Abstract

Utilization of ultisols in Southeast Sulawesi may be approached by inoculating viable arbuscular mycorrhizal fungi (AMF) exposing plant growth-promoting activities to the growth of native economical plants. This study investigated a combination of AMF and liquid organic fertilizers from coconut husks to improve the growth of soybean plants grown on ultisols as one of the potential marginal soils in the region. The coconut husk served as an abundant, cheap, yet potential source for the preparation of liquid organic fertilizers. This study used two factorial design with four treatment levels. The first factor was designed for different AMF species (10 g/pots): control (M0), Acaulospora delicata (M1), Septoglomus constrictum (M2), and Claroideoglomus etunicatum (M3) while the second factor was designed for different concentration of liquid organic fertilizer (mL/pots): control (P0), 150 mL/pots (P1), 200 mL/pots (P2), and 250 mL/pots (P3). Based on ANOVA results, the independent application of AMF species and liquid organic fertilizers gave significant results in regards to the experimental variables such as plant height, number of leaves, leaf area, and stem diameter. The best combination of treatment was observed in the treatment using Septoglomus constrictum with the concentration of liquid organic fertilizer of 250 mL (M2P3) to yield the highest growth performance of soybean plants on ultisols.

Abstract

The purpose of this study was to determine and analyze the influence of leadership and management of school principals together on the performance of junior high school teachers in Air Kumbang District. The research method used in this research is descriptive quantitative research method. The instrument used in the study was a questionnaire. Testing requirements analysis hypothesis testing. There are 3 conditions that must be met before conducting regression analysis, namely 1) normality test; 2) homogeneity test; and 3) linearity test. Based on the results of the above research, it can be concluded that there is a significant influence between the leadership of the principal on the performance of teachers in SMP in Air Kumbang District, which means that the better the leadership of the principal, the better the performance of SMP teachers in Air Kumbang District . Thus it can be concluded that the second hypothesis is accepted. From the results of this study the authors suggest to other researchers, to examine the performance of teachers in Air Kumbang District, to include other variables such as motivation, compensation, level of education that can affect teacher performance.
