Abstract

Penelitian bertujuan untuk mengetahui kualitas soal secara kuantitatif pada materi pemanasan global kelas VII SMP Negeri 2 Lembah Gumanti Kabupaten Solok. Soal yang di analisis sebanyak 41 soal objektif yang dianalisis secara kuantitatif meliputi validitas, reliabilitas, daya pembeda dan tingkat kesukaran soal. Hasil analisis soal menunjukkan nilai validitas dan reliabilitas sangat tinggi. Indeks kesukaran soal kategori cukup (75,61%), terlalu sukar (17,10%), terlalu mudah (7,32%). Analisis daya pembeda soal didapatkan 2 buah soal dengan kriteria jelek sekali (4,88%), 11 soal (26,83% jelek), 21 soal (51,2%) sedang dan 7 soal (17,07% baik). Hasil penelitian menunjukkan analisis kuantitatif meliputi validitas dan reliabilitas, telah memenuhi kriteria soal yang baik. Indeks kesukaran soal memiliki kriteria cukup dan sesuai dengan tujuan pembelajaran dan daya beda soal memiliki kriteria sedang yang berarti soal sudah dapat digunakan sebagai pembeda siswa yang berkemampuan tinggi, sedang dan rendah.

Abstract

Penelitian bertujuan untuk mengetahui hubungan gaya belajar visual terhadap hasil belajar mahasiswa. Penelitian ini merupakan penelitian kualitatif deskriptif. Populasi dan sampel penelitian adalah mahasiswa angkatan 2017 dengan jumlah populasi 64 mahasiswa dengan menggunakan teknik total sampling. Instrumen penelitian berupa angket sebanyak 14 butir pernyataan. Teknik analisis data dalam penelitian yaitu menghitung persentase indikator angket serta analisis korelasi product moment. Analisis data dilakukan membandingkan nilai thitung > ttabel pada taraf 0,05. Hasil penelitian menunjukkan nilai thitung < ttabel maka Ho diterima, artinya gaya belajar visual terhadap hasil belajar mahasiswa tidak memiliki hubungan yang signifikan. Berdasarkan hasil penelitian disimpulkan bahwa terdapat hubungan yang signifikan antara gaya belajar visual terhadap hasil belajar mahasiswa dengan korelasi sangat rendah.

Abstract

Penelitian ini bertujuan untuk mengetahui kualitas air  sungai di hutan Sumatera Utara ditinjau  dari  segi  mikrobiologi  perairan. Pengambilan  sampel  dilakukan  di  tiga  titik  pada  lokasi yaitu sungai dekat hutan, sungai dekat pemukiman masyarakat, dan sungai dekat pertanian.  Uji kandungan mikrobiologi dilaksanakan  di  Laboratorium  Manajemen  Pengelolaan  Sumberdaya  Perairan dengan menggunakan metode seri tabung 3-3-3. Hasil penelitian menunjukkan bahwa bakteri yang ditemukan pada sungai di hutan Sumatera Utara adalah bakteri coliform fecal dengan jumlah pada titik 1 (1360/100 ml), titik 2 (1580/100 ml), titik 3 (1210/100 ml). Kualitas air Sungai di hutan Sumatera Utara tidak memenuhi baku mutu air karena kandungan bakteri fecal coliform berada di atas baku mutu 1000/100 ml.

Abstract

Penelitian ini bertujuan untuk menelaah peningkatan pembelajaran field trip dengan strategi terfokus dan setengah fokus pada keterampilan berpikir kritis siswa pada materi ekosistem. Metode penelitian yang digunakan adalah kuasi eksperimental dengan desain penelitian pre-and posttest yang melibatkan 28 siswa dari dua kelompok10 jenjang SMA sebagai sampel penelitian yang dipilih menggunakan cluster random sampling dibagi menjadi dua kelompok penelitian (kelompok eksperimen dan kelompok pembanding). Pengumpulan data dilakukan melalui tes soal keterampilan berpikir kritis sebelum (pretest) dan sesudah perlakuan (posttest). Data penelitian dianalisis secara deskriptif kualitatif dan kuantitatif menggunakan statistik deskriptif dan gain ternormalisasi. Hasil penelitian menunjukkan bahwa keterampilan berpikir kritis meningkat secara moderat, baik pada kelompok eksperimen maupun kelompok pembanding. Disimpulkan bahwa pembelajaran field trip berbasis strategi terfokus dan terfokus sedangmampu menstimulasi peningkatan keterampilan berpikir kritis siswa pada materi ekosistem.

Abstract

The study aims to determine the validity of biotechnology modules containing research results for biology students. This is a design and development research project with the Plomp model development. The type of data in this study consisted of qualitative data obtained from the module validation sheet with a Likert Scale. The validation sheets in the form of questionnaires were given to the validators, who are experts on content, media, and linguistics. The aspects assessed in the validation sheets were all very valid, with values of 3.5, 3.8, 3.7, and 3.7 for content eligibility, presentation, linguistic, and graphic components, respectively. The mean score of the validity test was 3.7, which was in the category of very valid. It can be concluded that the study can be continued to the next level of the Plomp development model.

Abstract

Abstract. Fern is a plant that is spread so widely that it can be found from the lowlands to the highlands, has a high diversity of Indonesian flora groups and many grow in moist areas such as oil palm plantations, forests, hills and even river flows. In the river there are fern plants that grow attached to the stone. The study was conducted in July-August 2019 and aims to find out the types of fern plants that are used as decorative plants by sociality. The method used in this study is a descriptive survey by field observation and direct collection. Collections obtained were identified using with plant taxonomy books and field guides. Analysis of research data was done descriptively. The results showed that there were 6 types of decorative fern plants consisting of 1 class, 1 nation, 5 tribes, and 6 clans.Keywords: Pteridophyta, The Benefits of Fern

Abstract

Learning media plays an important role in learning outcomes. This study aims to determine the feasibility of the developed of preserved- leaves media. This type of research is research and development with the Dick and Carey Models. The research started from the phase of needs analysis, development, design, implementation, validation and product testing. Data were collected using scala likert, processed using the percentage formula  and analyzed descriptively. The test results on the product are very valid for the theory aspect (88.75%) and media aspect (83.67%), very practical (score 81.67% on the aspects of interest and ease to use), and very feasible (score 86, 25% for the small group test and 90.50% for the large group test). Thus,  concluded that the preserved-leaves media is valid, practical and feasible to use for plant morphology course.

Abstract

This study aims to describe learning styles and their relationship to biology learning outcomes for students of class XI IPA Madrasah Aliyah Negeri (MAN) in the era of covid-19. This type of research is descriptive quantitative research. The learning styles studied include visual, auditory and kinesthetic learning styles. Sampling was done by total sampling with a total sample of 68 students of class XI IPA. The research instrument was a questionnaire on the types of student learning styles that were valid and reliable. The results of the validity test of the questionnaire by two validators were 3.25 and 3.00, respectively, with a valid and appropriate category for use, and the results of the questionnaire reliability test were obtained at 0.66 with a fairly high interpretation. The results showed that the overall student learning style was kinesthetic by 41%; auditory 30% and visual 29%, the highest learning style is kinesthetic. There is a positive relationship between learning styles and student biology learning outcomes. It can be concluded that the higher the percentage of learning styles, the higher the students biology learning outcomes. The results of this study provide information to teachers to use appropriate and varied strategies and methods as well as learning media during the learning process.
