ABSTRACT
The growing population and the rapid economic development have led an increasing input of waste waters mainly from industries, agriculture and households into marine environment. In addition, discharge of maritime transportation and accidents of soil spills contribute to the marine as pollutants. The released compounds have dangerious effects, for example hazard to human health, hindrance to marine activitities, and impairmentof the quality of seawaters. Because of hydrophobic character, these compound contaminants tend to be adsorbed to sediment particles and therefore it could be considered as pollution reservoirs. They are also accumulated in the aquatic organism and biomagnified in the food chains. Some contaminants pose a health risk to aquatic organisms and ultimately to humans who consume contaminated seafood. Therefore, study of activated carbon dsorption will reduce organic pollution such as PAH in marine environment.

Ikan merupakan komoditi pangan dengan kandungan protein yang tinggi, tetapi ikan mudah sekali menjadi busuk. Pengawetan Ikan Bandeng Asap secara radiasi dapat membantu mencegah kerusakan pangan karena mempunyai berbagai keuntungan, yaitu ikan bandeng asap dapat disimpan pada suhu ruang dengan jangka waktu yang relatif lama. Pada penelitian ini bertujuan untuk mengawetkan ikan bandeng asap agar dapat disimpan pada suhu ruang, selain itu dilihat pengaruh radiasi terhadap pembentukan senyawa MDA (Malondialdehid), PAH (Polisiklik Aromatik Hidrokarbon), dan Radikal bebas dengan variasi waktu simpan 0 minggu, 4 minggu, 12 minggu. Hasil yang didapat dari pengolahan data menggunakan ANOVA bahwa untuk PAH dosis radiasi dan lama simpan tidak mempengaruhi konsentrasi PAH. Sedangkan pada MDA, di bagian daging bandeng dosis radiasi dan masa simpan mempengaruhi konsentrasi MDA. Untuk tulang dan kulit dosis radiasi dan masa simpan tidak mempengaruhi konsentrasi MDA. ......Preservation of MilkFish, by ionizing radiation, has been shown to effectively reduce food spoilage so it can be stored in room temperature with a much long period. This review aims at summarizing all available information regarding the impact of irradiation dose on the formation of malondialdehid (MDA), polyaromatic hydrocarbon (PAH), and free radical with store period 0 week, 4 week, and 12 week. The result from these treatment, by using analysis of variance (ANOVA), is that radiation doses and store period does not impact PAH concentration in fish while MDA does. For bone and skin, the radiation dose and store does not impact on MDA concentration.

There is an information how to identify hydrocarbon degrading bacteria for bioremediation of marine oil spill. We have Bioremediation treatment for degradation of oil spill on Pari island and need two kind of experiment there are tanks experiment (sampling 0 to 90 days) and semi enclosed system (sampling 0 to 150 days). Biostimulation with nutrients (N and P) was done to analyze biodegradation of hydrocarbon compounds. Experiment design using fertilizer Super IB and Linstar will stimulate bacteria can degrade oil, n-alkane, and alkane as poly aromatic hydrocarbon. The bacteria communities were monitored and analyzed by Denaturing Gradient Gel Electrophoresis (DGGE) and Clone Library; oil chemistry was analyzed by Gas Chromatography Mass Spectrometry (GCMS). DNA (deoxyribonucleic acid) was extracted from colonies of bacteria and sequence determination of the 16S rDNA was amplified by primers U515f and U1492r. Strains had been sequence and had similarity about 90-99% to their closest taxa by homology Blast search and few of them suspected as new species. The results showed that fertilizers gave a significant effect on alkane, PAH and oil degradation in tanks experiment but not in the field test. Dominant of the specific bacteria on this experiment were Alcanivorax, Marinobacter and Prosthecochloris.

ABSTRAK
The goal of the study is to review changes in dryland farming culture of atoni pah meto in North Center Timor District caused by global climate changes. The research method used was qualitative descriptive: the data collecting method used was interviews, observations, and the document study. Research results prove that the atoni pah meto which consists of eighteen farming rituals, five work patterns, work division between genders, and work ethos, has shifted. It is caused by the interaction of atoni pah meto with other nations, tribes, and ethnic groups, further affected by global climate changes. Climate changes have made a great impact on farmer?s existence and culture. Because of that, the atoni pah meto of NCT District must open up more by accepting changes in the form of program intervention from the governmental and private institutions. It is time to leave shifting cultivation and slash and burn culture, and move to nature friendly farming technologies. Sickle culture will be offered here to replace slash and burn culture, supported by technologies, a more efficient work pattern and work division, and high work ethos, and it is expected that dryland farming of atoni pah meto will persevere.

Kebakaran hutan dan lahan menghasilkan asap yang diketahui mengandung Polycyclic Aromatic Hydrocarbon (PAH). Efek adanya kerusakan oksidatif pada DNA akibat paparan asap kebakaran hutan dan lahan terhadap risiko kanker diselidiki melalui deteksi biomarker 8-Hidroksi-2’-Deoksiguanosin (8-OHdG) dan 1-Hidroksipiren (1- OHP), metabolit utama piren, sebagai indikator paparan PAH dalam urin. Analisis biomarker paparan PAH dalam urin 24 jam dilakukan secara acak dalam suatu populasi di Kota Dumai, Provinsi Riau. Kandungan 8-OHdG dalam sampel urin dianalisis menggunakan HPLC detektor UV dengan fasa gerak buffer natrium fosfat 0,1 M pH 6,7 dan metanol (85:15, v/v). Sementara, kandungan 1-OHP dalam urin dideteksi menggunakan HPLC detektor flourosens dengan eluen metanol dan air (60:40, v/v). Analisis kedua senyawa tersebut dilakukan dengan kromatografi fasa terbalik mode isokratik. Hasil pengujian menunjukan bahwa 8-OHdG terdeteksi pada seluruh sampel dalam rentang konsentrasi 25,29 g/L hingga 2,16 mg/L urin (n = 11), lebih tinggi dibandingkan dengan konsentrasi 8-OHdG dalam urin individu sehat (1,42 μg/L – 4,25 μg/L). 1-OHP dalam urin juga terdeteksi dalam empat dari lima sampel yang diuji, menandakan bahwa terdapat potensi besar kerusakan oksidatif DNA akibat paparan PAH......orest fires generate woodsmoke that contain Polycyclic Aromatic Hydrocarbon (PAH). The effect of DNA oxidative damage due to woodsmoke exposure on cancer risk can be investigated through the detection of urinary 8-Hydroxy-2’-Deoxyguanosin (8-OHdG) and 1-Hydroxypyrene, main metabolite of pyrene, as indicators of PAH exposure. Analysis biomarkers of PAH exposure in 24 hours urine was performed within a population randomized in Dumai City, Riau Province. The 8-OHdG levels in urine samples were analyzed by using HPLC with UV detector using sodium phosphate buffer 0.1 M pH 6.7 and methanol (85:15, v/v) as mobile phase. Meanwhile, 1-OHP levels in urine was detected by using a HPLC with fluorosens detector using methanol and water (60:40, v/v) eluent. Analysis of both compounds was performed by reverse phase chromatography with isoratic mode. The results showed that 8-OHdG was detected in all samples with concentration range of 25.29 μg/L to 2.16 mg/L urine (n = 11), higher than urinary 8-OHdG of health person (1,42 μg/L – 4,25 μg/L). Urinary 1- OHP was also detected in four of five samples. It indicates that there was a high potential of DNA damage caused by PAH exposure
