The optimation of farmers families' revenue the integration of Pasundan cattle and paddy farming in West Java

(2) yintegration = 15,721,319.75 - 72.541 land - 1.317 fertilizer + 4.667 seeds + 487765.94 farming labour + 6339170.199 cattle value - 935.559 feed + 162618.999 cattle labour. there were some conclusions: firs t,the integration of pasundan cattle and paddy farming produced the optimum family revenue/year,with ratio of 6.02 animal unit and 0.5 ha of paddy farming; second,the production factor of agricultural land,labour,seeds,feed and capital (cattle) were explained (r2=87.66%) toward the integration revenue; third,the variable which has the contribution to leverage the revenue was the capital of cattle (81.52%).
