Today's global world changes encourage schools to start making organizational changes. School leaders are expected to be able to develop competitive strategies and create organizational changes in schools. This study aims to determine the effect of transformational leadership on organizational change in elementary schools. This study uses a quantitative approach using simple linear regression test data analysis techniques. The independent variable in this study is the principal's transformational leadership while the dependent variable is organizational change. The sample was 396 respondents with simple random sampling method. The results of the study indicate that transformational leadership has an effect on organizational change in elementary schools. Organizational changes in elementary schools by 60% are influenced by the principal transformational leadership.

Kalimantan acid sulphate land has the potential to be developed into productive land, with good land optimization. Utilization of rhizosphere microorganism diversity, especially mold can potentially provide a solution in optimizing agricultural land, namely the ability to produce extracellular enzymes. This study aims to determine the potential of mold originating from acid sulphate fields in producing extracellular enzymes (pectinase, chitinase, glucanase, cellulase, and phosphatase). The study was conducted in June-July 2019 at the Microbiology Laboratory, Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development. Screening  of extracellular enzyme-producing fungi was carried out on selection media. The results obtained by some isolates have the ability to produce extracellular enzymes. Indications of the ability of mold to produce extracellular enzymes are the presence of clear zones in the selection medium. In pectinase, chitinase and glucanase testing all isolates showed negative results. Potential isolates in producing extracellular enzymes include Penicillium sp. Paddy 4.1 (cellulolytic index 2.43),  Clonostachys sp. KRMT 17.9 and Penicillium singorense KLK 13.7 (proteolytic indices 3.97 and 3,00, respectively). The difference in index values ??indicates the variation in the level of enzyme activity.
