Abstract

The Effect of Water Management and Rice Genotypes to Against Toxicity of Iron and Productivity of Rice in Tidal Land Type B in South Sumatera. Tidal land is one of the alternative land to support increased productivity of rice, but rice productivity in this area is still low, and the land utilization is not optimal yet. One factor is high iron content in the soil that can be toxic to plants. The purposes of this study were (1) to determine the effect of water management and rice genotype, as well as their interaction on the percentage of leaf bronzing, growth and yield of rice in tidal lands, (2) to select an alternative combination of water management and rice genotypes that may increase rice yields in tidal land. This study was conducted from February until June 2013 in the tidal area with type B overflow, Mulia Sari village, Banyu Asin regency, South Sumatera. The experimental design used was a split plot design with three replications. The main plot was water management with four levels, while the subplot was rice genotypes consisted of three genotypes. The results showed that water management and its interactions with plant genotypes had significant effect only on the percentage of bronzing, Fe content in shoot, and Fe content in root crops, while the plant genotype significantly affected all observed variables. The use of genotypes tolerant to iron toxicity (Indragiri) combined with (form stagnant and saturated water management) drainage with intervals of two weeks could give yield 6.8 and 6.2 t/ha respectively.Keywords : Water management, genotype paddy, tidal landABSTRAKLahan pasang surut merupakan salah satu lahan alternatif untuk mendukung peningkatan produksi padi, tetapi produksi padi di lahan ini masih rendah, dan pemanfaatan lahannya belum optimal. Salah satu faktor penyebabnya adalah adanya senyawa besi dalam tanah yang dapat meracuni tanaman. Tujuan penelitian ini adalah (1) untuk mengetahui pengaruh pengelolaan air dan genotipe tanaman padi serta interaksinya terhadap hasil padi di lahan pasang surut, (2) memilih alternatif kombinasi pengelolaan air dan genotipe tanaman padi yang sesuai dan dapat meningkatkan hasil padi di lahan pasang surut. Penelitian ini dilaksanakan bulan Februari – Juni 2013 di lahan pasang surut tipe luapan B, Desa Mulia Sari, Kabupaten Banyu Asin Sumatera Selatan. Rancangan yang digunakan adalah Rancangan Petak Terpisah dengan tiga ulangan. Sebagai petak utama adalah pengelolaan air, yang terdiri dari empat taraf, sedangkan sebagai anak petak adalah genotipe padi, yang terdiri dari tiga genotipe (IRH108, IR64 dan Indragiri). Hasil penelitian menunjukkan bahwa pengelolaan air dan interaksinya dengan genotipe tanaman berpengaruh nyata terhadap persentase bronzing, kandungan Fe di tajuk, kandungan Fe di akar dan hasil tanaman sedangkan genotipe tanaman berpengaruh nyata terhadap semua peubah yang diamati. Penanaman genotipe tanaman toleran terhadap keracunan besi (genotipe Indragiri) yang dikombinasikan dengan drainase berinterval dua minggu dapat memberikan hasil masing-masing 6,8 dan 6,2 t/ha.

Abstract

This study aims to improve student learning outcomes in studying Asmaul Husna material by using the Make a Match model combined with an audiovisual learning model. This model was chosen because it can increase student involvement and make it easier for them to understand the concepts in the Asmaul Husna material. This study was conducted in an elementary school with subjects of grade IV students with a total of 22 students, 12 females and 10 males. who have diverse learning abilities. The results of the study indicate that the application of the Make a Match model supported by audiovisual media can improve student motivation, participation, and learning outcomes in the Asmaul Husna material at SDN 1706 Papaso II, Padang Lawas Regency. The Make a Match model is a learning method that invites students to pair up by matching cards or papers that have related information. Students are given cards containing different keywords or concepts, and they must find the right pair of cards based on the information provided. This activity is not only challenging, but also actively involves students in the learning process. In this study, the method used is classroom action research (CAR) with a quantitative approach. Data were collected through observation, learning outcome tests, and interviews to assess the development of students' understanding before and after the implementation of make a match. The results of the study showed that the learning model with the make a match model. showed evidence that it was known that in cycle 1 there were 7 students who had completed learning or around 31.81% while 15 students or 68.18% had not completed it. Then in cycle 2 there was an increase with evidence that children who had completed learning had reached 100% or 15 students in grade IV had all completed it, making cycle 2 the last cycle. The make a match model showed a significant increase in students' understanding of the Asmaul Husna material after using this method in improving students' understanding of the Asmaul Husna material helping students build a better understanding. In addition, students become more active in the learning process and are able to internalize the moral values ​​taught.
