Abstract

Self Compacting Concrete atau biasa disingkat dengan SCC merupakan beton inovatif yang dapat memadatkan sendiri (tanpa vibrator) dan mampu mengalir dengan beratnya sendiri untuk mengisi bekisting dengan jenuh tanpa mengalami segregasi. Material dari SCC tidak jauh berbeda dari beton normal, yaitu Agregat Halus , agregat halus, semen, air, hanya saja pada SCC terdapat bahan tambah admixture berupa superplasticizer. Dari hasil pengujian Agregat Halus didapat kesimpulan bahwa hasil pengujian kuat tekan beton SCC umur 7 hari menggunakan 3 sampel benda uji, dengan masing masing hasil yaitu SCC-martapura-7hari sebesar 32,45 Mpa, lalu SCC-tanjunglubuk-7hari sebesar 35,05 dan SCC-perjito-7hari sebesar 34,77. Dan SCC-martapura-28hari sebesar 42,24, lalu SCC-tanjunglubuk-28hari sebesar 42,19, dan SCC-perjito-28hari sebesar 42,13.Keywords: Agregat Halus, Self Compaction Concrete

Abstract

Building construction found in Indonesia generally uses concrete as its main structural material, the need for concrete in construction is very large. This is because concrete has many advantages when compared to other building materials. Especially concrete that has high compressive strength. According to the general specifications of Bina Marga (2018) revision 2, Concrete is a mixture of Portland cement or equivalent hydraulic cement, fine aggregate, coarse aggregate, and water with or without additives to form a solid mass. Concrete is also widely used in building construction because it has advantages including being easy to form according to plan, raw materials or concrete components are easy to obtain, durable, fire resistant, easy and relatively cheap maintenance costs and concrete is a structure that has high compressive strength. So researchers are interested in conducting research using geogrids to analyze the effect of geogrids as additives in concrete mixtures. And because the weakness of concrete is its low ability to withstand flexural strength, in this study the researcher will analyze the effect of geogrid as an additional material for fs'45 concrete on the flexural strength of fs'45 concrete and analyze the comparison of normal fs'45 concrete with FS 45 concrete with geogrid additional material.Keywords: Geogrid added concrete

Abstract

Palembang City is the capital city of South Sumatra Province with a population of 1,718,440 people in 2024. The Kambang Iwak area is one of the recreational areas in Palembang City which is located in the city center. With a relatively large population in Palembang City, an adequate recreation area is needed so that there is no accumulation of people in an existing recreation area. The accumulation of people causes a buildup of vehicles which can disrupt traffic flow. The survey was conducted at the Talang Semut Intersection which connects 4 roads, namely Jalan A Rivai, Jalan Ki Ranggo Wirosantiko, Jalan KH Ahmad Dahlan and Jalan Jaksa Agung R Soerapto. The survey was conducted for 7 days starting at 06.00 - 18.00 WIB which was carried out in the Kambang Iwak Area, namely at the Talang Semut Intersection. It can be seen that the highest traffic volume at the intersection occurs on Sunday mornings. After the survey was conducted, the data obtained was analyzed with reference to the 2023 Indonesian Road Capacity Guidelines (PKJI). Based on the results of the analysis, the level of service at the Talang Semut Intersection was E.Keywords: PKJI 2023, Traffic Volume, and Intersection Performance

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

Roads function to connect one region to another to share needs, both in economic, social, cultural, governmental and so on. In implementing the road pavement structure, special considerations need to be taken in planning the mixture of coarse aggregate (course aggergate) and fine aggregate (fire aggergate) and filler. One type of pavement layer used in Indonesia is (Laston) asphalt concrete layer mixture. Asphalt Concrete Layer (LASTON) is a layer in road construction consisting of coarse aggregate, fine aggregate, filler and hard asphalt, which are mixed, spread and compacted hot at a certain temperature. The purpose of conducting this research is to determine the effect of using MSE Wall (Corner Stone) Coarse Aggregate (Corner Stone) as an AC BC Asphalt Mixture on Marshall Parameters. This type of research is experimental research, the results of research on the Asphalt Concrete-Wearing Course (AC-WC) mixture with concrete fragment waste as a substitute for coarse aggregate with grades 0% 25% 50% 75% and 100%. The effect of MSE Wall concrete fragment waste as a substitute for coarse aggregate based on Marshall test parameters shows that the optimum value is at an asphalt content of 5.75% and a concrete fragment waste content of 25%, namely with a Stability value of 1056.4%, a Flow value of 3.24% , VFA 73.61%, VMA 16.37%, VIM 4.32%, and MQ 326.1%.

Abstract

DJKA LRT Station or called DJKA Station is the final station of the South Sumatra LRT cross service and is located on Jalan Gubernur H. Bestari (National Road). Currently, DJKA station does not have parking facilities but uses sidewalks and part of the road for parking cars and motorbikes for LRT station officers and bicycles for cycling passengers, which is contrary to existing regulations. Therefore, this study aims to plan parking facilities at DJKA Station both in terms of parking rates, parking space requirements and parking design with interview and preference survey methods and analysis of parking demand calculations. The results of the analysis found that parking preferences of station staff respondents and LRT passengers agreed and would use parking facilities with a type of tariff, namely a flat rate per entry per day of Rp. 2,000 for motorbikes and Rp. 5,000 for cars. Overall parking space requirements are 202 SRP for motorcycles, 61 SRP for passenger cars gol. II, 1 SRP for vehicle car gol. III and 1 bicycle parking facility measuring 4m x 2m. By considering the availability of land and parking space requirements, the location of the parking area used is in the area west of DJKA Station and with an island parking pattern, a parking angle of 90 °, and the number of parking counters of 1 counter for both motorcycle vehicles (ρ value = 0.075 < 1) and car vehicles (ρ value = 0.003 < 1).Keywords: DJKA station parking, parking space, parking rates, parking design.
