ANALISIS KADAR LOGAM BESI (Fe) PADA AIR SUMUR BOR DI KECAMATAN PRAYA TENGAH MENGGUNAKAN SPEKTROFOTOMETRI SERAPAN ATOM

---

ABSTRAK
Penelitian bertujuan untuk menganalisis kadar logam Fe pada air sumur
bor di Kecamatan Praya Tengah dengan menggunakan spektrofotometri serapan
atom. Penelitian ini dilaksanakan di laboratorium kimia Analitik Fakultas MIPA
Universitas Mataram dan Laboratorium Farmasi. Menggunakan metode Purposive
sampling mengutamakan kriteria dilihat dari keadaan fisik air yaitu pemilihan
sampel berdasarkan uji warna, rasa, bau, suhu dan pH untuk analisis kualitatif
dan uji kuantitatif untuk mengetahui kadar logam berat Besi (Fe) menggunakan
metode spektrofotometri serapan atom (SSA). Hasil secara kualitatif menunjukkan
sampel air sumur di Desa Jontlak dan Batunyala hasil pH (6), suhu (26oC), warna
bening agak kekuningan dan tidak memiliki bau, sampel di Desa loang sawak
memiliki pH (6,5), suhu (26), warna bening dan tidak berbau. Hasil sampel air
sumur bor Desa Jontlak, Desa Loang Sawak dan Desa batunyala teridentifikasi
positif mengandung logam besi. Hasil pengukuran kadar Fe di Desa Jontlak
1,4713 mg/L, Desa Loang Sawak 4,0191 mg/L dan Desa Batunyale 4,2738 mg/L.
Jadi hasil ketiga desa . Jadi hasil ketiga desa yang melebihi standar kepmenkes RI
tahun 2002 yaitu 0,3 mg/L pengawasan kualitas air minum dan PERMENKES RI
tahun 2017 yaitu 1 mg/L air untuk keperluan higiene sanitasi.
Kata Kunci : sumur bor, logam besi (Fe), uji kualitatif dan kuantitatifviii
ABSTRACT
The aim of the study was to analyze the metal content of Fe in drilled well
water in Praya Tengah District by using atomic absorption spectrophotometry.
This research was conducted in the Analytical chemistry laboratory, Faculty of
Mathematics and Natural Sciences, University of Mataram and the Pharmacy Laboratory. Using the purposive sampling method, prioritizing the criteria seen from
the physical state of the water, namely the selection of samples based on color,
taste, odor, temperature and pH tests for qualitative analysis and quantitative tests
to determine the levels of heavy metal Iron (Fe) using the atomic absorption spectrophotometry (AAS) method. Qualitative results showed that samples of well water in Jontlak and Batunyala villages had pH (6), temperature (26oC), a slightly
yellowish clear color and had no odor, samples in Loong sawak Village had a pH
(6.5), temperature (26), clear color and odorless. The results of the measurement
of Fe levels in Jontlak Village were 1.4713 mg/L, Loang Sawak Village was
4.0191 mg/L and Batunyale Village was 4.2738 mg/L. So the results of the three
villages. So the results of the three villages that exceed the standards of the Ministry of Health of the Republic of Indonesia in 2002 are 0.3 mg/L for monitoring the
quality of drinking water and the PERMENKES RI in 2017 which is 1 mg/L of
water for sanitation hygiene purposes.
Keywords: bore well, ferrous metal (Fe), qualitative and quantitative test.
