Abstract

In the construction of a building, it is necessary to plan a concrete structure that can make us feel safe and comfortable. The concrete structure itself is very close to making a slab and beam, the design and implementation of a slab and beam has many innovations in the manufacturing process. One of the information during the construction of the structure is formwork with a fixed shoring system. Where when the formwork can be removed quickly enough from the usual time, this will cause a reaction on the structure itself and the fix shoring is the part that reduces the impact of the reaction. The purpose of this study was conducted to find out whether the fix shoring system formwork is able to provide safe results according to the building permit. The fix shoring method based on the results of the analysis obtained, the floor slab concrete structure was able to withstand the deflection that occurred on day 2 (2.891 of the maximum deflection of 8.333). Meanwhile, the elastic deflection only met the requirements on day 3 (Mu<Mcr, 8.729 kN/m < 8.700 kN/m). For the concrete structure itself has a size of 40x70 and 30x70. The conclusion is that the overall results comply with the specified permits from the pedestal to the field. It can be stated that the formwork of the fixed shoring system, on the 3rd day, the formwork can be removed without affecting the state of the concrete structure.

Abstract

Research in the concrete industry aims to improve the quality of concrete using advanced technology and techniques. One of the innovations carried out is the use of additional materials in SCC concrete, namely coconut shell ash. This research uses coconut shell ash as an additional material with the proportion of coconut shell ash used being 0%, 5%, 15% and 25% of the cement weight with a maximum aggregate accuracy of 20 mm. The reference used in making the concrete mix is the EFNARC Mix Design with a design compressive strength (f'c) of 20 MPa. The test object is cylindrical with a diameter of 15 cm and a height of 30 cm. The tests carried out were compression tests with treatment for 14 and 28 days. The results of adding coconut shell ash to SCC concrete have an influence on the workability characteristics of concrete in the form of a maximum slump flow value in the SCC0 concrete variation without additional coconut shell ash of 650 mm and a minimum slump flow value found in the unmixed concrete (BN) variation of 330 mm and The results of the v-funnel test experienced a decrease in flow time as the coconut shell ash increased, this was caused by the higher the percentage of coconut shell ash used, the thicker the concrete properties would be. The results of the comparison value of unmixed concrete (BN) and SCC concrete with variations in the addition of coconut shell ash to the compressive strength of concrete at the ages of 14 and 28 days showed a decrease in the compressive strength value of concrete along with increasing the percentage of coconut shell ash used. The highest decrease in the compressive strength value of unmixed concrete (BN) occurred in the SCCA25 variation, 55.50% at 14 days and 61.06% at 28 days.

Abstract

Sistem struktur rangka baja bresing konsentris dan eksentris merupakan sistem struktur konstruksi yang termasuk dalam struktur yang tahan terhadap beban gempa. Pada penelitian ini, masing-masing sistem struktur rangka baja bresing konsentris dan eksentris tersebut dianalisis dengan model perletakan yang berbeda-beda mulai dari struktur dengan perletakan sendi, jepit, dan struktur yang menggunakan base isolator. Model struktur juga divariasikan dengan jumlah tingkat yang berbeda yaitu tingkat 3, 4, dan 5, namun dimensi lebar dan panjangnya dibuat sama. Tahap awal yang dilakukan pada penelitian adalah melakukan preliminary design dan pemodelan struktur. Kemudian dilanjutkan dengan penentuan data gempa riwayat waktu di permukaan. Setelah itu, dilanjutkan dengan penentuan parameter base isolator struktur, dan kemudian melakukan analisis struktur. Hasil analisis struktur menunjukkan kenaikan rata-rata periode struktur rangka bresing konsentris (SRBK) dari perletakan sendi dan jepit masing-masing adalah sebesar 2,20 dan 2,32 kali jika menggunakan perletakan base isolator. Sedangkan kenaikan rata-rata periode struktur rangka bresing eksentris (SRBE) dengan perletakan sendi dan jepit masing-masing adalah sebesar 2,07 dan 2,20 kali jika menggunakan perletakan base isolator. Selain itu, penggunaan base isolator pada struktur SRBK dan SRBE dengan jumlah tingkat dan periode struktur yang lebih tinggi akan membuat struktur akan lebih fleksibel dan belum tentu membuat struktur SRBK dan SRBE tahan gempa, namun dapat mengontrol struktur tersebut sehingga terhindar dari periode struktur dalam kondisi resonansi yang berbahaya.

Abstract

The Jabodetabek commuter rail is an essential supporting public transportation system connecting suburban areas to city-centre workplaces. Determining service coverage is one thing that needs to be considered in a transit service availability system. This research tries to increase the range of services with park-and-ride and ridesourcing facilities at Jabodetabek commuter rail station locations in suburban areas. This is expected to increase interest in using the Jabodetabek commuter rail. For this reason, quantitative performance is needed to state what factors influence the service area coverage of a station in suburban areas, which are analyzed using the multiple linear regression method. Station service coverage is measured by the length of the journey from the place of residence to the starting station for Jabodetabek commuter rail users, with the station of origin of the trip being Tenjo Station and Tigaraksa Station, using the perspective of distance and travel time from the place of residence to the station of origin of the trip. The estimation results show that the radius of station service coverage, namely the travel time from residence to the station of origin of the journey (minutes), has a higher coefficient of determination than the distance from residence to the station of origin of the journey (km). Apart from that, 9 (nine) factors were identified that influenced travel time from residence to the station of origin of the journey (minutes). In contrast, the distance from residence to the journey's origin (km) station was identified as 6 (six) factors. Then, the estimated tolerance value for the station's service range is obtained in the range of 0.5-9.0 km and 5-26 minutes.

Abstract

The calculation of the cost budget by consultants mostly uses Microsoft Excel. This causes opportunities for errors due to inaccuracies in interpretation and calculation in elaborating the complexity of the building to be built. Calculations that still use excel in development projects where it can result in a much larger calculation difference resulting in cost overruns. For this reason, it is necessary to require more effective cost estimation planning. One of the latest project management information systems today is Building Information Modeling (BIM). BIM has great potential to share visualize information, visualize construction progress, provide information quickly. Therefore, this research uses BIM 5D (Autodesk Revit software) which functions to estimate the cost budget of a project. The Plan Budget Cost (RAB) figure will not be 100% accurate. The purpose of this study is to determine the comparison and difference in volume calculations and RAB using BIM 5D dimensions with calculations of Planning Consultants on Reinforced Concrete Works in the Office and Post Security Depot Supply Point Pertamina Lubricants Tarakan Construction Project. The results of the calculation with BIM 5D method and the Planner Consultant obtained the results of the calculation of the difference where the comparison of the volume of reinforcement is a difference of 3.83% while in concrete work the difference is 4.37%. Meanwhile, the results of the RAB calculation on reinforced concrete work cost difference of 4.10%.
