Abstract

Forest areas are where the most advanced water and air cycles occur and cannot be replaced by any man-made products. For this reason, Indonesians' lives and forest lands are inextricably linked as economic resources. Deforestation also occurs at a considerable rate in East Kutai Regency. Changes in the area of forest land, which is continuously decreasing, followed by a growth in land area for other uses, including mining and plantations, serve as examples of this circumstance. To determine whether the conversion of this area is genuinely balanced between measures to protect the environment and the health of the soil and its economic value, more research must be done. One way to find out is to examine soil respiration in several locations. The purpose of the research was to compare soil respiration levels in three types of land cover in East Kutai Regency. The data collection method involves taking 0 – 30 cm depth of soil sample at three points in three locations, namely Rubber plantation, Teak plantation and Botanical Gardens. The total soil microorganism count is determined by soil organic carbon. The overall number of soil microorganisms increases with soil organic matter. Next, the soil samples are tested in the laboratory for colony total number. The study's findings indicated that the teak plantation had the lowest soil respiration, at21.37±0.9, and the Botanical Garden location had the highest, at29.87±1.91. The high total number of soil microorganisms makes respiration high because it produces high CO2, which is caused by the high activity of the microorganisms in the soil.

Abstract

This research is quantitative research using descriptive methods which aims to determine the description of the leadership of school principals, the performance of kindergarten teachers and the influence of the leadership of kindergarten principals on the performance of kindergarten teachers in Amali District, Bone Regency. The independent variable in this research is leadership, while the dependent variable in this research is teacher performance. The population in this study was the entire kindergarten teaching staff in Amali subdistrict, Bone district, while the sample in this study was taken as a whole from the total population using a sampling technique, namely nonprobability sampling. The data analysis technique used is simple linear regression analysis. Based on the results of the descriptive analysis, it was found that the principal's leadership was classified as good with a percentage of 48.3% and teacher performance with a percentage of 43.3% was classified as very low. There is a positive influence between the leadership of kindergarten principals on the performance of kindergarten teachers in Amali District, Bone Regency. With a coefficient of determination value of 46.8% which is in the very low category, it can be concluded that teacher performance can run well even though the principal's leadership has not been optimal in carrying out its duties and functions, so the principal's leadership needs to be improved so that teacher performance is better.
