ABSTRAKKromium merupakan logam berat yang dilarang penggunaannya dalam sediaan kosmetik. Efek logam kromium apabila terpapar pada kulit dapat menyebabkan dermatitis, oedema dan borok yang dapat meluas pada kulit. Analisis logam kromium (Cr) pada sediaan perona pipi (Blush On) secara Spektrofotometri Serapan Atom telah dilakukan. Masing-masing sampel didestruksi terlebih dahulu dengan cara destruksi kering, kemudian sampel dilarutkan dengan asam nitrat 6 N, larutan sampel diukur serapannya dengan alat Spektrofotometer Serapan Atom menggunakan lampu katoda berongga kromium pada panjang gelombang 357,9 nm. Hasil dari penelitian ini adalah sampel merek IZ, VV, KS, MC terdeteksi mengandung logam kromium dengan kadar berturut-turut adalah 10,05 ± 0,05 µg/g; 6,74 ± 0,02 µg/g; 28,95 ± 0,19 µg/g; 13,52 ± 0,63 µg/g. Data menunjukan bahwa adanya kromium pada semua sampel.Kata kunci: logam; kromium; perona pipi; spektrofotometri serapan atom ABSTRACTChromium is a heavy metal which is prohibited from using it in cosmetic preparations. Effects of chromium metal, when exposed to the skin, can cause dermatitis, oedema and ulcers that can extend to the skin. Analysis of chromium (Cr) metal in blush preparations by Atomic Absorption Spectrophotometry was carried out. Each sample was first destructed by dry destruction, then the sample was dissolved with 6 N nitric acid, the absorption of the sample solution was measured by an atomic absorption spectrophotometer using a chromium hollow cathode lamp at a wavelength of 357.9 nm. The results showed that all samples under the IZ, VV, KS and MC brands were detected containing chromium metal with levels of 10.05 ± 0.05 μg/g respectively; 6.74 ± 0.02 µg/g; 28.95 ± 0.19 µg/g; 13.52 ± 0.63 µg/g. Data shows that the presence of chromium in all samples.Keywords: metal; chromium; blush; atomic absorption spectrophotometry.

ABSTRAKLipstik merupakan salah satu kosmetik yang paling banyak dan hampir setiap hari digunakan oleh wanita. Timbal adalah salah satu cemaran logam berat yang terdapat dalam lipstik. Penelitian ini bertujuan untukmengetahui kandungan logam berat timbal dalam lipstik yang teregistrasi dan tidak teregistrasi mengguanakan Spektrofotometer Serapan Atom (SSA). Preparasi sampel menggunakan destruksi basah dengan aqua regia. Sampel lipstik yang digunakan sebanyak 24 sampel lipstik yang diambil di wilayah Kota Surabaya, dimana 12 sampel memiliki nomor registrasi BPOM dan 12 sampel tidak memiliki nomor registrasi BPOM. Hasil penelitian menunjukkan adanya kandungan logam berat yang melebihi persyaratan BPOM pada semua sampel lipstikdengan rata-rata kadar 108.9517 ppm untuk lipstik yang teregistrasi dan 102.7183 ppm untuk lipstik yang tidak teregistrasi. Berdasarkan uji Mann-Whitney U diketahui bahwa tidak ada beda antara kadar Pb pada lipstik yang teregistrasi dengan lipstik yang tidak teregistrasi dengan nilai α= 0,05.Kata kunci: Timbal (Pb), Lipstik, Surabaya, Registrasi, Spektrofotometri Serapan Atom. ABSTRACTLipstick is one of the most widely used cosmetics every day by women. Lead is one of the heavy metal contaminants found in lipstick. This study aims to determine the heavy metal content of lead in registered lipstickand not registered using Atomic Absorption Spectrophotometer (AAS). Sample preparation using wet destruction with aqua regia. Lipstick samples were used as many as 24 lipstick samples taken in the Surabaya area, where 12 samples had BPOM registration numbers and 12 samples did not have BPOM registration numbers. The results showed that there was a heavy metal content that exceeded BPOM requirements for all lipstick samples with an average level of 108.9517 ppm for registered lipstick and 102.7183 ppm for unregistered lipstick. Basedon the Mann-Whitney U test it is known that there is no difference between Pb levels on lipstick registered with lipstick which was not registered with a value of α = 0.05.Keywords: Lead (Pb), Lipstick, Surabaya, Registration, Atomic Absorption Spectrophotometry..

Lipstick or lip dye is a cosmetic dose that serves to coloring, decorative the lips, as a moisturizing material and protect the lips from exposure the sun to provide optimum results. Lipstick should not contain chemicals such as lead (Pb) because the Pb is a heavy metal that is very dangerous when continuously used on the skin, because it will be absorbed into the blood and attack the body organ causing the onset of disease. According to BPOM that the lead rate on the lipstick does not exceed the permissible limit of 20 mg/kg or 20 ppm.This research aims to know the levels contained in the samples are 4 brands of matte lipstick that are sold in the Aceh market in Banda Aceh City with the method of atomic absorption spectrophotometry (AAS). The results showed that on the 4 brands of lipstick matte contain heavy metal lead (Pb) with a rate still qualified allowed by BPOM  is samples A, B, C, and D, respectively at 0.24 ppm; 0.10 ppm; 2.87 ppm and 1.32 ppm, so that the 4 brands of lipstick matte are still used.

Logam berat Fe merupakan logam berat essensial yang keberadaannya dalam jumlah tertentu sangat dibutuhkan oleh organisme hidup, namun dalam jumlah yang berlebih dapat menimbulkan efek racun.Penelitian ini bertujuan untuk menganalisis kandungan dan tingkat pencemaran logam berat Fe pada air, sedimen, dan kerang hijau (Perna viridis) di perairan Tanjung Emas Semarang. Penelitian ini dilaksanakan pada tanggal 7 November dan 7 Desember 2013 dengan metode penelitian deskriptif. Logam berat Fe dalam sampel air, sedimen dan kerang hijau dianalisis di Laboratorium Balai Besar Teknologi Pencegahan Pencemaran Industri (BTPPI) Semarang dengan menggunakan metode AAS (AtomicAbsorption Spectrophotometry). Hasil penelitian menunjukkan bahwa perairan Tanjung Emas masih dalam taraf terkontaminasi logam Fe. Sedangkan pada sedimen dan pada kerang hijau (Perna viridis) sudah terindikasi tercemar logam Fe.Meskipun demikian variasi faktor lingkungan seperti suhu, salinitas, pH, kecepatan arus dan jenis sedimen juga memberikan kontribusi yang cukup penting terhadap kandungan logam Fe.Kata Kunci: logam Fe, Air, Sedimen, Perna viridis, metode AAS Heavy metalsiron(Fe) is anessentialheavy metalswhose presencein a certain amountis neededby living organisms, but inexcessiveamountscan causetoxic effects.The aims of the research is to analyze the heavy metals coccentration and the pollution level of Fe in water, sediment, and green mussels (Perna viridis) at Tanjung Emas Semarang.

Abstract We describe an integrated automated system for the atomic absorption spectrophotometer. The system makes use of a light-dependent resistor to detect the presence of a marker ion which is present along with the sample ion in the flame. An electronic circuit has been developed which enables the marker ion to trigger the read signal of the spectrophotometer. The system has been tested by determining magnesium and calcium in serum. Alternative modes of operation and different potential applications are discussed.
