Abstract

The aim of this study was to identify the difficulties learning by students in the modified free inquiry learning strategy of Molecular Biology and the causes of these difficulties. The method used is descriptive with a questionnaire technique. Respondents are 51 Biology Education students who contracted the Molecular Biology course in Academic Year 2017/2018 at one of the education institution in Kota Pekanbaru. The stages in the modified free inquiry strategy that are carried out consist of steps: 1) orienting students to the topics discussed by giving direct questions, 2) students make questions as the formulation of the problem, 3) proposing hypotheses, 4) collecting data and information for testing hypotheses, 5) communicating findings, and 6) concluding. Topics covered were DNA isolation, agarose gel electrophoresis, and polymerase chain reaction (PCR) and in the lectures were complemented by wet and virtual laboratory activities. Research instruments in the form of a closed questionnaire with answer choices 'yes' and 'no'. Data analyzed are presented in the form of percentage figures. The results of data analysis showed that: (1) Students who experienced difficulty in learning Molecular Biology with a modified free inquiry strategy were 45.10% and those who did not experience difficulties were 54.90%; (2) The causes of difficulties are limited time (78.26%), not finding adequate learning resource materials (39.13%), unable to understand the learning resource materials found (39.13%), unable looking for adequate learning resource materials (21.74%), and not interested in the modified free inquiry strategy (17.39%); and (3) most students agree to apply the modified free inquiry strategy to other biology courses. The implication of the research is the modified free inquiry strategy can be applied in biology learning at the university level.

Abstract

This study aims to determine the effect of interaction and single between the provision of growth regulators BAP and NAA to the proliferation of shoots of tomatoes in vitro. The design used in this research was complete randomized design (RAL). Parameters observed were: shoot age, shoot number, shoot height, percentage of sprout, percentage of roots grow and number of explants forming callus. The data of the observations were analyzed statistically, if F arithmetic was greater than F table, followed by 5% real honest difference test (BNJ). From the results of research interaction giving BAP and NAA have an effect on shoot height (cm) with the best treatment of B1N0 is 6,16. NAA had significant effect on shoot age (day) and shoot height (cm) with best treatment N0 (0 ppm), and root growth percentage with best treatment N3 (1 ppm).Penelitian ini bertujuan untuk mengetahui pengaruh secara interaksi dan tunggal antara pemberian zat pengatur tumbuh BAP dan NAA terhadap perbanyakan tunas pucuk tomat secara in vitro. Rancangan yang digunakan dalam penelitian ini adalah rancangan acak lengkap (RAL). Parameter yang diamati yaitu : umur muncul tunas, jumlah tunas, tinggi tunas, persentase tumbuh tunas, persentase tumbuh akar dan jumlah eksplan yang membentuk kalus. Data hasil pengamatan dianalisis secara statistik, bila F hitung lebih besar dari F tabel, dilanjutkan dengan uji lanjut beda nyata jujur (BNJ) 5 %. Dari hasil penelitian secara interaksi pemberian BAP dan NAA berpengaruh terhadap parameter tinggi tunas (cm) dengan perlakuan tebaik B1N0 yaitu 6,16. NAA berpengaruh nyata terhadap parameter umur muncul tunas (hari) dan tinggi tunas (cm) dengan perlakuan terbaik N0 (0 ppm), dan persentase tumbuh akar dengan perlakuan terbaik N3 (1 ppm).Kata kunci : BAP, In Vitro, NAA, perbanyakan tomat

Abstract

Penelitian ini bertujuan untuk mengetahui profil kesadaran dan strategi metakognitif siswa kelas VII semester ganjil untuk tahun akademik 2014/2015. Pengambilan data dilakukan pada bulan Desember 2014. Penelitian ini merupakan penelitian survei dengan analisis deskriptif. Pengumpulan data menggunakan inventaris, kuesioner, observasi, dokumentasi, dan wawancara. Populasi penelitian ini adalah seluruh siswa kelas VII di kecamatan sekolah menengah negeri Kampar dengan jumlah sampel 409 orang. Hasil penelitian menunjukkan bahwa siswa yang masuk dalam kategori belum berkembang (BB) dan masih belum berkembang (MSB) tidak memiliki (0%). Sejumlah 1,26% siswa masuk kategori kurang berkembang (BBB); 16,91% siswa termasuk dalam kategori mulai tumbuh (MB); 68,23% siswa termasuk kategori dikembangkan dengan baik (SBB atau OK); dan 13,6% siswa masuk dalam kategori tumbuh dengan sangat baik (BSB atau super). Sejumlah 47,28% siswa telah dilatih dalam penggunaan strategi metakognitif dalam pembelajaran. Strategi metakognitif yang digunakan oleh siswa dalam pembelajaran adalah mempersiapkan ringkasan, menggarisbawahi bahan bacaan, dan membuat pertanyaan dan menjawabnya (26,41%); menyiapkan ringkasan dan menggarisbawahi bahan bacaan (18,09%); menyiapkan ringkasan, menggarisbawahi bahan bacaan, membuat peta konsep, dan membuat pertanyaan dan menjawabnya (10,76%), dan menyiapkan ringkasan (10,76%).
