Abstract

Abstract. Waste is an environmental problem that is the concern of everyone, increasing the volume of waste every year produced from the source. President University is one of the source that is still use the old paradigm in waste management makes President University continues to be one source that can increase the volume of waste that will be disposed of to landfill. This is reinforced by the increasing number of students each year. Therefore, as a role model from education level, proper waste management is needed. Objectives: Based on that, the objective of this research is to describe the existing condition of waste management at President University and to measure the waste generation and waste composition as baseline data for amount of dustbin and temporary waste collection area needed. Method and results: The Method implemented in this research using SNI 19-3964-1994 standard. The result showed that the total of waste generation at President University reached 238 gr/day/person with a total of 14% compostable waste, 31% recyclable waste, and 55% residue. Conclusion: It was suggested to plan and operate dustbin that following its types with the color-coded for different types of waste generation in President University. Also, recommend some alternative treatment ideas such as composting or anaerobic digester for treatment the waste.

Abstract

Abstract. Water used to meet the daily needs of human has different characteristics depending on the quality and amount of substances found in it. Turbidity can performance the quality of the water. The raw water used in this research comes from Kalimalang River. Coagulation and flocculation are one of the most important processes to remove the substances in raw water. Detention time is the main parameter for the flocculation process. Objectives. This research aims to find out the optimum of detention time in the flocculation prototype unit. Methods and result. Designing and assembling the flocculator lab-scale prototype using 20 cm of pipe diameter. Running the prototype and analysis the effect of detention time to the clarified water turbidity in 30 minutes of 1 Liter imhoff cone with raw water range 41-60 NTU in a long dry season. The result is the optimum clarified water turbidity is found in the 19,7 minutes detention time appropriate to the 41-60 NTU raw water turbidity range. Conclusion. The result shows, that the optimum detention time was obtained in 19,7 minutes for 41-60 NTU raw water turbidity range.

Abstract

Kampung Babakan Cikeruh is a slope or ridge area , a few years ago this area did not experience any difficulty in water availability because the land had not yet changed its function, Since the development of the land conversion function as a housing area, it has caused a decrease in the ground water level in the dry season, so that it becomes a problem for residents because residents rely on wells to be a source of water for household needs every day. Based on these conditions, it is necessary to have groundwater conservation measures at the study site, so that groundwater level subsidence is not deep. The research methodology used to identify the problem, then determine the scope of the problem, conduct a literature review that is relevant to the problem under study, so that the formulation of the theoretical framework, hypotheses and conceptual concepts of the solution to the problem being examined, then make the method of conducting research including determining the location, gathering data and analysis, so as to produce solutions to the problems studied and researchers will provide conclusions. The researcher provides a solution in the form of leach absorption wells, and from 10 wells examined, the researcher makes infiltration wells that are between 3 adjacent wells and the results obtained 3 wells have a stable ground water level in the dry season. the conclusion is the effort to conserve water to maintain the stability of the ground water level in the dry season by making infiltration wells.

Abstract

Due to the data in 2030, the urban growth in developed countries is 83% and developing countries is 53%. Jababeka II Industrial Estate as one of the urban industrialization located at Bekasi Regency. In its development, drainage facilities are one thing that must be considered. Because with its function as a channel that carries runoff water to rivers/lakes/reservoirs to avoid flooding. This study aimed to know the existing condition of the drainage system and the water balances in the form of runoff in Jababeka II Industrial Estate by the simulation of SWMM 5.1.  The method of this research used a quantitative method, and the data collection method used secondary data, including the information from the existing drainage system with precipitation events in 12 years (2009-2020) were obtained from the WTP Jababeka Residential, drainage dimension, and masterplan of Jababeka II. In order to calculate rainfall planned used fifth-year return period based, it’s on the city's classification under study. The probability distribution method uses Log-Pearson III with a planned rainfall of 128.22 mm/d and the highest rainfall intensity of 54 mm. Based on the simulation results, it was found that the Jababeka II Industrial Estate contained puddles in several channels. The peak was at the 3rd hour of the simulation, which were 19 channels. It's influenced by the type of soil that is quickly saturated. The simulation of the existing condition at Jababeka II has the highest runoff at the 2nd hour of simulation, and floods occurred in 19 channels. It’s affected by the impermeable sub-areas. The water balance result is the amount of precipitation 128.22 mm with the intensity is 54mm due to 5 years forecasting, thus producing the outflow is 128.511 mm. Therefore the number of continuity errors of the surface is -0.227%.

Abstract

Abstract. PT HS is a world’s leading toy manufacturing company with more than 6,000 workers. Due to the high number of workers in PT. HS, it will impact to domestic activities (toilet discharge). Based on the annual report for wastewater effluent, noted that parameter ammonia from PT HS’s wastewater effluent was exceeding the industrial estate limit which the average of ammonia concentration is 50 mg/L. Whereas, In the industrial estate regulation contain of several standard parameters that must be comply by the company such as ammonia standard which has maximum 10 mg/L for the wastewater effluent. Objectives: The objectives of this experiment are to know the optimum dose of NaOCl 9% on ammonia removal and to know the concentration of residual chlorine after the treatment process. Method and results: This research use the experimental method to get the primary data. After the experiment in the laboratory, the results proved that the sodium hypochlorite exposure reduces ammonia concentration in water samples with 82,2% removal efficiency from 50 mg/L to 8,9 mg/L ammonia concentration reduced with 110 mg/L of NaOCl 9% solution within 30 minutes contact time and it resulted the residual chlorine 0.72 mg/L. Conclusion: The chlorination process was effective to reduce the ammonia concentration. Also, the residual chlorine was still in the standard limit which not exceeds from 1 mg/L. The result also shows that the dose variations of sodium hypochlorite influence ammonia removal efficiencies. Also, mostly the total residual chlorine forecast will increase with the increasing sodium chlorine dose.
