<![CDATA[Water is a very important component for human life. The increasing number of people in Indonesia, such as in the city of Bekasi, will directly result in the demand for clean water for human daily needs getting higher. Quality of water to meet human needs must also be considered. In this case, the Bekasi government through PDAM Patriot Bekasi plays a role in fulfilling water for the needs of its people. However, water from PDAM is only used for clean water needs and cannot be consumed for drinking water. Therefore, this research will provide an alternative so that water is not only used for clean water but also can be used for drinking water by considering existing health standards referring to the Minister of Health Regulation No. 492/MENKES/PER/IV/2010 about drinking water and Minister of Health Regulation No. 416/MENKES/PER/IX/1990 about clean water. The research was carried out by filtration through two (2) samples for testing. The results showed that the use of sand in the filtration method was able to improve quality of PDAM water, both water clarity and color according to regulations as drinking water standards with an arrangement of using medium gravel, coarse sand, red brick, limestone, and fine sand.]]>

<![CDATA[Sunter C river is located on Yos Sudarso street at coordinates 6°8'32,63" South Latitude, 106°53'25,78" East Longitude and downstream Sunter C river is located on Sunter Barat river street coordinates 6°8'24,78" South Latitude, 106°51'24.68" East Longitude. In area around the Sunter C river, there are still frequent floods every time the rainy season arrives because of the narrowing of canal section in upstream area of Sunter C river and Sunter C river water can’t flow gravitationally to Sentiong river because the base elevation of Sentiong river is higher than Sunter C river. From the above conditions, it’s necessary to analyze the problem of flooding in Sunter C river area to find out whether Sunter C river can still accommodate water discharge based on rainfall in the last 10 years and does the Sunter C river need normalization. Based on the results of manual calculations and HEC-RAS application, the Sunter C river can’t accommodate water discharge based on rainfall for the last 10 years of 15.88 m3/s. At point 0 - point 3 it is necessary to normalize by widening the cross-section from 3.6 m to 8 m and at point 4 from 4.8 m to 8 m.]]>

<![CDATA[The main objective of the research work is to present the buckling analysis of plates subjected to uniform compressive load. To obtain accurate results in analysis plate must be free from shear locking, this phenomenon occurs when the ratio of length to thickness ratios plate increases. Many investigations have been carried out on plate elements to see the behavior of a plate in the case of thin plates. In this paper, we investigated plate analysis in the case of buckling analysis using one of the finite element plates, the numerical analysis was conducted on a skew plate with varying length to thickness ratios, and skew angles. The reference solution in the literature will be used to compare the analysis results the level of convergence and plate performance will be obtained.]]>

<![CDATA[Surface settlement of flexible pavement in coastal reason occurs for the movement of heavy vehicle, liquefaction of soil layer during seismic shaking, land sliding etc. In coastal area, surface settlement is higher than other geographical area because several sandy layers present in the coastal reason. Surface settlement disturbs the longevity of flexible pavement in homogeneous sandy layer. Waste coconut fiber (WCF), fly ash, coir etc. are suitable additives for reducing such types of settlement. In the present study, numerical analysis performs PLAXIS 3D and various (5, 10, 15, 20, 25) percentages of WCF mix with the asphalt by weight for reducing surface settlement of flexible pavement. Mohr-Coulomb failure criterion uses in the numerical analysis and liquefaction has not considered in the present study. However, WCF increases elastic modulus of flexible pavement and it reduces settlement of the pavement. Minimum surface settlement occurs at the maximum percentage of WCF and it is 1.68mm. Therefore, mixer of WCF protects the flexible pavement against severe damage.]]>

<![CDATA[Design changes are inevitable in most projects. In many construction projects they may look not too complicated to be executed in front of computer models. The actual situation turned out to be the other way around. Apart from detailed changes in shop drawings, bill of quantity and specifications, administrative works related to the project are quite considerations. These mounted consequences would be more for short duration projects with government funding executed in the near end book period. The allocated execution period for short duration projects is not usually allowing rapid changes for the unexpected consequences. This paper presents what actually happens inside the project management during the contract change order process.]]>

<![CDATA[LRT (Light Rail Transit) is one solution for an environmentally friendly transportation system to overcome congestion problems that occur in Jakarta. This mass transportation is considered effective because there is less land in the capital for road construction. The project is a complex project that includes design, material procurement and construction. The development that is currently underway is cross-service 1 (Cawang-Cibubur), cross-service 2 (Cawang-Dukuh Atas) and cross-service 3 (Cawang-Bekasi East). This study aims to determine the risks that often arise and find out the right way to handle the risks that arise in the construction of the JABODEBEK LRT project. Data was collected using a questionnaire on 45 respondents who were involved in the construction of the JABODEBEK LRT project. The variables studied in this study are aspects of scheduling planning, aspects of scope and work documents (contracts), aspects of organizational systems, coordination and communication, aspects of resource readiness/preparation, aspects of inspection systems, work control and evaluation and other aspects (force majeure /beyond the ability of the owner and contractor). Data processing in this study used the SPSS version 25 program. This study discusses seven variables classified as high risk (H) in the project.]]>

<![CDATA[Explosions in buildings are not always the result of terrorist attacks, but can also be caused by several work accidents due to explosive tools or materials as trigger of problems in construction. Friedlander's equation has many modifications including the Reed equation. Reed proposes a modification of Friedlander equation using 4th order polynomial. The Reed equation is still not close relatively to the Friedlander equation. The Reed equation is only calculated up to t = 25/7 (s) in the negative phase. Meanwhile, the Friedlander is calculated at t = 5 if both are reviewed at no load or one unit condition. It is necessary to evaluate using the 4th order polynomial equation which is close to the Friedlander explosion equation. Dynamic behavior of structures must be considered in the design of structural elements. The purpose of this study is to analyze numerically the effect of explosions on orthotropic slabs which have partial fixity placement and stiffeners in the x direction, namely in the short span direction. The behavior of the plate orthotropic configuration, the localized blast load are centered in the middle of the strain, and the effect of thickness and stiffening on the vertical deflection of the plates are solved numerically using two auxiliary equations in the x and y-directions. From the analysis, it is found that there is vertical deflection with related to time. This paper introduces the dynamic behavior of Reed's modified blast loads with 4th order polynomial on orthotropic plates with x-direction stiffener beam.]]>

<![CDATA[The flare stack serves to protect process equipment facilities against unexpected overpressure. This study aims to follow up on previous research that recommends improvements to the flare stack structure based on corrosion findings that occur in the area of the riser stack around the ring connection for the guy wire. By replacing rusty material, it is also necessary to consider modifications to prevent the risk of re-corrosion. Based on current design observations in the connection ring area for guy wire, side cutting is required which can result in water being trapped. This research aims to find out whether by modifying the connection ring for guy wire, this flare structure still has structural reliability when receiving critical outer loads or not. Based on the results of the study, it shows that modifying the geometry of the connection ring guy wire still provides reliable structural performance when receiving critical outer loads. The maximum stress that occurs in the area around the pad eye is 71.2 Mpa with a maximum stress ratio of 0.434 it shows that the value is still quite far from the maximum allowable voltage ratio of 1.0. So it can be concluded by modifying the connection ring for guy wire to prevent the risk of corrosion can be done without causing a decrease in the performance of the structure in withstanding critical outer loads.]]>
