Abstract

E-module is considered as an effective learning media to create an interactive learning environment. In spite of that it is rare to find the research that examines the development of e-module based on Problem-Based Learning model that integrates Socio-Scientific Issues on argumentation skills to students. This research aims to develop students’ argumentation skills through problem-based e-module with socio-scientific issues topics. The researcher used pre-experimental method with one-group-pretest-posttest design. The e-module was implemented to 36 students of Biology Education, State University of Malang, for the 2nd-year from November to December 2022. The research sample was selected by non-random sampling. The research samples were selected by non-random sampling. The research data were collected by opened-ended questions to assess the students’ argumentation skills and categorized based on the argumentation skills rubric. The data were analyzed based on the increase of pre-test and post-test scores by using Normalized Gain (N-Gain). The result of the N-Gain calculation showed a score of 0.46 which means the students’ argumentation skills developed in the moderate category after the implementation of using problem-based e-module with socio-scientific issues topics. The problem-based e-module with socio-scientific issues topics can train students to identify the problems, analyze data and evidence to give problem-solving solutions packaged of complex argumentation.

Abstract

The fragrant Citronella oil derived from Cymbopogon nardus (L.) Rendle has many benefits, one of which is as an antibacterial. This research aims to identify the chemical compounds present in the essential oil Citronella obtained from a local distillery in Anding Village, Suliki District, Gunung Mas 50 Kota Regency, Province West Sumatra. The essential oil Citronella was identified using Gas Chromatography-Mass Spectrophotometry (GC-MS) at the BRIN (National Research and Innovation Agency) chemistry laboratory in Serpong, South Tangerang, Banten. The results showed that the essential oil Citronella met the requirements of SNI 06-3953-1995, and after being identified with GC-MS, 39 chemical compounds were found, with 3 compounds having high concentrations in the essential oil: Citronellal (24.57%), Citronellol (11.69%), and Geraniol (15.59%).

Abstract

Utilization of biodiversity, especially plants as ingredients for traditional medicine is a tradition of rural communities in Indonesia. Villagers know traditional medicine from their ancestors which has been passed down from generation to generation. However, knowledge regarding the use of plants for traditional medicine has not been well documented, proving that this knowledge is only mastered by the elderly. Ethnomedicine study is one solution that can be done to overcome this problem. The diversity of plants used by the community for treatment has the potential as a biological reference source. This study aims to identify plants used for traditional medicine by the people of Menoreh Village and to develop and produce a product in the form of a reference book based on the results of the ethnomedicine study conducted. This study uses ethnographic study methods and 4D Research and Development (R&D) models but only up to the develop stage. Collecting data using the method of observation, interviews, and questionnaires. Data analysis techniques using qualitative and quantitative descriptive analysis. The results showed that there were 79 species of plants belonging to 27 orders. The plants most often used are kencur and awar-awar. The most widely used part of the plant is the leaf, the most common processing method is boiling, the dominant way of use is drinking and the disease that is most commonly treated with medicinal plants, namely coughs and colds. good and worth using with revision. The feasibility assessment of reference books by media experts is 74.6% with sufficient eligibility criteria and is suitable for use with revisions. The overall feasibility of reference books obtained an average value of 82.46% with good criteria.

Abstract

Environmental problems that occur today are inseparable from human conditions or interactions with the environment, both biotic and abiotic environments. The low awareness of the Indonesian people towards their environment can also be influenced by their lack of environmental awareness. The purpose of this study is to determine the level of environmental literacy possessed by students of MAN 1 Malang City. This type of research is survey research. The sample of this research was 233 students of class XI and XII majoring in science and social studies. The instrument used in this study was an environmental literacy test adapted from the Middle School Environmental Literacy Survey/Instrument (MSELS). The average value of students' environmental literacy is 57.1 in the currently category.

Abstract

The use of prohibited food additives such as formalin is still often found, especially in the school environment. In fact, based on the 2012 Minister of Health Regulation No. 033, formalin is prohibited as a food additive. This phenomenon requires people to be quite observant in choosing food tools. In addition, many people think that the formalin content test can only be done through the laboratory, the formalin test can also be done by a simple reagent containing anthocyanin on dragon fruit skin. So, the researchers designed a simple STEAM-based media with a natural formaldehyde-detecting ingredient, namely red dragon fruit peel extract. This design is divided into two parts, namely the design of simple steam-based media and the manufacture of natural dragon fruit peel extract to detect the content of formaldehyde additives in food. The design was carried out by Grade VIII students at SMP Negeri 6 Jember. The final tool produced is a detector marker.

Abstract

The purpose of this research is to describe the characteristics of STEM-based teaching materials and to find out the increase in scientific literacy skills of junior high school students. The method used in this research is research and development. The design of this study uses the ADDIE model, with the stages of analysis, design, development, implementation, and evaluation. The trial design used the One Group Pretest-Posttest Design. The test subjects were class VII SMP Walisongo Mayang. The characteristics of this integrated STEM-based textbook and local potential contain material on temperature and heat, complemented by student environmental events as well as practicum procedures and project creation related to STEM aspects for students. The results of the validity of the textbooks developed by the validator show very valid criteria, with the results of the feasibility test using a student response questionnaire showing textbooks included in the practical category and good for students. As well as the results of the effectiveness of textbooks show that they can improve students' scientific literacy skills which are marked by an increase in pretest to posttest scores (t-test value 25,668 and n-gain 0.77). Developing textbooks for students makes it possible to develop them more broadly with STEM development as well as the problems and challenges faced by students in the surrounding environment.
