Abstract

Morphological Characters Diversity of Canna (Canna edulis kerr.) Germplasm. Edible canna (Canna edulis) is the source of potentially of foodstuf. Edible canna have high carbohydrate and nutritions. The starch of edible canna could be exploited as a food materials and industry. Evaluation and characterization were needed to get informations good characters of edible canna for genetic variability to get improved edible canna varieties. Indonesian Center of Agricultural Biotechnology and Genetic Resources and Development ( BB-Biogen) germplasm have two groups edible canna collection , they are red edible canna and white edible canna. The result showed the morphology characters of 27 edible canna accecions were not different on qualitative characters. Such as of 23 white edible canna have not different on qualitative characters. The red edible canna have red color on part of shoot, while in white edible canna have green color. The tuber of red edible canna have pink color and white color of white edible canna. The different are in the flower of white edible canna, there are 17 accecions have yellow color and 6 accecions have orange color. The quantitative characters of flowering, leaf length, leaf width, total leaf and leaf stalk length have low variability(cv <10 %). The character of plant hight, number of tiller per hill and tuber weight per hill have high coeficient variability with range of 14%-21%.

Abstract

Penelitian ini dilaksanakan dengan tujuan (1) Untuk mengetahui penerapan Pembelajaran Kooperatif Tipe Numbered Heads Together (NHT) dalam upaya meningkatkan hasil belajar siswa pada mata pelajaran IPA di Kelas V SDN Mulyasari II Kecamatan Bayonbong Garut. (2) Untuk mengetahui penerapan Pembelajaran Kooperatif Tipe Numbered Heads Together (NHT) yang dapat meningkatkan hasil belajar siswa di Kelas V SDN Mulyasari II Kecamatan Bayongbong Garut. Hal ini berdasarkan fakta permasalahan yang terkait dengan masih kurang memuaskannya hasil belajar IPA yang disebabkan oleh pembelajaran yang masih didominasi oleh guru, metode ceramah masih digunakan untuk meningkatkan hasil belajar siswa. Penelitian ini bersifat penelitian lampangan dalam bentuk Penelitian Tindakan Kelas yang bersifat kolaboratif antara gutu, observer dan kepala sekolah. Penelitian ini terdiri dari tiga siklus, setiap siklus dau pertemuan.Objek penelitian ini adalah siswa kelas V SDN Mulyasari II berjumlah 25 orang. Pengumpulandata penelitian ini adalah dengan cara (1)Observasi, (2) Angket (3) Tes. Dari hasil penelitian yang dilakukan, ternyata penggunaan metode Pembelajaraan Kooperatif Tife Numbered Heads Together (NHT) dapat meningkatkan hasil belajar IPA pada konsep cahaya dan alat optik. Dibuktikan dengan adanya peningkatan nilai hasil belajar siswa kelas V setelah dilaksanakannya pembelajaran dengan menggunakan metode Pembelajaraan Kooperatif Tife Numbered Heads Together (NHT), yaitu dari rata-rata hasil pretest 53,6, rata-rata nilai siklus I 72,4, rata-rata nilai siklus II 76,36 dan rata-rata nilai siklus III 82 Kata kunci : Pembelajaran, Kooperatif, Tipe Numbered Heads Together, Hasil Belajar
