Abstract
ABSTRAKPinctada maxima merupakan jenis kerang mutiara yang dibudidayakan di NTB.
Perubahan jenis kelamin atau fungsi gonadnya sangat ditentukan oleh faktor lingkungan
(makanan) dan kemampuan metabolisme untuk menghasillkan energi atau protein serta
hormon reproduksi (FSH atau LH) yang dihasilkan. Penelitian yang telah dilakukan pada
tahun 1997 terhadap kadar LH dari 10 ekor kerang mutiara saat spawning dan seminggu
setelah spawning yang menggunakan spektrofluorometri (TLC) dan analisa statitik
dengan uji t. Hasilnya menunjukkan bahwa kadar LH (Luteinizing Hormone) sangat tinggi
(61,533 ppm/cc) pada saat spawning, dan seminggu setelah spawning menurun menjadi
52,926 ppm/cc. Indikasi ini menunjukkan bahwa kadar LH pada kerang mutiara dalam
waktu 1 minggu mengalami penurunan yang sangat signifikan (8,607 ppm/cc) dengan
thitung= 5,10 pada taraf signifikansi 5% dan ttabel = 4,03. Penurunan ini kemungkinannya
akan mencapai titik neutral. Hal ini menunjukkan bahwa kadar LH sangat menentukan
pertumbuhan dan perkembangan gonad pada kerang mutiara.

ABSTRACT
Pinctada maxima are oyster pearl of cultures in NTB. The sex or functional gonad
change are the very heighten food factor in environment and the metabolism ability for
hormone reproduction (FSH and LH). The research is already in 1997 year, tendency for
to know LH grade spawning time and after spawning a weekââ¬â¢s to tail ten at oysterââ¬â¢s pearl
is same. The LH grades analysis use spektrofluorometri (TLC) and statistic analysis t test
uses. That mother pearl oysterââ¬â¢s at spawning time, LH (Luteinizing Hormone) grade the
high production (61.533 ppm/cc) and grade happen the descending 52.926 ppm/cc after
spawning a weekââ¬â¢s. The descend LH grade to pearl oysters is show that happen high
signification (8.607 ppm/cc whit tcalculate = 5,10 at 5% signification stage and ttable = 4,03.
The descending itââ¬â¢s quite possible that reach neutral period. The high grading of LH a sure
that indicate gonad growth of pearl oysters.
Key word: gonad, hormone, grade, spawning
