Abstract

One ofthe way able to be conducted to improve productivity of soy is with treatment of organic fertilizer at different treatment time and dose. This research aim to to know influenceof liquid organic fertilization to soy crop productivity, knowing fertilization time and dose giving best result and also know interaction between fertilization time and dose. Researchconducted with Complete Random Device with factorial pattern . First factor of fertilization dose that is : D0 ( without treatment of manure), D1 ( 0,7 fertilizer ml / 1 water litre), D2 ( 1,4 fertilizer ml / 1 water litre) and D3 ( 2,1 fertilizer ml / 1 water litre). Second factor is time fertilization of T1 ( morning), T2 ( daytime) of T3 ( afternoon). Parameter perceived by hat isamounts of pod wet heavy of pod wet heavy of seed and dry heavy seed. Data to be analysed with ANOVA level of signification 95%, continued by test of Duncan level of signification 95%. Research result indicate that fertilization with liquid organic fertilizer complete can improve soy crop productivity, but difference of passed to dose is crop give result differ do not reality. Fertilization time at afternoon and morning cause compared to higher soy crop productivity in the day time. Fertilization in the afternoon differ reality to fertilization ofdaytime. Between fertilization dose and time there are interaction to high improvement of dry weight and crop of]soy seed.

Abstract

This study explores the influence of optimizing digital resources and learning discipline on student achievement in blended learning. Using a quantitative method with a survey design, data were collected from 150 high school students randomly selected from a population of 500 students. The instrument, a questionnaire, was tested for validity (score > 0.70) and reliability (Cronbach’s Alpha > 0.80), ensuring a reliable measurement tool. Classical assumption tests were conducted, including normality, homogeneity, and multicollinearity tests, which indicated that the data met all prerequisites for multiple linear regression analysis. The analysis results show that optimizing digital resources significantly affects student achievement (Beta = 0.45, p < 0.001), as does learning discipline (Beta = 0.38, p < 0.001). The coefficient of determination (R² = 0.56) indicates that 56% of the variation in student achievement can be explained by these two variables. The limitations of this study include the sample size and specific context. Recommendations for future research are to expand the population scope and explore other factors, such as motivation and social support, for a more comprehensive understanding of the effectiveness of blended learning.
