Abstract

Pembelajaran bagi siswa dapat dilakukan dengan pendekatan ilmiah seperti penyelidikan kebenaran suatu hipotesis melalui observasi dan eksperimen. Penelitian ini menampilkan model praktikum verifikasi. Perubahan warna menjadi coklat pada buah disebut dengan browning atau pencoklatan yang disebabkan adanya reaksi enzimatis (antara enzim fenolase pada buah apel dengan oksigen) sehingga membentuk pigmen melanin berwarna coklat. Pencokelatan enzimatis pada buah dalam proses pengolahan merupakan masalah yang serius, khususnya pada komoditas buah apel, hal ini dikarenakan dapat mengurangi kualitas produk secara visual dan menurunkan minat konsumen. Penelitian ini bertujuan untuk mengamatii faktor-faktor penghambat proses browning pada buah. Penelitian dilaksanakan pada Juni 2024 menggunakan metode eksperimental yang disusun dalam Rancangan Acak Lengkap (RAL). Analisis dilakukan menggunakan aplikasi digital color detector (Aplikasi android) untuk mengamati perubahan HVS warna pada sample. Hasil penelitian/praktikum didapat data berupa ektrak jeruk nipis paling berpengaruh terhadap penghambatan proses enzimatik browning pada buah.

Abstract

Education for Sustainable Development (ESD) is a program designed to achieve sustainable development goals. In the 2013 curriculum, ESD has been used as one of the bases for teaching science to students. However, the existence of the Covid-19 outbreak in Indonesia has had an effect on science learning activities in junior high schools, so that face-to-face learning has been shifted to online learning. This study aims to analyze activities in online learning, the obstacles experienced by teachers and students, and their effectiveness in implementing ESD principles. The method used is descriptive qualitative to describe online learning at one of the Junior High School (SMP) and Islamic Junior High School (MTs) in West Java. The Researchers used data from the analysis of the teacher's lesson plan and semi-structured interviews with 2 teachers and 2 students. Data analysis was performed by reducing data, presenting data, and drawing conclusions. The results show that online learning is less effective in implementing ESD values because the material presented is limited and learning is only one-way (teacher center). Online learning is carried out using WhatsApp, Google Classroom, and e-learning media with obstacles in the form of internet network instability and a lack of student motivation. Therefore, it is hoped that the teacher can use a learning model that is more attractive, student-centered, and can implement the principles of ESD.

Abstract

The era of industrial revolution 4.0 requires us to be "familiar" with the digital world. Not just doing hobbies, people can even do work with the help of digital tools. In facing challenges in the digital era in the form of a rapid flow of information, critical thinking skills are really needed. Students' critical thinking skills need to be trained to solve contextual problems, one of which is through implementing Project Based Learning (PjBL) in learning. This research aims to see the effectiveness of PjBL on students' critical thinking skills. This research is a quasi-experimental research with a one group pretest-post-test design. The population in this study were undergraduate students of the Biology education program in Universitas Jambi. The instrument used in this research is essay questions along with a rubric for assessing critical thinking skills. Data were analysed using SPSS 25.00 software. The results of the analysis show that there is a significant difference between the pretest and post-test scores for students' critical thinking abilities. It can be concluded that PjBL is effective in improving critical thinking skills.

Abstract

This study aims to analyze the Technological Pedagogical Content Knowledge (TPACK) competence of biology teachers in the use of instructional media in high schools in Kuala Tungkal. This research employs a descriptive method with a quantitative approach, involving 7 biology teachers from 3 public high schools in Kuala Tungkal as subjects. Data were collected through questionnaires, interviews, and observations. The results indicate that the technology-based instructional media used by teachers vary according to the needs of the materials being taught. In terms of technological knowledge, the average percentage obtained was 77.78%, which falls under the Good category, while the pedagogical content knowledge aspect scored an average percentage of 84.4%, categorized as Very Good. The conclusion of this study suggests that biology teachers in Kuala Tungkal have good TPACK competence in the use of instructional media. Recommendations from this study include the enhancement of training for developing more advanced technology-based instructional media, such as e-modules and interactive simulations, to further improve the quality of biology education.

Abstract

This study aims to test the feasibility of a case study-oriented textbook in the course of educational digital psychology. This research is an R&D study using the ADDIE development model. The study was conducted on 2nd semester biology students in the Biology Education Study Program, University of Jambi. The instruments used were expert validation questionnaires, lecturer and student response questionnaires on the quality of the book. The data analysis techniques used were expert validity score tests and student response questionnaire scores. In the validity test, the results of the study showed that the developed textbook was very feasible to be used in learning activities with a percentage score of 95% in terms of material feasibility, and 90% in terms of media feasibility. So, from the results of the expert assessment, it can be concluded that the case study-oriented textbook in the Educational Digital Psychology course is very feasible to be used in learning activities.

Abstract

The nervous system is a complex biological because the material is still abstract. The method used by teachers is the lecture method which causes students to have difficulty in understanding the material. To overcome this, a case study-based e-Module is needed that can provide students with cases related to the material and be a solution to students' difficulties related to minimal learning in class. This study aims to develop a case study-based e-Module on the nervous system material and analyze the feasibility of the developed product. This study uses the ADDIE development model consisting of Analyze, Design, Develop, Implement and Evaluation. The results of the study showed that the developed e-Module obtained a percentage of 91.66% with the category "very feasible" in the material validation. At the media validation stage, a percentage value of 94.11% was obtained with the category "very feasible". The biology teacher's perception of the quality of the developed product obtained a percentage of 91.17% with the category "very good". Small group trials with students obtained a percentage of 95.20% with the category "very good" and large group trials obtained a percentage of 94.68% with the category "very good". Thus, it can be concluded that the product developed is feasible and practical and received by teachers and students as a learning tool that supports students' learning process on the nervous system material.
