Abstract

Abstract-The development of the agricultural sector has resulted in the increase of the environmental pollution by chemicals, such as; persistent organochlorine contaminants, can undergo bioaccumulation in nature. Ramadhani and Oginawati (2009) stated that organochlorine compounds classified as Persistent Organic Pollutants (POPs) are chemical compounds that are persistent in the environment, can undergo bioaccumulation in the food chain, and has the risk of being the cause of many negative impacts on human health and the environment. In the agricultural area, there are microorganisms in the soil that act as decomposers of organic materials or use organic materials as food. This research was conducted at the Microbiology Laboratory of the Research Center for Biology LIPI Cibinong February 2012 to August 2012. Isolation and characterization of microbes degrading Persistent Organic Pollutants (POPs) performed at the Laboratory of Microbiology Research Center for Biology LIPI Cibinong by using three stages, (1) Isolation and identification of POPs degrading microbes, (2) test the growth characteristics of the isolates in the different types of POPs. The purpose of the study is to select the bacteria in the soil that could potentially degrade the insecticide residues that have the characteristics of POPs ( dieldrin , DDT , aldrin , heptaklor ) . The results of bacterial isolation study shows that there are five (5) types of bacteria which are able to degrade POPs ( dieldrin , DDT , aldrin , heptachlor ). Those bacteria are Achoromobacter sp, Catenococcus thiocycli, Heliothrix oregonensis, Bacillus cereus ,Bacillus subtilis. Keywords: soil, isolation, POPs, degrading bacteria

Abstract

Spent brewer’s yeasts are a by product of the beer production, containing useful bioactive substances, such as proteins, amino acids, nucleotides, carbohydrates, minerals, and vitamins. Up till now,  intact  spent brewer’s yeast has been used as a supplement to animal feed. High protein content in spent brewer’s yeast (45-60% in dry weight) makes it good to be produced into yeast extract (YE) as a protein source. YE consists primarily of amino acids, peptides, nucleotides, and other soluble components, that are needed in microbiological media. This study aims to determine the differences between four physical or mechanical treatments (freezing-thawing, homogenization, glass beads, and combination of freezing-thawing and glass beads) in YE production of the cell distruption and protein content, and the quality of YE produced for microbiological media. Measurements of cell count and dissolved protein content were performed to determine the best physical method, while physical, chemical, and biological parameter measurements were performed to determine the quality of YE. The results showed that the best treatment for cell distruption was combination of freezing-thawing and glass beads with percentage of distrupted cell and soluble protein content of 99.5% and 2.779 mg / ml, respectively. YE from spent brewer's yeast contains soluble protein and α-amino nitrogen as much as 3.671 and 1.352 mg / ml, and total nitrogen and crude protein of 2.21 and 13.81 mg / ml, lower compare to commercial YE. Biological testing data YE from spent brewer's yeast has ability to increase cell density (OD) and number of colonies in E. coli, Staphylococcus epidermidis, and Saccharomyces cerevisiae D.01.Further research on the use of spent brewer’s yeast to produce YE using spent brewer’s yeast without steam and glass beads with diameter less than 0.5 mm is necessary to improve the yield and quality of the YE.

Abstract

Since three years ago Plant Physiology lecture has been using a model of learning Reading, Questioning, and Answering System (RQA), but the results are still not satisfactory. Three open classes of Lesson Study (LS) has been implemented to improve the lecture on April 4, 7, and 14,  2014 by the LS Team consisting of three lecturers and four assistant lecturers. The input for improving the teaching and learning process of lecture conducted as a result of reflection before and after three open classes covers additional tasks preparing a concept map or mind map tasks besides RQA, the improved form of  power point presentation,  improved mastery of material by the  presenters, query answering written questions in the Chapter Review  that the material covered is more substantial. Presenters should also display images related to the  material being discussed, request that the student submit the RQA power point at the beginning of lecture, and gave a rebuttal that is not a technical issue but a substantial concerns, as well as write and collect lecture notes at the end of the course. The results showed an improvement in the learning  processes and increased student engagement in learning. Plant Physiology improvement of learning outcomes is still not satisfactory . Keywords: improvement, quality of lectures, Plant Physiology , Lesson Study , FMIPA UM
