Abstract

The alang-alang plant is believed to be a good thermal insulation, but unfortunately, it is starting to be abandoned. The purpose of this study was to investigate the use of reed plants (Imperata cylindrica (L.)) as a basic material in the manufacture of ume kbubu of the Timorese tribe. This research was conducted in the South Middle Timor District, East Nusa Tenggara Province. The method used in this research is the triangulation method, which analyzes primary data in the form of observation data, interview data, and literature studies. The results showed that alang-alang (Imperata cylindrica (L.)) is used by Timorese people as an ume kbubu roof due to several factors such as its abundant availability, cheap, strong, durable, and cheap. Through scientific studies, it can be explained that alang-alang (Imperata cylindrica (L.)) has a strong structure, contains high lignin and cellulose, is hydrophobic, and has anti-microbial and antioxidant properties that can help protect plants from pests and diseases. In addition, the influence of the shape of the roof construction using alang-alang which has a hollow structure makes the ume kbubu roof a good thermal insulator. The study of community science and scientific science on using reeds (Imperata cylindrica (L.)) as a basic material for making ume kbubu of the Timorese tribe can be integrated into science learning in schools and universities.

Abstract

Ethnoscience is a science learning approach that implements local wisdom (regional culture) using certain cultural products. Local wisdom can be in food and drink, traditional ceremonies, dances, games, and traditional languages. One of the traditional food-based local wisdom is Papeda. Papeda is a traditional food made from sago flour. The purpose of this research is to reconstruct the original science of the community into scientific science and to review the concept of chemistry in science learning in the process of making papeda. The research method used is descriptive qualitative research through interviews and literature studies. The results of this study indicate that the reconstruction of indigenous knowledge into scientific science from the local wisdom of traditional food typical of North Maluku, namely Papeda, can be used as a learning resource for students because it has relevance to various chemical concepts in science learning. Chemical concepts contained in the process of making papeda are substances and their changes, colloids, physical and chemical changes, thermochemistry, macromolecules (especially carbohydrates), and food and nutrients with their relationship to the digestive system.

Abstract

This research aims to review increasing engineering capabilities through science learning using the case study method. The primary focus of the research is to understand how the integration of science concepts in the engineering curriculum can improve students' technical and analytical skills. The case study was conducted at a vocational high school that applies an interdisciplinary approach between science and engineering. Data was collected through classroom observations, interviews, and questionnaires. The research results show that students who are involved in science learning integrated with engineering can demonstrate an understanding of engineering concepts, problem-solving abilities, and critical thinking skills. In addition, teaching methods that focus on scientific projects and experiments have proven effective in building students' interest and motivation towards the field of engineering. This research concludes that science learning applied in an integrative manner can be an effective strategy in improving students' engineering capabilities

Abstract

Chemistry is a branch of science closely related to daily life. Ethnoscience cannot be separated from science, especially in the study of chemistry. The tradition of distilling eucalyptus oil (Melaleuca cajuputi) on Buru Island has been carried out traditionally for generations. This research aims to analyze and reconstruct the indigenous knowledge of the community in the eucalyptus oil distillation process into scientific knowledge that can be used as a source for learning chemistry. This research used a qualitative approach based on ethnoscience with interview, observation, and documentation methods. Data analysis employs the Miles-Huberman model, which consists of data reduction, data presentation, conclusion drawing, and verification. The results of the research showed that the eucalyptus oil distillation process can be explored in science materials or concepts related to separation techniques, differences in density, phase changes, and substance pressure. The ethnoscience study results indicated the potential of ethnoscience to be applied in chemistry education.

Abstract

This study aims to evaluate the learning programme of the Introduction to Environmental Chemistry course of the Chemistry Education study programme in one of the public universities in Bandung City. This study needs to be evaluated and improved because there are still aspects that are not in accordance with 21st century learning as evidenced by document analysis and learning observations. The method used is a qualitative approach and the CIPP (Context, input, process, Product) evaluation model as a tool to evaluate and improve the lecture programme which focuses on the Context aspect in the form of document analysis of the Semester Learning Plan (SLP), the Input aspect in the form of lecturer interviews and the Process aspect in the form of learning observations. The results obtained from the analysis show that there are several findings that need to be evaluated due to the incompatibility of aspects in the SLP document update such as administrative completeness, the General Skills Aspect (GSA) 1 listed is not in accordance with the Context of Learning Outcomes (CLOs), based on interviews with teaching lecturers it is stated that problem-based learning (PBL) with the context of validated environmental issues in relevant theoretical content and in the aspect of the learning observation process it was found that there were aspects of learning practices that were not in accordance with the SLP document reference. The evaluation also highlighted the importance of updating and adjusting learning media to be more interactive and relevant to the context of environmental issues. The assessment of the last three years shows the potential to further develop programmes can to improve students' higher order thinking skills

Abstract

Misconceptions can significantly hinder the learning process. To address this, various diagnostic instruments such as two-tier (2TMC), three-tier, and four-tier multiple-choice questions have been introduced. However, as the number of tiers increases, identifying misconceptions becomes more complex. Therefore, this study employs the Item Option Characteristics Curve (IOCC) to identify misconceptions by calculating the probability of each option being selected. The Representational Systems and Chemical Reactions Diagnostic Instrument (RSCRDI) was administered to 185 pre-service teachers across three universities in Indonesia. The data was analyzed using Winstep software to generate the IOCC for each item. The analysis revealed that each item in the phenomenon and reasoning tiers contains distractors that could interfere with the option selected by pre-service chemistry teachers. While the alternative answers identified using traditional methods (commonly used since the introduction of 2TMC) were mostly similar to those identified by IOCC, the IOCC provided more detailed insights. Specifically, it highlighted unexpected curves after 0 logits, identified less effective distractors, and revealed inconsistencies in the most influential distractors. These findings suggest that the IOCC provides richer, more detailed information and can be a valuable alternative framework for analyzing 2TMC items to unfold misconceptions.
