Pengaruh Karakteristik Penduduk dan Kadar Kadmium dalam Beras terhadap Kadar Kadmium Urine Penduduk di Kabupaten Musi Rawas Tahun 2014
ABSTRAK
Air Irigasi Tugumulyo yang digunakan untuk mengairi tanaman padi sawah di
duga tercemar logam berat kadmium dan logam kadmium ini dikhawatirkan dapat
mengakumulasi pada beras yang berasal dari tanaman padi sawah tersebut sehingga
membahayakan kesehatan masyarakat di Kabupaten Musi Rawas.
Tujuan penelitian, mengetahui pengaruh karateristik penduduk
(lama
konsumsi beras, lama tinggal, jenis kelamin) dan kadar kadmium dalam beras
terhadap kadar kadmium urine penduduk.
Jenis penelitian analitik korelasi dengan desain studi cross sectional . Waktu
penelitian bulan Januari-Juni 2014 dengan jumlah sampel : 23 sampel air, 23 sampel
beras, dan 46 orang sampel urine. Pemeriksaan Sampel air irigasi, sampel Beras dan
Sampel Urine dilakukan di Laboratorium LIDA MIPA USU.
Hasil penelitian Kadar kadmium dalam air irigasi 0,013-0,034 ml/l melebihi
baku mutu yang ditetapkan (0,01 ml/l) dan kadar kadmium dalam beras 0,013-0,019
mg/kg masih jauh di bawah ambang batas (0,4 mg/kg). Kadar Kadmium dalam urine
0,019-0,088 ml/l. Tidak ada perbedaan kadar kadmium urine berdasarkan jenis
kelamin, ada pengaruh lama konsumsi beras, lama tinggal dan kadar kadmium dalam
beras terhadap kadar kadmium urine penduduk. Lama konsumsi beras adalah variabel
yang paling dominan terhadap kadar kadmium urine. Secara keseluruhan variabel
mempengaruhi kadar kadmium dalam urine penduduk sebesar 64,6%.
Kadmium pada air irgasi di duga berasal dari pupuk maka Pemerintah
Kabupaten Musi Rawas diharapkan melakukan pengawasan peredaran pupuk yang
mengandung kadmium. Perlu penyuluhan pada petani tentang pemakaian dosis
pestisida dan pupuk yang baik dan benar sehingga dapat mencegah dan mengurangi
pencemaran logam berat dalam kandungan pupuk tersebut.

ABSTRACT
Tugumulyo irrigation water used to irrigate wet rice field is probably
contaminated by cadmium heavy metal which is feared to accumulate in the rice
which comes from this wet field rice so that it will endanger people’s health in Musi
Rawas District.
The objective of the research was to find out residents’ characteristics (the
length of consuming rice, the length of dwelling, and sex) and cadmium content in
rice on cadmium content in the urine of the residents in Musi Rawas District.
The research used analytic correlation study method with cross sectional design. It
was conducted from January to June, 2014 with the samples consisted of 24 water
samples, 23 rice samples, and 46 urine sample. The examining of the samples of
irrigation water, rice, and urine was conducted in LIDA Laboratory of MIPA, USU.
The result of the research showed that cadmium content in the irrigation
water was 0.013-0.034 ml/l, surpassed the quality standard of 0.01 ml/l, and
cadmium content in rice was 0.013-0.019 mg/kg, still far below the threshold of 0.4
mg/kg. Cadmium content in urine was 0.019-0.088 ml/l. There was the disparity of
urine cadmium content, based on sex, but there was the influence of the length of
consuming rice, the length of dwelling, and cadmium content in rice on cadmium
content in the residents’ urine. The variable of the length of consuming rice was the
most dominant influence on urine cadmium content. As a whole, the variable which
influenced cadmium content in the residents’ urine was 64.6%.
It is recommended that Musi Rawas District Administration should control
fertilizer distribution properly and correctly so thast the contaminatrion of heavy
metal can be avoided in its content.
