Abstract

ABSTRACTRigid pavement for highways in Indonesia started as an alternative for road pavement. Roller compacted concrete (RCC) is one type of dry concrete mixture with low water cement ratio (slump 5 cm). The RCC spreading is the same as the asphalt concrete pavement that uses the finisher and is compacted using a roller. This research uses RCC mix design with cement water factor value 0,25. Additional silicafume materials of 10%, superplasticizer 2.4%, and steel fiber (dramix) with variations of 0.5% and 1%. RCC Compaction using standard proctor tools. Testing of bending forces and compression of concrete in 1 day and 28 days. The result of research of RCC variation of 0.5% steel fiber and 1 day old concrete obtained Flexural Strength of 4,2 MPa while 28 days concrete gained Flexural Strength of 5,7 MPa. The variation of 1% steel fiber 1 day concrete obtained 3.4 MPa Flexural Strength, while the 28 days  concrete obtained 6.1 MPa Flexural Strength.Keywords: Roller Compacted Concrete (RCC), Steel Fiber (dramix), Flexural Strength ABSTRAKPerkerasan kaku di Indonesia semakin banyak digunakan sebagai alternatif perkerasan jalan raya. Roller Compacted Concrete (RCC) atau beton padat giling (BPG) merupakan salah satu jenis campuran beton kering dengan faktor air semen (FAS) yang rendah (slump 5 cm). Penghamparan RCC sama seperti penghamparan perkerasan beton aspal yang menggunakan finisher dan dipadatkan menggunakan roller. Kajian ini menggunakan mix design RCC dengan nilai faktor air semen 0,25. Bahan tambah silicafume sebesar 10%, superplasticizer 2,4%, dan serat baja (dramix) dengan variasi 0,5% dan 1%. Pemadatan RCC menggunakan alat standar proctor. Pengujian kuat lentur pada beton umur 1 hari dan 28 hari. Hasil kajian RCC variasi serat baja 0,5% beton umur 1 hari diperoleh kuat lentur 4,2 MPa, sedangkan beton umur 28 hari diperoleh kuat lentur 5,7 MPa. Variasi serat baja 1% beton umur 1 hari diperoleh kuat lentur 3,4 MPa, sedangkan beton umur 28 hari diperoleh kuat lentur 6,1 MPa. Kata kunci: Roller Compacted Concrete (RCC), Beton Padat Giling (BPG), Serat baja (dramix), Kuat lentur

Abstract

The integration of intermodal transportation services is a strategic necessity for improving the quality of urban transportation services. To realize the integration of services, it should be focused on the main transportation nodes in an area, such as Poris Plawad Terminal and Batu Ceper Station in the Poris Plawad Area, Tangerang City. This study aims to evaluate and determine strategies for improving the integration of intermodal transportation services in the Poris Plawad Area. The results of this study are expected to provide consideration for stakeholders to encourage the use of public transportation and realize the successful development of the Poris Plawad Area in the future. The sampling technique used was purposive sampling, with a total sample size of 202 respondents. Respondent data collection was carried out by distributing questionnaires to users of transportation services at Poris Plawad Terminal and Batu Ceper Station, as well as residents who are active within a radius of 800 meters from the terminal and station. This research uses the Importance Performance Analysis (IPA) and Theory of Inventive Problem Solving (TRIZ) methods. The results of the IPA analysis show that there are five service variables that are considered important but low-performing, so they need to be prioritized for improvement, including the provision of pedestrian crossing facilities, the provision of proper sidewalks, disturbance-free pavement quality, and access into and out of the node that is free from traffic conflicts. Recommended solutions based on TRIZ principles include building a sky bridge and closing the south entrance for access into and out of the station; building a sidewalk connected to the node that is built higher than the road surface and uses high-quality materials; placing sidewalk bollards; and permanently closing the station access point that passes through the railway level crossing. These improvements are expected to enhance accessibility, safety, and walkability, encouraging greater public transport use and aligning with the area’s Transit Oriented Development goals.
