Salvinia molesta merupakan limbah Waduk Batu Tegi yang berpotensi sebagai
sumber pakan ternak nonkonvensional. Informasi tentang kandungan mineral dan
pemanfaatannya belum banyak diketahui.
Penelitian ini bertujuan untuk mengetahui kandungan mineral natrium (Na),
kalium (K), klorida (Cl), dan sulfur (S) pada akar tua, akar muda, daun tua, daun
muda, dan seluruh tanaman kiambang (Salvinia molesta) serta mengetahui
kandungan mineral natrium (Na), kalium (K), klorida (Cl), dan sulfur (S) tertinggi
sampai terendah pada masing-masing bagian tanaman Salvinia molesta.
Penelitian ini dilaksanakan pada bulan Maret{--}Mei 2012. Sampel kiambang
(Salvinia molesta) diambil dari Waduk Batu Tegi Tanggamus. Rancangan yang
digunakan adalah Rancangan Acak Lengkap dengan pembagian tanaman sebagai
perlakuan dan periode analisis sebagai ulangan, dilanjutkan dengan Uji Beda
Nyata Terkecil. Peubah yang diamati adalah kandungan mineral natrium (Na),
kalium (K), klorida (Cl), dan sulfur (S).
Hasil penelitian menunjukkan bahwa terdapat perbedaan sangat nyata (P{\ensuremath{<}}0,01)
pada kandungan mineral Na dan K yang terdapat di semua bagian tanaman
Salvinia molesta sedangkan kandungan mineral Cl pada bagian daun muda, akar
tua, dan tanaman utuh terdapat perbedaan sangat nyata (P{\ensuremath{<}}0,01 ). Kandungan
mineral S pada bagian akar tua, daun tua, dan tanaman utuh berbeda sangat nyata
(P{\ensuremath{<}}0,01). Kandungan mineral Na, K, CL, S berturut-turut pada bagian daun muda
adalah 1,20\%, 2,11\%, 2,14\%, 0,08\%; daun tua 1,14\%, 0,88\%, 1,42\%, 0,52\%; akar
muda 0,82\%, 1,54\%, 0,20\%, 0,06; akar tua 0,64\%, 1,01\%, 0,23\%, 1,52\%; dan
tanaman utuh 0,93\%, 1,25\%, 1,21\%, 0,57\%.

Abstract

Salvinia molesta is a weed reservoir Batu Tegi potential as a source of nonconventional fodder. Information on the mineral content and its use has not been
known.
This research was aimed to identification the mineral content of sodium (Na),
potassium (K), chloride (Cl), and sulfur (S) to the old roots, young roots, old
leaves, young leaves, and whole plant Salvinia molesta with to know mineral
content of sodium (Na), potassium (K), chloride (Cl), and sulfur (S) highest to
lowest in each part of the weed Salvinia molesta.
This research was conducted in March-May 2012. Salvina molesta is taken from
the reservoir Batu Tegi Tanggamus. Data were analyzed by Analysis of Variance
completely randomized designed and the differences among treatments were
tested by Least Significant Difference. The variable measured were the minerals
sodium (Na), potassium (K), chloride (Cl), and sulfur (S).
The results showed that in the mineral content of Na and K was present in all parts
of the plant Salvinia molesta there were highly significant differences (P {\ensuremath{<}}0.01)
while mineral Cl content on the young leaves, old roots and whole plants there
were highly significant differences (P {\ensuremath{<}}0.01). Mineral S content on the young
leaves, old roots, and whole plants were highly significant differences (P {\ensuremath{<}}0.01).
Mineral content of Na, K, CL, S respectively in the young leaves was 1.20\%,
2.11\%, 2.14\%, 0.08\%, 1.14\% old leaves, 0.88\%, 1 , 42\%, 0.52\%; young roots
0.82\%, 1.54\%, 0.20\%, 0.06; older roots 0.64\%, 1.01\%, 0.23\%, 1.52 \%, and the
whole plant 0.93\%, 1.25\%, 1.21\%, 0.57\%.
