This research aims to determine the effect of substrate and water type on the cultivation of Sumba seaworm (Nyale) and develop an authentic inquiry project-based practicum instrument on Nyale as Polychaeta to improve critical and creative thinking skills of prospective science teachers. The results of experimental research showed that the substrate of sea sand and sea coral can be used in Nyale cultivation because it can provide a higher survival rate for this organism. Cultivation without substrate causes Nyale to survive less. Sea water is needed to be used in cultivation. The development of an authentic inquiry project practicum instrument about Nyale shows that the instrument is feasible to be used in practicum to improve the critical and creative thinking skills of prospective science teachers. This research contributes well to the development of authentic science learning that can create meaningful science learning for students. This research also supports a problem solver for current issues in the sustainable development goals (SDGs).

The type of research used is qualitative research presented in descriptive form based on spoken and written words. The subject of the study was a grade VIII student of SMPK St. Paul Karuni. Data collection techniques used are carrying out teaching and learning activities, written tests, interviews, and documentation. The data analysis techniques used are data reduction, data presentation, conclusion drawing. The results of this research show that there are 3 types of errors made by students, namely (1) conceptual errors, at this stage overall there are still many students who make mistakes in writing down what they know and are asked about the questions, some even don't write them down because they don't understand the questions. (2) principal errors, at this stage there are still many students making mistakes in using formulas and some write some of them down and some even don't write them at all. (3) procedural errors, all students make mistakes at this stage. This happens because students do not know the method or steps to solve the problem and make mistakes in the calculation process, so it can be concluded that the level of mathematical errors for class VIII B students at SMPK St Paulus Karuni is still very high.

This study aimed to implement ethnoscience in analyzing pandan mat making in Wewewa Tengah and evaluating its implication as a learning source in science education. This research focused on studying the pandan mat-making process in Wee Patando Village and identifying its scientific contributions to traditional practice. Applying a qualitative research method, the data were collected through observation, interviews, and documentation. Meanwhile, the research instruments used are observation sheets, interview guides, and documentation. The data were analyzed through several stages: reduction, data presentation, and conclusion drawing. The results reveal that the pandan mat-making process involves several stages, including collecting pandan leaves, sorting, removing its thorns, drying, ware (scraping), rolling, tirri (dividing), weaving, melekuk (locking), and dumbi (placing pandan). The main challenge is in the drying process of pandan, which is affected by high humidity during the rainy season and may impact the quality of the mats. This study's contribution lies in applying scientific concepts to the traditional pandan mat-making process, such as plant physiology, the leaf structure and its function, the physical properties of materials, and principles of heat transfer and friction. The findings emphasize that the pandan mat-making process can serve as a concrete example for understanding science subjects, particularly in plant physiology and material physics. In science education, this research recommends integrating ethnoscience knowledge from pandan mat-making into the curriculum to enrich students' learning experiences. By understanding how scientific concepts are applied in traditional practices, students can see the relevance of science in daily life and enhance their comprehension of academic material through concrete and relevant examples.
