Paddy croppingtime has a very important role in the final production of agricultural cultivation. Currently, there are 3 croppingtime in Indonesia, in the rainy season (November to February), first of dry season (March to June), and second ofdry season, (July to October). However, the climate change dynamic such as drought (El Nino) and wetness (LaNina), shifting the cropping time and resulting a negative impact on the productivity of paddy rice. Therefore, ananalysis of the rice cropping time needs to be done on Kalimantan tidal swampland area. Cropping time in thetidal swampland area began after the amount of rain was sufficient to dissolve the levels of iron in water. In WestKalimantan, the cropping time realization generally occurs in Dasarian 28 (October), while East Kalimantan onDasarian 31 (November), and South Kalimantan and Central Kalimantan on Dasarian 7 (March).

Bacteria were isolated from foursoil samples from marginal land of Srowot Village, Karangrao Village, Tanggeran Village, and PagaralangVillage of Banyumas Regency. Bacterial populations and macromorphologic colonies were observed fordetermination of dominant bacterial colonies. The dominant bacteria were grown on NB media for 26 hours tosee the growth curve. Bacteria with the best growth curve then incubated on NB media containing buprofezin 0ppm, 5 ppm, 10 ppm, and 15 ppm to see further growth rate. The variables observed were the population of soilbacteria, the character of the macromorphology of the bacteria, the rate of bacterial growth in the media withoutpesticides, and the rate of bacterial growth in the media containing buprofezin. In this study, four dominantbacterial colonies, namely, SR2, KR1, TG4, and PA11 were isolated from 26 colonies grown on NA mediacontaining buprofezin 2 ppm. Observation of growth rate on NB media without pesticide showed colony of SR2has the best growth rate.
