Abstract

Planting area of oil palm plantations in Lampung Province is in the rank 13 th of Indonesia. Empty Oil Palm Bunches (EOPB) is an organic waste from fresh fruit bunches. The amount of EOPB is exceeded but it is not used optimally yet. This research aimed to study the effectiveness of the local microorganisms solution (MOL) of EOPB in aerobic condition, especially for bacterial population and and bacterial characteristics in EOPB MOL solutions. The observations were done by counting the number of bacterial population and bacterial characteristics were differentiated based on shape and color. In addition, other characteristics were also done in the form of grams’ test, oxidative fermentative’s test (O/F) test, soft rot’s test, hipovirulen’s test, and hypersensitive. The results show that there were 84 isolates of bacteria found were isolated and tested its characteristics. In the EOPB MOL solutions under aerobic condition, the numbers of bacterial population obtained at each sampling time were different. The highest number of isolates was 197.96 x 10 12 in the 18 days after the EOPB MOL solutions was made (HSP) and the lowest was 0.02 x 1012 at 15 HSP. Form of colonies obtained were rounded and irregular with murky white, white, red, yellow, orange, yellowish white, dark yellow, and clear. Most of the bacteria were 71.43% Gram-positive, 90.48% fermentative, 75% negative in softrot, 78.5% virulent,and 94.05% negative in hypersensitive test.
