Abstract

A pillar is a substructure located in the middle of the span between two abutment which also functions to carry the loads of the superstructure  and other buildings and transmit them to the foundation and distribute them to hard subgrade. Local scouring around building occurs because the local flow pattern around river buildings is a natural process that occurs in rivers duet o the influence of river morphology or the presence of water structure that block flow, for example brodge bases, brodge pillars, abutments, river cribs, etc. The presence of these water structure cdauses changes in flow characteristics such as flow speed and turbulence, giving riset o changes in sediment transport and the occurrence of scour. Research objective: to determine the scour pattern around the foundation pillars of sungai lais harbour and effective ways to control scour. Research method: experimental by collecting primary data and secondary data. Also, research was carried out through practicums using miniature rivers.the results of research obtained the magnitude by observing the flume (channel) during the running test/ stream flow and then research was carried out on the magnitude of the channel’s base elevation before it was channeled and changes in the depth of scour after it was channeled affecting the foundation pillars above. This is influenced by the speed of the water flow, the collapse rate is also not very significant. The collapse of the outer waa occured when the flow time was 10 minutes at the end of data collection. So, the factor that influences the size of the scour around the pillar is the speed of the following flow and the material deposits carried by it.  Keywords : A Pillars, Scour, Flow Speed

Abstract

Geopolymer mortar is an alternative material to replace Indonesian portland cement. Made from a mixture of rice husk ash and fly ash without using cement, utilizes industrial waste and is environmentally friendly. This study analyzes the effect of sugarcane bagasse substitution on mortar setting time and compressive strength of geopolymer mortar in fly ash-based mixtures. The benefits include increasing the additional value of bagasse fly ash as a mixture and reducing the use of cement material in mortar. Become a reference for other researchers. This research shows that the results of the substitution of bagasse for fly ash have an effect on the hardening time and strength of the mortar. The hardening time meets the standards for initial sett, but not for final sett. The greatest effect occurred at a percentage of 15% with an initial set hardening time of 90 minutes and a final set of 135 minutes. Mortar strength continues to increase from 7 days to 28 days at each percentage, with the highest value at the 15% percentage of 10.4 Mpa.

Abstract

Roads are land transportation infrastructure that includes all parts of the road, including complementary structures and equipment, intended for traffic, located on the ground surface, above the ground surface, underground, and on or under water surfaces, excluding railroads, tramways, and cableways. The function of highways as transportation infrastructure in economic activities is to promote economic equity by serving as a connecting network. Rehabilitation is the solution to damages caused by excessive vehicle loads and frequent changes in weather and climate. Road rehabilitation involves resurfacing, restoration, and rehabilitation of existing pavement layers to extend their service life, improve performance, and enhance the durability of pavement structures. To restore the service conditions of roads, regular maintenance is essential. One type of road maintenance is road improvement, which may include upgrading pavement structures or widening roads to increase their capacity. The implementation of road rehabilitation on Jalan M. Isa is a critical effort to improve vital urban transportation infrastructure, given the high levels of damage in several sections caused by aging, traffic loads, and weather conditions. The government builds transportation infrastructure according to the needs of each region to foster regional development. This study examines whether the road rehabilitation methods applied on Jalan M. Isa comply with existing technical standards and align with the 2023 General Specifications of Bina Marga. The type of asphalt used in the rehabilitation of Jalan M. Isa in Palembang City is AC-WC (Asphalt Concrete Wearing Course), with damage assessments conducted using the PCI (Pavement Condition Index) method.Keywords: Road rehabilitation, M.

Abstract

Bamboo is a plant that can be found around us, especially in rural areas. Bamboo is an environmentally friendly building material compared to conventional building materials. In addition to being easily accessible, cheap, and lightweight, bamboo also possesses considerable strength. There have been numerous studies on the use of bamboo, but in this research, bamboo is utilized as a substitute material for coarse aggregates. The planned compressive strength is for concrete with a compressive strength of K250 (20.75MPa) with substitution proportions of 30%, 50%, and 100%, which will be compared with normal concrete. In this study, it is expected to determine the proportion of substitution of coarse aggregates in concrete using bamboo. Based on the tests conducted, ranging from testing concrete-forming materials to compressive strength tests, the compressive strength obtained for normal concrete (0%) at 28 days is 26 MPa. Meanwhile, the compressive strength for concrete with a 30% substitution proportion is 26 MPa, 50% proportion is 13 MPa, and 100% proportion is 9 MPa. Thus, it can be concluded that the greater the percentage of concrete substitution, the lower the compressive strength obtained.

Abstract

The SPBI 2×200 KL construction project, initially planned to be completed in 360 days, experienced significant delays in the 21st week, with a progress deviation of -16.434%. To address this issue, the Time Cost Trade Off (TCTO) acceleration method was implemented by adding 4 hours of overtime work per day. This strategy successfully shortened the project duration from 336 days to 231 days, reducing the total project time by 37%. The acceleration efforts were focused on critical paths that influenced the project's completion. Although there was a 17.1% increase in direct costs due to overtime wages, additional labor, and extra materials, the application of TCTO effectively reduced indirect costs associated with prolonged project duration, such as administrative and operational expenses. Overall, this method proved to be effective in bringing the project back on schedule and preventing further losses due to delays.
