Abstract


ABSTRACT
This study aimed to determine the macro and micro mineral content of mangrove fruits (A. lanata, B. gymnorrhiza,
and X. moluccensis). The samples used in this study were A. lanata, B. gymnorrhiza, and X. moluccensis mangrove plants
which were taken fresh and ripe. Preliminary analysis of the micro mineral content of A. lanata, B. gymnorrhiza, and X.
moluccensis mangroves was processed into a dry powder weighing 0.5 g of each sample. The fruit was mixed with a
solution of HNO
3
and 30% H
2
O
2
. Sodium (Na), Potassium (K), and Calcium (Ca) levels were analyzed using a flame
photometer. The micro-mineral content of A. lanata, B. gymnorrhiza, and X. moluccensis types were analyzed for iron (Fe),
copper (Cu), manganese (Mn), and zinc (Zn) using the atomic absorption spectrophotometer. The results show that the
macro-mineral content (sodium, potassium, and calcium) of the fruits of the three types of mangroves were significantly
different, where X. moluccensis showed the highest levels of macro minerals compared with mangrove fruits of B.
gymnorrhiza and A. lanata. Micro mineral content (Iron and Zinc) of X. moluccensis was higher than B. gymnorrhiza and A.
lanata while copper and manganese levels of B. gymnorrhiza mangrove were higher than X. moluccensis and A. lanata.

ABSTRAK
Penelitian ini bertujuan untuk mengetahui kandungan mineral makro dan mineral mikro buah mangrove (A. lanata,
B. gymnorrhiza dan X. moluccensis). Sampel yang digunakan dalam penelitian ini yaitu tumbuhan mangrove jenis A. lanata,
B. gymnorrhiza dan X. moluccensis yang diambil dalam keadaan segar dan matang. Awal analisis kadar mineral mikro buah
mangrove jenis A. lanata, B. gymnorrhiza dan X. moluccensis diolah menjadi bubuk kering dengan berat 0,5 g sampel
setiap yang buah dicampur dengan larutan HNO
3
dan 30% H
2
O
2
. Kadar Sodium (Na) dan Kalium (K) maupun Kalsium (Ca)
dianalisis menggunakan flame fotometer. Kadar mineral mikro buah mangrove jenis A. lanata, B. gymnorrhiza dan X.
moluccensis, dilakukan analisis kadar Besi (Fe), tembaga (Cu), mangan (Mn) dan Seng (Zn), menggunakan instrumen
spektrofotometer serapan atom. Hasil penelitian menunjukkan bahwa Kadar mineral makro (Sodium, Kalium dan Kalsium)
buah dari tiga jenis mangrove berbeda signifikan, dimana X. moluccensis menunjukkan kadar mineral makro paling tinggi
dibandingkan dengan buah mangrove B. gymnorrhiza dan A. lanata. Kadar mineral mikro (Besi dan Seng) mangrove X.
moluccensis lebih tinggi dibandingkan B. gymnorrhiza dan A. lanata sedangkan kadar tembaga dan mangan buah
mangrove B. gymnorrhiza lebih tinggi dibandingkan dengan buah mangrove X. moluccensis dan A. lanata.
Kata Kunci: Mineral Makro dan Mikro, Buah Mangrove, Bahan Pangan
