Abstract

Shallot productivity can be increased by taking into account the right fertilizer factor and the potential of the seeds used. The study of potassium and manure dosages and seed size were carried out to get the best treatment in increasing growth and yield. The study was conducted in the Experimental Garden of the Faculty of Agriculture, University of Riau, from February to April 2019, using a divided plot design. The main plot is the difference in seed size (> 5.0 - 7.5 and 2.5 - 5.0) g, subplots of doses of manure (0, 15, 30) ton.ha-1 and children of subplots (0 , 200, 400) kg.ha-1. The parameters observed were plant height, number of leaves, age of harvest, number of tubers per clump, diameter of tuber, tuber fresh weight and tuber dry weight, further tests used BNJ level of 5%. The results showed that the highest dry weight of tubers was obtained in the treatment of large seedlings (> 5.0 - 7.5 g) which were given 30 tons. ha-1 of manure and 400 kg.ha-1 of KCl, with an achievement of 4.1 tons.ha-1.

This was a class action research. The subjects were teachers and students of the fourth grade of SDN 02 Kabawetan. The research instruments were observation sheet and test sheet. The observation data were analyzed using average score formula, highest score, lowest score, score ratio and score range for each criterion. The test data were analyzed using score average formula and percentage of classical completeness. The results showed there was increase of activities and students' grade in thematic teaching using CTL model. These were proven by the score of the first cycle  of teachers' activity which was 28, and increased in the second cycle which was 30,3. Students' score for first cycle  was 9.5 with category of fair and increased in the second cycle  with a score of 12.6 with category of good. The grade for first cycle  of Indonesian Language class showed the average score was 66.2 with classical completeness of 52.94%, there was an increase of grade in the second cycle in which the average score was 78.9 and the classical  completeness was 82.35%. For the Science class, in first cycle  the average score was 69.18 and classical completeness was 58.8%; there was an increase in the second cycle, the average score was 84.28 and classical completeness was 100%. Thus, the application of Contextual Teaching and Learning model could increase activities and students' grade in thematic teaching of the fourth grade of SDN 02 Kabawetan. Keywords : Contextual Teaching and Learning model, learning activities, students' grade
