Abstract

High pollutant load from municipal discharges around the upstream of Citarum River contributes to the water quality problems of the river. Dynamic modelling was developed to analyze the behaviour of dissolved oxygen in upper of Citarum river using STELLA® as a tool. The modelling area consist of four segments namely Wangisagara, Jembatan Koyod, after Cisirung WWTP and Nanjung. Calibration and validation was done to get the most approaching simulated data to actual data. Average Mean Error (AME) and Average Variation Error (AVE) for all segments was 1.65% and 5.8%, therefore the developed model was valid. Sensitivity analysis shown that the dynamic of dissolved oxygen in upper of Citarum river was most affected by BOD load from municipal sources, decay coefficient of BOD (Kd), maximum rate of photosynthesis (pm) and fractional duration of daylight (f).

Abstract

This study aims to determine the effect of wind speed, humidity and air temperature on the concentration of SO2 in ambient air around PT. Medan Industrial Area (KIM) and to find out the description of SO2 concentration mapping around KIM. This study was limited to KIM Phase I and II and sampling was carried out at 6 (six) points. The results obtained were the lowest SO2 concentration of 58.63 µg / m3 and the highest concentration was 112.91 µg / m3. Based on the linear regression test, the result is that the higher the wind speed, the concentration of SO2 in the area around KIM is lower and 15.1% SO2 concentration is influenced by wind speed. The higher the humidity of the air, the concentration of SO2 in the area around KIM is lower and 26% of the concentration of SO2 is influenced by humidity. The higher the air temperature, the higher the concentration of SO2 in the area around the KIM and 68.5% the concentration of SO2 is influenced by air temperature. Based on the results of mapping using the Surfer 11 version, the results obtained in the morning the highest SO2 concentration was in the southern part of KIM and the lowest SO2 concentration was in the northwestern part of KIM. During the day, the highest SO2 concentration was in the eastern part of the KIM and the lowest SO2 concentration was in the northwestern part of KIM.

Abstract

Based on Onesta (2004) research, paper waste is the second largest waste component of Padang City's institutional waste, which is 23% after 52% of food waste. Paper comes from wood fiber which is a material that can be recycled, maximizing the potential for recycling will be able to increase efforts to preserve the environment and reduce environmental impacts. To assess the potential utilization of paper waste as recycled material, a study of the potential of paper waste recycling from institutions in the city of Padang is carried out through determining generation and composition. This research was conducted in August by taking a sample of 21 institutions (10 offices, 10 schools and 1 hospital) in accordance with SNI 19-3964-1994. From the research, it was obtained that the average waste generation of paper from institutional sources in Padang City was 0.048 l / m2 / hr where the waste generation of paper from office sources was 0.047 l / m2 / hr, school 0.059 l / m2 / h and hospitals 0.037 l / m2 / hr. For the composition of paper waste includes archival paper 44.73%, mixed paper 8.83%, cardboard and carton boxes 14.65%, 5.26% cardboard, 5.39% newspaper paper, 2.22% art paper, tissue 5.08%, carbon paper 0.15%, food wrappers 9.15% and others 4.55%. The potential of paper waste recycling is 78.88%, while that of not paper is 21.16%. To optimize the potential for paper recycling, it is recommended to separate paper waste from the source.

Abstract

Anaerobic digestion is to treat organic waste such as vegetable solid waste (VSW). Anaerobic co-digestion is the mixture of two or more different waste types with the aim to enhance the efficiency of the anaerobic digestion process. In this study, anaerobic digestion of vegetable solid waste (VSW) is compared to the anaerobic co-digestion of VSW and sequencing batch reactor (SBR) sludge. This investigation is focussed  on the varying the organic loading rate (OLR) which is the mixing ratio of VSW to SBR sludge; and pH (6, 7 and 8) of the mixture. The mixtures were kept in serum bottles and placed in a shaker for 7 days at 150 rpm. Experiments with OLR 2:1, VSW composition of 1:2:1:1 and pH 6 produced the highest total biogas in anaerobic co-digestion. Thus, for anaerobic co-digestion, the optimum composition of VSW, OLR and pH are 1:2:1:1, 2:1 and 6 respectively. The range of % reduction in total solids (TS), total suspended solids (TSS) and total dissolve solids (TDS) in anaerobic co-digestion is 4-46, 0-43 and 0-64 respectively. In a comparison with single digestion, only 1 in 5 samples of co-digestion exceed that amount of biogas produced by single digestion and this shows that single anaerobic digestion resulted in higher biogas yield. The range of % reduction in TS, TSS and TDS in anaerobic digestion is 13-54, 15-66 and 9-58 respectively. Comparatively, single digestion performs better in solids removal than anaerobic co-digestion and thus, co-digestion method may not be suitable for all types of organic waste.

Abstract

House dust mite is closely associated with the incidence of allergies such as asthma, atopic dermatitis and allergic rhinitis. Spesies of house dust mite which has been proven to be related with the incidence of allergies are Dermatophagoides pteronyssinus and Dermatophagoides farinae. The purpose of this study is to describe the density of house dust mites species  in residence houses in Kelurahan Jati. The study was a descriptive study with 96 samples taken from  two habitats, namely beds and carpets in 48 homes that have been selected randomly. House dust mites were identified using a light microscope with magnification of 40 times. The results showed that 56 of 96 samples were positive of house dust mites. This study showed that Dermatophagoides pteronyssinus was the most commonly found spesies of house dust mite (71 mites) with the highest density in the bed (6.88 mites/ gram of dust). Species Dermatophagoides farinae only found as many as 5 mites with the highest density in the carpet (0.46 mites/ gram of dust). The conclusion of this research is the density of house dust mites in Kelurahan Jati are quite low so that the possibility to cause allergic diseases is very small.

Abstract

Dissolved organic matter (DOM), which is part of of natural organic matter or NOM, contained of carbon compound and can cause problems related to taste, odor, and disinfection by-products (DBPs) in water and treated water. Permanganate is strong oxidant and have been know its efficiency in oxidazing organic compound. Coagulation is most widely used in all water treatment plant due to its efficiency in removing suspended solid. The objectives of this study is to characterize and to remove natural organic matter in term of  DOM  in water through KMnO4 preoxidation, Al2(SO4)3 or FeCl3 coagulation, KMnO4 preoxidation followed by Al2(SO4)3 or FeCl3 coagulation. Raw water, which was taken from Jagir River in Surabaya, and treated water were measured quantitatively by using total organic carbon (TOC), ultraviolet at wavelength 254 nm (UV254) in order to know its aromatic properties. In addition, fourier transfor m infrared spectroscopy (FTIR) was used to identify the functional group of DOM in water and treated water. The results showed that raw water has high TOC concentration (6,9 mg/L) and mainly composed of aromatic (UV254 0.075 cm-1). The optimum result showed that TOC concentration and UV254 removed significantly into 4,2 mg/L and 0,0020 cm-1, respectively after preoxidation followed by FeCl3 coagulation. According to FTIR analysis, mostly single bond carbon such as C-O and C-H still exist in treated water. This results indicated that preoxidation-coagulation has a better performance than preoxidation only and coagulation only.
