The Use Of The Think Predict Read Connect (Tprc) Strategy And Know Want Learn (Kwl) Strategy In Teaching Reading Comprehension Of Descriptive Text For Seven Grade Students
Get PDFThis study aimed to find out whether there is any difference in the students’ reading comprehension achievement between those who are taught using the Think, Predict, Read, and Connect (TPRC) Strategy and those who are taught using the Know-Want-Learn (K-W-L) Strategy in the seventh grade. This study took place at SMP Negeri 3 Hulu Sungai Tengah. The method used in this study is a quantitative method with a quasi-experimental design. The writer chooses VII B as the experimental class taught using the Think, Predict, Read, and Connect (TPRC) Strategy and VII C as the control class, taught using the Know-Want-Learn (K-W-L) Strategy. Both classes consist of 26 students. The result from the test that the writer got was 62.15 the pre-test score in the experimental class and 62.31 in the control class. The post-test score in the experimental class was 74.08 and 74.15 in the control class. Based on the result of the t-test, it was 0.03, and the t-table was 2.009. The result of the t-test was lower than the t-table, so the hypothesis null was accepted, and the alternative hypothesis was rejected. It means there is no difference in the students’ reading comprehension achievement between those who are taught using the TPRC Strategy and the K-W-L Strategy. The use of the TPRC Strategy and K-W-L Strategy had a positive impact on increasing students’ scores from pre-test to post-test. In other words, both techniques are good for English Language teaching classrooms. Based on the conclusion of the study, the writer suggests that teacher should increase their theoretical knowledge when they are interested in applying both strategies. The teacher could use both strategies to improve students' achievement, especially in reading comprehension. Furthermore, the writer hopes this study can have a beneficial impact on other researchers.

Pengaruh Pemberian Berbagai Macam Bahan Organik terhadap Ketersediaan Hara Nitrogen, Fosfor dan Kalium serta Serapan Nitrogen oleh Jagung (Zea mays L.) pada Tanah Ultisols
No full textUltisols distributes spreadly in Indonesia, but this soil has low fertility. Therefore, the application of organic matter (OM) is a common management to increase this soil fertility. The purpose of this study was to determine the role of different types of OM (originated from animals and plants) on the availability of nitrogen, phosphorus, and potassium as well as nitrogen uptake in maize in Ultisols. Soil with a mass of 5 kg without organic matter (control), with the application of chicken manure, cow manure, swallow manure, kirinyuh, babadotan, and kalopo manure were incubated in experimental pots for two weeks at 60% field capacity. After the completion of the incubation period, soil sub-sampling was carried out for the determination of available N, available P and exchangeable K. Furthermore, in each experimental pot, corn seeds were planted, and the observations of dried-weight of corn and nitrogen uptake in corn were observed in a vegetative phase. The results showed that the application of different types of organic matter increased soil pH, nitrate content, exchangeable K, plant dried-weight and plant nitrogen uptake. The content of ammonium and available P was not affected by OM addition. The results also showed that OM derived from animals resulted in higher increases in pH and exchangeable K than those derived from plants. However, OM derived from plants resulted in higher increases in nitrate, plant dry weight and better plant N uptake than OM from animal waste. The results of this study show that the application of OM results in increases in some soil chemical properties, in which the degree of increases in soil chemical characteristics is controlled by the OM origin

Get PDFPaddy fields for all of Indonesia are 8.1 million ha, about 43% are in Java and about 57% are outside Java. Paddy fields are part of the wetlands. Paddy fields control the global climate through the gases they produce and have a greenhouse effect. One of the greenhouse gases is methane, therefore the purpose of this study was to determine the effect of rice field waste management on methane emissions and the population of methanogenic microorganisms. The research method used is one-factor Completely Randomized Design (RAL). The factor tested was the method of managing rice waste before planting rice with five treatments namely: A = Rice field waste was slashed and then lifted into the mound after a few days of being returned to the field; B = Rice field waste is carried out management slashed, rolled up, reversed, and stretched; C = Rice field waste is slashed, planted with traces and then slashed again after the trace is transferred to land outside the research plot; D = Rice field waste sprayed with herbicide 2 times; E = Ricefield waste sprayed with herbicide 1 time and then soil in the tractor. Each treatment was repeated four times so 20 units of the experimental. CH4 gas retrieval used the hood method while the microorganism population used the MPN (most probable Number) method. The results showed that the rice field waste management method had an effect on methane emissions and populations of methanogen microorganisms in the planting and vegetative phases, while the generative phase had no effect.Paddy fields for all of Indonesia are 8.1 million ha, about 43% are in Java and about 57% are outside Java.
