Abstract

Numerous variables, such as drought period, growth stage, and varieties, influence rice growth and yield in response to drought. This study was conducted to determine the effect of drought periods on the growth and yields of several rice lines and varieties as well as to select drought-tolerant lines. Using a split-plot design with three replications, the pot experiment was carried out in the greenhouse from December 2015 to April 2016 at the Sukamandi Experimental Site of Indonesian Center for Rice Research (BB Padi). Drought periods were treated as the main-plot, while the rice lines/varieties were treated as sub-plots. The main-plot consists of four levels: control, drought at the maximum tillering stage, drought at the primordia stage, and drought at the grain filling stage. The rice lines used are expand lines of rainfed lowland rice and upland rice from the BB Padi breeding program. The results showed that of the 36 rice lines and 6 varieties tested, drought periods during maximum tillering and primordia affected plant height, while the tiller number was not affected by all drought periods. From the yield characters, drought periods increased unfilled grain percentage and decreased 1000 grains weight and also grain weight per plant. Jatiluhur is consistently tolerant and has the highest yield. There are 8 rice lines with consistent tolerance and not significantly different yields with Jatiluhur: B13650E-TB-80-2, B14168E-MR-6, B14168E-MR-10, B14168E-MR-11, B14168E-MR-12, B14168E-MR-13, B12480D-MR-7-1-1, and B12056F-TB-1-29-1. Keywords:  Drought periods, Rice lines,  Growth, Yield

Abstract

Optimalisasi penggunaan lahan rawa pasang surut untuk meningkatkan produktivitas dan hasil padi dapat dilakukan dengan peningkatan indeks pertanaman (IP). Penelitian ini dilakukan untuk mendapatkan informasi peluang peningkatan indeks pertanaman melalui penggunaan varietas unggul baru padi. Penelitian dilaksanakan pada Januari-Desember 2019 di Desa Sukaraja, Kabupaten Banyuasin, Sumatera Selatan dengan menguji tiga kombinasi pola tanam yang diulang empat kali. Perlakuan pola tanam yaitu: P1: Regas (musim tanam /MT 1)-Regas (MT 2); P2: Inpara 2 (MT 1)-Inpara 2 (MT 2); P3: Inpara 2 (MT 1)-Inpari 19 (MT 2)-Inpari 19 (MT 3). Regas adalah varietas lokal yang umum ditanam petani, Inpara 2 adalah varietas unggul baru (VUB) adaptif lahan rawa, dan Inpari 19 adalah VUB berumur genjah. Budidaya yang diterapkan yaitu Rawa Pasang Surut Intensif, Super, dan Aktual (RAISA). Pengamatan dilakukan terhadap karakter pertumbuhan dan hasil, serta perbandingan hasil antar pola tanam. Pola tanam padi-padi dengan VUB adaptif rawa (Inpara 2) merupakan pola tanam dengan hasil tertinggi sebesar 11.35 ton ha-1 GKG atau 34.6% lebih tinggi dibanding padi lokal. Indeks pertanaman di lahan rawa pasang surut berpeluang ditingkatkan menjadi tiga kali tanam pada kondisi curah hujan tahunan tinggi dengan didukung pendekatan varietas hasil tinggi dan umur pendek. Kata kunci: budidaya lahan rawa, optimalisasi lahan, padi rawa, pola tanam, RAISA

Abstract

The focus of this research is to determine PPG teachers' perceptions of the integration of TPACK in Indonesian language learning. There are seven known components in TPACK that must be mastered by teachers, namely CK (Content Knowledge), TK (Technological Knowledge), PK (Pedagogical Knowledge), PCK (Pedagogical Content Knowledge), TCK (Technological Content Knowledge), TPK (Technological Pedagogical Knowledge) and TPACK (Technological Pedagogical Content Knowledge). The data collection technique was through a closed questionnaire with a sample size of 30 PPG Daljab category 1 class 3 teachers. Researchers used a Likert scale in their research with intervals of 1-4. Research data was analyzed using quantitative analysis. The results of this research are displayed through percentages. The results of the research conducted show that PPG teachers have a good perception of the implementation of TPACK in Indonesian language learning. The CK component is 82% in the very good category, the TK component is 76% in the good category, the PK component is 79% in the good category, the PCK component is 79% in the good category, the TCK component is 70% in the good category, the TPK component is 78 % in the good category, and the TPACK component is 74% in the good category.
