Often we encounter several obstacles that cause traffic concentration at several points on a road segment which causes traffic movement to slow down and even stop. Concentration of traffic flow occurs at intersection points, such as one at the Pilau-Keruing intersection, where traffic moving on the Pilau road is forced to slow down when the traffic flow from Keruing road turns right to cut the flow. Therefore, it is very important to know the effect of turning movement on the smooth flow of traffic. Data collection was carried out by sending several surveyors to the field to obtain secondary and primary data. Furthermore, the analysis of road performance using the 1997 Indonesian Road Capacity Manual. The average space speed obtained from the graph of the relationship between DS and vlv is vlv=28 km/hour. The average speed from the results of the speed survey on the road section gives a value of vlv = 29.6 km / h with conditions without any obstacles to the flow of turning from the Keruing road to the Pilau road, and vlv = 25.6 km / h with the presence of turning current obstacles . There was a decrease in average travel time of 5.9 seconds, with a decrease in traffic speed of 4 km/hour due to the influence of vehicles turning from Keruing road to Jati road.
我们经常会遇到一些障碍物，这些障碍物会在路段的几个点上引起交通集中，从而导致交通运动减慢甚至停止。交通流集中发生在十字路口，如皮劳-科鲁路口，当科鲁路的车流右转以切断流量时，皮劳路上的车辆被迫减速。因此，了解转弯运动对交通畅通的影响是非常重要的。数据收集是通过派遣几名测量员到现场获取次要和原始数据来进行的。此外，使用1997年印度尼西亚道路容量手册对道路性能进行了分析。由DS与vlv关系图得到的平均空间速度为vlv=28 km/h。从路段速度调查结果中得出的平均速度，在从科鲁路到皮劳路的转弯流没有任何障碍的情况下，vlv = 29.6 km / h，在存在转弯电流障碍的情况下，vlv = 25.6 km / h。平均出行时间减少5.9秒，交通速度下降4公里/小时，受车辆从科令路转向贾提路的影响。

Stagnant water in the highway area is the cause of disruption of the smooth flow of vehicle traffic. Even the overflowing of air from the road creates a large flood supply in the road area. The problem of flooding in the Ijen Bondowoso crater road area was also triggered by the inability of the channel that functions to fill the flood water discharge that occurs in this road area. From this problem, it is necessary to study regarding the adequacy of the capacity of the road channel on roads with a fairly high slope such as what happened in the area of Ijen Crater road, Bondowoso From the results of this study it can be seen that the average daily rainfall is the result of 100,461 mm and the relative average rainfall intensity of each channel for the 10 year return period is 63,301 mm / hour. The flood discharge plan is calculated from 2 to 100 years. In this drainage design analysis, the design flood discharge is calculated for only 10 years, and a planned flood discharge is obtained of 0.423 m3 / second. The channel required to fill the flood discharge is a rectangular channel with the size B = H = 0.6 m. It is recommended to always carry out a comprehensive study with regard to changes in the road body of the road along with the increase in existing traffic. As well as the infrastructure of the existing channel and feeding the community around the road, it will be clean and not littering, especially in the road channel
高速公路区域的积水是扰乱车辆通行的原因。甚至从道路上溢出的空气也会在道路区域产生大量的洪水供应。Ijen Bondowoso火山口道路地区的洪水问题也是由于无法填补该道路地区的洪水排放而引发的。从这个问题来看，有必要研究道路通道在像Ijen Crater road, Bondowoso这样坡度较大的道路上的通行能力是否足够。从本研究的结果可以看出，平均日降雨量为100,461 mm，各通道10年回归期的相对平均降雨强度为63,301 mm / h。泄洪计划按2 ~ 100年计算。在本次排水设计分析中，设计洪流量仅计算10年，得到的规划洪流量为0.423 m3 / s。填洪通道为矩形通道，尺寸为B = H = 0.6 m。建议始终对道路的道路体随着现有交通量的增加而发生的变化进行全面研究。以及现有的基础设施渠道和喂养社区周围的道路，它将是干净的，不乱扔垃圾，特别是在道路渠道

The intake building for Embung Sei Bubu had been designed to be an open channel with the flood gate. The flood gate had been designed from steel with a net width of 1.35 m and the height of the door opening is 0.0076 m. The corrosion is one of the hazardous threat to the strengthness and durability of the flood gate. This research numerically models flood gate that was attacked by pitting corrosion. The pitting corrosion had been modelled in several small holes randomly were distributed on the surface of the flood gate, precisely on the surface of the water. The numerical modeling had been performed in finite element method utilized computer programs such Abaqus. The results showed there was a reduction in the capacity of the steel flood gate due the hole increasing. The reduction in stress capacity had been indicated by the stress concentration that was occured around the pitting corrosion. The stress reduction occured with the change in the percentage of pitting corrosion distribution area of 10% (225 MPa), 20% (175 MPa) and 30% (120 MPa)

The main basic ingredients needed for the manufacture of this geopolymer material are materials that contain a lot of silica and aluminia elements. The 1st stage test was carried out to determine the geopolymer paste with the maximum compressive strength at the ratio of NaOH to Na2SiO3 of 1; 1.5; 2; 2.5. The second stage of testing was carried out using a geopolymer paste with the highest compressive strength, namely the ratio of NaOH to Na2SiO3 of 2.5 with a compressive strength of 22.56 MPa. Based on the results of the compressive strength test, the maximum compressive strength at the age of 28 days is 7.64 MPa. The results of the compressive strength of concrete are much lower than the compressive strength of the paste, it shows that the paste does not bind too much with the aggregate. This is evidenced by the results of the compressive strength of conventional concrete which is much higher than that of geopolymer concrete using the same aggregate. With the results of the maximum compressive strength at the age of 28 days is 29.51 MPa.

One of the innovations in the use of glass waste in the construction sector is as a mixture of concrete brick. In this research glass dust from a building demolition in the Klandasan area of ??Balikpapan was used as a substitute for sand in a mixture of concrete brick. This research aims to analyze the use of glass powder as a substitute for sand in a mixture of concrete brick based on SNI 03-0349-1989. Concrete brick specimens are made with a cement and sand ratio of 1: 6. The variation in the replacement of glass powder used is 0%, 25%, and 50% of the composition of the sand. From the results of the analysis it was found that the water absorption capacity of the concrete brick with the addition of glass powder to the mixture of the concrete brick as a substitute for sand in the 0% concrete brick glass powder was 5.13% greater than the variation of 25% glass powder and 17.1% greater than the 50% variation of glass powder. The compressive strength of the concrete brick making with the addition of glass powder as a substitute for sand in the mixture of the concrete brick compressive strength of 25% glass powder is 11.11% better than oncrete brick 0% glass powder and compressive strength of the concrete brick 50% glass powder is better 33.33% than concrete brick 0% glass powder.

Floods that occurred in the city of Banjarbaru especially those that occurred in residential areas caused problems for the community as well as challenges for the government to evaluate the drainage channel in the settlement. The existing rainwater drainage channels need to be reviewed and developed so that they can accommodate the water flowing in the area. One of the settlements that had occurred in the city of Banjarbaru was a residential area in Cempaka Subdistrict, Cempaka Village, precisely on Jalan Getah Tunggal. The data needed in this study are rainfall data, land use data, topographic data and existing data on channel conditions at the study site. Rainfall data were analyzed by Log Pearson III, Gumbel and Iwai Kadoya methods, then tested by Chi Square to choose the distribution of statistics received. The rainfall data was analyzed into the intensity of hourly rain using the mononobe method. Rain intensity is analyzed using a rational method to get a plan debit (Qchannel). Furthermore (the plan) is compared with (Qchannel), and (Qexisting). Based on the calculation results obtained (Qplanning) of 0.76 m3/sec, (Qchannel) of 0.78 m3/sec, (Qexisting) of 0.0645 m3/sec, the comparison results are obtained (Qchannel)>(Qplanning), (Qexisting) <(Qplanning). So that it can be concluded that the causes of flooding and inundation are sediments as high as 70 cm which reduce the storage capacity of the initial dimensions of the channel

The existing rainwater drainage channels need to be reviewed and developed so that they can accommodate the water flowing in the area. One of the settlements that had occurred in the city of Banjarbaru was a residential area in Cempaka Subdistrict, Cempaka Village, precisely on Jalan Getah Tunggal. The data needed in this study are rainfall data, land use data, topographic data and existing data on channel conditions at the study site. Rainfall data were analyzed by Log Pearson III, Gumbel and Iwai Kadoya methods, then tested by Chi Square to choose the distribution of statistics received. The rainfall data was analyzed into the intensity of hourly rain using the mononobe method. Rain intensity is analyzed using a rational method to get a plan debit (Qchannel). Furthermore (the plan) is compared with (Qchannel), and (Qexisting). Based on the calculation results obtained (Qplanning) of 0.76 m3/sec, (Qchannel) of 0.78 m3/sec, (Qexisting) of 0.0645 m3/sec, the comparison results are obtained (Qchannel)>(Qplanning), (Qexisting) <(Qplanning).

The problem of providing clean water is currently a special concern for developed countries and developing countries. Indonesia as a developing country cannot be separated from the problem of providing clean water for its people. One of the main problems faced is the lack of available sources of clean water, the uneven distribution of clean water services, especially in rural areas and existing clean water sources that have not been utilized optimally. This study aims to analyze the clean water needs of PDAM Samboja which uses 2 pumps in the next 10 years (2028). By using primary and secondary data obtained from PDAM Samboja and a number of related references, it was found that the IPA clean water needs of PDAM Tirta Mahakam Samboja with 2 pumps, in 2018 amounted to 2,599.5 m3/day. With the estimated results of the number of customers in the next 10 years (2028), the number of water requirements is 3,048 m3/day. Therefore it is necessary to add 1 pump to the PDAM Samboja IPA so that it can still serve the needs of customers in the next 10 years
