Abstract

This study aims to determine the effect of the Quantum Learning Model on the Science Learning outcomes of students in Class 1V at SDN 3 Pijot. 2019/2020 Academic Year. with a sample of 32 students from class IVa and 30 class 1Vb. This type of research uses a quasi-experimental design in the form of a control group pretest-posttest design. The research instrument used a multiple choice test. How to collect data using pretest and posttest and analyzed using Product moment correlation test. After comparing the results of the pretest and post-test data, the results showed that there was an increase in student learning outcomes and performance, namely 17.7% with a correlation test obtained t-count = 3.348 and t-table = 1.671 at the use of the 99% confidence interval level with the coefficient of influence including the very high category. So the conclusion is that there is an influence of the Quantum Learning Learning Model on the Science Learning Results of Students Class 1V at SDN 3 Pijot. 2019/2020 Academic Year

Abstract

This study aimed to evaluate the effects of raising laying hens in intensive cage and various free-range systems on hen-day production (HDP), egg weight, egg mass, yolk cholesterol, and yolk protein content. A total of 80 Isa Brown laying hens, aged 15 weeks and with an average starting weight of 1.20 kg, were assigned to four different rearing treatments: P1 (intensive cage system), P2 (continuous free-range system), P3 (rotational free-range system with two relocations), and P4 (rotational free-range system with four relocations), each with four replicates. Data were analyzed using analysis of variance (ANOVA), and significant differences (P0.05) among treatments were further evaluated using Duncan's multiple range test. The results showed that the rearing system significantly influenced daily body weight gain (DBWG), daily feed intake (DFI), HDP, egg weight, egg mass, feed conversion ratio (FCR), and yolk cholesterol content (P0.05), but had no significant effect on yolk protein content (P0.05). In conclusion, continuous free-range systems led to higher HDP and egg mass, while the intensive cage system resulted in greater egg and body weight, along with higher feed intake. The continuous free-range system was associated with a lower FCR, and the rotational free-range system with four relocations yielded the lowest yolk cholesterol levels.
