law of conservation of matter

Effort exploiting of agriculture farm [is] intrinsically addressed to get pickings of agriculture commodity. Activity management of farm sumberdaya in this case basically represent adjustment effort [among/between] condition of existing farm with conditions to ko- agriculture moditas ( Sitorus, 1985). Condition of this farm become constraint limiting ability and according to farm sumberdaya to conditions of usage and exploiting of farm. morely operational, conception about condition of this farm can be formulated in conception of[is quality of farm able to evaluate morely kuanti¬tatif and more objective ( Soemarno, 1990; Janssen, 1991). [Relation/Link] [among/between] condition of farm with crop respon in the effort management of farm will determine farm productivity storey;level ( Wood and of Dent, 1983). Various technique have been developed to estimate farm productivity storey;level [pass/through] process evaluate farm. Result of evaluation is important in order to planning and pengelo¬laan of farm sumberdaya ( Sys, 1985; Soemarno, 1990).

One of [the] form management of famous farm [is] to use farm as system component of usahata¬ni. A[N system of usahatani commodity practically very complex ( natural sumberdaya subsistem, and sosial-ekonomi-budaya subsis¬tem), having the character of is dynamic, and senan¬tiasa have interaction [to] with other systems. Systematical approach qualify for the shake of efficacy of observation of commodity usahatani in its [his/its] framework ( Dent and of Young, 1971; Shanner, al et., 1982). Passing to with refer to systems analysis can be analyzed [by] system struk¬tur in the effort getting optimal structure, so that with system input simulation expected can be obtained [by] expected output. Furthermore implication [is] enabling of engineering of agroteknologi instruction for every system of usahatani commodity [in] a[n region of pengem¬bangan ( Soemarno, 1988).
