Abstract

Practicum is a process to gain meaningful learning experience through hands-on and hands-on activities. Factors that cause constraints in biology practicum include incomplete tools, unavailable materials, and unavailability of practicum guides. The practicum guides circulating in schools also have various problems. Therefore, it is necessary to reconstruct the practicum guide and the existence of tools and materials that can be an alternative or solution that can overcome problems in the practicum of catalase enzyme. This research uses a qualitative descriptive method with the ANCORB flow (Analysis-Test-Reconstruction-Test). The samples used were five pieces of catalase enzyme practicum guides (LKS) from various sources with sampling techniques in purposive sampling. The analysis showed that the average LKS of catalase enzyme had a fairly good score but still needed LKS reconstruction that could measure the work of catalase enzyme quantitatively accompanied by alternative tools and materials in catalase enzyme practicum. The alternative tools that can be used are tools assembled using a syringe and a three-way stopcock. At the same time, alternative materials that can be used are water with acidic and alkaline pH, lime, lime water and clothes bleach as a substitute for hydrogen peroxide

Abstract

Laboratory practicum in science learning is considered important, especially in the context of the Independent Curriculum. Science-based learning is needed to encourage the development of students' skills and character, supported by practical activities. Good practical activities not only allow students to understand scientific concepts but also train students to apply scientific methods effectively. The aim of this research is to analyze, reconstruct, and design simple tools to improve Laboratory Activities Designed (LAD) on the respiratory air sub-material. The research method used is descriptive to show existing phenomena. Analysis was carried out using Vee Diagrams; then trials were carried out, reconstruction and design of simple tools, second trials, and revisions. The results of the analysis show that the five LAD samples are still in the very poor category, so improvements need to be made to avoid mistakes in the future. Researchers carried out LAD reconstruction, which included appearance, title, purpose, tools and materials, procedures, and questions. Reconstruction is supported by designing a tool in the form of a simple spirometer. The design of this simple tool can be assigned to students to train creativity and solve problems. It is hoped that the results of this analysis and reconstruction can help teachers in designing LAD for other materials in the future to suit learning objectives and the applicable curriculum.Abstract. Praktikum laboratorium dalam pembelajaran sains dinilai penting terutama dalam konteks Kurikulum Merdeka. Pembelajaran berbasis sains diperlukan untuk mendorong pengembangan keterampilan dan karakter siswa dengan didukung kegiatan praktikum. Kegiatan praktikum yang baik tidak hanya memungkinkan siswa untuk memahami konsep sains, tetapi juga melatih siswa dalam menerapkan metode ilmiah dengan efektif. Tujuan penelitian ini yaitu untuk menganalisis, melakukan rekonstruksi dan merancang alat sederhana untuk menyempurnakan Laboratory Activities Designed (LAD) pada sub materi udara hasil pernafasan. Metode penelitian yang digunakan yaitu deskriptif untuk menunjukkan fenomena yang ada. Analisis dilakukan menggunakan Diagram Vee, selanjutnya dilakukan uji coba, rekonstruksi dan perancangan alat sederhana, uji coba kedua, dan revisi. Hasil analisis menunjukkan bahwa kelima sampel LAD masih dalam kategori sangat buruk sehingga perlu dilakukan perbaikan untuk menghindari kekeliruan di masa yang akan datang. Peneliti melakukan rekonstruksi LAD yang mencakup tampilan, judul, tujuan, alat dan bahan, prosedur, dan pertanyaan. Rekonstruksi didukung dengan perancangan alat berupa spirometer sederhana. Perancangan alat sederhana ini dapat ditugaskan kepada siswa untuk melatih kreativitas dan memecahkan masalah. Hasil analisis dan rekonstruksi ini diharapkan dapat membantu guru-guru dalam merancang LAD materi lain di masa depan agar sesuai dengan tujuan pembelajaran dan kurikulum yang berlaku.

Abstract

This study identifies the values embedded in the local wisdom of the Jolotundo Temple’s Ruwat Petirtaan tradition and integrates them into biology learning within the Merdeka curriculum. A descriptive qualitative method was employed, using interviews and observations, and analyzed through triangulation and inductive approaches with an emphasis on meaning over generalization. Findings indicate that the tradition embodies gratitude for the abundance of water and natural resources across the preparation, implementation, and closing stages. It functions as a form of environmental conservation. This local wisdom can be integrated into Phase E Biology content, particularly biodiversity and conservation, ecosystems, and environmental change. The results serve as a reference for developing teaching materials, modules, student worksheets, project assignments, and assessment items, while also encouraging the incorporating of local wisdom into policies, conservation programs, and educational practices that are contextual, participatory, and sustainable. The implication is that cross-stakeholder commitment through school–community collaboration and continuous evaluation is required to ensure tangible impacts on learning, environmental stewardship, and the strengthening of cultural identity.
