PERTANAMAN NANAS (Ananas comosus L. Merr) DI TANAH ULTISOL
LAMPUNG TENGAH SETELAH PEMBERIAN PUPUK CAMPURAN
DENGAN PERBEDAAN TEKNIK DAN DOSIS APLIKASI

%X Populasi dan keanekaragaman mesofauna tanah merupakan indikator kesuburan
tanah yang dipengaruhi oleh penggunaan pupuk dalam tanah. Pupuk campuran
(mix fertilizer) pada penelitian ini merupakan produksi PT GGP (Great Giant
Pineapple) dengan campuran bahan organik dan anorganik yang mengandung
unsur hara makro, mikro, serta amelioran yang diharapkan mampu meningkatkan
populasi dan keanekaragaman mesofauna tanah. Tujuan dari penelitian ini adalah
untuk mempelajari pengaruh teknik aplikasi dan dosis aplikasi pupuk campuran
terhadap populasi dan keanekaragaman mesofauna tanah pada pertanaman nanas
(Ananas comosus L. Merr.), serta mempelajari korelasi populasi dan
keanekaragaman mesofauna tanah. dengan C-organik, pH tanah, kadar air, dan
suhu tanah. Penelitian dilakukan di PT. GGP dan analisis tanah dilakukan di
Laboratorium Ilmu Tanah Universitas Lampung. Penelitian ini menggunakan 
rancangan petak terbagi yang terdiri dari 9 perlakuan dan 4 ulangan. Data 
dianalisis dengan analisis varian dan uji tukey dilanjutkan dengan uji BNT pada
taraf 5%. Hasil penelitian menunjukkan teknik aplikasi tidak berpegaruh terhadap
populasi dan keanekaragaman mesofauna tanah. Dosis aplikasi pupuk campuran
4,5 ton ha
-1
 menunjukkan populasi dan keanekaragaman mesofauna tertinggi
dibandingkan dosis aplikasi lainnya. Uji korelasi menunjukkan bahwa tidak ada
korelasi antara populasi dan keanekaragaman mesofauna tanah dengan C-organik,
pH, kadar air, dan suhu tanah.

 Population and diversity of soil mesofauna is an indicator of soil fertility which is
influenced by the use of fertilizers in the soil. The mixed fertilizer that used in this
research was produced by PT GGP (Great Giant Pineapple) with a mixture of
organic and inorganic materials containing macro and micro nutrients, also soil
ameliorants which are expected to increase the population and diversity of soil
mesofauna. The purpose of this research was to study the effect of different
application techniques and application dosages of mixed fertilizer application on
the population and diversity of soil mesofauna in pineapple (Ananas comosus L.
Merr.) plantations, as well as study the correlation of soil mesofauna population
and diversity with organic-C, soil pH, water content, and soil temperature. This
research was conducted at PT. GGP and soil analysis were carried out at the
Laboratory of Soil Science, University of Lampung. This research used a split plot
design consisting of 9 treatments and 4 replications. Data were analyzed by
analysis of variance and tukey test followed by LSD test at 5% confidence level.
The results showed that the application technique had no effect on the population
and diversity of soil mesofauna. The mixed fertilizer application dose of 4.5 tons
ha
-1
 showed the highest mesofauna population and diversity compared to other
application doses. Correlation test showed that there was no correlation between 
population and soil mesofauna diversity with organic-C, pH, moisture content, 
and soil temperature.
