Abstract

The study entitled "Abundance of Ordo Lepidoptera in The Land Conversion of Ciwidey Pine Forest" aims to obtain the information about the abundance of insects of the ordo Lepidoptera and the influence of climatic factors on the abundance. The research method used is descriptive method, the research design is belt transect, and the sampling techniques used are pitfall trap, hand sorting, beating tray, and insect net. There are 6 stations with 5 quadrants in each. The results of this study obtained 37 individuals from 10 species, 10 genus, and 6 families. Abundance at station one is worth of 2 individuals/m2, abundance at station two is worth of 4 individuals/m2, abundance at station three is worth of 6 individuals/m2, abundance at station four is worth of 6 individuals/m2, abundance at station five is worth of 2 individuals/m2, abundance at station six worth of 10 individuals/m2.

Abstract

Practicum is a learning activity that can develop students' cognitive, affective, and psychomotor abilities. Practicum activities are very important, especially in biology learning. One of the concepts in biology that can be explored through practicum is the activity of the enzyme catalase. This study aims to analyze the practicum worksheet on catalase enzyme activity, specifically focusing on the effect of temperature on catalase activity. The analysis is conducted using Novak & Gowin's vee diagram, which includes focus question, object/event, theory/concept, record/transformation, and knowledge claim. The reconstruction of the practicum procedure is carried out to ensure that the activities align with the fundamental concepts being studied. This allows students to link the practicum procedures with the underlying concepts, enabling them to analyze and build their understanding of the effect of temperature on catalase enzyme activity.

Abstract

ABSTRACTStudents’ numeracy skills, as indicated by the Indonesian Education Report Card, remain low, necessitating efforts to improve them through integration into school instruction, particularly in biology classes. This study aims to analyze the impact of implementing numeracy-based laboratory activities on improving students’ numeracy skills in bioprocessing material. The method used in this study was a pre-experimental design employing a one-group pretest-posttest design. The participants were 37 eleventh-grade students at a high school in Bandung who were studying cell structure and bioprocesses. Data were collected using assessment instruments consisting of pretest and posttest questions, as well as observation sheets for laboratory implementation and a student questionnaire regarding their responses to the laboratory activity. The results of the study indicate that the numeracy-based osmosis laboratory experiment proceeded effectively, with an average implementation score of 95%. Additionally, students’ numeracy skills improved following the implementation of the numeracy-based osmosis laboratory experiment, as evidenced by an increase in the literacy skill category from moderate to high, supported by an N-Gain value of 0.41, which falls within the moderate category. Student responses to the laboratory session were also quite positive, with students providing positive feedback on every aspect assessed. Thus, the implementation of the numeracy-based osmosis laboratory session can support the improvement of students’ numeracy skills.Keywords: Numeracy, Laboratory Experiment, Osmosis in Potatoes, Osmosis Using an Osmometer, Bioprocess.ABSTRAKKemampuan numerasi siswa berdasarkan Rapor Pendidikan Indonesia  masih rendah sehingga perlu upaya untuk meningkatkannya melewati integrasi dalam pembelajaran di sekolah, khususnya pada mata pelajaran biologi. Penelitian ini bertujuan untuk menganalisis dampak penerapan praktikum berbasis numerasi dalam meningkatkan kemampuan numerasi siswa pada materi bioproses. Metode pada penelitian ini adalah pre-eksperimental dengan desain penelitian one-group pretest-posttest design. Partisipan penelitian ini adalah 37 siswa kelas XI di salah satu SMA di Kota Bandung yang sedang mempelajari materi struktur sel serta bioproses. Data penelitian diperoleh menggunakan instrumen tes berupa soal pre-test dan post-test, serta instrumen tes berupa lembar observasi keterlakasanaan praktikum dan kuesioner respons siswa terhadap praktikum. Hasil penelitian menunjukkan praktikum osmosis berbasis numerasi berjalan dengan baik dengan rata-rata skor keterlaksanaan sebesar 95%. Selain itu, kemampuan numerasi siswa mengalami peningkatan setelah diterapkannya praktikum osmosis berbasis numerasi  yang ditunjukkan oleh peningkatan interval kategori kemampuan literasi dari sedang menjadi tinggi dan didukung dengan nilai N-Gain sebesar 0,41 yang berada kategori sedang. Hasil respons siswa terhadap praktikum juga tergolong cukup baik dengan memberikan respons positif pada setiap aspek yang diungkap. Dengan demikian, penerapan praktikum osmosis berbasis numerasi dapat mendukung peningkatan kemampuan numerasi siswa. Kata Kunci: Numerasi, Praktikum, Osmosis pada Kentang, Osmosis dengan Alat Osmometer, Bioproses.
