The need for clean water quality has increased every year, especially in big cities in Indonesia. This is triggered by the high population growth which causes the need for clean water to be urgently needed. Lack of water catchment areas and green land exacerbates the amount of clean water. In addition, the cause of the decline in clean water quality is also influenced by the many negative activities carried out by humans, one of which is the activity of disposing of garbage in the river, reservoir / setu and drainage areas. The use of chemicals, namely Poly Aluminum Cholrid (PACPOWDER) in the processing of river water or river water requires high operational costs, which results in high costs for people who subscribe to PDAM. The filtering pattern of water can be done by referring to the soil layer in the form of an aquifer, so that the water that is not good can be filtered in the presence of an aquifer and can purify the water into drinking water. The use of artificial aquifers that have currently been carried out by the Ministry of Public Works is through rain, where through the filtration of rainwater containing acidic levels it can be neutralized through artificial aquifers into clean water and can be applied to areas of high drought levels.
对清洁水质的需求每年都在增加,尤其是在印度尼西亚的大城市。这是由人口的高速增长引发的,这导致人们迫切需要清洁的水。集水区和绿地的缺乏加剧了清洁水的数量。此外,清洁水质下降的原因还受到人类进行的许多负面活动的影响,其中之一是在河流,水库/水库和流域地区处理垃圾的活动。在河水或河水的处理过程中使用化学品,即聚铝胆碱(PACPOWDER)需要很高的运营成本,这导致订阅PDAM的人的成本很高。水的过滤模式可以参照含水层形式的土壤层来完成,这样不好的水可以在含水层存在的情况下进行过滤,可以将水净化成饮用水。公共工程部目前使用的人工含水层是雨水,通过过滤含有酸性的雨水,可以通过人工含水层将其中和为清洁水,并可应用于高度干旱的地区。

NUMERICALLY PREDICTING SETTLEMENTS OF WASTE COCONUT FIBER (WCF) MIXED FLEXIBLE PAVEMENT IN HOMOGENEOUS SANDY SOIL BY USING PLAXIS 3D 利用plaxis 3d对均质沙土中废椰子纤维混合柔性路面沉降进行数值预测

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.
沿海地区柔性路面的地表沉降主要是由于重型车辆的移动、地震震动时土层的液化、地面滑动等原因造成的。沿海地区由于多砂层的存在,地表沉降比其他地理区域要大。均质砂层中路面沉降对柔性路面寿命的影响。废椰子纤维(WCF)、粉煤灰、椰胶等是减少此类沉降的合适添加剂。在本研究中,数值分析了PLAXIS 3D和不同(5、10、15、20、25)WCF混合料与沥青的重量百分比,以减少柔性路面的表面沉降。数值分析中采用莫尔-库仑破坏准则,未考虑液化问题。而水cf增加了柔性路面的弹性模量,减少了路面的沉降。地表沉降最小值出现在WCF比例最大时,为1.68mm。因此,WCF混合器保护柔性路面免受严重破坏。

Pub Date : 2021-04-02 DOI: 10.24853/ijcei.1.1.23-32

Adhyaksa reservoir is located within the Adhyaksa Public Hospital on Mabes Hankam street number 60, Ceger, Cipayung district, in the area of East Jakarta, which is one of the areas prone to flooding. Adhyaksa reservoir has a pump house available that is used to pump the excess water in the reservoir but there are still puddles in several places around the residential area. The problems occurs due to sedimentation in the canal, inadequate size of the canal, and narrowing of the canal. These causes the canal that is supposed to drain water into a reservoir to not work optimally. By conducting canal analysis using Log Pearson III method, using data obtained from 3 Rainfall Station namely, Bekasi Rainfall Station, Halim Rainfall Station, and Bogor Rainfall Station, it was found that the rainfall intensity that occured in the last 10 years cycle is 162,29 mm. Then, the Mononobe equation was used to find the intensity of rain per hour that occours. The planned rain discharge was then found using a rational method. From these calculations, it was discovered that there are 9 canals namely (5, 11, 12, 13, 17, 18, 19, 20 and 23) that are unable to accommodate the rainfall that occurs.
Adhyaksa水库位于东雅加达地区易发生洪水的地区之一的Cipayung区Ceger Mabes Hankam街60号的Adhyaksa公立医院内。Adhyaksa水库有一个抽水房,用来抽水水库中多余的水,但在居民区周围的几个地方仍然有水坑。这些问题的发生是由于运河的沉积,运河的大小不足,以及运河的变窄。这导致本应将水排入水库的运河无法发挥最佳作用。利用别加泗、哈利姆和茂物3个雨量站的数据,采用Log Pearson III方法进行渠道分析,发现近10年周期发生的降雨强度为162,29 mm。然后,Mononobe方程被用来计算每小时发生的降雨强度。然后用合理的方法找到计划的降雨量。从这些计算中,我们发现有9条运河(5、11、12、13、17、18、19、20和23)无法容纳发生的降雨。

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.
建筑物的爆炸并不总是恐怖袭击的结果,也可能是由于爆炸工具或材料引发的施工问题而引起的几次工作事故。弗里德兰德方程有很多修改,包括里德方程。Reed用四阶多项式提出了对Friedlander方程的修正。里德方程与弗里德兰德方程仍然不太接近。Reed方程只在负相计算到t = 25/7 (s)为止。同时,如果两者在空载或一机组条件下进行评审,则弗里德兰德在t = 5时计算。有必要用接近弗里德兰德爆炸方程的四阶多项式方程进行计算。结构单元的设计必须考虑结构的动力性能。本研究的目的是数值分析爆炸对x方向(即短跨方向)具有部分固结布置和加筋的正交各向异性板的影响。采用两个辅助方程在x和y方向上数值求解了板的正交各向异性、局部爆炸荷载集中在应变中间的特性,以及厚度和加筋对板垂直挠度的影响。从分析中发现,存在与时间有关的竖向挠度。本文介绍了四阶多项式里德修正爆炸荷载在x向加劲梁正交各向异性板上的动力特性。

CANAL CAPACITY IN AREA SUMUR BATU PUMP HOUSE – CENTRAL JAKARTA 雅加达中部sumur batu泵房地区的运河容量
Pub Date : 2021-04-02 DOI: 10.24853/ijcei.1.1.33-45
Tanjung Rahayu Raswitaningrum, B. K. Wardana
Sumur Batu Pump House is located at Inpeksi Kali Sunter street, Sumur Batu Village, Kemayoran District – Central Jakarta, with coordinates 6°9'41.29" south latitude and 106°52'25.02" east longitude. In the southern part of Sumur Batu Pump House, there is Kodam Complex where there‘s a main canal that flows to the Stone Well Pump House. Around the area of Sumur Batu Pump House, especially Kodam Complex,  flooding still happens frequently, especially during the rainy season. One of the factors causing the flooding is that many canals are sedimented and the dimension of the canals are insufficient to discharge existing rainfall, as well as insufficient pump capacity. By analyzing the canal using Pearson III Log distribution method and Normal Log, and by predicting the highest planned rainfall score in the next 5 years period, which was calculated using past 25 years of rainfall data obtained from Tanjung Priok Rainfall Station, Kemayoran Rainfall Station, and Halim Rainfall Station, which was then calculated by Thiessen method, it was discovered that the rainfall intensity that occurred for a period of 5 years is 167.01 mm in the Normal Log distribution method. The mononobe equation is then used to find the intensity of rain per hour that occurs. Finally, the rain discharge plan can be sought by using rational method. It is then discovered that there are 4 canals (Canals E, H, I, J) that can’t accommodate the occurring rain discharge.
Sumur Batu泵房位于雅加达中部Kemayoran区Sumur Batu村Inpeksi Kali Sunter街,坐标为南纬6°9′41.29”,东经106°52′25.02”。在Sumur Batu泵房的南部,有一个Kodam综合体,那里有一条主要的运河流向石井泵房。在Sumur Batu泵房周围,特别是Kodam综合设施,洪水仍然经常发生,特别是在雨季。造成洪涝的因素之一是河道淤积较多,河道尺寸不足以排出现有的降雨,以及抽水能力不足。利用Tanjung Priok雨量站、Kemayoran雨量站和Halim雨量站近25年的降水资料,利用Thiessen法预测了未来5年的最高计划雨量,并采用Pearson III Log分布法和正态对数法对运河进行了分析。根据正态对数分布方法,发现5年的降水强度为167.01 mm。然后用单值方程计算每小时的降雨强度。最后,运用合理的方法,寻求出排雨方案。然后发现有4条运河(运河E, H, I, J)不能容纳正在发生的雨水排放。

It is then discovered that there are 4 canals (Canals E, H, I, J) that can’t accommodate the occurring rain discharge.","PeriodicalId":389729,"journal":{"name":"International Journal of Civil Engineering and Infrastructure","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114286249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CAPACITY OF SUNTER C RIVER IN NORTH JAKARTA 雅加达北部sunterc河的容量
Pub Date : 2021-04-02 DOI: 10.24853/ijcei.1.1.1-13
M. Imamuddin, Muhammad Lutfi Fadilah
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.
Sunter C河位于Yos Sudarso街,坐标为南纬6°8′32,63”,东经106°53′25,78”,下游Sunter C河位于Sunter Barat河街,坐标为南纬6°8′24,78”,东经106°51′24.68”。在森特C河周边地区,由于森特C河上游地区渠段变窄,每逢雨季洪水仍然频繁,森特C河的水由于森特C河的底面高程高于森特C河,无法通过引力流向森特C河。在以上条件下,有必要对Sunter C河区域的洪水问题进行分析,以确定Sunter C河是否仍然可以根据近10年的降雨量进行放水,是否需要正常化。人工计算结果和HEC-RAS应用表明,近10年的降雨量为15.88 m3/s,孙特尔C河无法容纳排水量。在0点- 3点,需要通过将横截面从3.6米加宽到8米进行归一化,在4点从4.8米加宽到8米。

CANAL CAPACITY IN AREA IKIP AND PULOMAS 管道容量在区域ikip和肺泡
Pub Date : 2021-04-02 DOI: 10.24853/ijcei.1.1.46-54
Budi Satiawan, Puspita Maratus Sholeha
IKIP’s Pump House is located on Inspeksi Kali Sunter street, North Jakarta, geographically located between 6°9'45.55" South Latitude and 106°52'53.8” East Longitude. While Pulomas’s Pump House is located on Perintis Kemerdekaan street North Jakarta, geographically located between 6 °10'0.71'' latitude and 106°52'51.66” east longitude. On the arterial road beside Ria-rio Reservoir to Kayu Putih street, floods often occur during the rainy season. That flood is caused by several factors, one of which is the drainage canal that can’t function properly. At several points of water canal that will lead to Pulomas’s Pump House there’s a lot of plastic waste and people's belongings that cause narrowing of canal. The high sedimentation in the form of mud also causes water capacity that can be accommodated by canal is not optimal. From the above conditions, it is necessary to do an analysis pump capacity to determine whether IKIP’s Pump House and Pulomas’s Pump House can still accommodate water discharge based on 15 years of rainfall lastly, and it is known that there are three canals in the Pulomas pump house that cannot accommodate the water discharge so that flooding occurs
iip泵房位于雅加达北部Inspeksi Kali Sunter街,地理位置位于南纬6°9′45.55”和东经106°52′53.8”之间。Pulomas的泵房位于雅加达北部的Perintis Kemerdekaan街,地理位置位于东经6°10'0.71”和东经106°52'51.66”之间。在Ria-rio水库旁通往Kayu Putih街的主干道上,雨季经常发生洪水。洪水是由几个因素引起的,其中一个是排水渠不能正常运行。在通往普拉马斯泵房的水渠的几个地方,有很多塑料垃圾和人们的物品,导致水渠变窄。淤泥形式的高沉降也导致运河可容纳的水量不是最佳的。综上所述,有必要对水泵容量进行分析,最后根据15年的降雨量来确定iip泵房和Pulomas泵房是否还能容纳放水,并且已知Pulomas泵房有三条渠道无法容纳放水,从而发生洪水
