Abstract

One of Freshwater Biology course problems is that the students were unable to understand the environmental phenomena around them. The aim of this study was to develop issue-based teaching materials in Freshwater Biology course to improve the students’ understanding about the environmental phenomena through their learning outcomes. This research and development used three phases of the 4D model developed by Thiagarajan, namely define, design, and development. The development results were validated by content and media experts. The design used for pilot test, which was conducted among 20 students, was one group pretest-posttest design; meanwhile the data analysis technique used was independent t-test. It can be concluded that the teaching materials developed was valid with the average validation score as high as 79.83%. In addition, there was significant improvement (sig. 0.000) of student learning outcomes after attending the course which implementing the issue-based teaching materials developed. Thus, the implementation of issue-based teaching materials is recommended in Freshwater Biology course due to its potential in improving students’ learning outcomes.

Abstract

This research aims to examine the effectiveness of concept maps as learning strategy and as an evaluation tools to assess students’ mastery of concepts. The sample in this study was students of grade IX in one of Junior High School in Bandung by using Pretest-Posttest Randomized Control Group Design. The subject learned was excretory system. In experimental group, the students were taught by using concept map strategy, whereas the students in control group were taught by using elaboration strategy that is taking notes. The method used in both classes were lecture and discussion. The effectiveness of concept map as a learning strategy was measured by using N-Gain value. Meanwhile, the effectiveness of concept map as an evaluation tool to assess students’ concepts mastery was seen from the relationship between students’ score in multiple-choice evaluation and the score of concept map evaluation based on class clasification from multiple choice score: upper class, middle class, and lower class. The result shows that the N-Gain in experimental group (0,73) is greater than N-Gain in control group (0,62). The effectiveness of concept maps as an evaluation tool is quite effective because otherwise the results showed that students' grades multiple-choice acquisition value is directly proportional to students in making a concept map. It can be conclude that concept maps can be used as a learning strategy as well as an evaluation tool. Keywords: concept map, learning strategy, evaluation tools, concept mastery, excretory system

Abstract

Kangkung darat (Ipomoea reptans. Poir) termasuk  ke dalam tanaman hortikultura yang mudah dibudidayakan. Namun, kangkung perlu diberi asupan nutrisi yang cukup dengan pupuk yang tepat untuk memperoleh pertumbuhan dan hasil yang tinggi. Penelitian ini bertujuan untuk mengungkap pengaruh perbedaan asimilasi zat nitrogen pupuk organik dan pupuk non organik (ZA) erhadap pertumbuhan dan gangguan fisiologi pada tanaman kangkung darat (Ipomoea reptans. Poir). Penelitian dilaksanakan di Bandung Raya selama dua pekan. Metode yang digunakan dalam penelitian ini adalah penelitian eksperimental dengan pendekatan metode deskriptif kuantitatif. Perlakuan dalam penelitian ini yaitu pengaruh perbedaan komposisi pupuk ZA (Z0=0 gram, Z1=0,25 gram, Z2=0,5 gram, Z3=0,75 gram) dan komposisi pupuk organik (O0=0 mL, O1= 55,25 mL, O2= 110,5 mL, O3=165,75 mL) terhadap tinggi tanaman dan panjang daun dari hari pertama sampai hari ketujuh. Selain itu juga diamati kemunculan gangguan fisiologi seperti kelayuan, klorosis dan nekrosis. Pengelolaan data dilakukan dengan menggunakan teknik statistik deskriptif. Analisis data dilakukan melalui uji One-way Anova. Hasil penelitian menunjukkan bahwa tanaman kangkung yang diberi pupuk non organik (ZA) mengalami rata-rata pertumbuhan lebih tinggi 5,7 cm dibandingkan yang diberi pupuk organik serta terdapat beberapa gangguan fisiologis pada tanaman kangkung yang diberi perlakuan pupuk organik berupa nekrosis dan klorosis.

Abstract

Kedelai merupakan salah satu komoditas yang memiliki nilai konsumsi tinggi di Indonesia, tetapi memiliki nilai produktivitas yang rendah. Beberapa bulan lalu, disinyalir sempat terjadi kenaikan harga kedelai impor yang berdampak pada terjadinya fluktuasi harga kedelai di domestik dan hasil produk olahannya seperti tahu dan tempe. Maka, perlu solusi untuk mengatasi permasalahan tersebut, salah satunya adalah dengan dilakukannya percobaan yang diprediksi dapat meningkatkan daya tumbuh tanaman kacang kedelai yaitu dengan pemberian tambahan nutrisi yang terdapat pada air cucian beras merah dan putih. Air cucian beras merupakan salah satu limbah yang tidak memiliki nilai ekonomis dan seringkali dibuang tanpa dimanfaatkan kembali. Dalam rangka untuk meningkatkan produktivitas kedelai di Indonesia sekaligus dalam rangka memanfaatkan limbah air cucian beras, penelitian mengenai pengaruh pemberian air cucian beras terhadap laju imbibisi serta perkecambahan biji kedelai ini pun dilakukan. Penelitian dilakukan dengan membuat air cucian beras putih dan beras merah dalam konsentrasi 25%, 50%, 75%, dan 100%. Perendaman dan perhitungan berat biji kedelai dilakukan pada interval waktu 2, 4, 8, 16, dan 24 jam untuk menelusuri pengaruh dari air cucian beras terhadap laju imbibisi dan membandingkan antara pengaruh larutan cucian beras putih, beras merah, dan juga kontrol terhadap perkecambahan sebagai output keberhasilan imbibisi. Setelah diuji secara statistik ternyata tidak ada perbedaan yang signifikan antara berbagai konsentrasi air cucian beras putih dan beras merah terhadap laju imbibisi. Adapun untuk perkecambahan, kontrol diketahui memiliki rata-rata jumlah biji yang berkecambah lebih banyak dibanding perlakuan lainnya dan tidak ada perbedaan yang signifikan antara kontrol dengan perlakuan-perlakuan lainnya.

Abstract

The allelopathic substances are organic agents which are produced and released by a plant that cause alteration on the neighboring plants. The characteristics of allelochemicals usually inhibit germination of other species and sometime will reduce growth of the other species which associate with the producer of allelochemicals. The mechanism of allelochemicals can be used to suppress a germination of Echinochloa colonum L. and Amaranthus viridis L. These plants are weeds species of rice. The aims of this research were to study the allelochemicals effect from the leaf of pines (Pinus merkusii Jungh. et de Vriese) on germination of Echinochloa colonum L. and Amaranthus viridis L.. The experimental design used Completely Randomized Design with five replicates for each concentration (0, 250, 500, 750, 1000 ppm). The result which was analyzed with One-Way Analyze of Varians (ANOVA) indicated that giving a pine leaf extracts had an inhibitor effect on germination of E. colonum L. and A. viridis L. Keywords: Pinus merkusii Jungh. et de Vriese, allelopathy, weeds, Echinochloa colonum L., Amaranthus viridis L. References
