Penelitian bertujuan untuk menilai kualitas Sungai Cibareno di Banten, Jawa Barat. Penelitian dilakukan dengan menyatakan hasil identifikasi makrozoobentos sebagai bioindikator yang diambil dari 9 stasiun penelitian di Sungai Cibareno. Analisis makrozoobentos dalam rangka pemantauan kualitas Sungai Cibareno menggunakan Biological Monitoring Working Party - Average Score per Taxon (BMWP - ASPT) pada tingkat famili atau kelompok makrozoobentos berdasarkan toleransinya terhadap cemaran. Hasil penelitian menunjukkan bahwa bagian hulu, tengah, dan hilir sungai Cibareno berturut - turut memiliki nilai ASPT sebesar 5,3, 5,5 dan 4,8. Secara keseluruhan Sungai Cibareno memiliki nilai ASPT 5,2 dan termasuk dalam tingkat pencemaran ringan. ......The main objective of this study was to assess the quality of Cibareno River in Banten, West Java. The research was conducted by explain the result of identification of macrozoobenthos as the indicator which taken form 9 research stations in Cibareno River. The analysis of macrozoobenthos in order to monitor the quality of Cibareno River is using Biological Monitoring Working Party - Average Score per Taxon (BMWP - ASPT) on the family level or groups of macrozoobenthos based on the tolerance of the organism against pollutant. The result showed that the head, the middle and the downstream of Cibareno River has the ASPT score about 5,3, 5,5 and 4,8. The entire score of Cibareno River is 5,2 and it means that the pollutant level is low.

Penelitian mengenai kualitas air Ciliwung telah dilakukan di tiga stasiun yang merepresentasikan bagian yang masih alami, wilayah yang sudah dilakukan penataan dan yang sudah di normalisasi pada bulan September hingga November 2017. Penelitian ini bertujuan untuk mengetahui nilai kualitas perairan Sungai Ciliwung perbatasan Depok dan Jakarta Selatan berdasarkan makrozoobentos dan dianalisis menggunakan metode Biological Monitoring Working Party - Average Score Per Taxon BMWP - ASPT. Parameter lingkungan juga turut diukur dalam penelitian ini. Hasil penelitian didapatkan 22 famili makrozoobentos antara lain Chironomidae, Tubificidae, Buccinidae, Physidae, Lymnaidae, Planorbidae, Thiaridae, Viviparidae, Ampularidae, Palaemonidae, Parathelpusidae, Corbicullidae, Lestidae, Lindeniidae, Libellulidae, Aeshinidae, Corduliidae, Erpobdellidae, Hydropsychidae, Glossiphonidae, Hymenosomatidae, Dugesiidae. Sungai Ciliwung perbatasan Depok - Jakarta Selatan memiliki kisaran nilai ASPT 3 ndash; 4,87 yang mengindikasikan bahwa kondisi perairan tergolong dalam kualitas perairan agak buruk hingga sangat buruk.

A research of water quality test in Ciliwung has been conducted at three stations representing the unconstructed area, settlement area and normalization area from September until November 2017. This research aimed to determine the quality of Ciliwung River across Depok ndash South Jakarta using makrozoobentos as bioindicator through Biological Monitoring Working Party Average Score Per Taxon BMWP ASPT method. Environmental parameter also measure. The results obtained were twenty two families of makrozoobentos namely Chironomidae, Tubificidae, Buccinidae, Physidae, Lymnaidae, Planorbidae, Thiaridae, Viviparidae, Ampularidae, Palaemonidae, Parathelpusidae, Corbicullidae, Lestidae, Lindeniidae, Libellulidae, Aeshinidae, Corduliidae, Erpobdellidae, Hydropsychidae, Glossiphonidae, Hymenosomatidae, Dugesiidae. Ciliwung River across Depok ndash South Jakarta has ASPT range between 3 ndash 4,87 which classified as poor quality water.

Asap kebakaran hutan mengandung senyawa karsinogenik yang dapat menghasilkan spesi oksigen reaktif melalui proses metabolisme di dalam tubuh. Spesi oksigen reaktif yang terbentuk dapat berinteraksi dengan makromolekul seperti DNA, sehingga menyebabkan kerusakan oksidatif DNA. Penelitian ini dilakukan untuk menganalisis pengaruh paparan asap kebakaran hutan terhadap pembentukan senyawa DNA adduct 8-OHdG menggunakan HPLC fase terbalik dengan detektor UV pada panjang gelombang 254 nm. Fase gerak yang digunakan berupa campuran natrium fosfat 0,1 mol/L pH 6,7 dan metanol (85:15, v/v). Hasil penelitian menunjukkan bahwa paparan asap kebakaran hutan meningkatkan konsentrasi 8-OHdG dalam urin korban kebakaran hutan dengan konsentrasi sebesar 2,76 ± 1,94 ppm. Penelitian ini juga dilakukan untuk menganalisis senyawa S-PMA dalam urin korban kebakaran hutan sebagai biomarker spesifik paparan benzena. Senyawa S-PMA dianalisis menggunakan LC-MS/MS dengan fase gerak berupa diklorometana yang mengandung asam asetat 1%. Hasil penelitian menunjukkan bahwa senyawa S-PMA terdeteksi di dalam urin korban kebakaran hutan dengan konsentrasi sebesar 0,011 ± 0,01 ppb, sehingga mengindikasikan adanya benzena di dalam asap kebakaran hutan tersebut.
Forest fire wood smoke contains carcinogenic compounds that can produce reactive oxygen species through metabolic processes in the human body. The reactive oxygen species formed can interact with macromolecules such as DNA, thus causing oxidative damage to DNA. This study was conducted to analyze the effect of forest fire wood smoke exposure on the DNA adduct 8-OHdG formation using reverse-phase HPLC with a UV detector at a wavelength of 254 nm. The mobile phase used was a mixture of 0.1 M sodium phosphate pH 6.7 and methanol (85:15, v/v). The result showed that forest fire wood smoke exposure increased the concentration of 8-OHdG in the urine of forest fire victims with a concentration of 2.76 ± 1.94 ppm. This study was also conducted to analyze S-PMA compounds in the urine of forest fire victims as a specific biomarker of benzene exposure. S-PMA compound was analyzed using LC/MS-MS with dichloromethane containing acetic acid 1% as a mobile phase. The result found that the S-PMA compound was detected in the urine of forest fire victims with a concentration of 0.011 ± 0.01 ppb that indicating the presence of benzene in forest fire wood smoke.
