Abstract: Microalgae is the one of aquatic organism wich can be a bioindicators for surface water quality. Chlorophyll contain in a microalgae cell can be measured to know the abundance of microalga in a water body. Dry-weight biomass measurements is another method that can be used to know the abundance of microalga in a water body. both method have advantages and disadvantanges of each. In chlorophyll concentration measurements, the present of other compounds that can absorb light spectrum at measurements wavelength (Strickland and Parsons use 665 nm, 645 nm and 630 nm) result absorbance value higher than it should be. Turbidity level result by suspended particle content being a problem for dry-weight biomass measurements. Dry-weight biomass determination based on the approximation of chlorophyll content measurements was studied in this research. The Results of simple regression analysis showed that there is a fairly strong positive correlation between chlorophyll content and dry-weight biomass (Ra = 0.870), which has the tendency to follow the linear regression equation y = 302,35x + 17,121. Dry-weight determination based on approximation of clorophyll content can be applied to the sample of water that has suspended particle content tend to be constant and inert (did not produce subtances that can react with organic solvent when chlorophyll extraction process occurred). Based on the processed datas, it can be conclude that the influence of another suspended particle content in a sample of water is not statistically significant.

Saguling reservoir is an artificial reservoir located in West Bandung regency at an altitude of 643 m above sea level and serves to stem the Citarum River which is the largest river in West Java. Upper Citarum River has detected the organochlorine insecticide, one of them iss DDT. It is feared that DDT can accumulate in Saguling Reservoir which is the first dam to stem the Citarum River. This is very worrying given Saguling has greatly affect to the lives of many people. This study was conducted to estimate the fugacityvalue and concentration of DDT in each environmental compartment, such as in water, sediment, fish, aquatic plants, and mollusks by using Fugacity models. From calculation result, average DDT fugacity in the air is 3.23.10-14Pa, on the soil 2.73.10-17Pa, in the water 1.78.10-9 Pa, in sediments 9.64.10-10Pa. DDT concentration in the air compartment at Saguling Reservoir is 9,1.10-12ppm, on the ground 4,5.10-11ppm, in the water 6,9.10-4ppm, in sediments 0.99ppm, in the fish 0.013ppm, in the aquatic plant 0.005ppm, and in the mollusk 0.002ppm. Fugacity models are useful in predicting the distribution of DDT in each environmental compartment in Saguling Reservoir.

Publisher : President University

Pengelolaan sampah suatu kota bertujuan untuk melayani sampah yang dihasilkan penduduknya, secara tidak langsung turut memelihara kesehatan masyarakat serta menciptakan suatu lingkungan yang bersih, baik dan sehat. Saat ini pengelolaan persampahan menghadapi banyak tekanan terutama akibat semakin besarnya timbulan sampah yang dihasilkan masyarakat baik produsen maupun konsumen. Semua sampah dari sumber masing-masing akan bermuara ke tempat pemrosesan akhir sampah (TPA) Sumur Batu. Kecamatan Bantar Gebang merupakan daerah yang masuk wilayah Kota Bekasi dan memiliki dua lokasi TPA, yaitu milik Pemerintah Kota Bekasi di Sumur Batu dan yang satu milik DKI Jakarta di Bantar Gebang. Berdasarkan hal tersebut penulis memilih untuk melakukan penelitian terkait implementasi kebijakan dan strategi pengurangan sampah dari sumbernya. Dalam hal ini yang menjadi sumber penghasil sampah adalah kegiatan di Universitas Bhayangkara Jakarta Raya (UBJ) yang diperkirakan menghasilkan jenis sampah tertentu/khusus. Metodologi penelitian yang dilakukan adalah pengukuran langsung di lapangan dengan mengacu pada SNI 19-3964-1994 tentang metode pengambilan dan pengukuran contoh timbulan dan komposisi sampah. Hasil sampling diperoleh bahwa volume sumber sampah rerata 1,68 m3/hari (123,43 kg/hari). Secara umum komposisi persampahan UBJ yaitu 58,53% organik dan 41,47% an organik. Untuk sampah an organik, komposisi sampah yang dianggap berpotensi secara ekonomis terdiri dari 3 (tiga) jenis sampah dengan prosentase > 10% untuk bisa dimanfaatkan menjadi bahan bakar sintetis dan bahan kertas daur ulang. Bahan tersebut adalah Botol plastik 14,33%, Kertas 15,00% dan plastik lembaran 13,37% (jumlah sampah yang bisa dimanfaatkan 42,7%). Usulan tata kelola adalah dengan pemberdayaan unit kegiatan mahasiswa dalam pemilahan sampah yang bernilai ekonomis. Sedangkan untuk usulan teknis diharapkan bisa menampah space untuk area penerimaan, timbunan dan area pemilahan seluas ± 55 meter persegi.

APPLICATION OF ULTRAVIOLET (UV) TECHNOLOGY ON WATER DECHLORINATION: INFLUENCE OF UV FLUENCE DOSE AND UV TRANSMITTANCE ON CHLORINE REMOVAL EFFICIENCY Maryani Paramita Astuti; Xie Rongjing
Journal of Environmental Engineering and Waste Management Vol 1, No 1 (2016)
Publisher : President University

Water dechlorination is required to remove chlorine residual (free and combined chlorine) formed as byproducts of chlorination treatment. Ultraviolet (UV) dechlorination method has advantages compared to other dechlorination methods. This method uses a powerful photon energy generated by low pressure (LP) and medium pressure (MP) UV lamps to break chemical bond of the residual chlorine into reactive free radicals (•OH−) and (•Cl −). Studies are needed to evaluate its removal efficiency and the effect of treatment conditions on the efficiency before applying this method to practical applications. This study evaluates the effectiveness of medium pressure UV technology on UV dechlorination and investigates the influence of operation conditions (UV fluence and UV Transmittance) on chlorine removal efficiency. The impacts of both UV fluence and UV transmittance variations on chlorine removal efficiency were observed. Results of this study indicate that chlorine reduces upon exposure of UV radiation and chlorine removal efficiency increases with the increasing of UV fluence dose and UVT. The maximum UV fluence dose applied in this study (513 mJ/cm2) results in less than 25% of total chlorine reduction.
