Abstract

Science learning requires direct experience in order to develop the ability to explore and understand the natural surroundings scientifically. So far in elementary school at Bukittinggi, the process of learning science only memorizes facts, principles or theories. In science learning, students are not involved in finding or applying their own ideas and they do not instill the values contained in the learning. The science learning process in classroom is not yet fully in accordance with the demands of the curriculum. The teacher provides more material in the textbook without relating it to students' daily problems that are in accordance with the material, thus causing less interesting in learning. The teacher also has not actively involved all students in learning and emphasizes learning only on students who are smarter. The purpose of this study was to increase the activity and learning outcomes of science learning by using a problem-based learning model in SDN 11 Aur Kuning Bukittinggi, West Sumatra. This classroom action research was conducted in 2 cycles with the research subjects of grade IV students with totalling 25 people. The research data were collected through observation and tests. The effectiveness of actions in each cycle from the results of observations and tests is described and then reflected to take corrective action in the next cycle. In science learning, students' learning activities were observed, namely: visual activities, oral activities, writing activities, motoric activities and emotional activities. The research findings show that the problem-based learning model can increase student activity and learning outcomes.

Abstract

Although research on student scientific creativity can be found easily on the literature, it is difficult to get articles on how scientific creativity is presented for some decades. This article report scientific creativity from 1960 to 2022 which mined from Scopus database. 181 articles were analyzed using a bibliometric analysis. Publish or Perish (PoP), Mendeley and Vos Viewer were used to find the map of literature on scientific creativity. Keyword used in this research was merely “Scientific Creativity”. The results of the analysis using Vos Viewer show some interesting findings. First, although there have been publications published since 1960 on scientific creativity, from 2008 to 2022 the number of studies on this topic increased significantly. This may be due to the increasing attention of researchers to 21st century skills, creativity and other skills. Second, several findings from Vos Viewer show that there is no collaboration among researchers on scientific creativity that should be able to improve the quality and productivity of research around the topic. Third, the topics about the model and the effectiveness of scientific creativity are increasing. This matter can be taken into consideration by researchers to be used as the next research.

Abstract

Refill Drinking Water Depots (DAMIU) in the community are easy to find at affordable prices, which is a concern in the feasibility of refill drinking water quality. E.coli is one of the pathogenic bacteria present in drinking water that has poor quality. When it enters the body it can cause symptoms of diarrhea, fever, vomiting and others. The purpose of this study was to create a specific primer for E.coli that can be used to detect E.coli and determine the optimum temperature of primer annealing. Researchers do a new primer design because the existing design does not necessarily produce the same results due to various factors of different experimental conditions. The primer design was carried out on an in silico-based and had to meet the criteria for a good primer because it would be used in vitro. E.coli gene sequences was aligned with Shigella sp. using Pairwise Alignment. Primer candidates were analyzed using NCBI's Primer3 and Geneious Prime tools. The result is that the first primer pair is forward 5'–ATGCAGTGGTTCCTTATCTCACA-3' reverse 5'- ATCCTTAATGGCACTGCGCT-3', amplifying the amplicons along 417 bp in the yraJ gene. The second primer pair, forward 5'-CAGAACGTTTTTCATTCAGCAGG-3' reverse 5'-GCCACTACCAGATCGAGTCA-3' amplifies the 573 bp amplicon in the rne gene. The optimum annealing temperature for both pairs of primers was 59.5oC.

Abstract

Induksi poliploid merupakan suatu bentuk mutasi buatan yang dilakukan untuk meningkatkan jumlah suatu set kromosom pada suatu organisme. Induksi poliploid ini dapat dilakukan secara alami atau buatan salah satunya yang sering digunakan yaitu kolkisin. Kolkisin merupakan senyawa alkaloid yang dihasilkan dari umbi tanaman krokos (Colchium autumnaatale). Induksi poliploid dengan pemberian kolkisin sudah banyak dilakukan. Pada penelitian ini kolkisin diaplikasikan pada tanaman labu Siam (Sechium edule (Jacq.) Swartz) yang umumnya digunakan sebagai sayuran dan telah lama dimanfaatkan sebagai obat diantaranya sebagai penurun tekanan darah dan memiliki efek diuretik. Penelitian ini bertujuan untuk mengetahui induksi poliploid dapat dilakukan pada tanaman labu siam dan berapa konsentrasi optimum yang diperlukan untuk induksi poliploid tersebut. Penelitian ini adalah jenis penelitian eksperimen menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan pemberian kolkisin (kontrol, 0,01%; 0,02% dan 0,05%). Sampel sesuai perlakuan diameter batang, lebar daun dan panjang daun diamati pada minggu ke empat. Data dianalisi dengan analisis sidik ragam (ANOVA) pada taraf 5%. Pemberian kolkisin mempengaruhi diameter batang, lebar daun dan panjang daun. Pertumbuhan terbaik ditemukan pada pemberian kolkisin 0,02% yaitu diameter batang (1,4 cm), lebar daun (11,4 cm) dan panjang daun (11,1 cm). Disimpulkan bahwa induksi poliploid dapat dilakukan pada labu siam dengan konsentrasi 0,02%.
