N2  - Dung beetle merupakan anggota kelompok Coleoptera dari suku Scarabaeidae
yang lebih dikenal sebagai scarab. Perilaku dung beetle yang membawa kotoran
ke dalam liang sarangnya di dalam tanah. Perilaku itu secara alami akan
menambah unsur-unsur hara tanah dan secara tidak langsung.menggemburankan
tanah dengan liang-liang sarang yang dibuatnya. Penelitian ini bertujuan untuk
mengetahui perilaku dung beetle terhadap kepadatan tanah dan untuk mengetahui
sifat fisik tanah pada habitat dung beetle di Arboretum I dan Arboretum III Hutan
Pendidikan Terpadu Unila di Blok Pemanfaatan Tahura WAR. Penelitian ini telah
dilakukan pada bulan November-Desember 2018. Metode yang digunakan adalah
analisis tanah. Analisis tanah dilakukan di Laboratorium Mekanika Tanah Fakultas
Tehnik, Universitas Lampung. Data yang terkumpul dianalisis dengan rumus kadar air,
berat jenis, berat volume, analisa saringan serta uji pemadatan tanah standar. Hasil
penelitian menunjukkan bahwa semakin besar ukuran dung beetle memengaruhi
kemampuan menggali tanah akan semakin dalam. Kadar air rata-rata yang ada di
lapangan pada Arboretum I sebesar 43,55%. Berat jenis rata-rata tanah sebesar 2,64 gr.
Berat volume tanah kering rata-rata (?
d rata-rata) sampel sebesar 0,86 gr/cm

. Persentase
lolos saringan No.40 dengan diameter saringan 0,475 mm adalah sebesar 77,50%.
Pemadatan tanah standar pada arboretum I didapatkan nilai kadar air optimum sebesar
24%. Kadar air rata-rata pada Arboretum III sebesar 49,56%. Berat jenis rata-rata tanah
sebesar 2,44 gr. Berat volume tanah kering rata-rata (?
d rata-rata
) sampel sebesar 0,99
gr/cm

. Persentase lolos saringan No.40 dengan diameter saringan 0,475 mm adalah
sebesar 71,08%. Pemadatan tanah standar pada arboretum III didapatkan nilai kadar air
optimum sebesar 28%.

Dung beetle is clasified as a group of Coleoptera and the family of Scarabaidae
wich known as scarab. The behavior of dung beetle was carrying the dung to their
nest on the soil. This behavior naturally added the soil nutrient and indirectly
made a loose soil by the nest burrows. This research aims to determined the
behavior of dung beetle toward the soil density and to find out the soil physical in
the dung beetle habitat at Arboretum I and Arboretum III Unila Integrated
Education Forest in the Tahura WAR Utilization Block. This research was
conducted between November-December 2018. The method that used was soil
analysis. The soil was analyzed at the Soil Mechanics Laboratory, Faculty of
Engineering, University of Lampung. The collected data were analyzed used
formula of water content, specific gravity, volume weight, filter analysis and
compaction test of standard soil. The results showed that greater size of the dung
beetle, effected the ability of soil dig will be deeper. The average of water content
in the field in Arboretum I was 43.55%. The average of soil density of 2.64 gr.
