Abstract

Mind Map The sophistication of information technology and internet network in the fourth industrial revolutionera can be utilized to supportthe learning process. Electronic learning (E-learning) is an innovative learning method that is appropriate in answering the challenges of the fourth industrial revolution era. E-learning is a way to enrich education by integrating technology into traditional classrooms. E-learning allows lecturers to share syllabus and learning material to students, provide assignments that must be done by students and assess students in real-time. This study aims to analyze the response of Biology students to the use of e-learning in ethnobotany courses. The study was conducted from June to October 2019. The subjects of this study were students of Biology Study Program, Class A and Class B year 2016. The research method used was descriptive method using survey methods. The instrument used was a student response questionnaire. The results of the assessment of student responses obtained a value in the learning aspect of 85.10% with a very good category, a material aspect of 89.71% with a very positive category, a programming aspect of 82.46% with a very positive category, and multimedia aspect of 88.17% with a very positive category.

Abstract

 The aim of this study to determine: a) the consentration of carbon monoxide in the air in District Medan Sunggal, b) the relationship between traffic density and the concentration of CO (Carbon Monoxide) in Medan Sunggal, c) is there the relationship between the condition of physical and chemical environment on the concentration CO in Medan Sunggal. This study was conducted in December 2013- February 2014 in the three location, they are: 1) Jl. Arten Ringroad, 2) Jl. TB Simatupang, 3) Jl. Setia Budi, air analysis performed in BTKL PP Medan. The design of this study using the pearson product moment correlation. The parameter measured were the number of level of CO, the physical-ehemical properties and the totality of traffic density. The research findings indicated that: the highest level of CO was in Jl. Setia Budi with 17 ppm while in the Jl. TB Simatupang was 11 ppm and in the Jl. Arten Ringroad 8 ppm. There is a significant relationship between traffic density with the content of CO levels with the value r=0,9. The correlation is very high, the correlation is positive significant. By counting using the pearson product moment analysis was obtained tcont (5,4)  ≥  t table(1,895). There is relationship between traffic density and the levels of CO in the air. While the dampness and wind speed on the consentration of CO is found negative correlation. The correlation of temperature on the concentration of CO is r=0,9, but there is not significant correlation by t hitung(2,1)  ≤ dari  t tabel (6,314).

Abstract

Book development is very important to do support the learning process because it is integrated with the competencies that must be mastered and learned by students. The first step before developing the book is to conduct a needs analysis. This activity aims to determine the level of student need for the availability of books as learning resources used during ethnobotany lectures on ethnomedicine material. This research was conducted on 35 student of biology at the State University of Medan. This research is a qualitative descriptive study using a survey method. Data collection was carried out using a closed questionnaire. The results showed that the analysis of learning materials, as many as 62.9% of respondents said that ethnomedicine is one of the difficult materials in ethnobotany courses. The highest percentage is when identifying plants used as medicine (54.3%). Based on the needs analysis, 54.3% of respondents needed ethnomedicine books to add insight, so that 51.4% of respondents strongly agreed to develop ethnomedicine books as learning resources. It can be concluded that it is necessary to develop an ethnomedicine book as a learning resource that is prepared based on student needs and adapted to the sub-CPMK of ethnobotany subjects on ethnomedicine material. This research is useful to determine the need for learning resources needed to overcome the problems faced by students in learning activities so that the products developed are in accordance with the needs of students.

Abstract

Lichen is an organism that has a high level of biodiversity and contains secondary metabolites. This study aims to determine the secondary metabolites of lichen extract Usnea sp. on Pine. Qualitative descriptive research method. Preparation of Usnea sp. extract. carried out by maceration method using 96% ethanol (1:10) for 5 days. The results of the study based on the phytochemical screening of the ethanol extract of lichen Usnea sp. contains alkaloids, flavonoids, saponins and tannins and triterpenoids. The results of the phytochemical screening showed a positive (+) result indicated by a change in color or the formation of a precipitate or the formation of foam after adding reagents to the test extract. Meanwhile, a negative result (-) is indicated by the absence of a change in color or the formation of precipitate or the formation of foam after adding reagents to the test extract.

Abstract

According to observations on the Lower-Level Organisms Taxonomy course, it showed that the questions used in the course have not been presented at the higher-order thinking skill (HOTS) level. HOTS-based questions are one of the assessments in the cognitive domain that function to train HOTS and solve complex problems well. Moreover, it can train critical thinking skills as one aspect of the skills needed in the 21st century. Therefore, this study aims to develop HOTS-based questions on Monera topic to improve students' critical thinking skills. The research was conducted from January to February 2022. Development was carried out using ADDIE approach. Data collection techniques were carried out through the questionnaires and validation instruments by expert validators. The data were analyzed in two ways, namely content validity and construct validity. The results showed that the validity of the questions by expert validators was categorized as very good. Meanwhile, empirical validity shows that there were 10 questions declared valid from a total of 20 questions. The results of reliability test were 0.780 valid with a high interpretation. The test of difficulty level results showed that there were 8 moderate questions and 2 difficult questions. The results of differentiating power test showed that there were 1 very good question, 6 good questions, 2 sufficient questions and 1 weak question. Thus, it can be concluded that from a total of 20 HOTS-based questions that were developed only 10 questions were declared empirically feasible to improve students' critical thinking skills on Monera topic. It is recommended to use these questions in Lower-Level Organisms Taxonomy lectures.

Melatih dan mengembangkan kemampuan berpikir kritis sangat penting bagi siswa untuk mendapatkan hasil belajar yang optimal. Salah satu strategi yang dapat dilakukan guru dalam melatih dan meningkatkan kemampuan berpikir kritis siswa adalah dengan mengembangkan bahan ajar berupa modul berbasis inkuiri. Penelitian ini secara umum bertujuan untuk menghasilkan modul berbasis inkuiri pada materi ekosistem yang layak, praktis dan efektif dalam meningkatkan kemampuan berpikir kritis siswa di kelas X SMA. Penelitian ini termasuk jenis penelitian pengembangan menggunakan model ADDIE. Subjek penelitian adalah siswa kelas X SMA Negeri 3 Tebing Tinggi sebanyak 2 kelas terdiri dari kelas eksperimen (34 siswa) dan kelas kontrol (34 siswa). Data penelitian dikumpulkan melalui lembar validasi ahli, lembar observasi, lembar angket serta instrumen tes kemampuan berpikir kritis. Teknik analisis data yang digunakan meliputi analisis kelayakan, analisis kepraktisan dan analisis keefektifan modul dengan pendekatan independent sampel t-test. Hasil penelitian menunjukkan bahwa modul berbasis inkuiri pada materi ekosistem kelas X SMA telah memenuhi kriteria sangat layak berdasarkan penilaian tim validator ahli materi (85,1%) maupun penilaian tim validator ahli media/desain (94,0%); memenuhi kriteria sangat praktis berdasarkan hasil pengamatan aktivitas guru (89,0%) dan aktivitas siswa (83,8%); serta efektif diterapkan untuk meningkatkan kemampuan berpikir kritis siswa yang dibuktikan dari persentase ketuntasan belajar klasikal siswa kelas eksperimen yang mencapai 97,1% serta pengujian secara statistik dengan nilai thitung > thitung (4,945 > 1,665) dan nilai probabilitas sebesar 0,000 < 0,05. Guru biologi memberikan respon yang sangat baik (86,3%) terhadap modul yang dihasilkan, serta rata-rata siswa juga memberikan respon yang tergolong baik (79,9%)
