<![CDATA[Tangerang City is one of the cities in Banten Province. The dense population causes an increase in the volume of waste, so an adequate Solid Waste Facility (SWF) is needed. Solid Waste Facility is the place to process and return the waste to the environment. Rawa Kucing SWF is one that serves Tangerang City with an area of 37.7 hectares, divided into four landfill zones and landfill support facilities. With the remaining land that can be used to build a new landfill, it is necessary to conduct a study on the feasibility of Rawa Kucing SWF if it is still feasible as seen by the environmental conditions or not. In the Regulation of the Minister of Public Works Number 3 of 2013, there is a land suitability assessment for taking decision of SWF whether it is to be rehabilitated or should be closed known as the Integrated Risk Based Approach (IRBA). The result of the environmental risk index assessment based on IRBA is 599.03, which means that mean Rawa Kucing SWF is included in moderate hazard category. The recommended action in this category is that the TPA is continued and rehabilitated into gradually controlled landfill. Currently, the Rawa Kucing SWF has applied controlled landfill method, so the effort to develop the landfill method into sanitary landfill method can be done gradually to reduce adverse impact to the environment. Technology such as Waste-to-Energy (WtE) Plants can also be considered to reduce the waste load entering the landfill.]]>

<![CDATA[Source of raw water used at Badak Singa Water Treatment Plant come from surface water such as Cisangkuy River. This source of raw water is affected by conditions in the upstream, pollution along the stream, climate and weather. In the drinking water supply system, turbidity is one important factor for several reasons such as aesthetic factor, burden to filtration, and interfere the disinfection process. Electro coagulation is one of water treatment method that combines the process of coagulation, flotation, and electrochemical. Aims: This research aims to see at the ability of the electro coagulation process in reducing turbidity as an alternative to substitute the conventional coagulation system. Methodology and results: This research carried out by testing electro coagulation with variations in mixing, current density produced by voltage 10, 20 and 30 volt and detention time 5, 10, 20 and 30 minute to reduce the initial turbidity of 100 NTU. The result are that: the efficiency of electro coagulation with mixing is better than electro coagulation without mixing to reduce the initial turbidity of 100 NTU; the final turbidity value of the processing result is better as the length of detention time used and meet the quality standard from detention time of 10 minute; the higher the current density given and the longer the detention time used, the higher the processing efficiency and the formed flock volume is deposited. Conclusion, significance and impact study: A good turbidizing removal process using electrocoagulation requires the agitation process and long detention time.]]>

<![CDATA[Aims: This planning aims to obtain the optimum flush volume on the design of sewerage in South Tangerang City. Methodology and results: Factors affecting this flushing are the length of pipelines, the service area, and topographic conditions. The sewer drain that needs flushing is Line 1–WWTP since the minimum velocity is not eligible due to its relatively low average topographic slope. The flushing is required particularly for the Section 1–2. Hence, two alternatives were devised by dividing the Population Equivalent (PE) in Section 1–2 into three segments. Those alternatives were differentiated by the PE—20%, 5%, and 75% for Alternative 1; whereas 10%, 15%, and 75% for Alternative 2. Alternative 1 requires flushing on Section 1–1.1 since it has a dmin of 7 cm and vmin of 0.2585 m/s, yielding a flush volume of 3.94 m3 (0.0193 m3/s). Section 1.1–1.2 still needs flushing because this channel has a vmin of 0.4281 m/s and a qualified dmin of 15 cm, generating a flush volume of 7.89 m3 (0.2113 m3/s). Flushing is not necessary for Section 1.2–2 due to its sufficient dmin of 63 cm and vmin of 0.88 m/s. Alternative 2 requires flushing on Section 1–1.1 since it has a dmin of 7 cm and a vmin of 0.2585 m/s, resulting in a flush volume of 2.63 m3 (0.0193 m3/s). Section 1.1–1.2 still requires flushing on account of its vmin of 0.3877 m/s and the yielded flush volume of 18.4 m3 (0.2625 m3/s), though its dmin of 13 cm complies with the standard. Section 1.2–2 does not need flushing as it already has a dmin of 63 cm and a vmin of 0.88 m/s. The total flush volumes for Alternative 1 and Alternative 2 are 11.83 m3 and 21.04 m3, respectively. Conclusion, significance, and impact of the study: The total flush volume for Alternative 1 is 11.83 m3, while Alternative 2 is 21.04 m3. Thus, the optimum design having the least flush volume is Alternative 1.]]>

<![CDATA[Aims: This study aims to analyze and select wastewater treatment technology that can be applied to riverbank settlement areas through environmental impact evaluation using LCA. The technology option is selected through the physical condition of the settlement environment on the river banks and then analyzed descriptively by making a flow chart of the processing technology options and compared with the wastewater treatment technologies that have been applied to residential areas of river banks or other swamp settlements. Methodology and results: The technology options will be analyzed and evaluated for potential environmental impacts of the construction and operation phase, using LCA through SimaPro8.4 software with an impact analysis using CML2 Baseline 2000. The impacts analyzed include acidification, eutrophication, global warming, ozone depletion. The results showed that the selected technological options were septic tanks, tripikon-s, and biofilter. In an environmental impact analysis it is known that the construction phase is a phase that contributes greatly to the potential environmental impacts. The potential for acidification and global warming are the dominant potential impact from the three technology options, with a contribution of 2.01x10-10 kgSO2-eq for the potential of acidification and 1.11x10-10 kgCO2-eq for global warming potential with biofiltration as a main contributor. The eutrophication potential is caused by nutrients (Total Nitrogen and Phosphorus) that come out along with the treated wastewater at the operating stage. The greatest eutrophication potential is generated on the Tripikon-S, at 2.3x10-10 kgPO4-eq. The potential for ozone depletion, biofiltration contributes significantly to 3.09x10-12 kgCFC-11-eq. Conclusion, significance and impact study: Based on the comparison of technology, it is known that Tripikon S has the potential for environmental impact is quite minimal and can be an option to be applied to the river banks.]]>

<![CDATA[Domestic wastewater generated from various types of buildings has been recognized to be different to some extent. This research aimed to know the quality, quantity, fluctuation of quality, and fluctuation of quantity of domestic wastewater discharged from office buildings. The composite samples were taken from two office buildings. The black water and gray water were taken from Building A with number of people 53 persons, and the mixed wastewater was taken both from Building A and Building B with number of people 900 persons. The fluctuation and quantity of wastewater were measured every hour from 7 am until 4 pm during the working time. The results showed that the quality of wastewater from office building contained 176 to 238 mg/L COD, 73.06 to 106.51 mg/L TN, and 3.66 to 7.70 mg/L TP with the average of C:N:P ratio was 100:42:2.56. Quantity of wastewater discharged from office buildings were from 39.61 to 49.93 liter/person/day. COD concentration changed significantly during the working time with mean ± standard (252.5±89). The quantity of wastewater varied over time and the peak discharge for black water and gray water were 2.85 litter/person/hour and 3.74 liter/person/hour, which occurred during the beginning of working time and the praying time of muslim Indonesian culture. It suggests that the domestic wastewater from office buildings has specific characteristics and it contains high concentration of nutrient that is required appropriate advanced technology for treating this kind of wastewater.]]>
