Abstract

MOL contains superior microorganisms as decomposers activators of organic materials that can be used as plants fertilizer. The microorganisms that was contained in MOL was commercial biological agents. One way to get commercial biological agents was to look for potential bacteria that have a function as biofertilizer. The objective of this study was to screen for indigenous bacteria from MOL Bintaro fruit (Cerbera manghas L) that plays a role in the manufacture of biological fertilizers. The stages of this study were MOL making and sampling, sampling and bacterial screening by doing isolation and purification, continued by phosphate solvent bacteria test and IAA screening producing bacteria, then bacteria identification morphologically. The result of isolation and purification found that there were 35 kinds of bacteria from two samples of MOL Sample 1 was treated as 3 kg of Bintaro fruit and it was found that there were 18 bacteria. Furthermore, sample 2 was treated as 1.5 kg of Bintaro fruit and got 17 kinds of bacteria. The result of bacteria solvent screening found 7 isolates. The isolated bacteria that had the greatest solubility of phosphate were MBSD 6 with P isolated solvent index was 0.7 cm. The screening results of IAA-producing bacteria showed that MBSD 7 produced the highest IAA was 37.36 ppm and MBSP18 produced the lowest isolates was 6.27 ppm.

Abstract

This study aims to utilize household waste and used MOL (Micro-Organism-Local). MOL is used to assist the process of decomposition in composting. This study aims to isolate the bacterial origin of MOL with media of different organic materials and the application of the isolated bacteria as a biological fertilizer. Stages of research involved isolating bacteria from MOL vegetables, then do purification. The next stage is to identify the bacteria colony morphology that includes forms, cells, and Gram. This research is expected to contribute to the field, namely: the development of science, research methodology. First, for science to improve information research methods, research for further development activities for people who have an interest in the processing of biological fertilizers and organic fertilizers. Second, the methodology how to obtain microbes for use in applied research. The results were obtained bacterial isolates were collected from three kinds of treatment samples MOL namely MOL to-I (waste vegetable, sugar, rice water), II (vegetable waste, brown sugar, rice water), and III (waste vegetable, sugar sand, coconut water). The result of the isolation and purification of bacteria obtained amounted to 79 types of bacterial isolates comprising 23 species of bacteria from the sample MOL to-1, 30 species of bacteria from the sample to the MOL-II, and 24 types of bacteria from the sample to-III. Overall the data obtained from the sample to the MOL-I, II, and III of the highest number of bacterial cells present in the sample to the MOL-II with a number of types of bacteria most. This type of bacteria that is known at the time T0, T1.

Abstract

Swamps are part of relatively flat land along the coast, streams or lakes and there is vegetation in the form of water plants, leading to the land up to ± 100 km which is generally affected by tides from the surrounding rivers. The method used in this study is a qualitative descriptive method, namely a method of analysis that seeks to explain the conditions of the object of study according to certain criteria so that it can provide a real picture of what is happening in the research place. Public Perception of Swamp Function in the Musi Rawas Area. People living in O. mangunharjo Village use swamps to help farmers in the use of conversion of agricultural land. However, to find out people's perceptions of the function of swamps, there are ten questions to analyze the community's perceptions of the function of swamps in the Musi Rawas area. From the research activities, it is known that from the community's perception of the function of swampland in O. Mangunharjo village, Musi Rawas Regency, there are many activities or activities that occur around swamps carried out by farmers such as; looking for grass for livestock, then hoeing or plowing the fields and farmers who plant vegetables considering that swamps are very important to the balance of the environment, especially in the economy of the people around O. Mangunharjo village in Musi Rawas Regency, there are 2 respondents who do not know the impact of the damage the swamp ecosystem affects the surrounding environment and 3 respondents know its impact. Based on PKL activities, it can be concluded that the community knows the function of swamps in the surrounding settlements, namely that the presence of swamps can balance the ecological functions of the environment.
