Abstract

Chili is one of the plants that are needed by the community so that proper cultivation techniques are needed, in this case related to fertilization by utilizing organic animal waste.This study aims to determine the response of the growth and production of red chili (Capsicum annum L.) to chicken and cow manure dose combination. The method used is an experimental method with a factorial completely randomized design which consists of two factors, namely the first factor is the type of animal manure which consists of two levels, namely cow dung and chicken manure, the second factor is the dose of fertilizer there are three levels, namely 200 grams, 300 grams and 400 grams. The total combination of treatments was 9 treatments and 3 replications so that in total there were 27 units. The parameters observed were chili growth (height and number of branches) and chili production (number of fruits and fruit weight). The data were analyzed of variance with 5% and 1% levels, followed by Duncan's 5% further test. The results of the analysis showed that the combination of treatments had a very significant effect on plant height and fruit number (12.77 and 5.00), significantly affected the number of fruits (3.55), but did not affect the wet weight of fruit (2.46).Further test results showed that the best treatment for the parameters of plant height, number of branches, and number of fruit was a combination of 300 grams of chicken manure and 200 grams of cow manure. Keywords: dose, chicken manure, cow manure, growth, production

Abstract

The RQA (reading, questioning, and answering) learning model is an active learning model that emphasizes reading, asking, and answering. This study aims to determine the application of reading, questioning, and answering (RQA) learning strategies in improving student learning outcomes in class XI SMA N 6 Kerinci. This research is a type of quantitative research with experimental methods. The research population came from class XI SMA N 6 Kerinci, amounting to 44 people. The sample came from class XI MIPA 2, which amounted to 22 people. The sampling technique in this research is the random sampling technique. Data collection techniques in the form of observation and tests. The test is used to see student learning outcomes using reading, questioning, and answering (RQA) learning strategies. The research instrument is a test in the form of objective questions totalling 30 items carried out for validity, reliability, difficulty index and discriminatory power. Data analysis technique using T-test and N-Gain. The results showed that 1) the results of the study before applying the RQA strategy the highest score of students was 70 and the lowest score was 40 with an average pretest score of 51.59, 2) student learning outcomes after implementing the RQA learning strategy obtained the highest score of 90 and the lowest score of 65 with the result the average posttest is 78.18, 3) there is a significant difference in the application of the RQA strategy in improving student learning outcomes in class XI SMA N 6 Kerinci. Keywords:   Strategy of RQA, Learning Outcomes,
