PERBANDINGAN KEANEKARAGAMAN DAN PREDOMINANSI FAUNA TANAH DALAM PROSES PENGOMPOSAN SAMPAH ORGANIK

Abstract

Abstract
Actually, the problem of garbage can be solved by a good management, for example
decomposition. Decomposition occure as a result of soil fauna activities. This research was
aimed to analyse comparation the diversity and predominance of soil fauna in the
decomposition all kinds of organic garbage. It was designed as an experimental study with
garbage variation were : the agriculture garbage, the cattle faeces, the city garbage, mixture
of agriculture garbage and faeces of cattle, mixture of agriculture and city garbages, mixture
of cattle faeces and city garbage, and mixture of three kinds of garbage. The soil faunas
were collected with Pitfall-traps and soil cores. The diversity indeks (H’) of soil fauna was
analized by Shannon-Wienner indeks, while the predominance of soil fauna was counted
based on the base of its relative abundance (RA). The highest diversity indeks of soil fauna
was found at PTK, H’=3,01, while the lowest was found at P, H’=1,60. The kinds of
predominant soil fauna were Hypogastrura armata (RA=71%), Carohodes marginatus
(RA=54%), Cllohmannia gigatea (RA=30,3%), Phidole sithyesi (RA=19,1%), Suctobelba
obtusa (RA=13,9%), Polyrhachis hauxwelli (RA=9,27), Lepidocyrtus pictus (RA=8,85%),
Tetranychus canadensis (RA=7,07%), Narceus americanus (RA=7%), Entomobrya cingula
(RA=6,82%), Lasius fuliginosus (RA=5,14%), and Isotomurus tricolor (RA=5,03%).
