Administratively, the location of the survey is included in the Village area Hukurila,
South Leitimur District, the city of Ambon. Geographically located between 127 ° 28 '51.2"
East Longitude - 128 ° 46' 11.2" east longitude and 2 ° 49 '51.5 "south latitude - 3 ° 33' 39.8"
South latitude. The research area is divided into five geomorphic units are: the plains, karst
topography, hills, mountains, and volcanic systems.
The research area is composed by several rock units from old to young is: the
ultramafic rock units, granite, sandstone Kanikeh, volcanic breccia rock, units of coral
limestone, and alluvial deposits. Geological structures that develop in the region is robust and
fault. Fault structures that develop are : Right Slip Normal Fault.
To determine levels of Ni in this area, the authors took samples from drill results by
using a hand auger at limonit zone and tested using by AAS method. Ni content of the test
results with AAS method, obtained the following results: LP 38A 0.50% Ni, LP 38B levels
of 0.32% Ni, LP 38C content of 0.31% Ni, LP 37 Ni 0.081%, LP 36 Ni content of 0.70%, LP
35 levels of Ni 0.34%, LP 34 levels of Ni 0.63%, LP 31 levels of Ni 0.18%, LP 22 levels of
Ni 0.23%, LP 20 levels of Ni 0.32 %. And it can be concluded that the levels of Ni in the
region telitian greatly influenced by the thickness of the zone limonitnya. The thicker
limonitnya zone, the greater its Ni content.

Secara administratif lokasi survei termasuk dalam wilayah Desa Hukurila,
Kecamatan Leitimur Selatan, Kota Ambon. Secara geografis terletak diantara 127° 28’
51,2” Bujur Timur - 128° 46’ 11,2” Bujur Timur dan 2° 49’ 51,5” Lintang Selatan - 3°
33’ 39,8” Lintang Selatan. Daerah telitian dibagi dalam lima satuan geomorfik ialah :
dataran, karst topografi, perbukitan, pegunungan, dan sistem vulkanik.
Daerah telitian tersusun oleh beberapa satuan batuan dari tua ke muda adalah:
yaitu satuan batuan ultrabasa, satuan batuan granit, satuan batupasir Kanikeh, satuan
batuan breksi vulkanik, satuan batugamping terumbu, dan endapan alluvial. Struktur
geologi yang berkembang pada daerah telitian adalah kekar dan sesar turun. Struktur
sesar yang berkembang adalah: Right Normal Slip Fault.
Untuk mengetahui kadar Ni dari daerah telitian, penulis mengambil conto dari
hasil bor dengan menggunakan hand auger pada zona limonitnya dan diuji dengan
menggunakan metode AAS. Dari hasil pengujian kadar Ni dengan metode AAS,
didapatkan hasil sebagai berikut : LP 38A kadar Ni 0,50%, LP 38B kadar Ni 0,32%, LP
38C kadar Ni 0,31%, LP 37 kadar Ni 0,081%, LP 36 kadar Ni 0,70%, LP 35 kadar Ni
0,34%, LP 34 kadar Ni 0,63%, LP 31 kadar Ni 0,18%, LP 22 kadar Ni 0,23%, LP 20
kadar Ni 0,32%. Dan dapat disimpulkan bahwa kadar Ni pada daerah telitian sangat
dipengaruhi oleh ketebalan dari zona limonitnya. Semakin tebal zona limonitnya,
semakin besar juga kadar Ni-nya
