Jurnal Banua Oge Tadulako (JBOT) is a national recognized journal in the field of education. It is published twice a year (May dan November). The aim of this journal is to publish high quality studies in the areas of instruction, learning, teaching, curriculum development, learning environments, teacher education, educational technology, and educational developments. Studies may relate to any level of education, from high school to higher education. The studies can be the results of field research and literature review. JBOT, being a national accredited journal, our editorial advisory board members are from various countries around the world. The manuscripts sent to the Journal are always reviewed by two members of the Editorial Board (double blind peer review), and in some cases, if necessary, by another member of the Board.

Abstract

A Classroom Action Research at the 9th-Year Students of SMP Negeri Model Terpadu Madani Palu, 2019/2020 academic year aimed at finding out the students’ real portrait English writing performave.  The truism showed that the teachers of English had not found effective assessment strategy to elicit accurate assessment results about their students’ actual performance. Therefore, it is necessary to develop and find a new assessment strategy to solve this problem. It is found that the efective assessment strategy is classroom-based assessment with the following procedures. First, preparation or introductory step that include three activities: (1) introducing the idea of classroom-based assessment and procedure of its implementation to students, (2) specifying/ informing teaching and assessment objectives and selecting writing tasks, and (3) specifying aspects to be assessed and criteria of assessment. Second, assessment activities include four activities: (1) observing students’ performances in writing process, (2) assessing students’ knowledge on basic skills for paragraph writing, (3) getting students’ responses and feelings toward the learning activities, and (4) assessing/evaluating students’ writing product as product assessment. For Junior High students, holistic assessment is recommended

Abstract

Tujuan penelitian adalah untuk mengetahui ada tidaknya pengaruh model pembelajaran kooperatif tipe Teams Games Tournament disertai Joyful Learning terhadap hasil belajar fisika siswa kelas X SMAN 5 Palu. Jenis penelitian yang digunakan yaitu eksperimen kuasi dengan desain the non-equivalent control group design. Sampel dipilih menggunakan teknik purposive sampling. Kelas XI IPA 3 sebagai kelas eksperimen dan kelas XI IPA 4 sebagai kelas kontrol. Instrumen yang digunakan berupa tes hasil belajar fisika dalam bentuk pilihan ganda yang telah di uji coba. Berdasarkan hasil pengolahan data, untuk kelas eksperimen diperoleh rerata skor tes akhir adalah 13,63 dengan nilai ketuntasan klasikal 54,52 % dengan standar deviasi yaitu 3,17. Untuk kelas kontrol diperoleh rerata skor tes akhir adalah 8,23 dengan nilai ketuntasan klasikal 32,92 % dengan standar deviasi 2,91. Dari hasil analisa data tes akhir yang ada diperoleh nilai ttabel 1,67 sedangkan nilai thitung 7,43. Hal ini menunjukan bahwa thitung berada didalam daerah penolakan H0. Dengan demikian H0 ditolak dan H1 di terima. Hal ini menunjukan bahwa terdapat perbedaan yang signifikan antara rata-rata nilai kelas eksperimen dan kelas kontrol pada taraf nyata berbeda secara signifikan dengan kelompok siswa yang mendapatkan model Direct Instruction. Maka dapat disimpulkan bahwa terdapat pengaruh model pembelajaran kooperatif tipe Teams Games Tournament disertai Joyful Learning terhadap hasil belajar fisika siswa kelas X SMAN 5 Palu.

Abstract

Research on the analysis of vitamin C levels and antioxidant activity in red dragon fruit (Hylocereus polyrhizus) has been carried out using UV-Vis spectrophotometry. In this study, fresh dragon fruit flesh was mashed with a blender and the maceration method with 96% absolute ethanol solvent was carried out three times. The meseration results were evaporated using a rotary evaporator to obtain a thick extract. In the DPPH free radical scavenging test and the determination of vitamin C levels in red dragon fruit extract (Hylocereus polyrhizus) the original vitamin C was used as a comparison. In determining the levels of vitamin C in the extract, the extract solution was made with a concentration of 1000 ppm which was determined by UV-Vis spectrophotometry, showing that the levels of vitamin C in the extract of red dragon fruit (Hylocereus polyrhizus) had an average vitamin C content of 31.413 mg/100g. In the antioxidant activity test of the extract solution, various concentrations were made, namely 50 ppm, 100 ppm, 150 ppm, 200 ppm and 250 ppm, the average percentage of antioxidant activity was 19,859

Abstract

Chayote and green beans are classified as plants that contain various vitamins. Vitamins in the human body can function as antioxidants and metabolic regulators. Management of chayote and green beans into flour is still not implemented. This study aims to determine the levels of vitamins A, C and E contained in biscuits from the formulation of chayote flour and mung bean flour. Determination of levels of vitamins A, C and E in biscuits using UV-Vis spectrophotometric method. The results of this study indicate that biscuits with a ratio of 0:100% (0:200 grams) contain 0.0063 mg/100g of vitamin A, 12.740 mg/100g of vitamin C and 0.0026 mg/100g of vitamin E; a ratio of 25:75% (50:150 grams) containing 0.0044 mg/100g of vitamin A, 13,406 mg/100g of vitamin C and 0.0019 mg/100g of vitamin E; a ratio of 50:50% (100:100 grams) containing 0.0038 mg/100g of vitamin A, 14,826 mg/100g of vitamin C and 0.0033 mg/100g of vitamin E; a ratio of 75:25% (150:50 grams) containing 0.0071 mg/100g of vitamin A, 15.397 mg/100g of vitamin C and 0.0040 mg/100g of vitamin E; the ratio of 100:0% (20:0 gram) contains 0.0046 mg/100g of vitamin A, 14,258 mg/100g of vitamin C and 0.0039 mg/100g of vitamin E.

Abstract

Problem Based-Learning (PBL) is often contrasted with the conventional learning and to modified technical and strategic of learning based-on problem in the classroom. Since it used to discovery and modified learning routine educators or teacher in the past ten years (Cifti, 2015; Nur Jannah, 2014; Ananth & Rusiyanto, 2012; Susanti, E., Ritonga, M., & Bambang, B., 2020; Minardi, J., & Akbar, A. S., 2020). Research by Susanti, E., Ritonga, M., & Bambang, B., 2020; Minardi, J., & Akbar, A. S., 2020 stated that the Problem Based-Learning is significantly and good proof able to increase the attention and the interest of student in active learning. However, the use of Problem Based-Learning by the teacher as a learning agent becomes ineffective if the student were not interested in the problems to be solved in the class. Therefore, it takes strategic and technical of learning by the role of instructional media to stimulate student interest. The Technical and strategic use media which could be integrated in learning media above, Power Point is selected and issued could to increase, motivate, support the model of Problem Based-Learning (PBL). Problem Based-Learning (PBL) is learning of media can appropriate media to focus and alternative media to address these issues.

Abstract

Lack of student learning motivation results in students being less able to understand basic science concepts, so the quality of science education tends to be low. The purpose of this study was to determine the effect of the guided inquiry learning model on critical thinking skills and science learning outcomes in the experimental and control groups. The sample in this study consisted of 50 students. The data analysis technique used is descriptive statistical approach, N-Gain, and simple linear regression. The results showed that based on the data management hypothesis, it was obtained that there was an influence of the guided inquiry learning model on students' critical thinking skills. In addition, the N-Gain results show that as many as 24 students from the experimental class have increased critical thinking skills in the high category, while in the control class, only 10 students have increased critical thinking skills in the high category. The experimental class students' science learning outcomes showed that 20 students were in the high category and only 12 students from the control class were in the high category. So it can be concluded that guided inquiry in the field of science studies affects critical thinking skills and science learning outcomes for fifth grade students of UPTD SD Negeri 18 Barru, Barru Regency.
