Today, land use change has become one of the major issues in a developed region. Therefore, it is always importantto monitorland use changewithin a certain period of time and predictpatterns offuturelanduse change on a spatial basis. The mainobjectiveofthisresearchisto assessland use changein Maros regency up to a 20 year period. The analysis of land use change utilizes an integrationmethod of Cellular Automataand Markov Chain (Cellular Automata-Markov)in Remote Sensing(RS) and Geographic Information System (GIS). The procedures used include:(i)) a preliminarydataprocessing(geometric correction, radiometriccorrection, preparation ofthe composite image, object recognition) of Landsat imagesacquiredin 2004, 2009,and 2012;(ii) classification ofmultispectral imagery; (iii)probability analys is to generate Transitional Probability Matrix, Transitional Area Matrix, and Markov RGF; (iv)validation of rasterMarkovRGF2012imagelayerwith2012 land useusing a Kappa index; (v) usingthe same analysisin step(iii)butconsidering thedrivingfactorsof landuse changeandconstrains; (vi)Analysis using CellularAutomata-Markov togenerateland use changein the next 20years. The results showthat in year 2029, an increase inbuilt up area, but on the other hand, a declineinagricultural landuseespecially paddy fields, agricultural land,waterbodies, andother uses. In terms of land use decision making perspective, such information may be used to direct land use change to a more beneficial and sustainable situation.

The use of probiotic affects the aquatic animals’ immune response and growth performance. This study aimed to isolate bacteria from freshwater lobster’s intestines and observe in vitro the isolate’s ability in utilizing alginate from brown alga (Sargassum sp.) as a prebiotic. The bacteria was isolated from the freshwater lobster (Cerax quadricarínatus) intestine’s and the water of the lobster habitat. The lobster were collected from four stations i.e., Makassar, Bantimurung, Maros and Mandalle. The results of the study showed that after being soaked in a physiological solution with a pH of 2, there were 30 species of bacterial isolates discovered. The antagonistic test of inhibition zone against the pathogenic bacteria Aeromonas hydrophila showed the isolates of MDL7, MKS4 and MKS3 might inhibit the growth of A. hydrophila. While co-culture antagonistic test revealed that the isolates MDL1, MDL3, MDL6, BTL5, MRS4 and MRS5 could inhibit the growth of the pathogenic bacteria A. hydrophila. In vitro culture of alginate as prebiotic with the four best isolates as probiotic candidates, namely MDL7, MKS4, BTL5 and MRS5 demonstrated that the probiotic bacteria could grow and utilized prebiotic optimally, especially the MRS5 and BTL5 probiotic bacteria. Therefore, alginate as a prebiotic and MRS5 and BTL5 as probiotic bacteria have a great potential to be a symbiotic. © Asian Network for Scientific Information, 2014.
