The 8-isoprostane compound can be used for a biomarker of oxidative stress formed by lipid peroxidation in the form of arachidonic acid with free radical in the body. The purpose of this study was to analysis urinary 8-isoprostane in male Wistar rats after sub-acute exposer to ethanol and cigarette smoke. Extraction method used was solid phase extraction and the analysis was conducted by TLC and spectrophotodensitometry. The results showed that the 8-isoprostane compound was not detected in the male Wistar rat’s urine as control rats and in those exposed to cigarette smoke. The average concentrations of 8-Isoprostane in the male Wistar rat’s urine exposed to ethanol and combination of ethanol-cigarette were 1.519 ± 1,386 and 2.063 ± 1,308 ppm respectively.

The application of water reclamation system has been researched for the concentration of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) in the effluent waste water treatment in Suwung Denpasar. The aims of the research were to determine the effect of each stage of water reclamation system on the BOD5 and COD of the effluent, the effectiveness of the water reclamation system and the quality of the reclaimed water. The results showed that each stage of water reclamation system can decrease the concentrations of BOD5 and COD from waste water treated with different percentage of reduction. The percentages of the COD reduction by first stage (biological filtration systems) were 41.17% and 31.23% respectively BOD5 and COD. The second stage (pre-ozonation system) were 83.13% and 77.68% respectively. Moreover, the third stage (coagulation and membrane systems) reduced 29.25% and 8.02% respectively. The overall rate of effectivenes from the initial to final stages of waste water reclamation were 92,98% for BOD5 and 85,88% for COD.

Fatty acid ethyl ester (FAEE) merupakan salah satu biomarker konsumsi etanol. Penelitian ini bertujuan untuk menganalisis senyawa FAEE dalam sampel rambut secara kualitatif dengan GC-MS. Pada penelitian ini dibuat campuran standar FAEE (Etil Pamlitat dan Etil Oleat) 100 ppm dengan perbandingan 1:1 kemudian dibuat variasi konsentrasi. Metode validasi standar FAEE diukur menggunakan GC-MS. Sampel rambut dipreparasi dengan cara didekontaminasi kemudian diekstraksi dan diinjeksikan ke sistem GC-MS. Hasil validasi diperoleh persamaan regresi linier yaitu, y = 240713,507x-147471,2353 untuk etil palmitat dan y = 58361,45x+242,5 untuk etil oleat dengan nilai koefisien korelasi (r2) berturut-turut sebesar 0,9996 dan 0,9999. Batas deteksi diperoleh sebesar 2,5522 ppm dan 0,0189 ppm, dengan batas kuantitasi sebesar 8,5073 ppm dan 0,0630 ppm. Nilai koefisien variansi diperoleh sebesar 3,59% dan 8,65 x 10-4%, dengan persen perolehan kembali sebesar 100,05% dan 100,08%. Hasil analisis menunjukkan, sampel rambut semua sukarelawan mengandung etil palmitat dan etil oleat pada waktu retensi 22,03 menit dan 23,83 menit.

Paracetamol (acetaminophen) is one of analgesic-antipyretic drugs which can be commercially obtained. The research aimis to analyze qualitatively the presence of paracetamol (acetaminophen) in urine and human hair by gas chromatography-mass spectrometry (GC-MS). Urine and human hair sample were obtained from patients (volunteers) who consume paracetamol in therapeutic dose without consumption patterns change. Extraction of paracetamol in urine used ethyl acetate and in human hair used methanol. The extract was then derivatized with BSTFA and 1% TMCS and analyzed using gas chromatography-mass spectrometry (GC-MS). The result showed that urine samples after 1, 2, and 3 hours consuming paracetamol contained acetaminophen-TMS. Those after 24, 168, and 720 hours after consuming paracetamol did not contain acetaminophen-TMS. In human hair, the acetaminophen-TMS was found in samples of 1, 2, 3, 24, 168, and 720 hours after consuming paracetamol.

Ethanol is an alcohol which is in particular concentration allowed existing in beverages. One of alcoholic beverages that is popular in Bali is arak. This kind of beverage may contain ethanol in various concentrations depending on the distillation process carried out. The aim of this study was to detect the alcohol contents in urine collected from some volunteer who have consumed arak for two weeks with the technique of Gas Chromatography Flame Ionization Detector (GC-FID). The standard solutions employed were methanol, ethanol and acetic acid, while buthanol was used as the internal standard solution. The urine samples were collected in various sampling times after two weeks arak consumption. The ethanol contents obtained after 4, 8, 12, 16, 28, and 20 hours from the last consumption were (8.86 – 8.98) x 10-2 , (8.06 – 8.46) x 10-2, (8,81 – 8.93) x 10-2, (7.47 – 7.73) x 10-2, (8.76 – 8.89) x 10-2, and (8.15 – 8.27) x 10-2% (b/v), respectively.

Penelitian ini tentang pengujian kapasitas antioksidan dan kandungan fenolik total sari buah mengkudu terfermentasi dengan penambahan sari jahe dan gula merah. Tujuan penelitian ini adalah untuk menganalisis perubahan kapasitas antioksidan dan kandungan fenolik total dalam sari buah mengkudu sebelum dan setelah difermentasi selama beberapa hari. Kapasitas antioksidan dalam sari buah mengkudu semakin kecil setelah fermentasi yaitu dari 38,10 mgGAE/100 g (sebelum ditambahkan sari jahe, gula merah, tanpa difermentasi) menjadi 30,18; 28,68; dan 23,97 mgGAE/100 g berturut-turut setelah 2, 4, dan 6 hari fermentasi. Penurunan juga terjadi pada kadar fenolik total yaitu dari 54,46 menjadi 45,54; 39,39; dan 34,82 mgGAE/100 g.
