Abstract

Demak is a growing regency which is located in Central Java Province. The growth is mainly in the industrial sector and population settlement. Demak Waterwork Company has served 21.178 customers with the capacity flow of 159.33 l/s which is predicted to reach 300 l/s or double in the next 10 years in 2027. The Water Distribution Networks (WDN) was developed in a large zonation that resulted in the flow of water not being properly managed. The lack of water supply due to low the pressure especially at peak hours, the level of leakage, and the difficulty to detect leakage are potential to be a serious problem that should be solved. The objectives of this study include projecting of demand for drinking water in the 2036 and designing a  zoning system to meet future needs of drinking water.  This study applied epanet modelling to simulate the water network system in existing and predicted condition. The result showed that in selecting the pipe for replacement, some aspects to be considered including the characteristics of pipes, pipe materials and pipe size based on the load of drinking water to be carried. Some developmental strategies e.g improving the capacity, establishing zones, and resizing the pump capacity will improve the reliability and efficiency of the water distribution network. The pressure model resulted in enough value to supply the whole area of more than 0.5 bar in service pipe.

Abstract

Water treatment in Indonesia still uses coagulant to reduce the contaminant. Therefore, an infiltration gallery is required as the pre-treatment before conventional water treatment conducted. Infiltration gallery is a natural technology for absorbing or filtrating the contaminant. The hydraulic conductivity plays the main role in soil filtration. There are many types of soil with different hydraulic conductivities. In infiltration gallery method it is important to identify the hydraulic conductivity value as the preliminary analysis because it is the important indicator to show the ability of soil to flow the water from one side to other sides when filtrating the contaminant. The slower the conductivity is, the better the quality of the water will be. The method used in this study was the Constant head Permeameter. The result of this study shows that the same type of soil type has different hydraulic conductivities.

Abstract

The ability to respond and recover from disasters is highly dependent on the community’s capacity. This study assessed the community’s capacity level in Kasembon District, an area that was impacted by the Mount Kelud eruption in 2014. Capacity level assessment is done by identifying pentagon asset components, covering human capital, social capital, financial capital, natural capital and physical capital. Bayem is a village with the medium capacity in spite of the low ownership of natural capital, financial capital and physical capital as it has been supported by the active participation of the community within the village organization. Pondok Agung, Kasembon, Sukosari and Pait are four villages which are almost the same with Bayem, but the involvement of the community is not as active as in Bayem. Based on the results of the research, villages that are socially active, tend to have a higher capacity.

Abstract

A product will enter the end of life phase when the usage period expires. End of life recycleis divided into three categories, namely reuse, recycle, and landfills. Reuse is transferring usage rights to others to be used for the same purpose. Recycle is utilising used goods as raw materials for other products. Landfills are putting used clothing to a garbage dump site. Consumers have different tendencies to the expired product. Stamped batik as a typical product of Solo also experiences the same treatment at the end of its life. This study has the objective of reviewing the consumer behaviour toward the stamp batik and calculating the energy needed in the final product period. Simapro 3.8.0.0 sofwate was used for the analysis. Based on consumer behaviour toward the end of product life, the stamped batik user mostly transfer the function of stamped batik to cleaning cloth or recycle (48.97%). The energy needed for the recycling process of stamped batik is 3.2 kPt. The energy resources of the landfill of stamped batik are 0,085 kPt. The electrical energy used for landfills of stamped batik is  14.4 MJ per year.

Abstract

The area of the campus of Institut Teknologi Sepuluh Nopember (ITS) and its housing complex are usually inundated during heavy rain. It is because the slope of the land in the campus generally flat. Moreover, it is because some of the drainage channels contain sediment that reduce the optimum capacity of the channels. Hence, an evaluation of the drainage system of ITS needs to be conducted.  The steps of doing this evaluation are (i) identification of the existing problems, (ii) collection of primary and secondary data, (iii)  literature review, (iv) calculation of capacity of the existing channels, (v) calculation of runoff, and (vi) analysis of the existing retention ponds. The primary data includes flow direction, the slope of channels, dimension of channels, and thickness of sediment in the channels. The secondary data comprises of rainfall intensity, Master Plan of ITS, and land-use. The calculation includes engineering design, bill of quantity (BOQ), and budget. A standard operation procedure for maintenance of drainage system to make the channels optimum is also suggested. From the analysis, it is shown that the maximum daily rainfalls are 136.09 mm/day for 5 year-rainfall return period and 159.19 mm/day for 10 year-rainfall return period. The cause of inundation in ITS is there are some channels which are not connected to each other. As a result, the drainage water cannot flow easily to receiving water body (river). Another cause of inundation is the slope of some channels that does not properly made. The inundation of some roads is because there are no street inlets such that the water could not flow to the side channels. It can be concluded that (i) it needs some addition of secondary channels and box culvert in some areas, (ii) the slope of some channels need to be rearranged, (iii) 288 street inlets must be constructed along the planning area.

Abstract

Kamoning River watershed is one of the watersheds in Sampang. Sampang City experienced flooding almost every year caused by the overflow of the River Kamoning. One of the causes of flooding in that city is the high rainfall and a lack of rainwater catchment areas in the upper and middle Kamoning River watershed. To overcome these problems, it is necessary to use a system of flood discharge reduction ecodrainage in the upstream and in the middle of Kamoning River watershed. This study used two scenarios of ecodrainage system: first is to change the land use in combination with the creation of retention ponds, the second scenario is to change the land use in combination with the creation of infiltration wells. From the analysis of large unknown, designed-flood discharge of 50 year-return period of Kamoning River basin is 289.361 m3/ sec. By using the first scenario, the designed-flood discharge can be reduced by 199.59 m3/s or 31.02%, while large designed-flood discharge can be reduced by 205.20 m3/s or 29.08% using second scenario. Efforts to reduce the discharge flood in Sampang can be effectively done by using the scenario 1.

Abstract

Karangpilang II Water Treatment Plant (WTP) is a part of Karangpilang WTP of Surabaya City Water Company, (PDAM Surya Sembada), that serves the water supply for Surabaya City. Karangpilang II WTP has the biggest clean water production capacity in Karangpilang WTP, which is 2500 L/s. Using conventional treatment to remove turbidity, the treatment plant in Karangpilang II WTP consists of pre-sedimentation unit, clearator unit and filter unit. In this study, evaluation of turbidity quality in production water and turbidity removal efficiency  were conducted to analyze the Karangpilang II WTP performance in turbidity treatment. The evaluation is conducted using 2016 data, by  comparing the turbidity of production water with the Water Quality Standard of PDAM, and by comparing the turbidity of raw water, each treatment units effluents and production water. The evaluation result shows that in the case of Karangpilang II WTP turbidity removal performance, there were some occurrences that the turbidity in production water still not fulfilled the standard quality. The evaluation result also shows that there was a unit in the Karang Pilang II WTP with inadequate performance in turbidity removal, which was the pre‑sedimentation unit. The solution that may be given to solve the problem of turbidity removal in Karangpilang II WTP are: increase the maintenance schedule for pre-sedimentation unit; determine the proper turbidity reference in determination of coagulant dose; optimize the coagulant dose; using produced sludge from water treatment as coagulant aid along with Al2SO4; and using capping material in filter unit.

Abstract

One of the environmental issues that can affect human health is air pollution. As the second largest city in Indonesia, economic development and infrastructure construction in the city of Surabaya led to the increasing role of industrial and motor vehicle use which is proportional to the increase in fuel oil consumption. This condition ultimately led to declining air quality. Gas pollutants that contribute to air pollution such as CO, SO2, O3, NO2 and particulate matter PM10 are pollutants that have a direct impact on health. This study aims to analyze, monitor and predict air pollutant concentrations recorded by the Environment Agency Surabaya City based on time series with Fuzzy Time Series.MAPE calculation results on the parameters of pollutants are NO2: 23.6%, CO: 19.5%, O3: 22.75%, PM10: 9.96% and SO2: 3.6%.

Abstract

The whole planning of urban infrastructure development should refer to the Urban Spatial Detail Plan (RDTR) that has been developed by the Regional Government. One of them is drainage system planning which also need to pay attention to land use change plan which have take effect on increasing of coefficient value of run-off which is the result of increasing number of land cover. Based on the land use-planning spatial structure patterns in 2034, there is an increase in land cover a total area of 75 hectares. Therefore, it is necessary to evaluate the urban drainage system in order to avoid problems in future. Calculation of flood discharge using the rational formula with the value of the coefficient value of run-of on spatial structure plan. The analysis of existing drainage system is carried out to find out whether still capable of accommodating the discharge in spatial structure plan in 2034. Based on the drainage channel capacity analysis, 30 channels have to be repaired.The handling is done by widening the channel and increase the number of channels along the 3191.36 m. Another effort to reduce the flood is by making absorption wells in residential areas with the total amount needed as many as 179 units.
