ZEOLITE: STRUCTURE AND POTENTIAL IN AGRICULTURE
Get PDFZeolite is a hydrated aluminosilicate mineral with a three-dimensional structure. The unique zeolite crystal structure makes zeolites have cation boundary properties, adsorption, molecular sieving, catalysts, capture, and release of air molecules. Many studies in various fields including agriculture have been done by utilizing the properties of the zeolite. Indonesia has an abundant source of zeolite reserves and extensive agricultural areas, making it possible to apply zeolite research results to support sustainable agricultural activities. In this article will discuss the potential utilization of zeolite in agriculture based on the studies that have been done

Get PDFTeacher - center method more widely used in the learning process but knowledge gained students less than the maximum. Therefore, The researcher intended to carry out the process of learning that guides the students discover the concept through their own behavior so that the results are more meaningful and is expected to increase the achievement. This research aimed to describe the effect of the application of Guided Discovery model to the students’ achievement, both affective (scientific attitude), psychomotor, and cognitive, as well as to determine the linkages between these aspects. This research was designed using "True Experimental Design" conducted at SMP Negeri 1 Pucuk. The data obtained was the pre-test, post-test, and scores of psychomotor and affective abilities. Furthermore, the data were analyzed with statistical consisting of normality test, homogeneity, and hypothesis testing, and regression and correlation analysis. Post-test results were analyzed by t-test. T-test results obtained by the two parties –ttable t ttable shows the differences between control and experimental class. The t-test results obtained by the right parties tcalculation≥ ttable (α= 0.05) showed that results for students in the experimental class is better than the control class. It can be concluded that the application of Guided Discovery model can improve the students’ achievement in the material of motion in SMP Negeri 1 Pucuk. The increase in value of the students’ psychomotor and affective effect on the increase in value of the students’ cognitive

THE RHIZOSPHERE PGPR GRAMINEAE APPLICATION ON THE GROWTH RED GINGER (Zingiber officinale Var. Rubrum)
No full textPGPR (Plant Growth Promoting Rhizobacteria) is a group of bacteria that colonize in the area of the rhizosphere. These groups of bacteria favor plant growth because they are able to mobilize and provide nutrients and phytohormones. The ability of the bacterial group can be utilized as a growth regulator in the red ginger nursery (Z. officinale Var Rubrum). This study aims to determine the optimal dosage of PGPR for the growth of red ginger seed (Z. officinale Var Rubrum). In this study, red ginger rhizome (Z. officinale Var Rubrum) was soaked with various concentrations of PGPR ie 0%, 25%, 50%, 75% and 100%. The results of this study indicate that soaking rhizomes using PGPR solution significantly influence the growth of red ginger seeds in the form of high seedlings, the number of shoots grow, the number of leaves and the mass of seedlings. A 25% dose has a better ability to boost the growth of seeds when compared to other doses.Keywords: Zingiber officinale Var. Rubrum, PGR, Phytohormone

INFLUENCING OF PROJECT-BASED LEARNING MODEL TOWARD SCIENCE PROCESS SKILLS ON ENVIRONMENT MANAGEMENT MATERIAL
No full textThis study aims to determine the effect of the application of Project Based Learning Model to Skill of Science Process on Environmental Management Material. This research design uses posttest-only control design with Quasi-Experimental method (quasi-experiment). The sample of this research is 35 students. Based on the results of the analysis of students' science process skills show that the implementation of learning using the model of Project Based Learning is better than the conventional learning model. This can be seen from the calculation of the test-t skills of the science process shows for sig tcount 0.000 0,05, then Ha accepted and H0 rejected. The result of analysis of the average score of mastery of experimental science process skill class achieves 2.87 with good criteria while the students 'science process skill in control class 1.73 is sufficient to mean that the students' experimental class science process skill is higher than the control class science process skill. Thus, it can be concluded that the model of Project Based Learning affects the Skills of Science Process on Environmental Management Material.Keywords: project based learning model; skills of science process
