The importance of the principal's strategies in realizing adiwiyata school (also called green school) drawn the author's interest in conducting a literature review. Environmental thoughtfulness is a mutual awareness and responsibility for every human being. Efforts are required for human to realize environmentally-thoughtful behavior. In the world of education, environmentally thoughtful behavior is applied at the adiwiyata school which is an environmental-based educational institution. As the school's highest leader, the principal is expected to have a plan in place to carry out a program. The research method used is literature review. The goal of this literature review is to obtain a theoretical foundation that can be used to support problem solving in relation to the principal's strategies in realizing adiwiyata schools. The result of the study on the principal's strategies indicate that the principal's strategies have an impact on the program's succession. The principal is in charge of carrying out management functions such as planning, organizing, implementing, and controlling the program.
Bacillus coagulans T1.2, an indigenous bacterium from shrimp ponds in East Lampung, has been found to reduce total ammonia nitrogen (TAN). The purpose of this study was to know the effectivity of immobilization of bacterial by sodium alginate from marine brown algae to reduce wastewater pollution from shrimp culture. The brown algae, Sargassum sp. and Padina sp., were collected from Pesisir Barat and Ketapang beach, Lampung. Alginate was extracted from both Sargassum and Padina by alkali method. The bacterial immobilization beads were made by mixed Bacillus coagulans suspension with alginate (1:3 v/v) and formed beads by 1,5 ml syringe without needle. In the in vitro study, the immobilized bacteria were submerged in artificial wastewater (2 beads ml-1) and incubated for 20 days. The control group includes the same bacteria without immobilization. The TAN was measured and the viability of bacteria was evaluated after the incubation period. The results showed that using alginate from Sargassum sp. and Padina sp. as a matrix of immobilization indigenous bacterial Bacillus coagulans effectively and significantly reduce the content of Total Ammonia Nitrogen (TAN) in wastewater. The viability of bacteria immobilized with the alginate of Sargassum sp. and Padina sp. better than the bacterial treatment without immobilization.
