Abstract :
In terms of bird pests, currently agriculture, especially rice fields, still uses
existing properties such as scarecrows, nets and others. The influence of this pest
greatly affects the productivity of plants and agriculture. Based on observations in
the journal the effect of bondol bird attacks on damage to rice plants in Bogor,
three species of bondol birds from the Ploceidae tribe were found, namely the
Peking bondol (Lonchura punctulate), Javanese Bondol (Lonchura
leucogastroides) and bondol haji (Lonchura maja). As a result of the habits and
preferences of birds to eat grain, this group of birds from this tribe becomes pests
that are very detrimental to farmers. Flapping Wing AF-1823 has wingspan 1 m
long and has a length fuselage 0.29m with maximum take off weight of 0.321 kg
and a tail length of 0.14 m. In the manufacturing process Flapping Wing AF-1823,
method laser cutting used to cut with precision parts fuselage, then method 3d
printing used in printing tale join, side base, and gears. Then method homemade
used for process assembly on all parts Flapping Wing AF-1823. As for the point
centre of gravity on Flapping Wing AF-1823 obtained location central of gravity
dotted 17,8 cm from the datum.
