp. , and one species of Echinodermata, Tripneustes gratilla . The high invertebrate diversity indicates that the environmental conditions of Sujono Beach are relatively well maintained. This study underscores the potential of Sujono Beach as a natural laboratory for biology education, particularly in invertebrate identification, and highlights the importance of sustainable habitat management and conservation efforts to maintain ecological balance and ensure the long-term sustainability of this species.

Abstract

This study aims to describe the learning interest of An-Nahlu Kisaran Junior High School students in Natural Sciences (IPA). This study uses a qualitative approach with a descriptive method. The research population consisted of all 144 students in grades VII and VIII (5 classes). Data was obtained through a closed questionnaire that measured aspects of learning interest, including feelings of enjoyment, interest, attention, and student participation in science learning. The results of the study show that the majority of students have a good interest in learning, with an average score of 166.0. The results show that 11% (9 students) are very interested, 38% (31 students) are interested, 30% (25 students) are quite interested, 16% (13 students) are less interested, and only 5% (4 students) are not interested in science subjects. Based on gender, there was no difference between the two. Male and female students had the same level of interest in science subjects. Internal factors, such as motivation, curiosity, and attention, as well as external factors, such as support from family, school, and environment, influenced students' level of interest in learning. From the results of this study, it can be said that the learning environment at SMP An Nahlu has supported the development of students' interest in science subjects.
