Comparison between wavelet transform and moving average as filter method of MODIS imagery to recognize paddy cropping pattern in West Java

Information on the area and spatial distribution of paddy field are needed to support sustainable agricultural and food security program. Mapping or distribution of cropping pattern paddy field is important to obtain sustainability paddy field area. It can be done by direct observation and remote sensing method. This paper discusses remote sensing for paddy field monitoring based on MODIS time series data. In time series MODIS data, difficult to direct classified of data, because of temporal noise. Therefore wavelet transform and moving average are needed as filter methods. The Objective of this study is to recognize paddy cropping pattern with wavelet transform and moving average in West Java using MODIS imagery (MOD13Q1) from 2001 to 2015 then compared between both of methods. The result showed the spatial distribution almost have the same cropping pattern. The accuracy of wavelet transform (75.5%) is higher than moving average (70.5%). Both methods showed that the majority of the cropping pattern in West Java have pattern paddy-fallow-paddy-fallow with various time planting. The difference of the planting schedule was occurs caused by the availability of irrigation water.

ASPEK LINGKUNGAN DAN PRODUKTIVITAS AYAM BROILER PADA SISTEM TRANSPORTASI TERTUTUP DAN KONVENSIONAL

Population of broiler chicken increase continuously every year. This situation indicated broiler farm in Indonesia has been transformed as a poultry industry. Broiler farm concentrated in one place far from human to anticipate the potency of air pollution. Transportations are used to mobilize broiler from farm to slaughter house or market. The transportation should con- sider the condition of broiler and environment to minimize the air pollution and negative effect in broiler performance. This re- search was aimed to evaluate effect of covered and conventional transportation system on environmental aspect and broiler per- formance. Sixty broilers was used in this research and divided into two treatments. Data was analyzed by t-Test with α 0.05. The result indicated that covered system better to reduce the potency of ammonia pollution than conventional system. Weight loss of broiler transported with covered system significantly lower (P<0.05) than conventional system. There were no mortality both in conventional and covered system. Distribution of temperature in covered system was significantly lower (P<0.05) than conven- tional system. Covered system, poultry transportation system based on animal welfare aspect showed lower in vocalization than conventional system.
