Abstract

Bakteri lipolitik berperan dalam mendegradasi sampah yang mengandung lipid dengan bantuan enzim lipase. Penelitian  ini bertujuan untuk mengetahui karakteristik bakteri lipolitik dari tanah Tempat pembuangan sementara (TPS) di Kota Kupang. Prosedur penelitian meliputi isolasi bakteri, karakterisasi makroskopis, karakterisasi mikroskopis dan uji aktivitas lipolitik. Hasil penelitian menunjukkan bahwa ditemukan 8 isolat bakteri yang diberi kode L1A, L2A, L3A, L4A, L5A, L6A, L7A, dan L8A, Karakterisasi makroskopis ditemukan bakteri yang memiliki bentuk, tepian, elevasi dan warna yang berbeda, karakterisasi mikroskopis ditemukan bakteri dengan kode isolat L1A, L2A, dan L7A merupakan bakteri gram negatif, sedangkan L3A, L4A, L5A, L6A dan L8A merupakan bakteri gram positif. Hasil uji aktivitas menunjukkan bahwa semua isolat memiliki aktivitas lipolitik dengan adanya zona kuning di sekitar koloni bakteri dimana isolat L1A mempunyai indeks lipolitik terbesar yaitu 10,7 mm sedangkan isolat L3A mempunyai indeks lipolitik terkecil yaitu 4 mm. maka dapat disimpulkan bahwa bakteri lipolitik dapat ditemukan pada tanah TPS di Kota Kupang dengan karakteristik yang berbeda dan mempunyai aktivitas dalam mendegradasi lipid.

Abstract

This study aims to analyze the need for developing E-modules Argument Driven Inquiry (ADI) with Socio Scientific Issues (SSI) context on environmental change material to empower students' scientific argumentation skills. The research method used is descriptive qualitative method with data collection techniques through interviews and questionnaires. The subjects of this study were biology teachers and 60 students of SMA Negeri 4 Surakarta. The results of the needs analysis showed that teachers and students need technology-integrated teaching materials in the form of ADI E-modules with SSI context on environmental change material. The development of ADI E-modules with SSI context is expected to be an alternative learning solution that is innovative and effective in improving the quality of biology learning which has implications for empowering students' scientific argumentation skills.

Abstract

Scientific argumentation is a key skill and an important variable that plays a central role in biology learning, which in practice has not been well trained. The purpose of this study was to determine the effect of debate activities supported by artificial intelligence as a tool to improve students' scientific argumentation skills. This study adopts a quantitative descriptive method by integrating a quasi-experimental approach. The research sample consists of 72 tenth-grade students from State High School 7 Surakarta, divided into experimental and control groups. A scientific argumentation test instrument in the form of essay questions was used to analyze the final synergistic effect of the intervention provided. The research findings indicate that there are significant differences between the control and experimental groups in certain elements, both in terms of argumentation structure criteria (Claims and Data) and argumentation quality criteria (Organization, Sufficiency, and Clarity) with a p-value 0.05, indicating that AI-supported debates only influence initial elements, thus concluding that they are not yet effective across all elements of scientific argumentation skills. This highlights the need for sufficient time and more targeted instruction to maximize the development of students' scientific argumentation skills.
