Construction materials are very significant spending in a construction project. They may create losses to Implementation Budget Plan (IBP) whenever the number is excessive. This paper is intended to find causes of redundant materials for guidelines to next projects to avoid excessive number of redundant materials. This paper details driving factors to material redundancy, total value of redundant materials and percentage ratio of redundant materials total value over IBP value. To obtain those factors causing redundant materials, this research run a set of questionnaires referenced from journals and refined by expert professionals. The questionnaires set was then handed to managerial peers and other non-managerial respondents to acquire their responses. The questionnaire outcome provides clues on major driving factors. They are lack of control at site, lack of supervision and lack of allocated facility for redundant materials. Further studies in this paper using price details in IBP and unit conversion on redundant materials have come to a material redundant value of Rp. 383.940.000 from an IBP value of Rp. 31.125.169.000. The highest percentage ratio of redundant materials is from ceramics fitting works at 34.18% while total value percentage ratio of redundant materials over IBP is 1.23%.

International Journal of Civil Engineering and Infrastructure Vol 1, No 1 (2021): IJCEI Volume 1 No. 1
Publisher : University Of Muhammadiyah Jakarta

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.

Innovation in obtaining construction materials that are efficient and applicable to various conditions is a challenge for researchers. Cold-formed steel is a material breakthrough in construction that has advantages over hot-rolled steel. Many studies have been carried out on Cold-formedsteel subjected to various loadings to examine the behavior and capacities of the sections. This study aims to investigate the behavior and section capacity of cold-formed steel unlipped channels due to axial compression loads. This research begins with conducting a literature study, then carrying out numerical analysis using the finite element method in ABAQUS, numerical test, and calculation of section capacity based on existing research in the literature. The calculation of section capacity is carried out based on SNI 7971-2013 or AS/NZS 4600:2005. The results of the numerical analysis can be seen from the behavior and capacities of the sections of the unlipped channel, the section capacity from the numerical test will be compared with the section capacity obtained from the calculation based on SNI 7971-2013 or AS/NZS 4600.

WHAT ACTUALLY DRIVE CONSTRUCTION PROJECT PERFORMANCE FROM OPERATIONS MANAGEMENT PERSPECTIVE Rachmad Irwanto
International Journal of Civil Engineering and Infrastructure Vol 2, No 1 (2022): IJCEI Volume 2 No. 1
Publisher : University Of Muhammadiyah Jakarta

Construction industry is always an interesting discussion topic. Some have it approached from its planning and scheduling view accommodating risk analysis. Other interesting topics related to construction industry are its business model, organization and operations. The author argues that construction is a function of them all. An emphasized study on a specific topic above would be less relevant given the fact that construction industry is highly fragmented. From literature review, factors such project integration, communications, knowledge and understanding, human resources, safety, financial, and cost management drive more significant impact on project scheduling performance

Research and development of construction materials continue to be carried out, getting materials, cross-sectional shapes, and manufacturing methods that are more efficient than before. Cold-formed steel is a material breakthrough in construction that has advantages over hot-rolled steel. In this paper, the cross-section of cold-rolled steel unlipped channel will be analyzed which is subjected to a combination of axial and bending loads. Investigating elements will be carried out using the finite element method on ABAQUS, and the results of the analysis produce a visualization of the behavior and capacity of the cold-rolled steel section. The cross-section capacity results obtained from the numerical test results will be compared with the predictions given by SNI 7971-2013 or AS/NZS 4600. Existing research in the literature will be used as a reference in conducting numerical analysis and calculating ultimate capacities.

Evaluating the perception of structural defects during implementation of RC T-beams Elsaid Bayoumi
International Journal of Civil Engineering and Infrastructure Vol 2, No 1 (2022): IJCEI Volume 2 No. 1
Publisher : University Of Muhammadiyah Jakarta

Most defects during construction projects are due to human errors which happen due to poor workmanship. This study involved 8 simply supported RC T-beams subjected to uniformly distributed load at both-edges of slab. The investigated parameters were the effect of malposition of slab reinforcement, unequal configuration of slab reinforcement and change in bar diameter of slab reinforcement. The experimental results showed that; malposition of slab reinforcement leads to a lower load carrying capacity of the slab and consequently flexural resistance decreased and slab deflection increased. The irregularity of the reinforcing bars in concrete slab affected the load carrying capacity of T-beam. Well-arranged distribution of reinforcement improves the ductile behavior of slab and reduced value of deflections at failure. Using reinforcing steel bars with diameters higher than 8mm in the reinforcement helped the slab to withstand more loads. The use of 10mm diameter in reinforcement of the slab enhances the serviceability of T-beams.

CANAL CAPACITY IN AREA IKIP AND PULOMAS Budi Satiawan; Puspita Maratus Sholeha
International Journal of Civil Engineering and Infrastructure Vol 1, No 1 (2021): IJCEI Volume 1 No. 1
Publisher : University Of Muhammadiyah Jakarta

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

The channel in the Buaran River area has a channel length of 5.32 km located in the Bukit Kencana Housing Area as the upstream of the Buaran River with the smallest cross-sectional width of 0.9 m and a height of 1 m and the border of the Jakarta Cikampek Toll Road as a downstream with a width of 2.2 m and a height of 3.6 m. one of the areas of the Buaran River which experienced quite severe flooding. This was due to changes or conversion of land functions which were originally water catchment areas to settlements. The large number of buildings that stand on the body of the river makes the current section of the Buaran River unable to function optimally in accommodating flood discharges, besides that there is no public awareness in protecting the environment which can be seen from the many piles of garbage in the body of the river. The purpose of this research is to find out how big the capacity of the existing Buaran cross-section is (starting from the Bukit Kencana Residential Area to the Jakarta Cikampek Toll Road) by modeling the existing cross-section using the help of the Hec-Rass application as well as recording and mapping locations that have the potential to flood. . One of the efforts that have been made by the government in controlling floods is by normalizing the river but in practice, the normalization of the Buaran River cannot be said to be running optimally. Based on hydrological calculations, the planned Q25 flood discharge is 16,307 m3/s. By using the help of the Hec-Ras application we can find out which river profiles need to be treated so that the handling of river normalization as an alternative to flood control can run optimally

EFFECTIVENESS OF GOVERNMENT’S ELECTRONIC PROCUREMENT OF GOODS AND SERVICES IN ITS ROLE WITHIN THE GOVERNMENT’S PROJECTS Yan Ari Wibowo; Trijeti Trijeti; Rachmad Irwanto

The government’s goods and services procurement are the major part in the state budget realization for its impact on performance of government’s departments. Considering the growing number of goods and services procurements, the government rules to set the procurement of goods and services electronically. This helps the government to run the state budget realization that is good in timekeeping, efficiency and accountability during procurement process. The effectiveness of electronic procurement of goods and services (e-procurement) of the government is strongly related to the government’s projects. This is presented in this study using a descriptive quantitative method on processed data output from SPSS v.23. The data was sourced from recorded government’s project in LKPP in 2019. The result shows good effectiveness level at 65,9% with supporting strong correlation value at 0,812 following consummated budget at 95,71%. Based on those statistics, this paper suggests that the run of government’s projects automatically would induce a consummated budget in which targets would be achieved and provide more benefits. Therefore, a good run of government’s projects needs better effectiveness of the government’s e-procurement of goods and services.
